Development along with traction electric machine, be applied to the electromagnetic wire product on the High power Traction motor, as its important parts, its mechanical property and electric property are extremely important, and as copper cash and the aluminum steel of conductor, the electric property after its bending property and the bending is then particularly important.
Present crooked test instrument can't detect the bending property on metal B limit (narrow limit).All there are the problem that distorts in a roll-type or the vice type described in ASTM E290-97 and GB4909.6-2009 standard in actual application, and domestic only have be applicable to detect the B limit less than or equal to the Apparatus for Bending at low-temp of 16mm, for the bent tester of larger-size metal B spring, at present domestic temporarily do not have.Therefore need to improve further prior art.
The utility model content
Problem to be solved in the utility model is: can't detect the bending property on metal B limit (narrow limit) for bend testing apparatus in the prior art, the utility model provides a kind of size that can solve greater than the copper bar of 0.8mm and the device of flat aluminium wire metal B spring Qu Xingneng.
In order to address the above problem, solution of the present utility model is: a kind of bend testing apparatus comprises cake, depression bar, pad, pressure roller, a roller, tested exemplar, bearing and fin.It is characterized in that, above-mentioned bearing has two, and the correspondence position two bearing baffle plate inboards has two roller holes and pressure roller grooves, and two roller holes are positioned on the same level, and the pressure roller groove is positioned at two roller hole midline, and groove prolongs vertical.
Further, a roller hole is used for placing a roller, puts into pressure roller in the pressure roller groove, and pressure roller can move along the direction of groove, so that corresponding press-bending power to be provided.The bearing bottom is provided with fin, plays certain strengthening action for the intensity of bearing.And the length of roller or pressure roller is all greater than the width of test specimen, and has enough rigidity and smooth finish.
Further, coupled together by two rollers and a pressure roller between two bearing baffle plates.And the end of a roller has been attacked screw thread, so that and the spacing between two bearings of adjusting.
Further, have one group of pad to be used for the location on a roller and the pressure roller, can prevent that testee from producing slippage and torsional deformation, axle and pad can be matched different diameters according to test request.
Further, cake and depression bar have consisted of press member, and the depression bar bottom is the circular arc of indent, and arc radius is identical with the pressure roller radius, can remain that like this force application element and tested exemplar are the vertical motion.
Further, this device is connected use with universal testing machine, and pressure and speed all can be regulated, and flexible 0～180 °, observes crooked rear surface cracking situation.
The utility model has the advantage of: this device and universal testing machine are used in combination, circular arc pressure head with indent, can guarantee that pressure head and sample are in metastable position in the bending test process, the tested position of sample is realized accurately the location and can not be produced slippage and torsional deformation.This apparatus structure is compact, easy operating, uses simple and flexible, safe ready, and flexible 0～180 °, can observe comparatively intuitively crooked rear surface cracking situation, have practical value.

Among the figure: 1-cake, 2-depression bar, 3-pad, 4-pressure roller 5-roller 6-tested exemplar 7-bearing 8-fin
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As depicted in figs. 1 and 2, a kind of bend testing apparatus comprises cake 1, depression bar 2, pad 3, pressure roller 4, a roller 5, tested exemplar 6, bearing 7 and fin 8.It is characterized in that, above-mentioned bearing 7 has two, and the correspondence position two bearing 7 baffle plate inboards has two roller holes and pressure roller grooves, and two roller holes are positioned on the same level, and the pressure roller groove is positioned at two roller hole midline, and groove prolongs vertical.
As further embodiment of the present utility model, a roller hole is used for placing a roller 5, puts into pressure roller 4 in the pressure roller groove, and pressure roller 4 can move along the direction of groove, so that corresponding press-bending power to be provided.Bearing 7 bottoms are provided with fin 8, play certain strengthening action for the intensity of bearing.And the length of roller 5 or pressure roller 4 is all greater than the width of tested exemplar 6, and has enough rigidity and smooth finish.
As further embodiment of the present utility model, coupled together by two rollers 5 and a pressure roller 4 between two bearing baffle plates.And the end of a roller 5 is processed with screw thread, so that regulate two spacings between the bearing.
