Abstract

The invention discloses a method for adjusting the amount of spinning stagger of two spinning wheels. When setting the amount of thickness reduction of each spinning wheel, the amount of thickness reduction of each spinning wheel is determined according to work hardening of a material when three-spinning-wheel stagger spinning; according to a total amount T of thickness reduction, the number of the spinning wheels and a distribution value of the amount of thickness reduction at the time of stagger spinning of each spinning wheel, the amount of thickness reduction of each spinning wheel is obtained; and when adjusting the axial position of each of the spinning wheels, the spinning wheels are radially moved along a cylindrical member to a corresponding wall thickness reduction amount area ofa spinning blank to enable straight lines on which the sides of spinning angles alpha of the spinning wheels are located to be tangent to straight lines on which the sides of the spinning angle alphaof the first spinning wheel to obtain the amount of stagger between the spinning wheels, and the precision reaches a 0.01mm level. According to the method for adjusting the amount of spinning staggerof the two spinning wheels, a plurality of spinning wheels are equivalent to a stepped integral spinning wheel to realize stable deformation of the metal material; and when determining the amount ofstagger between the spinning wheels, the rebound of the material and equipment and work hardening caused by the distribution of the amount of thickness reduction of each spinning wheel are fully considered, the amount of stagger between the spinning wheels is consistent with the actual production, the characteristics of simple operation, quickness and convenience are achieved, and the efficiency is extremely high.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for adjusting the misalignment amount of spinning of two rollers. Background technique [0002] With the rapid development of my country's aviation, aerospace and other high-precision manufacturing industries and the national economy, there are more and more demands for thin-walled metal spinning cylindrical parts, and the precision requirements of parts are also getting higher and higher. Therefore, the requirements for the stability, applicability, scientificity and speediness of parameter selection for the powerful spinning process of cylindrical parts are getting higher and higher. [0003] The staggered pitch spinning can achieve a larger pass thinning rate in one spinning stroke, and the production efficiency is higher; if the staggered distance between the rollers is too large or too small, the quality of the spinning parts will be affected. If the amount of m...
