Description

A continuous die capable of trimming, punching and drawing

technical field

The utility model relates to the technical field of moulds, in particular to a continuous die capable of shaping, trimming, punching and drawing.

Background technique

Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping machines, called cold stamping dies (commonly known as cold stamping dies); stamping is done at room temperature , A pressure processing method that uses a mold installed on a press to apply pressure to the material to cause separation or plastic deformation to obtain the required parts. 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.

There are many forms of stamping dies, and the stamping dies are also classified according to the nature of the work, the structure of the die, and the material of the die. (1) The die is a die that separates the material along the closed or open contour. Such as blanking die, punching die, cutting die, notch die, trimming die, cutting die, etc. (2) The bending die makes the sheet metal blank or other blanks bend and deform along a straight line (bending line), so as to obtain a die with a certain angle and shape of the workpiece. (3) The drawing die is a mold that makes the sheet blank into an open hollow part, or further changes the shape and size of the hollow part. (4) The forming mold is a mold that directly copies the rough or semi-finished workpiece according to the shape of the convex and concave molds in the figure, and the material itself only produces local plastic deformation. Such as bulging die, shrinking die, expanding die, undulating forming die, flanging die, shaping die, etc.

In the existing stamping dies for the production of auto parts, most of them use one stamping die to process only one process. If you need to process a product, you need to design the dies for each process. Not only does it take a lot of time and energy to design the dies, And after a long period of debugging, more manpower will be needed in the subsequent mass production, which will undoubtedly increase the cost of production.
