Abstract
The invention relates to a spool bending test set which comprises a bottom plate. A bending testing device is arranged on the upper surface of the bottom plate and comprises two support plates, a test piece clamp, a U-shaped rack, a guide wheel, a bent mandrel, a stressing bar and a bending angle indicator, wherein the test piece clamp is arranged between the lower portions of the two support plates, the U-shaped rack is arranged between the upper portions of the two support plates, the guide wheel and the bent mandrel are arranged in the center of an opening of the U-shaped rack, the stressing bar is arranged outside the U-shaped rack, and the bending angle indicator is arranged on the outer side of the upper portion of each support plate. The spool bending set is reasonable in structure, compact, low in production cost, quick to mount and effective in bending.
Description
Technical field
The present invention relates to the applied welding joint bending property detection of a kind of pressure vessel manufacturing device, be specifically related to a kind of bend test device.
Background technology
In the pressure vessel manufacturing, often detect test piece for welding (like product test piece for welding, qualification of welding procedure test plate (panel), welder qualification test etc.) bending property.Through bending property detection, can check the plasticity of metal material and weld metal, also can check the compactness of weld metal.Be final welder's technical ability of differentiating welding technology or this test plate (panel) representative qualified foundation that provides whether.GB/T2653 is an example with qualification of welding procedure test plate (panel) bending test standard, and bend test device commonly used is three fulcrum types.In the bending test process, because test specimen to be detected 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 of forming test plate (panel) differ greatly, like 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 controversial easily.Do not have the bend specimen locating device, test findings is easy to generate fried dough twist distortion sample.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of rational in infrastructure in order to overcome deficiency of the prior art, 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; Of the present invention a kind of around the bending shaft test unit; It comprises base plate; On said base plate, be provided with bend test device, the angle of bend indicator that said bend test device comprises two support plates, be located at test specimen clamp device between the two support plate bottoms, be located at U type frame between the two support plate tops, in the middle of the opening of said U type frame, be provided with angle sheave and flexual center axle, be provided with boosting-rod and be located at said support plate upper outside face in said U type frame outside.
Said U type frame is connected with support plate through the flexual center axle.
Said angle sheave and U type frame interconnect.
Said boosting-rod can rotatablely move counterclockwise.
One end of said support plate is a semicircle shape.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention adopts the test specimen clamp device, can guarantee that bending specimen can not twist, slide in process of the test.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1; Of the present inventionly 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; On said base plate 1, be provided with bend test device 2, the angle of bend indicator 9 that said bend test device 2 comprises two support plates 3, be located at test specimen clamp device 4 between two support plates, 3 bottoms, be located at U type frame 5 between two support plates, 3 tops, in the middle of the opening of said U type frame 5, be provided with angle sheave 6 and flexual center axle 7, be provided with boosting-rod 8 and be located at said support plate 3 upper outside faces in said U type frame 5 outsides; Said U type frame 5 is connected with support plate 3 through flexual center axle 7; Said angle sheave 6 interconnects with U type frame 5; Said boosting-rod 8 can rotatablely move counterclockwise; One end of said support plate 3 is a semicircle shape.Whole operation process of the present invention is following, at first on test plate (panel), is partitioned into bending specimen, and according to standard-required, removes weld reinforcement with machining process; Do not injure mother metal simultaneously as far as possible, doing marked,, then bending specimen is inserted between flexual center axle and the angle sheave along orienting lug 0 ° of angle of bend indicator pointer indication apart from test plate (panel) weld seam center gauge set a distance; Treat that crooked test specimen to the precalculated position, uses the test specimen clamp device, bending specimen is fixed; Rotate counterclockwise boosting-rod, treat that crooked angle indicator pointer is indicated to 180 °, stops reinforcing; Unclamp the test specimen clamp device, take out bend specimen, bending test is accomplished.Gained bending test sample of the present invention can guarantee that the deviation at weld seam center is no more than 1mm, and the bend specimen qualification rate can reach 100%.The present invention 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 present invention 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 present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
