Process method for transversely rolling pipe

Abstract

The invention discloses a process method for transversely rolling a pipe, which comprises the steps of providing a core rod and a plurality of spinning rollers arranged around the core rod in the circumferential direction, wherein the spinning rollers are constructed to be capable of rotating around the core rod in the circumferential direction; pushing a pipe blank sleeving the core rod so as to enable the pipe blank to be fed towards a spinning roller in the axial direction of the core rod; when the front end of the pipe blank passes through the spinning roller, enabling the spinning roller to be tightly attached to the outer wall of the pipe blank and rotate in the circumferential direction of the pipe blank so as to apply pressure to the front end of the pipe blank to be thinned to form a machined section; and clamping the machined section passing through the spinning roller, drawing the pipe blank to continuously pass through the spinning roller, and meanwhile, enabling the spinning roller to continuously rotate around the pipe blank in the circumferential direction so as to apply pressure to the remaining part of the pipe blank, and thinning the remaining part of the pipe blank. The spinning and drawing machining processes are combined, so that the machining efficiency is improved, and meanwhile, the metal plastic forming performance can be guaranteed; and waste materials are not generated, and the structure and mechanical properties of the pipe are remarkably improved through metal plastic flowing and extrusion.

Description

Technical field [0001] The present invention relates to the field of metal processing, and more particularly to a transverse rolling tube process. Background technique [0002] For pipe processing, commonly drawn, strong rotation, hot rolling and other processing processes. Among them, the drawing and rotation can have a great improvement of the performance of the pipe fitting, and the draw is mainly for a good plastic, and the modified metal, the rotary press processing can be wide, but its efficiency is low. Therefore, in order to ensure the efficiency and the processing range, it is necessary to improve and innovate existing processing equipment. Inventive content [0003] According to one aspect of the invention, a transverse rolling tube process is provided, including the following steps: [0004] The mandrel is provided and a plurality of swirls arranged around the mandrel along the circumferential direction, and the rotary wheel is configured to rotate circumferential rot...
