Detailed Implementation

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0027] See Figure 1-4 The illustrated metal punching device for automotive parts includes a worktable 1. Multiple trapezoidal support frames 6 are arranged along the length of the front side of the worktable 1. A punch 11 is provided on the top surface of each trapezoidal support frame 6. A clamp is provided at each end of the front side of the worktable 1. A rectangular hole is provided on the rear side of the worktable 1. A sliding table 16, capable of sliding along its length, is provided within the rectangular hole. A vertical frame 12 is fixedly connected to the sliding table 16. A forward-extending horizontal plate 14 is fixedly connected to the upper end of the vertical frame 12. A stamping cylinder 13 is mounted on the horizontal plate 14. A punch 15, which punches towards the punch 11, is mounted at the lower end of the stamping cylinder 13.

[0028] By implementing the above technical solution, in use, the automotive metal part requiring punching 11 is placed on the trapezoidal support frame 6. Multiple trapezoidal support frames 6 support the automotive metal part, with both ends clamped by jigs. Then, the sliding table 16 slides, moving the punch 15 to the corresponding punching hole 11 position. The stamping cylinder 13 is activated, driving the punch 15 downwards to punch the automotive metal part. The punching is then performed sequentially via the sliding table 16. This automotive metal part punching device can clamp both ends of automotive metal parts with linearly arranged holes and punch 11 one by one. Each punching hole 11 position has an independently supported trapezoidal support frame 6 structure, resulting in better stability of the punching 11.

[0029] In this embodiment, to further provide a clamping structure, the clamp includes an inverted L-shaped support plate 2. The lateral extension of the support plate 2 is provided with a shaft hole 24 and an elongated guide hole 23. The elongated guide hole 23 is located inside the shaft hole 24. A cylinder 5 is mounted on the bottom surface of the lateral extension. The cylinder shaft of the cylinder 5 extends upward through the shaft hole 24 and is fixedly connected to a pressure plate 3. A side baffle 4, which slides within the elongated guide hole 23, is fixedly connected to the bottom side of the pressure plate 3. In use, the side baffle 4 is used to align and limit the two ends of the automotive metal part. Then, the cylinder 5 drives the pressure plate 3 to move vertically and cooperate with the lateral extension of the support plate 2 to clamp and release the two ends of the automotive metal part.

[0030] In this embodiment, a rear baffle 10 is fixedly connected to the workbench 1 between the rectangular hole and the trapezoidal support frame 6. This arrangement provides a stop and limit on the rear side of the automotive metal part, and works in conjunction with the side baffles 4 on both sides to achieve three-sided limiting, thereby improving the accuracy of the punching 11.

[0031] In this embodiment, the sliding table 16 is provided with a through-hole, and a lead screw is screwed into the hole. One end of the lead screw is rotatably mounted on the worktable 1, and the other end is axially connected to a drive motor 21 mounted on one side of the worktable 1. The drive motor 21 rotates to drive the lead screw, and with the sliding engagement of the sliding table 16, the sliding table 16 is driven in the left and right directions.

[0032] In this embodiment, at least two linear guide rods 19 are provided inside the rectangular hole, which slides through the sliding table 16. Sliding grooves 18 are provided on both sides of the rectangular hole, and sliders 17 that slide in conjunction with the sliding grooves 18 are provided on both sides of the sliding table 16. This arrangement prevents the sliding table from deflecting, providing stable guidance for the sliding table 16, and also improves the support performance of the sliding table 16.

[0033] In this embodiment, a first guide ramp 8 is provided on the front side of the workbench 1 below each of the trapezoidal support frames 6. With this arrangement, the waste material that is impacted and falls can slide down along the first guide ramp 8 and be easily collected.

[0034] In this embodiment, a waste collection box 7 is provided on the front side of the workbench 1; a hook 26 is provided on the rear side of the waste collection box 7, and two slots 22 corresponding to the hooks 26 are provided on the front side of the workbench 1. This arrangement allows for the centralized collection of falling waste using the waste collection box 7, and the detachable connection between the waste collection box 7 and the workbench 1 can be achieved by inserting the hooks 26 at both ends into the corresponding slots 22.

[0035] In this embodiment, a guide plate 9 is provided on the upper rear edge of the waste collection box 7, which contacts the workbench 1. The guide plate 9 is provided with a second guide slope that aligns with the first guide slope 8. Since there is still a gap between the waste collection box 7 and the workbench 1 after installation, the guide plate 9 can close this gap to prevent waste from falling through it.

[0036] In this embodiment, a plurality of pads 25 are arranged at the bottom rear side of the waste collection box 7. This arrangement provides lateral support to the bottom of the waste collection box 7.

[0037] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0039] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
