Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the schematic diagram of sample mount in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 2, it is the anti-U-shaped bend specimen of a kind of making provided by the invention device, comprise stand 1, the upper steel plate 7 of affixed stand 1 top approximate ellipsoidal, the square lower steel plate 8 in bottom of affixed stand 1, stand 1, upper steel plate 7 and common formation of lower steel plate 8 load space, and upper steel plate 7 lower surfaces have been bolted depression bar 2, the pressure head 3 of the free end melting welding half pulley-like structure of depression bar 2, pressure head 3 can convert according to the radius-of-curvature of the external diameter of bend pipe and anti-U-bend; Stand 1 between upper steel plate 7 and lower steel plate 8 is provided with the slide plate 5 of the approximate ellipsoidal that can slide up and down along stand, and slide plate 5 is connected by sliding bearing with stand; On slide plate 5, be provided with sample mount 4, this sample mount 4 can move freely so that adjust central plane and central point on slide plate 5; Between slide plate 5 and lower steel plate 8, be provided with slide plate 5 jacking systems 6.Jacking system 6 is lifting jack, being placed on lower steel plate 8 of described lifting jack, and its bracket contacts with the lower surface of slide plate 5.
As shown in Figure 3, described sample mount 4 comprises the supporting plate 43 that is arranged on slide plate 5, is symmetricly set on two groups of shoulder framves 41 on supporting plate 43, is fixed on every group of bearing 42 on shoulder frame 41; Shoulder frame 41 is fixed by bolts in the groove of supporting plate.Wherein, the spacing of two bearings is adjustable, thereby, can make the anti-U-shaped bend specimen of different curvature radius.
Two bearing interludes are provided with limited mouth 44, and limited mouth 44 and the concentricity axle of bearing 42, can guarantee that two free ends of U-shaped pipe are parallel.
The material of described stand, depression bar, pressure head, sample mount and slide plate is all selected A3 steel, to meet the requirement of intensity; Lifting jack can adopt 1-3 ton standard component, and easy to use, cost is low.
Adopt the technical scheme of this structure, can meet and make single anti-U-shaped and two anti-U-shaped bend specimen; Simple in structure, easy to operate.Can fast to make external diameter and be 17-21mm, thickness be 1.0-1.4mm cuts open the anti-U-shaped sample of pipe; And by the distance between adjusting sample bearing, can make radius-of-curvature is the anti-U-shaped sample of 8-20mm; The depression bar adopting connects with bolt, can replacing depression bar for convenience detach, thereby for making the U-shaped sample of other specification.
While making single anti-U-shaped sample, first regulate as requested the distance between two bearings of sample mount 4, then the soft aluminium bar of the semi-cylindrical identical with cuing open bore is placed on limited mouth 44, cuing open pipe sample is placed on soft aluminium bar and with it and closely cooperates, then pressure head 3 and sample mount 5 and the central plane that cuts open pipe sample three are adjusted on same vertical plane, and the center of pressure head and the center of sample are aimed at, finally, manual slow start lifting jack, make pressure head 3 and cut open pipe sample and closely cooperate and contact, cut open pipe along pressure head 3 Slow Deformations until cut open pipe sample two free segments parallel, thereby form single anti-U-shaped sample.
While making two anti-U-shaped sample, first regulate as requested the distance between two bearings of sample mount 4, then the soft aluminium bar of the semi-cylindrical identical with cuing open bore is placed on limited mouth 44, by one, cuing open pipe sample is placed on soft aluminium bar and with it and closely cooperates, and another cut open pipe sample be placed in previous cut open pipe sample on, make two to cut open the coincidence of tube hub face, then pressure head 3 and sample mount 4 and the central plane that cuts open pipe sample three are adjusted on same vertical plane, and the center of pressure head and the center of sample are aimed at, finally, manual slow start lifting jack, make pressure head 3 and cut open pipe sample and closely cooperate and contact, cut open pipe sample along pressure head 3 Slow Deformations until to cut open pipe sample two free segments parallel, thereby form two anti-U-shaped samples.
The anti-U-shaped bend specimen of a kind of making of the present invention device is not limited to above-mentioned embodiment, and those skilled in the art's technical scheme according to the present invention draws other embodiment, belongs to equally technological innovation scope of the present invention.
