[0056] Working principle: After the staff connects the device to the power supply, they pull the sealing door 34, then place the workpiece on the upper surface of the load-bearing plate 15 and start the electromagnet 17 (the staff can control the specific start time of the electromagnet 17 according to the specific size of the workpiece. When the electromagnet 17 is not started, the electromagnet 17 is not magnetically adsorbed on one end of the matching shaft 13, so that when the load-bearing plate 15 rises, the matching toothed plates 16 on the left and right sides mesh with the matching gear 14 for transmission, and when the matching shaft 13 is driven to rotate, it only rotates on the surface of the electromagnet 17. When the electromagnet 17 is started, the electromagnet 17 is electrically The magnet 17 is attracted to one end of the mating shaft 13 due to its magnetism. When the mating shaft 13 rotates, it can drive the electromagnet 17 to rotate, so that the workpiece can be clamped through subsequent linkage). Then, the lifting cylinder 4 is started to drive the load-bearing plate 15 to move upward. When the load-bearing plate 15 moves upward, the mating toothed plates 16 on the left and right sides are meshed with the mating gear 14 for transmission. When the mating shaft 13 is driven to rotate, the electromagnet 17 and the mating shaft 13 are fixedly connected due to magnetic attraction, thereby driving the second pulley 18 to rotate. The second pulley 18 is driven by the belt. The transmission drives the first pulley 9 to rotate, and the first pulley 9 drives the rotating shaft to rotate and drives the linkage gear 10 to rotate, so that the linkage gear 10 drives the linkage plate 7 to slide and move relatively in the sliding groove 5 through the sliding block 6 through the linkage tooth 11, so that the buffer pad 33 on the surface of the connecting box 12 fits with the surfaces on both sides of the workpiece, so that the connecting box 12 clamps both sides of the workpiece, and then the staff starts the first driving motor 30, and the first driving motor 30 drives the driving rod 26 to rotate, and the driving rod 26 is connected to the second screw sleeve 27 through the positive and negative thread grooves on the surface. The second screw sleeve 27 moves so that the second screw sleeve 27 moves relatively and drives the clamping plate 28 to clamp the other front and rear surfaces of the workpiece, thereby clamping and fixing it. When the position of the workpiece needs to be adjusted, the second drive motor 32 is started, so that the second drive motor 32 drives the threaded rod 22 to rotate. When the threaded rod 22 rotates, it drives the first screw sleeve 23 to move. Through the engagement of the first screw sleeve 23 with the threaded rod 22, the first screw sleeve 23 drives the support seat 24 to drive the clamping box 25 to move forward and backward, so that the clamping plate 28 drives the workpiece to move forward and backward, which is used to move the position of the workpiece.

[0057] In summary, the clamping device for the forging machine can place the workpiece on the surface of the bearing plate 15 through the provided rising cylinder 4, and the workpiece is fed through the rising cylinder 4. At the same time, during the rising process, the matching gear 14 is driven to rotate through the matching toothed plates 16 on both sides of the bearing plate 15, and the second pulley 18 is driven to rotate, so that when the second pulley 18 drives the first pulley 9 to rotate through the belt, the first pulley 9 drives the matching gear 14 to rotate through the rotating shaft, so that the matching gear 14 is engaged with the linkage tooth 11 when rotating, so that the linkage plate 7 drives the connecting box 12 to clamp the surfaces on both sides of the workpiece, thereby realizing automatic positioning and clamping of the workpiece during feeding, and can clamp workpieces of different sizes at the same time. The automation of the device is realized and manpower is saved at the same time. When the driving rod 26 is driven to rotate by the first driving motor 30, the second screw sleeve 27 can be driven to move relatively through the forward and reverse threaded grooves to drive the clamping plate 28 to clamp the front and rear sides of the workpiece. The four side surfaces of the workpiece can be clamped and limited by cooperation with the connecting box 12. At the same time, the second driving motor 32, the threaded rod 22, the first screw sleeve 23, and the support seat 24 cooperate with each other, so that the second driving motor 32 can drive the clamping box 25 to move forward and backward, so that after clamping the workpiece, the clamping plate 28 drives it to move forward and backward to adjust the position of the workpiece. There is no need for staff to remove the workpiece for re-clamping and forging, thereby improving the forging efficiency.
