Forming and coiling die for cover

Abstract

The invention relates to a forming and coiling die for a cover, the die has a stamping state and a coiling state, is used for stamping a sheet material into the cover and coiling the edge of the cover, and comprises an upper die and a lower die, the upper die comprises a coiling groove and a stamping head capable of moving up and down relative to the coiling groove, and the coiling groove surrounds the stamping head; the lower die comprises a coiling guide part and a stamping matching part capable of moving up and down relative to the coiling guide part, and the coiling guide part surrounds the stamping matching part and is in a stamping state; the stamping head and the stamping matching part keep pressing the cover tightly, and the stamping head and the stamping matching part move upwards at the same time to enable the edge of the cover to move into the coiling groove; a coiling groove completes coiling on a cover edge, stamping forming and coiling on a formed cover are achieved in one device, the two technologies are fused, stamping and transferring mechanisms and manpower are saved, and the production speed is increased; the two processes are carried out continuously without redundant steps.

Description

technical field [0001] The invention relates to the field of can-making and barrel-making equipment, in particular to a molding and winding mold for lids. Background technique [0002] In the prior art, for the preparation of cans, barrels, etc., especially for materials such as metals that need to be manufactured by stamping, it is usually necessary to manufacture the can body, barrel body, etc., and the lid separately, so the lid has its own independent production line. In the production process of the cover that needs to be produced by stamping, it is necessary to cut the sheet material to a suitable size, then stamp the cover, and then coil the edge of the cover, which requires multiple equipment. And it needs to be transferred between multiple devices, the production process is long and the production speed is slow. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention an...
