Hydraulic spin forming machine

Abstract

A hydraulic spin forming machine comprises a base, an oil cylinder bracket on the base, an oil cylinder, an oil cylinder push frame, a sliding sleeve, a main shaft in the sliding sleeve, a movable bearing sleeve outside the sliding sleeve, a gear bearing sleeve and a gearwheel. The outer wall of movable bearing sleeve is articulated with a rotation compression rod through the other end of connecting rod articulated with the outer wall of movable bearing sleeve. The other end of rotating pressure lever is articulated with a spin outer wheel and is matched with a spin inner wheel installed at the end part of main shaft. The using of the forming machine introduces the spin forming technique to the classroom and creates condition for the application and development of spin technique. The forming machine adopts a trolley planetary rotation without the movement of workpiece. The swing feeding movement is realized through impelling the rotating feed wheel by the oil cylinder. The forming machine can be used for spinning the rectangular tube and curved tube.

Description

【Technical field】: [0001] The invention belongs to the technical field of metal machining equipment, in particular to a metal spinning forming machine. 【Background technique】: [0002] Metal spinning means that the workpiece is rotated so that the stress point is from point to line and from line to surface, and at the same time, a certain pressure is given by a hob in a certain direction to make the metal material deform and flow along this direction to form a certain shape. A shape technique. Here, the metal material must have plastic deformation or flow properties. Spinning is not equivalent to plastic deformation. It is a complex process of plastic deformation and flow deformation. Due to the advanced nature, economy and practicality of the spinning process, and the process has the characteristics of small deformation force and saving raw materials, in the past forty years, the spinning technology has made great progress, not only in the field of aerospace, but also It ...

AI Technical Summary

Problems solved by technology

my country's spinning technology began in the early 1960s. After decades of hard work, my country's basic research on spinning technology equipment and spinning technology (such as stress-strain finite element analysis of spinning process, new technology and new methods) and theoretical exploration and research) have made a lot of progress, making spinning technology more and more widely used, but still can not meet the needs of my country's national economic development
