What is a multi-station progressive die?
What is a multi-station progressive die? Multi-station progressive die is a kind of cold die. It is divided into several equidistant stations in a mold according to the stamping process of the parts to be processed, and a certain stamping process is set in each station to complete a certain part of the stamping work of the part. The material to be processed (strip or strip) is controlled by the automatic feeding mechanism, and the feeding distance is accurately controlled. After the punching of each station, the required stamping parts can be obtained. Generally speaking, multi-station progressive dies can continuously complete processes such as blanking, bending, and deep drawing. Therefore, no matter how complicated the shape of the stamping part is, and how many stamping processes are, it can be finished with a multi-station progressive die. Advantages of multi-station progressive die: 1. Multi-station progressive die is a multi-process die. In one mold, it can include multiple processes such as punching, bending, forming, and drawing. It has more than compound die Higher labor productivity, can also produce quite complex stamping parts; 2, multi-station progressive die operation is safe, because human hands do not enter the dangerous area; 3, multi-station progressive die design, the process can be scattered, no need to concentrate In one station, there is no 'minimum wall thickness' problem in composite molds. Therefore, the mold strength is relatively high and the service life is longer; 4, the multi-station progressive die is easy to automate, that is, it is easy to realize automatic feeding, automatic discharging, and automatic lamination; 5, the multi-station progressive die can be produced by a high-speed press , Because the workpieces and leftovers can directly leak down; 6. The use of multi-station progressive die can reduce the press and reduce the transportation of semi-finished products. The workshop area and warehouse area can be greatly reduced.
