Full Production Line for Wire Drawing - Single Capstan Inverted Vertical Type Wire Drawing Machine with Automatic Wire Feeding & Shaving Machine

Large diameter wire rod automatic unwinder and feeder

Machine equipment is specifically designed to reduce the downtime of large wire preparation required for large diameter wire feeding. The equipment includes RGO series automatic wire rod unwinder with a straightening mechanism and RGV series sharpening unit for the front end of the wire rod coil. This equipment can work as part of a production line for wire drawing together with the RCD series inverted vertical drawing machine.

  • Traditional preparation time is approx. 30 minutes with pointing work; however using this equipment, the preparation time can be reduced down to 6 minutes.
  • From auto-feeding to pressing and striking, straightening, wire shaving, and then to Die end - all tedious work will be performed semi-automatically.
  • Wire shaving treatment process is automated with no physcial involvement of the operator with the wire rod. Contrary to the conventional method where the operator is always at risk of accident due to physcially holding the wire during pointing.
  • This automated machine equipment greatly increases production efficiency by up to 5 times by shortening wire rod preparation time.

Automatic decoiler for large diameter wire rod RGO series

automatic wire rod decoiler

Wire Rod Feeding:

  • SIEMENS or ТЕСО 7.5 HP AC Motor + Inverter.
  • Automatic Feeding.
  • Pedal Control for Jog / Forward / Reverse.
  • Wire Feeding Roller Controlled Automatically by Hydraulic Cylinder.
  • Radio Remote Control for Jog / Forward / Reverse.
  • Wire Rod Straightening: 2 sets of Straightening Rollers of "X" & "Y" Cross Direction.
  • Pressing Rollers: 3 Set of Hydraulic Rollers to provide a straight feed towards the straigtening rollers. Hydraulic pressing rollers with hardness treatment producing a surface hardness of HRC58°±2°.
  • Automatic emergency stop when a malfunction occurs, when the wire rod breaks, when the cover of the sharpening mechanism is opened.
  • Automatic stop during positioning of the sharpening mechanism.

Automated wire shaving machine RGV series

After straightening the wire rod in the straightening unit of the RGO decoiler, proceed to feed the wire to the RGV shaving machine.

Shaving machine will fixate the wire before shaving work can begin. Shaving work is fully automated, and once the shaving is complete, the machine will come to a stop, and the shaved wire end can be reversed out of the RGV equipment.

RGV shaving machine will then slide out of the production line, semi-automatically via railing. The wire rod is fed further into the drawing die.

The wire shaving equipment can work in the same line of equipment synchronously with the drawing machine.

For smaller sized diameter wire rod, use the manual POINTER. This manual method is much more efficient for pointing small diameter wire.

Wire Shaving Device Features

  • Fast shave time: 1.0m length takes about 5~10 mins (shaving time is dependent on wire diameter).
  • Produces an uniform round head for smooth insertion through the die, all the way to the automated hydraulic clipper.
  • Digital Control: relative to the wire diameter and shaving depth the control system will automatically adjust the rotational and feeding speed.
  • The uniquely designed turning tool adopts a reducer motor that drives the speed of the tool and feeding blade.
  • Left & right side each has 1 set of hydraulic cylinder for centering. This greatly helps optimize the shaving speed and the roundness of the wire head.
  • Pre-requisite process before wire shaving treatment: wire rod needs to be straightened before shaving treatment (straightened length must be longer than the shaving distance).

Wire Shaving Device includes

  • Segmented cross clamping device for fixed wire.
  • 1 set of 3 pcs guide wheel - clamping device - on the front and rear side of turning tool.
  • Lubricating motor: 1/2 HP
  • Hydraulic pump: 5 HP
  • Wire will be treated within specification of the drawing range.
  • Four blades to adjust simultaneously.
  • Hydraulic system to automatically move blades during wire head treatment.
  • Hydraulic trolley: 1 set (shavings waste collector).
