[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1, as Figures 1 to 3 As shown, this utility model is a waste edge cutting and unloading device, including a gantry frame 1. The gantry frame 1 is provided with an upper worktable 4 and a lower worktable 12 at the top and bottom respectively. The upper worktable 4 is connected to a hydraulic cylinder 2. A punching upper die 5 is installed on the upper worktable 4. A punching lower die 21 is provided on the lower worktable 12. A support block 11 is fixed at the bottom of the punching lower die 21. An arc-shaped support groove is provided at the top of the support block 11. An arc-shaped cleaning plate 14 is provided above the arc-shaped support groove. An avoidance opening for the punching lower die 21 is provided in the middle of the cleaning plate 14. Lifting cylinders 13 are fixed at both the front and rear ends of the cleaning plate 14. A pusher plate 19 is provided on one side of the cleaning plate 14. The bottom of the pusher plate 19 is arc-shaped. The pusher plate 19 is connected to a pusher cylinder 18. A waste edge receiving groove 7 is provided on the side opposite to the pusher plate 19 of the cleaning plate 14.

[0020] During operation, the workpiece is placed on the lower die 21, the device is activated, and the hydraulic cylinder 2 extends, causing the upper worktable 4 to descend. The upper die 5 descends with the upper worktable 4 and cooperates with the lower die 21 to trim the waste edges of the workpiece. The trimmed waste edges fall onto the cleaning tray 14, which is in a descending state and located in the arc-shaped support groove of the support block 11, without affecting the trimming operation. After trimming is completed and the workpiece is removed, the hydraulic cylinder 2 retracts, causing the upper worktable 4 to rise and reset. Then, the lifting cylinder 13 extends, causing the cleaning tray 14 to rise and lift the waste edges generated by trimming to the pushing height. The pushing cylinder 18 extends, causing the pushing plate 19 to move towards the waste edge, pushing the waste edges on the cleaning tray 14 into the waste edge receiving groove 7. After pushing is completed, the pushing cylinder 18 retracts, causing the pushing plate 19 to reset, and the lifting cylinder 13 retracts, causing the cleaning tray 14 to descend to the initial position.

[0021] In Example 2, based on Example 1, the inner end of the waste edge receiving groove 7 is located below the cleaning tray 14, and a receiving box 8 is provided below the outer end of the waste edge receiving groove 7. A scraper 9 is provided inside the waste edge receiving groove 7, and a linear slide rail 6 is provided on one side of the waste edge receiving groove 7. One end of the scraper 9 is fixed to the slider of the linear slide rail 6. After the pusher plate 19 pushes the waste edge, the slider of the linear slide rail 6 drives the scraper 9 to slide along the waste edge receiving groove 7, scraping the waste edge in the waste edge receiving groove 7 into the receiving box 8 for collection. After scraping is completed, the scraper 9 returns to its original position. The linear slide rail 6 can also be replaced with a magnetic couple type stainless steel rodless cylinder with sliding guide rail. The lower die 21 is arc-shaped, and a support groove is provided on the top surface of the lower die 21. A cutting blade is provided on the outside of the support groove. The bottom of the upper die 5 is arc-shaped and matches the support groove. A multi-degree-of-freedom robot arm for loading and unloading is provided on the front side of the lower worktable 12.

[0022] Below the pusher plate 19 is an arc-shaped waste receiving plate 22. A waste receiving cylinder 17 is fixedly connected to the bottom of the waste receiving plate 22. The waste receiving cylinder 17 is fixedly connected to a bracket, which is fixed on the lower worktable 12. The pusher cylinder 18 is fixedly installed on the bracket. When the lifting cylinder 13 extends and drives the cleaning tray 14 to rise, the waste receiving cylinder 17 extends, and the waste receiving plate 22 extends below the clearance opening on the cleaning tray 14 to catch the debris falling from the clearance opening.

[0023] The piston rod end of the pusher cylinder 18 is fixed with a support plate 23. The middle inner side of the support plate 23 is provided with an adjustment plate 24. The adjustment plate 24 is provided with a vertical strip-shaped adjustment hole. The strip-shaped adjustment hole is provided with a locking bolt for locking the adjustment plate 24.

[0024] The front and rear sides of the support plate 23 are fixed with guide rods symmetrical about the pusher cylinder 18. The guide rods are equipped with guide sleeves, which are fixed to the bracket.

[0025] Guide columns 20 and guide sleeves 16 that cooperate with each other are fixed on the lower worktable 12 and the upper worktable 4, respectively.

[0026] Below the receiving plate 22, there is a U-shaped chip collection groove 15 arranged in the front-to-back direction. A scraper plate 26 is provided in the chip collection groove 15, and a scraper cylinder 25 is fixed to the outer end of the scraper plate 26. The scraper cylinder 25 is fixed on the lower worktable 12. When the scraper cylinder 25 extends, it can drive the scraper plate 26 to move in the chip collection groove 15, scraping the chips in the chip collection groove 15 to the front end. A chip collection bucket can be placed at the lower front end of the chip collection groove 15. A chip pusher plate can be installed above the receiving plate 22. The chip pusher plate is fixed on the bracket. When the receiving cylinder 17 retracts, the chip pusher plate scrapes the chips on the receiving plate 22 into the chip collection groove 15.

[0027] The upper worktable 4 is provided with an upper mounting platform 3 fixed on the gantry frame 1 at its top. The upper worktable 4 can be detachably installed on the upper mounting platform 3. The upper mounting platform 3 is fixedly connected to the hydraulic cylinder 2. The lower worktable 12 is provided with a lower mounting platform 10 fixed on the gantry frame 1 at its bottom. The lower worktable 12 can be detachably installed on the lower mounting platform 10.
