Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a punching device for muffler plate production in automobiles, which can solve the technical problem that the device punches through punches on the pressure plate and the spacing between the punches on the pressure plate is fixed and cannot be adjusted, thus limiting the application range of the device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a punching device for a muffler plate in automobile muffler production, comprising a workbench, a bracket fixedly connected to the upper end of the workbench, a hydraulic rod provided at the upper end of the bracket, a placement frame fixedly connected to the output end of the hydraulic rod, a pair of first through holes at the lower end of the placement frame, a pair of limiting holes at the upper end of the placement frame, a pair of connecting plates slidably disposed inside the placement frame, a punching head fixedly connected to the lower end of the connecting plate, one end of the punching head penetrating through the first through hole and extending to the outside of the placement frame, an L-shaped plate fixedly connected to the upper end of the connecting plate, the L-shaped plate penetrating through the limiting hole and extending to the outside of the placement frame, a bolt threadedly connected to the L-shaped plate, a limiting block fixedly connected to one end of the bolt, and multiple limiting grooves evenly spaced on the placement frame, a pointer fixedly connected to one side of the L-shaped plate, and a scale mark affixed to the upper end of the placement frame.

[0006] In a preferred embodiment of this invention, the width of the first through hole is larger than the width of the limiting hole.

[0007] As a preferred embodiment of this utility model, a pair of fixing plates are fixedly connected to the upper end of the workbench.

[0008] As a preferred embodiment of this utility model, an electric telescopic rod is provided on the fixed plate, and a clamping plate is fixedly connected to the output end of the electric telescopic rod. An anti-slip pad is provided on one side of the clamping plate.

[0010] As a preferred embodiment of this utility model, a collection box is placed on the ground below the workbench.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the bolt, the bolt drives the limiting block to move upward until the limiting block leaves the limiting groove, thus no longer fixing the L-shaped plate and the connecting plate. This allows the two connecting plates inside the placement frame to move. The movement of the connecting plates then drives the punching head to start. At the same time, with the cooperation of the pointer and scale markings on the L-shaped plate, the distance between the punching heads can be adjusted more precisely, thus improving the range of applications of the device. After the distance between the punching heads is adjusted, the bolt is rotated in the opposite direction again, causing the bolt to drive the limiting block to move downward until the limiting block is inserted back into the limiting groove, thus effectively fixing the L-shaped plate and the connecting plate, and thus limiting and fixing the punching head.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0018] Example

[0019] Please refer to Figures 1-3 As shown, this utility model provides a punching device for a muffler plate in automobile muffler production. The width of the first through hole 5 is larger than the width of the limiting hole 6. A pair of fixing plates 15 are fixedly connected to the upper end of the workbench 1. An electric telescopic rod 16 is provided on the fixing plate 15. A clamping plate 17 is fixedly connected to the output end of the electric telescopic rod 16. An anti-slip pad 18 is provided on one side of the clamping plate 17. The anti-slip pad 18 can better clamp and fix the muffler plate. A second through hole 19 is opened on the workbench 1. A collection box 20 is placed on the ground below the workbench 1.

[0020] When in use, place the muffler plate on the upper end of the workbench 1 and start the two electric telescopic rods 16. The two electric telescopic rods 16 can drive the clamping plates 17 to move towards each other until the two clamping plates 17 are clamped and fixed with the muffler plate. The anti-slip pads 18 on the clamping plates 17 can better clamp and fix the muffler plate. In addition, the waste generated during the punching process can fall into the collection box 20 through the second through hole 19 and be collected in a centralized manner.

[0021] As a further implementation of this embodiment, such as Figures 1-4 As shown, a bracket 2 is fixedly connected to the upper end of the workbench 1. A hydraulic rod 3 is installed on the upper end of the bracket 2. A placement frame 4 is fixedly connected to the output end of the hydraulic rod 3. A punch head 8 is fixedly connected to the center of the lower end of the placement frame 4. A pair of first through holes 5 are opened at the lower end of the placement frame 4. A pair of limiting holes 6 are opened at the upper end of the placement frame 4. A pair of connecting plates 7 are slidably arranged inside the placement frame 4. The punch head 8 is fixedly connected to the lower end of the connecting plate 7. One end of the punch head 8 passes through the first through hole 5 and extends to the outside of the placement frame 4. An L-shaped plate 9 is fixedly connected to the upper end of the connecting plate 7. The L-shaped plate 9 passes through the limiting hole 6 and extends to the outside of the placement frame 4. The limiting hole 6 can limit the L-shaped plate 9 to a certain extent. A bolt 10 is threadedly connected to the L-shaped plate 9. One end of the bolt 10 is fixedly connected to a limiting block 11. Multiple limiting grooves 12 are evenly spaced on the placement frame 4. A pointer 13 is fixedly connected to one side of the L-shaped plate 9. The pointer 13 and the stamping head 8 are located on the same vertical plane. A scale mark 14 is affixed to the upper end of the placement frame 4.

[0022] In use, by rotating the bolt 10, the bolt 10 moves the limiting block 11 upward until the limiting block 11 leaves the limiting groove 12, thus no longer fixing the L-shaped plate 9 and the connecting plate 7. This allows the two connecting plates 7 inside the placement frame 4 to move. The movement of the connecting plates 7 in turn moves the punching head 8. Simultaneously, with the cooperation of the pointer 13 and the scale mark 14 on the L-shaped plate 9, the distance between the punching heads 8 can be adjusted more precisely, thus improving the range of applications of the device. After the distance between the punching heads 8 is adjusted, the bolt 10 is rotated in the opposite direction, causing the bolt 10 to move the limiting block 11 downward until the limiting block 11 is inserted back into the limiting groove 12, thus effectively fixing the L-shaped plate 9 and the connecting plate 7, and thus limiting and fixing the punching head 8.

[0023] Specific working principle: During use, the silencing plate is placed on the upper end of the workbench 1, and the two electric telescopic rods 16 are activated. The two electric telescopic rods 16 can drive the clamping plates 17 to move towards each other until the two clamping plates 17 are clamped and fixed to the silencing plate. The anti-slip pads 18 on the clamping plates 17 can better clamp and fix the silencing plate. Then, adjust the distance between the punching heads 8 as needed. First, by rotating the bolt 10, the bolt 10 drives the limiting block 11 to move upward until the limiting block 11 leaves the limiting groove 12, thus no longer fixing the L-shaped plate 9 and the connecting plate 7. This allows the two connecting plates 7 in the placement frame 4 to move. The movement of the connecting plates 7 in turn drives the punching heads 8 to move. At the same time, the pointer 13 and the scale mark 14 on the L-shaped plate 9 work together to move the L-shaped plate 9. With the cooperation of the two devices, the spacing between the punching heads 8 can be adjusted more precisely, thereby improving the range of applications of the device. After the spacing between the punching heads 8 is adjusted, the bolt 10 is rotated in the opposite direction again, causing the bolt 10 to move the limiting block 11 downward until the limiting block 11 is inserted into the limiting groove 12 again, thereby fixing the L-shaped plate 9 and the connecting plate 7, and limiting and fixing the punching head 8. Finally, the hydraulic rod 3 is activated, causing the hydraulic rod 3 to move the placement frame 4 and the punching head 8 downward until the punching head 8 punches the soundproof plate at the top of the workbench 1. The waste generated during the punching process can fall into the collection box 20 through the second through hole 19 and be collected.
