Abstract

The invention discloses a method for controlling the electrothermal stretch bending process of titanium alloy profiles and a stretch bending forming device. The control includes: clamping the titanium alloy profiles and fixing the copper plate on the suspended section of the titanium alloy profiles; heating the titanium alloy profiles; heating the titanium alloy profiles; When the alloy profile reaches the first set temperature, pre-stretch and bend the titanium alloy profile; when the bending of the titanium alloy profile ends, increase the heating current, wherein the temperature of the suspended section of the titanium alloy profile is lower than that of the titanium alloy profile The temperature of the bending section; when the bending section of the titanium alloy profile is heated to the second set temperature, the titanium alloy profile is stretched and deformed. The purpose of the control method for the electric heating stretch bending process of titanium alloy profiles is to solve the problems of low efficiency and high cost of the traditional titanium alloy profile heating stretch bending process.

Description

technical field [0001] The invention belongs to the technical field of metal forming, and in particular relates to a control method and a stretch bending forming device for a titanium alloy section bar electrothermal stretch bending process. Background technique [0002] The application of carbon fiber reinforced composite fuselage structures in advanced civil and military aircraft is gradually increasing. Titanium alloy materials are more and more used in advanced aircraft due to their potential compatibility and impact resistance with composite materials. Titanium alloy forging, machining and heat treatment quality control is difficult and costly. Titanium alloy curved profiles have become the main structure of composite fuselage load-bearing components, and are used in fuselage load-bearing frame girders, central wing boxes, and main landing gear gears. Mechanism brackets, and door frames, etc. Therefore, the forming quality of titanium alloy profile bending parts is dire...
