Technical Field

[0001] The utility model relates to the technical field of forging turnover, in particular to a turnover forging device. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and sizes. Its advantage is that it can improve the properties of the metal and make its shape and size more adaptable. In the forging process, flipping is an important part of the forging operation.

The slider 4 is slidably installed in the slide 3, and the clamping frame 5 is rotatably installed between the two sliders 4; the height of the slide 3 is lower than the height of the forging head 2, and a support platform 6 is installed on the support frame 1 by bolts. The support platform 6 is located below the clamping frame 5, and a driving mechanism is provided on the side wall of the support frame 1. By setting the flip mechanism, the blank is placed on the support platform 6, and the hydraulic rod provided on the support frame 1 is activated. , clamp the billet, and hammer the billet by driving the forging head 2 through the hydraulic cylinder. This is the existing technology and will not be described in detail here. When the billet needs to be turned over, the slider 4 is moved upward to make the slider 4 move vertically inside the chute 3. When the slider 4 drives the clamping frame 5 and the billet to rise to a preset height, the clamping frame 5 is turned over, so that the billet is turned over. After completion, the slider 4 is moved downward to drive the clamping frame 5 and the billet back to their original positions to continue forging, so that the billet does not need to be taken out of the clamping frame 5. Compared with the existing technology, it can be directly turned over in the clamping state, saving processing steps and speeding up processing efficiency.

[0033] Reference Figure 1-5 The driving mechanism includes a gear 7 and a meshing tooth 8. The gear 7 is rotatably mounted on the right side of one of the sliders 4, and the meshing tooth 8 is fixedly mounted on the side wall of the support frame 1. By setting the driving mechanism, since the gear 7 is mounted on the slider 4, when the slider 4 moves to the preset position, the gear 7 and the meshing tooth 8 come into contact. At this time, the gear 7 and the meshing tooth 8 are meshed. By continuing to move the slider 4 upward, the gear 7 rotates, thereby driving the clamping frame 5 to rotate through the spline shaft 11 and the spline sleeve 10, providing a driving force for the flipping of the clamping frame 5;

[0034] Reference Figure 1-5 , a screw rod 9 is rotatably installed inside one of the chutes 3, the screw rod 9 is sleeved inside the slider 4, and the screw rod 9 and the slider 4 are threadedly connected. A motor 17 is fixedly installed on the top of the support frame 1, and the output end of the motor 17 is fixedly connected to the top of the screw rod 9. By setting the screw rod 9 and starting the motor 17, the screw rod 9 is driven to rotate, and through the cooperation of the chute 3, one of the sliders 4 is moved upward, and through the connection of the clamping frame 5, the two sliders 4 are moved upward together;

[0035] Reference Figure 1-5, a spline sleeve 10 is rotatably installed inside one of the sliders 4, and the side of the spline sleeve 10 close to the clamping frame 5 is fixedly connected to the clamping frame 5. The right side of the spline sleeve 10 is set as an opening. A spline shaft 11 is slidably installed inside the spline sleeve 10, and the right side of the spline shaft 11 is fixedly connected to the gear 7. A limit groove 12 is provided on the surface of the spline shaft 11, and a limit ring 13 is rotatably sleeved on the surface of the limit groove 12. Guide grooves 14 are provided on the front and rear sides of the slider 4. A guide rod 15 is slidably installed inside the guide groove 14, and the two guide rods 15 are opposite to each other. One side is fixedly connected to the limit ring 13. By setting the spline sleeve 10, when the slider 4 moves upward, the gear 7 rotates to drive the spline shaft 11 to rotate. Through the cooperation of the spline shaft 11, the spline sleeve 10 drives the clamping frame 5 to rotate. When the slider 4 moves downward, the guide rod 15 is moved to the right, driving the limit ring 13 to move to the right. Through the connection between the limit ring 13 and the spline shaft 11, the spline shaft 11 moves to the right, driving the gear 7 and the meshing teeth 8 to be dislocated, so that after the clamping frame 5 is flipped, it will not flip again during the return process;

[0036] Reference Figure 1-5 The side wall of the support frame 1 is provided with a changing groove 16, and the guide rod 15 is slidably sleeved inside the changing groove 16. By setting the changing groove 16, when the slider 4 moves upward, the guide rod 15 moves inside the changing groove 16. Since the initial section of the changing groove 16 is linear and then inclined, it is ensured that after the gear 7 rotates, the guide rod 15 drives the gear 7 and the meshing teeth 8 to be staggered through the cooperation of the changing groove 16. The descending section of the changing groove 16 is initially linear and then inclined, so that the guide rod 15 gradually returns to its initial position in the changing groove 16 during the descending process. The overall shape of the changing groove 16 is similar to a U-shaped with both the top and bottom inclined upward.

[0037] Specifically, the working process or working principle of the flip forging device is as follows: when in use, the blank is placed on the support table 6, the blank is clamped by starting the hydraulic rod set on the support frame 1, and the forging head 2 is driven by the hydraulic cylinder to hammer the blank. When the blank needs to be flipped, the motor 17 is started to drive the screw rod 9 to rotate, and through the cooperation of the slide groove 3, one of the sliders 4 is moved upward, and through the connection of the clamping frame 5, the two sliders 4 are moved upward together. When the slider 4 moves to the preset position, the gear 7 and the meshing tooth 8 are in contact. At this time, the gear 7 and the meshing tooth 8 are meshed, and by continuing to move the slider 4 upward, the gear 7 rotates, the rotation of gear 7 drives the spline shaft 11 to rotate, and through the cooperation of spline shaft 11, the spline sleeve 10 drives the clamping frame 5 to rotate. When the slider 4 moves upward, the guide rod 15 moves inside the redirecting groove 16. Since the initial section of the redirecting groove 16 is linear and then inclined, the guide rod 15 drives the gear 7 and the meshing teeth 8 to be staggered, so that after the clamping frame 5 flips over, it will not flip over again during the return process. The motor 17 is started in the reverse direction to drive the slider 4 to move downward. The descending section of the redirecting groove 16 is initially linear and then inclined, so that the guide rod 15 gradually returns to its initial position in the redirecting groove 16 during the descending process.
