Abstract
The utility model discloses a test rack for anti-pressure performance of stabilized positive pressure material, which is composed of a hydraulic pressure machine 1, a base 2, left and right vertical posts (3,3`), and a top support bar 4. The anti-pressure performance test rack is characterized in that: a disc-shaped lifting platform 6 with a concaved spherical cavity 7 is arranged fixedly at upper end of a piston rod 5 of the hydraulic pressure machine 1, a round support plate 9 with a bottom convex spherical surface 8 is arranged in the concaved spherical cavity 7, left and right test support bases (10,10`) are arranged on the round support plate 9, the fixing handle of an anti-pressure test top press head 13 is locked into the axial lock slot 12 of a top press head fixing base 11; the middle part of the top support bar 4 is arranged fixedly with a top round pad 16 by a bolt 15. In the test rack, if the anti-pressure test top press head is deflected, the left and right test support bases can be rotated for adjustment automatically, so that pressurized action force is always vertical with the positive medium surface of test material, therefore the test rack can improve test effect and is widely applied in anti-pressure performance test of metal and non-metal materials.
Description
Technical field
The utility model relates to the improvement of a kind of metal and nonmetallic materials compressive property test stand, specifically a kind of stable malleation material compressive property test stand.
Background technology
At present, when metal and nonmetallic materials being done the compressive property test, the general compression test frame of special use that adopts is tested, the compression test frame of this special use, comprise hydropress mostly, base, a left side, right support post, the upper support whippletree constitutes, a left side, the lower end of right support post is vertically fixed on the left side of base respectively, right-hand member, the left side of upper support whippletree, right-hand member is fixed on a left side, the top of right support post, discoid lifting table is fixed in piston rod upper end at hydropress, on discoid lifting table, install two compression test bearings of symmetry, fix the compression test seaming chuck at the middle part of upper support whippletree, the compression test seaming chuck is aimed at the center position of two compression test bearings, the deficiency that the compression test frame of this special use exists is: when the compression test seaming chuck presses down, exerting oneself when big, the center of two compression test bearings can appear departing from, make the pressure of generation can not act on the center position of test material, the surface of force direction and test material is not a plumbness, therefore produces test error.
Summary of the invention
It is a kind of in the pressure process of compression test that the purpose of this utility model is to provide, and acting force vertically acts on the surface of test material all the time, thereby improve the stable malleation material compressive property test stand of test effect.
For reaching above purpose, the technical scheme that the utility model adopted is: this stable malleation material compressive property test stand, by hydropress, base, a left side, right support post, the upper support whippletree constitutes, a left side, the lower end of right support post is vertically fixed on the left side of base respectively, right-hand member, the piston rod of hydropress passes the central through hole of base, it is characterized in that on fixing on the piston rod of hydropress, having the discoid lifting table in concave spherical surface cave down, following concave spherical surface cave is located on the plate face of convex platform of discoid lifting table, placing the round pallet of being with the protruding sphere in the end in the concave spherical surface cave down, on round pallet, establish a left side, right test bearing, establish the seaming chuck holder at the middle part of upper support whippletree, on the seaming chuck holder, establish axial draw-in groove, the fixed handle of compression test seaming chuck snaps in the axial draw-in groove, and fix with the thimble of draw-in groove perpendicular to axial direction, the middle part of upper support whippletree by bolt on circular cushion block, bolt passes bolt hole on the circular cushion block and the bolt hole on the seaming chuck holder is tightened, specimen size is changed the test that in certain compression stroke, to finish, the thickness of circular cushion block can draw according to a needed SPATIAL CALCULATION of fixing physical property test, in case making the thickness of circular cushion block determines, then the piston rod adjustable height of its hydropress adapts in this test, need not to adjust the height of upper support whippletree again.The utility model is also implemented by following measure: screw thread is established in the upper end at left and right support post, the upper support whippletree is by the upper end of upper and lower fixed by nut at left and right support post, when variation is tested frequent test greatly and alternately to specimen size, select bigger compression stroke, at this moment, can adjust the height of upper support whippletree by the adjusting of upper and lower nut.When using the utility model, test material exemplar load is placed on the left and right test bearing, the primer fluid press, the compression test seaming chuck vertically is pressed in the middle part of the test material exemplar of left and right test bearing, in pressure process, if when off-centered position appears in the compression test seaming chuck, left and right test is propped up toilet and is rotated, make the component of compression test seaming chuck vertically act on the surface of test material exemplar all the time, eliminated the error that produces because of the out of plumb surface.
The beneficial effects of the utility model are: compare with the metal or the nonmetallic materials compressive property test support of present use, because can be in the applied voltage test process, if it is askew partially that the compression test seaming chuck occurs, can adjust by the rotation of left and right test bearing, make pressurization power all the time perpendicular to the surface, center of test material, therefore, can improve experiment effect.Can be widely used in the compressive property test of metal and nonmetallic materials.
