Description

Technical Field

[0001] The utility model relates to the technical field of forging hole expansion, in particular to a ring rolling machine with an adjustable structure. Background Art

[0002] Ring rolling machine is a kind of rotary forging equipment with a long history. According to the structural characteristics of ring rolling equipment, it can be divided into two categories: vertical ring rolling machine and horizontal ring rolling machine. The former is suitable for medium and small rings, and the latter is suitable for the manufacture of large and extra-large rings. The vertical ring rolling machine is a main rolling wheel driven by an electric motor to rotate. In the process of downward pressure, it forms a pair of rollers with the core roller driven by the passive belt. The ring blank on the core roller is repeatedly rolled, and the inner and outer diameters of the ring are expanded, and the wall thickness is reduced, and the ring is gradually formed.

[0003] Publication No. CN208083302U discloses a ring rolling machine, which solves the problem of high maintenance cost and inconvenient operation of the ring rolling machine after the lever is worn by the auxiliary rolling roller shaft, and achieves the problem of easy maintenance and low maintenance cost of the ring rolling machine. However, during the use of the equipment, the range of hole expansion is fixed. When rolling and forming is required according to the hole diameter of the unforged part, it is necessary to disassemble and replace the core roller of the corresponding diameter, or directly place it on the core roller for processing, which is time-consuming and labor-intensive. If the core roller is not replaced, the ring forging is prone to deformation. For this reason, we propose a ring rolling machine with an adjustable structure. Utility Model Content
