Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping die guide, in particular to a high-elasticity and high-precision guide structure for stamping dies. Background Art
[0002] Stamping dies are widely used in industry. Stamping dies consist of an upper die and a lower die, which are installed on a press. Their working principle is generally to separate or plastically deform the raw materials between them by driving the upper die and the lower die to open and close under the action of the stamping power, so that the required parts can be processed.
[0003] In the existing technology, the position of the stamping die needs to be limited by guide pins when stamping. For stamping materials with a thickness greater than 0.15MM, the traditional structure has basically no problem. However, for thin materials with a thickness less than 0.15 and a large width, special material strips, and no guide blocks or stabilizing mechanisms in the lower die, the guide pin mode of the traditional structure will cause the material to be stripped unsmoothly, lift up the material strip, and cause the die to be unable to produce smoothly, resulting in low efficiency. In addition, during the stamping process, metal parts contact each other, which will cause loss between the device and the material strip, affecting the stamping effect. Utility Model Content

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a guiding structure for a stamping die with elastic high precision, including: an upper template 1, controllers 2 are fixedly installed at the four ends of the bottom of the upper template 1, the output ends of the controllers 2 are fixedly installed with telescopic rods 3, the other ends of the telescopic rods 3 are fixedly installed with a lower template 4, a housing 5 is fixedly installed at the top of the upper template 1, a first spring 6 is fixedly installed on the inner wall of the housing 5, a slide block 7 is installed inside the housing 5, a guide rod 8 is fixedly installed at the bottom of the slide block 7, and a first round hole 101 is opened on the surface of the upper template 1.
[0023] Specifically: when the device starts to be used, the controller 2 is started to shorten the telescopic rod 3, so that the upper template 1 descends, driving the guide rod 8 to descend, fixing the tape through the guide rod 8, and the elasticity of the first spring 6 enables the guide rod 8 to be adjusted when fixing, making the fixing more accurate, reducing errors, and making the device more perfect.
[0024] In one embodiment, restriction grooves 501 are opened on both sides of the inner wall of the housing 5, restriction blocks 701 are fixedly installed at both ends of the surface of the slide block 7, the surface of the restriction blocks 701 moves on the inner wall of the restriction groove 501, the bottom of the first spring 6 is fixedly installed on the top of the slide block 7, the surface of the slide block 7 moves on the inner wall of the housing 5, the surface of the guide rod 8 moves on the inner wall of the first round hole 101, and a tapered block 9 is installed at the bottom of the guide rod 8.
[0025] Specifically: When the device starts to be used, the lowering of the upper template 1 drives the guide rod 8 to lower. Through the restriction between the limiting blocks 701 fixedly installed on both sides of the slider 7 and the limiting grooves 501 opened on both sides of the inner wall of the housing 5, the slider 7 slides stably on the inner wall of the housing 5. According to the elasticity of the first spring 6, the guide rod 8 can correct the strip through the conical block 9 installed at the bottom of the guide rod 8, enabling the guide rod 8 to better stabilize the strip, reduce the offset during the stamping process, and make the device more perfect.
[0026] In one embodiment, circular grooves 10 are opened at the top of the upper template 1, and the number of circular grooves 10 is four. An activity hole 11 is opened at the bottom of the inner wall of the circular groove 10. A round rod 13 is movably embedded in the inner wall of the activity hole 11. A round block 12 is fixedly installed at the top of the round rod 13. The surface of the round block 12 is embedded in the inner wall of the circular groove 10. A second spring 1301 is sleeved on the surface of the round rod 13. A pressing plate 14 is fixedly installed at the bottom of the round rod 13. The bottom of the second spring 1301 is fixedly installed on the top of the pressing plate 14.
[0027] Specifically: When the device starts to be used, the telescopic rod 3 is started by the controller 2 to lower the upper template 1 for stamping the strip. During the stamping process, the pressing plate 14 will rise, causing the round rod 13 and the round block 12 at its top to rise. After stamping, the pressing plate 14 is restored by the elasticity of the second spring 1301. The pressing plate 14 is restored to its original position through the restriction of the round block 12. The stamped parts are removed through the reset of the pressing plate 14, making the device more perfect.
[0028] In one embodiment, a second round hole 1401 is opened on the surface of the pressing plate 14, and the inner wall of the second round hole 1401 is sleeved on the surface of the guide rod 8.
[0029] Specifically: During the stamping process, the surface of the guide rod 8 moves in the inner wall of the second round hole 1401. The strip is fixed and corrected by embedding the guide rod 8 into the limiting hole, making the device more perfect.
[0030] In one embodiment, a pressing block 15 is fixedly installed at the bottom of the pressing plate 14, and a protection block 16 is fixedly installed on the surface of the pressing block 15.
[0031] Specifically: The strip is stamped by the pressing block 15 fixedly installed at the bottom of the pressing plate 14. The strip and the pressing block 15 are protected by the protection block 16 fixedly installed on the surface of the pressing block 15 to reduce the contact between metals during the stamping process and reduce losses, making the device more perfect.
[0032] In one embodiment, a strip body 17 is fixedly installed at the top of the lower template 4. A guide hole 1701 is opened at the top of the strip body 17. A bottom plate 18 is installed at the top of the strip body 17. A guide groove 1801 is opened on the surface of the bottom plate 18.
[0033] Specifically: during the stamping process, after the conical block 9 installed at the bottom of the guide rod 8 is inserted into the guide hole 1701 and the guide groove 1801, as the upper template 1 continues to descend, it drives the guide rod 8 to be embedded. Through the elasticity of the first spring 6 and the shape of the conical block 9, the position of the strip body 17 is corrected, making the device more perfect.
[0034] Working principle: When the device starts to be used, the telescopic rod 3 is shortened by starting the controller 2, and the upper template 1 descends, driving the pressure plate 14 and the guide rod 8 to descend. The conical block 9 installed at the bottom of the guide rod 8 is embedded into the inner walls of the guide hole 1701 and the guide groove 1801. During the stamping process, the slider 7 at the top of the guide rod 8 slides stably on the inner wall of the limiting groove 501 opened on the inner wall of the housing 5 through the limiting block 701, making the device more stable during alignment. Through the shape of the conical block 9 and the elasticity of the first spring 6, the strip body 17 is aligned before stamping, enabling the guide rod 8 to be more closely embedded into the guide hole 1701 and the guide groove 1801, better aligning the strip body 17, resulting in a better stamping effect and higher precision. At the same time, during stamping, the pressure plate 14 will rise due to extrusion, and the round rod 13 and the round block 12 fixedly installed on the top of the pressure plate 14 will also rise accordingly. The round block 12 extends from the inner wall of the movable hole 11. After stamping is completed, the telescopic rod 3 is extended to drive the upper template 1 to rise. Through the elasticity of the second spring 1301, the pressure plate 14 is restored to its original position, and the round block 12 is restored into the inner wall of the movable hole 11. During the restoration process, the pressure plate 14 squeezes and removes the stamped part from the surface of the guide rod 8, making the device more perfect; during the stamping process, the protective block 16 fixedly installed on the surface of the pressing block 15 protects the strip body 17 and the pressing block 15, reducing the mutual contact between metal parts during stamping, reducing wear, making the stamping effect better, and making the device more perfect.
