Problems solved by technology
Since the two single metal rings are rolled and formed separately, this method has many procedures, time-consuming and laborious, and low production efficiency
And when the two single-metal rings formed by rolling are combined and assembled, only elastic deformation or small plastic deformation occurs at the contact interface of the rings, which leads to poor interface contact quality and low connection strength of the bimetal rings manufactured by this method, which cannot meet the requirements of Requirements for service performance and service life of high-performance bimetallic rings

The invention relates to a precise roll forming method for bimetallic rings. The method comprises: S1, obtaining an outer ring blank and an inner ring blank; S2, assembling the outer ring blank and the inner ring blank; S3, placing a core roller in the inner ring blank; S4, placing a drive roller outside the outer ring blank; S5, driving the drive roller to rotate through a drive device and driving the core roller to perform linear feed movement radially, wherein the outer ring blank and the inner ring blank are attached closely constantly to produce continuous local plastic deformation with the wall thickness reducing and the diameter expanding; and S6, stopping feed of the core roller and getting the core roller back when the outer diameter of the outer ring blank reaches a preset value of the outer diameter of a bimetallic ring. According to the precise roll forming method, the bimetallic ring is formed integrally through one step through continuous local plastic deformation, so that the method has the advantage that energy and materials are saved, the production cost is reduced, and the yield is improved. The bimetallic ring interface contact quality is good, the connection strength is high, and requirements of service performances and service lives of high-performance bimetallic rings can be met.
Description
technical field [0001] The present invention relates to a rolling forming method of a ring, in particular to a precision rolling forming method of a bimetallic ring. Background technique [0002] The bimetallic ring is a composite ring composed of two different metals. The rings are tightly combined through various deformation and connection techniques, and the inner and outer rings will not be separated under the action of external forces. Compared with single metal rings, bimetallic rings can give full play to the best properties of the two metals, not only have excellent physical, chemical, mechanical and other comprehensive properties, but also save a lot of precious metals and reduce production costs. Metal rings are widely used in machinery, automobiles, trains, ships, metallurgy, chemicals, energy, aerospace and other industrial fields. [0003] At present, the main manufacturing method of bimetallic rings is to roll and form two single metal rings respectively throu...
