[0002] Rare earth metals are a group of 17 elements in the IIIB group of the periodic table, which have strong chemical activity and unique physical properties. Rare earth metals are usually extracted in bulk form, and downstream industries require rare earth metal blocks of different sizes. Therefore, it is necessary to process the bulk rare earth metals into metal strips or small-sized metal blocks through a shearing device to meet the application needs of different industries. The cutting device of rare earth metals is a device specially used for efficient and precise cutting of rare earth metals. It usually includes support beams, base plates, knife frames, and cutting components. It can improve production efficiency and meet different production needs through multi-dimensional cutting technology.

[0003] Existing metal shearing devices usually use the following process flow to shear rare earth metal sheets: First, the rare earth metal sheet to be processed is firmly fixed on a special fixture to ensure its stability during the shearing process.

During the shearing process, the shearing tool rotates at a preset speed and angle to accurately cut the metal sheet. After each cutting operation, the fixture position needs to be readjusted in order to proceed to the next round of shearing operations.

When the output end of the hydraulic cylinder 3 is extended, the output end of the hydraulic cylinder 3 drives the screw 24 to rotate through the linkage assembly. When the screw 24 rotates, it drives the slide 16 to move toward the direction close to the gantry 2. When the slide 16 moves, it drives the rare earth metal plate inside the clamp 9 to move through the connecting plate 15. After the movement is completed, the shearing knife 6 of the shearing mechanism contacts the rare earth metal plate, and then the rare earth metal plate can be sheared. By linking the transmission mechanism with the shearing mechanism, the rare earth metal plate moves a certain distance every time the output end of the hydraulic cylinder 3 is extended and retracted, and the shearing knife 6 performs a shearing, thereby shearing a rare earth metal plate of a fixed length, thereby improving the shearing accuracy.

[0025] In this embodiment, preferably, a support plate 32 is fixedly installed on the inner side of the gantry 2, a support rod 33 is fixedly installed on the top side of the support platform 1 away from the gantry 2, and both ends of the screw rod 24 are rotatably connected to the support plate 32 and the support rod 33 respectively, thereby supporting the screw rod 24.

[0026] In this embodiment, preferably, the shearing mechanism includes a knife seat 5, a shearing knife 6 and a connecting seat 7, the connecting seat 7 is fixedly connected to the support platform 1, one end of the knife seat 5 is rotatably connected to the connecting seat 7, the shearing knife 6 is fixedly installed below the knife seat 5, the output end of the hydraulic cylinder 3 is installed with a hinge 4, the output end of the hydraulic cylinder 3 is hinged to one end of the knife seat 5 through the hinge 4, the support platform 1 is provided with a knife groove below the shearing knife 6, so that the shearing knife 6 can be extended into the knife groove during shearing, so as to facilitate the shearing of rare earth metals, and the knife seat 5 can be driven to rotate by the extension and retraction of the output end of the hydraulic cylinder 3, thereby driving the shearing knife 6 to rotate for shearing.

[0027] In this embodiment, preferably, the linkage assembly includes a driving wheel 27, a driven wheel 25, a gear 30, a rack 31, a one-way bearing 29, a connecting shaft 26 and a transmission belt 28. The connecting shaft 26 is rotatably connected to the support plate 32. The connecting shaft 26 is fixedly sleeved with a driving wheel 27, and one end of the screw rod 24 is fixedly sleeved with a driven wheel 25. The driving wheel 27 and the driven wheel 25 are transmission-connected by a transmission belt 28. A gear 30 is sleeved on the connecting shaft 26. The rack 31 is unidirectionally transmission-connected to the connecting shaft 26 through a one-way bearing 29. The bottom end of the rack 31 is fixedly connected to the top of the hinge 4, and the rack 31 is adapted to the gear 30. When the rack 31 is meshed with the gear 30 and the rack 31 moves downward, the rack 31 drives the gear 30 to rotate. When the gear 30 rotates, the one-way shaft The bearing 29 drives the connecting shaft 26 to rotate. When the connecting shaft 26 rotates, the driven wheel 25 is driven to rotate through the driving wheel 27 and the transmission belt 28, thereby driving the screw 24 to rotate, thereby driving the slide 16 to move in the direction close to the gantry 2. When the shearing knife 6 is about to contact the rare earth metal plate, the rack 31 is separated from the gear 30, so that the slide 16 stops moving, thereby stopping the movement of the rare earth metal plate to avoid affecting the shearing of the rare earth metal plate. After the shearing is completed, the output end of the hydraulic cylinder 3 contracts, thereby driving the rack 31 to move upward through the hinge 4. When the rack 31 is engaged with the gear 30, the gear 30 rotates in the opposite direction. At this time, the rotation of the gear 30 only drives the outer ring of the one-way bearing 29 to rotate, and the inner ring of the one-way bearing 29 does not rotate, so that the connecting shaft 26 does not rotate, and then the clamp 9 does not move.

[0028] In this embodiment, preferably, a through slot 201 is provided on the gantry 2 , and the through slot 201 is located directly above the rack 31 . When the rack 31 moves upward, the rack 31 passes through the through slot 201 , thereby preventing the rack 31 from hitting the gantry 2 .

[0029] In this embodiment, preferably, the clamp 9 is a concave structure, and the two opposite inner sides of the clamp 9 are symmetrically provided with clamps 11, and the clamps 11 are L-shaped structures. Two slide grooves are provided on the clamp 9, and a slide plate 12 is fixedly installed on one side of the two clamps 11. The two slide plates 12 are slidably connected with the two slide grooves respectively. A tension spring 13 is provided inside the slide groove, and the slide plate 12 is elastically connected with the inner side wall of the slide groove through the tension spring 13. Under the action of the tension spring 13, after the roller 14 is separated from the driving block 35, the two clamps 11 can approach each other to close the gap between the two clamps 11 The rare earth metal plate is fixed, and a roller 14 is rotatably installed on one end of the slide plate 12 away from the clamp 11. Two driving blocks 35 are fixedly installed on the side of the top of the support platform 1 away from the gantry 2. An inclined surface is provided on one side of the driving block 35. When the clamp 9 moves in a direction away from the gantry 2, the clamp 9 drives the slide plate 12 and the roller 14 to move. When the roller 14 contacts the inclined surface of the driving block 35, as the clamp 9 continues to move, the two rollers 14 move away from each other under the action of the inclined surface of the driving block 35, thereby releasing the fixation of the rare earth metal plate in the clamp 9.

[0030] In this embodiment, preferably, both ends of the clamp 9 are fixedly installed with first sliders 10, and the top of the support platform 1 is fixedly installed with two mutually symmetrical first guide rails 8, and the two first sliders 10 are respectively slidably installed in the two first guide rails 8, so as to realize the sliding installation of the clamp 9 on the support platform 1.

[0031] See also Figure 4 and Figure 5In the embodiment of the present invention, the slide seat 16 includes two symmetrically arranged clamping blocks 161, a threaded groove is arranged between the two clamping blocks 161, the screw rod 24 passes through the threaded groove, and the screw rod 24 is threadedly connected with the two clamping blocks 161 through the threaded groove, a second guide rail 17 is fixedly installed on the top of the connecting plate 15, two second sliders 18 are slidably installed in the second guide rail 17, the two clamping blocks 161 are fixedly connected with the two second sliders 18 respectively, the tops of the two clamping blocks 161 are fixedly installed with semi-circular disks 19, the tops of the two semi-circular disks 19 are fixedly installed with semi-cylinders 34, the top of one of the semi-cylinders 34 is fixedly installed with a connecting cap 20, the bottom end of the connecting cap 20 is fixedly connected with a spring 21, the bottom end of the spring 21 is fixedly connected with a locking ring 22, the locking ring 2 Ear plates 23 are fixedly installed on both sides of 2. When the locking ring 22 is sleeved on the two semi-circular disks 19, the two clamping blocks 161 fit together, thereby locking the two clamping blocks 161; when the rare earth metal plate is sheared, the clamp 9 needs to be reset. At this time, the locking ring 22 is pulled upward by the ear plate 23 to separate the locking ring 22 from the semi-circular disk 19, thereby releasing the lock of the two semi-circular disks 19, so that the two clamping blocks 161 can be separated, and then the clamp 9 can be pulled to move to reset the clamp 9. After the clamp 9 is reset, the ear plate 23 is released. At this time, under the elastic force of the spring 21, the locking ring 22 moves downward to be sleeved on the two semi-circular disks 19 again, and the semi-circular disks 19 can be locked again, so that the two clamping blocks 161 fit together again, and the two clamping blocks 161 can be threadedly connected with the screw 24 again.

[0032] Working principle: When in use, the rare earth metal plate is fixed in the fixture 9, and then the hydraulic cylinder 3 drives the hinge 4 to move downward. When the hinge 4 moves downward, it drives the rack 31 to move downward. When the rack 31 is engaged with the gear 30 and the rack 31 moves downward, the rack 31 drives the gear 30 to rotate. When the gear 30 rotates, it drives the connecting shaft 26 to rotate through the one-way bearing 29. When the connecting shaft 26 rotates, it drives the driven wheel 25 to rotate through the driving wheel 27 and the transmission belt 28, thereby driving the screw 24 to rotate, so that the slide 16 moves toward the direction close to the gantry 2. When the slide 16 moves, it drives the rare earth metal plate inside the fixture 9 to move through the connecting plate 15. When the shearing knife 6 is about to contact the rare earth metal plate, the rack 31 is separated from the gear 30, so that the slide 16 stops moving, thereby stopping the movement of the rare earth metal plate to avoid affecting the shearing of the rare earth metal plate. Then the shearing knife 6 starts to shear the rare earth metal plate. After the shearing is completed, the output end of the hydraulic cylinder 3 contracts, thereby driving the rack 31 to move upward through the hinge 4. When the rack 31 is meshed with the gear 30, the gear 30 rotates in the opposite direction. At this time, the rotation of the gear 30 only drives the outer ring of the one-way bearing 29 to rotate, and the inner ring of the one-way bearing 29 does not rotate, so that the connecting shaft 26 does not rotate, and then the clamp 9 does not move;

[0033] After the rare earth metal plate is sheared, the clamp 9 needs to be reset. At this time, the locking ring 22 is pulled upward through the ear plate 23 to separate the locking ring 22 from the semi-circular disk 19, thereby releasing the lock on the two semi-circular disks 19 and allowing the two clamping blocks 161 to be separated. Then the clamp 9 can be pulled to move and reset. After the clamp 9 is reset, the ear plate 23 is released. At this time, under the elastic force of the spring 21, the locking ring 22 moves downward and can be re-sleeved on the two semi-circular disks 19, so that the semi-circular disks 19 can be locked again, so that the two clamping blocks 161 can be re-fitted, and the two clamping blocks 161 can be re-threadedly connected to the screw 24.

[0034] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
