Detailed Description

The invention will be further described with reference to the following drawings and examples:

referring to fig. 1 to 3, the trimming and punching die for the fuel tank shell comprises:

the oil tank punching die comprises a lower die holder 1, wherein a lower die head 2 is fixed on the lower die holder 1, a first profiling surface 3 matched with the inner wall of an oil tank is arranged on the lower die head 2, a first blanking hole 4 and a second blanking hole 5 penetrating through the lower die holder 1 are formed in the lower die head 2, a first knife holder 6 is fixed on the left side of the lower die head 2, a second knife holder 7 is fixed on the right side of the lower die head 2, a third knife holder 8 is fixed on the front side of the lower die head 2, a first trimming punch 9 is fixed on the first knife holder 6, a second trimming punch 10 is fixed on the second knife holder 7, a third trimming punch 11 is fixed on the third knife holder 8, and a cutting edge is arranged at the edge of the lower die head 2;

the stamping die comprises an upper die base, wherein an upper die head is fixed on the upper die base, an upper die cavity is formed in the upper die head, a first stamping head 18 and a second stamping head 19 are fixed in the upper die cavity, a stamping core cavity 20 is movably connected in the upper die cavity through a compression spring, and a second profiling surface 12 matched with the outer wall of the oil tank is arranged in the stamping core cavity 20.

The utility model discloses the process is as follows when using, the oil tank casing carries out the punching press of profile after the last process, the edge of oil tank casing can have a waste material that needs to amputate, carry out the side cut of waste material and the action of punching a hole of oil tank casing through this side cut-out press, when concrete, place the oil tank casing on the first profile surface 3 of lower die head 2, afterwards, the upper die base drives the upper die head and carries out the punching press downwards, because first punching press head 18 and second punching press head 19 are fixed in the upper die cavity, punching press core cavity 20 is movable again simultaneously, so can punch out two special-shaped holes of oil tank casing through first punching press head 18 and second punching press head 19, simultaneously, the waste material of special-shaped hole department drops from first blanking hole 4 and second blanking hole 5, in addition, the blade dislocation that punching press core cavity 20 and the right angle face at lower die head 2 edge formed moves, the waste material at the edge of the oil tank shell is cut off, and then is driven by the upper die base to automatically move downwards, and finally, the annular waste material is cut into a plurality of parts through the three edge punching knives, so that the waste material is conveniently collected after falling.
