What are the Surface Pretreatment and Control Requirements of the Wire Drawing Machine?
The manufacturer of the inverted wire drawing machine introduced that the base of the wire drawing machine is very stable during the installation process so that the oscillation phenomenon can be effectively avoided. During the installation, it needs to be adjusted so that the drawing axis of the wire and the center of the die hole The line is symmetrical so that the stress effect of the wire and the drawing die can be made uniform.
During the drawing process of the wire drawing machine, it is necessary to avoid frequent start and stop, because the conflict formed by the tensile stress at the start of drawing is much larger than that during normal drawing, which will inevitably increase the wear of the die.
In addition, the wire used for the drawing must be pretreated: surface pretreatment and heat treatment.
In the process of surface pretreatment of the wire drawing machine, the wire rods with dirty surfaces and more impurities should be cleaned and dried before drawing.
For wires with more scale on the surface, they must be acid-thinned and dried before drawing.
For wires with peeling, pits, heavy skins, etc. on the surface, they must be ground by a grinder before drawing.
Heat treatment of wire drawing machine: For wires with excessive hardness or uneven hardness, they must first be annealed or tempered to reduce the hardness, and the wires should maintain good hardness uniformity before drawing a mechanical device.
It is rare for the control system to provide a very accurate and smooth line speed, and the wire drawing machine is one such devices, and its system has very high requirements for speed control.

The whole system of the wire drawing machine is relatively complicated, and the control equipment requires coordination among the various motors. The system is controlled by four servo motors, which can fully satisfy the real-time interaction between data.
In order to ensure the location of the side-to-side line of the trajectory according to the algorithm, it is required that the line of the line can be calculated quickly.
Make full use of the internal firmware function of the servo, and calculate by the driver itself, which greatly omits the total time calculated by the line position of the traditional wire drawing machine control system.
The commands are then sent to the drives, securing the lines to minimize delays through the controller.
