Abstract

The invention discloses an induction heating torsion system and a method using the induction heating torsion system for torsion heating. The induction heating torsion system comprises a base, a clamping device, an induction coil, a sliding device, a driving device and a torsion device, wherein the clamping device comprises an induction clamping head and a torsion clamping head, the torsion device comprises a rotary shaft, the induction clamping head is fixedly arranged on the base, the rotary shaft is rotatably arranged on the base, the torsion clamping head and the end part of the rotary shaft are fixed, the torsion clamping head is slidingly connected with the base, the center of the induction clamping head is provided with a clamping port, a part penetrates through the induction coil, the head end of the part is detachably and fixedly arranged on the torsion clamping head, the induction coil is connected with a central controller, and the driving device is respectively connected with the central controller, the torsion device and the sliding device. The induction heating torsion system has the advantages that the structure is simple, the size is small, the cost is low, the weight is light, the torsion is more uniform, the local deformation of the part is precisely controlled, the processing efficiency is high, the finished rate of the part is high, and the maintenance and the replacement are convenient.

Description

technical field [0001] The invention relates to a heating system, in particular to a titanium alloy hollow blade induction heating torsion system applied to aircraft engines and aircraft engines. [0002] The present invention also relates to a heating method, in particular to a method of torsion heating using the above-mentioned induction heating torsion system, especially a method of using the above-mentioned induction heating torsion system to perform torsion heating to prepare aircraft engines and titanium alloy hollow blades of aircraft engines. Background technique [0003] At present, the preparation of general titanium alloy hollow blades is generally made by casting or whole heating and twisting. The process of casting preparation is simple, and the weight of the castings is large, so that the energy consumption of the engine is relatively large, and the effective output is small. In addition, the castings may have trachoma, slag inclusions, and internal cracks, whi...
