The Main Devices and System Components of the Wire Drawing Machine
The high-speed wire drawing machine is mainly used to draw metal wires of different specifications. The electrical transmission part is composed of a drafting motor, a take-up motor, and a wire arrangement motor.
Other auxiliary parts of the equipment include a swing bar (tension frame), positioning wheel, line dividing wheel, reciprocating wire arrangement rod, etc.
The drafting motor drives the drawing wheel to run, the four-stage drawing wheel is linked through the belt to realize metal stretching, and the take-up motor realizes winding.
Regarding the technical specifications and requirements of high-speed wire drawing machines:
- The equipment startup speed-up process needs to be synchronized;
- Keep the tension constant when the equipment is running;
- Synchronization is required when parking, without wire breakage or tension relaxation;
- Disconnection protection is required for equipment safety production;
- Inching threading function;
- The external button starts operation;
- Running speed display;
- The diameter ratio of the winding bye disc to the full disc is about 1:3;
- The full plate weight is about 50kg;
- The operating frequency is about 70HZ.
For different usage requirements, the system structure of the high-speed wire drawing machine needs to be carried out according to certain requirements.
Especially as components of electrical transmission equipment, they should be able to meet the usage requirements. For example, the drafting motor should be equipped with a corresponding frequency converter, and the winding motor needs to use a winding-specific frequency converter (with an external braking resistor).
In this way, during the operation of the high-speed wire drawing machine equipment, it uses the operation command and output frequency signal of the host machine as the operation command and frequency command of the slave machine to achieve synchronous operation.
When parking, the heavy disc is braked in the opposite direction to prevent wire breakage due to inertia, and the JOG function is used to achieve jogging work during threading operations.
In addition, with the operation of the high-speed wire drawing machine equipment, the pendulum output voltage signal is used as a feedback signal to achieve internal variable PID correction control.
And the unique winding curve of the Sanjing inverter series is used for speed prediction graphic operation to achieve constant linear speed winding, thereby meeting the actual requirements of the wire drawing process.
