Embodiment Construction

[0018] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0019] A kind of processing method of herringbone intersecting line of metal pipe, such as figure 1 , figure 2 , image 3 and Figure 4 As shown, it includes the following steps:

[0020] Step 1. Provide the metal pipe 1 to be cut; determine the position where the metal pipe needs to be cut.

[0021] Step 2, make the pipe sleeve 2 according to the outer diameter of the metal pipe 1; the inner diameter of the pipe sleeve 2 is 1-2cm larger than the outer diameter of the metal pipe 1; the material of the pipe sleeve is metal; in order to improve the cutting quality, the pipe sleeve 2 is machined way made.

[0022] Step 3. Insert the sleeve 2 into the metal pipe and fix it on the metal pipe 1 where it needs to be cut; figure 1 As shown, the pipe sleeve 2 and the metal pipe 1 can be fixed by bolts 3 .

Abstract

The invention discloses a machining method for a V-shaped intersecting line of a metal pipe. The machining method comprises the following steps that the metal pipe needing to be cut is provided; a pipe casing is manufactured according to the outer diameter of the metal pipe; the inner diameter of the pipe casing is 1-2 cm larger than the outer diameter of the metal pipe; the metal pipe is sleeved with the pipe casing, and the pipe casing is fixed to the part, needing to be cut, of the metal pipe; a cutting device is used for simultaneously cutting the pipe casing and the part, located in the pipe casing, of the metal pipe to obtain the V-shaped intersecting line; the pipe casing is removed from the metal pipe. The machining method has the advantages of being good in cutting quality and high in cutting efficiency.

Description

technical field [0001] The invention relates to a processing method of a herringbone intersecting line of a metal pipe. Background technique [0002] During ship construction, it is often necessary to weld two metal pipes together. When the two metal pipes are not on the same straight line, the intersecting line of the two metal pipes needs to be cut first, and then the two metal pipes are welded at the intersecting line. Among them, the herringbone intersecting line is an intersecting line that often needs to be cut. At present, when cutting a herringbone intersecting line, usually a cutting device is used to directly cut the metal pipe. Cutting with this method, the section at the herringbone intersecting line of the metal pipe is rough, and there are many cutting defects, which need to be repaired and polished by hand after cutting, and the on-site cutting can only reach 12 pieces per day. Therefore, existing methods have the defects of poor cutting quality and low cut...
