Problems solved by technology

At present, the processing methods of intersecting lines mainly include manual cutting and CNC intersecting line cutting machine, etc. However, the manual cutting method is labor-intensive, and the welding seam of the intersecting line is poorly formed, and the overall appearance quality of the railing is low. The production efficiency is low and cannot keep up with the construction period and quality requirements of the existing projects; although the intersecting lines cut by the CNC intersecting line cutting machine have high precision, there are many procedures and cumbersome procedures. When there are many steel pipe parts to be processed, The cutting efficiency cannot meet the requirements

Embodiment 1

[0020] Embodiment 1: as Figure 1-4 A method for quickly processing intersecting lines of small-diameter steel pipes is shown, wherein the steel pipe 1 and the parent pipe 2 need to be processed orthogonally; this method includes the following steps:

[0021] 1), lofting, using computer lofting software to draw the intersecting line 6 of the steel pipe 1 and the parent pipe 2 to be processed, and calculate the highest point and the lowest point of the intersecting line 6, such as figure 1 shown;

[0022] 2), draw the cutting line, draw the corresponding highest point a, and the lowest point b, c on the steel pipe 1 to be processed (since the steel pipe 1 to be processed and the parent pipe 2 are orthogonal, the intersecting line between the two is on the plane The projection of is symmetrical to the center line of the steel pipe 2 to be processed, that is, there are two lowest points), connecting the highest point a and the lowest points b, c; the connection line ab and ac is...

Embodiment 2

[0027] Embodiment 2: as Figure 5 A method for rapidly processing intersecting lines of small-diameter steel pipes is shown, in which the steel pipe 8 and the mother pipe 9 need to be processed obliquely at an angle of 45 degrees. The steps included in this method are the same as those in Embodiment 1. In addition, since the steel pipe 8 and the mother pipe 9 need to be processed obliquely, the projection of the intersecting line 10 of the two on the plane is asymmetrical, such as Figure 5 and Figure 6 shown. Figure 6 The connection line fd and connection line fe in are the cutting line, and the section of the approximate intersecting line after cutting is as follows Figure 7 shown.

Abstract

The invention discloses a fast machining method of a minor-diameter steel pipe intersecting line. The machining method comprises the steps that laying-off is conducted, an intersecting line intersected with a mother pipe of a steel pipe need to be machined is drawn with the use of a computer laying-off software, and the highest point and the lowest point of the intersecting lie are calculated; a cutting line is drawn, corresponding highest point and lowest point are drawn in the steel pipe need to be machined, and the connecting line between the highest point and the lowest point is the cutting line; cutting is conducted, the cutting line is aligned through a saw machine grinding wheel blade, and the intersecting line is cut out; the diameter of the steel pipe need to be machined ranges from 20 mm to 60 mm. Compared with the prior art, the machining method of the minor-diameter steel pipe intersecting line has the advantages that for the minor-diameter steel pipe, the accuracy of the machined intersecting line is high, surface quality of a welding line at the position of the intersecting line is guaranteed, moreover, the operation procedure is few, the operation is simple, the saw machine can be used to cut the intersecting line directly, site-changing machining is not needed, the machining time is shortened greatly, the labor intensity is reduced, the working efficiency is improved greatly, and great popularization and application value is possessed on the machining filed of the minor-diameter steel pipe intersecting line.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a method for rapidly processing intersecting lines of small-diameter steel pipes. Background technique [0002] In steel structure factory buildings or venue buildings, there are often railings made of steel pipes with small diameters. Among them, there are many intersecting lines formed by two railings intersecting at right angles or at a certain angle, and the end faces formed by the intersection is a closed space surface. At present, the processing methods of intersecting lines mainly include manual cutting and CNC intersecting line cutting machine, etc. However, the manual cutting method is labor-intensive, and the welding seam of the intersecting line is poorly formed, and the overall appearance quality of the railing is low. The production efficiency is low and cannot keep up with the construction period and quality requirements of the existing projects; although ...
