[0055] Start the fan 6. The output end of the fan 6 sucks out the waste in the waste trough through the telescopic pipe 7 and the suction hood 8 and sends it to the waste collection bin 5, eliminating the need for manual cleaning, which is more convenient, realizing the rapid cleaning of waste and improving the processing efficiency.

[0056] The punching die for the engine sound insulation part holes also includes: two hydraulic cylinders 4; the output ends of the two hydraulic cylinders 4 are fixedly connected to the upper end surface of the punching die 3 for pushing the punching die 3 to move vertically. The model of the hydraulic cylinder 4 is selected according to actual needs as long as it meets the working conditions.

[0057] In this embodiment, as Figure 2 and Figure 4 shown, the adjusting device includes: a worm gear 9, a support plate 12, a worm 10, a first motor 11, a rotating member 13, two moving rods 14 and two connecting members 15.

The cylindrical pin is arranged in the sliding groove and is slidably connected to the rotating member 13 through the sliding groove.

[0059] When the rotating member 13 rotates, it will make the two moving rods 14 move towards the middle or towards the outside simultaneously through the sliding between the sliding groove and the cylindrical pin.

[0060] The surface of each connecting member 15 is fixedly connected to the end of the moving rod 14 away from the worm gear 9, and the bottom end of the connecting member 15 is fixedly connected to the telescopic pipe 7. The moving rod 14 drives the connecting member 15 to move, and the connecting member 15 will cause the telescopic pipe 7 to extend or contract.

[0061] When it is necessary to adjust the cleaning position, start the first motor 11. The output end of the first motor 11 drives the worm 10 to rotate; the worm 10 simultaneously drives the worm wheel 9 to rotate slowly; the worm wheel 9 drives the rotating member 13 to rotate synchronously under the support of the support plate 12; the rotating member 13 will move the two groups of moving rods 14 towards the middle simultaneously through the sliding between the chute and the cylindrical pin; the moving rod 14 drives the connecting member 15 to move; the connecting member 15 will extend the telescopic tube 7, so that the two groups of suction covers 8 move towards the middle simultaneously, changing the cleaning position and making the cleaning more thorough.

[0062] The punching die for the holes of the engine sound insulation part further includes: a support frame 2; the support frame 2 is composed of a top plate and two groups of vertical plates. The tops of the two groups of vertical plates are fixedly connected to the top plate. The top plate is arranged below the waste collection box 5 and is fixedly connected to the waste collection box 5 respectively, for supporting the waste collection box 5.

[0063] After the collection of the waste is completed, due to the large volume of the waste collection box 5, it is inconvenient to move.

[0064] To solve the above problems, this embodiment proposes an implementation manner. The punching die for the holes of the engine sound insulation part further includes: a cleaning auxiliary device; the cleaning auxiliary device is arranged in the space for taking out the waste located inside the waste collection box 5.

[0065] In this embodiment, as Figure 2 shown, the cleaning auxiliary device includes: a collection plate 16, a pulling member 17 and two groups of shielding plates 18.

[0066] Specifically, the collection plate 16 is arranged inside the space at the lower part; the pulling member 17 is arranged above the collection plate 16, and the bottom end of the pulling member 17 is fixedly connected to the collection plate 16; the two groups of shielding plates 18 are both arranged above the waste collection box 5 and are in contact with the waste collection box 5, for preventing the waste from flying out of the waste collection box 5. Notches are opened at the contact positions of the two groups of shielding plates 18 and the pulling member 17, and the size of the notches is slightly larger than the size of the pulling member 17.

[0067] When it is necessary to clean the waste, push the two groups of shielding plates 18 outwards; then pull the pulling member 17 upwards. The pulling member 17 drives the collection plate 16 to move, and the collection plate 16 will take out the waste, and then the cleaning can be carried out.

[0068] Since the punching positions of different raw materials are different, and the existing support device cannot move, the position occupied by the support device cannot be punched.

[0069] To solve the above problems, this embodiment proposes an implementation manner. The punching die for the holes of the engine sound insulation part further includes: a support device; the support device is arranged inside the workbench 1 for supporting the raw materials.

[0070] In this embodiment, asFigure 2 and Figure 5 As shown in Figure 5 , the supporting device includes: a bevel gear set 19, a second motor 20, two groups of grooved drums 21, two groups of sliders 22, two groups of cross plates 23 and two groups of support blocks 24.

[0071] Among them, the bevel gear set 19 is composed of a first bevel gear and two groups of second bevel gears. The edges of the first bevel gear are respectively meshed and connected with the two groups of second bevel gears, and the rotation directions of the two groups of second bevel gears are opposite; the output end of the second motor 20 is fixedly connected to the axis of the first bevel gear. The model of the second motor 20 is selected according to actual needs as long as it meets the working conditions; each group of grooved drums 21 is coaxially arranged with the second bevel gear, and the surface of the grooved drum 21 is provided with an inclined slide rail connected end to end; each group of sliders 22 is arranged inside the inclined slide rail and is slidably connected with the grooved drum 21 through the inclined slide rail.

[0073] Each group of cross plates 23 is arranged above the slider 22, and one end of the cross plate 23 is fixedly connected to the slider 22; each group of support blocks 24 is fixedly connected to the other end of the cross plate 23, and the slider 22 drives the cross plate 23 to move horizontally.

[0074] The cross plate 23 penetrates through the corresponding position of the workbench 1 and is slidably connected with the workbench 1.

[0075] Working principle:

[0076] When the punching die for the sound insulation part of the engine is in use, first, the user adjusts the position of the supporting device; starts the second motor 20, and the output end of the second motor 20 drives the first bevel gear to rotate; the first bevel gear drives the two groups of second bevel gears to rotate at the same time; the second bevel gear drives the grooved drum 21 to rotate synchronously; the grooved drum 21 will make the slider 22 move horizontally through the sliding between the inclined slide rail and the slider 22; the slider 22 drives the support block 24 to move through the cross plate 23; thereby changing the position of the support.

[0077] At this time, the raw material is placed on the supporting device, and the positions of each punching column are adjusted; then the hydraulic cylinder 4 is adjusted, and the output end of the hydraulic cylinder 4 pushes the punching die 3 downward; the punching die 3 punches the raw material, and after punching, the product is taken off.

[0078] After that, start the first motor 11, and the output end of the first motor 11 drives the worm 10 to rotate; the worm 10 simultaneously drives the worm wheel 9 to rotate slowly; the worm wheel 9 drives the rotating member 13 to rotate synchronously under the support of the support plate 12; the rotating member 13 will move the two groups of moving rods 14 towards the middle simultaneously through the sliding between the chute and the cylindrical pin; the moving rods 14 drive the connecting member 15 to move; the connecting member 15 will extend the telescopic tube 7, so that the two groups of suction covers 8 move towards the middle simultaneously, changing the cleaning position and making the cleaning more thorough.

[0079] Meanwhile, start the fan 6, and the output end of the fan 6 sucks out the waste in the waste chute through the telescopic tube 7 and the suction cover 8, and sends it to the waste collection box 5, eliminating the need for manual cleaning, which is more convenient, realizing the rapid cleaning of waste and improving the processing efficiency.

[0080] Subsequently, push the two groups of shielding plates 18 outwards; then pull the pulling member 17 upwards, and the pulling member 17 drives the collection plate 16 to move, and the collection plate 16 will carry out the waste, which can be centrally cleaned, completing the use of this device.
