Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 5, in order to illustrate an embodiment of the present invention, the trench cover progressive stamping die of the present embodiment includes an upper die 1 and a lower die 2, and an upper die core 3 and a lower die core 4 are respectively disposed in the upper die 1 and the lower die 2; the upper mold core 3 comprises a punching plate 301, a through groove 302 is arranged in the center of the punching plate 301, a punch mounting block 304 is arranged in the through groove 302, a first through hole 305 is arranged on the punch mounting block 304, punches 306 are arranged in the first through holes 305, and punching grooves 303 are arranged on the punching plate 301 and positioned on two sides of the through groove 302; the lower mold core 4 comprises an installation block 401 corresponding to the stamping plate 301, a salient point 402 corresponding to the stamping groove 303 is arranged on the installation block 401, the lower mold core 4 further comprises a position yielding block 403 corresponding to the stamping head installation block 304, and a second through hole 404 corresponding to the first through hole 305 is arranged on the position yielding block 403.

In the process of stamping, the upper die 1 is installed on a press, a plate is placed on the lower die core 4, and when the upper die 1 presses down the plate, the plate moves along with the plate. Through the combined action of the punch mounting block 304 and the abdicating block 403, a groove is punched in the plate, through the matched use of the punch 306 and the second through hole 404, a hole in the shape of the punch 306 can be punched at the groove, and through the matched use of the punching groove 303 and the salient point 402, an upward raised bump can be punched in the plate.
