[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, by setting a finishing component, through the mechanical cooperation of the transmission gear, the rotating disk, the connecting shaft, the toggle rod, the baffle plate and the tension spring, the transmission gear can drive the connecting shaft to rotate in one direction, that is, when the moving rack moves downward, the connecting shaft does not rotate, and when the moving rack moves upward, the connecting shaft rotates, so that the component only runs in the process of the forging block rising, ensuring the stability of the inner ring blank during the forging of the forging block, improving the processing quality of the inner ring blank, and when the forging block moves upward, the forging block drives the transmission gear to rotate through the connecting plate and the moving rack. At this time, the transmission gear drives the connecting shaft to rotate through the transmission, and the connecting shaft passes through the third bevel gear, the fourth bevel gear, the rotating rod, the first bevel gear, the second bevel gear and the second rotating rod. The shaft drives the rotating gear plate to rotate, and the rotating gear plate drives the supporting wheel to rotate through the linkage gear, the moving rod, the rotating tube, the sixth bevel gear and the fifth bevel gear, and the supporting wheel drives the inner ring blank to rotate relatively around its own axis. At the same time, the connecting shaft drives the cam to rotate through the driving wheel, the transmission belt and the driven wheel, and the cam cooperates with the reset spring to drive the sliding plate to reciprocate, and the sliding plate drives the trimming hammer through the sliding rod to hammer and trim the periphery of the inner ring blank. On the one hand, the outer periphery of the inner ring blank can be knocked and trimmed to improve the flatness of the outer periphery of the inner ring blank. On the other hand, with the circular motion of the inner ring blank itself, the outer periphery of the inner ring is evenly stressed, which can make the periphery of the inner ring closer to a perfect ring, reduce the roundness difference of the inner ring, and improve the quality of the finished product.

[0028] 2. In the present invention, a support and protection component is provided, and a worker rotates a knob, and the knob drives the adjusting toothed disc to rotate through the rotating shaft, and the adjusting toothed disc drives the moving screw to rotate through the adjusting gear, and the moving screw drives the supporting wheel to move through the screw seat, and the supporting wheel supports and limits the inner circumference of the inner ring blank, and by controlling the moving stroke of the screw seat, the inner ring blanks of different specifications can be limited and stabilized, and the movement of the inner ring blank during processing can be avoided to affect the forging effect, and at the same time, because one of the supporting wheels is always arranged directly opposite to the dressing hammer, when the dressing hammer strikes the inner ring blank forging, the supporting wheel can always provide outward support of sufficient strength to the inner ring blank, and the inner ring blank can be prevented from being deformed or damaged due to uneven internal and external forces, thereby improving the protectiveness of the device to the inner ring processing and forging.

[0029] 3. In the present invention, by providing an impurity collection component, during the forging process, impurities will be generated as the forging block and the trimming hammer strike the inner ring rough blank. The bellows conveys the adsorption force to the collection groove through the adsorption groove, the collection box and the connecting pipe, so that the impurities in the collection groove enter the collection box through the communication groove and the connecting pipe, realizing the collection of impurities and the self-cleaning of impurities, thereby ensuring the relative cleanliness of the workbench surface and providing a relatively good processing environment.

Both ends of the return spring 815 are fixedly connected to one side of the sliding plate 814 and one side of the mounting block 820 respectively. A mounting plate 804 is fixedly connected in the cavity 9. The rotating rod 812 is rotatably connected to the mounting plate 804, and the bottom of the second rotating shaft is rotatably connected to the inner bottom wall of the cavity 9 through a bearing. Two transmission gears 813 are rotatably connected to the outer surface of the connecting shaft 810. A moving rack 802 is engaged with one side of each transmission gear 813. A through groove is formed on the top of the workbench 1, and the through groove is communicated with the cavity 9. The moving rack 802 is slidably connected in the through groove, and one end of each of the two moving racks 802 extends outside the cavity 9 and is fixedly connected to the same connecting plate 801. One side of the connecting plate 801 is fixedly connected to one side of the forging block 4. A sliding hole is formed at the bottom of the moving rack 802, and a fixed sliding rod 803 is slidably connected in the sliding hole. The other end of the fixed sliding rod 803 is fixedly connected to the inner bottom wall of the cavity 9. A ratchet tooth groove 828 is formed inside the transmission gear 813. A rotating disc 829 is rotatably connected in the ratchet tooth groove 828. The rotating disc 829 is fixedly connected to the connecting shaft 810.

A transmission belt 807 is connected between the driving wheel 809 and the driven wheel 817. A through groove is formed at the top of the workbench 1. The transmission belt 807 extends to the outside of the cavity 9 through the through groove.

[0043] The specific implementation method is as follows: By setting the trimming assembly 8, through the mechanical cooperation of the transmission gear 813, the rotating disk 829, the connecting shaft 810, the shifting rod 830, the baffle 832 and the tension spring 831, the one-way rotation of the connecting shaft 810 driven by the transmission gear 813 can be realized. That is, when the moving rack 802 moves downward, the connecting shaft 810 does not rotate. When the moving rack 802 moves upward, the connecting shaft 810 rotates, so that the assembly only operates during the upward movement of the forging block 4, ensuring the stability of the inner ring blank during the forging of the forging block 4 and improving the processing quality of the inner ring blank. And when the forging block 4 moves upward, the forging block 4 drives the transmission gear 813 to rotate through the connecting plate 801 and the moving rack 802. At this time, the transmission gear 813 drives the connecting shaft 810 to rotate through the transmission belt 807. The connecting shaft 810 drives the rotating tooth disk 827 to rotate through the third bevel gear 808, the fourth bevel gear 811, the rotating rod 812, the first bevel gear 805, the second bevel gear 806 and the second rotating shaft. The rotating tooth disk 827 drives the supporting wheel 702 to rotate through the linkage gear 826, the moving rod 825, the rotating tube 823, the sixth bevel gear 822 and the fifth bevel gear 821. The supporting wheel 702 drives the inner ring blank to rotate relative to its own axis. At the same time, the connecting shaft 810 drives the cam 816 to rotate through the driving wheel 809, the transmission belt 807 and the driven wheel 817. The cam 816 cooperates with the return spring 815 to drive the sliding plate 814 to reciprocate. The sliding plate 814 drives the trimming hammer 818 through the sliding rod 819 to hammer and trim the periphery of the inner ring blank, and can perform knocking and trimming on the outer peripheral side of the inner ring blank to improve the flatness of the outer peripheral side of the inner ring blank.

[0044] The support and protection component 7 includes an adjustment gear disc 708. A rotating shaft is fixedly connected to the top of the adjustment gear disc 708. The rotating shaft is rotationally connected to the top of the fixed box 701. One end of the rotating shaft extends to the outside of the fixed box 701 and is fixedly connected to a knob 706. Adjustment gears 709 are rotationally connected to the periphery of the bottom of the adjustment gear disc 708. A moving lead screw 704 is fixedly connected to one side of the adjustment gear 709. One end of the moving lead screw 704 extends to the outside of the fixed box 701 and is rotationally connected to the fixed box 701. A lead screw seat 703 is threadedly connected to the outer surface of the moving lead screw 704. Two connecting seats are fixedly connected to the side of the lead screw seat 703 away from the moving lead screw 704. The support wheel 702 is rotationally connected between the two connecting seats through a third rotating shaft. A plurality of card slots 707 are formed in the top of the fixed box 701. Blocks 705 are fixedly connected to both sides of the bottom of the knob 706. The blocks 705 are engaged with the card slots 707. The blocks 705 are flexible plastic blocks. An installation part 824 is fixedly connected to the bottom of the lead screw seat 703. The installation part 824 is rotationally connected to the rotating pipe 823. The inner walls of the rotating pipe 823 and the moving rod 825 are both regular hexagons in cross-section.

[0045] The specific implementation method is as follows: By setting the support and protection component 7, the staff rotates the knob 706. The knob 706 drives the adjustment gear disc 708 to rotate through the rotating shaft. The adjustment gear disc 708 drives the moving lead screw 704 to rotate through the adjustment gear 709. The moving lead screw 704 drives the support wheel 702 to move through the lead screw seat 703. The support wheel 702 supports and limits the inner peripheral side of the inner ring blank. By controlling the moving stroke of the lead screw seat 703, inner ring blanks of different specifications can be limited and stabilized, avoiding the movement of the inner ring blank during the processing and affecting the forging effect. At the same time, since one of the support wheels 702 is always facing the trimming hammer 818, when the trimming hammer 818 hammers the inner ring blank, the support wheel 702 can always provide sufficient outward support for the inner ring blank, avoiding deformation or damage of the inner ring blank due to uneven internal and external forces.

[0046] The impurity collection component 5 includes a collection box 504. The collection box 504 is fixedly connected to one side of the workbench 1. A collection groove 503 is formed in the top of the workbench 1. A communication groove 501 is formed in one side of the workbench 1. A connecting pipe 502 is fixedly connected to the top of the collection box 504. The connecting pipe 502 is communicated with the communication groove 501. A wind box 505 is fixedly connected to the bottom of the collection box 504. An adsorption groove is communicated between the collection box 504 and the wind box 505, and a filter screen is arranged in the adsorption groove. The cross-section of the collection groove 503 is annular, and the collection groove 503 and the axis of the fixed box 701 are in the same position. Heating devices 6 are fixedly connected to both sides of the top of the workbench 1. The heating devices 6 are located on both sides of the collection groove 503.

[0047] The specific implementation method is as follows: By setting up the impurity collection component 5, during the forging process, impurities will be generated as the forging block 4 and the trimming hammer 818 strike the inner ring rough blank. The bellows 505 conveys the adsorption force to the collection groove 503 through the adsorption groove, the collection box 504, and the connecting pipe 502, so that the impurities in the collection groove 503 enter the collection box 504 through the communication groove 501 and the connecting pipe 502, realizing the collection of impurities.

[0048] Working principle: During use, the staff places the heated inner ring rough blank on the workbench 1. The staff rotates the knob 706, the knob 706 drives the rotating shaft to rotate, the rotating shaft drives the adjustment gear disk 708 to rotate, the adjustment gear disk 708 drives the adjustment gear 709 to rotate, the adjustment gear 709 drives the moving lead screw 704 to rotate, the moving lead screw 704 drives the lead screw seat 703 to move, and the lead screw seat 703 drives the support wheel 702 to move, and the support wheel 702 supports and limits the inner peripheral side of the inner ring rough blank.

[0049] After the inner ring blank is limited and supported, the staff starts the hydraulic device 3. The hydraulic device 3 drives the forging block 4 to reciprocate up and down and forges the inner ring blank. When the forging block 4 descends, the forging block 4 drives the connecting plate 801 to move downward, the connecting plate 801 drives the moving rack 802 to move downward, and the moving rack 802 drives the transmission gear 813 to rotate. During this process, the ratchet groove 828 of the transmission gear 813 rotates clockwise, the ratchet groove 828 drives the toggle lever 830 to deflect around the pin shaft, and the tension spring 831 drives the toggle lever 830 to reset. At this time, the transmission gear 813 cannot drive the connecting shaft 810 to rotate through the transmission belt 807. When the forging block 4 resets upward, the forging block 4 drives the connecting plate 801 to move upward, the connecting plate 801 drives the moving rack 802 to move upward, and the moving rack 802 drives the transmission gear 813 to rotate. At this time, the transmission gear 813 drives the ratchet groove 828 to rotate counterclockwise, the ratchet groove 828 drives the toggle lever 830 to rotate.
