Description

Technical Field

[0001] The present application relates to the technical field of ring rolling machines, and in particular to a flange ring rolling machine. Background Art

[0002] Ring rolling machine is a device used to produce various seamless ring forgings such as flanges. By placing the ring forging to be processed on the core roller of the ring rolling machine, the wall thickness of the ring forging is reduced, the diameter is enlarged, and the cross-sectional profile is formed under the rotation of the main roller and the linear motion of the cone roller. The main roller will have defects such as wear after long-term use, resulting in insufficient dimensional accuracy of the rolled product.

[0003] At present, the main roller on the conventional ring rolling machine is integrally formed. When some special-shaped ring forgings such as flanges need to be processed or the main roller is worn, the main roller needs to be removed and reinstalled with a new one, which has a high cost.

[0039] The working principle of the embodiment of the present application is as follows: when the roller sleeve 43 needs to be replaced, the hydraulic cylinder 31 is started to sleeve the guide ring 34 on one end of the mandrel 33, and the hydraulic cylinder 32 is started to drive the mandrel 33 to move toward the axial ring rolling mechanism 2. When the mandrel 33 is away from the main roller 42, the guide ring 34 is separated from the mandrel 33 by the hydraulic cylinder 31, and the lifting hydraulic cylinder 61 is started to make the support plate 51 contact with the bottom of the main roller 42 to support the main roller 42. At this time, the worker uses a tool to align the flange 44 and the upper roller sleeve cover 45 with the main roller. 42 is separated, thereby separating the main roller 42 from the drive shaft 411, starting the drive motor 71, and driving the support block 52 to move away from the bracket 41, so that the axis of the main roller 42 and the axis of the drive shaft 411 are misaligned. The worker removes the roller sleeve 43 from the main roller 42 and replaces it with a new roller sleeve 43. Then, the moving mechanism 7 is driven to make the support block 52 drive the main roller 42 to reset. The worker re-installs the main roller 42 on the drive shaft 411, lifts the hydraulic cylinder 61 to drive the support plate 51 to reset, and completes the replacement of the roller sleeve 43.
