Detailed description of the development momentum of the stamping die in Dalian

The sheet, strip, pipe and profile are exerted by the punch and die to produce plastic deformation or separation, thus forming the forming process of the required shape and size of the workpiece, and the workpiece is the stamping part. Generally, there will be iron scraps in the trimming of stamping dies, especially in the vicinity of the waste cutting tools. Iron scrap not only seriously affects the quality of products and the appearance of the mold cleanliness, but also reduces the production efficiency.

The application of high strength plate and unequal thickness laser welding plate is becoming more and more common. The application of high strength steel sheet hot stamping and large aluminum alloy sheet stamping technology in automobile production is increasing, because the speed of high speed punch press is increasing. The higher the distance between the integrated circuits is, the more precise the connectors are, and the smaller the volume, so the ultra precision machining is developing further.

As far as structure is concerned, it is necessary to ensure the convenience of feeding, fixing, discharging and cleaning waste. For small parts processing, operators, fingers, wrist or other parts of the body must be strictly prohibited to extend into the die area. For the processing of large parts, if the operator has to work in the mold, it is necessary to reduce the scope of the die into the mold as far as possible, to shorten the time of the body part to stay in the mold as far as possible, and should clear the scope of the dangerous zone of the mold, and provide the necessary protective measures and devices.

Dalian punching die can not satisfy the surface hardness after basic heat treatment, then heat treatment can be carried out again. The advantage of nitriding heat treatment is that it can form a thick layer of desalination layer on the surface of the mold to improve its hardness and wear resistance, and greatly prolong the service life of the stamping die.
