A plate laser cutting machine for electric power equipment production

Abstract

The invention discloses a plate laser cutting machine for electric power equipment production, which comprises a cutting frame and a laser cutting head. The side beam is equipped with a gantry adjustment mechanism; the laser cutting head includes a slidable base and a laser emitter. The laser emitter includes an optical fiber connection block for external optical fibers. The front end of the optical fiber connection block is equipped with a collimator for beam direction adjustment The component module, the beam emitting end of the collimation component module is connected with a continuous zoom mechanism, the outer surface of the collimation component module and the continuous zoom mechanism is wrapped with a protective mirror box, and the front end of the protective mirror box is inlaid with a cutting nozzle; the invention can realize high precision Continuous and rapid zooming, by adjusting the size of the laser beam exit spot, it can realize the cutting of plates with different thicknesses, and can accurately adjust the three-dimensional position, which is suitable for metal plate cutting with complex requirements, with fast cutting speed and high efficiency.

Description

technical field [0001] The invention relates to the field of cutting machines, in particular to a plate laser cutting machine for electric power equipment production. Background technique [0002] The production of power equipment requires a large number of metal sheets and other materials. In order to meet the application requirements under different conditions, different sheets need to be cut. The efficient and environmentally friendly cutting device in the cutting operation is the laser cutting machine. The laser cutting machine is The laser emitted from the laser is focused into a high power density laser beam through the optical system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a s...

AI Technical Summary

Problems solved by technology

[0006] (1) Although the cutter can achieve continuous cutting of the workpiece to be processed, the device does not have a zoom function, so the focus and spot size of the output beam cannot be adjusted as required for workpieces with large thickness differences, resulting in low cutting efficiency ;

[0007] (2) Although the device has bearings in three directions to adjust the position of the probe, it is adjusted by the rotation of the screw, which has limited precision and poor stability
