Abstract

The invention relates to opposite roller spinning equipment, in particular to opposite roller spinning equipment for forming a large thin-walled cylindrical part, and aims to solve the problems that existing die spinning equipment is high in cost, poor in universality and long in manufacturing period as a core die is needed. A chuck substrate fixing base is installed on a rack between an internal rotation guide rail and an external rotation guide rail, a chuck substrate is installed on the chuck substrate fixing base, an external rotation mechanism fixing base is installed on the external rotation guide rail in a sliding mode, and an external rotation disc is installed on the external rotation mechanism fixing base; a bottom plate is installed on an internal rotation guide rail, a lifting motor is installed at the lower end of the bottom plate, one end of a lifting lead screw penetrates through the bottom plate, and the other end of the lifting lead screw is connected with a base; an internal rotation device fixing base is installed on the bottom plate, a worm and gear assembly is installed on the chuck substrate, a three-claw chuck is installed on the worm and gear assembly, multiple pull rods are connected with the external rotation disc, the chuck substrate and the base, an internal rotation device is installed in the internal rotation device fixing base, and the external rotation device is installed in the external rotation disc. The opposite roller spinning equipment is suitable for carrying out opposite roller spinning on the large thin-walled cylindrical part.

Description

technical field [0001] The invention relates to a counter-wheel spinning equipment, in particular to a counter-wheel spinning equipment for forming large thin-walled cylindrical parts. Background technique [0002] Through the comparison and analysis of several existing large-diameter and thin-walled cylinder forming processes, a process for ultra-large-diameter thin-walled cylinders—counterwheel spinning is proposed. In this process, the traditional mandrel is replaced by a rotary wheel, and the inner and outer surfaces of the cylindrical part are formed simultaneously, without being limited by the diameter, wall thickness and length of the large-sized cylinder. It is of great significance for the production of ultra-large-diameter thin-walled cylinders, and is the main method for forming large-diameter cylinders in the future. Especially in the manufacture of large-diameter thin-walled cylindrical parts, the existing molded spinning equipment has the problems of high cost...
