Detailed description of the invention
As shown in Fig. 1-Figure 10, a kind of resistance to compression test piece preparation dress, comprise base 3, ring mould 2, guide post 1 and formed clamp plate 5, the lower end of guide post 1 is connected to ring mould 2, upper end is also fixed by nut 4 through formed clamp plate 5, base 3 and ring mould 2 are bolted, and are also provided with demoulding push rod 6 between base 3 and ring mould 2; Described ring mould 2 is made up of the outer shroud 21 at edge and the blanking step 24 of bottom, and the center of blanking step 24 is provided with the directional hole 23 for installing guide post 1, and the surrounding of directional hole 23 is provided with multiple test piece forming hole 22, and the bottom of ring mould 2 is provided with screwed hole.
Described base comprises plectane 34, plectane is provided with the demoulding push rod installing hole 33 matched with test piece forming hole 22, the connecting hole 32 corresponding with the screwed hole of the bottom of ring mould 2, the demoulding apical pore 35 matched with demoulding push rod installing hole 33, described demoulding apical pore 35 is blind hole, size, quantity and position are consistent with demoulding push rod installing hole, and machining angle staggers.
Described base also comprises demoulding screwed hole 31, by the bottom outside of base to installing lifting bolt 7 in it.
Described guide post is straight-bar, and two ends are provided with screw thread, is provided with the positioning step matched with the directional hole of ring mould above bottom thread.
Described formed clamp plate 5 is plectane, and be the shaping end face 52 that blanking step 24 mates, the surrounding of plectane is welded with journal stirrup 51, and center is provided with the pilot hole 53 passed for guide post 1, journal stirrup 51 machined demoulding hole 54.
Described demoulding push rod 6 has shaping post 61 and locating dowel 62 to be formed by connecting, and the outside dimension of shaping column is corresponding with test piece forming hole 22, and fit clearance is 0.02mm.
During use, ring mould is buckled on base, guarantee that the bottom of connecting hole 32 and ring mould 2 is provided with screwed hole correspondence, test piece forming hole 22 is corresponding with demoulding push rod installing hole, ring mould and base is tightened with screw, at the external coating mould oil of test piece forming hole and demoulding push rod, or processing one deck anti-stick coating, the shaping column of demoulding push rod is put into test piece forming hole, and locating dowel puts into demoulding push rod installing hole, and guide post is loaded pilot hole.
Then under vacuum conditions, liquid energetic material is poured into test piece forming hole 22, waters completely until it, scrape off unnecessary material, be pressed into gently in ring mould along guide post by its pilot hole by formed clamp plate, shaping end face 52 is tightly fitted with blanking step, nut 4 of screwing on the guide bar is fixed.When the demoulding after energetic material curing molding, take off nut 4, unscrew formed clamp plate by demoulding hole 54, take off formed clamp plate.
The bolt finally separated between division ring mould and base connects, and adopt lifting bolt to be installed to demoulding screwed hole 31, separated with base by ring mould, now, the locating dowel of demoulding push rod has exposed the end face of ring mould.Overturn base again, demoulding apical pore 35 is aimed at the locating dowel 62 of demoulding push rod 6, utilize gravity, test piece 8 can be deviate from from test piece forming hole 22.
