[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] After massive search, it is found that the prior art publication number is CN211161481U, which discloses a continuous feeding stamping die, including a feeding part and a stamping part, the feeding part is arranged on one side of the stamping part, and the riveted parts are fed to the material strip, the feeding part includes a feeding upper die and a feeding lower die, the feeding upper die is provided with a punching punch and a plunger on the opposite side of the feeding lower die, the punching punch is arranged near the feed port, the plunger is arranged on the side opposite to the punching punch and the feed port, a slider is arranged below the plunger, the plunger is connected to the slider by an inclined contact, the plunger moves downward to make the slider move laterally, the slider is connected to the feeding lower die, and a connecting rod is arranged between the slider and the template of the feeding lower die. The utility model realizes automatic feeding, and when two or more products need to be stamped and riveted together, this mechanism can be used, and multiple strips of material are crossed in the same set of continuous dies to complete punching, forming, riveting, etc., without the need to use two or more feeders.
