Description

Technical Field

[0001] The utility model relates to an adjustable upper die assembly for processing arc plates, belonging to the technical field of arc plate production. Background Art

[0002] In the existing stamping equipment, for arc-shaped plate parts or arc-shaped parts with arc lines, the stamping operation of the arc-shaped plate parts by the stamping equipment and the majority of the structural settings of the stamping equipment are relatively simple. By setting the convex die device of the stamping equipment as an arc structure, and the corresponding groove is also set as an arc structure, the cold stamping of the arc-shaped plate parts can be completed.

[0003] The patent with the patent number CN201820754000.4 discloses a cold stamping device for arc-shaped plate parts. It includes a stamping fixed seat at the bottom layer and a stamping propulsion device arranged above the stamping fixed seat; the propulsion head of the stamping propulsion device is arranged vertically downward, and an arc-shaped stamping convex die is also installed at the end of the propulsion head; and an arc-shaped concave die groove matching the shape of the arc-shaped stamping convex die is arranged on the stamping fixed seat.

[0004] The current technology has incomplete considerations and has the following drawbacks: When stamping arc plates, a stamping die needs to be used for stamping. However, in the specific production of a factory, after a certain type of arc plate has been produced for a period of time, its specification size may change, which requires opening a new die, undoubtedly increasing the production cost. Especially in the case where the accuracy requirements of the arc plate are not high, opening a new die with high accuracy is completely unnecessary.

[0005] To solve one of the above problems, there is an urgent need for an adjustable upper die assembly for processing arc plates. Content of the Utility Model
