3. Structure overview

3.1 main machine: the winding drum installed on the rack is rotated by the AC motor through the gear reducer, and the speed of the motor is controlled by the AC converter to realize stepless speed regulation.

3.2 take-up trolley: the take-up trolley is equipped with a fall off device and a guide rail to let the trolley in and out.

3.3 electric control system: it is composed of AC frequency converter, contactor, operation panel, etc. This system uses AC frequency converter to control the current asynchronous motor. By changing the frequency of three-phase AC motor input power, the frequency converter makes the AC motor realize stepless speed regulation. It has good speed regulation characteristics, wide range, full protection function, small volume, light weight, simple structure, convenient installation and maintenance.

3.4 pneumatic system: it is composed of air cylinder, solenoid valve, air source triplet, etc. the system is controlled by the solenoid valve to compress the wire rod on the drum by the wire pressing roller on the air cylinder, so as to get off the line smoothly.

4. Process description

4.1 positioning of take-up trolley: jog the forward and backward buttons, and make the trolley in the middle position by pneumatic.

4.2 threading: the wire enters the drawing die box through the guide roller and straightening device and passes through the drawing die. The head of the wire is clamped by the chain and then pulled to the drum by inching.

4.3 wire drawing and winding up: start up after threading, gradually adjust the running speed to the required speed, then the wire can be wound up normally, and press the wire rod with the wire pressing roller.

4.4 stop the wire drawing machine and take-up trolley motor and start the air cylinder to automatically pull the trolley to replace the wire rack after one plate of material is collected.
