Description
Technical field
The present invention relates to steel pipe recovery technique field more particularly to a kind of electromagnetism connector sleeve cold-drawn prosthetic device and reparation sides
Method.
Background technique
Steel pipe in use, can inevitably be deformed, be bent, so being frequently necessary to repair steel pipe, at present to steel
The method that pipe is repaired mainly has the technological means such as multiple roll aligning, mold correction, drawing reparation.And for longer steel pipe and
Speech, mostly use drawing reparation greatly, in the prior art, when due to cold-drawn need to one end part to steel pipe be fixed with clamp, this
Duan Gangguan size after cold-drawn will generate variation, and shape can also change, this section of material will be cut off as waste material, make
It is damaged at certain material；It is by welding one end steel pipe as cold-drawn collet, due to weldering in steel pipe one end there are also a kind of restorative procedure
Welded seam area mechanical properties of pipe significant changes will be will lead to by connecing heating, influence product quality；It is to adopt there are also a kind of restorative procedure
With pull rod, it is cased with steel pipe to be repaired on pull rod, steel pipe is pushed through into drawing mould by way of pushing away.
Such as prior art patent CN101602070A, disclose a kind of bearing calibration of outer diameter of steel pipes.This method be
In existing drawbench, increase the draw-off gear of a promotion steel pipe；The trolley pincers of drawbench draw draw-off gear, and draw-off gear pushes
Steel pipe is by drawing-die seat, to reach the correction of outer diameter of steel pipes.
Such as prior art patent CN106914518A, it discloses a kind of precision tube and exempts from collet cold-drawn prosthetic device and side
Method, it includes clamp cylinder, die holder and external mold, and one end of the pull rod is fixed on clamp cylinder, outside the other end of the pull rod
More steel pipes to be repaired are set with, are connected between the more steel pipes to be repaired by intermediate connecting sleeve support cooperation, in pull rod
The other end be fixedly installed with rear cover, the rear cover is by minor details steel pipe limit sleeve to be repaired on pull rod.
Such as prior art patent JPH09103819A, a kind of tube material drawing prosthetic device and restorative procedure are disclosed,
It is equally to be repaired bending tubing to be repaired push-in drawing mould using push-pull fashion.
Above-mentioned reparation tooling is when carrying out cold-drawn reparation, due to that will not cause changing for steel tube performance without making collet
Become, but steel pipe is pushed through into drawing mould by way of pushing away.This mode is easy so that the material of tubing is in push-in force side
Accumulation, influences the dimensional accuracy at the tubing end, and for steel pipe biggish for curvature, work of the crooked position in motive force
It is easy to happen corrugation under, and since curvature is straightened after being pushed into mold by bending, so that size obviously becomes larger, is pushing away
During entering or even it is difficult to be corrected reparation.
In the implementation of the present invention, inventor has found steel tube repairing device and restorative procedure in the prior art at least
It has the following deficiencies: for the drawing repair mode using the fixed pipe end of clamp, it need to be to steel pipe when due to cold-drawn
One end part is fixed with clamp, this section of steel pipe size after cold-drawn will generate variation, and shape can also change, this section
Material will be cut off as waste material, and certain material is caused to damage；For welding one section of steel pipe as cold-drawn collet in steel pipe one end
For, since weld heating will will lead to welded seam area mechanical properties of pipe significant changes, influence product quality；For using drawing
Bar is cased with steel pipe to be repaired on pull rod, for steel pipe is pushed through drawing mould by way of pushing away, is easy the material so that tubing
Material is accumulated in push-in force side, influences the dimensional accuracy at the tubing end, and for steel pipe biggish for curvature, bending section
Position is easy to happen corrugation under the action of motive force, and since curvature is straightened after being pushed into mold by bending, so that ruler
It is very little obviously to become larger, even it is difficult to be corrected reparation in push-on process.And the prior art is mostly both for round steel pipe
It repairs, is not involved with the prosthetic device and restorative procedure of square steel tube substantially.Based on this, inventor proposes one kind out of square steel tube
Portion's locking square steel tube, and drawing square steel tube simultaneously repairs the square steel tube of more large curved degree by drawing mould
It is multiple.
Summary of the invention
The present invention provides a kind of electromagnetism connector sleeve cold-drawn prosthetic device and restorative procedures, solve square steel in the prior art
Pipe prosthetic device and at least existing following technical problems of restorative procedure: for the drawing reparation using the fixed pipe end of clamp
For mode, when due to cold-drawn need to one end part to steel pipe be fixed with clamp, size will after cold-drawn for this section of steel pipe
Variation is generated, and shape can also change, this section of material will be cut off as waste material, and certain material is caused to damage；For in steel
For one section of steel pipe is welded as cold-drawn collet in pipe one end, shown since weld heating will will lead to welded seam area mechanical properties of pipe
Variation is write, product quality is influenced；For using pull rod, it is cased with steel pipe to be repaired on pull rod, is pushed away steel pipe by way of pushing away
Cross for drawing mould, be easy so that tubing material push-in force side accumulate, influence the dimensional accuracy at the tubing end, and
For steel pipe biggish for curvature, crooked position is easy to happen corrugation under the action of motive force, and due to curvature
It is straightened after being pushed into mold by bending, so that size obviously becomes larger, even is difficult to be corrected reparation in push-on process.Hair
Bright people propose it is a kind of from locking steel pipe inside square steel tube, and steel pipe drawing by drawing mould to simultaneously to more large curveds
