The wire drawing die can be used in the drawing production of various metal wires. It is a very important consumable die. The sizing area is the control part of the diameter of the die. The metal wire can get another size through this area. Reasonable sizing zone length can improve straightness, dimensional accuracy, surface roughness quality and mold life. The cost of the wire drawing die accounts for a very large proportion of the drawing cost. As a wire manufacturer, how to reduce costs, obtain stable and long-term stretching, accurate dimensions, and better surface quality is very important. But how to achieve it? Of course, it is difficult to achieve without high-quality drawing dies. Under certain conditions of the mold material, its hole structure is a key factor in determining the quality of the drawing die, because different drawing conditions require different hole structures to adapt to it. Only in this way can the life of the drawing die be prolonged and the life of the drawing die can be extended. Economic benefits. Therefore, the hole structure of the wire drawing die is very important to the wire drawing company. Today we will focus on understanding the important area sizing area of the drawing die.
The longer the sizing zone, the larger the contact area between the wire and the die hole, and the greater the frictional force. Therefore, the longer the sizing zone will increase the tensile force. However, the tensile stress must be greater than the tensile strength limit of the wire. The stretching process can only be carried out, otherwise it will cause wire breakage and make stretching impossible. Therefore, it is very important to find a suitable sizing zone length for drawing different grades of metal wire.
The sizing area must be straight and reasonable in length. If the sizing area is too long, the friction of the pull wire will increase, and the wire may be easily reduced or broken after being pulled out of the die hole. If the sizing area is too short, it is difficult to obtain a wire with stable shape, accurate size and good surface quality. Very quickly worn out.
