Ring rolling forming device for integral ring rolling and bending of special-shaped joints

Abstract

The invention relates to a ring-rolling forming device for single-piece integral ring-rolling and bending of special-shaped joints, belonging to the technical field of forging in mechanical manufacturing. It includes a main roll mold, a core roll mold and a core roll mold briquetting block. The core roll mold and the core roll mold briquetting block are arranged in parallel, and are assembled with a ring rolling mandrel roll to form a cavity. The invention has simple structure, high production efficiency, the whole forging can be bent according to the shape, the metal streamline of the forging is continuous, and the product quality is good; the invention avoids the problem of large deformation processing stress, and its processing cost is low, which is convenient for popularization and use.

Description

technical field [0001] The invention relates to a ring-rolling forming device for single-piece integral ring-rolling and bending of special-shaped joints, belonging to the technical field of forging in mechanical manufacturing. Background technique [0002] The joint is a connecting part with a large cross-section change, a large round hole in the middle, and a special-shaped structure with a gradually changing thickness on the flange surface. In the process of its use, it generally needs to be forged to meet the requirements of use. However, due to the complex shape and thin thickness of the part, it is difficult to forge and form. The current manufacturing method is generally: forging the product as a whole. The whole ring is then machined to the final required size. The forming device used in this method makes the product have a large machining allowance during the processing, resulting in large processing stress, discontinuous product flow, and difficult final dimensiona...

Problems solved by technology

In the process of its use, it generally needs to be forged to meet the requirements of use. However, due to the complex shape and thin thickness of the part, it is difficult to forge and form. The current manufacturing method is generally: forging the product as a whole. The whole ring is then machined to the final required size. The forming device used in this method makes the product have a large machining allowance during the processing, resulting in large processing stress, discontinuous product flow, and difficult final dimensional accuracy. Guaranteed, but the manufacturing cost is high and the production efficiency is low
