Portable unlimited rotary numerical control beveled opening pipe cutting machine and beveled opening processing method

Abstract

The invention discloses a portable unlimited rotary numerical control beveled opening pipe cutting machine, which comprises a machine frame, a processing component, a bearing component and a numerical control system, wherein the machine frame is used for assembling sectional materials, the processing component and the bearing component are arranged on the machine frame, the numerical control system controls the processing component and the bearing component, the bearing component comprises a chuck seat and a chuck used for clamping a workpiece to be processed, the processing component comprises a transverse arm and a rotary arm with at least one bending part, the transverse arm and the rotary arm are connected through a rotary motor, the lower end of the rotary arm is connected with a cutting gun disc through an included angle connecting element, the rotary motor can drive the rotary arm to rotate so that the lower end of the rotary arm does circumferential movement around the rotating axial line of the rotary arm, in addition, the cutting gun disc is driven to rotate through the included angle connecting element, and a longitudinal guide rail used for the chuck seat to move on and a vertical guide used for the transverse arm to vertically move on are arranged on the machine frame. The invention also discloses a beveled opening processing method, i.e. a method for cutting a pipe fitting by using the pipe cutting machine. The beveled opening pipe cutting machine disclosed by the invention has the advantages that the structure is simple and clear, the shape processing of the pipe beveled opening is accurate, and the processing efficiency is extremely high. The beveled opening processing method has the advantages that the work procedure is simple, and the control is convenient.

Description

technical field

[0001] The invention relates to equipment for processing pipe fittings, in particular to a pipe cutting machine for processing pipe fitting grooves, and also relates to a method for processing pipe fitting grooves. Background technique

[0002] Most of the small pipes are threaded with pipe joints, while large pipes are usually welded to meet the requirements of different design pipelines, such as the cross intersections or T-shaped joints of pipelines, due to the inconvenience of making pipe joints. The pipe groove is the basis of pipe welding, so the quality of the groove processing greatly affects the welding quality of the pipe. Whether the groove is neat and the deviation from the design shape directly affects the welding quality. The bevel of a large pipe is the shape produced by the interpenetration of two pipes, usually an intersecting line formed by the intersection of two cylinders, and a certain bevel angle is required at the bevel to facilitate th...
