Abstract
The present invention proposes a continuous steel pipe bending method, wherein a steel pipe bending production line is used to carry out unwinding, cutting butt-welding, spiral loop, molding, high-frequency heating, fixed diameter bending, and saw cutting. According to the present invention, the method has characteristics of continuous pipe bending, high production efficiency and easy adjustment; the processed product has characteristics of precise deformation radian, smooth surface, no pipe opening deformation, highly consistent size height of the pipes with the same batch, and interchangeability; and the method of the preset invention is suitable for the continuous steel pipe bending.
Description
Technical field
What the present invention proposed is the method for the continuous bending of a kind of steel pipe of field of machining.
Background technology
The Apparatus and method for that can realize bend pipe at production line steel pipe traveling process is not had to be used in prior art.Therefore continuous bend pipe can not be realized.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the present invention proposes a kind of continuous bending method of steel pipe.The method utilizes uncoiler, Shearing Butt Resistance Welder, spiral loop, forming machine, High Frequency Solid State, sizing bending machine, sawing machine with the use of.Solve the technical problem of the continuous bending of steel pipe.
The scheme that technical solution problem of the present invention adopts is:
With steel pipe bending production line, carry out uncoiling, shear butt welding, the bending and sawing process of spiral loop, shaping, high-frequency heating, sizing.
Described uncoiling adopts uncoiler to be opened by steel band, forms continuous print tabular steel band;
Described shearing butt welding adopts Shearing Butt Resistance Welder by curling for steel band butt welding, becomes tubulose;
Described spiral loop spiral loop mechanism is by steel pipe rotary;
Described shaping employing forming machine carries out shaping with sizing to the steel pipe welded;
Described High Frequency Solid State heating heats up with heating generator Welded Pipe, reduces rigidity, make it to possess plasticity, be conducive to tube bending;
Described sizing is bending adopts sizing bending machine, by the adjustment of bending roll angle, requires to carry out bending by intended diameter according to flexibility;
Described sawing sawing machine cuts off bend loss, forms the bend steel tube of preseting length.
Good effect, the present invention can bend pipe continuously, have production efficiency high, be easy to the advantage that adjusts.The deformation of products radian processed is accurate, smooth surface, and the mouth of pipe is without distortion, consistent with batch pipe dimensional height, has interchangeability.The method application of suitable steel pipe continuous bend.

Detailed description of the invention
According to the figure, with steel pipe bending production line, carry out uncoiling, shear butt welding, spiral loop, shaping, high-frequency heating, sizing is bending and cut process.
Described uncoiling, adopts uncoiler 1 to be opened by steel band, forms continuous print tabular steel band;
Described shearing, butt welding adopts Shearing Butt Resistance Welder 2 by curling for steel band butt welding, becomes tubulose;
Described spiral loop, with spiral loop 3 mechanism by steel pipe rotary;
Described shaping, adopt forming machine 4 to carry out the steel pipe welded shaping with sizing;
Described High Frequency Solid State, utilizing High Frequency Solid State 5 to heat is heat up with heating generator Welded Pipe, reduces rigidity, makes it to possess plasticity, be conducive to tube bending;
Described sizing bends, and adopts sizing bending machine 6, by the adjustment of bending roll angle, requires to carry out bending by intended diameter according to flexibility;
Described sawing, cuts off with sawing machine 7 pairs of bend loss, forms the bend steel tube of preseting length.
Utilize existing ERW welded pipe units to increase a set of pipe bending mechanism at sizing place and complete steel pipe bending deformation process.
Bend pipe process is undertaken by pipe bending mechanism, described pipe bending mechanism is the adjustment by the pair roller depth of parallelism, realizes the flexural deformation of different-diameter steel pipe, is heated by high frequency in bend pipe process to the steel pipe before bend pipe, make it to possess pliability, be conducive to the bending of steel pipe.
Owing to adopting, the inventive method has continuously, production efficiency is high, and the feature that dimensional accuracy is high, product can be used for roof structure or other arc-shaped steel shelf structures of large span, is better than grid structure.
