Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for processing spacers. Background Technology
[0002] Stamping dies are special process equipment used in cold stamping to process metal or non-metal materials into parts or semi-finished products. Often called the "mother of industry," they are widely used in automobile manufacturing, electronics, aerospace, and other fields. Their structure consists of an upper die, a lower die, a punch, a die, a guide device, and other key components. The upper die moves with the press slide, while the lower die is fixed to the worktable. All components work together. The working principle is to use the power of the press to apply pressure to the blank, obtaining the desired stamped part through plastic deformation or separation of the material. They have advantages such as high production efficiency, stable quality, high material utilization, and low cost. According to the processing technology, they can be divided into blanking dies, bending dies, etc., corresponding to different processing steps. Today, stamping dies are developing towards higher precision and higher efficiency, providing strong support for modern industry.
[0003] For example, patent CN105057448A discloses a ring fastener stamping die, which includes a base plate, two supporting side plates, and a mounting plate. Two supporting shafts are installed between the two supporting side plates, and grooved rollers located between the two supporting side plates are installed on the supporting shafts. U-shaped grooves are opened on the supporting side plates, and a limiting block with a slot is fixed at the upper end of the supporting side plates. A pressure block that cooperates with the U-shaped groove is installed at the lower end of the mounting plate. The grooved workpiece is fitted into the slot of the limiting block and the groove of the grooved roller. However, when using existing equipment, due to the tight pressure between the spacer and the mold cavity and the lack of a separation mechanism, manual unloading is often required. Manual unloading not only increases labor intensity, but also easily causes deformation of the spacer due to improper operation. This not only affects the continuity of subsequent processing, but may also cause scratches on the surface of the spacer due to forced removal. In addition, the positioning structure of the mold is designed with fixed dimensions and cannot be flexibly adjusted according to the actual specifications of the spacer blank. This causes the blank to easily shift or shake during the stamping process, resulting in dimensional deviations such as hole diameter deviation and uneven wall thickness of the stamped spacer, which reduces the product qualification rate.
[0004] Therefore, in order to solve this problem, we propose a stamping die for the processing of spacers. Utility Model Content
[0005] The purpose of this utility model is to provide a stamping die for spacer processing, in order to solve the problems mentioned in the background art. When using the existing device, due to the tight pressure between the spacer and the die cavity, and the lack of a separation mechanism, manual unloading is often required. Manual unloading not only increases labor intensity, but also easily causes spacer deformation due to improper operation, which not only affects the continuity of subsequent processing, but may also cause scratches on the surface of the spacer due to forced removal. In addition, the positioning structure of the die is designed with fixed dimensions, which cannot be flexibly adjusted according to the actual specifications of the spacer blank. This causes the blank to easily shift or shake during the stamping process, resulting in dimensional deviations such as hole diameter deviation and uneven wall thickness of the stamped spacer, which reduces the product qualification rate.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for spacer processing, comprising a base plate, a first support column uniformly and fixedly connected to the top of the base plate, a first support plate fixedly connected to the top of the first support column, a first sliding groove formed in the middle of the top surface of the first support plate, a first double-threaded rod rotatably connected in the first sliding groove, a gear fixedly connected to the right end of the first double-threaded rod, a first slider threadedly connected to both ends of the first double-threaded rod, an inclined plate fixedly connected to the top of the first slider, a second support column uniformly and fixedly connected to the top of the first support plate, a second support plate fixedly connected to the top of the second support column, a circular groove formed in the top of the second support plate, a forming plate fixedly connected to the top of the top plate, circular blocks uniformly and fixedly connected to the bottom of the top plate, a sliding rod fixedly connected to the bottom of the circular blocks, a spring sleeved on the outer wall of the sliding rod, and a transmission roller fixedly connected to the bottom of the sliding rod.
[0007] Furthermore, a fixing rod is uniformly fixedly connected to the top of the base plate, a top template is fixedly connected to the top of the fixing rod, a cylinder is fixedly connected to the top template, a push rod is fixedly connected to the output end of the cylinder, a stamping plate is fixedly connected to the bottom of the push rod, and a stamping ring is fixedly connected to the bottom of the stamping plate.
[0008] Furthermore, a side block is fixedly connected to the middle of the outer right side wall of the stamping plate, a movable rod is fixedly connected to the bottom of the side block, and a rack is fixedly connected to the bottom of the movable rod.
[0009] Furthermore, a side plate is fixedly connected to the outer wall of the right side of the second support plate. A limiting groove is opened on the outer wall of the front of the side plate, and a limiting block is fixedly connected to the outer wall of the rear of the rack. The side plate and the rack are slidably connected through the limiting groove and the limiting block.
[0010] Furthermore, both ends of the outer walls on both sides of the stamping plate are fixedly connected to fasteners, and guide rods are movably connected to the fasteners. The top of the guide rods is fixedly connected to the top template, and the bottom of the guide rods is fixedly connected to the bottom plate.
[0011] Furthermore, a second sliding groove is provided on both sides of the top of the second support plate, and a second double-threaded rod is rotatably connected in the second sliding groove. Both ends of the second double-threaded rod are threadedly connected to a second slider, and a limit ring is fixedly connected to the top of the second slider.
[0012] Compared with the prior art, the beneficial effects of this utility model are: a stamping die for processing spacers adopts a novel structural design, the specific details of which are as follows:
[0013] (1) The stamping die for the spacer processing can automatically eject the spacer from the die cavity after stamping through the coordinated action of the side block, movable rod, rack, gear, first double thread rod, inclined plate, transmission roller, top plate and other components. It does not require manual assistance in unloading, avoids the deformation of the spacer caused by improper operation during manual unloading, and also prevents scratches on the surface of the spacer caused by forced removal, ensuring the quality of the spacer, reducing the intensity of manual labor, and improving the continuity of subsequent processing.
[0014] (2) The stamping die for the spacer processing has a second double threaded rod on both sides of the top of the second support plate that cooperates with the second slider and the limiting ring. The position of the limiting ring can be flexibly adjusted according to the actual specifications of the spacer blank, and the blank can be accurately limited and positioned. This effectively avoids the blank from shifting or shaking during the stamping process, reduces the dimensional deviations such as hole diameter shift and uneven wall thickness of the spacer after stamping, and improves the product qualification rate.
[0015] Furthermore, the fixing parts at both ends of the outer wall of the stamping plate cooperate with the guide rod to guide the up and down movement of the stamping plate, ensuring the stability and accuracy of the stamping plate's movement during the stamping process. The side plate and the rack are slidably connected to the limit block through the limit groove, ensuring the stability of the rack during the movement, thereby ensuring the reliable operation of the entire transmission process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] This utility model provides the following technical solution: a stamping die for processing spacers.
[0025] Example 1: A stamping die for processing spacers, through the coordinated action of components such as side block 13, movable rod 14, rack 15, and gear 211, causes the stamping plate 12 to move upward while driving the first double-threaded rod 21 to rotate. Then, through the threaded connection between the first double-threaded rod 21 and the first slider, the inclined plates 22 on both sides move horizontally relative to each other. Utilizing the inclined surface of the inclined plate 22 itself, the top plate 231 moves up and down via the transmission roller 24, thereby ejecting the stamped spacer. This prevents the spacer from being ejected due to the tight pressure between the spacer and the die cavity, which often requires manual unloading due to the lack of a separation mechanism. Manual unloading not only increases labor intensity but also easily causes spacer deformation due to improper operation, affecting the continuity of subsequent processing and potentially causing scratches on the spacer surface due to forced removal. Figure 1 - Figure 5As shown, a stamping die for processing spacers includes a base plate 1. A first support column is uniformly fixedly connected to the top of the base plate 1. A first support plate 2 is fixedly connected to the top of the first support column. A first groove is formed in the middle of the top surface of the first support plate 2. A first double-threaded rod 21 is rotatably connected within the first groove. A gear 211 is fixedly connected to the right end of the first double-threaded rod 21. First sliders are threaded to both ends of the first double-threaded rod 21. An inclined plate 22 is fixedly connected to the top of the first slider. A second support column is uniformly fixedly connected to the top of the first support plate 2. A second support plate 23 is fixedly connected to the top of the second support column. A circular groove is formed in the top of the second support plate 23. A top plate 231 is movably connected within the circular groove. A forming plate 232 is fixedly connected to the top of the top plate 231. Circular blocks are uniformly fixedly connected to the bottom of the top plate 231. A sliding rod is fixedly connected to the bottom of the circular blocks. A spring is sleeved on the outer wall of the sliding rod. A transmission roller is fixedly connected to the bottom of the sliding rod. 24. Fixed rods 11 are uniformly fixedly connected to the top of the base plate 1. A top template is fixedly connected to the top of the fixed rods 11. A cylinder is fixedly connected to the top template. A push rod is fixedly connected to the output end of the cylinder. A stamping plate 12 is fixedly connected to the bottom of the push rod. A stamping ring is fixedly connected to the bottom of the stamping plate 12. A side block 13 is fixedly connected to the middle of the right outer wall of the stamping plate 12. A movable rod 14 is fixedly connected to the bottom of the side block 13. A rack 15 is fixedly connected to the bottom of the movable rod 14. A side plate 16 is fixedly connected to the right outer wall of the second support plate 23. A limit groove is opened on the front outer wall of the side plate 16. A limit block is fixedly connected to the rear outer wall of the rack 15. The side plate 16 and the rack 15 are slidably connected to the limit block through the limit groove. Fixing members are fixedly connected to both ends of the outer walls on both sides of the stamping plate 12. A guide rod is movably connected to the fixing member. The top of the guide rod is fixedly connected to the top template. The bottom of the guide rod is fixedly connected to the base plate 1.
[0026] The cylinder on the top template is activated, and the output end of the cylinder pushes the push rod downward. The push rod drives the stamping plate 12 to move downward along the guide rod. The stamping ring at the bottom of the stamping plate 12 stamps the blank on the second support plate 23. At the same time as the stamping plate 12 moves downward, the side block 13 in the middle of its right outer wall drives the movable rod 14 and the rack 15 to move downward. At this time, the rack 15 and the gear 211 are in a non-meshing state, the first double thread rod 21 does not rotate, the position of the inclined plate 22 remains unchanged, and the top plate 231 is compressed by the spring through the slide rod under the pressure of the blank. The transmission roller 24 contacts the inclined plate 22. After the stamping is completed, the cylinder drives the push rod to move upward, and the push rod pulls the stamping plate 12 along the guide rod. The guide rod moves upward, and the stamping plate 12 drives the side block 13, the movable rod 14 and the rack 15 to move upward. When the rack 15 moves to mesh with the gear 211, the rack 15 drives the gear 211 to rotate. The gear 211 then drives the first double threaded rod 21 to rotate in the first groove of the first support plate 2. Since the two ends of the first double threaded rod 21 are threadedly connected to the first slider, the rotation of the first double threaded rod 21 causes the first sliders at both ends to drive the inclined plate 22 to move horizontally relative to each other. The inclined surface of the inclined plate 22 pushes the transmission roller 24 to move upward. The transmission roller 24 drives the top plate 231 to move upward through the slide rod. The forming plate 232 on the top of the top plate 231 pushes out the stamped spacer, realizing automatic unloading.
[0027] Example 2: Unlike Example 1, the threaded engagement between the second double-threaded rod 3 and the second slider allows the clamping rings at both ends of the second support plate 23 to move horizontally relative to each other. This limits and positions the spacer component, preventing the mold's positioning structure from being a fixed-size design that cannot be flexibly adjusted according to the actual specifications of the spacer blank. This would cause the blank to easily shift or wobble during stamping, resulting in dimensional deviations such as hole diameter shift and uneven wall thickness in the stamped spacer, thus reducing the product qualification rate. Figure 6 As shown, the second support plate 23 has second sliding grooves on both sides of its top. A second double threaded rod 3 is rotatably connected in the second sliding groove. Both ends of the second double threaded rod 3 are threadedly connected to a second slider. A limit ring is fixedly connected to the top of the second slider.
[0028] According to the specifications of the spacer blank, rotate the second double threaded rod 3. Since the two ends of the second double threaded rod 3 are threadedly connected to the second slider, and the top of the second slider is fixedly connected to the limit ring, the second slider will drive the limit ring to move relatively horizontally in the second groove at the top of the second support plate 23 until the limit ring firmly fixes the blank, thus completing the positioning of the blank.
[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
