Embodiment

[0016] Purchase 4mm TC4 titanium alloy plate, remove oil and dust on the surface, position the plate, debug laser related equipment, check whether the cutting head lens needs to be replaced, whether the cutting nozzle is damaged, adjust the defocus, set the manipulator parameters, prepare argon gas, and cut the process The parameters are: cutting speed is 3m / min; laser power is 3.5kW; gas pressure is 2.0MPa; defocus is -3mm; working distance is 0.8mm; cutting nozzle diameter is 2.5mm; cutting gas is argon. Prevent the cutting head from hitting obstacles during the cutting process, and keep away from flammable objects during the cutting process to ensure equipment and personal safety.

Abstract

The invention relates to a method for cutting a 4 mm titanium alloy by laser. The method comprises the following steps of removing oil stains and dust on the surface of the titanium alloy, and keeping the surface of the titanium alloy smooth; and adopting a ProCutter laser cutting gun for cutting a 4 mm titanium alloy, wherein the process parameters are that the cutting speed is 2-4 m / min, the laser power is 3-4 kW, the gas pressure is 1.5-2.5 MPa, the defocusing amount is -4 mm to -1 mm, the working distance is 0.6-1.0 mm, the diameter of a cutting nozzle is 2.0-3.0 mm, and the cutting gas is argon. When the method is used for cutting the titanium alloy, a cutting process window which is free of adhering slag on the back face of a kerf and good in kerf quality and the optimal cutting process parameters are obtained by changing all the process parameters, the process stability is guaranteed, and repeatability is achieved.

Description

technical field [0001] The invention relates to a method of laser cutting 4mm titanium alloy, in particular to a cutting method of laser cutting + 4mm titanium alloy plate + argon gas. Background technique [0002] TC4 titanium alloy is a dual-phase alloy with good comprehensive properties, good structural stability, good toughness, plasticity and high-temperature deformation properties, and can be processed by hot pressure well, and can be quenched and aged to strengthen the alloy. The strength after heat treatment is about 50% to 100% higher than that of the annealed state; the high temperature strength is high, and it can work for a long time at a temperature of 400°C to 500°C, and its thermal stability is inferior to that of α-titanium alloy. [0003] Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. In addition, the process performance of titanium alloy is poor, and it is difficult to cut and process....
