Novel spinning machine structure and spinning method

Abstract

The invention discloses a novel spinning machine structure and a spinning method, belonging to the field of machinery. The novel spinning machine structure comprises a spinning core mold rotating mechanism and a spinning core mold longitudinal moving mechanism, wherein a spinning core mold is sleeved with a spinning blank, the spinning blank is coaxially arranged above the spinning core mold rotating mechanism, the spinning core mold longitudinal moving mechanism is located below the spinning core mold rotating mechanism, a spinning roller head is transversely arranged on the periphery of the spinning core mold, the spinning core mold rotating mechanism serves as a rotating power source of the spinning core mold through a worm and gear power input system, and the spinning core mold longitudinal moving mechanism controls a piston through a hydraulic pump to serve as a power source of longitudinal displacement of the spinning core mold. According to the spinning machine structure, a longitudinal moving mechanism of the spinning roller head is omitted and the spinning roller head only rotates around a shaft, so the size of a spinning machine is reduced by 70%; and due to the fact that the spinning roller head does not move any more, the sliding friction force of a longitudinal rail and the lubrication problem of guide rails do not need to be considered; and a spinning process is completed through rotation and longitudinal movement of the spinning core mold.

Description

Technical field [0001] The present invention belongs to the mechanical field, particularly relates to a novel structure and a spinning machine spinning method. Background technique [0002] Spinning technology widely used in the production of aircraft, rockets and other fields, may be formed as a cylindrical, conical, parabolic form or other in vitro rotational various curves constituted quite complicated shapes can be processed rotating body parts. The basic principle of the spinning machine is spinning mandrel rotation knob while applying a certain force to move longitudinally blank and the blank longitudinally extending spinning. [0003] The spinning spindle position, into the existing spinning machine spinning machine such as a vertical figure 1 And horizontal spinning machine as figure 2 Two kinds, their common feature is that the spinning mandrel mounted on the faceplate only rotational movement of the headstock, the knob must be moved along the mandrel longitudinal axis. ...

AI Technical Summary

Problems solved by technology

The power source required to drive the rotary wheel to move longitudinally along the core mold axis takes up a lot of space, and the sliding friction between the guide rail and the ram cannot be stably controlled when moving axially, the power source consumes a lot of energy, and at the same time generates a lot of noise
