Detailed Description

To make the objects, contents and advantages of the present utility model more apparent, the following detailed description of the present utility model will be given with reference to the accompanying drawings and examples.

The embodiment provides a fender stamping forming die, the structure of which is shown in fig. 1-3, and mainly comprises a female die 1, a male die 2, a female die fixing plate 3, a male die fixing plate 4, a positioning pin 5, a lower die plate 6 and an upper die plate 7.

The punch retainer 4 (structure shown in fig. 4) is positioned with the upper die plate 7 (structure shown in fig. 5) by pins and is assembled by screw fastening. The male die 2 is placed in a groove at the center of the male die fixing plate 4, is positioned with the upper die plate 7 through a pin, and is fastened and combined with the upper die plate 7 through a screw.

The die plate 3 (structure shown in fig. 6) is positioned with the lower die plate 6 (structure shown in fig. 7) by pins and is assembled by screw fastening. The female die 1 is placed in a groove at the center of the female die fixing plate 3, is positioned with the lower die plate 6 through pins, and is fastened and combined with the lower die plate 6 through screws. The locating pin 5 is fastened on the upper surface of the female die fixing plate 3 and is used for locating the product plate.

The structures of the male die 2 and the female die 1 are shown in fig. 8 and 9, respectively. According to the angle and specification of different strengthening ribs, the upper and lower surfaces of the male die 2 and the female die 1 are respectively provided with a forming protruding part and a groove part with different specifications, and the upper and lower surfaces of the male die 2 and the female die 1 are matched differently to realize the combination of the forming protruding part and the groove part with different specifications, so that the upper and lower molded surfaces are arranged in a staggered manner, and the stamping molded surfaces with different dislocation angles can be obtained.

The working principle of the stamping forming die is as follows: the upper die plate 7 and the lower die plate 6 are respectively fixed on the central positions of the upper table top and the lower table top of the machine tool, blank adding materials are placed on the die through a positioning plate and are positioned through a positioning pin 5, then a main shaft of the press machine is enabled to rotate through a clutch switch of the machine tool to drive a sliding block to drive the upper die part of the die to descend, and the die is molded under the action of the male die 2 and the female die 1. After the profiling is finished, the machine tool slide block drives the upper die part to ascend, and then the part is taken out from the die. When a fender of another specification is processed, the male die 2 and the female die 1 are exchanged, then the cut blank material is placed on a die, and after positioning, the product forming is completed under the action of the male die 2 and the female die 1.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
