[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts.
[0003] The adjustment sliders used in existing stamping dies all have spring resets installed inside the sliders. Due to the limitations of the size of the position, the length and elasticity of the springs used are relatively small. During the mold production process, the springs are prone to fatigue and untimely reset, resulting in unstable product dimensions. The springs need to be replaced frequently. Therefore, a high-speed and large-stroke bending slider adjustment structure is proposed. Utility Model Content

[0028] Example
[0029] In the prior art, the adjustment sliders used in the existing stamping dies are all equipped with spring reset inside the sliders. Due to the limitations of the size of the position, the length and elasticity of the springs used are relatively small. During the mold production process, the springs are prone to fatigue and untimely reset, resulting in unstable product dimensions and the high frequency of spring replacement.
[0030] See also Figure 1-7 The utility model provides a technical solution: a high-speed and large-stroke bending slider adjustment structure, including an adjusting rod 1, the adjusting rod 1 is installed at the bottom of the upper pad of the stamping die, the assembly gap between the adjusting rod 1 and the upper pad is 0.02 mm on one side, and they slide with each other. A support rod 2 is arranged at the lower side of the adjusting rod 1, and the support rod 2 is installed at one side of the upper clamping plate of the stamping die. The assembly gap between the support rod 2 and the upper clamping plate is 0.01 mm on one side, and they slide with each other. A longitudinal slider 3 is connected to the bottom of the support rod 2, and the longitudinal slider 3 is installed at one side of the lower template of the stamping die. The assembly gap between the longitudinal slider 3 and the lower template is 0.005 mm, and they slide with each other precisely. A transverse slider 4 is arranged on one side of the longitudinal slider 3, and the transverse slider 4 is installed at the top of the lower template of the stamping die. The assembly gap between the transverse slider 4 and the lower template is 0.001 mm, and they slide with each other.
[0031] An adjustment block 5 for bending parts is installed on one side of the transverse slider 4, and the adjustment block 5 is tightly fitted with the limit groove 11. An insert 6 is arranged on one side of the adjustment block 5, and the insert 6 is installed on the side of the lower template of the stamping die. The assembly gap between the insert 6 and the lower template is 0.002 mm, and they are slightly tight fit with each other. The lower side of the longitudinal slider 3 is connected with a first force transmission pin 7, and the first force transmission pin 7 is installed on one side of the lower pad. The assembly gap between the first force transmission pin 7 and the lower pad is 0.05 mm, and they are loosely fit with each other. The second force transmission pin 8 is installed on one side of the lower die base, and the assembly gap between the second force transmission pin 8 and the lower die base is 0.1 mm, and they are loosely fit with each other. The lower side of the first force transmission pin 7 is connected with a second force transmission pin 8, and the lower side of the second force transmission pin 8 is connected with a spring 9, which is installed on one side of the lower die base. The top side of the transverse slider 4 is slidably connected with a pressure plate 10, and the pressure plate 10 is fixed to the top of the lower template by bolts.
[0032] In order to ensure the sliding stability of the transverse slider 4, an inclined slider 12 is integrally formed on one side of the longitudinal slider 3, and a limiting groove 11 and an inclined sliding groove 13 are respectively provided on one side of the transverse slider 4. The spacing between the pressure plate 10 and the transverse slider 4 is 0.01 mm. After the pressure plate 10 is tightened by bolts, the transverse slider 4 can move back and forth smoothly. The outer side of the inclined slider 12 is obliquely slidably connected to the inner side of the inclined sliding groove 13, and is used to push the transverse slider 4 to move horizontally when the longitudinal slider 3 moves downward.
[0033] In order to perform bending processing on different parts, the outer side of the adjustment block 5 is installed on the inner side of the limit groove 11, and one side of the insert 6 is adapted to one side of the adjustment block 5. The adjustment block 5 and the insert 6 perform bending adjustment or forming actions on the parts. At the same time, when bending different parts, the adjustment blocks 5 and inserts 6 of different structures can be replaced, and the parts can be bent into different shapes.
[0034] A first inclined surface 15 is provided on one side of the bottom of the adjusting rod 1, and a screw hole 14 is opened on one side of the adjusting rod 1. A bolt is threadedly connected to the inner side of the screw hole 14. A second inclined surface 16 is provided on one side of the top of the support rod 2. By turning the bolt, the bolt is threadedly connected to the screw hole 14, and the bolt is threadedly connected to the upper clamping plate. The relative position of the adjusting rod 1 and the upper pad can be adjusted. At this time, the first inclined surface 15 slides on different lengths of the second inclined surface 16. At this time, the up and down movement distance of the support rod 2 can be controlled, and then the front and back movement distance of the transverse slider 4 can be controlled. The gap between the transverse slider 4 and the pressure plate 10 is 0.01 mm, thereby controlling the contact distance between the adjustment block 5 and the part, so as to adjust the size and angle of the part. Simply adjusting the position of the bolt in the screw hole 14 can quickly change the up and down movement distance of the support rod 2, thereby adapting to the adjustment requirements of different part sizes and angles.
[0035] Working principle: when the stamping die is stamping the parts, the support rod 2 moves downward with the stamping upper die, and when the lower side of the support rod 2 contacts the top of the longitudinal slider 3, the longitudinal slider 3 moves downward. When the longitudinal slider 3 moves downward, the inclined slider 12 is driven to move downward. At this time, the inclined slider 12 slides inside the inclined slide groove 13. At this time, the inclined slide groove 13 drives the transverse slider 4 to drive the adjustment block 5 to move toward the side of the insert 6. At this time, the adjustment block 5 and the insert 6 perform bending adjustment or forming actions on the parts. At the same time, when bending different parts, the adjustment blocks 5 and inserts 6 of different structures can be replaced. At this time, the parts can be bent into different shapes. The coordinated work among the support rod 2, the longitudinal slider 3, the inclined slider 12, the inclined slide groove 13, the transverse slider 4, the adjustment block 5 and the insert 6 ensures the accurate bending or forming of the parts. The adjustment blocks 5 and inserts 6 of different structures can be replaced. The mold can adapt to the bending requirements of different parts, so that the same set of molds can be used to produce parts of various shapes, reducing the production cost and the frequency of mold replacement.
[0036] When the support rod 2 finishes moving downward, the support rod 2 is driven by the upper stamping die to move upward. At this time, the elastic force of the spring 9 pushes the first force transmission pin 7 and the second force transmission pin 8 to move upward respectively. At this time, the first force transmission pin 7 and the second force transmission pin 8 push the longitudinal slide block 3 to move upward, and at the same time, the inclined slide block 12 on one side of the longitudinal slide block 3 slides inside the inclined slide groove 13, so that the transverse slide block 4 moves to its original position for the next bending of the part. In this process, the spacing between the pressure plate 10 and the transverse slide block 4 is 0.01 mm. After the pressure plate 10 is locked by bolts, the transverse slide block 4 can move back and forth smoothly, and at the same time prevent the transverse slide block 4 from jumping up and down when sliding. When this structure is applied to a stamping die with high speed and large stroke, the two slide blocks of the longitudinal slide block 3 and the transverse slide block 4 are used, and the spring 9 is installed on the bottom die seat, so that the length and elastic force of the spring 9 are no longer limited by space, which reduces the problem that the spring 9 is prone to fatigue and reset in time, resulting in the phenomenon that the size of the part is prone to instability, etc., causing the problem of high frequency of replacement of the spring 9;
[0037] During high-speed stamping, the length and elastic force of the spring 9 are no longer limited, and its working state is more stable, reducing fatigue caused by frequent expansion and contraction. Accurate resetting and stable sliding action ensure the continuity and efficiency of the mold, ensuring that the spring 9 can stably provide elastic force during high-speed stamping, achieving accurate resetting of the longitudinal slider 3 and the transverse slider 4, and helping to reduce problems such as unstable part size caused by inaccurate resetting.
[0038] When it is necessary to adjust the up and down movement distance of the support rod 2, it is only necessary to rotate the bolt inside the screw hole 14 so that the adjustment rod 1 is at different positions on the upper side of the support rod 2. At this time, the first inclined surface 15 slides on the second inclined surface 16 at different lengths. At this time, the up and down movement distance of the support rod 2 can be controlled, and then the front and rear movement distance of the horizontal slider 4 can be controlled, thereby controlling the contact distance between the adjustment block 5 and the part, so as to adjust the size and angle of the part. Simply adjusting the position of the bolt in the screw hole 14 can quickly change the up and down movement distance of the support rod 2, thereby adapting to the adjustment needs of different part sizes and angles, so that the stamping die can quickly adapt to changes in the production line, thereby improving production efficiency and flexibility.
