Abstract

The invention relates to the assembly of pipes for gluing or welding at an angle to each other. The purpose of the invention is to simplify the assembly process. The method differs from the known ones in that after cutting the pipe into blanks at an angle of cutting a, the blanks are moved apart in the axial direction to a distance of 1 D tg (90 ° C) -1p, where D is the outer diameter of the pipe; B is the width of the cut. Then, one of the blanks is rotated around its axis by an angle of 180 °, and then one of the blanks — around the axis — is yush, it is the line of intersection of the surfaces formed during the cutting process, by an angle of 180 °. 4 il. with SS

The invention relates to the assembly of pipes for gluing or welding at an angle to one another.

The purpose of the invention is to simplify the process; i; a assembly.

FIG. 1--4 shows the method of assembling Grub at an angle operationally.

The process of assembling pipes at an angle is carried out in the following sequence.

The pipe is cut into blanks at a given angle a, (Fig. 1}, and one part of the pipe is removed (Fig. 2) in axial direction by distance

 Dtg {90 ° -a). P, where D is the outer diameter of the pipe;

1p - cutting width;

and - cutting angle.

Then, it is rotated around its axis by 180 ° and the movable part of the pipe is rotated around the axis, which is the intersection of the surfaces, which are formed during the cutting process, through an angle of 180 ° cc.

The proposed method for assembling pipes under the ANGLE can be recommended for soldering, gluing, and flange operations.

Example. The pipe assembly at an angle is slid in the following sequence. The pipe is trimmed under a given glom (1). The cutting is done with a 1.5 mm thick disc cutter. Pull back

The movable part of the pipe (II) in the axial direction of the pipe from the stationary part to the distance 1, which is determined from the ratio l) tg (90 ° -a) -IP, where D is 400 mm, a is 45 °, b, 5 mm therefore 1 398.5 mm. Rotate the movable part of the pipe by 180 ° (III) and rotate the movable part of the pipe around the axis, which is the line of intersection of the surfaces formed during the cutting process at an angle of 135 ° (IV).
