Insert assembly type automobile trimming-punching die

Abstract

The invention discloses an insert-assembled automobile trimming and punching die, comprising an upper die and a lower die, the upper die is arranged just above the lower die, an upper bottom plate is arranged at the end of the upper die away from the lower die, and the upper The mold and the upper bottom plate are integrally formed, and the upper bottom plate is used to fix the upper mold on the stamping power source. The end of the upper mold away from the upper bottom plate is provided with trimming inserts on both sides, and the trimming inserts are "Z" shaped. In addition, one end of the "Z" shape is fixedly connected with the upper mold through the first locking device, and the position corresponding to the trimming insert is provided with an insert groove and a mounting hole. In the present invention, the mold is split, so that the frequently worn parts such as trimming inserts, punch inserts, lower molds and stamping inserts can be disassembled and replaced. When the above parts are seriously worn, only the parts need to be replaced , the main body of the mold can continue to be used, which greatly reduces the loss of the mold and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an insert-assembled automobile trimming and punching mould. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. For a long time, the development of China's mold industry has been uneven in geographical distribution. The development of the southeastern coastal areas is faster than that of the central and western regions, and the development of the south is faster than that of the north. The most concentrated areas of mold production are in the Pearl River Delta and Yangtze River Delt...

AI Technical Summary

Problems solved by technology

[0003] When using ordinary molds to manufacture workpieces, a mold will be worn for a long time after long-term use. When the wear reaches a certain level, the parameters of workpieces manufactured by ordinary molds no longer meet the requirements. At this time, the mold can only be scrapped as a whole and cannot be used again, resulting in resource The waste increases the production cost, so we design a block-assembled automobile edge trimming punching die to solve the above problems
