A short die spinning forming device

Abstract

The invention relates to a short mould spinning forming device. The equipment comprises a core shaft, a part supporting ring, a forming ring, a forming ring driving module and a spinning roller. The core shaft is of a barrel-type structure, and one end of the core shaft is coaxially connected with a main shaft; the outer end surface of the core shaft connected with the main shaft is sleeved with the part supporting ring, and the part supporting ring is used for supporting parts to be machined; the forming ring is axially and movably arranged on the outer surface of a middle segment of the coreshaft in the circumferential direction; the forming ring driving module is mounted in a barrel cavity of the core shaft and used for driving the forming ring to move axially; and the spinning rolleris arranged on the periphery of the core shaft, and performs synchronous movement with the forming ring at a forming machining part of the parts. By arranging the independent part supporting ring andthe forming ring, through the matching reaction of the forming ring driving module and the core shaft, the machining efficiency of the parts is improved, reasonable material selection and replacementmaintenance can be carried out according to different using requirements, the universality is high, the machining quality is guaranteed while the whole weight is reduced, and the production cost is saved.

Description

technical field [0001] The invention relates to the field of metal forming equipment, in particular to a short die spinning forming device suitable for thin-walled cylindrical parts. Background technique [0002] Thin-walled cylindrical parts are widely used in industrial production, especially in aerospace and other fields, such as DF-XX, DF-XXX engine casings, launch vehicles, straight sections of missile casings, and large aero-engine casing parts. Spinning forming technology is recognized as one of the most effective process methods for manufacturing thin-walled cylindrical parts. It combines various process characteristics such as forging, drawing, extrusion, rolling and rolling, and has been widely used in the aerospace field. widely used. [0003] The spinning of cylindrical parts usually adopts the flow spinning method. During the spinning process, the rotary wheel pressurizes the metal thick-walled cylindrical blank that rotates with the mold, so that it produces ...
