Description

Technical Field

[0001] This utility model relates to the field of shock absorber bracket punching technology, specifically to a punching mold for automotive shock absorber brackets. Background Technology

[0002] Shock absorbers are an important component of a car's suspension. Their main function is to reduce vehicle vibration and make the car ride smoothly. During driving, the shock absorbers will continuously reciprocate to absorb the vibration of the car wheels, converting mechanical energy into heat energy, which is then dissipated by the air. The shock absorbers need to be connected to the car's suspension through brackets. The brackets are generally stamped parts, and holes need to be drilled in the brackets to connect them to the car body.

[0003] In traditional techniques, a bracket is placed below the punch, and then the hydraulic system is controlled to apply pressure to the punch head. After the punch head contacts the bracket, the punching is completed. However, when punching the bracket, holes need to be punched on both sides of the bracket simultaneously, which requires flanging during punching, greatly increasing the workload.

[0004] Therefore, it is particularly important to improve the existing punching dies for automotive shock absorber brackets, design a new type of punching die for automotive shock absorber brackets to solve the above-mentioned technical defects, and improve the overall practicality of the punching dies for automotive shock absorber brackets. Utility Model Content

[0005] The purpose of this utility model is to provide a punching die for an automotive shock absorber bracket. When punching holes in the automotive shock absorber bracket, the moving blocks are squeezed by the extrusion plate to bring the moving blocks closer to each other and complete the synchronous punching work on both sides, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A punching die for an automotive shock absorber bracket includes a worktable, a drive platform slidably connected to the top inner side of the worktable, a hydraulic rod inside the worktable with its output end fixedly connected to the drive platform, a first punch head fixedly connected to the middle of the bottom of the drive platform, an operating platform fixedly connected to the bottom of the worktable, and movable platforms symmetrically slidably connected to the top of the operating platform. A second punch head is fixedly connected to the adjacent ends of the two movable platforms, and inclined plates are fixedly connected to the distant ends of the movable platforms. A slot is provided inside the operating platform, and a placement groove is provided in the middle of the operating platform.

[0008] As a preferred embodiment of this utility model, baffles are fixedly connected to both ends of the top of the operating table, and a limit rod is slidably connected inside the baffle. The limit rod extends to one end of the moving table and is fixedly connected to the moving table. A buffer spring is sleeved on the side of the limit rod away from the baffle.

[0009] As a preferred embodiment of this utility model, the two ends of the bottom of the drive platform are symmetrically fixedly connected to the extrusion plates, the extrusion plates are designed with an inclined structure, the bottom of the extrusion plates are fixedly connected to the extension plates, and the extrusion plates extend into the interior of the slot.

[0010] As a preferred embodiment of this utility model, a pad is fixedly connected to one end of the top of the operating table, a mounting ear is fixedly connected to the top of the pad, and a driven rod is rotatably connected inside the mounting ear.

[0011] As a preferred embodiment of this utility model, a swing rod is rotatably connected to the bottom of the drive platform, the driven rod and the swing rod are designed in a cross structure, and the connection between the driven rod and the swing rod is a rotatable connection.

[0012] As a preferred embodiment of this utility model, the end of the driven rod away from the mounting ear is rotatably connected to a linkage rod, the end of the swing rod away from the drive platform is rotatably connected to a synchronizing rod, and a positioning pin is rotatably connected at the connection between the linkage rod and the synchronizing rod.

[0013] As a preferred embodiment of this utility model, a crossbar is fixedly connected to the outside of the positioning column, and a receiving hopper is fixedly connected to the outside of the crossbar. The inner side of the receiving hopper has an inclined structure design.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the drive table and the first punch head move downward and punch holes in the bracket. Then the extrusion plate contacts the inclined plate and the extrusion plate extends into the slot and applies a pushing force to the inclined plate, so that the moving table moves closer to each other on the top of the operating table. Then the second punch head moves closer to each other and completes the simultaneous punching of holes on both sides of the bracket.

[0016] 2. In this utility model, the drive table is lowered and pressure is applied to the swing rod to make the swing rod tilt. Then the driven rod and the swing rod approach each other and gradually tend to be parallel, so that the linkage rod and the synchronization rod approach each other, thereby extending the distance and making the receiving hopper extend outward to complete the discharge of the punching waste from the first punch head and the bracket.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-6 This utility model provides a technical solution:

[0026] A punching die for an automotive shock absorber bracket includes a worktable 1. A drive platform 2 is slidably connected to the top inner side of the worktable 1. A hydraulic rod is provided inside the worktable 1, and the output end of the hydraulic rod is fixedly connected to the drive platform 2. A first punching head 3 is fixedly connected to the middle of the bottom of the drive platform 2. An operating platform 4 is fixedly connected to the bottom of the worktable 1. Moving platforms 5 are symmetrically slidably connected to the top of the operating platform 4. A second punching head 6 is fixedly connected to the end of each of the two moving platforms 5 that are close to each other. An inclined plate 7 is fixedly connected to the moving platforms 5 that are far apart from each other. A slot is opened inside the operating platform 4, and a placement groove 8 is opened in the middle of the operating platform 4. By placing the bracket inside the placement groove 8, the hydraulic rod is then controlled to move, causing the drive platform 2 and the first punching head 3 to move down and punch the bracket. Then, the moving platforms 5 are brought closer together, which in turn causes the second punching heads 6 to move closer together, and then the bracket is punched on both sides.

[0027] Furthermore, in this embodiment, baffles 9 are fixedly connected to both ends of the top of the operating table 4. Limiting rods 10 are slidably connected inside the baffles 9. The limiting rods 10 extend to one end of the moving table 5 and are fixedly connected to the moving table 5. A buffer spring 11 is sleeved on the side of the limiting rods 10 that is away from the baffles 9. Extrusion plates 12 are symmetrically fixedly connected to both ends of the bottom of the drive table 2. The extrusion plates 12 have an inclined structure design. An extension plate 13 is fixedly connected to the bottom of the extrusion plates 12. The extrusion plates 12 extend into the interior of the slot. The drive table 2 presses them down, so that the first punch head 3 and the extrusion plates 12 descend synchronously. Then the extrusion plates 12 enter the interior of the slot. Then the extrusion plates 12 contact the inclined plate 7. As the extrusion plates 12 continue to extend into the interior of the slot and apply a pushing force to the inclined plate 7, the moving tables 5 move closer to each other on the top of the operating table 4. Then the second punch heads 6 move closer to each other, and the holes are punched synchronously on both sides of the bracket.

[0028] Furthermore, in this embodiment, a pad is fixedly connected to one end of the top of the operating table 4, and a mounting ear is fixedly connected to the top of the pad. A driven rod 14 is rotatably connected inside the mounting ear, and a swing rod 15 is rotatably connected to the bottom of the drive table 2. The driven rod 14 and the swing rod 15 are designed in a cross structure, and the connection between the driven rod 14 and the swing rod 15 is a rotatable connection. When the first stamping head 3 finishes its work, the drive table 2 descends and applies pressure to the swing rod 15 to tilt it. Subsequently, the driven rod 14 and the swing rod 15 approach each other and gradually become parallel.

[0029] Furthermore, in this embodiment, the driven rod 14 is rotatably connected to a linkage rod 16 at the end away from the mounting ear, and the swing rod 15 is rotatably connected to a synchronizing rod 17 at the end away from the drive platform 2. A positioning post is rotatably connected at the connection between the linkage rod 16 and the synchronizing rod 17. A crossbar 18 is fixedly connected to the outside of the positioning post, and a receiving hopper 19 is fixedly connected to the outside of the crossbar 18. The inner side of the receiving hopper 19 has an inclined structure design. When the driven rod 14 and the swing rod 15 approach each other and gradually tend to be parallel, the linkage rod 16 and the synchronizing rod 17 approach each other, thereby extending the distance and allowing the receiving hopper 19 to extend outward, thus completing the discharge of the punching waste from the first punch head 3 and the bracket.

[0030] In this embodiment, the specific implementation scenario is as follows: by placing the bracket inside the placement slot 8, and then controlling the hydraulic rod to move, the drive platform 2 and the first punch head 3 move downward and punch holes in the bracket. Then, the extrusion plate 12 enters the slot and contacts the inclined plate 7. As the extrusion plate 12 extends into the slot and applies a pushing force to the inclined plate 7, the moving platform 5 moves closer to each other at the top of the operating platform 4. Then, the second punch head 6 moves closer to each other, completing the synchronous punching of holes on both sides of the bracket. When the first punch head 3 finishes its work, the drive platform 2 descends and applies pressure to the swing rod 15 to tilt the swing rod 15. Then, the driven rod 14 moves closer to the swing rod 15 and gradually approaches a parallel state, so that the linkage rod 16 and the synchronization rod 17 move closer to each other, thereby extending the distance and allowing the receiving hopper 19 to extend outward, completing the discharge of the punched waste from the first punch head 3 and the bracket.
