Factory Direct Supply Copper Wire Screening Shielding Machine Conductor Stranding Machine

Factory Direct Supply Copper Wire Screening Shielding Machine Conductor Stranding Machine​

Application:

This machine is mainly used to produce steel wire armor on the surface of large section wire rod; The coating material can be galvanized steel wire (round or flat steel wire)

MATERIAL : GI Round Wire / GI Strip/ Steel Round Wire/ Insulated Cores.

Feature:
The whole machine is driven by separate motors. Each section of the winch and traction are driven by separate motors and driven by special gear boxes
Compared with the traditional frame winch driven by the ground shaft, the structure of the winch is simplified and the equipment maintenance is more convenient.
Siemens s7-1200 series PLC is used for the control of the whole machine, and the production process parameters are set through the touch screen. Each section of winch and traction are driven by an AC variable-frequency motor, and the motor driver is a frequency converter device. In order to ensure the transmission accuracy, the transmission motor adopts grating encoder feedback, and the whole machine adopts bus communication to ensure the accuracy of signal transmission. In actual production, the user sets the process parameters such as the pitch of each section of the stranding body and the speed of the production line on the touch screen according to the required cable specifications. When starting up, the speed of each transmission part is automatically calculated by PLC, which ensures the synchronization of the whole machine and the accuracy of the pitch of the stranding wire, and realizes the stepless speed regulation of the whole machine. The electric control system has advanced technology, convenient operation and reliable operation.
Using digital quantity to detect the broken wire can accurately judge the broken wire signal of any disc in each section of the winch, and display which section and which disc is broken in the touch screen of the main console, which significantly improves the accuracy and accuracy of the broken wire detection and ensures the detection accuracy. Through the display in the touch screen, the operator can quickly solve the problem and start the next boot.
The reel tension of each section of the winch adopts a pneumatic proportional valve controller, which automatically calculates and tracks the reel diameter to adjust the reel tension, so as to ensure the stability of the reel tension. When starting up, the tension proportional coefficient can also be manually adjusted in the touch screen.
For the hanging operation of each section of the winch, an AC motor is used to drive the winch to rotate through the high speed ratio reducer for slow positioning. The AC motor is driven by Danvers frequency converter, and the frequency converter is controlled by bus.

The machine adopts imported Siemens s7-1200 programmable controller and PROFINET field bus to command and coordinate the electrical working state of all parts of the machine, and uses frequency converter to control the starting and operation of AC motor. Siemens color touch screen is used to set and display various process parameters, and the electric control system has advanced technology, convenient operation and reliable operation.
