Machining method of workpiece welding groove-workpiece rotary type numerical control cutting machine

Abstract

The patent of the invention relates to an innovative numerical control cutting machining method aiming at (sheet metal) workpiece welding grooves, which is a cutting application method combining blaze, plasma and flying optics laser and belongs to the field of industrial welding and cutting technology. The invention adopts a machining mode that workpiece actively rotates, the workpiece can be freely clamped, the invention is suitable for numerical control cutting machining of the welding groove with any curved profiles, the cutting quality, the production efficiency and the material utilization are obviously enhanced, and the device cost is low. The invention adopts the mode that the workpiece revolves around tools (cutting torch) to rotate, thoroughly solves the technology bottlenecks of complex structure (winding and restrictions of connecting cables, gas pipelines, and the like of the cutting torch caused by the rotation of the workpiece) of traditional numerical control cutting method, and the like. The technical implementation scheme is that a workpiece active (unlimited) rotary disk arranged on a substrate loads the workpiece; each axis (A, X, Y, W and Z) of the numerical control procedure control system moves the edge of the workpiece groove to a cutting zone, and cutting torch (Z) axis automatically falls downwards to a working height and completes initial cutting gesture according to groove angle and thickness of the programming workpiece; and the workpiece (W) placed on the unlimited rotary disk is continuously matched with the cutting torch to swing (A) to do transverse (X) and longitudinal associated movement after a numerical control cutting processing program is operated, and the cutting torch is placed in a normal section of a cut workpiece all along and completes processing molding of the welding groove of the workpiece. The invention can be widely applied and popularized in industrial welding and cutting field.

Description

Technical field [0001] The patent of the present invention is an innovative numerical control cutting processing method for (metal plate) workpiece welding grooves, which can be combined with cutting applications of flame, plasma, and flying optical path lasers. It belongs to the technical field of industrial welding and cutting. Background technique [0002] At present, the traditional coordinate CNC cutting machine generally uses the cutting torch to cut perpendicular to the plate workpiece (commonly known as: blanking). For cutting torch processing, these traditional methods use the workpiece to be fixed, and the tool (cutting torch) moves around the workpiece, and there are many disadvantages as follows: [0003] ① When manual or semi-automatic trolleys are used to complete the straight line or curved welding groove processing on the edge of the workpiece contour, the motion track control is very complicated and the quality is difficult to guarantee; [0004] ② When us...
