Laser bevel cutting head

Abstract

The invention relates to the technical field of processing steel plate bevels, particularly disclosing a laser bevel cutting head, comprising a DD motor A (1), a C-axis microscope base (2), a counterweight body (3), a DD motor B (4), a B-axis microscope base (5), an anti-collision device (6) and a laser cutting head (7), wherein, the DD motor A (1) is used for driving along the axis C; the counterweight body (3) is used for balancing the deflection torque of the laser cutting head on the axis B; and the DD motor B (4) is used for driving along the axis B. The laser bevel cutting head of the invention adopts direct-drive hollow shaft motor structure to lower the failure rate, and can be used for processing various unilateral V-shaped and I-shaped bevels at the range of 45 degrees; and the processed fracture surface has high quality, can be directly used for welding, and does not need secondary processing and polishing, thus greatly improving the processing efficiency.

Description

technical field [0001] The invention relates to the technical field of steel plate bevel processing, in particular to a laser bevel cutting head device. Background technique [0002] In the manufacturing process of shipbuilding, engineering machinery, oil pipelines, etc., according to the design or process requirements, the groove processing of thick steel plates has always been an essential process. It is processed and assembled into a certain geometric The groove of the shape, the purpose of opening the groove is to obtain a fully penetrated weld in the thickness of the weldment. Commonly used groove forms include I-shaped groove, V-shaped (with blunt edge) groove, U-shaped (with blunt edge) groove, X-shaped (with blunt edge) groove, and single-sided V-shaped (with blunt edge) groove. Groove and K-shaped (with dull edge) groove. [0003] At present, flame and plasma processing methods are generally used. Because this processing method will produce deep cut marks, the den...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: laser processing is a new type of groove processing method with the smallest thermal deformation and the best incision quality. V-shaped and I-shaped bevels, the bevel processing completed by traditional cutting, milling and other multiple processes is completed at one time, which greatly improves efficiency, ensures quality, and saves resources. The quality of the cut parts is high, the dimensional accuracy is high, and the surface is high. quality
