Description

Technical Field

[0001] This application relates to the technical field of stamping dies, and particularly to double-layer stamping dies. Background Art

[0002] A stamping die is a special process equipment that processes materials (metals or non-metals) into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to the material using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] In the patent with the published authorization announcement number CN219817732U, this double-layer stamping die includes a box body. Two chutes are provided on the inner side wall of the box body. Sliders are slidably connected inside the two chutes. A sliding plate is fixedly connected to the side surfaces of the two sliders close to each other. A first upper die is fixedly connected to the bottom surface of the sliding plate. A first lower die is fixedly connected to the inner bottom wall of the box body. Two groups of springs are fixedly connected to the inner bottom wall of the box body. In this device, first, by providing an electric push rod, the electric push rod can drive the fixed plate to move downward, and the fixed plate drives the second upper die to move downward into the second lower die. Subsequently, by providing two connecting rods, the two connecting rods drive the sliding plate to move downward, and the sliding plate drives the first upper die to enter the first lower die. Then, by providing chutes and sliders, the chutes and sliders can drive the sliding plate to slide up and down in cooperation with the connecting rods and the fixed plate.

[0004] When the above device is implemented, it can only perform forming stamping on parts, and it is not convenient to perform punching operations on them synchronously after stamping. Therefore, it needs to be transferred to another device for punching operations. This approach is rather time-consuming and not conducive to popularization and use. Summary of the Utility Model
