Description
Technical Field
[0001] The utility model relates to an inclined wedge mechanism, in particular to a compact hook-punch inclined wedge mechanism. Background Art
[0002] In recent years, with the increasingly fierce competition in the automobile market, major automobile manufacturers have turned their attention to the automobile's own covering parts and related stamping parts (hereinafter collectively referred to as parts) in the direction of developing and researching new models, and have higher and higher requirements for them. Parts tend to be complex, high-strength, and various and complex, which makes it more difficult to manufacture molds, especially molds that require trimming and punching. For parts with trimming and punching at a certain angle, the existing technology uses conventional inclined wedge side punching molds, but this type of inclined wedge is only suitable for side trimming and punching on the outside of the part. For trimming and punching on the inside of the part, it will be greatly restricted in space and operation. In this case, the mold manufactured to achieve the function will greatly increase the various difficulties and costs. Utility Model Content
[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a compact hook-punch bevel wedge mechanism, which effectively solves the problem that the prior art adopts conventional bevel wedge side punching molds, but this type of bevel is only suitable for side trimming and punching on the outside of the workpiece. For trimming and punching on the inside of the workpiece, it will be greatly restricted in space and operation. In this case, the mold manufactured to achieve the function will greatly increase various difficulties and costs.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model includes a nitrogen spring top block, a nitrogen spring, a first guide slide cover plate, a guide plate, a buffer limit block, a second guide slide cover plate, a punching head, a workpiece, a die insert, a die insert mounting seat, a drive block base, a convex V guide plate and a slider, wherein the first guide slide cover plate, the guide plate and the second guide slide cover plate are mounted on the upper die seat by bolts, the slider is arranged between the first guide slide cover plate and the second guide slide cover plate, a nitrogen spring is embedded and installed inside the slider near the top, a nitrogen spring top block is installed at one end of the nitrogen spring, a buffer limit block is arranged at the top of one end of the slider, a punching head is installed at the bottom of one end of the slider, the die insert mounting seat and the drive block base are both mounted on the lower die seat by bolts, a die insert is installed on the die insert mounting seat, and a convex V guide plate is installed on one side of the top of the drive block base.
[0005] Preferably, the buffer limit block is mounted on the upper die base by bolts.
[0006] Preferably, the punching head is connected to the slider via bolts.
[0007] Preferably, the die insert is provided with a workpiece to be punched.
[0008] Preferably, the convex V-guide plate is connected to the driving block base by bolts.
[0009] Preferably, the top end of the nitrogen spring top block is mounted on the upper die base by bolts.
[0010] Beneficial effect: When the utility model is used, one action process includes two stages:
[0011] In the first stage, at the beginning, the upper die is at the top dead center of the machine tool, and the lower die is on the work surface of the punch press. The lower die is stationary during the entire working process. The slider is fully opened under the action of the nitrogen spring to reserve horizontal sliding space for the slider. When starting to work, the concave V inclined sliding surface at the rear end of the slider contacts the convex V guide plate, driving the slider to move to achieve the punching in the direction of the required punching angle. At the same time, the oblique driving stroke is converted into the horizontal movement stroke of the slider. Under the action of force, the nitrogen spring is compressed, and the slider and the buffer limit block open space to ensure space for the slider to retreat. When the upper die reaches the bottom dead center, the compression of the nitrogen spring reaches the maximum, and the punching head and the die insert complete the punching;
[0012] In the second stage, after the punching is completed, the upper die begins to open, and the concave V inclined sliding surface and the convex V guide plate gradually separate from the guide. At the same time, the compression of the nitrogen spring converted into horizontal movement begins to release, and the punching head is out of contact with the cutting edge of the lower die insert. The slider continues to slide until the compression of the nitrogen spring is completely released and is limited by the buffer limit block. At this time, the slider is completely released to reach the initial state, completing one action.
[0013] The utility model has a novel structure and an ingenious conception, and can trim and punch the inner side of a workpiece while being installed on the outer side, thereby greatly reducing the design difficulty of the mold structure to realize its function, reducing costs, increasing production stability, improving production efficiency, and ensuring the production quality of automobile parts.

The first guide slide cover plate 3, the guide plate 4 and the second guide slide cover plate 6 are mounted on the upper die seat by bolts, and the slider 13 is arranged on the first guide slide cover plate 3 and the first guide slide cover plate 6. Between the two guide slide cover plates 6, a nitrogen spring 2 is embedded and installed inside the slider 13 near the top, a nitrogen spring top block 1 is installed at one end of the nitrogen spring 2, a buffer limit block 5 is arranged on the top of one end of the slider 13, a punching head 7 is installed at the bottom of one end of the slider 13, a die insert mounting seat 10 and a driving block base 11 are both installed on the lower die seat by bolts, a die insert 9 is installed on the die insert mounting seat 10, and a convex V guide plate 12 is installed on one side of the top of the driving block base 11.
[0021] When used specifically: When the utility model is used, an action process includes two stages:
[0022] In the first stage, at the beginning, the upper die is at the upper dead center of the machine tool, and the lower die is on the working table of the punch press. The lower die is stationary during the entire working process. The slider 13 is fully opened under the action of the nitrogen spring 2, and horizontal sliding space is reserved for the slider 13. When starting to work, the concave V-shaped inclined sliding surface at the rear end of the slider 13 contacts the convex V-shaped guide plate 12, driving the slider 13 to move to achieve the punching in the direction of the required punching angle. At the same time, the oblique driving stroke is converted into the horizontal movement stroke of the slider 13. Under the action of force, the nitrogen spring 2 is compressed, and the slider 13 and the buffer limit block 5 are opened to ensure space for the slider 13 to retreat. When the upper die reaches the lower dead center, the compression of the nitrogen spring 2 reaches the maximum, and the punching head 7 and the die insert 9 complete the punching;
[0023] In the second stage, after the punching is completed, the upper die begins to open, and the concave V inclined sliding surface and the convex V guide plate 12 gradually disengage from the guide. At the same time, the compression of the nitrogen spring 2 converted into horizontal movement begins to release, and the punching head 7 is out of contact with the cutting edge of the lower die insert 9. The slider 13 continues to slide until the compression of the nitrogen spring 2 is completely released and is limited by the buffer limit block 5. At this time, the slider 13 is completely released to reach the initial state, completing one action.
[0024] Beneficial effects: The utility model has a novel structure and ingenious conception. It can trim and punch the inside of the workpiece while being installed on the outside, which greatly reduces the design difficulty of the mold structure to realize its function, reduces costs, increases production stability, improves production efficiency, and ensures the production quality of automotive parts.
