Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve cover stamping die technology, specifically a clamping device for valve cover stamping die. Background Technology
[0002] In the valve cover stamping production process, the clamping device is a key component to ensure the stamping accuracy of the blank, and its performance directly affects product quality and production efficiency. However, the clamping mechanism and support structure of traditional clamping devices are in fixed positions and can only be designed for round plate blanks of a single specification. When it is necessary to change the blank size to produce valve cover products with different diameters and thicknesses, corresponding special tooling must be customized, which increases the tooling manufacturing cost. This patent mainly addresses this issue. Therefore, we propose a clamping device for valve cover stamping dies. Utility Model Content
[0003] The purpose of this invention is to provide a clamping device for valve cover stamping dies.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for a valve cover stamping die, comprising a mounting plate installed on the stamping die, wherein the mounting plate has a circular groove, a through groove, and an air cavity; a storage groove is provided on the inner side of the mounting plate; a moving block is slidably disposed in the storage groove; a support block is connected to the side of the moving block; the storage groove communicates with the circular groove; a connecting column is slidably disposed in the circular groove; the connecting column is connected to the moving block; the circular groove communicates with the through groove; the through groove communicates with the air cavity; a connecting plate is slidably disposed in the air cavity; a connecting rod is connected to the upper surface of the connecting plate; the connecting rod is slidably connected to the mounting plate; the upper end of the connecting rod is fixedly connected to a connecting ring; an adjusting screw is threadedly connected to the side of the connecting ring; and the adjusting screw is rotatably connected to the mounting plate.
[0005] As a further embodiment of this utility model: a limiting groove is provided in the mounting plate, a limiting block is slidably arranged in the limiting groove, and the side of the limiting block is fixedly connected to the moving block.
[0006] As a further embodiment of this utility model: an elastic pad is fixedly connected to one side of the movable block that is connected to the support block.
[0007] As a further embodiment of this utility model: the outer side of the connecting rod is made of rubber material, and the inner side of the connecting rod is made of metal material.
[0008] As a further embodiment of this utility model: a rubber block is fixedly connected to the other end of the connecting column. The rubber block has a cylindrical structure and its diameter is equal to that of the circular groove.
[0009] As a further embodiment of this utility model: the bottom end of the through groove is flush with the bottom end of the air cavity.
[0010] As a further embodiment of this utility model: a sealing gasket is fixedly connected to the lower surface of the connecting plate, the diameter of the sealing gasket is equal to the diameter of the air cavity, and the sealing gasket is located above the through groove.
[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows: 1. This utility model involves overlapping a circular plate-shaped blank onto a support block. Rotating the adjusting screw causes it to rotate in conjunction with the mounting plate, which in turn moves the threaded connecting ring. The connecting ring drives the connecting rod to slide along the mounting plate, thereby pushing the connecting plate in the air chamber downward. The downward movement of the connecting plate compresses the gas in the air chamber. The sealing gasket ensures that the air chamber is sealed. The gas smoothly enters the circular groove through the through groove, pushing the connecting column with the rubber block to move towards the storage groove. The moving block flexibly contacts and presses the blank through the elastic pad. It is suitable for blanks of different sizes, eliminating the need to customize different tooling for blanks of different sizes, and has low operating costs. 2. This utility model uses an elastic pad to directly contact the round plate blank, which can buffer the clamping force and avoid rigid compression that causes indentations and edge deformation on the blank surface.
[0012] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0016] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] Please see the appendix Figure 1 -Appendix Figure 4 This utility model discloses a clamping device for a valve cover stamping die, comprising a mounting plate 1 installed on the stamping die. The mounting plate 1 has a circular groove 11, a through groove 12 and an air cavity 15. The inner side of the mounting plate 1 has a storage groove 5. A moving block 6 is slidably arranged in the storage groove 5. A support block 8 is connected to the side of the moving block 6. The storage groove 5 communicates with the circular groove 11. A connecting column 9 is slidably arranged in the circular groove 11. The connecting column 9 is connected to the moving block 6. The circular groove 11 communicates with the through groove 12. The through groove 12 communicates with the air cavity 15. A connecting plate 13 is slidably arranged in the air cavity 15. A connecting rod 4 is connected to the upper surface of the connecting plate 13. The connecting rod 4 is slidably connected to the mounting plate 1. The upper end of the connecting rod 4 is fixedly connected to the connecting ring 3. An adjusting screw 2 is threadedly connected to the side of the connecting ring 3. The adjusting screw 2 is rotatably connected to the mounting plate 1. In practical use, the circular plate-shaped blank is overlapped on the support block 8. The adjusting screw 2 is rotated, which rotates in conjunction with the mounting plate 1, causing the threaded connecting ring 3 to move. The connecting ring 3 drives the connecting rod 4 to slide along the mounting plate 1, thereby pushing the connecting plate 13 in the air chamber 15 to move down. The downward movement of the connecting plate 13 compresses the gas in the air chamber 15. The sealing gasket 14 ensures that the air chamber 15 is sealed. The gas smoothly enters the circular groove 11 through the through groove 12, pushing the connecting column 9 with the rubber block 10 to move towards the storage groove 5. The moving block 6 flexibly contacts and presses the blank through the elastic pad 7.
[0018] Furthermore, a limiting groove 16 is provided in the installation plate 1, and a limiting block 17 is slidably arranged in the limiting groove 16. The side of the limiting block 17 is fixedly connected to the moving block 6. Specifically, the limiting block 17 slides along the limiting groove 16, limiting the movement range of the moving block 6.
[0019] Furthermore, an elastic pad 7 is fixedly connected to one side of the movable block 6 that is connected to the support block 8; Specifically, the elastic pad 7 buffers the clamping force to prevent the round plate blank from being crushed or deformed, thus achieving flexible clamping.
[0020] Furthermore, the outer side of the connecting rod 4 is made of rubber, and the inner side of the connecting rod 4 is made of metal. Specifically, it can improve the sealing of the joints.
[0021] Furthermore, a rubber block 10 is fixedly connected to the other end of the connecting column 9. The rubber block 10 has a cylindrical structure and the diameter of the rubber block 10 is equal to that of the circular groove 11. Specifically, the diameter is the same as that of the circular groove 11 to achieve sealing of the circular groove 11, prevent gas leakage, and ensure sufficient driving force.
[0022] Furthermore, the bottom end of the through groove 12 is flush with the bottom end of the air chamber 15; Specifically, the connection is achieved through the through slot 12.
[0023] Furthermore, a sealing gasket 14 is fixedly connected to the lower surface of the connecting plate 13. The diameter of the sealing gasket 14 is equal to the diameter of the air chamber 15, and the sealing gasket 14 is located above the through groove 12. Specifically, the sealing gasket 14 can improve the sealing performance of the joint.
[0024] Working principle: First, the circular plate-shaped blank is placed on the support block 8. The adjusting screw 2 is rotated, which rotates in conjunction with the mounting plate 1, causing the threaded connecting ring 3 to move. The connecting ring 3 drives the connecting rod 4 to slide along the mounting plate 1, thereby pushing the connecting plate 13 in the air chamber 15 downward. The downward movement of the connecting plate 13 compresses the gas in the air chamber 15. The sealing gasket 14 ensures that the air chamber 15 is sealed. The gas smoothly enters the circular groove 11 through the through groove 12, pushing the connecting column 9 with the rubber block 10 to move towards the storage groove 5. The moving block 6 flexibly contacts and presses the blank through the elastic pad 7, adapting to blanks of different sizes. There is no need to customize different tooling for blanks of different sizes, resulting in low operating costs. At this point, the entire workflow is complete.
