Corner cutting die capable of adjusting corner cutting angle

Abstract

The invention relates to a corner cutting die capable of adjusting the corner cutting angle. The corner cutting die capable of adjusting the corner cutting angle comprises a corner cutting upper die,a base, guide rods, a corner cutting lower die, a rotary disc, corner cutting tools, a fixing plate, punching tools and a punching lower die. The base is located under the corner cutting upper die andis connected with the corner cutting upper die through the guide pillars. The corner cutting lower die is arranged above the base. The rotary disc is of a circular ring structure and is located at the bottom of the corner cutting upper die, and the lower end of the rotary disc is connected with the corner cutting tools. The fixing plate is fixed to the middle portion of the rotary disc, and the punching tools are arranged at the lower end of the fixing plate. The punching lower die is arranged on the base. The corner cutting die capable of adjusting the corner cutting angle has the beneficialeffects that the corner cutting angle can be adjusted, and in addition, the corner cutting process and the punching process can be conducted at the same time.

Description

technical field [0001] The invention relates to the field of moulds, in particular to a corner-cutting die which can adjust the corner-cutting angle. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products). Among them, 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. [0003] Wherein, the corner cutting and punching dies generally include an upper die and a lower die positioned below it. The bottom end of the upper mold is provided with a cutter. When in use, the base material is first placed on the lower die, and the upper die drives the cutter to go down to cut corners and punch holes for the base material. [0004] However, the existing corner-cutting molds cannot easily adjust the corner-cutting angle, and need t...

Problems solved by technology

However, the structural design of the existing corner-cutting punching die is not reasonable enough, especially the processing quality of the two processes cannot be satisfied at the same time, the qualified rate of the processed products is low, and the production efficiency is reduced, thereby indirectly increasing the production investment of the enterprise cost, and its unreasonable design also directly leads to the shortening of the service life of the mold
