Abstract
The invention relates to a laser cutting method of a square pipe, and relates to the technical field of laser cutting. The square pipe comprises a plane and a corner. The method includes the following steps of cutting the plane of the square pipe through a cutting head according to a preset track, wherein the relative speed of the cutting head and the square pipe in the cutting direction is V1; rotating the square pipe so that the cutting head can move accordingly, wherein the relative speed of the cutting head and the square pipe in the cutting direction is V2, and V2 is smaller than V1; connecting the cutting head with a gas storage cylinder storing compressed gas, and blowing away slag produced in the cutting process through the gas, wherein the gas pressure in the gas storage cylinder is kept between 1.0 Mp to 2.0 Mp and not smaller than 0.8 Mp. By means of the cutting method, the cutting quality can be improved.
Description
Technical field
The present invention relates to laser cutting technique field, especially relate to a kind of laser cutting method of rectangular tube.
Background technology
At present, desk adopts steel pipe support and desktop composition usually, but all there is difference due to the size dimension of desk, steel pipe support adopts fixture to carry out combination and fixes, therefore, on steel pipe support, need to offer the circular port of different size or square hole or profiled holes, adopt common processing method to be difficult to above-mentioned processing.In addition, current domestic laser cutting machine in the cutting of dull and stereotyped and pipe material, be obtained for good application, but there is no good solution and way in the cutting of the square metal tubing adopted at desk, cutting technique is immature, the cut quality of square pipe cannot be improved, the requirement of product cannot be met.
Summary of the invention
The invention provides a kind of laser cutting method of rectangular tube, can cut quality be improved.
Technical problem solved by the invention realizes by the following technical solutions:
A laser cutting method for rectangular tube, described rectangular tube comprises plane and corner two parts, comprises the following steps:
101, cutting head cuts by the planar section of desired trajectory square shaped pipe, and cutting head and rectangular tube relative velocity is in the cutting direction V1;
102, rotate described rectangular tube, cutting head follows movement, and cutting head and rectangular tube relative velocity is in the cutting direction V2, and V2 is less than V1.
Wherein, described cutting head is connected with the air accumulator containing Compressed Gas, and the air pressure in described air accumulator remains on 1.0Mp-2.0Mp, lower than 0.8Mp, must not be blown away the slag of cutting process generation by gas.
In step 102, cutting head is followed the rotation of rectangular tube and moves, and the laser beam that cutting head is sent is through the center of circle of described corner place circle.
In step 102, when plane is transitioned into the cutting of corner, rotate described rectangular tube.
In step 102, determined the rotational angle of described rectangular tube by segmentation crank degree.
In step 102, initial in 45 degree at corner, the velocity of rotation of rectangular tube such as is at the accelerator, and corner 45 degree in 90 degree, the velocity of rotation of rectangular tube such as is at the moderating process.
Described rectangular tube is carbon steel or stainless steel material.
The invention has the beneficial effects as follows:
Adopt different cutting speeds for cutting plane and the corner of rectangular tube in the present invention respectively, and cutting corner hourly velocity diminish, and is conducive to fully effectively cutting corner; When cutting corner, laser beam is perpendicular to the plane of cutting, namely laser beam is through the center of circle of corner place circle, initial in 45 degree at corner, the velocity of rotation of rectangular tube such as is at the accelerator, and corner 45 degree in 90 degree, the velocity of rotation of rectangular tube such as is at the moderating process, concrete shape so just for tubing is changed cutting method adaptively, improves the cut quality that tubing is final.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
With reference to shown in Fig. 1-2, the laser cutting method of rectangular tube of the present invention, described rectangular tube comprises plane and corner two parts, comprises the following steps:
101, cutting head cuts by the planar section of desired trajectory square shaped pipe, and cutting head and rectangular tube relative velocity is in the cutting direction V1;
102, rotate described rectangular tube, cutting head follows movement, and cutting head and rectangular tube relative velocity is in the cutting direction V2, and V2 is less than V1.
Wherein, described cutting head is connected with the air accumulator containing Compressed Gas, and the air pressure in described air accumulator remains on 1.0Mp-2.0Mp, lower than 0.8Mp, must not be blown away the slag of cutting process generation by gas.
In step 102, cutting head is followed the rotation of rectangular tube and moves, and the laser beam that cutting head is sent is through the center of circle of described corner place circle.
In step 102, when plane is transitioned into the cutting of corner, rotate described rectangular tube.
In step 102, determined the rotational angle of described rectangular tube by segmentation crank degree.
In step 102, initial in 45 degree at corner, the velocity of rotation of rectangular tube such as is at the accelerator, and corner 45 degree in 90 degree, the velocity of rotation of rectangular tube such as is at the moderating process
Rectangular tube is carbon steel or stainless steel material.
Below method of the present invention is specifically described:
Use normal dull and stereotyped cutting mode in square tube plane cutting, on the corner want low speed cutting; When square tube is rotated, cutting head the cutting cutting edge of moment and square tube must keep a certain relative velocity, and the relative velocity of whole process is all different, and the control therefore for programming coordinates position is of crucial importance.The equipment needed has: the laser cutting machine of joining rotary table, and requires that rotary table fixture is chuck.
