[0025] Embodiment three: Reference Figure 1-3 Compared with the first embodiment and the second embodiment, in this embodiment: the chip removal component 4 is used to blow air on the surface of the hardware after the punching to clean up the debris generated by the punching, and the chip removal component 4 includes a fixed rod 401, a fixed clamping ring 402, a folded corrugated cylinder 403, a bottom ring 404, a connecting rod 405, a connecting pipe 406, a fixed ring 407 and an air outlet 408. The top of one side of the vertical plate 301 is provided with a fixed rod 401, and the side of the fixed rod 401 away from the vertical plate 301 is provided with a fixed clamping ring 402, and the lifting plate 304 is close to A connecting rod 405 is provided on one side of the fixed clamp ring 402, and a bottom ring 404 is provided at the end of the connecting rod 405 away from the lifting plate 304, a folding bellows 403 is provided between the bottom ring 404 and the fixed clamp ring 402, and two connecting pipes 406 are provided at the bottom end of the folding bellows 403, and fixing rings 407 are provided on both sides of the top of the fixing plate 201, and the two connecting pipes 406 are connected to the two fixing rings 407 at one end away from the folding bellows 403, and an air outlet 408 is provided at one end of the fixing ring 407 away from the connecting pipe 406.

[0026] The two air outlets 408 are arranged in an inclined shape, and a filter screen 409 is provided at one end of the air outlet 408 away from the fixing ring 407, and the connecting rod 405 is arranged in an L shape.

[0027] In this embodiment, it should be noted that: the two inclined air outlets 408 are aligned with the punching position, and when the lifting plate 304 descends, the connecting rod 405 and the bottom ring 404 are driven to move downward, and the folding bellows 403 is pulled apart by folding. At this time, air is stored inside the folding bellows 403. When the punching is completed and the lifting plate 304 rises and resets, the bottom ring 404 rises and presses against the folding bellows 403, and the air inside the folding bellows 403 is squeezed out and discharged from the air outlet 408 through the connecting pipe 406, blowing away the debris formed on the top of the hardware due to the punching, so that it falls into the collection box 104 through the grid of the grid plate 102, and the debris is collected uniformly, and the staff regularly pulls out the collection box 104 to clean the debris inside it.

[0028] Embodiment 4: Reference Figure 1-2 as well as Figure 4-6Compared with the first, second and third embodiments, in the present embodiment: the conveying assembly 5 sequentially conveys the hardware that needs to be punched, and the conveying assembly 5 includes a connecting plate 501, a support rod 502, a docking rod 503, a rotating roller 504, a conveyor belt 505, a blocking rod 506, a rotating gear rod 507, a vertical rod 508, a rotating rod 509, a first bevel gear 510 and a second bevel gear 511. A connecting plate 501 is provided on one side of the workbench 1 close to the folding bellows 403, and support rods 502 are provided at both ends of the top end of the connecting plate 501 away from the workbench 1. The top end of the workbench 1 close to the connecting plate Docking rods 503 are provided at both ends of one side of 501, rotating rollers 504 are provided between the two support rods 502 and between the two docking rods 503, conveyor belts 505 are provided on the outside of the two rotating rollers 504, and multiple groups of blocking rods 506 are equidistantly provided on the outside of the conveyor belt 505, two rotating gear rods 507 are provided in the middle of the conveyor belt 505, and vertical rods 508 are provided at one end of the two rotating gear rods 507, and rotating rods 509 are provided at the ends of the two rotating gear rods 507 away from the vertical rods 508, and first bevel gears 510 and second bevel gears 511 are respectively provided at the ends of the two rotating rods 509 away from the rotating gear rods 507.

[0029] The transmission assembly 6 connects the conveyor belt 505 with the bidirectional screw rod 203, so that when the conveyor belt 505 rotates, the bidirectional screw rod 203 is driven to rotate forward and reversely, triggering the clamping assembly 2 to clamp the hardware. The transmission assembly 6 includes a connecting rod 601, a sleeve 602, a third bevel gear 603, a fourth bevel gear 604, an electrically controlled telescopic rod 605 and a connecting rod 606. A connecting rod 601 is provided at one end of the bidirectional screw rod 203 close to the connecting plate 501, and a sleeve 602 is provided at one end of the connecting rod 601 away from the bidirectional screw rod 203. The third bevel gear 603 and the fourth bevel gear 604 are provided on the sleeve 602. An electrically controlled telescopic rod 605 is provided at the bottom end of one side of the fixed plate 201 close to the sleeve 602, and the execution end of the electrically controlled telescopic rod 605 is connected to the connecting rod 606.

[0030] The bottom end of the vertical rod 508 is arranged at the top end of the connecting plate 501, the outer sides of the rotating roller 504 and the rotating gear rod 507 are meshed and connected with the inside of the conveyor belt 505, the connecting rod 606 is vertically connected with the execution end of the electric-controlled telescopic rod 605, the connecting rod 606 is rotatably connected with the sleeve 602 away from the execution end of the electric-controlled telescopic rod 605, the interior of the sleeve 602 is engaged and connected with the connecting clamping rod 601, and the third bevel gear 603 and the fourth bevel gear 604 are fixedly connected with the sleeve 602.

[0031] In this embodiment, it should be noted that: the baffles 506 at the top of the conveyor belt 505 are arranged at equal distances. When placing hardware, the hardware is placed between the two baffles 506 at intervals. When the rotating roller 504 rotates, it drives the conveyor belt 505 to rotate, and the hardware at the top is transported to the position of the placement frame 101, and falls into the placement frame 101 due to its own gravity.

[0032] When the transmission belt 505 rotates, it drives the two internally meshed rotating gear rods 507 to rotate, causing the two rotating rods 509 to rotate. At this time, the first bevel gear 510 and the second bevel gear 511 rotate, and the rotation direction of the first bevel gear 510 and the second bevel gear 511 is consistent with the rotation direction of the transmission belt 505.

[0033] The telescopic frequency of the electric telescopic rod 605 is set by a PLC controller with the model number "FX1N-24MR-D". When the electric telescopic rod 605 is extended, the connecting rod 606 and the sleeve 602 are extended. At this time, the inside of the sleeve 602 slides with the connecting rod 601, so that the fourth bevel gear 604 on the sleeve 602 approaches the second bevel gear 511 and meshes with it. At this time, the second bevel gear 511 drives the fourth bevel gear 604 and the sleeve 602, the connecting rod 601, and the bidirectional screw rod 203 to rotate forward, and the clamping plates 205 located on both sides of the bidirectional screw rod 203 approach each other to clamp and fix the hardware, and perform the punching operation.

[0034] When the drilling is completed, the electrically controlled telescopic rod 605 contracts, so that the third bevel gear 603 on the sleeve 602 is close to the first bevel gear 510. Since the third bevel gear 603 is connected to the back of the fourth bevel gear 604, the rotation of the first bevel gear 510 drives the third bevel gear 603 to rotate in the opposite direction, thereby realizing the reverse rotation of the bidirectional screw rod 203.

[0035] The conveyor belt 505 continues to rotate. At this time, the two baffle bars 506 located at the top of the transmission belt 505 where no hardware is placed rotate close to the placement frame 101, and cooperate with the two-way screw rod 203 to rotate in the opposite direction, so that the two clamping plates 205 move in opposite directions and remove the clamping of the hardware. At this time, the hardware that has been punched and chip removed can be manually taken out, and the above operation process is repeated as the conveyor belt 505 continues to rotate.
