Description

Technical Field

[0001] The utility model relates to the technical field related to hot stamping processing, in particular to hot stamping forming equipment for galvanized steel plates. Background Art

[0002] Hot stamping technology uses the principle of metal thermoplastic forming. After the metal sheet is heated, it is stamped and formed in one go through a stamping device. It is fast and has low forming difficulty.

[0003] When hot stamping galvanized steel sheets, metal impurities and metal surface debris will be deposited inside the molding cavity of the lower mold. The deposits accumulated inside the molding cavity will cause the lower side of the sheet to be deformed due to the squeezing of the deposits when the sheet is subsequently stamped, ultimately reducing the surface quality of the sheet. The deposits will also reduce the friction between the sheet and the lower side of the stamping device, further causing the sheet to shift and deform. It is inconvenient to completely clean the internal impurities and deposits out of the molding cavity during cleaning. Utility Model Content

The inner wall of the rotating groove is fixedly connected with a limit rod 5, and multiple support blocks 33 are slidably and interlacedly connected with the limit rod 5. The limit rod 5 limits the movement of the support block 33, so that the support block 33 can only slide along the limit rod 5 when moving; the clamping assembly 34 is arranged at the top of the workbench 1, and is used to clamp and flip the lower mold 31. Multiple pulleys 35 are fixedly installed on the bottom end of the support block 33. Multiple pulleys 35 are attached to the bottom end of the inner wall of the flipping groove, which are used to assist the support block 33 not to be easily displaced in the vertical direction, thereby avoiding deformation of the driving rod 32 and the limit rod 5 under stamping, and ensuring the normal use of the driving rod 32 and the limit rod 5.

[0036] Specifically, the clamping assembly 34 includes: a fixed plate 341, a threaded rod 342, a rotating plate 343, a clamping block 344 and a rotating block 345.
