Laser welding equipment Use in motor stator core operation

Cold rolled or hot-rolled silicon steel sheet is generally selected as the lamination material of motor stator, and its weldability is excellent. For example, compared with tungsten argon arc welding, it not only improves the production rate, but also improves the health and safety conditions of production environment, and eliminates the personal damage caused by strong arc light, ozone and other bad oxides during argon arc welding. In addition, the computer can be used to control the output laser beam of two or four machines or single machine with multiple heads, which can be placed around the outer circular wall of the stator. In this way, the number of welds required for tightening the stator can be completed once or twice, which can not only greatly reduce the deformation, but also save the processing time. The following describes the application of laser welding equipment in the operation of motor stator core.

In the structure of the motor, the iron core (magnetic core) plays an insignificant role. It is used to increase the magnetic flux of the inductance coil, which has ended the maximum conversion of electromagnetic power. The iron core is usually composed of a stator and a rotor. Welding of motor rotor shaft and rotor shaft compression ring the circumferential weld between motor rotor shaft and compression ring generally adopts CO2 gas maintenance welding or tungsten argon arc welding. The welding has large deformation and large heat affected zone. The heat generated by welding will also affect the magnetic steel in the assembled motor body. The method of selecting laser welding equipment has the advantages of energy convergence, high density, high heating efficiency and fast speed. Therefore, the deformation of base metal is small and the heating effect of metal in non melting zone is small. Wuhan Ruifeng photoelectric laser welding equipment is cost-effective. With many years of laser development experience, the product skills are mature and the product function is safe and stable. The company follows the operation concept of "innovation in skills, products and services" to provide customers with the best quality products and services.

The production process of motor iron core of laser welding equipment mainly includes several processes such as stamping, punching classification and stacking, and touches the main flow processes such as riveting method, welding method and buckle method. Sealing welding of motor aluminum alloy shell rivets or bolts are generally used for the connection between motor aluminum alloy shell and fuselage, so it is necessary to add washers between motor shell and fuselage to achieve sealing effect. The sealing effect of this method will be weakened with the aging and damage of the gasket, which will affect the overall function of the motor. Assuming that the method of seamless welding instead of riveting or bolt connection can not only reduce the weight of the fuselage and shorten the production cycle, but also obtain excellent sealing function.

The traditional welding process of motor core has defects, such as defective appearance and rough weld. High requirements for workers' operation, large disturbance caused by human factors, etc. Cold rolled or hot-rolled silicon steel sheet is generally selected as the lamination material of motor stator, and its weldability is excellent. For example, compared with tungsten argon arc welding, it not only improves the production rate, but also improves the health and safety conditions of production environment, and eliminates the personal damage caused by strong arc light, ozone and other bad oxides during argon arc welding. In addition, the computer can be used to control the output laser beam of two or four machines or single machine with multiple heads, which can be placed around the outer circular wall of the stator. In this way, the number of welds required for the tightening of the stator can be completed once or twice, which can not only greatly reduce the deformation, but also save the processing time.
