The dust suction pump 17 is electrically connected to the PLC controller 21.

[0032] Among them, the dust suction pump 17 is used to collect miscellaneous dust and debris.

[0033] The end of the universal pipe 13 is fixedly connected to a dust suction head 5. The dust suction head 5 is located on the side of the placement plate 301. An adsorption plate 19 is fixedly connected inside the dust collection box 14. An exhaust port 15 is opened on the side of the dust collection box 14. A filter screen is fixedly connected inside the exhaust port 15.

[0034] Among them, the dust collection box 14 is convenient for collecting debris and miscellaneous dust. Since an adsorption plate 19 is also provided inside the dust collection box 14, the inhaled miscellaneous dust is adsorbed by the adsorption plate 19 to prevent it from floating around randomly.

[0035] The collection box 16 is located directly below the two holes 310. The collection box 16 is made of stainless steel.

[0036] Among them, the collection box 16 is used to collect the materials after punching. Since the collection box 16 is in contact with the bearing plate 7, the staff can easily take out the collection box 16 from the top of the bearing plate 7 and clean it.

[0037] An installation plate 12 is fixedly connected to the top of the processing table 1. A vertical plate 4 is fixedly connected to the top of the installation plate 12. The side of the vertical plate 4 is fixedly connected to the guide plate 201.

[0038] Among them, the vertical plate 4 is convenient for stably supporting the guide plate 201. Since the vertical plate 4 is fixedly connected to the processing table 1 through the installation plate 12, the installation plate 12 stably supports the vertical plate 4.

[0039] Support columns 8 are fixedly connected to the bottom of the bearing plate 7. The bottom of the support columns 8 is fixedly connected to a bottom plate 9. A storage box 11 is slidably connected to the top of the bottom plate 9.

[0043] When in operation, for a punching device for automotive plastic interior parts, first check if the device is in normal use. Move the device to a suitable working area through the moving wheels 10. Place the automotive interior part to be punched on the top of the placing plate 301, align the position to be punched with the hole 310. Start the hydraulic cylinder 210 through the PLC controller 21, and use the punch 212 to face the automotive interior part. Then place the fixing plate 302 on the top of the automotive interior part, rotate the adjusting bolt 303 to extend it into the threaded hole 305, thereby tightly abutting the fixing plate 302 against the automotive interior part. At the same time, an anti-slip pad 304 is provided at the bottom of the fixing plate 302 to improve stability and avoid the position movement of the automotive interior part during processing. Since a plurality of threaded holes 305 are provided on the top of the placing plate 301, the fixed position of the fixing plate 302 can be adjusted to fix automotive interior parts of different sizes, thereby improving the practicability. Since the fixed rod 24 drives the rectangular block 308 to move along with the connecting plate 207 through the driven plate 23, the blanking hole 309 is always located at the bottom of the punch 212, which has linkage and improves work efficiency. The positions of the punch 212 and the blanking hole 309 are opposite to each other to perform punching operations. Since the drive motor 202 is electrically connected to the telescopic rod 307 through the PLC controller 21, the two can be adjusted simultaneously for easy punching. When the punching position needs to be adjusted, when the rectangular block 308 is moving, the telescopic rod 307 can move along with the rectangular block. After starting the drive motor 202, rotate the threaded rod 205 to adjust the position of the hydraulic cylinder 210 through the moving block 206, thereby facilitating the adjustment of the position of the punch 212. Thus, punching can be performed on different positions of the automotive interior part without moving its position, which improves work efficiency. Since the collection box 16 abuts against the top of the bearing plate 7 and the collection box 16 is located at the bottom of the hole 310, the materials after punching can directly fall into the collection box 16 for easy collection. Since the clamping plate 209 and the connecting plate 207 are clamped through the connecting card slot 208, it is convenient to disassemble the punch 212 and the hydraulic cylinder 210 from the guide plate 201 for easy replacement of the punch 212. Start the dust suction pump 17 through the dust suction head 5 and the universal pipe 13 to suck the debris generated during punching into the dust collection box 14. It is also possible to adjust the universal pipe 13 to suck the dust on the outer surface of the automotive interior part into the dust collection box 14 through the dust suction head 5. This not only improves the processing quality but also protects the physical health of the staff and improves safety. The storage box 11 can store used or spare items, which is convenient for the staff to replace the used parts. An adsorption plate 19 is provided in the dust collection box 14 to adsorb the miscellaneous dust in the dust collection box 14 for easy cleaning. Since the collection box 16 abuts against the top of the bearing plate 7 and the collection box 16 abuts against the bearing plate 7, it is convenient for the staff to take out the collection box 16. Two storage boxes 11 are provided to improve the storage effect.An adsorption plate 19 is arranged in the dust collection box 14 to prevent the miscellaneous dust in the dust collection box 14 from flying around randomly.
