Problems solved by technology

When the ordinary spinning method is used to process large workpieces, there are problems such as the mandrel is too large, it is difficult to expand the processing range, and the cost of the mold is high. The wheel spinning technology can solve these problems very well.
However, the existing wheel spinning method has the problem of difficult adjustment of the inner wheel, so it is difficult to apply on a large scale

Abstract

Provided is a flexible opposite roller spinning alternating current servo direct drive structure. Horizontal synchronous feed movement of internal spinning rollers and external spinning rollers is achieved respectively by utilizing a servo motor to drive screw rods, the internal spinning rollers and the external spinning rollers perform longitudinal movement by electric cylinder driving, and the whole processing process is finished under the control of a servo system. Horizontal synchronous feed of the internal spinning rollers, horizontal synchronous feed of the external spinning rollers and longitudinal asynchronous feed of the spinning rollers can be achieved in the opposite roller spinning process, complex workpiece processing can be finished, workpiece positions can be controlled in real time in a mode of adopting the servo motor to drive the screw rods and an electric cylinder driving mode, and the flexible opposite roller spinning alternating current servo direct drive structure is convenient to operate and large in applied range and overcomes the shortcoming that opposite roller spinning position adjustment is invariable.

Description

technical field [0001] The invention belongs to the technical field of processing large-scale thin-walled rotary parts, and in particular relates to an AC servo direct drive structure for flexible spinning on opposite wheels. Background technique [0002] The processing of large thin-walled rotary parts has always been an important task in the aviation, military and other manufacturing industries. For thin-walled rotary parts, spinning processing technology has outstanding advantages: high production efficiency, high product precision, simple process, and the ability to produce seamless rotary parts. When the ordinary spinning method is used to process large workpieces, there are problems such as too large mandrel, difficulty in expanding the processing range, and high mold cost. The counter-wheel spinning technology can solve these problems well. However, the existing counter-wheel spinning method has the problem of difficult adjustment of the inner wheel, so it is difficu...
