Abstract

The invention discloses a manufacturing method of a metal plate. A plate is obtained by spinning to mold a cylinder, splitting and flattening along the bus direction of the cylinder. One-pass or multi-pass spinning process is adopted; when multi-pass spinning is carried out, in order to recover the plasticity of materials to facilitate continuous spinning, thermal treatment is adopted during two passes so as to improve the material plasticity and reduce processing hardening; when final-passing spinning is carried out, in order to control the wall thickness of the spinning cylinder to be within the qualified range, a test spinning method is adopted, so that a plate meeting the requirement can be met. Because materials are subjected to plastic deformation, the mechanical performance is improved, so that performance of the plate subjected to flattening is superior to the performance of a cylinder blank before spinning. The manufacturing method of the metal plate is suitable for manufacturing plates with high precision and special wall-thickness specification, and can be used for manufacturing metal plates with different specifications flexibly.

Description

technical field [0001] The invention relates to the machinery manufacturing industry, in particular to a method for flexibly manufacturing metal plates of different specifications. Background technique [0002] With the continuous development of the machinery manufacturing industry, the demand for sheet metal specifications is becoming more and more diverse. In particular, the market is difficult to meet the individual needs of plates with different thickness specifications. Using traditional cold and hot rolling methods to manufacture plates is often aimed at mass production, and the production cycle is long. The invention with the publication number CN103820717A discloses a steel plate and its preparation method, and introduces a steel plate obtained by optimizing the smelting process of the steel so that the obtained steel plate has an excellent chemical element ratio. Through smelting, continuous casting, rolling, heat treatment and other processes, low-cost and easy-t...
