Enveloping rolling forming method for thin-wall high-rib cylindrical component

Abstract

The invention relates to an enveloping rolling forming method for a thin-wall high-rib cylindrical component. The method comprises the steps that a circular ring blank is placed in a sleeve, the outerwall of the circular ring blank is tightly attached to the inner wall of the sleeve, the outer wall of an enveloping roller is tightly attached to the inner wall of the circular ring blank, and an upper annular cover plate and a lower annular cover plate are tightly attached to the upper end surface and the lower end surface of the sleeve to restrain the axial height of the circular ring blank; the sleeve drives the circular ring blank to rotate actively around the axis of the circular ring blank at a rotating speed, the enveloping roller is driven to rotate actively around the axis of the enveloping roller at a rotating speed and feed rolls the circular ring blank at a speed v in the radial direction; under the combined action of the enveloping roller and the sleeve, the enveloping roller and the circular ring blank are subjected to enveloping movement, and the circular ring blank is subjected to continuous local plastic deformation until a high rib is completely enveloped and formedby the enveloping roller; and the enveloping roller comprises a longitudinal rib cavity, a transverse rib cavity and a clamping end, and the longitudinal rib cavity and the transverse rib cavity arerespectively used for forming a longitudinal rib and a transverse rib of the target thin-wall high-rib cylindrical component. According to the enveloping rolling forming method for the thin-wall high-rib cylindrical component, the thin-wall high-rib cylindrical component is subjected to enveloping and rolling forming, the forming component is good in performance, the process production efficiencyand the material utilization rate are high.

Description

technical field [0001] The invention relates to the field of manufacturing thin-walled and high-rib cylindrical components, in particular to an envelope rolling forming method for thin-walled and high-rib cylindrical components. Background technique [0002] Thin-walled and high-reinforced cylindrical members have the advantages of high strength and light weight, and are widely used in industrial fields such as transportation, energy, aerospace, and national defense science and industry. Thin-walled and high-reinforced cylindrical components have thin walls, high ribs, and criss-crossed ribs in a grid pattern. The complex cross-sectional shape makes high-performance manufacturing of such components difficult. At present, the methods of manufacturing thin-walled and high-rib cylindrical members are mainly cutting and welding. Machining thin-walled and high-rib cylindrical components is to pre-prepare simple cylindrical blanks by rolling or forging, remove excess metal on the...
