Welding line by bars

features and components | performance

The MESH LINE CO240-B-SERV line has been devised and manufactured to produce electrowelded wire mesh panels in standard size or according to the customer’s drawing for small or middle-small production lots where the operator needs to change type of wire mesh very often with very fast set-up times.
It is fed with line and cross wires by pre-straightened bars.
The line is available in two configurations:
Configuration 1 Configuration 2



Configuration 1

BEN-10T

Line-wire table:

Steel structure suitable to store line-wires up to 6 metres in length and maximum loading capacity of 10 tonnes.

ALL

Line-wires feeder:

It is a device that allows introducing line-bars into the welder.
An operator, who is between the magazine bench and the feeder, introduces the wires into the feeder which will automatically carry them, perfectly aligned, to the welder.
The operator introduces the wires while the wire mesh is being produced; therefore the productive cycle is not implicated.

The movement and introduction is servo-controlled.

CO-B-MULTISTEP

Mesh welding machine:

Steel structure where the welding transformers (from 6 to 12) and all accessories (lower and upper electrodes, welding presses, position electromagnets and so on) that allow welding of smooth and ribbed wires with diameter from 4,0 to 12,0 mm, are placed.
The forwarding movement of the wire mesh is driven by a servo-motor that moves forward a trolley carrying the pneumatic drawing grippers.

The operator can set the forwarding movement of the wire mesh (interaxis of the cross-wires) with 0.1 mm increases and guarantee of absolute exactness, from the control console.

ATR

Cross-wire feeder:

Steel structure assembled on track movable trolley. It feeds the welder in automatic mode drawing the cross bars from a big magazine (2 tonnes). It is equipped with n°2 servomotors; one moves the feeding disc and the other pushes the bar below the welding presses.
It is suitable for wires having diameters from 4 to 12 mm.

It can feed up to 140 bars per minute.

ACW

Automatic Cross Wires Feeding System (optional)

COM.IT has developed a new device to automatically feed the magazine loader "ATR" of the welding line called "CO-240-A".
The wires are held by two spools placed on rotating reels with pneumatic braking.
Towing and straightening are carried out by two straightening machines.
The cutting table and the support structure are designed so as to be able to straighten, cut and unload wires with length from 1400 to 2500 mm and a diameter from 3,0 to 10,0 mm.
ACW can be installed on new welding lines or in the revamping of existent plants.

CON-B

Electrical control cabinet:

the box is completely sealed and thermically conditioned, and it contains all necessary components to make the line work and to check it.

Control unit of the line:

touch screen display to:
  • Program the types of wire mesh to produce.
  • Store up to 100 different types of wire mesh.
  • Check and vary the production parameters.
  • Display production statistics
  • Display error messages

Control unit RIB6:

for the working and checking in manual or automatic of the turning-stacking unit.

ICE057

Water cooler:

This is a water cooling unit suitable to cool water at the exit of the welder (transformer, current cables and electrodes) and of the control board (SCR).

AIR300

Compressed air station:

It is made up with:
  • compressor
  • dryer
  • tank
  • filter
It is dimensioned according to the Customer’s requirements.

BAU

Wire mesh supporting bench:

It is suitable to support the wire mesh at the exit of the welder and to allow operators to extract it.

RIB6

Turning-stacking unit:

With this unit the operator can:
  • Extract the already cut panels from the welding machine
  • Turn and stack the wire mesh panels
This operation allows halving the size of the produced material, and saving money both in the storing and moving operations.

ROLL 6,5

Roller conveyor:

the motorized roller table, placed after the turning-stacking unit, allows having a station to tie and evacuate the produced wire mesh packs, with no need to stop production line.

INT240

Intermediate extractor:

This unit is necessary to extract the wire mesh panels from 2.500 to 4.000 mm in length.
