Description
Technical Field
[0001] This utility model relates to the field of automotive rubber parts processing technology, and in particular to an anti-deviation automotive rubber strip stamping and forming device. Background Technology
[0002] Automotive rubber strips are strip-shaped components made of rubber material. They achieve functions such as sealing, cushioning, and sound insulation through elastic deformation and are widely used in car doors, windows, windshields, engine hoods, trunk lids, sunroofs, and other parts.
[0003] Existing devices mostly rely on a single structure for fixation, and the fixation strength cannot adapt to the external impact during stamping. When the stamping die presses down on the rubber strip, the soft and smooth rubber strip is easily affected by the impact force, sliding laterally along the gap of the positioning structure or arching upwards, resulting in problems such as unclear texture pressing and misaligned cutting dimensions. Moreover, the positioning structure is mostly a static fixation design, which cannot adjust the fixation force according to the instantaneous force change during stamping. If the initial fixation is too loose, the risk of deviation during stamping increases significantly. If the initial fixation is too tight, although it can reduce some of the deviation probability, it will increase the difficulty of inserting the rubber strip and may cause the rubber strip to deform due to excessive clamping, which will affect the processing quality. This not only leads to a low rubber strip stamping pass rate and frequent rework, but also prolongs the processing cycle and increases labor and energy costs, making it difficult to meet the needs of large-scale and high-precision production of automotive parts. Utility Model Content
[0004] In view of the aforementioned problem of fixed offset, this utility model is proposed.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a stamping and forming device for anti-deviation automotive rubber strips, including a machine body, a top plate installed on the top of the machine body, a cylinder fixedly connected to the top of the top plate, a processing table fixedly connected to the top of the machine body, a processing groove opened on the top of the processing table, positioning plates for initial clamping of workpieces slidably connected to the left and right sides of the processing groove, multiple through holes opened at the end of the positioning plate near the workpiece, clamping blocks for secondary clamping slidably connected to the inner wall of the through holes, a moving plate for pushing the clamping blocks slidably connected to the inner wall of the positioning plate, a driving component for moving the clamping blocks installed on the inner wall of the moving plate, a stamping block for stamping fixedly connected to the output end of the cylinder, and a rod for moving the moving plate fixedly connected to the bottom end of the stamping block.
[0006] As a preferred embodiment of the anti-deviation automotive rubber strip stamping and forming device of this utility model, a drive motor is fixedly connected to either the left or right side of the machine body, and a bidirectional screw that is threadedly connected to the output end of the drive motor is fixedly connected to the positioning plate. An installation groove communicating with the left and right sides of the processing groove is opened on the inner wall of the machine body. Two through holes corresponding to the insertion rods are opened at the top of the processing table, and the top of the moving plate is slidably connected to the through holes.
[0007] As a preferred embodiment of the anti-deviation automotive rubber strip stamping forming device of this utility model, the drive assembly includes a ratchet rack, a clamping plate, a rotating gear, an elastic plate and a linear rack. A through hole extends through the moving plate, and a clamping plate is rotatably connected to the inner wall of the through hole near the moving plate. A torsion spring is installed inside the clamping plate. The clamping plate and the ratchet rack are engaged with each other, and the end of the ratchet rack near the workpiece is fixedly connected to the clamping block.
[0008] As a preferred embodiment of the anti-deviation automotive rubber strip stamping and forming device of this utility model, the front end of the clamping plate is rotatably connected to a rotating gear, the rotating gear meshes with a linear rack, and an elastic sheet for driving the clamping plate to disengage from the ratchet rack is fixedly installed on the side of the front end of the clamping plate near the ratchet rack. The elastic sheet is in contact with the rotating gear, and the end of the linear rack near the workpiece is fixedly connected to the inner wall of the positioning plate.
[0009] As a preferred embodiment of the anti-deviation automotive rubber strip stamping and forming device of this utility model, the outer wall of the rotating gear is provided with multiple notches for the elastic sheet to disengage from the rotating gear at a specific angle, and the lower end of the insert rod and the top end of the moving plate are both provided with mutually cooperating chamfers.
[0010] As a preferred embodiment of the anti-deviation automotive rubber strip stamping and forming device of this utility model, the inner wall of the mounting groove is fixedly connected with a plurality of guide rods penetrating the positioning plate, and a plurality of springs corresponding one-to-one with the moving plate are provided at the end of the mounting groove away from the positioning plate, one end of the spring is in contact with the mounting groove, and the other end of the spring is in contact with one end of the moving plate.
[0011] The beneficial effects of this utility model are: By using a bidirectional screw to move the positioning plates in opposite directions, the rubber strip can be initially clamped. This avoids stamping deviation caused by excessively loose initial fixation, while also preventing the rubber strip from becoming difficult to insert or deformed due to excessive tightness. During stamping, the cylinder drives the insert rod to push the moving plate, and the driving component extends the clamping block to achieve secondary fixation. This can adapt to the impact of external forces during stamping, preventing the rubber strip from sliding laterally or arching upwards, avoiding problems such as unclear texture pressing and cutting misalignment. Furthermore, during reset, the spring pushes the moving plate back to its original position, and the driving component releases the latch during the reset process of the positioning plate, causing the clamping block to reset synchronously. No additional operation or frequent adjustment of the fixing force is required, which improves the rubber strip stamping pass rate, reduces rework, shortens the processing cycle, reduces labor and energy costs, and meets the needs of large-scale, high-precision production.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1
[0022] Reference Figures 1-6 This is the first embodiment of the present invention, which provides an anti-deviation automotive rubber strip stamping and forming device, including a machine body 1, a top plate 2 installed on the top of the machine body 1, a cylinder 3 fixedly connected to the top of the top plate 2, a processing table 4 fixedly connected to the top of the machine body 1, a processing groove 5 opened at the top of the processing table 4, positioning plates 6 for initial clamping of workpieces slidably connected to the left and right sides of the processing groove 5, a plurality of through holes 10 opened at the end of the positioning plate 6 near the workpiece, a clamping block 11 for secondary clamping slidably connected to the inner wall of the through hole 10, a moving plate 9 for pushing the clamping block 11 slidably connected to the inner wall of the positioning plate 6, a driving component 12 for driving the clamping block 11 to move installed on the inner wall of the moving plate 9, a stamping block 19 for stamping fixedly connected to the output end of the cylinder 3, and an insert rod 20 for driving the moving plate 9 to move fixedly connected to the bottom end of the stamping block 19.
[0023] A drive motor is fixedly connected to either the left or right side of the machine body 1. The output end of the drive motor is fixedly connected to a bidirectional screw 8 that is threadedly connected to the positioning plate 6. The inner wall of the machine body 1 is provided with an installation groove 7 that communicates with the left and right sides of the processing groove 5. The top of the processing table 4 is provided with two through holes that correspond one-to-one with the insertion rod 20. The top of the moving plate 9 is slidably connected to the through holes.
[0024] The drive assembly 12 includes a ratchet rack 13, a clamping plate 14, a rotating gear 15, an elastic plate 16, and a linear rack 17. A through hole 10 extends through the moving plate 9. The clamping plate 14 is rotatably connected to the inner wall of the through hole 10 near the moving plate 9. A torsion spring is installed inside the clamping plate 14. The clamping plate 14 and the ratchet rack 13 are engaged with each other. The end of the ratchet rack 13 near the workpiece is fixedly connected to the clamping block 11.
[0025] During use, the automotive rubber strip to be processed is first placed in the processing groove 5 at the top of the processing table 4 to ensure that the processing part is centered. Then, the drive motor fixed on one side of the machine body 1 is started. The output end of the drive motor drives the bidirectional screw 8 to rotate. Since the bidirectional screw 8 is threadedly connected to the positioning plates 6 on the left and right sides, and the positioning plates 6 are slidably connected to both sides of the processing table 4 and have a guide rod 22 fixed through the inner wall of the mounting groove 7, the rotation of the bidirectional screw 8 will drive the two positioning plates 6 to move towards each other along the guide rod 22.
[0026] As the positioning plates 6 move towards each other, the side of the positioning plate 6 closest to the workpiece gradually adheres to the side wall of the workpiece until both positioning plates 6 clamp the workpiece together, completing the initial clamping and positioning. At the same time, the movement of the positioning plates 6 will cause the ratchet 13 and the linear rack 17 inside to move synchronously. The end of the ratchet 13 closest to the workpiece is fixedly connected to the clamping block 11, and the ratchet 13 and the clamping plate 14 rotatably connected to the inner wall of the through hole 10 are mutually engaged. The torsion spring inside the clamping plate 14 provides clamping force. Due to the cooperation characteristics of the ratchet 13 and the clamping plate 14, the ratchet 13 can only move in one direction and will not retract. The end of the linear rack 17 closest to the workpiece is fixed to the inner wall of the positioning plate 6. Its movement will cause the rotating gear 15 meshing with it to rotate clockwise. When the rotating gear 15 rotates, it squeezes the elastic piece 16 fixed at the front end of the clamping plate 14. After the elastic piece 16 is bent by the force, it does not affect the rotation of the rotating gear 15 to continue rotating until the initial clamping and positioning is completed, and then the drive motor is turned off. Example 2
[0027] Reference Figures 1-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a rotating gear 15 is rotatably connected to the front end of the clamping plate 14, the rotating gear 15 meshes with the linear rack 17, and an elastic piece 16 is fixedly installed on the front end of the clamping plate 14 near the ratchet 13 for driving the clamping plate 14 to disengage from the ratchet 13. The elastic piece 16 contacts the rotating gear 15, and the end of the linear rack 17 near the workpiece is fixedly connected to the inner wall of the positioning plate 6.
[0028] The outer wall of the rotating gear 15 has multiple notches 18 for disengaging the elastic plate 16 from the rotating gear 15 at a specific angle. The lower end of the insertion rod 20 and the top end of the moving plate 9 are both provided with chamfers that cooperate with each other.
[0029] Multiple guide rods 22 that penetrate the positioning plate 6 are fixedly connected to the inner wall of the mounting groove 7. Multiple springs 21 corresponding to the moving plate 9 are provided at the end of the mounting groove 7 away from the positioning plate 6. One end of the spring 21 contacts the mounting groove 7, and the other end of the spring 21 contacts one end of the moving plate 9.
[0030] During use, the cylinder 3 fixed at the top of the top plate 2 is activated. The output end of the cylinder 3 drives the stamping block 19 to move downward. The insertion rod 20 fixed at the bottom of the stamping block 19 moves downward synchronously. When the lower end of the insertion rod 20 contacts the top of the moving plate 9, since both have chamfers that cooperate with each other, the insertion rod 20 continues to move downward, which will push the moving plate 9 to move along the mounting groove 7 towards the workpiece. At the same time, it will squeeze the spring 21 corresponding to the moving plate 9 in the mounting groove 7.
[0031] When the moving plate 9 moves, the clamping plate 14 on the inner wall of its through hole 10 moves synchronously with the moving plate 9. The clamping relationship between the clamping plate 14 and the ratchet 13 drives the ratchet 13 to move towards the workpiece. The ratchet 13 then drives the clamping block 11 to slide along the inner wall of the through hole 10. Finally, the clamping block 11 extends out of the through hole 10 and presses tightly against the surface of the workpiece, completing the secondary clamping and fixing of the workpiece. During this process, the stamping block 19 continues to move down to stamp and form the workpiece after secondary fixing.
[0032] After stamping is completed, the control cylinder 3 drives the stamping block 19 to reset upwards. The insert rod 20 moves upwards synchronously with the stamping block 19 and disengages from the moving plate 9. At this time, the compressed spring 21 in the mounting groove 7 releases its elastic force and pushes the moving plate 9 to reset away from the workpiece.
[0033] Then, the drive motor is started, driving the bidirectional screw 8 to rotate in the opposite direction, causing the positioning plates 6 on both sides to reset along the guide rod 22 away from the workpiece. When the positioning plates 6 reset, they cause the linear rack 17 to move in the opposite direction. The linear rack 17 causes the rotating gear 15 to rotate counterclockwise. The rotating gear 15 pushes the elastic plate 16 in the opposite direction. After the elastic plate 16 is subjected to force, its bottom end causes the clamping plate 14 to rotate around the rotation point, so that the clamping plate 14 is disengaged from the ratchet 13. When the rotating gear 15 rotates to the position where its outer wall notch 18 corresponds to the elastic plate 16, the elastic plate 16 disengages from the rotating gear 15. The clamping plate 14 resets under the action of the internal torsion spring, but is caught by the tip of the next rotating gear 15, preventing the clamping plate 14 from jamming with the ratchet 13. At the same time, the resetting of the positioning plate 6 causes the clamping block 11 and the ratchet 13 to move away from the workpiece synchronously until the positioning plate 6 returns to the initial position. Then, the drive motor is turned off, the formed workpiece is removed, and it is ready for the next use.
[0034] The remaining structure is the same as that in Example 1.
[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
