Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for a steel plate spring clamp. Background Technique

[0002] A steel plate spring clamp is a metal fixture or fastener used to fix or connect steel plate springs. It is usually made of high-strength steel plates through processes such as stamping and bending, and has the characteristics of being firm, durable and easy to install. In the processing of steel plate spring clamps, stamping die forming is a crucial link. First, the steel plate materials are precisely cut and pre-treated to reach the dimensions and surface states suitable for stamping. Then, these steel plates are fed into a stamping machine and formed through a precisely designed stamping die.

[0003] For existing stamping dies, operators often need to manually adjust or rely on experience to ensure the accurate position of the plates, which not only reduces production efficiency but also increases the risk of errors. The inconvenience of positioning the plate length directly leads to an increase in production costs and instability of product quality. Secondly, after stamping, the adhesion and friction between the clamp and the die make it difficult to strip the material, which not only increases the labor intensity of the operator but also affects the overall operation efficiency of the production line, exacerbating the increase in production costs and instability of product quality. Therefore, we propose a stamping die for a steel plate spring clamp. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stamping die for a steel plate spring clamp to solve the problems in the above-mentioned background technique that for existing stamping dies, operators often need to manually adjust or rely on experience to ensure the accurate position of the plates, which not only reduces production efficiency but also increases the risk of errors. The inconvenience of positioning the plate length directly leads to an increase in production costs and instability of product quality. Secondly, after stamping, the adhesion and friction between the clamp and the die make it difficult to strip the material, which not only increases the labor intensity of the operator but also affects the overall operation efficiency of the production line, exacerbating the increase in production costs and instability of product quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel leaf spring clamp stamping die, comprising a base, positioning plates are provided on both sides of the top of the base, a groove is provided on one side of the positioning plate near the center, a lower die is fixedly installed at the center of the top of the base, a stamping groove is provided at the center of the top of the lower die, threaded grooves are provided on the bottom of two positioning plates, a bidirectional stud is provided at the bottom of the lower die, a motor is fixedly installed at the center of the top of the base, a push plate is provided at the top of the stamping groove, mounting grooves are provided at the four corners of the bottom of the stamping groove, push springs are fixedly connected to the inner bottoms of the four mounting grooves, a sliding plate is fixedly connected to the top of the push spring, and connecting rods are fixedly connected to the four corners of the bottom of the push plate.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The steel plate spring clamp stamping die is designed with a positioning plate, a thread groove, a groove, a bidirectional stud and a motor. When the control motor is running, it will drive the gear connected to it to rotate, and then engage another gear to drive the bidirectional stud to rotate. Since the thread grooves on the two positioning plates match the threads on both sides of the surface of the bidirectional stud, the two positioning plates will move horizontally relative to or away from each other on the lower die at the same time according to the rotation direction of the bidirectional stud. This design enables the steel plate to be positioned during stamping, and accurately positions steel plates of different lengths, effectively avoiding the problems of stamping deviation and increased scrap rate caused by inaccurate positioning. The design of the push spring plate, push spring, sliding plate and connecting rod makes it possible for the steel plate to be positioned during stamping. When the plate is deformed by force, pressure will be applied to the push spring plate inside the stamping groove, causing the push spring plate to move downward. During this movement, the connecting rod at the bottom of the push spring plate will shrink into the mounting groove, driving the sliding plate to move together, thereby compressing the push spring in the mounting groove. When the stamping is completed, the stamping force of the plate disappears. At this time, the push spring begins to play its reset role. Due to the elastic potential energy of the push spring, it will quickly push the sliding plate upward, and then drive the push spring plate to rise together through the connecting rod. During this rising process, the push spring plate will contact and push the formed steel plate spring clamp, allowing it to smoothly escape from the stamping groove, thereby realizing the function of rapid material removal and improving processing efficiency.

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0014] Please refer to Figures 1-4 , the present utility model provides a technical solution: a steel plate spring clamp stamping die, including a base 1. Positioning plates 4 are arranged on both sides of the top of the base 1. A groove 5 is opened at the center of one side of the positioning plate 4. The lower die 2 is fixedly installed at the center of the top of the base 1. A stamping groove 3 is opened at the center of the top of the lower die 2. Threaded grooves 6 are opened at the bottom of one side of the two positioning plates 4. A bidirectional stud 7 is arranged at the bottom of the lower die 2. A motor 8 is fixedly installed at the center of the top of the base 1. A material pushing elastic plate 10 is arranged at the top of the stamping groove 3. Installation grooves are opened at the four corners of the bottom of the stamping groove 3. The inner bottoms of the four installation grooves are fixedly connected with material pushing springs 11. The top of the material pushing spring 11 is fixedly connected with a sliding plate 12. Connecting rods 13 are fixedly connected to the four corners of the bottom of the material pushing elastic plate 10.

[0015] The inner diameter of the groove 5 is larger than the outer diameter of the lower die 2. The two ends of the lower die 2 respectively penetrate to the outside of the two grooves 5, so that the two positioning plates 4 can horizontally move on the surface of the lower die 2.

[0016] Support plates are fixedly installed on both sides of the lower die 2. The lower ends of the two support plates are fixedly connected to the top of the base 1. The two ends of the bidirectional stud 7 respectively penetrate to the outside of the two threaded grooves 6 and are respectively movably connected to the bearings fixedly installed at the bottom of the opposite sides of the two support plates. The inner wall of the threaded groove 6 is threadedly connected to the surface of the bidirectional stud 7, ensuring the stability of the rotation of the bidirectional stud 7. At the same time, the two positioning plates 4 will horizontally move relative to each other or away from each other simultaneously along with the rotation direction of the bidirectional stud 7.

[0017] The motor 8 is fixedly connected with a drive shaft through the output end on one side thereof. A gear 9 is fixedly installed at the center of the surface of the bidirectional stud 7 and at one end of the drive shaft respectively. The two gears 9 are vertically meshed and connected. Through the meshed connection of the two gears 9, the bidirectional stud 7 can be synchronously rotated when the motor 8 operates.

[0018] Connecting plates are fixedly connected to both sides of the upper end of the base 1. Guide rods are fixedly installed at the front and rear of the centers of the opposite sides of the two connecting plates. The opposite ends of the four guide rods arranged on both sides respectively penetrate outside the two positioning plates 4 and are fixedly connected to the opposite sides of the two support plates respectively, ensuring the smoothness of the horizontal movement of the positioning plate 4.

[0019] Sliding grooves 14 are opened at the tops of both sides of the inner wall of the installation groove. The two ends of the sliding plate 12 respectively extend into the two sliding grooves 14 and are slidably connected to the inner walls of the sliding grooves 14. The bottoms of the four connecting rods 13 respectively penetrate into the four installation grooves and are fixedly connected to the centers of the tops of the four sliding plates 12 respectively, making the pushing elastic plate 10 more stable when moving downward or bouncing under force.

[0020] A fixed frame 15 is fixedly installed on the top of the base 1. A cylinder is fixedly installed at the center of the inner top of the fixed frame 15. The cylinder is fixedly connected with a lifting plate through the output end at its bottom. A punching block is fixedly installed at the center of the bottom of the lifting plate. Rectangular grooves are opened on both sides of the top of the lifting plate. The inner diameter of the rectangular groove is larger than the outer diameter of the positioning plate 4. Guide grooves are opened at the positions near the top of both sides inside the fixed frame 15. The centers of both sides of the lifting plate are fixedly connected with guide sliders. The opposite ends of the two guide sliders respectively extend into the two guide grooves and are slidably connected to the inner walls of the guide grooves. The cylinder can drive the lifting plate to drive the punching block to move vertically, so as to realize the punching operation. At the same time, when the lifting plate moves vertically downward, due to the existence of the rectangular groove, it will not be blocked by the positioning plate 4.

[0021] First, place the steel plate to be stamped on the lower die 2 between the two positioning plates 4. Since the inner diameter of the groove 5 is larger than the outer diameter of the lower die 2, the two positioning plates 4 can move horizontally on the surface of the lower die 2. Then, start the motor 8. The output end of the motor 8 drives the drive shaft to rotate, and then drives the gear 9 meshed and connected vertically with it to rotate. Since the gear 9 is fixedly connected to the center of the bidirectional stud 7, the bidirectional stud 7 will also start to rotate. Since the thread grooves 6 on the two positioning plates 4 match the threads on both sides of the bidirectional stud 7, the two positioning plates 4 will move horizontally relative to or away from each other on the lower die 2 according to the rotation direction of the bidirectional stud 7, realizing the precise positioning of the steel plate. Next, after the steel plate is positioned, start the cylinder in the fixed frame 15. The cylinder drives the lifting plate to drive the stamping block at the bottom to move vertically downward to perform a stamping operation on the steel plate. The stamping block will enter the stamping groove 3 during the stamping process to process the steel plate. After the stamping is completed, the cylinder drives the lifting plate to drive the stamping block to rise and leave the stamping groove 3. At this time, since the steel plate exerts pressure on the material pushing elastic plate 10 inside the stamping groove 3 during the stamping process, the material pushing elastic plate 10 moves downward under the force, causing the connecting rod 13 at the bottom to contract into the installation groove and compress the material pushing spring 11 in the installation groove through the sliding plate 12. When the stamping block completely leaves the stamping groove 3, the material pushing spring 11 starts to reset, pushing the sliding plate 12 to rise, and then driving the material pushing elastic plate 10 to rise through the connecting rod 13, and pushing the stamped steel plate spring clamp out of the stamping groove 3 to achieve rapid material removal.

[0022] In summary, for this stamping die for leaf spring clamps, through the design of the positioning plate 4, threaded grooves 6, grooves 5, bi-directional studs 7, and motor 8, when the motor 8 is controlled to operate, it drives the gear 9 connected thereto to rotate, which in turn meshes with another gear 9 to drive the bi-directional stud 7 to rotate. Since the threaded grooves 6 on the two positioning plates 4 match the threads on both sides of the surface of the bi-directional stud 7, the two positioning plates 4 will move horizontally relative to or away from each other on the lower die 2 simultaneously according to the rotation direction of the bi-directional stud 7. This design enables the positioning of the steel plate during stamping, accurately positions steel plates of different lengths, and effectively avoids the problems of stamping deviation and increased scrap rate caused by inaccurate positioning. The design of the material pushing spring plate 10, material pushing spring 11, sliding plate 12, and connecting rod 13 is such that during the stamping process, when the sheet material deforms under force, it exerts pressure on the material pushing spring plate 10 inside the stamping groove 3, causing the material pushing spring plate 10 to move downward. During this movement, the connecting rod 13 at the bottom of the material pushing spring plate 10 will contract into the installation groove, simultaneously driving the sliding plate 12 to move together, and thus compressing the material pushing spring 11 in the installation groove. When the stamping is completed and the punching force on the sheet material disappears, the material pushing spring 11 starts to exert its reset function. Due to the elastic potential energy of the material pushing spring 11, it quickly pushes the sliding plate 12 upward, and then drives the material pushing spring plate 10 to rise together through the connecting rod 13. During this rising process, the material pushing spring plate 10 contacts and pushes the formed leaf spring clamp, enabling it to smoothly escape from the stamping groove 3, realizing the function of rapid material removal and improving the processing efficiency.
