Integral forming method of wide-width, high-strength, thin-walled metal panel

Abstract

The invention belongs to the technical field of compound forming of metal profiles, and in particular relates to an integral forming method of a wide-width, high-strength, thin-walled metal wall plate, which includes the following steps: (1) preparing a machined tube blank by using a spinning process or a cutting process; ( 2) Splitting and cutting; (3) Heat treatment before unfolding and straightening; (4) Expanding and straightening; (5) Subsequent process treatment. The purpose of the present invention is to make use of the advantages of the prior art to easily produce large-diameter, high-precision thin-walled cylindrical parts with outer transverse ribs, and utilize the integral forming method of wide-width, high-rib, thin-walled metal wall panels proposed by the present invention, combined with The invention relates to a device and method for unfolding and straightening arc sections of thin-walled cylindrical parts with outer transverse ribs, which can overcome many difficulties in the prior art in integral forming of wide-width, high-rib, and thin-walled metal panels. Solve the production problem of the overall forming of "wide-width, high-strength, thin-walled metal siding".

Description

technical field [0001] The invention belongs to the technical field of compound forming of metal profiles, and in particular relates to an integral forming method of wide-width, high-rib and thin-walled metal wall panels. Background technique [0002] In modern high-end manufacturing fields such as automobiles, ships, rail transit, and aerospace, high-strength, high-toughness thin-walled aluminum alloy sheets are widely used. In order to meet the performance requirements of high strength, good rigidity, and light weight of components, high-strength, high-toughness thin-walled aluminum alloy plates usually need to be fixed with reinforcing ribs. At present, there are mainly two methods of fixing high-strength and high-toughness thin-walled aluminum alloy plates and ribs, welding and riveting, which inevitably bring about problems such as heavy welding or riveting workload, overall weight gain, and low assembly efficiency. The overall forming technology of wide-width, high-st...
