Description

Technical Field

[0001] This utility model relates to the field of sealing gasket preparation, specifically a device for cutting the flash of rubber products. Background Technology

[0002] Gaskets are sealing components used in machinery, equipment, pipelines—anywhere fluid is present—and are used both internally and externally to provide a seal.

[0003] In current technology, after the gasket is formed, burrs will be generated on the edge of the gasket. In subsequent processing, the workers need to remove the burrs and then carry out vulcanization treatment to improve the performance of the gasket.

[0004] However, during the process of removing burrs from the sealing gasket, the gasket lacks fixation, which leads to easy movement of the sealing gasket and poor cutting accuracy. Therefore, a burr punching device for rubber products is proposed to address the above problems. Utility Model Content

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-5 As shown, a rubber product flash cutting device includes a frame 11, a base 19 fixedly connected to the top of the frame 11; a bracket 12 fixedly connected to the top of the frame 11, a first electric cylinder 13 fixedly connected to the bracket 12, a horizontal plate 14 fixedly connected to the output end of the first electric cylinder 13, a second electric cylinder 15 fixedly connected to the horizontal plate 14, a fixed frame 16 fixedly connected to the output end of the second electric cylinder 15, a top seat 17 fixedly connected to the bottom of the horizontal plate 14, and a cutting blade 18 fixedly connected to the middle of the fixed frame 16, the cutting blade 18 being sleeved on the top seat 17 and slidably connected thereto;

[0025] In use, the operator places the sealing gasket on top of the base 19, then activates the first electric cylinder 13. The first electric cylinder 13 moves the horizontal plate 14 downward, and the top seat 17 below the horizontal plate 14 moves downward to cover the top of the base 19. The base 19 and the top seat 17 cooperate to fix the sealing gasket. Then, the second electric cylinder 15 moves the fixing frame 16 downward. The fixing frame 16 moves downward along the surface of the top seat 17 to cut off the burrs on the surface of the sealing gasket. The structure of the top seat 17 and the base 19 can fix the sealing gasket, thereby reducing the movement of the sealing gasket during cutting and improving the cutting accuracy.

[0026] Furthermore, such as Figure 1-5 As shown, a plurality of vertical cylinders 21 are fixedly connected to the frame 11. Vertical rods are slidably connected inside the vertical cylinders 21. A support plate 22 is fixedly connected to the top of the vertical rod. A through groove is opened in the middle of the support plate 22. The base 19 is located in the middle of the through groove. A rod body 3 is fixedly connected to the bottom of the fixed frame 16. A spring 23 is fixedly connected to the top of the frame 11. The top of the spring 23 is fixedly connected to the bottom side of the support plate 22. The spring 23 is sleeved on the surface of the vertical rod.

[0027] In use, multiple vertical cylinders 21 are fixedly connected to the frame 11. Vertical rods are slidably connected inside the vertical cylinders 21. A support plate 22 is installed at the top of the vertical rod. The support plate 22 is used to set a working platform above the workbench for easy use. During punching, the fixing frame 16 pushes the support plate 22 down, thereby moving the support plate 22 down. After that, the waste edge falls from the through groove. A rod 3 is fixedly connected to the bottom of the fixing frame 16. The bottom of the rod 3 is used to push the support plate 22 down. The spring 23 is used to facilitate the upward movement of the support plate 22.

[0028] Furthermore, such as Figure 1-5 As shown, a guide post 41 is fixedly connected to the bracket 12. A sliding sleeve 42 is fixedly connected to the horizontal plate 14 and the fixing frame 16 at the corresponding position of the guide post 41. The sliding sleeve 42 is sleeved on the guide post 41, and the guide post 41 and the sliding sleeve 42 are slidably engaged with it. A positioning block 51 is fixedly connected to the top of the base 19. The top of the positioning block 51 is provided with a guide slope 52. A groove is opened at the bottom of the base 19 at the corresponding position of the positioning block 51. A buffer block 6 is fixedly connected to the bottom of the rod 3. The buffer block 6 is made of rubber or silicone. There are two second electric cylinders 15. The two first electric cylinders 13 are respectively located at both ends of the fixing frame 16.

[0029] In use, multiple guide posts 41 are fixedly connected to the bracket 12. The guide posts 41 are connected to the fixed frame 16 through the sliding sleeve 42 and the horizontal plate 14. This can improve the stability of the vertical movement of the fixed frame 16 and the horizontal plate 14, and facilitate the improvement of the punching accuracy. The positioning block 51 is fixedly connected above the base 19. The positioning block 51 is used to position the sealing gasket. The guide slope 52 is used to facilitate the insertion and placement of the sealing gasket. The buffer block 6 is used to buffer.

[0030] Working principle: During use, the operator places the sealing gasket above the base 19, then activates the first electric cylinder 13. The first electric cylinder 13 moves the horizontal plate 14 downward, and the top seat 17 below the horizontal plate 14 moves downward to cover the base 19. The base 19 and the top seat 17 cooperate to fix the sealing gasket. Then, the second electric cylinder 15 moves the fixing frame 16 downward. The fixing frame 16 moves downward along the surface of the top seat 17 to cut off the burrs on the surface of the sealing gasket. The structure of the top seat 17 and the base 19 can fix the sealing gasket, thereby reducing the movement of the sealing gasket during cutting and improving cutting accuracy. During use, multiple vertical cylinders 21 are fixed to the frame 11. Vertical rods are slidably connected inside the vertical cylinders 21, and a support plate 22 is installed at the top of the vertical rod. The support plate 22 is used to set a working platform above the workbench for easy use. During punching, its fixing frame 16 pushes the support plate 22 down, thereby moving the support plate 22 down. Then the waste edge falls from the through groove. The bottom of the fixing frame 16 is fixedly connected to the rod 3. The bottom of the rod 3 is used to push the support plate 22 down. The spring 23 is used to facilitate the upward movement of the support plate 22. During use, multiple guide posts 41 are fixedly connected to the bracket 12. The guide posts 41 are connected to the fixing frame 16 through the sliding sleeve 42 and the horizontal plate 14. This can improve the stability of the vertical movement of the fixing frame 16 and the horizontal plate 14, and facilitate the improvement of punching accuracy. The positioning block 51 is fixedly connected above the base 19. The positioning block 51 is used to position the sealing gasket. The guide slope 52 is used to facilitate the insertion and placement of the sealing gasket.
