The fabrication technology of metal stamping parts generally includes four types, namely: shearing, blanking, punching, and forming. No process is very easy to produce a large number of stamping scraps. The leftovers produced by stamping have characteristics that other machining processes do not have, which mainly include:
Relative dispersion of leftovers
The production mode of the metal stamping parts fabrication plant is multi-variety mass production. There are multiple punching machines in the stamping workshop, and the fabrication procedures of each punching machine are different. Basically, there is no process for automobile stamping parts, and there will be product scraps, which leads to The leftovers are relatively scattered.
Huge amount of leftovers
There are many kinds of stamping parts produced by metal stamping parts factories, and each product generally contains multiple processes, so the number of leftovers produced in the factory is very large. A small stamping factory can basically produce dozens of tons of stamping scraps a day.
Fast update of leftovers
There are various products to be processed in the stamping factory every day. When a product is produced, a kind of scrap is generated, and after the mold is replaced, the scrap of the product is another situation. The situation of the scraps of products in all general stamping plants is not the same.
Various shapes of leftovers
The fabrication technology of metal stamping parts is mainly composed of shearing, blanking, punching, forming, etc. Most of these processes will produce scraps, and the shapes of scraps of different process products are also different. The shape and size of scraps produced by different products and different processes are also different.
The composition of leftovers is complex
The materials used in metal stamping plants are mainly carbon steel, stainless steel, aluminum, copper and other metal materials, and all the scraps produced are also very complex. In addition, the thickness and mechanical properties of the same composition are also different; and the properties of the material will change due to the action of force after punching, and different pressures and different processes will change the material differently.
