Description

Technical Field

[0001] This utility model relates to the field of vehicle shock absorber component manufacturing technology, specifically a mold for forming vehicle shock absorber structures. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving ride comfort. The connecting rod of the shock absorber is the part that connects the shock absorber piston to the base; it transmits force and absorbs shocks. The connecting rod is usually made of metal, possessing a certain strength and toughness. During the production of the inner tube of the connecting rod, one end needs to be stamped to form an inner folded limiting part to limit the positioning ring.

[0003] Chinese utility model patent application number 202420266777.1 provides a stamping die for shock absorber connecting rods. By setting a positioning mechanism, the positioning of the tube is more accurate during stamping. When the tube is inside the positioning cylinder, the bottom of the tube can be positioned. The combination of the support frame, connecting frame and positioning roller allows the positioning roller to position and support the middle position of the tube. The fixed positioning cylinder and support frame also avoid the upper side of the tube from shaking and shifting due to the movement of the tube.

[0004] However, during the use of the above equipment, it was found that shock absorbers for different car models need to be customized according to the vehicle structure, suspension system, performance requirements, etc., resulting in differences in the size, material and strength of the connecting rod. The positioning component in the equipment is limited to the production of a single car model. When producing different tubes, in order to fix tubes of different sizes, it is necessary to frequently change the mold, which increases costs. Changing the mold takes a lot of time and affects work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mold for forming vehicle shock absorption structures, which solves the problem mentioned in the background technology that when producing different pipe fittings, it is necessary to frequently change the mold to fix pipe fittings of different sizes, which increases costs and takes a lot of time, affecting work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold for forming a vehicle shock absorber structure, comprising a placement platform, a stamping assembly on the placement platform, a sliding groove in the middle annular array of the placement platform, a rotating cavity inside the placement platform, a worm gear rotatably mounted inside the rotating cavity, a vortex-shaped slide rail fixedly mounted on the worm gear, a sliding block slidably mounted on the vortex-shaped slide rail, a positioning component mounted on the sliding block, the positioning component including a positioning rod, the positioning rod being vertically mounted on the placement platform, a connecting block fixedly mounted at the bottom of the positioning rod, and the positioning rod being slidably mounted in the sliding groove through the connecting block.

[0007] Preferably, a worm is engaged on one side of the worm gear, the worm is mounted on a rotating shaft, the rotating shaft is rotatably mounted in a rotating cavity, and one end of the rotating shaft passes through a placement platform and is fixedly connected to a rotating handle.

[0008] Preferably, clamping components are provided at the top and bottom of one side of the positioning rod. The clamping components include clamping frames, which are bolted to the positioning rod. A clamping roller is rotatably mounted in the clamping frames.

[0009] Preferably, the stamping assembly includes a bracket, a mounting plate is mounted on the top of the bracket, an electric telescopic rod is mounted on the mounting plate, a movable plate is connected to the output end of the electric telescopic rod, a stamping cylinder is mounted on the movable plate, and a stamping head is provided on the output end of the stamping cylinder.

[0010] Preferably, the stamping head is detachably connected to the output end of the stamping cylinder, and the stamping head corresponds to the middle of the top of the placement platform.

[0011] Preferably, the mounting plate has a through groove in the middle, which corresponds to the stamping cylinder.

[0012] This utility model provides a mold for forming a vehicle shock absorber structure. It has the following beneficial effects:

[0013] (1) This utility model uses the rotation of the worm gear to make the sliding block move along the vortex slide, thereby driving the positioning rod to slide in the slide groove, realizing the quick positioning and fixing of pipes of different sizes. It does not require frequent mold changes to adapt to pipes of different sizes, which can improve work efficiency and reduce mold costs.

[0014] (2) This utility model drives the worm wheel to rotate through the worm gear. The worm gear transmission has a self-locking characteristic, which can ensure that the positioning rod maintains a stable position after the pipe is fixed and will not be displaced due to vibration or other external forces.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example 1:

[0024] Please see Figures 1-4 This utility model provides a mold for forming a vehicle shock absorption structure, including a placement platform 1, a stamping assembly 3 on the placement platform 1, a sliding groove 11 in the middle of the placement platform 1 in an annular array, a rotating cavity 12 inside the placement platform 1, a worm gear 121 rotatably installed inside the rotating cavity 12, a vortex slide 122 fixedly installed on the worm gear 121, a sliding block 123 slidably installed on the vortex slide 122, a positioning component 2 installed on the sliding block 123, the positioning component 2 including a positioning rod 21, the positioning rod 21 being vertically installed on the placement platform 1, a connecting block 22 being fixedly installed at the bottom of the positioning rod 21, and the positioning rod 21 being slidably installed in the sliding groove 11 through the connecting block 22;

[0025] A worm gear 124 is meshed on one side of the worm gear 121. The worm gear 124 is mounted on a rotating shaft 125. The rotating shaft 125 is rotatably installed in the rotating cavity 12. One end of the rotating shaft 125 passes through the placement platform 1 and is fixedly connected to the rotating handle 13.

[0026] Clamping components 23 are provided at the top and bottom of one side of the positioning rod 21. The clamping components 23 include clamping frames 231, which are bolted to the positioning rod 21. A clamping roller 232 is rotatably installed in the clamping frame 231.

[0027] Specifically, the pipe fitting is placed at the top center of the placement platform 1. Rotating the handle 13 causes the rotating shaft 125 to rotate, and the worm gear 124 on the shaft 125 rotates accordingly. Since the worm gear 124 meshes with the worm wheel 121, it drives the worm wheel 121 to rotate within the rotating cavity 12. When the worm wheel 121 rotates, the volute track 122 fixed on it also rotates. The sliding block 123 on the volute track 122 slides on the volute track 122 under the cooperation of the connecting block 22 and the slide groove 11. Simultaneously, the positioning rod 21 in the positioning component 2 installed on the sliding block 123 slides in the slide groove 11 through the connecting block 22, thereby adjusting the position of the positioning rod 21 on the placement platform 1 and moving it to a position suitable for the size of the pipe fitting to be processed.

[0028] When the positioning rod 21 is adjusted to the appropriate position, the clamping parts 23 set at the top and bottom of one side of the positioning rod 21 come into contact with and fit the pipe. The multiple positioning parts 2 can press the pipe from different directions to achieve stable fixation of the pipe.

[0029] By rotating the handle 13 to adjust the position of the positioning rod 21, the mold can adapt to pipes of different sizes, no longer limited to the production of a single vehicle model, thus improving the mold's versatility, reducing the need for frequent mold changes due to the production of different pipes, and lowering production costs.

[0030] The meshing transmission between the worm gear 124 and the worm wheel 121 has a precise transmission ratio, which can accurately control the rotation angle of the worm wheel 121, thereby precisely adjusting the position of the positioning rod 21 and achieving accurate positioning of the pipe fitting. This ensures the positional accuracy of the pipe fitting during the forming process. At the same time, the worm gear 121 and worm wheel 124 transmission has a self-locking characteristic, which can ensure that the positioning rod 21 maintains a stable position after the pipe fitting is fixed, and will not be displaced due to vibration or other external forces, which helps to improve product quality.

[0031] Furthermore, for details on stamping the fittings, please refer to [link / reference needed]. Figures 1-4The stamping assembly 3 includes a bracket 31, a mounting plate 32 is mounted on the top of the bracket 31, an electric telescopic rod 33 is mounted on the mounting plate 32, a movable plate 34 is connected to the output end of the electric telescopic rod 33, a stamping cylinder 35 is mounted on the movable plate 34, and a stamping head 36 is provided on the output end of the stamping cylinder 35.

[0032] The stamping head 36 is detachably connected to the output end of the stamping cylinder 35, and the stamping head 36 corresponds to the middle of the top of the placement table 1.

[0033] The mounting plate 32 has a through groove 321 in the middle, which corresponds to the stamping cylinder 35.

[0034] Specifically, the pipe fitting is stably fixed at the top center of the placement table 1 by the positioning member 2, which corresponds to the stamping head 36. The electric telescopic rod 33 installed on the mounting plate 32 is activated. The output end of the electric telescopic rod 33 extends and pushes the moving plate 34 connected to it to move downward. The stamping cylinder 35 descends with the moving plate 34 until it approaches the pipe fitting to be processed.

[0035] When the moving plate 34 descends to the appropriate position, the stamping cylinder 35 is activated. The output end of the stamping cylinder 35 extends, driving the stamping head 36 connected to its output end to apply pressure to the pipe in the middle of the top of the placement platform 1, performing a stamping operation on the pipe to complete the forming process of the pipe. After the stamping is completed, the output end of the stamping cylinder 35 retracts, driving the stamping head 36 away from the pipe. The slot 321 facilitates the movement of the stamping cylinder 35 and avoids the mounting plate 32 restricting or blocking the position of the stamping cylinder 35.

[0036] The stamping head 36 is detachably connected to the output end of the stamping cylinder 35, making it very convenient and quick to change stamping heads 36 of different types or sizes. When it is necessary to process pipe fittings of different shapes or specifications, only the corresponding stamping head 36 needs to be replaced, without the need for large-scale adjustment or replacement of the entire stamping assembly 3, which greatly improves the versatility and flexibility of the mold and reduces production preparation time and costs.

[0037] Working principle: The pipe to be processed is placed at the top center of the placement table 1. The handle 13 is rotated, which drives the rotating shaft 125 to rotate, thereby causing the worm gear 124 on the rotating shaft 125 to rotate. Since the worm gear 124 meshes with the worm wheel 121, the worm wheel 121 rotates in the rotating cavity 12. When the worm wheel 121 rotates, its fixed volute slide 122 also rotates. The sliding block 123 on the volute slide 122 slides on the volute slide 122 with the cooperation of the connecting block 22 and the slide groove 11. At the same time, the positioning rod 21 on the sliding block 123 slides in the slide groove 11 through the connecting block 22, moving the positioning rod 21 to a position suitable for the size of the pipe to be processed. When the positioning rod 21 is adjusted to the appropriate position, the clamping parts 23 on the top and bottom of one side of the positioning rod 21 come into contact with and fit the pipe. The multiple positioning parts 2 clamp the pipe from different directions, achieving stable fixation of the pipe and corresponding to the stamping head 36.

[0038] The electric telescopic rod 33 installed on the mounting plate 32 is activated. The output end of the electric telescopic rod 33 extends, pushing the moving plate 34 downward. The stamping cylinder 35 descends with the moving plate 34 until it approaches the pipe to be processed. When the moving plate 34 descends to the appropriate position, the stamping cylinder 35 is activated. The output end of the stamping cylinder 35 extends, driving the stamping head 36 to apply pressure to the pipe in the middle of the top of the placement platform 1, performing a stamping operation on the pipe to complete the forming process of the pipe.

[0039] After processing, the stamping cylinder 35 drives the stamping head 36 to return to its original position. The clamping roller 232 is set to facilitate the removal of the pipe from the positioning part 2, and at the same time facilitates the replacement of the pipe with the same size.
