Description
Technical field
It the utility model is related to the tube straightening device used in a kind of steel tube flaw detection detection device；More particularly to one kind
Steel pipe smoothing roll installation and adjustment structure.
Background technology
Steel pipe is a kind of wide variety of important ferrous materials, because various factors influences during steel pipe's production,
The defects of longitudinal crack, transversal crack, folding, layering are commonly present in steel pipe walls.Will be among use if steel pipe is defective
Rupture causes accident, or even causes serious consequence, may cause heavy economic losses even casualties, be this important use
Steel pipe is required for perfect non-destructive detecting device, and line flaw detection is carried out to steel pipe.To ensure the quality of steel pipe of dispatching from the factory, existing spy
Hindering mode mainly has ultrasonic examination and the eddy current inspection method of inspection.Existing steel tube flaw detection line, often by ultrasonic inspection and whirlpool
Stream flaw detection is used as single runtime, but with the raising of present Tube heating furnace requirement, often needs to complete it two kinds of detections,
At this moment operating personnel are just needed by the steel pipe blanking after the completion of passing through a kind of flaw detection, then are transferred to lower road carrying out flaw detection, work be present
Repeat, labor intensity it is big, examine cycle of operation length, it is inefficient the shortcomings that, turn into and restrict one of steel tube flaw detection detection speed
Factor.
In existing steel tube flaw detection equipment, either import equipment or home equipment, natural pipe through roll forming it
Afterwards, flaw detection link can just be entered.Because rolled steel tube surface is inevitably improper in the presence of transporting, placing, and itself stress
Secular distortion, or external factor influence etc., these factors can cause to deform again before steel tube flaw detection, such as locate not in time
Reason, the steel pipe of deformation can be because of linearitys or surface quality is bad is had an impact for flaw detection effect, it is impossible to ensure the stabilization of flaw detection
Property.If clearing up not in time, flaw detection can be made a big impact, serious interference be produced during flaw detection, or even mistake can be produced
The situation that report is even failed to report.
Meanwhile ultrasonic automatic flaw detection apparatus, particularly the flaw detection industry neck in the steel pipe part using ultrasound detection
Domain has a wide range of applications, such as automatic flaw detection device for steel pipe part etc..The existing online ultrasonic inspection of steel pipe, typically
Line flaw detection is carried out using the method for probe moisture film coupling.When free of Automatic Ultrasonic Flaw Detector is carried out to steel pipe, it will usually visit
At a certain distance from head is attached to outer surface of steel tube with certain mechanical mechanism, probe is made by the regulating system adjusted on probe holder
Certain gap is left between steel pipe, and water-filling forms coupling moisture film, is detected a flaw by ultrasound emission.In actual automatic spy
During wound, because steel pipe is in the transmission process of detection, the probe of existing ultrasonic automatic flaw detection apparatus is typically direct
It is fixed on probe bracket, and probe bracket is fixedly connected with flaw detection water tank, because steel pipe model is more, probe fixation is set
Put, the flaw detection demand of various different model steel pipes can not be met.Simultaneously during steel tube flaw detection, run into the position of the default in the steel pipe and pass through
When, easily and probe touching causes the vibration of probe and stuck up to turn, so as to cause the change of flaw indication amplitude, if can not be timely
Regulation, it can also influence the reliability and accuracy of flaw detection.For eddy current inspection there is also it is identical the problem of.
In order to solve the above problems, applicant considers to set steel pipe feed straightening device in steel pipe defectoscope feed end,
Steel pipe feed straightening device includes an aligning case, and aligning case includes vertically arranged positioned at steel pipe motion path left and right directions
Two blocks of side plates and the two end plates positioned at steel pipe motion path direction, two blocks of side plates and two end plates surround rectangular frame and fixation
On bottom plate, in addition to the smoothing roll being arranged in pairs, each pair smoothing roll are separately positioned on two pieces of side plate interior sides faces, smoothing roll week
To the arc that surface is middle part indent, two smoothing rolls are arranged in the left and right directions two of steel pipe motion path in each pair smoothing roll
Side, its feature are that the axial line of two smoothing rolls misplaces up and down along the steel pipe direction of motion to be obliquely installed so that two smoothing rolls
Each and steel tube surface forms two symmetrical spiral linear contact lays.
So, feed and detect a flaw again after first being aligned to steel pipe, can preferably avoid, steel pipe is led because of self-deformation
Cause linearity or surface quality bad for being influenceed caused by flaw detection effect, improve the accuracy and reliability of flaw detection.Wherein steel
Form two symmetrical spiral linear contact lays with smoothing roll during pipe advances and realize aligning, therefore only need a pair of smoothing rolls to can be achieved
Aligning on the segment length direction of steel pipe one, and stress balance, simple in construction and leveling effect are good.
But in the steel pipe feed straightening device, it is also necessary to the installation and regulation for facilitating smoothing roll are further given consideration to how, with
The problem of adapting to different steel pipe models, and improving leveling effect, can preferably improve follow-up flaw detection effect.
