Description
Technical field
The present invention relates to a kind of locating device of rectangular steel tube detection field, particularly, relate to a kind of square tube flattening test positioning device.
Background technology
Along with the development of auto industry fast and stable, the passenger vehicle industry is also in fast continual development.Different from the pipe of common kart skeleton, Bus Frame is mainly the secondary processing of all types of pipes, and wherein rectangular tube obtains widely applying in Bus Frame.Safe, energy-conservation, light-weighted trend is more and more obvious in recent years, and various new materials begin to be widely used in automobile and comprise in the bus industry, and wherein the use of advanced high-strength steel is particularly outstanding.Compare with plain carbon steel, high-strength steel material intensity obviously improves, and is satisfying under the prerequisite of country to passenger vehicle rollover and safety requirements like this, can reduce the thickness of the rectangular tube that uses in skeleton and the vehicle frame, has also realized the lightweight of passenger vehicle simultaneously.
But the present domestic high-strength steel rectangular tube production line that there is no specialty, existing equipment all is for the production of former Medium And Low Strength Steels square tube, because the difference of material property, directly applies on the high-strength steel and a lot of quality problems can occur, such as cracking etc.So in order to produce up-to-standard product, need to be optimized improvement to existing device parameter and forming mode etc.And in research process, need repeatedly the high-strength steel square tube of producing to be carried out quality testing, wherein a detection method is exactly that square tube is flattened experiment.
According to the elaboration among the GB/T246-2007, in order to measure the plastic deformation ability of circular cross section metal tube, metal tube can be flattened to observe the defectives such as whether it ftractures.For square tube, there is no the GB regulation, also adopt at present similar approach, square tube is flattened along the diagonal of xsect, observe it and crackle whether occurs.
In the prior art, generally only manually that square tube one end folder is flat to a certain degree with large clamp, see that whether it ftractures, and does not need other relevant devices.Although this method is convenient and swift, there are many drawbacks.At first, manual flattening relatively is difficult to realize when the square tube size is larger, is only suitable in the small size square tube.In addition, manually flattening is to crimp onto by rule of thumb to a certain degree fully, can not more accurate realization crimp onto a certain degree.And because the method only operates at pipe end, the reliability of measurement result still remains to be discussed.
For fear of above-mentioned drawback, can use for reference the method for pipe flattening test, place press to flatten square tube.But different from pipe, owing to be that square tube is flattened along the diagonal of xsect, so square tube tiltedly must be put, so just must manage to solve the orientation problem of square tube.
Find through the retrieval to the prior art document, the utility model patent of Chinese patent application numbers 200720039917.8 discloses a kind of metal pipe flatening mill, this metal pipe flatening mill comprises: frame, fuel tank is set in the frame, be provided with oil pump in the fuel tank, oil pump is connected with motor on being arranged on fuel tank by shaft joint, on frame, be provided with oil cylinder, described frame is arranged with two oil cylinders in parallel, oil cylinder is connected with cope match-plate pattern respectively by piston rod, the below of cope match-plate pattern is provided with lower bolster, and the oil-out of oil pump communicates with the oil-in of two oil cylinders respectively by pipeline.This apparatus structure is comparatively complicated, and is mainly used in the extruding at metal pipe material two ends, and is not to be that tubing is laterally flattened.
Chinese patent application number: 200920190972.6, proprietary term: stainless steel welded pipe flattening test positioning device.This patent readme is: include support, centering slide calliper rule and scale, described scale is for vertically being fixed on the pedestal, and on scale, vertically be distributed with scale value, described centering slide calliper rule can slide up and down and are arranged on the scale, and are provided with the detent mechanism that can make the centering slide calliper rule be positioned the arbitrary position of scale between scale and centering slide calliper rule.But for square tube, this device can't be fixed in square tube on the press bed, thereby can not carry out flattening test.
In sum, there are because not having to satisfy the locating device of rectangular steel tube flattening test so that the square tube flattening test can't use press to carry out the technical matterss such as operating difficulties, the precision that can't overcome manual flattening existence is low, poor reliability in the prior art.Therefore, provide a kind of adaptation market development demand, the locating device that can satisfy the square tube flattening test is extremely urgent.
