DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0019] like Figure 1 to Figure 11As shown, this embodiment proposes a uniform force fixing device for processing metal rolled workpieces, including a clamping chassis 1, a clamping assembly 53 is fixedly arranged on the top of the clamping chassis 1, the clamping assembly 53 includes a support frame 2, a clamping cylinder 4 is fixedly installed on one side of the support frame 2, the output end of the clamping cylinder 4 is fixedly connected to a cylinder push rod 5, one side of the cylinder push rod 5 is fixedly connected to a moving seat 6, two symmetrically arranged slide rails 7 are arranged on the top of the support frame 2, a slide seat 8 is slidably connected to the slide rail 7, and the two slide seats 8 are fixedly connected to the bottom of the moving seat 6, and the top of the support frame 2 is fixedly connected to two symmetrically arranged slide rails 12, a slide seat 13 is slidably connected to the slide rail 12, and a moving seat 14 is fixedly connected to the top of the two slide seats 13. The flexibility and adaptability of clamping are significantly improved by setting structures such as the clamping assembly 53. First, the moving seat is driven by the cylinder push rod 5, and then the synchronous rod system is driven, so as to realize the function of accurately adjusting the clamp in advance according to the size of the workpiece. During the clamping process, the device design allows the chuck to be adaptively adjusted when facing irregular-shaped workpieces, ensuring that the three chucks can apply uniform force to the edge of the workpiece, which not only ensures the firmness of the clamping, but also avoids damage to the workpiece. After the clamping is completed, efficient rolling operation can be carried out. Compared with the traditional clamping device, this embodiment has made significant progress in clamping stability and workpiece protection, which not only improves the accuracy and efficiency of rolling processing, but also effectively reduces the risk of workpiece damage caused by improper clamping. Therefore, this embodiment provides a more reliable, efficient and practical solution for the rolling processing of metal workpieces.

[0020] like Figure 1 to Figure 11 As shown, the tops of slide 2 13 and slide 1 8 are respectively fixedly connected with clamping seats 15, and a rotating seat 11 is rotatably installed inside the support frame 1 2. A main synchronization rod 10 is fixedly sleeved on the outer circumference of the rotating seat 11, and one end of a secondary synchronization rod 9 is movably hinged at both ends of the main synchronization rod 10, and the other ends of the two secondary synchronization rods 9 are respectively movably hinged on the two clamping seats 15.

[0021] like Figure 1 to Figure 11 As shown, an electric lead screw 16 is installed on the top of the clamping seat 15, and a lead screw 17 is arranged inside the electric lead screw 16. One side of the lead screw 17 is fixedly connected to a chuck fixing seat 19, and one side of the chuck fixing seat 19 is fixedly connected to two symmetrically arranged limit seats 18. The top of the clamping seat 15 is fixedly connected to two symmetrically arranged limit blocks, and the limit blocks are slidably connected to the inside of the limit seat 18.

[0022] like Figure 1 to Figure 11As shown, a clamping quick-release plate 20 is installed on one side of the clamp fixing seat 19, and two symmetrically arranged hinged blocks 21 are fixedly connected to one side of the clamping quick-release plate 20, and a hinged rod 23 is movably hinged inside the hinged block 21, and two symmetrically arranged movable fixing seats 22 are fixedly connected to one side of the clamping quick-release plate 20, and a hinged block 2 35 is slidably assembled inside the movable fixing seat 22, and a hinged rod 2 24 and a hinged rod 3 26 are movably hinged inside the hinged block 2 35, respectively, a clamp 1 25 is movably hinged between the hinged rod 1 23 and the hinged rod 2 24, and a clamp 2 27 is movably hinged between the hinged rod 24 and the hinged rod 3 26.

[0023] In this embodiment, the process of using this device to perform rolling treatment on a metal workpiece is as follows: First, the clamping cylinder 4 is started according to the size of the workpiece. The start of the clamping cylinder will drive the cylinder push rod 5 to move forward, and then push the moving seat 1 6 to move outward. While the moving seat 1 6 moves outward, it will drive the auxiliary synchronous rod 9 that is hinged on it to move together. The rotation of the auxiliary synchronous rod 9 will further drive the main synchronous rod 10 to rotate with the rotating seat 11 as the center. The rotation of the main synchronous rod 10 will simultaneously drive the moving seat 2 14 to move in the symmetrical direction of the moving seat 1 6 through another auxiliary synchronous rod 9, so as to accurately adjust the clamp in advance according to the size of the workpiece; After adjusting to the appropriate position, the two electric lead screws 16 are further started at the same time, and the lead screws 17 on both sides will move synchronously toward the direction of the middle workpiece, driving the two chucks 1 25 and the chuck 2 27 to move simultaneously, so as to firmly clamp the workpiece. During the clamping process, since the hinge block 2 35 is slidably connected to the inside of the movable fixed seat 22, when clamping workpieces with irregular shapes on both sides, for example, when the workpiece is wider in the middle, the chuck 2 27 will move backward, and the two chucks 1 25 will move forward, so that the three chucks can well apply uniform force to the edge of the workpiece. This design ensures that adaptive adjustment is performed while the clamping is firm and no damage is caused to the workpiece, ensuring excellent clamping effect and providing uniform rolling guarantee for subsequent rolling processing; After clamping is completed, the calendering operation can be carried out. The entire calendering process adopts the existing technology and will not be repeated here. It is worth mentioning that this embodiment not only improves the flexibility and adaptability of clamping, but also significantly improves the accuracy and efficiency of the calendering process, reduces the risk of workpiece damage caused by improper clamping, and has significant beneficial effects. Compared with traditional clamping devices, this embodiment has made significant progress in clamping stability and workpiece protection, and provides a more reliable and efficient solution for the calendering processing of metal workpieces. Example 2

[0024] like Figure 1 to Figure 11As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a replacement component 54, which includes a slider 52. A slide groove 28 is provided inside the clamping quick-release plate 20. The slider 52 is slidably connected inside the slide groove 28. A limiting groove 29 is provided inside the slide groove 28. The limiting groove 29 is slidably connected to a limiting rod 30. A clamping block 31 is fixedly connected to one side of the limiting rod 30. The bottom of the clamping block 31 is inclined. By setting the replacement component 54 and other structures, the corresponding size of the chuck can be easily selected and replaced, which greatly simplifies the chuck replacement process, enables the device to quickly adapt to the holding needs of workpieces of different sizes, and significantly improves the versatility of the fixing device. At the same time, the firm fixation of the new chuck ensures stability and safety during the processing, helps to improve processing efficiency and workpiece quality. Compared with the traditional fixing device, it not only improves the convenience of operation, but also realizes efficient processing of different workpieces by quickly replacing the chuck.

[0025] like Figure 1 to Figure 11 As shown, a receiving groove 33 is provided inside the clamping quick-release plate 20, and a return spring 34 is fixedly connected between the receiving groove 33 and the clamping block 31. The return spring 34 is sleeved on the outer circumferential surface of the limiting rod 30, and a clamping groove 32 is provided inside the chuck fixing seat 19. The shapes and sizes of the clamping block 31 and the clamping groove 32 are the same.

[0026] In this embodiment, when rolling and pressing workpieces of different specifications, the chuck of corresponding size can be easily selected and replaced according to the specific size of the workpiece, and the operation process is as follows: first, the two sliders 52 are pulled up at the same time. During the rising process of the sliders 52, the two limit rods 30 will move along the direction of the limit groove 29 through the setting of the limit groove 29, and this movement will synchronously drive the clamping block 31 to move, and finally the clamping block 31 will be smoothly moved from the inside of the clamping groove 32 to the storage groove 33, thereby releasing the fixed relationship between the chuck fixing seat 19 and the supporting quick release plate. At this time, the original chuck can be easily removed upwards, and a new chuck with a more suitable size can be taken out for replacement; When replacing a new chuck, just align the two blocks 31 with the positions of the two slots 32 respectively, and then insert it downward. Since the bottom of the block 31 is designed to be inclined, during the downward pressing process, the blocks 31 on both sides will move toward the middle into the receiving slot 33 until they are aligned with the slot 32. At this time, under the strong action of the return spring 34, the block 31 will be ejected into the slot 32, completing the firm fixation of the new chuck; By easily replacing chucks of different sizes, the device can easily meet the holding needs of workpieces of different sizes, significantly improving the versatility and flexibility of the fixture. Compared with traditional fixtures, this embodiment not only greatly simplifies the chuck replacement process, but also significantly improves processing efficiency and workpiece quality. This innovative design undoubtedly provides a more efficient and convenient solution for the rolling processing of metal workpieces. Example 3

[0027] like Figure 1 to Figure 11 As shown, based on the same concept as the above-mentioned embodiments 1 and 2, this embodiment further proposes a material return assembly 36, which includes a top block 47, a support frame 2 3 is fixedly connected to the top of the clamping chassis 1, a top groove 48 is provided inside the support frame 2 3, the top block 47 is slidably connected to the inside of the top groove 48, the top of the top block 47 is inclined, and a plurality of lifting springs 49 uniformly distributed in a rectangular array are fixedly connected between the top groove 48 and the top block 47, a sliding groove 50 is provided inside the support frame 2 3, a connecting plate 51 is slidably connected inside the sliding groove 50, one side of the connecting plate 51 is fixedly connected to one side of the top block 47, and the bottom of the connecting plate 51 is fixedly connected to the moving rack 46, and automatic material unloading is realized by setting structures such as the material return assembly 36. During the process, the movement of the supporting seat drives the fixed rack 38, which then rotates through the linkage gear and the synchronous belt 41, and finally drives the driven bevel gear 43 and the lifting gear 45 to rotate. This series of actions causes the moving rack 46 to move upward, and then drives the top block 47 to move upward through the connecting plate 51, and pushes the workpiece forward and upward, achieving the effect of convenient unloading, which not only simplifies the unloading process, but also significantly improves work efficiency and safety. Compared with the traditional manual unloading method, the automated unloading design of this embodiment reduces the labor intensity of workers, avoids the safety risks that may be caused by manual operation, and improves production efficiency at the same time, providing a more efficient and safe solution for the rolling processing of metal workpieces, and has significant practical application value.

[0028] like Figure 1 to Figure 11 As shown, a fixed rack 38 is fixedly connected to the bottom of the clamping seat 15, and a support shaft 1 39 and a support shaft 2 40 are rotatably installed inside the support frame 2 3, and a linkage gear 1 37 is provided on the outer peripheral surface of the support shaft 1 39 through a one-way bearing sleeve, and the linkage gear 1 37 and the fixed rack 38 are meshingly connected. A synchronous belt 41 is provided between the support shaft 1 39 and the support shaft 2 40 through a synchronous wheel sleeve, and a driving bevel gear 42 is fixedly sleeved on the outer peripheral surface of the support shaft 2 40, and a driven shaft 44 is rotatably installed inside the support frame 2 3, and a lifting gear 45 and a driven bevel gear 43 are respectively sleeved on the outer peripheral surface of the driven shaft 44, and the driven bevel gear 43 and the driving bevel gear 42 are meshingly connected, and the lifting gear 45 and the moving rack 46 are meshingly connected.

[0029] In this embodiment, after the rolling work is completed, the holding cylinder is started to perform the reset operation. At this time, the clamping cylinder 4 is started and drives the holding seat to move to both sides, and at the same time drives the fixed rack 38 to move together. The movement of the fixed rack 38 further triggers the rotation of the linkage gear meshing with it. Through the transmission of the synchronous belt 41, the linkage gear drives the rotation of the supporting shaft 2 40. While the supporting shaft 2 40 is rotating, it drives the rotation of the active bevel gear 42, and finally drives the rotation of the active bevel gear 42 to further drive the rotation of the driven bevel gear 43 meshing with it. When the driven bevel gear 43 rotates, it also drives the driven shaft 44 and the lifting gear 45 to rotate. The rotation of the lifting gear 45 drives the moving rack 46 to move upward. When the moving rack 46 moves upward, it drives the ejector block 47 to move upward through the connecting plate 51, thereby ejecting the workpiece forward and upward, achieving the effect of convenient material unloading, which not only simplifies the unloading process, but also improves work efficiency and safety. After the unloading is completed, with the reset of the supporting seat, the top block 47 is driven to reset through the transmission system, preparing for the next rolling work. Compared with the traditional manual unloading method, the automated unloading design of this embodiment not only reduces the labor intensity of the workers, but also improves production efficiency and safety.
