Vitari SH v- Automatic Chain Welding Machine

The SH series of chain welding machines, allow to weld chains in one single stage by using a device which positions the chain link in the precise welding position. These machines can weld both high alloy or high resistance steel chains and cater for low and mild carbon, manganese and other diverse steel grades for chain making.

Vitari SH - Automatic Chain Welding MachineThe quality of the weld is of the highest standards available today due to the welding control system operating with medium frequency technology (1000 Hz). This allows a constant and high quality weld at all times and is a significant improvement (as well as a necessity for these high grade materials), compared to the standard frequency welding (50-60 Hz) available on our other chain welding models.

The quality of the weld is also guaranteed because the welding operation occurs on one machine instead of the conventional two machines. Therefore, once parameters are set and stored these will be suitable for all welded chain link requirements. The machine is equipped with a computer that enables monitoring all machine parameters even whilst the machine is operating and moreover, it allows loading and storing of every single type of chain parameter. The electrode unit is now fully adjustable as it now can be tilted upwards enabling full operator access when needing to intervene on the welding tools. The hot burr on the chain-link is removed by means of an intermittent tooling device which intervenes longitudinally along the chain-link leaving a burr-free finish. All machines are equipped with conventional safety devices in order to safeguard the principal parts of the machine.

Rebuilding the North American Power Transmission Infrastructure

As North America prepares to rebuild the crumbling infrastructure and increase the quantity of power transmission lines, decisions need to be made about how to get the power from the generation plants to the places it is required. Overhead transmission lines of 400 KV have significant environment impact. Therefore underground power lines are the best option. Underground transmission lines, Milliken Cables, are used when high voltage underground transmission when servicing highly populated areas around Cities, Airports, Power Generations plants, etc.

Rebuilding the North American Power

These conductors are large cross sections are obtained with composition of sectors. The pre-spiraled sectors are made separately on Rigid Stranders and as second phase are composed into one big cross section with the drum twisting line. The Milliken conductor is composed with 4 to 7 pre-spiraled compacted sectors. Each sector is separated from the adjacent with insulating or semi-conductive tapes. Frequently, a central round conductor is used and a water blocking tape is placed between the sectors layers. Cortinovis has developed rotating machines specifically designed to handle these large conductors. First the Cortinovis Rigid Cage Strander with rotating compacting heads and then the sector assembly using the Cortinovis Drum Twister with Rotating Payoffs.

Roll Tooling by EurollsEurolls is the world leader in the design and construction of roll tooling made of steel, alloys and sintered materials for the tube & pipe industry. Over the last few months of 2010 and the first half of 2011 Eurolls has strengthened its presence in the world market by securing large-scale contracts in terms of volume, and prestige. Major corporations, who themselves are world leaders in their respective field of manufacturing tubes for various applications, have chosen Eurolls as their roll tooling partner for major projects.

Eurolls - tube & pipe industryEurolls has been manufacturing roll tooling for markets worldwide for over 20 years. Over the last 5 years, Eurolls has established branches in Brazil and Mexico, and has seen the volume of work increased significantly at these respective subsidiaries over the last two years. Although Eurolls De Mexico and Eurolls De Brazil specialize in the sales, manufacturing, and regrinding services for rolls and cassettes for the Wire sector, the volume of work has significantly increased in terms of tooling for the Tube/Pipe sector. This is good news for those Tubing and Piping manufacturers who are in need of local production of tools with the same quality that they can to expect from the parent company.

Eurolls has recently integrated, within its own facility, the latest generation of furnaces for heat treatment, which gives them an advantage when it comes to quality control. Eurolls is extremely careful when calculating every step of the manufacturing cycle from selecting the very best raw materials, to developing their own design and manufacturing techniques, all the way to the production floor where strict quality controls and certifications are instituted in each and every phase of the roll manufacturing process.

SictraSictra Intergrated with Cortinovis Machinery SpA

In 2008 The Eurolls Group Udine, Italy announced that Sictra had become part of The Eurolls Group. Sictra has a long tradition and wide knowledge and experience in the manufacturing of wire drawing equipment for copper and aluminum.

Since the acquisition, Eurolls has proposed integrated product lines, using Sictra and Cortinovis Machinery, starting from drawing of copper or aluminium rod, through strand production, to laying‐up and armoring of finished cables. The wire and cable market reacted very positively to this strategic decision. The result has been a significant increase in both the volume of product, greater number of customers and an overall increase in market share for both technologies.

We are pleased to announce that we have taken the next logical step on the strategic path initiated in 2008. The Sictra drawing lines, which precede the Cortinovis stranding lines, have been fully integrated to provide complete plants for the nonferrous wire and electric cable market.

The formation of a single company will surround Sictra with a solid organizational structure whose ultimate goal is to provide its customers with high value‐added products and exceptional customer service.

On February 1, 2011, Cortinovis Machinery S.p.A. acquired the business and operating unit of Sictra Srl forming a corporation having two divisions:

  • Division of drawing lines for nonferrous (product line Sictra)
  • Division of stranding lines (typical product Cortinovis Machinery)

The operating unit of Sictra has been relocated to our modern production facility in Valbrembo. The necessary investments have been made to create additional office space and expand our production capabilities to integrate the discrete production needs of Sictra into our industrial group. Sictra staff can now take advantage of the Cortinovis facilities, technical departments, quality control, and technical service assistance, in order to focus on enhancing the Sictra technology and experience developed over several decades of activity. Sictra has also been integrated into the ERP system taking further advantage of the strong synergies between the two companies We are confident that the forming of the two divisions will have a positive impact on our customers in terms of product, service and competitiveness.

We also like to point out that your current Cortinovis and Sictra contacts in the respective commercial departments, spare parts department, and technical assistance personnel will direct your inquiries to the technical specialists in each area of expertise.

Cortinovis Machinery Delivers Next Generation of Tubular Strander for Steel

The Advantages in Cold Rolling with Cassettes, Compared to Traditional Dies.

Immediate increase in wire production
This is due to a reduction in downtimes or stoppages caused by die changes. Unfortunately due to their limited working life (approximately 40 tons as an average on all the blocks), and related wire pointing/welding processes (in order of 15 to 20 minutes per die per change) using Eurolls rolling cassettes can result in an increase in the efficiency of the process by 10 to 15% on average.

The Eurolls cold rolling cassette units use tungsten carbide rolls which have a working life, between regrinds, in excess of 2500 ton (small diameter tungsten carbide rolls) on last block and 5,000 ton on average on the other blocks for low carbon material.

Therefore, the line stoppages normally associated with the die substitution are reduced/eliminated and now become wire production times.

Eurolls - Cold RollingLower pulling force (or higher line operations speed)
The cold rolling principle requires a lower pulling force because of the different type of friction between the wire and the reduction tool (sliding-friction with dies and rolling-friction with cassettes). A typical value of sliding-friction is 0.18 and a typical value of rolling-friction is 0.04 for materials such as steel against hard metal. The reduction of pulling force consequent to the use of rolling cassettes is variable from 10 to 15% (depending on the entry material’s mechanical/chemical properties and the surface condition) when compared to the die-drawing process. This can be translated into either a lower energy consumption when operating at the same speed as with dies or higher achievable working speed when operating at the same energy consumption (and heat production) as with dies.

Reduction in wire breaks
The forces on the wire developed during the rolling process are lower than those on the drawing process and this quite often results in a reduction in the number of wire breakages (average reduction of breaks 7 to 10 times). This also will increase the efficiency of the process by an additional 5% on average.

Reduction of the cost for operating personnel
Due to the higher efficiencies achieved in the considerations made in points (1) and (2) and the savings associated with less die replacement for wear or wire breaks, a sensible reduction of operating personnel is achievable. One operator can easily attend to more than one drawing line, so that a saving of 30 to 50% of the personnel cost can be reasonably considered.

Reduction in lubricant consumption
Each die box is a source of lubricant consumption because it is required to lubricate both the dies and the wire (to reduce friction forces on capstan surface). The cold rolling cassettes do not need lubricant to perform the actual wire reductions. As mentioned above, only the first block will be fitted with a die-box (rotating) where the consumption of lubricant will represent 30 to 40% of that total used in a wire drawing line that is equipped with 100% dies. This means that the lubricant consumption figures, and therefore costs, can be reduced by 60 to 70% with the cold rolling process. A possible additional advantage could also be the smaller quantity of lubricant present on the wire surface.

This reduced quantity of lubricant could be an advantage when successive work cycles require a clean wire surface e.g. less residue formation/ deposit in the washing tanks just before galvanizing process etc.

Cold RollingLess air pollution
This major quantity of lubricant (see point 2 and 4) guarantees a reduction in the work place pollution levels as well and, as a direct consequence, the dimensions of the required dust exhaust and filtering systems.

Elimination of sophisticated/costly Rod Cleaning Processes and Salt Coating (Lime / Borax)
The tungsten carbide rolls used with the cold rolling cassettes, are insensitive to mill scale, surface imperfections and light surface rust. Simple and less expensive mechanical descalers can now be successfully used instead of more costly processes such as chemical cleaning (now environmentally unacceptable and expensive), blasting units (sand or scale) or complex descalers (brushing/belt cleaning with reverse bending etc.) A further salt coating of rod / wire is no longer needed as the salt function of the lubricant carrier is obviously superfluous.

Use of cold rolling cassette units into either new or existing wire production lines:
The insertion of the cold rolling cassette units into a wire production line (new or existing) does not require any modification to its mechanical or electrical components other than the simple insertion of a base plate for the cassette support. Therefore, the production line is able to produce the final exit wire using two methods – cold rolling or drawing. This means that all exit wire can be produced using the most cost efficient production method in accordance with the required dimensional/surface specification e.g. ovality tolerance, surface finish, lubricant coverage, etc.

The above are just some of the advantages that the Eurolls cold rolling cassette system has introduced to the field of wire production. This independent on whether the cold rolling cassette units are to be used with an existing or totally new wire production line.

NEW CONCEPT FOR MULTIWIRE WINDING AND UNWINDING

In many industrial applications, the previous or subsequent operation greatly impacts the overall efficiency of the process as a whole. This is especially true in the wire and cable industry where multi-wire technology is used. In this practice, special considerations must be taken to match the bunching technology with the processes of wire winding in the drawing line and of the wire unwinding in the bunching lines.

There are two accepted concepts for wire winding: dynamic spooler and static spooler.

Dynamic spooler: This is the conventional system of winding wire (or a bunch of wires), where the bobbin rotates around a horizontal axis and pulls and winds the wires around the drum of the bobbin known as a horizontal dynamic spooler. The bobbin is supported by a rotating shaft (cantilever design) or by pintles (shaft-less). In both cases the wires are distributed between the flanges by a traversing system with a small drive. No twist is given to the wires which are parallel wound. There are two versions of horizontal dynamic spoolers: in manual spoolers, the empty bobbin loading, the wires stringing onto the bobbin drum, the wires cutting and locking and the full bobbin unloading are performed by the operator. With Automatic spoolers all the above mentioned operations are achieved by automatic systems and controlled in sequence by the spooler PLC automation. After winding, the full bobbins are rolled out on their flanges and handled and stored with horizontal axis, usually lifting them from the central hole with a shaft. The unwinding in the bunching lines is also achieved in two different ways.

Sictra -  Multiwire LineFor the manufacturing of regular strands (7 or 19 wires) the paying off process requires the separation of the wires distributing them regularly in the buncher lay plate. This system utilizes a dynamic pay-off stand, which is driven because of the high bobbin weight and holds the reel on a horizontal cantilever shaft. Bunched random strands are produced utilizing the same pay off stands without the need to separate the wires prior to the lay plate. An alternative system utilized for bunched construction only (random strands) is the stationary pay off stand with a flyer arm rotating around the bobbin. In this case the wires cannot be separated in the buncher lay plate as they get a twist with each flyer turn. This system requires the bobbin be tilted as the axis is vertical. This system cannot match the same bunch quality achievable with the dynamic pay-off stands.

Static spooler: In those spoolers a large bell, containing the bobbin, rotates around a vertical axis and pulls and winds the wires around the bobbin drum. The wire distribution between the flanges is achieved by the vertical displacement of the bobbin (lifting and lowering) which requires a significant amount of energy due to the heavy weight of the bobbin holder, the bobbin, and the wire itself.

The rotating speed of the bell changes as the bobbin is built up, consequently also the centrifugal force of the wires through the entire wire path changes as well as the correlated wire stretching. All the wire paths require frequent cleaning (copper dust removal) and expensive maintenance.
An additional wire lubricator is needed at the spooler entrance.

The wires get a twist with each bell turn. These spoolers are automatic because the empty bobbin loading, the wires stringing onto the bobbin drum, the wires cutting and locking and the full bobbin unloading are automatic sequences controlled by the spooler PLC. The bobbins are handled throughout the machine (conveyors, winding station), laid on their flanges with vertical axis which makes subsequent factory handling and storing very convenient and easy.

Wire unwinding at bunching is accomplished by stationary pay off stands utilizing a flyer arm rotating around the bobbin axis. Wires can be separated at the lay plate for concentric regular strands (even if separation is more difficult with a stationary pay off stand than it is with a dynamic spooler and pay off stands) or kept together for random bunching. How to combine the advantages of the different techniques?

SICTRA has found the solution. A series of dynamic vertical automatic spoolers has been developed: the BOV 630 and BOV 800.

Sictra— BOV 630 & BOV 800.

Sictra - Vertical Dynamic Automatic Spooler with Rotating Spool -  Cortinovis America Representing

The bobbins are laid on their flanges, on their vertical axis, throughout the machine (conveyors, winding station) which makes subsequent factory handling and storing very convenient and easy like on the static spoolers. The spoolers are automatic: The empty bobbin loading, the wires stringing onto the bobbin drum, the wires cutting and locking, and the full bobbin unloading are automatic sequences controlled by the spooler PLC.

The variation of the bobbin rotating speed does not cause the wire to stretch which is an inherent problem on the static spoolers. The wires are distributed between the flanges by a simple traversing system with a small energy efficient drive. No twist is given to the wires which are parallel wound making it easy to separate the wires in the following operation. The bobbins are easily stored laid down on their flanges in stacks.

The unwinding in the bunching lines is achieved with specifically developed vertical dynamic driven pay off stands. Wire tension is adjusted via low inertia pneumatic dancers acting on AC motor drives fed by a common DC bus bar. Bobbin loading is easy and quick. No driving pin is needed since the bobbin is driven by the friction of its own weight. Wire separation at lay plate, when needed, is easy as wires are parallel wound.

Pay off stands are grouped in compacted racks. The combination of the vertical dynamic spooler and relevant driven pay-off stands summarizes the advantages of static spoolers over dynamic spoolers.

1. Handling is easy like with static spoolers
2. Automation is as efficient in static spoolers as it is in dynamic automatic spoolers
3. Winding is gentle like with dynamic spoolers
4. Power consumption is reduced like with dynamic spoolers
5. Maintenance is similar to dynamic spoolers, no wire passages need to be maintained on the rotating bell
6. No wire lubrication is needed
7. Wire separation on pay off stands is easy
8. Bobbin handling on pay off stand is easy
Overall dimension of the spooler and conveyors make it possible for them to be installed on lines replacing existing static spoolers

MARKET TREND—Trolley Wire for high-speed train applications is moving to Cu-Mg Wire

Trolly Wire for the FutureCopper Magnesium is a preferred alloyed-copper for high speed rail applications in many countries, as it provides good electrical conductivity and high tensile strength and good creep resistance. Additionally copper magnesium is also an enviromentally benign material with NO toxicity hazard.

From the manufacturing point of view, there is not a big difference in the drawing process, but the main difficulty of making trolley wire with Copper-Magnesium alloy is to be identified in the production of the rod for the following reasons:
1. The light and volatile nature of Magnesium
2. Magnesium’s propensity to form slag when molten
3. The need to maintain a very precise alloy composition in the wire rod
Copper-Magnesium trolley wire is now widely used in Western Europe, including on the high-speed TGV line from Brussels into France, Netherlands, Germany and Spain.

Cortinovis Machinery SpA has developed an apparatus for assembling compacted helically stranded unilay and cross-lay conductors for manufacturing compacted and trapezoidal conductors.  The pre-shaped individual segments are manufactured during the wire drawing Rigid Cage Stranderprocess. These segments are then wound onto bobbins and placed into a Rigid Cage Strander.  The apparatus is located at the exit of each cage of the Rigid Strander where the segments are oriented and assembled to produce a circular, highly compacted cross section, eliminating virtually all the interstices between the wires.

 Each individual wire is rolled to produce a trapezoidal profile wire starting from round having the correct cross section generated in the wire drawing operation. A Eurolls motorized cold rolling head is introduced between the exit of the wire drawing machine and the entrance to the spooler. This dancer controlled driven cassette rolls the round wire into the desired shape while pulling the wire without adding any additional pulling  tension in the  spooler. This unit can be added to the existing wire drawing operation without any changes required to the wire drawing machine or recalculation of the reduction dies in the wire drawing process.

Eurolls Report On Advantages of Cold Rolling Eurolls Report On Advantages of Cold Rolling

*Immediate Increase in Wire Production The increase in production is due to a decrease in down time or stoppages in the wire drawing process by using tungsten carbide rolls versus traditional draw dies because of fewer wire breaks.

*Lower Pulling Force or Higher Line Operating Speed —  The cold rolling requires a lower pulling force and therefore less horsepower due to the decrease in rolling friction between the wire and reduction rolls compared to sliding friction in conventional wire drawing.

*Reduction in Wire Breaks —  The pulling force developed during the rolling process is lower than in the drawing process for a given cross section of wire. This decrease in force results in a decrease in the number of wire breaks. This will increase the overall efficiency of the process by  an average of five percent.

*Reduction in Cost for Operating Personnel —  Since there will be less down time, an increase in roll life, and less wire breaks, there will be a reduction in the manpower requirements.

The advantage of using the EUROLLS Steel Fiber Machine, is its simplicity of operation which yields high performance and production.  Another advantage with using this machine, is that the tolerance range of the  inlet material is not crucial, therefore allowing you to utilize wire rejected from other processes into the final product with quality results and high market value.

Vitari - New High Tensile Bending Welding Calibrating Chain LineVitari SpA Introduces A New High Tensile Bending Welding Calibrating Chain Line

Vitari SpA  has introduced a series of high tensile bending/welding machines to make resistance welded chains used in Naval, agricultural, and automotive applications.  These machines are equipped with fully automatic welding, deburring and chain feeding devices. The welding operation is executed by means of four trapezoidal copper electrodes that receive current from a single phase transformer.  The deburring operation is conducted with two tools that intervene longitudinally on the hot chain. A special device subsequently intervenes to ensure a high quality burr-free welded chain link.  The tools located on the ends of the chain link have two distinct functions; first they shift quickly toward the chain ends and secondly a piston enables pressing of the chain link ends whilst welding is in progress. 

Team Meccanica Introduces New Direct Synchro Drive Wire Drawing Machine

Team Meccanica has developed a Direct Synchro Drive DSD 610/8 Wire Drawer.  This model is a ground-breaking Plug & Play Sychro Drive 610mm Drawing machine with 8 blocks, and is equipped with a pre-wired, mounted electrical cabinet which eliminates field wiring and commissioning. There are 45KW Synchronous Motors directly connected to the capstans which are cooled by a closed loop liquid glycol circuit.  There are NO gearboxes, NO belts, NO transmission and NO need for lubrication oil. 

Teuremal - Automatic SpoolerTeurema  S. L. EVM  Automatic  Spooler

The Teurema automatic spooler EVM was created for the production of precision laid wire coils with spools which can have a capacity of up to 5 tons. This double automatic spooler is composed of two spool working stations which are the wire collection station and the wire strapping/unloading/loading station. It comes complete with all of the necessary devices to ensure automatic handling of the wire, the cutting and subsequent threading of the wire, and the securing of the wire tail, too. All these operations improve line efficiency especially when operating with large diameter wires. The combination of all of these factors guarantees a drastic reduction in down times which are normally present during the spool changeover cycle. All parameters required for the formation of the pattern laid coil, as well as production information, are set on the spooler control pulpit.

Cortinovis  Redesigns  Double  Twist  Stranders  For  The Steel  Industry

Cortinovis Machinery recently redesigned their new Double Twist Strander, which has been specifically produced for the manufacturing of high quality steel strands.  The range of this machine allows the user to produce, utilizing the double twist process, strands from seven (7) up to thirty-seven (37) wires, with a diameter range from 0.1mm up to 2.6mm. 

The Cortinovis Machinery Double Twist Strander can be provided with multiple pay off designs, with the flexibility to adapt to the specific requirements of the bobbins’ diameter and the number of bobbins.  The strand is formed by two pre-twisters, with separate motors and deviation pulleys, before the product enters into the double twist machine.
