[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings.

[0024] As Figure 1 shown, an embodiment of the present application provides an automotive bumper punching machine, including a frame 1, a positioning tire mold 2 for fixing the bumper is arranged on the frame 1, and a punching mechanism 3 for punching the bumper on the positioning tire mold 2.

[0025] The punching mechanism 3 includes a fixed seat 31, an integrated fixed frame 32, a first cylinder 33, a punching assembly 34, a punching seat 36 and a hot air gun 35. The fixed seat 31 is installed inside the frame 1 and on one side of the positioning tire mold 2. The integrated fixed frame 32 is installed on the fixed seat 31. The first cylinder 33 is installed at the top of the integrated fixed frame 32. The driving end of the first cylinder 33 is connected to the punching assembly 34. The punching assembly 34 is slidably matched with the two side ends of the integrated fixed frame 32. The punching seat 36 is installed at the bottom of the integrated fixed frame 32. The punching seat 36 and the punching assembly 34 are on the same axis. When the bumper is fixed on the positioning tire mold, the punching seat 36 is located at the bottom of the bumper punching position, and the punching assembly 34 is located directly above the bumper punching position. The first cylinder 33 is used to drive the punching assembly 34 to move downward to cooperate with the punching seat 36 to punch the bumper.

[0026] The hot air gun 35 is installed on the side end of the integrated fixed frame 32, and the hot air gun 35 is used to heat and soften the bumper on the positioning tire mold 2.

[0027] Specifically, the support frames 341 of the punching assembly 34 are respectively slidably connected to the two side ends of the integrated fixing frame 32 through vertically arranged linear sliding rails. The first cylinder 33 drives the support frame 341 to drive the pre-pressing assembly 342 and the punch 343 to move up and down along the integrated fixing frame 32. The hot air gun 35 is installed at the side end of the integrated fixing frame 32, and the air outlet of the hot air gun 35 corresponds to the punching part of the bumper. Among them, the integrated fixing frame 32 is of a C-shaped structure, and the punching assembly 34 and the punching seat 36 installed on the integrated fixing frame 32 are on the same axis.

[0028] Place the bumper on the positioning die for fixing. The punching seat 36 is located at the bottom of the punching part of the bumper, and the punching assembly 34 is located directly above the punching part of the bumper. Then, the hot air gun 35 heats and softens the punching part of the bumper. Next, the first cylinder 33 drives the punching assembly 34 to move downward to cooperate with the punching seat 36 to punch the bumper. During the stamping process, the pre-pressing assembly 342 of the punching assembly 34 first presses the punching part of the bumper. After pressing, the punch 343 and the punching seat 36 cooperate to punch the softened punching part.

[0029] In the above structure, by setting an integrated fixing frame, the punching seat 36 and the punching assembly 34 are on the same axis, improving the accuracy of punching the bumper. Also, by setting the hot air gun 35 to heat and soften the punching part of the bumper, it not only improves the punching effect and efficiency but also ensures the integrity of the surface of the bumper after punching. This automobile bumper punching machine not only has high punching accuracy but also high punching efficiency, and can ensure the integrity of the outer surface of the bumper after punching.

[0030] As Figure 3 and Figure 4 shown, in one embodiment, the punching assembly 34 of the automobile bumper punching machine includes a support frame 341, a pre-pressing assembly 342, and a punch 343. The pre-pressing assembly 342 and the punch 343 are respectively connected to the bottom of the support frame 341. The pre-pressing assembly 342 is sleeved on the punch 343, and the bottom of the pre-pressing assembly 342 is located below the punch 343.

[0031] Specifically, when the bumper is fixed on the positioning die 2, the first cylinder 33 drives the support frame 341 to drive the pre-pressing assembly 342 and the punch 343 to move downward. During the movement, the pre-pressing assembly 342 first presses the outer ring of the punching part of the bumper. The first cylinder 33 continues to drive the support frame 341 to drive the pre-pressing assembly 342 and the punch 343 to move downward, so that the punch 343 cooperates with the punching seat 36 to punch the bumper. This setting facilitates the pre-pressing and punching operations of the bumper.

[0032] As Figure 3 and Figure 4As shown, in one embodiment, the pre-pressing assembly 342 of the automotive bumper punching machine includes an elastic assembly 001 and a pre-pressing head 002. One end of the elastic assembly 001 is connected to the support frame 341, and the other end of the elastic assembly 001 is connected to the pre-pressing head 002. The edge part of the pre-pressing head 002 is located below the punch 343.

[0033] Specifically, when the first cylinder 33 drives the support seat to drive the punching assembly 34 to move downward to punch the bumper, the pre-pressing head 002 first compresses the bumper. The first cylinder 33 continues to drive the support seat to move downward, so that the punch 343 punches the bumper. During punching, the pre-pressing head 002 compresses the elastic assembly 001, and the elastic assembly 001 plays a buffering role for the bumper and the punch 343. Among them, the elastic assembly 001 includes a pressing plate, four guide posts and four springs. One ends of the four guide posts respectively extend into the support seat and are slidably matched with the support seat. The other ends of the four guide posts are respectively connected to the four end corners of the pressing plate. The four springs are respectively sleeved on the guide posts. One end of the spring abuts against the support seat, and the other end of the spring abuts against the pressing plate. When the pressing plate is stressed, the pressing plate drives the four guide posts to compress the springs and move upward, and the compression of the four springs plays a role of pressing and buffering. This setting facilitates buffering the bumper and the punch 343 during punching, and can avoid damage to the bumper caused by excessive force of the punch 343.

[0034] As Figure 2 shown, in one embodiment, the positioning tire mold 2 of the automotive bumper punching machine includes a positioning frame 21, a plurality of profiling positioning blocks 22, a plurality of positioning plates 23 and a plurality of first suction cups 24. The positioning frame 21 is installed on the machine frame 1. The plurality of profiling positioning blocks 22 and the plurality of first suction cups 24 are respectively installed on one side end of the positioning frame 21, and the plurality of positioning plates 23 are respectively installed on the other side end of the positioning frame 21.

[0035] Specifically, one side end of the positioning frame 21 is provided with 7 profiling positioning blocks 22 and 2 first suction cups 24, and the other side end of the positioning frame 21 is provided with 3 positioning plates 23. Place the bumper on the 7 profiling positioning blocks 22 and the 2 first suction cups 24, and the 2 first suction cups 24 respectively suck and tighten the bumper, and the 3 positioning plates 23 position the side end of the bumper. This setting facilitates firmly fixing the bumper on the positioning tire mold 2.

[0036] As Figure 2 shown, in one embodiment, the plurality of profiling positioning blocks 22 of the automotive bumper punching machine are respectively provided with second suction cups 25 for sucking and tightening the bumper. Second suction cups 25 for sucking and tightening the bumper are arranged on all 7 profiling positioning blocks 22. This setting effectively strengthens the fixing effect on the bumper.

[0037] AsFigure 2 As shown, in one embodiment, a photoelectric sensor 26 for detecting whether a bumper is placed in place is provided on the positioning tire mold 2 of the automobile bumper punching machine. This setting facilitates detecting whether the positioning tire mold 2 has placed the bumper. If the bumper is not placed, the photoelectric sensor 26 promptly emits an alarm signal, facilitating timely handling by the staff.

[0038] As Figure 3 and Figure 4 As shown, in one embodiment, the integral fixing frame 32 of the automobile bumper punching machine is of a C-shaped structure. This C-shaped integral fixing frame 32 is conducive to the punching assembly 34 and the punching seat 36 being on the same axis.

[0039] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
