Basic knowledge of Foshan screw mould

Foshan screw mould -- as the name implies, it is the mould for making screws, which is generally divided into two categories: 1. The head mould (main mould, thread mould, scissors, up punch, down punch, punching sleeve, sleeve, etc.); 2. The thread rubbing plate (mechanical thread rubbing plate, self tapping thread rubbing plate, etc.).

Foshan screw mold work characteristics is that the screw mold first uses the head mold to type the screw head, and then the thread is rubbed out by the thread rubbing board, that is, the tooth plate!

In Foshan screw mould, the material selection of the starting die is very important. The main service life depends on the quality of tungsten steel inside. The authentic tungsten steel can effectively guarantee the service life. The rubbing plate should have high hardness, wear resistance, sufficient strength, certain impact force and fatigue resistance. The hardness of the working part is 59-2hrc. If it is more than 62Hrc, it is easy to crack teeth,
