Description

Technical Field

[0001] The present invention relates to the technical field of diaphragm springs, and particularly relates to a stamping die for diaphragm springs. Background Art

[0002] Currently, when processing diaphragm springs, a stamping die is usually used to stamp a sheet material into a diaphragm spring with a specific shape and size. During the process of stamping a diaphragm spring with the existing stamping die, only one diaphragm spring can be stamped at a time. After stamping is completed, during the process of picking and placing the diaphragm spring, the stamping mechanism cannot work, resulting in a certain gap between each stamping operation. For the processing of a batch of diaphragm springs, a large amount of time is wasted, it is difficult to achieve continuous stamping and forming of the diaphragm spring, which is not conducive to the efficient and stable production work of the diaphragm spring, and reduces the work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a stamping die for diaphragm springs to solve the above problems existing in the prior art.

[0004] The technical solution of the present invention for solving the above technical problems is as follows:

[0005] A stamping die for diaphragm springs includes a base. An adjusting mechanism is provided inside the base, a bracket is provided on the top of the base, and a stamping mechanism is provided on the bracket;

[0006] The adjusting mechanism includes a motor vertically downwardly arranged at the top of the inner cavity of the base. A first bevel gear is provided on the output shaft of the motor. It also includes vertical blocks vertically upwardly arranged at the left and right ends of the bottom of the inner cavity of the base and cross plates horizontally arranged at the left and right ends of the opposite sides of the inner cavity of the base. The top of the vertical block is fixedly connected to the bottom of the cross plate. A first rotating rod is rotatably connected to the inside of the vertical block through a bearing. A second bevel gear meshing with the first bevel gear is provided at the middle end of the first rotating rod. A third bevel gear is provided on the outside of the first rotating rod located in the vertical block. A second rotating rod is rotatably connected to the inside of the cross plate through a bearing. A first gear is sleeved on the upper end of the second rotating rod located above the cross plate. A fourth bevel gear meshing with the third bevel gear is sleeved on the lower end of the second rotating rod located below the cross plate. A third rotating rod is rotatably connected to the top of the cross plate through a bearing. A second gear meshing with the first gear is provided at one end of the third rotating rod. A tooth ring penetrating through a round hole at the top of the base is meshed with the outside of the second gear. A pressure plate is provided at the top of the tooth ring. A plurality of placement cavities are arranged in an array on the top of both pressure plates with the second rotating rod as the center.

[0007] The beneficial effects of the present invention are as follows: By starting the motor, the motor drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear and the first rotating rod to rotate together. The first rotating rod drives the third bevel gear to rotate. The two third bevel gears cause the two fourth bevel gears to rotate in opposite directions simultaneously. The fourth bevel gear drives the second rotating rod and the first gear to rotate together. The first gear drives the second gear and the third rotating rod to rotate. The second gear drives the toothed ring and the pressure plate to rotate together, adjusting the angle of the pressure plate so that the diaphragm spring in one of the placement cavities rotates under the stamping mechanism for stamping. After the stamping mechanism finishes stamping, the motor causes the pressure plate to continue rotating, making the stamped diaphragm spring rotate to a suitable angle for convenient removal, and at the same time stamping the diaphragm springs in other placement cavities; not only can two diaphragm springs be stamped simultaneously, but also while removing the stamped diaphragm spring, other diaphragm springs can be stamped, reducing the time of the stamping gap, realizing continuous stamping and forming operation of the diaphragm spring, facilitating the efficient and stable production work of the diaphragm spring, and improving work efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Further, pulleys are provided at the bottom of the pressure plate, and the pulleys are slidably arranged on the top of the base.

[0010] Further, the bracket includes a support rod and a top plate. The support rod is vertically arranged at the front and rear ends of the top of the base, and the top plate is horizontally arranged at the top of the support rod.

[0011] Further, the stamping mechanism includes a hydraulic cylinder, a moving plate, and a top die. The hydraulic cylinder is vertically downward arranged in the middle of the top plate. The output end of the hydraulic cylinder is horizontally provided with the moving plate, and the top die adapted to the placement cavity is provided at both the left and right ends of the bottom of the moving plate.

[0012] The beneficial effect of adopting the above further is: The hydraulic cylinder pushes the moving plate and the top die to move simultaneously, so that the top die stamps the diaphragm spring inside the placement cavity.

[0013] Further, sliding holes are opened at the front and rear ends of the top of the moving plate, and the moving plate is slidably sleeved on the support rod through the sliding holes.

[0014] Further, a pushing mechanism is further included. The pushing mechanism includes a cavity opened in the pressure plate and corresponding to the placement cavity. An expansion rod is vertically upward provided at the bottom of the cavity. A bottom plate is horizontally provided at the top of the expansion rod. A bottom die penetrating the round hole at the bottom of the placement cavity is provided at the top of the bottom plate. A return spring is sleeved outside the expansion rod, and both ends of the return spring are respectively abutted against the bottom of the cavity and the bottom of the bottom plate.

[0015] The further beneficial effects of adopting the above are as follows: By placing the diaphragm spring inside the placement cavity, the diaphragm spring is located on top of the bottom die to support the diaphragm spring. When the stamping mechanism stamps the diaphragm spring, the diaphragm spring will move downward under the action of the top die. The diaphragm spring pushes the bottom plate and the bottom die to move and compress the return spring. After stamping is completed, the top die moves away from the diaphragm spring, and the bottom plate and the bottom die are reset under the action of the return spring, pushing the diaphragm spring and the waste to move. When the placement cavity rotates away from below the stamping mechanism, the diaphragm spring and the waste can be taken out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0022] Embodiment 1

[0023] As Figure 1 and Figure 2 shown, a stamping die for a diaphragm spring includes a base 1. An adjusting mechanism 2 is provided inside the base 1, and a bracket is provided on top of the base 1. A stamping mechanism 6 is provided on the bracket.

[0024] The adjusting mechanism 2 includes a motor 21 vertically and downwardly arranged at the top of the inner cavity of the base 1. A first bevel gear 22 is provided on the output shaft of the motor 21. It also includes vertical blocks 23 vertically and upwardly arranged at the left and right ends of the bottom of the inner cavity of the base 1 and cross plates 29 horizontally arranged at the left and right ends of the opposite sides of the inner cavity of the base 1. The top of the vertical block 23 is fixedly connected to the bottom of the cross plate 29. A first rotating rod 24 is rotatably connected inside the vertical block 23 through a bearing. A second bevel gear 25 meshing with the first bevel gear 22 is provided at the middle end of the first rotating rod 24. A third bevel gear 26 is provided outside the vertical block 23 on the first rotating rod 24. A second rotating rod 28 is rotatably connected inside the cross plate 29 through a bearing. A first gear 210 is sleeved on one end of the second rotating rod 28 above the cross plate 29. A fourth bevel gear 27 meshing with the third bevel gear 26 is sleeved on one end of the second rotating rod 28 below the cross plate 29. A third rotating rod 211 is rotatably connected to the top of the cross plate 29 through a bearing. A second gear 212 meshing with the first gear 210 is provided at one end of the third rotating rod 211. A toothed ring 213 penetrating through the circular hole at the top of the base 1 is meshed outside the second gear 212. A pressing plate 214 is provided at the top of the toothed ring 213. A plurality of placement cavities 215 are arranged in an array on the top of the two pressing plates 214 with the second rotating rod 28 as the center.

[0025] By starting the motor 21, the motor 21 drives the first bevel gear 22 to rotate. The first bevel gear 22 drives the second bevel gear 25 and the first rotating rod 24 to rotate together. The first rotating rod 24 drives the third bevel gear 26 to rotate. The two third bevel gears 26 make the two fourth bevel gears 27 rotate in opposite directions simultaneously. The fourth bevel gear 27 drives the second rotating rod 28 and the first gear 210 to rotate together. The first gear 210 drives the second gear 212 and the third rotating rod 211 to rotate. The second gear 212 drives the toothed ring 213 and the pressing plate 214 to rotate together, adjusting the angle of the pressing plate 214 so that the diaphragm spring in one of the placement cavities 215 rotates to the lower part of the stamping mechanism 6 for stamping. After the stamping mechanism 6 finishes stamping, the pressing plate 214 continues to rotate through the motor 21, so that the stamped diaphragm spring rotates to a suitable angle for convenient taking out, and at the same time, the diaphragm springs in other placement cavities 215 are stamped; not only can two diaphragm springs be stamped simultaneously, but also while taking out the stamped diaphragm spring, other diaphragm springs can be stamped, reducing the time of the stamping gap, realizing the continuous stamping and forming operation of the diaphragm spring, being beneficial to the efficient and stable production work of the diaphragm spring, and improving the work efficiency.

[0026] In specific implementation, the first gear 210 drives the second gear 212 to rotate, and then the second gear 212 drives the toothed ring 213 to rotate, reducing the rotation speed of the toothed ring 213 and the pressing plate 214, ensuring the stability of the pressing plate 214 during rotation, and preventing the diaphragm spring from flying out of the placement cavity 215 during rotation.

[0027] Example 2

[0028] As Figure 2 shown, this embodiment is a further improvement based on Embodiment 1, specifically as follows:

[0029] A pulley 216 is provided at the bottom of the pressure plate 214. The pulley 216 is slidably arranged on the top of the base 1, which has a supporting effect on the pressure plate 214 and can assist the pressure plate 214 to rotate at the same time.

[0030] Example 3

[0031] As Figure 1 and Figure 2 shown, this embodiment is a further improvement based on Embodiment 1, specifically as follows:

[0032] The bracket includes a support rod 4 and a top plate 5. The support rod 4 is vertically arranged at the front and rear ends of the top of the base 1, and the top plate 5 is horizontally arranged at the top of the support rod 4. By arranging a stamping mechanism 6 on the top plate 5, the stamping mechanism 6 can stably stamp the diaphragm spring.

[0033] Example 4

[0034] As Figure 2 shown, this embodiment is a further improvement based on any one of Embodiments 1 to 3, specifically as follows:

[0035] The stamping mechanism 6 includes a hydraulic cylinder 61, a moving plate 62 and a top die 63. The hydraulic cylinder 61 is vertically arranged downward in the middle of the top plate 5. A moving plate 62 is horizontally arranged at the output end of the hydraulic cylinder 61. Top dies 63 adapted to the placement cavity 215 are arranged at both the left and right ends of the bottom of the moving plate 62. By pushing the moving plate 62 and the top dies 63 to move simultaneously through the hydraulic cylinder 61, the top dies 63 stamp the diaphragm spring inside the placement cavity 215.

[0036] Sliding holes are formed at both the front and rear ends of the top of the moving plate 62. The moving plate 62 is slidably sleeved on the support rod 4 through the sliding holes, so that the moving plate 62 makes a linear up and down movement along the support rod 4, increasing the stability of the moving plate 62 when it moves.

[0037] Example 5

[0038] As Figure 3 shown, this embodiment is a further improvement based on any one of Embodiments 1 to 4, specifically as follows:

[0039] It further includes a pushing mechanism 3. The pushing mechanism 3 includes a cavity 35 formed inside the pressure plate 214 and corresponding to the placement cavity 215. A telescopic rod 31 is vertically arranged upward at the bottom of the cavity 35. A bottom plate 33 is horizontally arranged at the top of the telescopic rod 31. A bottom mold 34 passing through the round hole at the bottom of the placement cavity 215 is arranged at the top of the bottom plate 33. A return spring 32 is sleeved outside the telescopic rod 31. The two ends of the return spring 32 are respectively abutted against the bottom of the cavity 35 and the bottom of the bottom plate 33.

[0040] By placing the diaphragm spring inside the placement cavity 215, the diaphragm spring is located on the top of the bottom mold 34 to support the diaphragm spring. When the stamping mechanism 6 stamps the diaphragm spring, the diaphragm spring will move downward under the action of the top mold 63. The diaphragm spring pushes the bottom plate 33 and the bottom mold 34 to move and compress the return spring 32. After stamping is completed, the top mold 63 moves away from the diaphragm spring. The bottom plate 33 and the bottom mold 34 reset under the action of the return spring 32 to push the diaphragm spring and the waste to move. When the placement cavity 215 rotates away from below the stamping mechanism 6, the diaphragm spring and the waste can be taken out.

[0041] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
