Stepless Speed 400/42+42 Armoured Cable Machine for Various Cable Specifications

1.Application:
This machine is mainly used for the production of low-carbon steel wire armor for large cross-section cables and non retreat twisting of aluminum alloy wires; It can also be used for non untwisted stranding of copper circular wire cores.

2.Overview of equipment composition
The entire machine is driven by a separate motor, and the hinge and traction are driven by separate motors. The hinge is driven to rotate through a dedicated gearbox. The control of the entire machine adopts Siemens S7-200 series PLC to ensure synchronization accuracy. In actual production, the operator can set the process parameters such as the pitch of each section of the twisted wire and the speed of the production line on the touch screen according to the required cable specifications. When starting up, the PLC automatically calculates the speed of each transmission part, ensuring the synchronization of the entire machine and the accuracy of the twisted wire pitch, and achieving stepless speed regulation of the entire machine.
The tension of the wire reel of the twisted body is controlled and adjusted by mechanical friction to ensure the stability of the wire reel tension.
The operation of the entire machine adopts Siemens S7-200 series PLC and fieldbus for unified control, coordinating the working status, operation, and speed control of various electrical parts of the machine. The operation touch screen adopts Siemens color human-machine interface to control operation.
