The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0022] like Figs. 1 to 4 As shown, the present invention provides a cleaning device for stamping dies, comprising: a die body 1 and a cleaning mechanism 2 for cleaning the die; the die body 1 includes an upper die 12 and a lower die 11, and the upper die 12 is controlled to rise and fall by a hydraulic cylinder; an installation groove 13 is provided on the bottom of the inner wall of the die body 1, and the cleaning mechanism 2 is installed in the installation groove 13.
[0023] The cleaning mechanism 2 includes: a first support frame 22 and a second support frame 23. Both the first support frame 22 and the second support frame 23 are fixedly installed in the mounting groove 13, with the first support frame 22 positioned close to the lower mold 11. A rotating sleeve 27 is rotatably mounted on the first support frame 22 and the second support frame 23. A movable rod 28 is slidably mounted within the rotating sleeve 27. One end of the movable rod 28, near the lower mold 11, is fixedly connected to a cleaning brush 21. The cleaning brush 21 is aligned with the lower mold 11, and its shape is adapted to the mold, allowing it to remove waste materials from inside the mold as it passes through. The debris is removed; a limiting rod 24 is fixedly connected to the cleaning brush 21. The length of the limiting rod 24 is greater than the length of the lower mold 11 and less than the length of the moving rod 28. The limiting rod 24 is parallel to the moving rod 28. The limiting rod 24 prevents the cleaning brush 21 from shifting during movement, thus avoiding a decrease in cleaning effect. The limiting rod 24 slides and passes through the first support frame 22. A spring 25 is sleeved on the limiting rod 24. One end of the spring 25 is fixedly connected to the first support frame 22, and the other end of the spring 25 is fixedly connected to one end of the limiting rod 24.
[0024] By pushing the moving rod 28, the moving rod 28 pushes the cleaning brush 21 to clean the waste inside the mold. At the same time, the cleaning brush 21 drives the limiting rod 24 to move, and the limiting rod 24 compresses the spring 25. When the moving rod 28 loses its pushing force, the spring 25 pushes the limiting rod 24 to reset, the limiting rod 24 drives the cleaning brush 21 to reset, and the cleaning brush 21 drives the moving rod 28 to reset.
[0025] It should be noted that the tops of the cleaning brush 21, the first support frame 22, and the second support frame 23 are lower than the top of the lower die 11 to avoid the cleaning brush 21, the first support frame 22, and the second support frame 23 obstructing the feeding and positioning of the stamped parts.
[0026] Furthermore, chip removal grooves are provided at both ends of the lower mold 11. When the moving rod 28 pushes the cleaning brush 21 to move inside the mold, the cleaning brush 21 cleans out the waste chips inside the mold and pushes the waste chips into the chip removal groove at one end of the lower mold 11. During the process of the cleaning brush 21 resetting, it can clean the inside of the mold again, clean out the waste chips that were not cleaned and push them into the chip removal groove at the other end of the mold. Moreover, when the cleaning brush 21 is not working, it is located above the chip removal groove to prevent the waste chips attached to the cleaning brush 21 from falling into the mounting groove 13, which would make cleaning inconvenient.
[0027] A protrusion 29 is fixedly installed on the inner wall of the rotating sleeve 27, and a threaded groove 210 is provided on the moving rod 28. The protrusion 29 is slidably installed in the threaded groove 210. When the rotating sleeve 27 rotates forward, the protrusion 29 moves along the threaded groove 210 and pushes the moving rod 28 to move. The moving rod 28 drives the cleaning brush 21 to clean the waste inside the mold.
[0028] A take-up belt 26 is fixedly connected to the rotating sleeve 27. The take-up belt 26 is wound on the rotating sleeve 27 and fixedly connected to the upper mold 12 of the mold body 1. When the piston rod of the hydraulic cylinder pushes the upper mold 12 to complete the stamping, the take-up belt 26 is wound on the rotating sleeve 27. When the piston rod of the hydraulic cylinder drives the upper mold 12 to rise, the upper mold 12 pulls the take-up belt 26, causing the take-up belt 26 to stretch. The take-up belt 26 drives the rotating sleeve 27 to rotate. When the piston rod of the hydraulic cylinder descends and pushes the upper mold 12 to descend, the spring force of the spring 25 resets the moving rod 28. The threaded groove 210 on the moving rod 28 pushes the soil block to move along it, thereby causing the rotating sleeve 27 to reverse.
[0029] It should be noted that when the bottom of the upper mold 12 moves to the top of the lower mold 11, the cleaning brush 21 just comes into contact with the lower mold 11. This prevents the cleaning brush 21 from not leaving the inner wall of the mold when the upper mold 12 descends, which would affect the feeding of the part to be stamped. In addition, the length of the threaded groove 210 on the moving rod 28 enables the cleaning brush 21 to complete the cleaning of the inside of the mold.
[0030] Working principle:
[0031] When the stamping is completed, the piston rod of the hydraulic cylinder drives the upper die 12 to rise. The upper die 12 pulls the take-up belt 26, stretching it. The take-up belt 26 drives the rotating sleeve 27 to rotate clockwise. The rotating sleeve 27 drives the protrusion 29 to perform circumferential motion, and the protrusion 29 moves along the threaded groove 210, causing the protrusion 29 to push the moving rod 28 to move. The moving rod 28 pushes the cleaning brush 21 to move, cleaning the waste inside the die through the cleaning brush 21. At the same time, the cleaning brush 21 drives the limiting rod 24 to move. When the piston rod of the hydraulic cylinder pushes the lower mold 11 down, the spring 25 pushes the limit rod 24 to move in the opposite direction and reset. The limit rod 24 drives the cleaning brush 21 to reset, and the cleaning brush 21 drives the moving rod 28 to reset. The moving rod 28 pushes the protrusion 29 to make a reverse circumferential motion through the threaded groove 210, so that the rotating sleeve 27 reverses. The rotating sleeve 27 winds up the take-up belt 26, which can automatically clean the waste in the mold without manual operation, thus improving the practicality of the device.
