Description

[0002] Spiral elastic retaining rings are earless elastic retaining rings manufactured through a winding process. They are mainly used for axial positioning and fixing of mechanical parts and are widely used in aerospace, automotive, hydraulic systems and other fields.

[0003] Before use, the ends of the spiral elastic retaining ring need to be stamped to form the ring. However, during the stamping process, because the material of the spiral elastic retaining ring is thin and spiral-shaped, the excess material at the ends can easily be damaged by the stamping inertia after the stamping is cut off, resulting in cost loss. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping forming device for both ends of a spiral elastic retaining ring, so as to solve the problems mentioned in the background art.

[0006] Furthermore, the bottom of both the elevated platform and the workbench is fixedly connected to the surface of the base, and the end of the electric actuator passes through the top of the elevated platform and extends downwards.

[0007] Furthermore, the stamping mechanism includes a slide rod, a ring-shaped frame slidably connected to the surface of the slide rod, a lower pressure plate fixedly connected to the end of the ring-shaped frame away from the slide rod, a buffer elastic rod fixedly connected to the lower surface of the lower pressure plate, a stamping disc fixedly connected to the end of the buffer elastic rod away from the lower pressure plate, an upper cutting die fixedly connected to the lower surface of the lower pressure plate, a support plate fixedly connected to the end of the slide rod away from the ring-shaped frame, a placement disc fixedly connected to the end of the force-bearing elastic rod, a spiral elastic retaining ring provided on the surface of the placement disc, and extrusion plates fixedly connected to both ends of the lower pressure plate.

[0008] Furthermore, the output end of the electric actuator is fixedly connected to the upper surface of the lower pressure plate, the bottom of the spiral elastic retaining ring is in contact with the surface of the placement tray, the force-bearing elastic rod and the bottom of the lower cutting mold are both fixedly connected to the surface of the force-bearing plate, the end of the support plate away from the slide rod is fixedly connected to the bottom of the force-bearing plate, and the bottom of the slide rod is fixedly connected to the surface of the worktable.

[0009] Furthermore, the protective mechanism includes a sliding plate, the inner wall of which is slidably connected to a sliding plate, and the end of the telescopic right-angle plate away from the sliding plate is fixedly connected to an upper protective plate and a lower protective plate, and the surface of the telescopic right-angle plate is fixedly connected to a return spring.

[0010] Furthermore, the bottom of the elastic plate is fixedly connected to the surface of the workbench, the bottom of the telescopic right-angle plate is fixedly connected to the surface of the slide plate, the bottom of the slide plate is fixedly connected to the surface of the force plate, and there are two elastic plates, which are symmetrically arranged with the spiral elastic retaining ring as the center.

[0011] Furthermore, the limiting mechanism includes a telescopic sliding plate, a movable plate slidably connected to the surface of the telescopic sliding plate, a curved rod fixedly connected to the surface of the movable plate, and a limiting elastic rod fixedly connected to the bottom of the movable plate.

[0012] Furthermore, the end of the curved rod away from the moving plate is fixedly connected to the surface of the telescopic right-angle plate, both ends of the telescopic sliding plate are fixedly connected to the two sides of the force-bearing plate, and the end of the driven rod away from the push frame is rotatably connected to the surface of the moving plate.

[0013] The present invention has the following beneficial effects: This invention utilizes a stamping mechanism. First, a spiral elastic retaining ring is placed on the surface of a placement tray. Then, the two ends of the spiral elastic retaining ring are aligned with the upper and lower cutting dies. Next, an electric actuator is activated to push the lower pressure plate downwards. As the pressure plate moves, it causes the ring-shaped frame to slide downwards on the surface of the sliding rod. Simultaneously, it pushes the buffer elastic rod, the stamping tray, and the upper cutting die downwards, and also causes the extrusion plate to move downwards. During the downward movement of the stamping tray, it contacts the end of the spiral elastic retaining ring and pushes it to retract downwards. When the spiral elastic retaining ring retracts to its final position, it is stopped by the placement tray. When the spiral elastic retaining ring retracts to its final position, the stamping plate remains stationary. At this time, the electric push rod continues to push the lower pressure plate and the buffer elastic rod downwards, causing the buffer elastic rod to retract downwards. Meanwhile, the placement plate pushes the force-bearing elastic rod downwards. As the buffer elastic rod and the force-bearing elastic rod retract, the lower cutting die cuts the end of the spiral elastic retaining ring near the placement plate, while the upper cutting die cuts the upper end of the spiral elastic retaining ring. Effectively, by setting up the upper and lower cutting dies, both ends of the spiral elastic retaining ring can be cut simultaneously, thereby improving the efficiency of stamping.

[0014] This invention employs a protective mechanism. As the pressing plate moves downwards, it contacts the top of the elastic plate and compresses it. When the elastic plate is compressed, its middle section bends. This bending pushes a push plate closer to the other plate, which in turn pushes a telescopic right-angle plate closer to the other plate. As the telescopic right-angle plate moves, it causes a sliding plate to slide along the inner wall of the slide rail. Simultaneously, the movement of the telescopic right-angle plate pushes the upper protective plate towards the lower protective plate. Since there are two telescopic right-angle plates, the other one pushes the lower protective plate towards the upper protective plate. Because the spiral elastic retaining ring is spiral-shaped... As the upper protective plate moves, it moves to below the upper end of the spiral elastic retaining ring, while the lower protective plate moves to above the lower end of the spiral elastic retaining ring. When the stamping plate presses against the spiral elastic retaining ring and causes it to contract downwards, the upper and lower protective plates move downwards. The lower protective plate then causes the telescopic right-angle plate to contract downwards, pressing against the return spring. This effectively prevents damage to the spiral elastic retaining ring caused by the inertia generated during stamping, thus reducing costs, especially when the upper and lower cutting dies are cutting both ends of the spiral elastic retaining ring.

[0015] This invention employs a limiting mechanism. When the telescopic right-angle plate retracts downwards, it causes the bent rod and the moving plate to move downwards. As the moving plate moves, it causes the telescopic sliding plate, driven rod, push frame, and limiting ring to move downwards, bringing the limiting ring to the same horizontal level as the helical elastic retaining ring. Simultaneously, as the telescopic right-angle plates move towards each other, the bent rod moves towards the point of convergence. At this time, the bent rod pushes the moving plate to slide on the surface of the telescopic sliding plate towards convergence. As the moving plate slides, it pushes the driven rod towards convergence. The driven rod pushes the pusher and the limiting ring to move closer to each other, and the limiting ring contacts the outer wall of the spiral elastic retaining ring, thereby limiting the spiral elastic retaining ring. At the same time, as the moving plate moves, it squeezes the limiting elastic rod. When the limiting elastic rod is squeezed, it will contract in the direction of moving closer to each other. When the limiting elastic rod contracts to its full position, it will limit the two moving plates and prevent them from contacting each other. The limiting ring effectively limits the spiral elastic retaining ring and prevents displacement during the stamping process of the spiral elastic retaining ring.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 As shown, the present invention is a stamping forming device for both ends of a spiral elastic retaining ring, including a base 1, a high platform 2 fixedly connected to the surface of the base 1, an electric push rod 3 fixedly connected to the top of the high platform 2, a worktable 4 fixedly connected to the surface of the base 1, and also includes; The stamping mechanism 10 includes a force plate 18, on the surface of which a force-bearing elastic rod 19 is fixedly connected. The placement tray 20 pushes the force-bearing elastic rod 19 downward to retract. A lower cutting die 22 is fixedly connected to the surface of the force plate 18. When the two ends of the spiral elastic retaining ring 21 are aligned with the upper cutting die 16 and the lower cutting die 22, the lower cutting die 22 will cut the end of the spiral elastic retaining ring 21 near the placement tray 20 when the buffer elastic rod 14 and the force-bearing elastic rod 19 retract. The protective mechanism 30 includes a telescopic right-angle plate 33. At this time, the push plate 34 will push the telescopic right-angle plate 33 to move towards each other. The push plate 34 is fixedly connected to the surface of the telescopic right-angle plate 33. When the middle part of the elastic plate 35 bends, it will push the push plate 34 to move towards each other. The end of the push plate 34 away from the telescopic right-angle plate 33 is fixedly connected to the elastic plate 35. When the pressing plate 23 moves downward, it will contact the top of the elastic plate 35 and press the elastic plate 35. When the elastic plate 35 is pressed, the middle part will bend. The limiting mechanism 50 includes a driven rod 53. When the moving plate 52 slides, it pushes the driven rod 53 to move closer to each other. The end of the driven rod 53 is rotatably connected to a pusher 54. A limiting ring 55 is fixedly connected to the surface of the pusher 54. At this time, the driven rod 53 pushes the pusher 54 and the limiting ring 55 to move closer to each other, so that the limiting ring 55 moves to the same horizontal line as the spiral elastic retaining ring 21 and contacts the outer wall of the spiral elastic retaining ring 21, thereby limiting the spiral elastic retaining ring 21.

[0022] The bottom of both the elevated platform 2 and the workbench 4 are fixedly connected to the surface of the base 1, and the end of the electric push rod 3 passes through the top of the elevated platform 2 and extends downward.

[0023] The stamping mechanism 10 includes a slide rod 11, with a ring frame 12 slidably connected to the surface of the slide rod 11. When the lower pressure plate 13 moves, it drives the ring frame 12 to slide downward on the surface of the slide rod 11. The lower pressure plate 13 is fixedly connected to the end of the ring frame 12 away from the slide rod 11. A buffer elastic rod 14 is fixedly connected to the lower surface of the lower pressure plate 13. A stamping plate 15 is fixedly connected to the end of the buffer elastic rod 14 away from the lower pressure plate 13. At this time, the electric push rod 3 will continue to push the lower pressure plate 13 and the buffer elastic rod 14 downward, and at the same time, it will cause the buffer elastic rod 14 to retract downward. An upper cutting die 16 is fixedly connected to the lower surface of the lower pressure plate 13, and at the same time, it will push the buffer elastic rod 14, the stamping plate 15 and the upper cutting die 16 downward. The slide rod 11 moves away from the ring frame 11. One end of the plate 2 is fixedly connected to a support plate 17, and the end of the force-bearing elastic rod 19 is fixedly connected to a placement plate 20. The surface of the placement plate 20 is provided with a spiral elastic retaining ring 21. When the stamping plate 15 moves downward, it will contact the end of the spiral elastic retaining ring 21 and push the spiral elastic retaining ring 21 to contract downward. When the spiral elastic retaining ring 21 contracts to the end, it will be limited by the placement plate 20. When the spiral elastic retaining ring 21 contracts to the end, it will keep the stamping plate 15 stationary. The two ends of the lower pressure plate 13 are fixedly connected to the extrusion plate 23, which will also drive the extrusion plate 23 to move downward. The upper cutting die 16 and the lower cutting die 22 can effectively cut both ends of the spiral elastic retaining ring 21 at the same time, thereby improving the efficiency of stamping.

[0024] The output end of the electric actuator 3 is fixedly connected to the upper surface of the lower pressure plate 13. Then, the electric actuator 3 is activated to push the lower pressure plate 13 downward. The bottom of the spiral elastic retaining ring 21 contacts the surface of the placement tray 20. First, the spiral elastic retaining ring 21 is placed on the surface of the placement tray 20. The upper cutting mold 16 will cut the upper end of the spiral elastic retaining ring 21. The bottom of the force-bearing elastic rod 19 and the lower cutting mold 22 are both fixedly connected to the surface of the force-bearing plate 18. The end of the support plate 17 away from the slide rod 11 is fixedly connected to the bottom of the force-bearing plate 18. The bottom of the slide rod 11 is fixedly connected to the surface of the worktable 4.

[0025] The protective mechanism 30 includes a sliding plate 31, with a sliding plate 32 slidably connected to the inner wall of the sliding plate 31. When the telescopic right-angle plate 33 moves, it causes the sliding plate 32 to slide closer to each other on the inner wall of the sliding plate 31. Meanwhile, the lower protective plate 38 causes the telescopic right-angle plate 33 to retract downwards. The ends of the telescopic right-angle plate 33 furthest from the sliding plate 32 are fixedly connected to the upper protective plate 36 and the lower protective plate 38. When the stamping plate 15 presses the spiral elastic retaining ring 21 and causes it to retract downwards, the upper protective plate 36 and the lower protective plate 38 move downwards. As the telescopic right-angle plate 33 moves, it pushes the upper protective plate 36 towards the lower protective plate 38. Because the spiral elastic retaining ring 21 is spiral-shaped, the upper protective plate 36 will... When the spiral elastic retaining ring 21 is moved to the lower part of the upper end, since there are two telescopic right-angle plates 33, the other telescopic right-angle plate 33 will push the lower protective plate 38 to move towards the upper protective plate 36. The lower protective plate 38 will then move to the upper part of the lower end of the spiral elastic retaining ring 21. A return spring 37 is fixedly connected to the surface of the telescopic right-angle plate 33, and the return spring 37 is squeezed, thereby causing the return spring 37 to retract downward. This effectively prevents damage to the spiral elastic retaining ring 21 after cutting by the upper cutting mold 16 and the lower cutting mold 22, and reduces cost losses, by protecting it with the upper protective plate 36 and the lower protective plate 38.

[0026] The bottom of the elastic plate 35 is fixedly connected to the surface of the workbench 4, the bottom of the telescopic right-angle plate 33 is fixedly connected to the surface of the slide plate 32, the bottom of the slide plate 31 is fixedly connected to the surface of the force plate 18, and there are two elastic plates 35, which are symmetrically arranged with the spiral elastic retaining ring 21 as the center.

[0027] The limiting mechanism 50 includes a telescopic slide plate 51, a movable plate 52 slidably connected to the surface of the telescopic slide plate 51, and a curved rod 56 fixedly connected to the surface of the movable plate 52. When the telescopic right-angle plate 33 moves towards each other, it will drive the curved rod 56 to move towards the point of convergence. When the telescopic right-angle plate 33 retracts downward, it will drive the curved rod 56 and the movable plate 52 to move downward. A limiting elastic rod 57 is fixedly connected to the bottom of the movable plate 52. At the same time, the movable plate 52 will squeeze the limiting elastic rod 57 while moving. When the limiting elastic rod 57 is squeezed, it will retract towards each other. The setting of the limiting ring 55 can effectively limit the spiral elastic retaining ring 21 and prevent displacement during the stamping process of the spiral elastic retaining ring 21.

[0028] The end of the bent rod 56 away from the movable plate 52 is fixedly connected to the surface of the telescopic right-angle plate 33. When the limiting elastic rod 57 retracts to the end, it will limit the two movable plates 52 to prevent them from contacting each other. At this time, the bent rod 56 will push the movable plates 52 to slide towards each other on the surface of the telescopic slide plate 51. The two ends of the telescopic slide plate 51 are fixedly connected to the two sides of the force plate 18. The end of the driven rod 53 away from the push frame 54 is rotatably connected to the surface of the movable plate 52. When the movable plate 52 moves, it will drive the telescopic slide plate 51, the driven rod 53, the push frame 54 and the limiting ring 55 to move downward.

[0029] In use, first place the spiral elastic retaining ring 21 on the surface of the placement plate 20, align the two ends of the spiral elastic retaining ring 21 with the upper cutting mold 16 and the lower cutting mold 22, and then start the electric push rod 3 to push the lower pressure plate 13 downward. When the lower pressure plate 13 moves, it will drive the ring frame 12 to slide downward on the surface of the slide rod 11, and at the same time, it will push the buffer elastic rod 14, the stamping plate 15 and the upper cutting mold 16 downward, and also drive the extrusion plate 23 downward. When the stamping plate 15 moves downward, it will contact the end of the spiral elastic retaining ring 21 and push the spiral elastic retaining ring 21 downward to retract. When the spiral elastic retaining ring 21 retracts to the end, it will be limited by the placement plate 20. When the spiral elastic retaining ring 21 retracts to the end, it will keep the stamping plate 15 in place. Without moving, the electric actuator 3 continues to push the lower pressure plate 13 and the buffer elastic rod 14 downwards, causing the buffer elastic rod 14 to retract downwards. Meanwhile, the placement plate 20 pushes the force-bearing elastic rod 19 downwards. As the buffer elastic rod 14 and force-bearing elastic rod 19 retract, the lower cutting die 22 cuts the end of the spiral elastic retaining ring 21 near the placement plate 20, while the upper cutting die 16 cuts the upper end of the spiral elastic retaining ring 21. As the extrusion plate 23 moves downwards, it contacts the top of the elastic plate 35 and extrudes it. When the elastic plate 35 is extruded, its middle section bends. This bending pushes the push plate 34 towards each other. The telescopic right-angle plates 33 will be pushed to move closer to each other. When the telescopic right-angle plates 33 move, they will cause the slide plate 32 to slide closer to each other on the inner wall of the slide plate 31. When the telescopic right-angle plates 33 move, they will push the upper protective plate 36 to move towards the lower protective plate 38. Since there are two telescopic right-angle plates 33, the other telescopic right-angle plate 33 will push the lower protective plate 38 towards the upper protective plate 36. Since the spiral elastic retaining ring 21 is spiral, when the upper protective plate 36 moves, it will move to below the upper end of the spiral elastic retaining ring 21, while the lower protective plate 38 will move to above the lower end of the spiral elastic retaining ring 21. When the stamping plate 15 squeezes the spiral elastic retaining ring 21 and causes the spiral elastic retaining ring 21 to contract downwards... Simultaneously, the upper protective plate 36 and the lower protective plate 38 will move downwards. The lower protective plate 38 will cause the telescopic right-angle plate 33 to retract downwards, compressing the return spring 37, thus causing the return spring 37 to retract downwards. As the telescopic right-angle plate 33 retracts downwards, it will cause the bent rod 56 and the moving plate 52 to move downwards. When the moving plate 52 moves, it will cause the telescopic slide plate 51, the driven rod 53, the push frame 54, and the limiting ring 55 to move downwards, thus causing the limiting ring 55 to move to the same horizontal line as the spiral elastic retaining ring 21. As the telescopic right-angle plate 33 moves towards each other, it will cause the bent rod 56 to move towards the point of convergence. At this time, the bent rod 56 will push the moving plate 52 to slide towards each other on the surface of the telescopic slide plate 51.When the movable plate 52 slides, it pushes the driven rod 53 to move closer together. At this time, the driven rod 53 pushes the pusher 54 and the limiting ring 55 to move closer together, causing the limiting ring 55 to contact the outer wall of the spiral elastic retaining ring 21, thereby limiting the spiral elastic retaining ring 21. Simultaneously, as the movable plate 52 moves, it compresses the limiting elastic rod 57. When the limiting elastic rod 57 is compressed, it retracts towards the two moving plates. When the limiting elastic rod 57 retracts to its final position, it limits the movement of the two movable plates 52, preventing them from contacting each other.
