Laser cutting device with angle convenient to adjust and using method

Abstract

The invention provides a laser cutting device facilitating angle adjustment and a using method, and belongs to the technical field of laser cutting. The laser cutter is arranged at the side end of the butt joint pipe in parallel; the scanning tube is fixedly connected to the end side of the butt joint tube; the feeding pipe is fixedly connected to the end side of the scanning pipe, and a supporting plate is fixedly connected to the circumferential surface of the feeding pipe; a plurality of accommodating grooves are arranged; the tubular workpiece can be supported in an auxiliary mode, in the curved surface machining process of the tubular workpiece, the tubular workpiece needs to be rotated and meanwhile telescopically moved, the tubular workpiece is rotated through the multiple rolling rods while materials are fed, the tubular workpiece between the multiple rolling rods is rotated, synchronous rotation is achieved, and the machining efficiency is improved. The cutting angle and position between the tubular workpiece and the laser cutter are changed, rotation angle adjustment is provided for the cutting process of complex textures, and therefore the conditions that the textures are not uniform after machining, errors exist and the like are avoided.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and in particular relates to a laser cutting device and a using method which are convenient for adjusting an angle. Background technique [0002] Laser cutting is the use of a focused high-power-density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, and at the same time the molten material is blown away by the high-speed airflow coaxial with the beam, so as to realize the cutting of the workpiece. Open, laser cutting is one of the thermal cutting methods. [0003] During the laser cutting process of tube-shaped workpieces, the tube-shaped display is on a curved surface. The existing laser cutting device is not suitable for processing tube-shaped workpieces, and cannot adjust the rotation angle of tube-shaped workpieces, resulting in uneven texture and errors after processing. At the same time, the ...

[0003] During the laser cutting process of tube-shaped workpieces, the tube-shaped display is on a curved surface. The existing laser cutting device is not suitable for processing tube-shaped workpieces, and cannot adjust the rotation angle of tube-shaped workpieces, resulting in uneven texture and errors after processing. At the same time, the laser cutting device does not have the function of automatically finding the midpoint, and cannot automatically locate the laser, resulting in serious burrs and flanging. Therefore, we propose a laser cutting device and its use method that are easy to adjust the angle
