Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the small-sized bending of sheet-like material of the present invention be with changing brace type experiment pressing element, utilizes and is installed on the universal press.Form a complete set of by top pressure head 3, the slidably block 5 that can change support bar 4, fixed support and 7 four kinds of members of base and to constitute.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, top pressure head 3 is made up of drift 301 and connecting link 302 integral body.Drift 301 is a duck, and duck drift 301 upper ends are connecting link 302, and the lower end head is the semicircle arcuation.Connecting link 302 end cross are provided with the peg perforation, and pressure head 3 is connected with the four-way union 1 of universal press load bar by peg 2 through the peg perforation.
Like Fig. 1, Fig. 2, shown in Figure 3, can change support bar 4 and be provided with symmetrical two, its cross section is the section shape of checker shape, and top 401 sections are circular arc, and bottom 402 sections are taper type.The slidably block 5 of fixed support is provided with two of symmetry.The slidably block 5 of each fixed support is made up of the perpendicular body 501 peaceful bodies 502 that the longitudinal profile is the L type; It is planar that perpendicular inboard, body 501 top is the slope; Perpendicular body 501 tops vertically are provided with and can change the consistent taper type groove of support bar 4 bottom frustum shapes, and flat body 502 is provided with bolt hole.Each can change support bar 4 and pass through bottom frustum difference sliding plug in the taper type groove of the slidably block 5 of two fixed supports.Slidably block 5 bottom surfaces of fixed support and the upper surfaces level of base 7 are fitted and connected.Slidably block 5 bottoms of fixed support are connected a trapezoidal slide block 9 through the bolt hole on the flat body with bolt 6.Base 7 is a prolate bar cuboid, and to having a trapezoidal sliding-rail groove, trapezoidal slide block 9 and trapezoidal slide block 9 consistent with trapezoidal sliding-rail groove shape is slidingly connected in the trapezoidal sliding-rail groove along long in base 7 upper surface centers.Base 7 bottoms are provided with connecting link 8.Connecting link 8 is connected with universal press lower clamp seat 10 through peg.Ruler is posted in base 7 sides, and ruler is used for adjusting the spacing by requirement of experiment of the slidably block 5 of fixed support, with guarantee experimental data accurately.
The slidably block 5 of fixed support can linear slide in the trapezoidal sliding-rail groove of base 7 through trapezoidal slide block 9, with the spacing of the slidably block 5 that changes two fixed supports.
The drift 301 of top pressure head 3 lower ends and the arc radius size that can change support bar 4 tops 401 can be made a plurality of specifications according to requirement of experiment; When carrying out different-thickness material cripping test; Need not whole supporting mould is changed, only need from taper type groove notch, take off changeing support bar 4 horizontal pushing away; The support bar 4 that newly can change that Pass Test requires is aimed at taper type groove notches and is pushed into consistent the getting final product of slidably block 5 vertical planes with fixed support, and dismounting is extremely easy.If later test also needs the support of different radii, the changed support bar 4 that only need process this radius gets final product, and need not to process whole lower support member, thereby reduces the input of cost economically.
Can change the existing radiuses of support bar 4 and be two kinds of 2.0mm and 5.0mm.Can change support bar 4 bottoms is taper type, purpose keep during for pressurized supporting stable.
The top pressure head 3 that test specimen require to load, can change support bar 4 and test specimen to support bearing surface be the cylinder curved surface, top pressure head 3, the slidably block 5 that can change support bar 4 and fixed support all adopt No. 45 steels to do.Slidably block 5 spacings of fixed support can be adjusted according to the difference of test material, to be applicable to the cripping test of other sheet-like materials.
It is planar that perpendicular inboard, body 501 top is the slope, and this kind design mainly is the slidably block 5 right angle parts that test specimen touches fixed support when being afraid of test, influences test figure.Address this problem though can take to change the outer in-migration of support bar grooved rail, consider that grooved rail moves meeting outward and reduces fixed stop outer ledge intensity, possibly cause the support bar unstability at the trial, so do not take this kind design.Slidably block 5 bottoms of fixed support are connected with its base 7 caulking grooves, and promptly slidably block 5 bottoms of fixed support are provided with trapezoidal slide block 9, embed in the trapezoidal sliding-rail groove of base 7.And the flat body 502 of the slidably block 5 of fixed support is provided with bolt hole, and in order to erection bolt 6, and it is firm to adjust slidably block 5 location of fixed support of spacing by requirement of experiment through bolt 6.
The test specimen overlap joint can be changed above the support bar 4 at two, start universal press, charger drives top pressure head 3 through four-way union and moves down, and 301 pairs of test specimens of drift load testing experiment and the evaluation that can carry out new material.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
