Laser pipe cutter with 3D bevel cutting function and control method

Abstract

The present invention discloses a laser pipe cutter with 3D bevel cutting function and a control method; a spindle box and a front chuck are both installed on a same pair of linear guide rails of a main machine tool, to maintain and adjust the spindle box and the front chuck concentrically; the spindle box and the front chuck are used to clamp a pipe, so that the pipe, the spindle box, and the front chuck rotate synchronously; the clamping jaw of the spindle box is configured to clamp the pipe to move along the X axis of each linear guide rail, and the rollers of the front chuck are configuredto support the pipe, so that the pipe smoothly moves along the X axis under the support of the front chuck roller, at the same time, the front chuck can also move along the X axis to keep away from the laser cutting head when the pipe 3D bevel is cut; a 3D laser cutting head is installed on the bottom plates of the upper and lower mechanisms on the Z axis; by controlling the motion of the upper and lower mechanisms on the Z axis, the bottom plates of the upper and lower mechanisms on the Z axis and the 3D cutting head move up and down; in the present invention, the 3D bevel of the pipe is cutthrough 5-axis interpolation motion, and the pipe tail material is shortened in length and even the tail material is absent from the pipe.

Description

technical field [0001] The invention relates to a laser pipe cutting machine with 3D bevel cutting function and a control method, in particular to a laser pipe cutting machine, which can realize five-axis interpolation motion to cut the 3D bevel of the pipe, and shorten the length of the tail of the pipe at the same time Even zero tailings. Background technique [0002] Generally, the 2D laser pipe cutting machine can be used for blanking, cutting holes and cutting grooves of closed pipes. Since the laser cutting head in the equipment cannot be deflected, the laser cutting head can only cut perpendicular to the surface of the pipe, so the section of the pipe blanking, cutting hole and cutting bevel is also vertical. At this time, if two or more parts with vertical sections are joined together, there will be a large gap at the joint, which cannot meet the needs of some production. At the same time, when cutting materials at 2D grooves, common-edge cutting cannot be performe...
