Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a clamping and feeding mechanism and a cold stamping progressive die. Background Art

[0002] The heat sink die is a high-precision cold stamping progressive die specially designed for the production of various heat sinks. At present, the movement of the material in the cold stamping progressive die is completed by a pulling system set at the rear end of the die. Its working principle is to use the feeding finger in the pulling system to probe into the flanging hole of the die to pull the material forward. After it is in place, it slides out of the flanging hole and moves backward to enter the next flanging hole. This cycle repeats to achieve continuous feeding. Therefore, the flanging hole must be completed before the pulling process. Therefore, when the material enters the die, it needs to be manually fed forward step by step until the formed material is sent to the pulling structure of the die. Only then can the material be automatically pulled. This has the problem of high labor intensity, and manual pulling can easily affect the stamping accuracy. Therefore, it is in urgent need of a solution. Summary of the Invention
