[0044] AsFigure 7 and Figure 8 As shown in Figure 8 , as a specific solution, the compaction assembly includes: a compaction cylinder 32, a rotary cover 35, a pressure plate 36, and a hydraulic cylinder 34. The top of the compaction cylinder 32 is fixedly connected to the bottom end of the connection cylinder 31, and the connection cylinder 31 is installed in communication with the compaction cylinder 32. A hydraulic cylinder 34 is fixedly installed on the outer wall of one end of the compaction cylinder 32. The output shaft end of the hydraulic cylinder 34 is fixedly installed with a pressure plate 36. The pressure plate 36 is connected to the inside of the compaction cylinder 32 with a clearance fit.

The pressure plate 36 moves to the left, so that the remaining material passes through the pressure plate 36 and the rotary cover 35 for compaction, and the scattered remaining material is compacted into a whole. After compaction, the second motor 37 is driven to rotate the connection shaft 40, thereby driving the rotary cover 35 to rotate. Specifically, it rotates 180°, so that the rotary cover 35 stops blocking the opening of the compaction cylinder 32. Then, driven by the hydraulic cylinder 34, the compacted remaining material is pushed out by the pressure plate 36, which is convenient for the remaining material to form a whole and is convenient for recycling.

[0045] As Figure 2 shown in Figure 2 , as a specific solution, the pressure seat includes: a connecting plate 11, a pressing plate 12, a compression spring 17, and a guide rod 15.

The pressing plate 12 contacts the top of the automobile bumper and presses downward, compressing the compression spring 17, so that the compression spring 17 generates elastic deformation. The elastic force generated by the compression deformation of the compression spring 17 provides pressure for the pressing plate 12 to realize clamping in the up and down positions.

[0046] As Figure 4 、 Figure 5 、 Figure 6As shown in the figure, as a specific solution, the punching assembly includes: a protective case 22, a fixing block 23, a rotating shaft 24, a cam 25, a first motor 26, a worm 27, a worm gear 28, a pressing strip 14, a punching rod 18, and a return spring 19. The protective case 22 is arranged in a notch 13 opened on a connecting plate 11. Fixed blocks 23 are fixedly installed at both the front and rear ends of the protective case 22. The fixed blocks 23 are fixedly connected to the wall of the notch 13. A first motor 26 is fixedly installed on the outer wall of the protective case 22.

One end of the return spring 19 is fixedly connected to the bottom of the pressing strip 14, and the other end of the return spring 19 is fixedly connected to the top of the pressing plate 12. Driven by the first motor 26, the worm 27 rotates. Through the meshing transmission between the worm 27 and the worm gear 28, the rotating shaft 24 is driven to rotate. During rotation, due to the irregular structure of the cam 25 up and down, the pressing strip 14 can be pressed downwards, so that the pressing strip 14 and the punching rod 18 move downward together, and at the same time, the return spring 19 is compressed. The punching rod 18 punches the automobile bumper. After punching, the elastic force of the return spring 19 provides reset for the pressing strip 14, so that the pressing strip 14 and the punching rod 18 are reset together. When not punching, the punching rod 18 does not extend from the bottom of the pressing plate 12.

[0047] As Figure 10 As shown in the figure, a control cabinet 10 is fixedly installed at the top of the frame 1. The control cabinet 10 is electrically connected to a clamping cylinder 4, a pressing cylinder 8, a first motor 26, a hydraulic cylinder 34, a second motor 37, and a third motor 41.

Among them, the control cabinet 10 has a single-chip microcomputer controller or adopts PLC control, and has control buttons and a touch screen on the outside to realize the control of the whole machine.

[0048] Usage method: When the entire automobile bumper punching machine is in use, the automobile bumper is placed in the positioning groove 5. Driven by the clamping cylinder 4, the pressing block 21 presses the front and rear positions of the automobile bumper to achieve front and rear clamping. At the same time, the pressing seat is driven to move downward by the downward pressing cylinder 8. The pressing plate 12 contacts the top of the automobile bumper and presses downward to compress the compression spring 17, causing the compression spring 17 to undergo elastic deformation. The elastic force generated by the compression deformation of the compression spring 17 provides pressure for the pressing plate 12 to achieve clamping in the up and down positions, thereby realizing clamping at the four positions of the upper, lower, front, and rear of the automobile bumper, and the overall clamping effect is good;

[0049] After clamping and positioning, driven by the first motor 26, the worm 27 rotates. Through the meshing transmission between the worm 27 and the worm gear 28, the rotating shaft 24 is driven to rotate. During rotation, due to the irregular up and down structure of the cam 25, the pressing strip 14 can be pressed downward, causing the pressing strip 14 and the punching rod 18 to move downward together, and at the same time compressing the return spring 19. The punching rod 18 punches the automobile bumper. After punching, the return spring 19 provides a return force for the pressing strip 14, causing the pressing strip 14 and the punching rod 18 to return together. When not punching, the punching rod 18 does not extend from the bottom of the pressing plate 12. After punching, the downward pressing cylinder 8 and the clamping cylinder 4 both return, stopping the clamping of all parts around the automobile bumper, and it is taken off manually, and the punching process of the next automobile bumper workpiece can be carried out;

[0050] The waste material generated by punching enters the conveying pipe 9 through the blanking groove 6. Driven by the third motor 41, the rotating rod 29 and the spiral conveying blade 30 rotate together, thereby providing transportation for the waste material, causing the waste material to enter the compaction cylinder 32 through the connecting cylinder 31. When a certain amount of waste material is collected, the pressing disc 36 is further driven to move by the hydraulic cylinder 34. The pressing disc 36 moves to the left, causing the waste material to be compacted through the pressing disc 36 and the rotating cover 35, making the scattered waste material compacted into a whole;

[0051] After compaction, the connecting shaft 40 is driven to rotate by the second motor 37, thereby driving the rotating cover 35 to rotate. Specifically, it rotates 180°, causing the rotating cover 35 to stop blocking the opening of the compaction cylinder 32. Then, driven by the hydraulic cylinder 34, the compacted waste material is pushed out by the pressing disc 36, facilitating the waste material to form a whole and facilitating recycling.

[0052] The above are only specific embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
