Description

A cut mould fast for producing automobile parts

Technical Field

The utility model belongs to the technical field of machinery basic part and manufacturing, more specifically say, relate to a quick cutting die for producing automobile parts.

Background

In the field of automobile part production, blanking is one of widely used processing methods, and is commonly used in processes such as cutting and trimming of metal parts. The blanking is to make the plate produce shearing deformation and separation along a certain contour line by using the cutting edge of the die. The proportion of blanking in the stamping production is the largest. During the blanking process, the sheet material itself does not undergo plastic deformation except for the metal near the shearing contour line, so that the part blanked from the flat plate is still in a planar shape. During blanking, the quality of the cutting die has direct influence on the product quality, the production efficiency and the cost. The technology accumulation in the field of cutting dies in China is relatively weak, the starting is late, and certain gap still exists between the die design and the increasingly diversified high-standard use requirements.
