Abstract
The utility model relates to a testing device for bending around an axis. The testing device comprises a bottom plate, wherein a bending testing device is arranged on the bottom plate; the bending testing device comprises two supporting plates, a testing component clamping device arranged between the lower parts of the two supporting plates, an U-shaped frame arranged between the upper parts of the two supporting plates, a guide wheel, a bent mandrel, a reinforcing rod and bending angle indicating instruments, wherein the guiding wheel and the bent mandrel are arranged at the middle of an opening of the U-shaped frame; the reinforcing rod is arranged outside the U-shaped frame; and the bending angle indicating instruments are arranged outside the upper parts of the supporting plates. The testing device for bending around an axis provided by the utility model is reasonable in structure, compact in space, low in producing and manufacturing cost, convenient to install, and high in bending effect.
Description
Technical field
The utility model relates to the applied welding joint bending property detection of a kind of pressure vessel manufacturing device, is specifically related to a kind of bend test device.
Background technology
In the pressure vessel manufacturing, often detect test piece for welding (such as Product jointing test plate (panel), qualification of welding procedure test plate (panel), welder qualification test etc.) bending property.By bending property detection, can check the plasticity of metal material and weld metal, also can check the compactness of weld metal.Final welder's technical ability of differentiating welding technology or this test plate (panel) representative qualified foundation that provides whether is provided.Take qualification of welding procedure test plate (panel) bending test standard GB/T2653 as example, bend test device commonly used is three fulcrum types.In the bending test process, because detected test specimen is unfixing, test specimen can horizontally slip on two fulcrums below, after bending test, usually can obtain underproof bend specimen, causes the bending test sample defective, can't judge conclusion (of pressure testing).Especially, when the test plate (panel) that the two block of material soft or hards that form test plate (panel) differ greatly, such as the test plate (panel) of Q345R and S30403 material composition, underproof crooked result also usually can appear in its bend specimen.The test plate (panel) that both sides material soft or hard differs greatly, as get the longitudinal bending sample, will increase at least 3 times test piece for welding length, increase manufacturing cost.Do not have angle of bend not have indicating device, test findings is easily controversial.Do not have the bend specimen locating device, test findings easily produces fried dough twist distortion sample.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of rational in infrastructure, and the space is compact, and manufacturing cost is low, and is quick for installation, bending effect good around the bending shaft test unit.
Technical scheme: in order to solve the problems of the technologies described above, described in the utility model a kind of around the bending shaft test unit, it comprises base plate, on described base plate, be provided with bend test device, the angle of bend indicator that described bend test device comprises two support plates, be located at test specimen clamp device between the two support plate bottoms, be located between the two support plate tops U-shaped, be provided with angle sheave and flexual center axle in the middle of described U-shaped opening, be provided with boosting-rod and be located at described support plate upper outside face in described U-shaped outside.
Described U-shaped is connected with support plate by the flexual center axle.
Described angle sheave and U-shaped interconnect.
Described boosting-rod can rotatablely move counterclockwise.
One end of described support plate is semicircle shape.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts the test specimen clamp device, can guarantee that bending specimen can not twist, slide in process of the test.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
1, base plate; 2, bend test device; 3, support plate; 4, test specimen clamp device; 5, U-shaped; 6, angle sheave; 7, flexual center axle; 8, boosting-rod; 9, angle of bend indicator
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, described in the utility modelly a kind ofly belong to the applied welding joint bending property detection of pressure vessel manufacturing device around the bending shaft test unit, it comprises base plate 1, be provided with bend test device 2 on described base plate 1, described bend test device 2 comprises two support plates 3, be located at the test specimen clamp device 4 between two support plates, 3 bottoms, be located at U-shaped 5 between two support plates, 3 tops, in the middle of described U-shaped 5 opening, be provided with angle sheave 6 and flexual center axle 7, the angle of bend indicator 9 that is provided with boosting-rod 8 and is located at described support plate 3 upper outside faces in described U-shaped 5 outsides; Described U-shaped 5 is connected with support plate 3 by flexual center axle 7; Described angle sheave 6 interconnects with U-shaped 5; Described boosting-rod 8 can rotatablely move counterclockwise; One end of described support plate 3 is semicircle shape.The whole operating process of the utility model is as follows, at first be partitioned into bending specimen at test plate (panel), and according to standard-required, remove weld reinforcement with machining process, do not injure simultaneously mother metal as far as possible, do mark at distance test plate (panel) weld seam center gauge set a distance, with 0 ° of angle of bend indicator pointer indication, then bending specimen is inserted between flexual center axle and the angle sheave along orienting lug, test specimen to be bent is used the test specimen clamp device to the precalculated position, and bending specimen is fixed, rotate counterclockwise boosting-rod, angle indicator pointer to be bent is indicated to 180 °, stops reinforcing, unclamps the test specimen clamp device, take out bend specimen, bending test is finished.The utility model gained bending test sample can guarantee that the deviation at weld seam center is no more than 1mm, and the bend specimen qualification rate can reach 100%.The utility model adopts the test specimen clamp device, and flexual center axle and angle sheave can guarantee that bending specimen can not twist, slide in process of the test, adopts the angle of bend indicator, can accurate reading, guarantee that the result is accurate.The utility model is rational in infrastructure, and the space is compact, and manufacturing cost is low, and is quick for installation, and bending effect is good.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
