Description

Technical Field

[0001] The utility model relates to the technical field of gasket processing, in particular to a gasket punching device. Background Art

[0002] As we all know, gasket punching is a key technology that uses molds and punching equipment to quickly and accurately shape gasket materials. This technology uses punching molds to stamp gasket materials to achieve mass production and shape customization of gaskets.

[0003] In the prior art, when processing gaskets, the size of the blanking gap directly affects the dimensional accuracy of the gasket. If the gap is too small, the material elastically recovers and the size of the blank increases. If the gap is too large, the tensile force on the material increases. After the blanking is completed, the material elastically recovers and the blank size is smaller than the die size. Substandard blanking dimensions will not only reduce work efficiency, but also increase production costs. In order to solve the above problems, a gasket blanking device is needed.

[0055] The function of the top plate 1 is to install the electric push rod 2. The function of the side plate 3 is to provide lateral support and fixation. The bottom plate 4 is the bottom support structure of the entire gasket punching device, used to carry the stamping assembly and the moving assembly. The function of the housing 5 is to protect the internal mechanical structure, and at the same time provide protection functions such as dust prevention and splash prevention.

[0056] First, refer to Figure 1 , in this embodiment, the stamping assembly includes: a long plate 6, a large Z-shaped plate 7, hexagon bolts 8, and a small Z-shaped plate 9. The long plate 6 is fixedly connected to the lower surface of the electric push rod 2. Each large Z-shaped plate 7 is detachably connected to the long plate 6. The number of large Z-shaped plates 7 is two. Each hexagon bolt 8 is installed on the large Z-shaped plate 7. The number of hexagon bolts 8 is four. Each small Z-shaped plate 9 is in contact with the large Z-shaped plate 7. The number of small Z-shaped plates 9 is two.

[0057] The long plate 6 serves as the basic structure of the stamping assembly, fixedly connected to the lower surface of the electric push rod 2, used to support and install other components. The large Z-shaped plate 7 is used to install and support the hexagon bolts 8 and the small Z-shaped plate 9. The function of the hexagon bolts 8 is to fix the large Z-shaped plate 7 to ensure the stability of the structure.

[0059] The shear column 10 is used to guide the stamping action and punch the raw material. The combination of the large spring 11 and the retaining ring 12 provides a buffering and reset function to reduce the impact and vibration during punching.

[0060] Secondly, refer to Figure 1, in this embodiment, the stamping assembly further includes: a short column 13, a support seat 14, a support groove, a support column 15, a support spring 16, and a support plate 17.

The support spring 16 further provides buffering to reduce the impact force.

[0062] Again, refer to Figure 1 , in this embodiment, the stamping assembly further includes: a central support platform 18 and a large round hole. The central support platform 18 is fixedly connected to the upper surface of the bottom plate 4, and both sides of each support plate 17 are slidably connected to the central support platform 18. The large round hole is formed in the central support platform 18.

[0063] The central support platform 18 serves as the core support structure of the entire stamping assembly, and the large round hole is used for stamping operations and positioning of the raw material.

[0064] In addition, refer to Figure 3 , in this embodiment, the moving assembly includes: a moving bar 19, a moving chain 20, a long bar 21, a rotating long plate 22, a small spring 23, and a rotating cylinder 24. The moving bar 19 is fixedly connected to the bottom plate 4 and the support plate 17. The moving chain 20 is installed on the moving bar 19. The long bar 21 is fixedly connected to the large Z-shaped plate 7. The rotating long plate 22 is rotatably connected to the long bar 21. One end of the small spring 23 is installed on the long bar 21, and the other end of the small spring 23 is installed on the rotating long plate 22. The rotating cylinder 24 is rotatably connected to the rotating long plate 22.

[0065] The moving bar 19 serves as the rotation basis of the moving assembly. The moving chain 20 is installed on the moving bar 19 to achieve linear movement. The function of the long bar 21 is to facilitate the fixing of the rotating long plate 22 on the large Z-shaped plate 7. The small spring 23 provides buffering and reset during rotation. The rotating cylinder 24 is used to engage with the ratchet teeth 28 to drive the rotating disc 27 to rotate.

[0066] Finally, refer to Figure 4, in this embodiment, the moving component further includes: a rotating sprocket 25, a rotating drum 26, a rotating disc 27, and a ratchet 28. Each rotating sprocket 25 is installed on the moving chain 20. The number of rotating sprockets 25 is two. The rotating drum 26 is fixedly connected to the two rotating sprockets 25. The rotating disc 27 is fixedly connected to the rotating drum 26. The ratchet 28 is fixedly connected to the rotating disc 27.

[0067] Through the combination of the rotating sprocket 25 and the rotating drum 26, power transmission is achieved. The rotating disc 27 and the ratchet 28 are used to achieve one-way rotation and locking at a specific position.

[0068] Working principle:

[0069] For this gasket punching device, the operator first places the raw material on the moving component, starts the electric push rod 2. The up and down movement of the electric push rod 2 drives the up and down movement of the long plate 6. The up and down movement of the long plate 6 drives the up and down movement of the large Z-shaped plate 7. The up and down movement of the large Z-shaped plate 7 drives the up and down movement of the long strip 21. The rotating long plate 22 is always engaged with the ratchet 28 under the restriction of the small spring 23. The ratchet 28 will rotate under the drive of the rotating drum 26, thereby driving the rotation of the rotating disc 27. The rotation of the rotating disc 27 drives the rotation of the rotating drum 26. The rotation of the rotating drum 26 drives the rotation of the rotating sprocket 25. The rotating sprocket 25 drives the movement of the moving chain 20. The moving chain 20 drives the movement of the raw material. The intermittent movement of the raw material is realized through the up and down movement of the electric push rod 2.

[0070] When punching the raw material, the downward movement of the output end of the electric push rod 2 will move the long plate 6 downward. At the same time, the large Z-shaped plate 7 will move downward. The downward movement of the large Z-shaped plate 7 will drive the small Z-shaped plate 9 downward. At the same time, the shear column 10 moves downward. The short column 13 first cuts a hole in the raw material. When the bottom of the large Z-shaped plate 7 touches the support plate 17, the support plate 17 moves downward. The central support platform 18 is fixed. The small Z-shaped plate 9 moves upward under the restriction of the central support platform 18. The shear column 10 moves downward into the large round hole and punches the raw material into the shape of a gasket. At the same time, the gasket falls out through the large round hole. When the electric push rod 2 moves upward, the support spring 16 restores the support plate 17 to its original state under the action of elastic potential energy. At the same time, the large spring 11 also restores the small Z-shaped plate 9 to its original state, finally realizing the function of punching the raw material once.

[0071] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0072] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
