Device and method for preparing circular pipes through high-deformation high strength alloy plates

Abstract

The invention discloses a device for preparing circular pipes through high-deformation high strength alloy plates. The device comprises a power supply system, a water tank and a water tank fixed plate connected with the upper end of the water tank, a boss is arranged in the water tank, and a plate material is arranged at the upper end of the boss. A forming mould is arranged at the upper end of the plate material, a vacuumizing device and a water adding device are arranged on the side of the water tank, and electrode fasteners are installed on the front wall and the rear wall of the water tank correspondingly. A discharge electrode is installed in each electrode fastener, one end of each discharge electrode is located in the water tank, and the other end of each discharge electrode is located outside the water tank. The tail ends of the two discharge electrodes are connected through a bridge wire in the water tank, and the other two tail ends of the discharge electrodes located outside the water tank are connected through the power supply system. The invention further discloses a preparation method for preparing the circular pipes through the high-deformation high strength alloy plates. According to the electro-liquid effect to prepare the circular pipes, formability of the plate material is improved, and the back-leap quantity of the circular pipes after bend forming is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and specifically refers to a device and a method for preparing round pipes from hard-to-deform high-strength alloy plates. Background technique [0002] With the vigorous development of my country's aviation industry and the start of the national large aircraft project, and with the improvement of environmental protection and energy conservation awareness, in the automotive industry, it is urgent to use high-strength steel to replace traditional low-carbon steel parts in automobiles. Reduce vehicle weight, thereby reducing oil consumption and greenhouse gas emissions. [0003] The more high-strength materials used in the aircraft industry are titanium and titanium alloys. Titanium and titanium alloys have many excellent characteristics, which are mainly reflected in the following aspects: 1) Higher specific strength, the tensile strength of titanium alloy is 686-1176Mpa, and the...

AI Technical Summary

Problems solved by technology

But so far, it is still difficult for some major titanium processing units in my country to produce aviation pipes that meet the standards. The main problems in the processing of titanium pipes are as follows: 1) The material processing technology is not solidified, and the deformation cannot meet the requirements. The microstructure of the pipe has not been sufficiently refined, 2) the pipe needs to be heat treated after cold working, which results in a coarse microstructure after heat treatment

[0011] To sum up, in view of the existing problems in the prior art for the preparation of high-strength round tubes, such as the deformation cannot meet the requirements and the process is cumbersome, the electro-hydraulic effect is applied to the preparation of difficult-to-deform high-strength alloy plates to prepare round tubes method came into being
