Abstract

The invention relates to a special numerical-control spinning forming machine for hub parts of an engineering vehicle. The special numerical-control spinning forming machine comprises a lathe bed (1), a main shaft component (2), two spinning roller components (3) and a tail jacking component (4), wherein the lathe bed (1) is of a cross shape structure, the main shaft component (2) and the tail jacking component (4) are longitudinally mounted on the lathe bed (1), and the two spinning roller components (3) are transversely and symmetrically mounted on the lathe bed (1); the main shaft component (2) carries out rotary input by utilizing a main shaft motor, the spinning roller components (3) are of double-sliding-block symmetrical structures, each spinning roller head (314) is provided with four fixed mounting angles and can be regulated and mounted according to a process, and the tail jacking component (4) is in rigid connection with a main shaft tank so as to realize longitudinal synchronous feed. The special numerical-control spinning forming machine has the advantages that the strong spinning and flaring-flanging forming of cylinder-shaped and cone-shaped revolved body type parts can be realized, the spinning forming of annular thin-wall wheel hub parts with abnormal-shape curved buses can be realized, the energy and the materials are saved, and the automation degree and the working efficiency are high.

Description

technical field [0001] The invention relates to special numerical control forming equipment for engineering vehicle parts, in particular to a special numerical control spinning forming machine for engineering vehicle wheel hub parts. Background technique [0002] Spinning is a metal processing method used to form thin-walled hollow rotating parts. It is an advanced technology that can reduce or eliminate cutting. Nowadays, in the processing of cylindrical thin-walled parts with flanges in the wheel hub parts of engineering vehicles, the flanges are processed by hot turning, and the cylindrical parts are processed by turning, which consumes more energy in hot turning. In turning, the material utilization low rate. [0003] Chinese patent 201020644065.7 discloses a "multifunctional circular workpiece spinning forming machine", which is composed of a main drive device, a main drive shaft, a main forming wheel, two auxiliary forming wheels and a plurality of auxiliary rollers, ...
