Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a structure for simultaneous side punching of left and right parts. Background Technology

[0002] In the field of sheet metal processing, especially in the stamping manufacturing of automotive parts, appliance housings, and engineering structural components, side punching technology is widely used. Traditional punching methods are mostly single-piece, single-station processing, meaning that each punching operation only completes the punching operation in one direction or on one side of the workpiece. This method is inefficient, has a long processing cycle, and involves many processes and frequent mold changes, which can easily cause production delays. In addition, in the processing of symmetrical workpieces, existing technologies usually use two sets of independent molds to process the left and right parts respectively. This not only increases equipment investment and mold costs, but also leads to the accumulation of dimensional errors due to repeated mold setting and debugging, reducing product consistency and assembly accuracy. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a structure for simultaneous side punching of left and right parts. This solves the problem that current punching methods are mostly single-piece, single-station processing, meaning that each punching operation only completes the punching operation of one direction or one side of the workpiece. This method is inefficient, has a long processing cycle, and involves many processes and frequent mold changes, which can easily cause production delays. In addition, in the processing of symmetrical workpieces, existing technologies usually use two sets of independent molds to process the left and right parts separately. This not only increases equipment investment and mold costs, but also leads to the accumulation of dimensional errors due to repeated mold setting and debugging, reducing product consistency and assembly accuracy.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a side punching structure for both left and right parts, comprising an upper die base and a lower die base. An upper pad is fixedly connected to the lower surface of the upper die base, and a lower pad is fixedly connected to the upper surface of the lower die base. Contouring pads are fixedly connected to both sides of the upper surface of the lower pad, and contour positioning blocks are fixedly connected to the upper surfaces of the contour pads. Product 1 and Product 2 are respectively provided on the two contour positioning blocks. An upper clamping plate, a stop plate, and an upper stripping plate are sequentially installed on the lower surface of the upper pad. Inserting knives are fixedly connected to both sides of the upper pad, and a side punching assembly is provided in the middle of the upper surface of the lower pad.

[0005] The side punching assembly includes a push block, which is slidably connected to both sides of the middle of the lower pad. The lower part of the adjacent surfaces of the push block is fixedly connected to an inner guide post. The outer wall of the inner guide post is equipped with a stripper plate. On one side of the stripper plate, the middle of the adjacent surfaces of the push block is fixedly connected to a punch. The middle of the lower pad is provided with a cutting edge, and two punches are provided on both sides of the cutting edge.

[0006] As a preferred embodiment of this utility model, a lower template is fixedly connected to the upper surface of the lower pad.

[0007] As a preferred embodiment of this utility model, a pressure plate is fixedly connected to the middle of the lower surface of the stop plate.

[0008] As a preferred embodiment of this utility model, the stripper plate and the pusher block are connected by a first equal-height sleeve, and the upper mold base, upper pad, upper clamping plate and stop plate are connected by a second equal-height sleeve.

[0009] As a preferred technical solution of this utility model, a spring is fixedly connected to the opposite side of the push block, and a spring is fixedly connected to the lower surface of the upper mold base. The bottom end of the spring is fixedly connected to the upper surface of the upper clamping plate.

[0010] As a preferred technical solution of this utility model, an inner guide post 2 is fixedly connected to one side of the lower surface of the upper pad, and the upper clamping plate and the stop plate are installed on the inner guide post 2.

[0011] As a preferred embodiment of this utility model, the lower mold base has lower pads fixedly connected to the four corners of its lower surface, and the bottom of each lower pad is fixedly connected to a lower support plate.

[0012] Compared with the prior art, this utility model provides a structure for simultaneous side punching of left and right parts, which has the following beneficial effects:

[0013] This type of simultaneous side-punching structure for left and right parts involves placing the raw materials for the left and right parts to be punched in Product Area 1 and Product Area 2 on the lower die plate, respectively. The raw materials are precisely positioned by contour positioning blocks and contour pads to prevent displacement. The upper die plate moves downward under hydraulic or mechanical pressure, pushing the stripper plate and pusher block to move in the punching direction. This drives the punch to move horizontally inward from both sides of the die along the inner guide post, cooperating with the cutting edge to complete the synchronous side-punching operation of the left and right workpieces. This ensures that the left and right parts can be punched simultaneously in the same stroke, which not only improves efficiency but also guarantees the symmetry and consistency of the two products.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figure 1-2 In this embodiment: a side punching structure for left and right parts simultaneously includes an upper die base 1 and a lower die base 8. An upper pad 2 is fixedly connected to the lower surface of the upper die base 1, and a lower pad 7 is fixedly connected to the upper surface of the lower die base 8. Contouring pads 14 are fixedly connected to both sides of the upper surface of the lower pad 7, and contour positioning blocks 13 are fixedly connected to the upper surface of the contour positioning blocks 14. Product 11 and Product 2 12 are respectively provided on the two contour positioning blocks 13. An upper clamping plate 3, a stop plate 4 and an upper stripping plate 5 are installed sequentially on the lower surface of the upper pad 2. Inserting knives 18 are fixedly connected to both sides of the upper pad 2, and a side punching assembly is provided in the middle of the upper surface of the lower pad 7.

[0020] The side punching assembly includes a push block 19, which is slidably connected to both sides of the middle part of the lower pad 7. The lower part of the adjacent surfaces of the push block 19 is fixedly connected to the inner guide post 23. The outer wall of the inner guide post 23 is equipped with a stripper plate 16. On one side of the stripper plate 16, the middle part of the adjacent surfaces of the push block 19 is fixedly connected to a punch 21. The middle part of the lower pad 7 is provided with a cutting edge 22, and two punches 21 are provided on both sides of the cutting edge 22.

[0021] In this embodiment, with the mold open, the operator or automatic feeding device places the left and right raw materials to be stamped into the product 11 area and product 2 12 area on the lower template 6, respectively. The raw materials are precisely positioned by the contour positioning block 13 and the contour pad 14 to prevent displacement. The upper mold base 1 moves downward under hydraulic or mechanical pressure. The pressure plate 15 first contacts the raw material and fixes its position to prevent the material from moving or rebounding during the stamping process. As the upper mold base 1 continues to move downward, it pushes the stripper plate 16 and the pusher block 19 to move in the punching direction, driving the punch 21 to be guided along the inner guide post 23 and move horizontally inward from both sides of the mold. It cooperates with the cutting edge 22 to complete the synchronous side punching operation of the left and right workpieces.

[0022] Furthermore, a lower template 6 is fixedly connected to the upper surface of the lower pad 7; a pressure plate 15 is fixedly connected to the middle of the lower surface of the stop plate 4; the stripper plate 16 and the push block 19 are connected by an equal-height sleeve 17; the upper mold base 1, upper pad 2, upper clamping plate 3 and stop plate 4 are connected by an equal-height sleeve 24; springs 20 are fixedly connected to the far side of the push block 19; springs 25 are fixedly connected to one side of the lower surface of the upper mold base 1; the bottom end of springs 25 is fixedly connected to one side of the upper surface of the upper clamping plate 3; an inner guide post 26 is fixedly connected to one side of the lower surface of the upper pad 2; the upper clamping plate 3 and the stop plate 4 are mounted on the inner guide post 26; lower pads 9 are fixedly connected to the four corners of the lower surface of the lower mold base 8; and a lower support plate 10 is fixedly connected to the bottom end of the lower pads 9.

[0023] After the stamping is completed, the mold begins to move upward. The punch 21 automatically returns to its original position under the elastic force of the spring 20. The push block 19 and the stripper plate 16 also reset. The side punching mechanism completes one complete cycle. The upper stripper plate 005 assists in the stripping action under the guidance of the stop plate 004, making it easy for the stamped workpiece to separate from the mold.

[0024] The working principle and usage process of this utility model are as follows: With the mold open, the operator or automatic feeding device places the left and right raw materials to be stamped into the product 11 area and product 2 12 area on the lower mold plate 6, respectively. The raw materials are precisely positioned by the contour positioning block 13 and contour pad 14 to prevent displacement. The upper mold base 1 moves downward under hydraulic or mechanical pressure. The pressure plate 15 first contacts the raw material and fixes its position, preventing material movement or rebound during stamping. As the upper mold base 1 continues to descend, it pushes... The stripper plate 16 and the pusher block 19 move in the punching direction, driving the punch 21 to move horizontally inward from both sides of the mold along the inner guide post 23. It works with the cutting edge 22 to complete the synchronous side punching operation on the left and right workpieces. After the punching is completed, the mold begins to move upward. The punch 21 automatically returns to its original position under the elastic force of the spring 20. The pusher block 19 and the stripper plate 16 also reset. The side punching mechanism completes one complete cycle. The upper stripper plate 005 assists in the stripping action under the guidance of the stop plate 004, making it easy for the punched workpiece to separate from the mold.
