Double support pipe cutting equipment

Abstract

The invention relates to a double support pipe cutting equipment, comprising a frame and a feeding mechanism; the frame is provided with a supporting mechanism for bearing incoming materials of the pipe and a cutting mechanism for processing the cutting seams of the pipe; the supporting mechanism comprises a first supporting seat fixed on the frame and a first clamp for clamping the pipe; the cutting mechanism comprises a cutting guide rail, a cutting bracket and a pushing mechanism; the cutting bracket is provided with a laser cutting head positioned above the pipe; the feeding mechanism comprises a feeding guide rail fixed on a machine tool and a second supporting seat arranged on the feeding guide rail in a sliding manner; the supporting seat is provided with a second clamp which is strictly aligned with the first clamp and rotates synchronously with the first clamp; and when the second clamp moves forward and backward, the first clamp and the second clamp alternatively clamp the cut pipe. The double support pipe cutting equipment can keep constant for the central position of the pipe in the processing process, can lead the pipe to be fed automatically, can carry out processingto a whole pipe without pipe waste materials, and has high processing precision and high production efficiency.

Description

technical field

[0001] The invention relates to a machine tool for pipe cutting, in particular to a double-support pipe cutting device. Background technique

[0002] Existing pipe cutting equipment mainly includes a chuck for clamping pipes and a cutting mechanism (laser cutting or mechanical cutting can be used). When cutting pipes, the following problems are often encountered:

[0003] 1. The pipe is long and heavy. Traditional cutting machine tools (whether laser cutting or mechanical cutting) usually clamp one end of the pipe, and the other end is supported by a floating support. Laser processing needs to cut a seam twice to complete. After the first cut, the pipe is rotated and indexed. However, the pipe is long and heavy, and it is prone to deflection. The center position of the pipe is shifted, resulting in laser focus or tool The position relative to the pipe also shifts accordingly, resulting in uneven distribution of the slits in the circumferential direction of t...
