Abstract

The invention provides a universal internal rotation machine device for engineering wheels. The universal internal rotation machine device for engineering wheels comprises a frame, a sliding block, a spinning roller mechanism, a pressing mechanism and a rotating platform are arranged in the frame, and the upper end of the sliding block is connected with an axial feeding mechanism. The lower end of the sliding block is connected with the spinning roller mechanism, and a spinning roller is arranged at the bottom of the spinning roller mechanism. A mold is fixed on the rotating platform, and the rotating platform is connected with a transmission mechanism through a main shaft. The pressing mechanism is connected with a pressing cylinder, and a workpiece is fixed in the mold through the pressing mechanism. The spinning roller mechanism is further connected with a radial feeding mechanism, and the axial feeding mechanism and the radial feeding mechanism are matched with an automatic control numerical control system to achieve feeding machining according to a product curve. The invention further provides a method for machining wheels through the universal internal rotation machine device for engineering wheels. The method specifically comprises the steps of mold fixing, feeding, spinning roller internal spinning, returning and workpiece taking and the like, unequal-thickness extension machining on engineering wheels can be completed, and the universal internal rotation machine device can be widely applied to the field of machining of rims of engineering wheels.

Description

technical field [0001] The invention relates to the technical field of engineering wheel processing, in particular to a general internal rotation machine device for engineering wheels and a method for processing engineering wheels by using the internal rotation machine device. Background technique [0002] The engineering wheel is an important part of the engineering vehicle, and its core component is the inner wheel rim. The performance of the wheel rim directly determines whether the engineering vehicle is safe or not. The rim of the existing engineering vehicle is made of high-strength steel plate, which needs to be prepared through blanking, reeling, welding, rounding, spinning and machining. [0003] At present, the processing technology of engineering wheels is relatively mature. For example, the patent CN102555667A discloses a manufacturing process of an engineering vehicle integral rim and its rim body, including the rim body. The reel, the pressed material blank, t...
