[0032] Working principle: This utility model discloses a one-time forming device for punching and deburring forged gear blanks. During use, the gear to be processed is placed at the top of the inner cavity of the lower outer split edge punching die 10. The bottom of the gear to be processed is in contact with the top of the punching punch 14. Then, the hydraulic rod 4 is controlled to drive the fixed plate 5 and the upper punching die 6 to move downward. The fixed plate 5 moves downward and touches the swing rod 25. The swing rod 25 flips downward and compresses the spring 24. When the fixed plate 5 moves downward away from the swing rod 25, the swing rod 25 flips upward to its original position under the action of the spring 24. The upper punching die 6 moves downward to the inner cavity of the lower outer split edge punching die 10 and touches the gear to be processed. As the upper punching die 6 moves downward, the gear also continues to move downward. The lower outer split edge punching die 10 deburrs the gear, while the punching punch 14 punches the gear. The setting of the punching hole 9 facilitates the punching work of the punching punch 14.

[0033] After the punching and deflashing are completed, the hydraulic rod 4 is controlled to move the fixed plate 5 and the upper punch die 6 upward. The fixed plate 5 touches the swing rod 25 and moves upward. The swing rod 25 is restricted by the fixed block 23 and will not flip upward. Therefore, the swing rod 25 moves upward with the fixed plate 5. The swing rod 25 drives the horizontal plate 21 and the connecting plate 18 to move upward. The horizontal plate 21 drives the movable frame 22 to move upward on the outer edge of the support rod 3. The connecting plate 18 drives the movable seat 13 to move upward through the movable rod 17. The movable seat 13 moves upward and pushes out the processed gear, which makes it easy to remove the part.

[0034] After the gear is ejected away from the lower outer parting die 10, the hydraulic rod 4 stops working. Then, the wing screw 20 is unscrewed to release the fixing of the movable rod 17. The movable rod 17 is then moved away from the movable seat 13 and the slot 16. The movable seat 13 moves downward to its original position under the action of gravity. Then, the horizontal plate 21 is moved upward. The horizontal plate 21 drives the swing rod 25, the connecting plate 18 and the movable rod 17 to move upward. Then, the swing rod 25 is flipped downward, so that the swing rod 25 tends to be vertical. Then, the horizontal plate 21 is moved downward until the swing rod 25 moves downward below the bottom of the fixed plate 5. Then, the force applied to the swing rod 25 is released, and the swing rod 25 continues to remain horizontal under the elastic action of the spring 24. At this time, the swing rod 25 is located at the bottom of the fixed plate 5. Then, the horizontal plate 21 and the connecting plate 18 are moved downwards. The connecting plate 18 moves to the bottom and fits against the top of the base 1. At this time, the movable rod 17 corresponds to the slot 16 and the through hole 15. Then, the movable rod 17 is moved towards the through hole 15. The movable rod 17 moves to the through hole 15 until the vertical plate 19 fits against the side wall of the connecting plate 18. Then, the wing screw 20 is tightened to fix the movable rod 17. After that, the punching and deburring work continues.

[0035] The process of removing burrs, punching, and shaping forged gears is completed in one step, greatly improving the production efficiency of forged gears. At the same time, by resetting the lower outer parting die 10, the movable seat 13 can be moved upward in conjunction with the lower outer parting die 10. The upward movement of the movable seat 13 pushes out the processed gear, making it convenient to remove the part. In other words, this device can both reset the lower outer parting die 10 and push out the processed gear, achieving two goals at once. It has multiple functions and greatly facilitates the processing operation.
