Bending and stamping die

Abstract

The invention discloses a bending and stamping die. The bending and stamping die comprises an upper die base, an upper padding plate, an upper clamp plate, an upper die plate, a lower die plate, a lower padding plate and a lower die base, wherein a bending punch is fixedly installed at the lower end of the upper die base, the bending punch sequentially passes through the upper padding plate and the upper clamp plate and then is matched with the upper die plate, a bending wall is arranged on one side of the bending punch, an insert core is arranged on the lower die plate, an enter groove is formed in one side of the insert core, the enter groove is aligned at the bending wall, a limiting block is arranged on the lower portion of the insert core, and the limiting block is fixedly installed on the lower die plate through a screw. The bending and stamping die is reasonable in structure and simple to operate, guarantees stability and reliability of bending, uses special structure of the bending punch, reduces bending resistance during the bending process, and reduces failure rate of work pieces, caused by abrasions during the bending process.

Description

technical field [0001] The invention relates to a stamping die, in particular to a bending stamping die. Background technique [0002] Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. The level of mold design and manufacturing technology is one of the important symbols to measure the level of a country's product manufacturing, which largely determines the quality, efficiency and new product development capabilities of products. The bending die is a kind of stamping die, which is used to form a tool for processing sheet metal. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. A tool used to make a blank int...

AI Technical Summary

Problems solved by technology

[0003] Most of the bending dies in the prior art use a cylindrical punch to stamp the sheet metal and press the outer wall of the punch to make it bend and shape. During the stamping process, because the outer wall of the punch has a large contact area with the workpiece, so There is a large bending resistance, which is easy to wear the surface of the workpiece and affect the performance of the workpiece
