Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of packing uniform standard cylindrical specimen batch die mould general combined mould.
Background technology
In large-scale Geotechnical Engineering Project design, need to analyze the stability of engineering structure.General after geologic prospect, obtain the physical and mechanical property of Rock And Soil, carry out the numerical simulation based on Computational Mechanics on this basis, or based on the physical analogy of similar three laws, sometimes, be obtain more reliable stability conclusion, also two kinds of methods are used simultaneously, verify each other.
During physical analogy, need to select analog material, make standard specimen according to certain proportioning, carry out Mechanics Performance Testing, then utilize selected proportioning and composition, make large-scale geomechanics model, observe.The Forming Quality of standard specimen directly determines the stability conclusion of final geomechanics model.
The Mechanics Performance Testing object of usual routine obtains the parameters such as elastic modelling quantity, Poisson's ratio, tensile strength, compression strength, angle of friction and cohesive force, consider the discreteness of obtainable most multiparameter and experimental result in same experiment, the standard specimen quantity under same proportioning must not be less than 6.These type facility of will hoping for success need higher efficiency.
For standard specimen, except geometry is necessary consistent with composition, also require that packing is wanted evenly.The briquetting pressure that real technique is difficult to ensure that it is stable is manually hit in traditional dependence, and packing has very large randomness.Monomer split cavity common in all kinds of document and research report, monomer cylinder mold coordinate the screw drives tamping mechanisms such as queen post, three pillar type, four-column type, to a certain extent, than manually hitting tangible packing and press power control aspect has superiority; If rely on forcing press pressurization, then can real time and determine amount control press power, packing has and significantly promotes further.But, only use forcing press, and shaping mould do not designed, test specimen still may be caused different in axis direction packing.
Practice shows: disposablely load material in a mold, suppress vertically, press power can by storeroom and between material and mould wall frictional force consume, the actual press power along axis can successively decrease, cause near pressure head side, packing is large, and away from pressure head, then packing is little, axial length is longer, and difference is larger.For multimode assembling die, except pressure head reason, the space geometry arrangement of each mould, also can cause press power uneven distribution, and then, also cause packing and the physico mechanical characteristic inequality of test specimen.If mould and forcing press adaptation can be embodied as, and two-way compacting when compressing, each mould equal pressure loads, and disposable multimode is shaping, and the problems referred to above can be readily solved.
Utility model content
The purpose of this utility model is to provide one can be adaptive with ordinary press, cylindricity is good, two-way compacting, packing is even, press power is even, one man operation, the assembling die that disposable batch is shaping, solve that standard specimen shaping packing is uneven, batch success rate is low, with the unmatched problem of universal press.
In order to achieve the above object, the utility model has following technical scheme:
A kind of packing uniform standard cylindrical specimen batch die mould general combined mould, comprises perforate cover plate, positioning disk, hopper and base.Described perforate cover plate, positioning disk, successively with hopper with base is corresponding arranges, vertically coordinate location by mutually corresponding dowel hole and pin from top to bottom; Also comprise die cylinder, described die cylinder enters from perforate cover plate, is vertically positioned the counterbore on hopper; Also comprise back-up ring, described back-up ring is positioned at hopper central authorities; Also comprise conversion seaming chuck, common pressure head, movable long pressure head, movable short pressure head and conversion push-down head, with the hole one_to_one corresponding of size behind described all pressure heads and location.
Wherein, respectively there are 6 through holes at the bottom of described perforate cover plate, positioning disk and hopper, equidistantly arrange radially, but aperture is less than positioning disk aperture on cover plate, hopper is open at one end, the hollow cylinder that one end is closed, be stepped hole at the bottom of blind end hopper, aperture is identical with cover plate aperture; Three parts are by the hole of correspondence, finger setting.
Wherein, described die cylinder is hollow circular-tube, and external diameter is identical with positioning disk aperture, can pass in and out, but can not pass in and out from cover plate and hopper, and there is cutting edge one end from guiding disk hole.
Wherein, described back-up ring is hollow circular-tube, identical with die cylinder height, and hopper, much larger than die cylinder, can be divided into material district and loading zone by external diameter.
Wherein, described transfer head is multidiameter, and footpath broad in the middle section plays spacing and carrying effect; Two ends path section Length discrepancy, external diameter is equal with usual pressure compressing head, can pass in and out from base medium pore, and long section is highly slightly less than movable long pressure head.
Wherein, described movable ram is the solid cylinder that the external diameter of long and short two kinds of specifications is slightly less than die cylinder internal diameter, totally 12.
Owing to taking above technical scheme, the utility model has the advantage of:
1. two-way compacting vertically, shaping test piece packing is even.
2. by transfer head, can be adaptive with ordinary press, press power realizes fixing quantity, and highly versatile, be suitable for promoting.
3. mould arranges radially on disc seat, and each loose pattern press power is even.
4. shaping 6 test specimens of disposable batch, homogeneity is good, and shaping efficiency is high.
5. mold integral compact conformation, easy disassembling, carrying convenience, simple to operate.
6. shaping rear standard specimen linearity and cylindricity good.
