Abstract
The invention relates to the field of mechanical equipment and particularly relates to an overturning plate type bending device. The overturning plate type bending device comprises a pressure head and a bending worktable which are connected with a testing machine, and is characterized in that the bending worktable is connected with two bent supports by bolts; a U-shaped groove is formed in the upper part of each bent support and a through hole is formed in the bottom of each bent support; each U-shaped groove is internally provided with an overturning plate; each overturning plate is connected with two edges of the corresponding U-shaped groove by trunnions; the overturning plates are connected with the trunnions by flat keys; and the pressure head comprises a compression roller support and a compression roller which are connected by a bolt. According to the overturning plate type bending device, the distance between the two bent supports is adjusted and the bent pressure head is replaced so that common bending test requirements can be met and a 180-degree bending test also can be carried out; and the overturning plate type bending device can be applied to a hydraulic universal testing machine, a hydraulic pressure universal testing machine and an electronic universal testing machine, and can be easily detached after two supporting points are bent to the equal heights and a test is finished.
Description
Technical field
The present invention relates to mechanized equipment field, be specifically related to turnover panel bending apparatus.
Background technology
Bending test on bending apparatus, stands bending ductility distortion with circular, square, rectangle or polygonal crosssection sample, do not change afterburning direction, until reach the test angle of regulation.During bending test, the axis of sample two-arm remains in the plane perpendicular to bending axis.As the bending test for 180 ° of angles, according to the requirement of products standards, sample being bent to two-arm at a distance of predetermined distance is parallel to each other or two-arm directly contacts.
Bending test is mainly used to the mechanical property of experimental material when standing bend loading effect, and in production application, conventional bending test evaluates the ability that material bears bending ductility distortion, is the important references index of quality control and application design.At present, the bending apparatus great majority that Material Testing Machine uses are a roller type bending apparatus, and this bending apparatus, due to the restriction by structure, does not reach the requirement of 180 ° of angular distortion tests, there is no angle deixis, cannot eliminating the not contour problem because manufacturing the two bending fulcrums brought yet.
Summary of the invention
In order to solve the problem, the invention provides one and there is 180 ° of angular distortion test functions, angle deixis, and solve the not contour problem of bending two fulcrums and tested the slat crooked device that rear difficulty pulls down sample problem.
Slat crooked device of the present invention, comprise the pressure head and bending table that are connected with testing machine, described bending table has been bolted two Bending supports, described Bending support top has U-shaped groove, bottom has through hole, a turnover panel is provided with in U-shaped groove, described turnover panel is connected by the both sides of gudgeon with U-shaped groove, turnover panel is connected by flat key with gudgeon, two Bending supports are connected by a pull bar, the axis of described pull bar and the axes coincide of Bending support through hole, and connecting rod two ends are all socketed with knurled nut, described pressure head is arranged between two Bending supports, and can move up and down to apply acting force, pressure head comprises the pressure roller bearing and pressure roller that are connected by screw.
Preferably, two Bending supports are respectively arranged with a circular scale, are positioned on the axis of gudgeon at circular scale central point, gudgeon is fixedly connected with a back-up ring and pointer.
Preferably, two Bending supports are respectively arranged with the wedge block of a band certain angle.
Preferably, bending table is provided with a scale.
The present invention changes bending pressure head by the Distance geometry between adjustment two Bending support, can meet the testing requirements of different size gauge coupons.Slat crooked device can meet common bending test requirement, also can do the test of 180 ° of angular distortions, can be applicable to universal hydraulic testing machine, hydraulic pressure testing machine and electronic universal tester, and bending two fulcrums contour, tested rear readily removable under.
