Abstract
The invention discloses a kind of bending methods of bend pipe.The bending method of a kind of bend pipe disclosed by the invention comprising following steps: (1) straight tube is cut with sawing machine for cutting；Straight tube is polished after cutting；(2) assembly flange and casing on school pipe platform；(3) flange and straight tube carry out human weld；(4) bend pipe is carried out using Pipe Bending Machine with Non-core.A kind of bending method of bend pipe provided by the invention assembles simple, more efficient；It is convenient welding, high-efficient, high-quality.
Description
Technical field
The present invention relates to a kind of bending methods of bend pipe.
Background technique
Bend pipe bending method be pipe is curved good, assembly flange and casing are welded again.First welded after the pipe of school, bend pipe
The welding quality that welding quality is not so good as straight tube always is good.Straight tube can weld on turning rolls, and welding position controls well, weld hand
Gesture is relatively fixed；And bend pipe can not be placed on rotating welding on turning rolls, can only manually gesture, multiposition weld.Due to bend pipe
Overturning is difficult, and the position welded is more, therefore welding quality and welding efficiency are all relatively low.
Summary of the invention
The technical problem to be solved by the present invention is in order to overcome in the prior art pipe it is curved good, assembly flange and casing are again
The defect welded and cause welding quality and welding efficiency all relatively low, and a kind of bending method of bend pipe is provided.
The present invention solves above-mentioned technical problem by the following technical programs.
The present invention provides a kind of bending method of bend pipe comprising following steps:
(1) straight tube is cut with sawing machine for cutting；Straight tube is polished after cutting
(2) assembly flange and casing on school pipe platform；
(3) flange and straight tube carry out human weld；
(4) bend pipe is carried out using Pipe Bending Machine with Non-core.
In a preferred embodiment of the present invention, in step (1), the caliber of the straight tube is 22~89 millimeters.
Without prejudice to the field on the basis of common sense, above-mentioned each optimum condition, can any combination to get the present invention it is each preferably
Example.
The positive effect of the present invention is that: assembly is simple, more efficient；It is convenient welding, high-efficient, high-quality.
Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.In the following examples, the experimental methods for specific conditions are not specified, according to conventional methods and conditions, or according to quotient
The selection of product specification.
Embodiment 1
Will be 12 meters long, the straight tube that 22 millimeters of caliber is cut in cutting area with sawing machine for cutting, and the straight tube of well cutting is placed
In polishing moulding bed on polish, in the straight tube handling polished to school pipe platform carry out assembly flange, casing, then handling to weld
It connects and completes human weld on moulding bed.The pipe being welded successively is used Pipe Bending Machine with Non-core to carry out bend pipe by drawing.
Embodiment 2
Will be 8 meters long, the straight tube that 89 millimeters of caliber is cut in cutting area with sawing machine for cutting, and the straight tube of well cutting is placed in
Polishing moulding bed on polish, in the straight tube handling polished to school pipe platform carry out assembly flange, casing, then handling to weld
Human weld is completed on moulding bed.The pipe being welded successively is used Pipe Bending Machine with Non-core to carry out bend pipe by drawing.
Comparative example 1
Will be 12 meters long, the straight tube that 22 millimeters of caliber is cut in cutting area with sawing machine for cutting, and the straight tube of well cutting is placed
It polishes on polishing moulding bed, the straight tube polished successively is used Pipe Bending Machine with Non-core to carry out bend pipe processing by drawing, is handled well
Bend pipe handling to school pipe platform on carry out assembly flange, complete human weld on casing, then handling to welding positioner.
Effect example 1
Entire process is carried out to embodiment 1,2 and comparative example 1 and carries out time-consuming calculating, and welding quality is beaten
Point evaluation (by ten point system give a mark, score is higher, indicate more close to best features), the results are shown in Table 1.
Table 1
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, many changes and modifications may be made, but these change and
Modification each falls within protection scope of the present invention.
