Abstract

The invention discloses a method for adjusting the spinning staggered distance amount of three spinning wheels. When the thinning amount of each spinning wheel is set, the thinning amount of each spinning wheel during staggered distance spinning of the three spinning wheels is regulated according to machining hardening of materials. According to the total thinning amount T, a number of the spinning wheels, and a thinning amount allocation value during staggered distance spinning of each spinning wheel, the thinning amount of each spinning wheel is obtained. When the axial position of each spinning wheel is adjusted, the spinning wheels are moved to corresponding wall thickness thinning amount areas of a spinning blank in the radial direction of a cylindrical part, so that the straight linewhere the a edge of a screw-in angle of each spinning wheel is located is tangential with the straight line where the a edge of a screw-in angle of a first spinning wheel is located, the staggered distance amount between the spinning wheels is obtained, and the precision reaches 0.01 mm level. According to the method, the plurality of spinning wheels are equivalent to a step type overall spinningwheel, and stable deformation of a metal material is achieved; and when the staggered distance amount between the spinning wheels is determined, machining hardening caused by springback of the materials and equipment and allocation of the thinning amount of the spinning wheels are fully considered, and is matched with actual production, the beneficial effects that operation is easy, fast and convenient are achieved, and 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 three-wheel spinning. 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 misa...
