Straight-cut wire drawing machine mold problem

Jan 17, 2019

During the operation of the straight-through wire drawing machine, not only the state of the equipment itself, but also the use of the mold should be considered. The first question that should be considered first is whether the choice of working cone angle is reasonable. If the angle we choose is unreasonable, then when the wire drawing device pulls the wire, its working cone angle will be negative or too small, which will bring certain negative effects.

 

Secondly, the mold used should maintain good stability during the operation of the straight-through wire drawing machine. If there is a break or a herringbone crack. The root of this problem is that the drawing process is not properly arranged. In the drawing process of the wire drawing machine, if the tensile stress used exceeds the strength it can withstand, it will cause cracks.

 

In addition, in order to ensure the working quality of the straight-through wire drawing machine equipment, attention should also be paid to the residual stress of the mold and the surface work hardening phenomenon. In fact, this situation is mainly caused by residual work. Under the action of residual work, the problem of material hardening will be more serious. If the situation is serious, it may even cause cracking and peeling of the surface of the wire. Therefore, if the process selection is not appropriate, it will eventually lead to a decline in the quality of the drawing machine equipment.www.chinawiredrawingmachine.com
