Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment for polygonal slewing bearing ring parts, and particularly relates to a top circle tooling for polygonal slewing bearing ring parts. Background Technique

[0002] In the actual ring rolling production process, due to reasons such as equipment damage, aging or improper manual operation, the deformation of ring forgings into polygonal ring forgings often occurs during forging. In previous production, whenever such a situation occurred, the workshop usually adopted a cold straightening method to reshape the ring into a circle again. Cold straightening means directly placing the forged and cooled ring forging on the ring rolling machine for rolling, so as to reshape the ring into a circle again.

[0003] After retrieval, the patent publication number CN210907475U discloses a top circle device for polygonal ring forgings, including: a bracket, two spacing rods arranged side by side at the front of the bracket, a blocking column arranged at the rear of the bracket, and a hydraulic cylinder arranged in the middle of the bracket. A top rod that abuts against the blocking column is provided at the bottom end of the hydraulic cylinder body. The outer convex deformation section of the polygonal ring forging can be placed on the bracket between the two spacing rods and the hydraulic cylinder. After the piston rod of the hydraulic cylinder extends, the piston rod of the hydraulic cylinder can abut against the outer convex deformation section, so that the inner ends of both sides of the outer convex deformation section can respectively abut against the two spacing rods, so that the outer convex deformation section can be pushed into a circle by the hydraulic cylinder. It also includes: an outer cushion block. When the outer convex deformation section of the polygonal ring forging is placed on the bracket, the outer cushion block is used to lift the polygonal ring forging so that the polygonal ring forging can be placed horizontally. The above-mentioned top circle device for polygonal ring forgings can quickly top circle the ring forging, and has low energy consumption, and is suitable for the top circle of polygonal ring forgings of different sizes.

[0004] When the existing ring part top circle tooling is actually used, when performing top circle operations on different positions of the ring part, it is necessary to manually operate to change the position where the ring part needs to be topped. This operation method has a large labor intensity and low efficiency. Moreover, when the existing ring part top circle tooling performs top circle operations on the ring part, it is not easy to control the acting force exerted by the top circle block on the ring part. When the acting force exerted by the top circle block on the ring part is small, it is likely to result in a poor top circle effect. When the acting force exerted by the top circle block on the ring part is large, it is likely to cause the ring part to break and be damaged. For this reason, we propose a top circle tooling for polygonal slewing bearing ring parts to solve the existing problems. Content of the Utility Model

[0015] By means of the above technical solution, the present utility model provides a top circle tooling for a polygonal slewing bearing ring, which has at least the following beneficial effects:

[0016] 1. Through the cooperation of a series of structures in the present utility model, when the staff performs the top circle operation on the polygonal slewing bearing ring, after the staff places the polygonal slewing bearing ring at the center position of the top of the workbench, the staff starts the first electric push rod and the second electric push rod in the two side directions of the present utility model. The telescopic movement of the first electric push rod will drive the first top circle block to move. When the first top circle block contacts the outer wall of the polygonal slewing bearing ring, the second pressure monitoring sensor will detect the acting force between the first top circle block and the polygonal slewing bearing ring in real time. The telescopic movement of the second electric push rod will drive the second top circle block to move. When the outer wall of the second top circle block contacts the inner wall of the polygonal slewing bearing ring, the first pressure monitoring sensor will detect the acting force between the second top circle block and the polygonal slewing bearing ring in real time. The first top circle block and the second top circle block can simultaneously perform the top circle operation on the outer side wall and the inner side wall of the polygonal slewing bearing ring, improving the quality of the shaping of the polygonal slewing bearing ring. The staff can observe the acting force caused by the first top circle block and the second top circle block on the polygonal slewing bearing ring through the display screen, so as to facilitate the staff to control the acting force caused by the first top circle block and the second top circle block on the polygonal slewing bearing ring, avoiding the situation that the acting force caused by the first top circle block and the second top circle block on the polygonal slewing bearing ring is too small and resulting in poor top circle effect, and avoiding the situation that the acting force caused by the first top circle block and the second top circle block on the polygonal slewing bearing ring is too large and resulting in the fracture and damage of the ring, thereby further improving the quality of the shaping of the polygonal slewing bearing ring.

[0017] 2. Through the cooperative setting of structures such as a stepper motor, a driving gear, a driven gear, a rotating plate, and a rotating shaft, when the crown circle operation at a certain position on the polygonal slewing bearing ring is completed, the operator starts the stepper motor. The start of the stepper motor will indirectly drive the rotating plate to rotate a certain position. The rotation of the rotating plate by a certain position will indirectly drive the first crown circle block and the second crown circle block to rotate to a certain position, and then repeat the above crown circle operation. Therefore, when the present utility model performs crown circle operations on different positions of the polygonal slewing bearing ring, there is no need for manual operation to replace the position of the crown circle required for the polygonal slewing bearing ring, reducing the labor intensity and improving the efficiency of the crown circle of the polygonal slewing bearing ring.

[0018] 3. Through the cooperative setting of structures such as the first crown circle block, the second crown circle block, the second connecting plate, the seventh connecting plate, the third connecting plate, and the fourth connecting plate, when the operator needs to perform crown circle operations on polygonal slewing bearing rings of different sizes, the operator can replace the first crown circle block and the second crown circle block to achieve crown circle operations on polygonal slewing bearing rings of different sizes, enhancing the versatility.
