Summary of the invention

[0004] In order to solve the problems of low efficiency of step-by-step operation, high labor intensity, high labor cost, poor product consistency, low yield rate, high mold cost, and inability to effectively meet production requirements in the above-mentioned prior art, the present invention adopts the following technical solution: The present invention provides a composite forming die for a motorcycle oil tank upper cover, comprising an upper die seat, a stripper plate, a trimming die, an upper side hole punch, a lower side hole punch, a forming convex strip group, an upper flanging punch, a lower flanging punch, a plurality of small hole punches, a lower die seat, a trimming concave-convex die, an upper flanging concave-convex die and a lower flanging die, wherein the stripper plate is connected to the bottom of the upper die seat by a stripper spring, the trimming die is arranged at the bottom of the stripper plate, and the upper side hole punch and the lower side hole punch are arranged on the right side of the trimming die in an upper and lower distribution. The upper flanging punch is arranged on the left side of the trimming die, the forming convex strip group and the lower flanging punch are arranged in the middle of the trimming die in an upper and lower distribution, the plurality of small hole punches are distributed on the outer circles of the upper flanging punch and the lower flanging punch, the trimming concave and convex mold is arranged on the lower die seat and corresponds to the trimming die, the upper flanging concave and convex mold is arranged on the left side inside the trimming concave and convex mold and corresponds to the upper flanging punch, and the lower flanging die is arranged at the lower middle part of the trimming concave and convex mold and corresponds to the lower flanging punch.

[0005] Preferably, the unloading plate is provided with four guide holes, the lower die base is provided with four guide posts, and the guide holes correspond to the guide posts one by one.

[0006] The beneficial effects of the present invention are that a set of molds can complete trimming, punching, upper and lower flanging, and two side punching in one mold closing, without the need for step-by-step processing, high operating efficiency, low labor intensity, low labor cost, good product consistency, high yield rate, low mold cost, and effectively meet production requirements.

[0010] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0011] See also Figure 1 A composite forming die for a motorcycle fuel tank upper cover, comprising an upper die base 1, a stripper plate 2, a trimming die 3, an upper hole punch 4, a lower hole punch 5, a forming convex strip group 6, an upper flanging punch 7, a lower flanging punch 8, a plurality of small hole punches 9, a lower die base 10, a trimming concave-convex die 11, an upper flanging concave-convex die 12 and a lower flanging die 13, wherein the stripper plate 2 is connected to the bottom of the upper die base 1 by a stripper spring, the trimming die 3 is arranged at the bottom of the stripper plate 2, the upper hole punch 4 and the lower hole punch 5 are arranged on the right side of the trimming die 3 according to an upper and lower distribution, and the upper flanging punch 7 is arranged on the trimming die 3, the forming convex strip group 6 and the lower flanging punch 8 are arranged in the middle of the trimming die 3 in an upper and lower distribution, the plurality of small hole punches 9 are arranged in the outer circles of the upper flanging punch 7 and the lower flanging punch 8, the trimming concave and convex die 11 is arranged on the lower die seat 10 and corresponds to the trimming die 3, the upper flanging concave and convex die 12 is arranged on the left side of the trimming concave and convex die 11 and corresponds to the upper flanging punch 7, the lower flanging die 13 is arranged at the lower middle part of the trimming concave and convex die 11 and corresponds to the lower flanging punch 8. During operation, the material is placed on the trimming concave and convex die, and the upper die seat moves downward until the die is closed. Figure 2 As shown, when the mold is closed, the trimming concave die and the trimming convex and concave die cooperate to cut out the outer shape. At the same time, the two side hole punches complete the side hole punching, the forming convex strip group will press out the convex strip, the upper flanging punch and the upper flanging concave and convex die cooperate to complete the upper flanging, the lower flanging punch and the lower flanging die cooperate to complete the lower flanging, and the small hole punch punches out all small holes. In this way, all shapes are completed by closing the mold at one time, even the irregular shape with curved surface, upper and lower flanging and oblique side punching can be completed at one time, which cannot be completed by traditional molds, and each requires a separate set of molds to complete them separately.

[0012] The unloading plate 2 is provided with four guide holes 21 , and the lower die base 10 is provided with four guide posts 101 . The guide holes correspond to the guide posts one by one, so that the mold closing is smoother and more accurate.

[0013] The beneficial effects of the present invention are that a set of molds can complete trimming, punching, upper and lower flanging, and two side punching in one mold closing, without the need for step-by-step processing, high operating efficiency, low labor intensity, low labor cost, good product consistency, high yield rate, low mold cost, and effectively meet production requirements.

[0014] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
