[0007] Preferably, the lifting plate has a cavity inside one end, and two through holes are formed in the inner wall of the cavity.

[0011] Compared with related technologies, the clamping device for die steel blanking provided by this utility model has the following beneficial effects:

[0012] 1. By setting up columns, lifting structures, lifting plates, and translation structures, the mold steel can be accurately positioned in the vertical and horizontal directions through the coordinated operation of the lifting and translation structures. The first servo motor in the lifting structure drives the first threaded rod, which drives the lifting plate to accurately adjust its height. The second servo motor in the translation structure causes the bearing plate to achieve horizontal displacement through the transmission component, ensuring that the mold steel is in a precise processing position, effectively improving the blanking accuracy and reducing the scrap rate.

[0013] 2. By incorporating a support plate and a clamping structure, the clamping structure utilizes a design with two clamping plates and positive and negative threaded rods. Combined with rubber anti-slip pads on the clamping plates, it can provide a stable and uniform clamping force according to the size and shape of the mold steel. The rubber anti-slip pads not only increase the friction with the surface of the mold steel, preventing the mold steel from sliding during processing, but also effectively avoid damage to the surface of the mold steel, ensuring the surface quality of the mold steel. This eliminates the need for frequent manual adjustments to the position of the mold steel and the clamping force, effectively improving work efficiency. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The system includes: a base plate 1, a column 2, a lifting structure 3, a lifting plate 4, a translation structure 5, a bearing plate 6, and a clamping structure 7. The column 2 is fixedly connected to the upper surface of the base plate 1, providing a stable installation platform for the column 2. A groove is formed on the side surface of the column 2, and the lifting structure 3 is installed inside the groove. The column 2 serves as a vertical support structure, providing the installation position and movement track for the lifting structure 3. The lifting structure 3 includes a lifting block 8 and a first threaded rod 9. The lifting block 8 is slidably disposed inside the groove on the side surface of the column 2, and the groove on the side surface of the column 2 is used to limit the lifting... The movement trajectory of the lifting block 8 ensures that it moves up and down in a straight line. The lifting block 8 slides within the groove on the side surface of the column 2, achieving vertical movement. A threaded hole is provided on the upper surface of the lifting block 8, and a first threaded rod 9 is threadedly connected inside the threaded hole. When the first threaded rod 9 rotates, it connects with the threaded hole on the upper surface of the lifting block 8, allowing the lifting block 8 to rise and fall within the groove on the side surface of the column 2 in conjunction with the groove. A lifting plate 4 is provided on one side of the column 2, and one side of the lifting block 8 passes through the groove on the side surface of the column 2 and is fixedly connected to the outer surface of the lifting plate 4. During lifting, the lifting plate 4 can be raised and lowered. Two grooves are provided on the upper surface of the lifting plate 4. A translation structure 5 is installed inside each groove. The translation structure 5 includes a sliding block 10 and a second threaded rod 11. Two sliding blocks 10 are provided, each slidingly positioned inside one of the two grooves on the upper surface of the lifting plate 4. One end of each sliding block 10 has a threaded hole, and a second threaded rod 11 is threaded into each of the threaded holes. A bearing plate 6 is provided above the translation structure 5. The upper surfaces of the two sliding blocks 10 pass through the upper surface of the lifting plate 4. Two sliding grooves on the surface are fixedly connected to the lower surface of the support plate 6. When the sliding block 10 slides along the inside of the sliding groove on the upper surface of the lifting plate 4, it can drive the support plate 6 to move. The upper surface of the support plate 6 is provided with an installation groove. The installation groove on the upper surface of the support plate 6 is provided with a clamping structure 7. The clamping structure 7 includes a clamping plate 12 and a positive and negative threaded rod 13. Two clamping plates 12 are provided. The lower ends of the two clamping plates 12 are slidably set inside the installation groove on the upper surface of the support plate 6. The lower side surface of the two clamping plates 12 is provided with a threaded hole. The positive and negative threaded rod 13 is threadedly connected inside the threaded hole on the lower side surface of the two clamping plates 12.

[0023] In the specific implementation process, a first partition plate 14 is fixedly connected to the inner wall of the sliding groove on the side surface of column 2. A through hole is opened on the upper surface of the first partition plate 14. A first servo motor 15 is provided on the lower surface of the first partition plate 14. The outer surface of the first servo motor 15 is fixedly connected to the inner wall of the sliding groove on the side surface of column 2. The first servo motor 15 is electrically connected to an external power source. The lower end of the first threaded rod 9 passes through the through hole on the upper surface of the first partition plate 14 and is fixedly connected to the power output end of the first servo motor 15. The first threaded rod 9 can rotate inside the through hole on the upper surface of the first partition plate 14. The upper end of the first threaded rod 9 is rotatably connected to the top of the sliding groove on the side surface of column 2. When the first servo motor 15 is started, the power output end of the first servo motor 15 rotates and drives the first threaded rod 9 to rotate.

[0024] The lifting plate 4 has a cavity at one end, and two through holes are formed on the inner wall of the cavity. These two through holes communicate with two sliding grooves on the upper surface of the lifting plate 4. Two mounting plates 16 are fixedly connected to the bottom of the cavity. Each mounting plate 16 has a through hole on its side surface, and a transmission rod 17 is rotatably connected inside the through holes on the side surfaces of the two mounting plates 16. The two mounting plates 16 are used to mount the transmission rod 17, which can be mounted inside the through holes on the side surfaces of the two mounting plates 16. A second servo motor 18 is provided at the end. The bottom of the second servo motor 18 is fixedly connected to the bottom of the cavity of the lifting plate 4. The power output end of the second servo motor 18 is fixedly connected to one end of the transmission rod 17. The second servo motor 18 is electrically connected to an external power source. When the second servo motor 18 is started, the power output end of the second servo motor 18 rotates and drives the transmission rod 17 to rotate. Two transmission bevel gears 19 are fixedly connected to the outer surface of the transmission rod 17. When the transmission rod 17 rotates, it can synchronously drive the two transmission bevel gears 19 on the outer surface of the transmission rod 17 to rotate.

[0025] Among them, one end of each of the two second threaded rods 11 is rotatably connected to the inner wall of two grooves on the upper surface of the lifting plate 4, and the other end of each of the two second threaded rods 11 extends through two through holes in the inner wall of the cavity of the lifting plate 4. The two second threaded rods 11 can rotate inside the two through holes in the inner wall of the cavity of the lifting plate 4. One end of each of the two second threaded rods 11 extending into the cavity of the lifting plate 4 is fixedly connected to a driven bevel gear 20. The driven bevel gear 20 at the end of each of the two second threaded rods 11 located in the cavity of the lifting plate 4 meshes with two transmission bevel gears 19 on the outer surface of the transmission rod 17. When the two transmission bevel gears 19 rotate, they mesh and simultaneously drive the driven bevel gear 20 to rotate. When the driven bevel gear 20 rotates, it drives the two second threaded rods 11 to rotate synchronously.

[0026] A second partition plate 21 is fixedly connected to the inner wall of the mounting groove on the upper surface of the support plate 6. A third servo motor 22 is installed on one side of the second partition plate 21. The bottom of the third servo motor 22 is fixedly connected to the bottom of the mounting groove on the upper surface of the support plate 6. The third servo motor 22 is electrically connected to an external power supply. A through hole is opened on the side surface of the second partition plate 21. A positive and negative threaded rod 13 is rotatably connected to the inside of the through hole on the side surface of the second partition plate 21. One end of the positive and negative threaded rod 13 is fixedly connected to the power output end of the third servo motor 22. The third servo motor 22 is activated, and the power output end of the third servo motor 22 rotates, which drives the positive and negative threaded rod 13 to rotate. The other end of the positive and negative threaded rod 13 is rotatably connected to the inner wall of the mounting groove on the upper surface of the bearing plate 6. The positive and negative threads of the positive and negative threaded rod 13 are respectively located inside the threaded holes on the lower side surface of the two clamping plates 12. When the positive and negative threaded rod 13 rotates, the positive and negative threads on the outer surface of the positive and negative threaded rod are respectively threadedly connected to the threaded holes on the lower side surface of the two clamping plates 12, so that the two clamping plates 12 slide towards each other or away from each other.

[0027] The mold steel body 23 is placed between the two clamping plates 12. The lower surface of the mold steel body 23 is attached to the upper surface of the support plate 6. The two clamping plates 12 slide in the mounting groove on the upper surface of the support plate 6 to achieve clamping and loosening operations on the mold steel body 23. Rubber anti-slip pads 24 are fixedly connected to the opposite side of the two clamping plates 12. The rubber anti-slip pads on the opposite side of the two clamping plates 12 are attached to the outer surface of the mold steel body 23. The rubber anti-slip pads 24 increase the friction with the mold steel body 23, prevent the mold steel body 23 from sliding, and avoid damage to the surface of the mold steel body 23.

[0028] The working principle of this utility model is as follows: The base plate 1 provides stable support, and the column 2 is installed on the base plate 1 as a vertical support structure. When the operator places the mold steel, the mold steel is first placed between the two clamping plates 12. The third servo motor 22 is started, and the power output end of the third servo motor 22 rotates and drives the positive and negative threaded screws 13 to rotate. Since the positive and negative threads of the positive and negative threaded screws 13 are respectively engaged with the threaded holes at the lower end of the two clamping plates 12, the rotation of the positive and negative threaded screws 13 causes the two clamping plates 12 to move in opposite directions within the mounting groove of the bearing plate 6. The clamping of the mold steel body 23 is achieved. The rubber anti-slip pad 24 increases the friction between the clamping plate 12 and the mold steel body 23, preventing the mold steel from sliding during processing and protecting its surface. The operator starts the first servo motor 15, and the power output end of the first servo motor 15 rotates and drives the first threaded rod 9 to rotate. Since the lifting block 8 is connected to the first threaded rod 9 through the threaded hole and slides in the slide groove of the column 2, the rotation of the first threaded rod 9 causes the lifting block 8 to move linearly up and down along the slide groove of the column 2, thereby driving the lifting plate 4 connected to the lifting block 8. To achieve vertical position adjustment, the bearing plate 6 is adjusted to a suitable processing position on the processing machine. The second servo motor 18 is started, and the power output end of the second servo motor 18 rotates, driving the transmission rod 17 to rotate. When the transmission bevel gear 19 on the transmission rod 17 rotates, it meshes with the driven bevel gear 20 at one end of the second threaded rod 11, driving the driven bevel gear 20 to rotate. When the driven bevel gear 20 rotates, it drives the second threaded rod 11 to rotate synchronously. The sliding block 10 is connected to the second threaded rod 11 through a threaded hole and slides in a groove on the upper surface of the lifting plate 4. The sliding block 10 slides internally, which drives the bearing plate 6 to move horizontally, making it easy to move the bearing plate 6 to a suitable processing position on the processing machine. When the mold steel is finished and unloaded, the second servo motor 18 and the first servo motor 15 are controlled to reverse their power output ends in sequence, so that the bearing plate 6 is reset. The third servo motor 22 is controlled to drive the positive and negative threaded rods 13 to reverse. The reverse rotation of the positive and negative threaded rods 13 causes the two clamping plates 12 to move in opposite directions in the mounting groove of the bearing plate 6, thereby releasing the mold steel body 23 and completing the unloading of the mold steel body 23.
