Complex-shape large thin-wall part and manufacturing process thereof

Abstract

The invention discloses a complex-shape large thin-wall part and a manufacturing process thereof, and relates to the technical field of complex-shape large thin-wall part production and machining. Thecomplex-shape large thin-wall part comprises a thin-wall part body, wherein one end of the thin-wall part body is provided with a head part, the other end of the thin-walled part body is provided with a tail part, and the thin-wall part body is internally provided with a cavity. The complex-shape large thin-wall part is obtained through adopting an integrated spinning forming process, so that themanufacturing time is greatly shortened; the head part is fixed in the spinning process, and a spinning machine acts on the outer surface of a hollow pipe all the time so that the length of the hollow pipe cannot be increased, and a finally obtained product is high in size precision; and the spinning forming process are few in step, so that the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the technical field of production and processing of large thin-walled parts with complex shapes, in particular to a large thin-walled part with complex shapes and a manufacturing process thereof. Background technique [0002] At present, large thin-walled parts with complex shapes require high precision, and it is extremely difficult to forge them. Generally, solid iron columns are used to hollow out from the inside and slowly thin out. Because of the high precision requirements, it can only be operated little by little. The more difficult it is to grasp the accuracy in the external direction, the slower the production progress of large thin-walled parts; there are also forged from the outside, because the large thin-walled parts are wide in the back and narrow in the front, so in the forging process, the shell wall is thinned and slowed down. Slowly move forward, the final thickness meets the requirements but the length has a ...
