Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a quick unloading mechanism for a metal stamping die. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

[0003] In the prior art, after the die is stamped, workers need to manually remove the stamped product from the die, which is time-consuming, labor-intensive, inefficient, and dangerous. Based on these problems, Chinese patent CN217166209U discloses a stamping die unloading mechanism, which drives the connecting shaft and the rotating plate to rotate by a driving motor. At this time, the rotating plate squeezes the movable disk, and the movable disk and the pushing column are pushed upward. At this time, the pushing column pushes the pushing plate upward, and the workpiece stamped inside the stamping groove can be unloaded. At the same time, under the action of the spring sleeve, the pushing column and the movable disk can be automatically pulled back to the initial position, so that they can be better used next time.

[0004] The unloading mechanism of the stamping die utilizes a push column and a push plate to push the material vertically upward. During the pushing process, the formed workpiece is easily pushed out of the stamping groove due to the upward thrust, which will not only cause the workpiece to fall, but also cause the workpiece to collide with the bottom surface of the upper template, thereby affecting the quality of the formed workpiece.
