DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a stamping tool for an automobile cantilever, comprising a fixing plate 1, an upper pressing plate 10 and a lower pressing plate 16. The fixing plate 1 is used to fix the cantilever 2, and the cantilever 2 is arranged in a "C" shape. The cavity in the cantilever 2 gradually becomes larger from one end to the other end, and the end of the cantilever 2 to be stamped is the end with a smaller cavity. A mounting groove 3 for mounting the cantilever 2 is provided on the fixing plate 1. A stamping table 4 for fixing the end of the cantilever 2 to be stamped is fixed on the fixing plate 1 by screws, and the cantilever 2 covers the side of the stamping table 4 close to the cantilever 2. A fixing block 5 for fixing the other end of the cantilever 2 is fixed on the fixing plate 1 by screws, and the cantilever 2 covers the side of the fixing block 5 close to the cantilever 2. The upper pressing plate 10 and the lower pressing plate 16 press against the fixing plate 1, so that two symmetrical circular holes are punched out on both sides of the cantilever 2 on the stamping table 4. The lower pressing plate 16 has a mounting cavity 23 for mounting the fixing plate 1 on one side thereof, and the upper pressing plate 10 covers the lower pressing plate 16. When the upper pressing plate 10 and the lower pressing plate 16 are pressed against the fixing plate 1 at the same time, the upper pressing plate 10 and the lower pressing plate 16 are in contact with each other.

[0038] Reference Figure 1 and Figure 2 , a limiting column 18 is fixed by a screw on the side of the lower pressing plate 16 close to the upper pressing plate 10, and a limiting groove 19 is provided on the lower pressing plate 16 for the limiting column 18 to slide. When the upper pressing plate 10 and the lower pressing plate 16 are pressed against the fixed plate 1, the limiting column 18 slides in the limiting groove 19. The limiting column 18 presses against the upper pressing plate 10 in the limiting groove 19, thereby reducing the relative sliding of the upper pressing plate 10 and the lower pressing plate 16. In this embodiment, the limiting columns 18 are symmetrically arranged on both sides of the lower pressing plate 16. The upper pressing plate 10 and the lower pressing plate 16 are correspondingly provided with gaskets 15 in the direction of approaching each other to reduce the wear of the upper pressing plate 10 and the lower pressing plate 16 when they collide with each other.

[0039] Reference Figure 2 and Figure 3 , a movable block 6 for pressing the cantilever 2 to locate the position of the cantilever 2 to be punched is provided on the fixed plate 1, and an embedding groove 7 for the cantilever 2 to be embedded is provided on the movable block 6. The cantilever 2 is pressed against the movable block 6 in the embedding groove 7, thereby reducing the cantilever 2 from slipping on the movable block 6. A cylinder 8 for driving the movable block 6 to press against the cantilever 2 is fixed by screws on the side of the fixed plate 1 close to the movable block 6, and the movable block 6 is fixed on the piston column of the cylinder 8. The cylinder 8 drives the movable block 6 to press against the cantilever 2, thereby causing the cantilever 2 to slide to the side away from the movable block 6, and the cavity in the cantilever 2 for installing the fixed block 5 is reduced, thereby causing the cantilever 2 to press against the fixed block 5, thereby locating the punching position. A sliding groove 9 for the cantilever 2 to slide into the installation groove 3 is provided on the side of the fixed plate 1 close to the cantilever 2.

[0040] Reference Figure 2 and Figure 3 , combined with Figure 1 A first punching head 11 is provided on the side of the upper pressing plate 10 close to the fixed plate 1, a first punching groove 12 for the first punching head 11 to be pressed into is provided on the punching table 4, and a second punching groove 13 for the first punching head 11 to be pressed into is provided on the movable block 6, and the first punching groove 12 and the second punching groove 13 are combined to form a circular hole. When the upper pressing plate 10 presses against the fixed plate 1, the first punching head 11 punches the side of the cantilever 2 close to the upper pressing plate 10 on the punching table 4, so that the cantilever 2 is punched on the side of the cantilever 2 close to the upper pressing plate 10 on the punching table 4 to form a punching hole with a flange.

[0041] Reference Figure 2 and Figure 3 , combined with Figure 1 A pressing column 14 is fixed to the side of the upper pressing plate 10 close to the fixed plate 1 by screws, and a gasket 15 is provided on the fixed plate 1 for the pressing column 14 to press against. The pressing column 14 and the gasket 15 are pressed against each other, thereby reducing the wear of the upper pressing plate 10 and the fixed plate 1 when they are pressed against each other, and reducing the uneven force when the upper pressing plate 10 and the fixed plate 1 are pressed against each other. In this embodiment, the pressing columns 14 are evenly arranged at four.

[0042] Reference Figure 4 and Figure 5 , combined with Figure 1 A second punching head 17 is provided on the side of the lower pressing plate 16 close to the fixed plate 1, and the first punching groove 12 and the second punching groove 13 are used for the second punching head 17 to press in. When the lower pressing plate 16 presses against the fixed plate 1, the second punching head 17 punches the side of the cantilever 2 close to the lower pressing plate 16 on the punching platform 4, so that the cantilever 2 is punched on the side of the cantilever 2 close to the lower pressing plate 16 on the punching platform 4 to form a punching hole with a flange.

[0043] Reference Figure 4 and Figure 5, combined with Figure 1 A pressing block 22 is provided on the side of the fixed plate 1 close to the lower pressing plate 16. When the fixed plate 1 enters the installation cavity 23, the pressing block 22 presses against the lower pressing plate 16 in the installation cavity 23, thereby reducing the wear between the lower pressing plate 16 and the fixed plate 1. A limiting block 20 is provided on the side of the lower pressing plate 16 close to the fixed plate 1. A limiting cavity 21 is provided on the fixed plate 1 for the limiting block 20 to be inserted. The limiting block 20 presses against the fixed plate 1 in the limiting cavity 21, thereby reducing the slippage between the lower pressing plate 16 and the fixed plate 1.

[0044] Usage process:

[0045] 1. Insert the cantilever 2 into the sliding groove 9 and slide it into the installation groove 3 through the sliding groove 9. At this time, the punching table 4 and the fixing block 5 enter the cavity in the cantilever 2.

[0046] 2. The cylinder 8 drives the movable block 6 to press in the direction of the cantilever 2 until the movable block 6 contacts the punching table 4. At this time, the cantilever 2 enters the embedding groove 7, and the movable block 6 drives the cantilever 2 to slide until the cantilever 2 contacts the fixed block 5, thereby locating the position to be punched.

[0047] 3. The upper pressing plate 10 and the lower pressing plate 16 are pressed against the fixed plate 1 at the same time. At this time, the first punch head 11 punches the cantilever 2 on the punching table 4 on the side close to the upper pressing plate 10, and the second punch head 17 punches the cantilever 2 on the punching table 4 on the side close to the lower pressing plate 16, so that the cantilever 2 is punched on both sides of the punching table 4 to form symmetrical punching holes with flanges.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
