DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6, the present utility model provides a technical solution: It includes a stamping table 1, on the surface of the stamping table 1, a baffle 8 is welded. The length of the baffle 8 is the same as the length of the longer side of the stamping table 1, and the baffle 8 is welded at the edge of the longer side of the stamping table 1. On the two shorter sides, collection covers 2 are fixed by bolts. The advantage of the two symmetrically arranged collection covers 2 is that they can collect the waste chips on the surface of the stamping table 1 more completely. At the bottom of the collection cover 2, an L-shaped collection pipe 3 is welded. One end of the collection pipe 3 far from the collection cover 2 is welded to an air suction pump 5. The two side collection pipes 3 are simultaneously welded to the air suction pump 5. The air suction pump 5 is fixed to the bottom of the stamping table 1 by bolts. At a position on the same horizontal plane as the air suction pump 5, there is a collection box 6. One end of the collection box 6 is welded to the air suction pump 5 through a pipeline. After starting the air suction pump 5, the waste chips generated on the surface of the stamping table 1 are collected through the collection cover 2, and then collected into the collection box 6 through the collection pipe 3. When the waste chips inside the collection box 6 are full, just open the box door of the collection box 6 to dispose of the waste chips. On the top of the stamping table 1, a cleaning assembly 7 is provided. The cleaning assembly 7 includes a driving box 701. The driving box 701 is fixed to the surface of the stamping table 1 by bolts and is arranged parallel to the baffle 8. Inside the driving box 701, there is a lead screw 702. Both ends of the lead screw 702 are fixed to the inner wall of the driving box 701 by bearings. One end of the lead screw 702 extends to the outside of the driving box 701 and is welded to the output end of the second driving motor 703. On the surface of the lead screw 702, a fixing block 704 is provided. The fixing block 704 slides left and right on the surface of the lead screw 702 through the internal thread structure. A rectangular slot is opened on the side of the driving box 701. On the side of the fixing block 704 close to the slot, a fixing shaft 705 is welded. One end of the fixing shaft 705 far from the fixing block 704 is welded with a slider 707. A chute 708 structure is opened on the side of the baffle 8. The slider 707 is arranged inside the chute 708. At the bottom end of the fixing shaft 705, a row of brushes 706 is adhered. The end of the brush 706 far from the fixing shaft 705 contacts the surface of the stamping table 1. When the second driving motor 703 drives the lead screw 702 to rotate, the fixing block 704 moves on the lead screw 702, driving the fixing shaft 705 to move. During the movement of the brush 706, the surface of the stamping table 1 is cleaned;

[0024] At the openings of the two collection hoods 2, a partition component 4 is provided. The partition component 4 includes a partition plate 405. A rotating shaft 401 is provided between the baffle 8 and the drive box 701. Both ends of the rotating shaft 401 are fixed to the side surface of the baffle 8 and the side surface of the drive box 701 through bearings respectively. The partition plate 405 is welded to the surface of the rotating shaft 401. A first drive motor 402 is fixed to the surface of the baffle 8 by bolts. A driving gear 403 is welded to the output end of the first drive motor 402. At a position on the same horizontal plane as the driving gear 403, a driven gear 404 is welded to the surface of the rotating shaft 401. The teeth of the driving gear 403 and the teeth of the driven gear 404 are meshed with each other. After the first drive motor 402 drives the driving gear 403 to rotate, the driving gear 403 drives the driven gear 404 to rotate, and then drives the partition plate 405 to perform a circular motion around the rotating shaft 401. The rotating shaft 401 is arranged beside the opening of the collection hood 2. When the partition plate 405 performs a rotational motion, the suction range of the collection hood 2 can be increased or decreased.

[0025] Working principle: During use, the utility model adjusts the opening size of the collection hood 2 by rotating the partition plate 405 to adapt to different forms of collecting waste chips. When the waste chips need to be cleaned after the punching table 1 is used, the first drive motor 402 is started. Driven by the first drive motor 402, the driving gear 403 drives the driven gear 404 to rotate, and then drives the rotating shaft 401 to rotate. The rotating shaft 401 rotates the partition plate 405 downward, making the opening of the collection hood 2 smaller, so that the suction force can be concentrated, and the waste chips can be collected more thoroughly. After collection, the waste chips are sucked into the collection box 6 through the collection pipe 3. When the waste chips need to be collected during the use of the punching table 1, the rotating shaft 401 is rotated to make the partition plate 405 rotate upward, making the opening of the collection hood 2 larger, so as to increase the range of collecting waste chips and avoid the waste chips floating in the air during the punching process; when there are waste chips attached to the surface of the punching table 1, the second drive motor 703 is started. Driven by the second drive motor 703, the lead screw 702 rotates, and then drives the fixed block 704 to move on the lead screw 702. The fixed block 704 drives the fixed shaft 705 to move left and right, so that the brush 706 at the bottom of the fixed shaft 705 cleans the waste chips on the surface of the punching table 1, and finally the waste chips are sucked by the suction pump 5.
