Composite sheet metal spinning machine and spinning method thereof

Abstract

The invention discloses a composite sheet spinning machine and spinning method. The composite sheet spinning machine comprises a main drive motor, a motor box, a spindle box, a tail top assembly, a main feed guide rail, a tail top drive assembly, a tail top saddle, a tail top saddle sliding board, a tail top guide rail, a mandrel, supporting legs, a main motor base, a base, a lathe bed, a forming spinning roller axial drive assembly, a forming spinning roller saddle, a forming spinning roller radial drive assembly, a forming spinning roller frame, a forming spinning roller, a forming spinning roller saddle sliding board and a spinning roller sliding board guide rail. The composite sheet spinning machine integrates ordinary spinning and mandrel-free spinning, use and combined machining of two different machining modes are achieved on one machine, the machining of two different modes can be finished only by controlling the feed direction of a motor through easy operation, the structure is compact, operation is easy and convenient, the cost of the machine is low, and the machining flexibility is good.

Description

technical field [0001] The invention relates to the field of composite spinning machines, in particular to a composite sheet metal spinning machine and a spinning method suitable for processing curved surface parts under two processes of ordinary spinning and coreless spinning. Background technique [0002] Metal spinning forming is a processing technology for hollow and axisymmetric workpieces, which makes the blanks squeeze and deform point by point and apply films. The advantages of small loading force, work hardening, chip-free forming, and seamless processing make it widely used in many fields such as military industry and aerospace. [0003] In ordinary spinning, the geometry of the workpiece is determined by a rigid axisymmetric mandrel. With the development of industrial technology, the shape of the workpiece tends to be complex, requiring a special core mold, and the molding process is cumbersome, which undoubtedly increases the cost of the workpiece and the proces...

Problems solved by technology

In addition, there are fewer dedicated coreless spinning machines at this stage

In order to meet the increasingly diverse and complex processing needs, spinning processing enterprises have to configure ordinary spinning machines and special coreless spinning machines at the same time, and the initial machine cost is high.
