Description
Technical field
The present invention relates to a kind of hot-expanding steel tube Non-Destructive Testing aut.eq., relate in particular to a kind of automatic nondestructive testing device of oversized diameter seamless hot-expanding tube.
Background technology
In modern industry was produced, hot-expanding steel tube was one of large diameter thin wall production technology of steel tube, and its characteristics are that operation is simple, mould manufacturing and with short production cycle, and production cost is low.Thereby at present many middle-size and small-size producers adopt heat to expand technology and produce steel pipe, have shortened the Development and Production cycle of new product greatly, instant effect, the suitable needs that put goods on the market fast.In the hot-expanding steel tube manufacturing process, the Non-Destructive Testing before all hot-expanding steel tubes all need to dispatch from the factory so that find substandard product, is eliminated accident potential among bud.Because the hot-expanding steel tube diameter is generally bigger, often reaches 500～1200mm, existing nondestructive examination checkout equipment is all less, can't satisfy the quality testing of super-large diameter hot-expanding pipe.
Summary of the invention
The purpose of this invention is to provide a kind of super-large diameter hot-expanding steel tube Non-Destructive Testing aut.eq., and has a steel pipe rotation gear train that advances, ultrasound wave, eddy-current crack detector, thus solve the technical deficiency of existing equipment and a kind of novel super-large diameter automatic flaw detection of steel pipes mode is provided.
The objective of the invention is to be achieved through the following technical solutions.
A kind of super-large diameter hot-expanding steel tube Non-Destructive Testing aut.eq., comprise transmission shaft, eddy current probe, flaw detection main frame, roller-way unit, gearing, water tank, ultrasonic probe and main engine bed, the roller-way unit is connected by transmission shaft, and gearing is connected the unit rotation of the whole roller-way of drive with transmission shaft; Flaw detection main frame both sides roller-way is respectively material loading and blanking device, in the middle of main frame is positioned at and on main engine bed; The main body that water tank occupies the flaw detection main frame is lifted by eight springs; Ultrasonic probe is installed in the probe grooves of below of water tank, and eddy current probe is fixed and stretched out main frame directly over charging roller and be provided with screw rod and can adjust its height.
Described roller-way unit makes its rotation by the drive of gearing and transmission shaft, by the certain angle of roller steel pipe is advanced, and steel pipe just can rotate and advance like this, and the angle that can change rotating speed of motor and roller changes rotation and pace; Ultrasonic probe can be avoided hindering main frame with the hard clashing and breaking of steel pipe by spring lifting with water tank, and two groups of ultrasonic probes are installed on before and after the bottom of water tank two side positions and immerse in the water, and the angle of probe can freely be adjusted.
Automatic nondestructive testing device of oversized diameter seamless hot-expanding tube of the present invention, one group of eddy current probe, earlier steel pipe is carried out eddy current test, two groups of ultrasonic probes are installed on front and back, bottom two side positions of water tank, immerse in the water and again steel pipe is carried out UT (Ultrasonic Testing), thereby the angle of ultrasonic probe can be found out the detection of correct incident angle realization to vertical, the interior and external defects of steel pipe according to the steel pipe adjustment of different size by the method for water logging flaw detection; Therefore the specification limit that detects steel pipe is bigger, detectable external diameter φ 508～φ 1200mm, the steel pipe of wall thickness 8～60mm; Form by 16 channel defects detecting systems, adopt the steel pipe rotation to advance, by the eddy-current crack detector before the main frame outside surface of steel pipe is detected a flaw, the detection mode of the motionless water logging coupling of ultrasonic probe is vertical to weldless steel tube, defect in inner surface detects, and two kinds of flaw detection modes are once finished.
Beneficial effect of the present invention is:
(1) method of detection of the present invention adopts the water logging coupling process to survey seamless large-diameter pipes, and probe can be adjusted the comprehensive detection of incident angle realization to steel tube defect; The steel pipe scope of surveying is wide, has an enormous advantage than the moisture film flaw detection, and the necessary effective a kind of probe of a kind of gauge steel of moisture film probe, and the water logging coverage is big, does not need a kind of probe of a kind of specification.
(2) super-large diameter hot-expanding steel tube Non-Destructive Testing automatic flaw detection device of the present invention is reliable and stable, and repeatability is fine, when moisture film method moisture film forms, have air to enter the influence flaw detection and produce wrong report, and this device probe is all under water, is difficult for producing the wrong report phenomenon.
