Abstract
The utility model discloses a kind of seamless steel pipe tube expanders, utilize small jack and the flat mouth of pipe ring cooperation correction pipe end and necking, it is a kind of device for effectively correcting flat mouth and necking in steel pipe's production field more particularly to the biggish stainless steel tube production field of radius-thickness ratio that the tube expander, which is applied,.The tube expander uses small-sized jack, and pipe ring is put into pipe end and needs widened position by the pipe ring of an additional incision, by jack as on pipe ring, after jack reinforcing, pass through intermediate pipe ring, power is uniformly transmitted along each face of pipe ring as pipe, makes the pipe to be expanded along radially expanded.The production is simple and convenient for the tube expander, using flexible, easy to operate, low in cost, there is very high practical value.
Description
Technical field
The utility model relates to stainless-steel seamless pipe production field, specifically a kind of seamless steel pipe tube expander.
Background technique
In stainless steel tube production technology, aligning necking, flat mouth are generally existing in large-diameter and thin-wall pipe production.In pipe
In straightening process, aligning necking is inevitable, and each tube both ends all have the aligning necking that 100 ~ 300mm is not waited.It is flowing through
Because often occurring the flat mouth of pipe end during production flow weaker at pipe end in journey.This cutaway certainly will will cause waste, sternly
Ghost image rings lumber recovery.Especially scale pipe occur excision after above situation do not conform to position can short ruler, it may appear that whole branch waste product, seriously
Influence manufacturing schedule and cost.Currently with size specification in the market, equal jack can not in the pipe ring that cooperation is differed in size
To carry out pipe end correction to the biggish thin-wall tube of radius-thickness ratio, typical specification is 168.3*3.5,194*5,219*5 equal-specification.It is logical
Cross tube expander expander can outer diameter is small, deformation pipe end, be remedied to normal size, steel tube factory have biggish practical valence
Value.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of seamless steel pipe tube expander
Problem.
To achieve the above object, the utility model provides the following technical solutions:
A kind of seamless steel pipe tube expander, including pipe ring and jack, the pipe ring side cut with circumferential openings, pipe ring outside
It is arranged with rubber strip, pipe ring, rubber strip and jack are placed in inside pipeline.
As a further solution of the present invention: the pipe ring material is dual phase steel.
The dual phase steel model S31803 as a further solution of the present invention,.
It is somebody's turn to do compared with prior art, the utility model has the beneficial effects that steel tube factory's self-control may be implemented in the utility model
Tube expander corrects the unqualified position such as flat mouth, necking, restores qualified size, reduces Pipe Cutting loss, improves lumber recovery.
The tube expander is easy to make, flexible operation is simple, low in cost, there is very high practical value.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of seamless steel pipe tube expander；
Fig. 2 is a kind of left view of seamless steel pipe tube expander；
Fig. 3 is a kind of structural schematic diagram of pipe ring in seamless steel pipe tube expander；
A kind of structural schematic diagram when Fig. 4 is seamless steel pipe tube expander expander.
In figure: 1- pipe ring, 2- rubber strip, 3- jack.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Fig. 1-4, a kind of seamless steel pipe tube expander, including pipe ring 1 and jack 3 are please referred to, 1 side of pipe ring cuts with week
To opening, 1 outer sheath of pipe ring is equipped with rubber strip 2, and rubber strip 2 is made by electric vehicle rubber, and playing buffering prevents the work scratched
Determined with the selection of, jack 3 according to expander outer diameter, it is desirable to be able to be placed in institute's expander, then by pipe ring 1, rubber strip 2 with
Jack 3 is placed in the nozzle for needing expander, and the expansion of pipe ring 1 expands pipe after applying pressure, lets out after outer diameter diffuses into suitable dimension
Pressure, takes out tube expander, which is not limited by place, and not by time restriction, flexible operation is simple, low in cost.
1 material of pipe ring is dual phase steel, and the dual phase steel is using the materials such as S31803, high strength and deformation, when expander
Power is spread more easily along annulus, and pipe outside diameter is uniformly expanded.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in
All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting
Related claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
