A laser tube cutting device

Abstract

The invention belongs to the technical field of laser cutting, and more specifically relates to a laser tube cutting device, which includes a cutting head, a bed, a first chuck, a second chuck, and a third chuck that are slidably arranged on the bed in sequence, The cutting head is slidingly connected with the bed; the first chuck is a fixed chuck for axial and radial positioning of the pipe fittings, the second chuck is a rolling chuck for radial positioning of the pipe fittings, and the third chuck The two ends of the disc are respectively provided with a fixed chuck for axial and radial positioning of the pipe, and a rolling chuck for radial positioning of the pipe. The fixed chuck is close to the second chuck, and the rolling chuck is far away from the second chuck. In this solution, the third chuck integrates the double clamping function of rolling clamping and fixed clamping, so as to achieve greater support weight and more precise clamping accuracy, so that the chuck can drive small pipes to rotate at a higher speed and improve cutting High efficiency, no dead angle, zero tail cutting.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and more specifically relates to a laser tube cutting device. Background technique [0002] At present, laser pipe cutting devices can be divided into two-chuck pipe cutting devices, three-chuck pipe cutting devices, and four-chuck pipe cutting devices according to the number of chucks. There is at least one fixed chuck for fixed clamping and feeding of pipes. At least one rolling chuck centers and rotates the tube. [0003] The two-chuck pipe cutting device includes a fixed chuck and a rolling chuck. Its structure is relatively simple and easy to operate, but due to fewer clamping points, it is impossible to cut long and lower long materials; the three-chuck device consists of two It consists of a fixed chuck and a rolling chuck or a fixed chuck and two rolling chucks. It supports a large weight and cuts more accurately, but the length of the tube is slightly longer than that of the middl...

Problems solved by technology

[0003] The two-chuck pipe cutting device includes a fixed chuck and a rolling chuck. Its structure is relatively simple and easy to operate, but due to fewer clamping points, it is impossible to cut long and lower long materials; the three-chuck device consists of two It consists of a fixed chuck and a rolling chuck or a fixed chuck and two rolling chucks. It supports a large weight and cuts more accurately, but the length of the tube is slightly longer than that of the middle rolling chuck. When the thickness is too high, the graphics cannot be cut on the pipe, only the pipe can be cut, and when the length of the pipe is less than the sum of the thickness of the two rolling chucks, the section cannot be cut, and when the cutting head is offside to the end of the pipe for cutting, due to this It is necessary to loosen the fixed chuck at the tail, so it is impossible to cut the pattern of the tail of the pipe fitting, the waste of material is serious, and the automatic unloading cannot be realized when cutting offside

The four-chuck pipe cutting device generally includes two fixed chucks and two rolling chucks, which are two double-chuck structures mirrored, and its cutting head cannot achieve offside cutting, such as a four-chuck disclosed in Chinese patent CN111215760A. Chuck laser pipe cutting machine, although it can realize zero-tail cutting, can load and unload materials at the same time, and the cutting accuracy is more accurate, but this will result in a longer bed, and in fact only two chucks bear the load, the load is still small, and the occupation There is a lot of space, and it is necessary to control the rotation and feed of four chucks at the same time, and the control is more complicated
