Problems solved by technology

[0005] like figure 1 As shown, this type of structure is more structurally specific than normal stamping products. The product is fully enclosed, and the connection position of the product carrier has been closed and blocked at the other end. If you continue to use the up and down straight-through punching method, it will inevitably be formed. The product is bruised, and

Abstract

The invention discloses a movable cutting edge mechanism of a progressive stamping die. The movable cutting edge mechanism comprises a cutting punch, a middle die backing plate, a middle die plate, an upper die ejector pin, an upper restoring structure, a lower die ejector pin, a lower restoring structure, a sliding block and a sliding block seat. The movable cutting edge mechanism of the progressive stamping die can prevent a carrier from being frictionally deformed by finding a cutting point in the downward pressing process of a middle die plate through precise fitting between the sliding block and a pre-pressing ejector pin; and the sliding block can float up in an opened state, can diagonally move downwards in a closing process, can avoid the structure position of an already closed product and does not cause any problems such as collision and scratches to the product.

Description

technical field [0001] The invention relates to the field of electronic parts manufacturing equipment, in particular to a movable knife-edge mechanism of a stamping progressive die. Background technique [0002] With the continuous development of society, the pace of updating electronic products is accelerating, and supporting electronic components are gradually moving towards standardized and general-purpose mass production. Most product structures are finalized, space is limited, and stamping technology also requires continuous improvement to meet various product structures. [0003] According to the product structure needs to develop stamping dies that meet the application, and the standardized products have product size and structure due to their small size, so the stamping products are small in size and have strict requirements. The internal molding structure of the existing mold cannot meet the product design structure and precision requirements, resulting in a certain...
