Semi-submersible type laser cutting method for high-speed aircraft empennage

Abstract

The invention provides a semi-submersible type laser cutting method for a high-speed aircraft empennage. The semi-submersible type laser cutting method for the high-speed aircraft empennage comprisesthe following steps that an empennage sample piece 12 is put into a fixture 3 and fixed and clamped; a working solution is added into a liquid groove 2, the lower surface of the empennage sample piece12 is immersed by the working solution, but the working solution does not exceed the upper surface of the empennage sample piece 12, and the specific immersing height is adjusted through the fixture;a cooling-water machine 1 is turned on, the temperature and the flowing speed are set, and by means of a filter 8, the constant temperature and the constant flowing speed of the working solution arekept among the liquid groove 2, the cooling-water machine 1 and a working solution storage tank 9; and according to the size of the empennage sample piece 12 and requirements, laser machining parameters are input, and a laser head 10 begins to carry out machining. According to the semi-submersible type laser cutting method, a high-power pulse laser is used for carrying out machining, the machiningefficiency is greatly improved, the empennage sample piece is semi-immersed in the working solution, the situation that laser beams direct beat the surface of the working solution, a sputtering phenomenon occurs, and unnecessary energy losses are caused cannot occur, meanwhile, the working solution flows on the lower part, cutting residues are brought away, a cutting face heat affected zone is also reduced, and high-precision, high-efficiency, low-cost and large-batch machining can be achieved.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, in particular to a semi-submersible high-power pulse laser cutting method for the empennage of a high-speed aircraft. Background technique [0002] As an important part of some precision-guided weapons or smart weapons, the empennage of high-speed aircraft is to provide lift for the flight of the projectile, generate a stabilizing moment, and ensure the stability of the flight of the projectile. The working environment of the high-speed aircraft tail is mostly extremely harsh, so high precision and high quality are required when processing the high-speed aircraft tail. At present, the commonly used processing methods in the field of empennage processing are: (1) mechanical cutting processing method, which has the advantages of stable quality and high efficiency, but the cutting process is complicated, and the utilization rate of materials is extremely low, the production cost is high, and r...

Problems solved by technology

At present, the commonly used processing methods in the field of empennage processing are: (1) mechanical cutting processing method, which has the advantages of stable quality and high efficiency, but the cutting process is complicated, and the utilization rate of materials is extremely low, the production cost is high, and resource consumption Serious; (2) Precision casting or die casting, although this method can improve the utilization rate of materials, the mechanical properties of the cast tail often fail to meet the requirements of use, and are prone to deformation and residual stress, and even cracking; (3) Water jet The main problem of the cutting method is that the cutting speed is slow, and it is necessary to continuously add abrasive materials to the high-pressure jet, which increases the manufacturing cost; (4) the wire EDM processing method can generally meet the machining accuracy requirements of the missile tail. It also has good tissue mechanical properties, but the main problem it faces is that the processing efficiency is too low to meet the needs of mass production
