Description

A kind of Effective model testing standard test specimen processing mold

Technical field

The utility model relates to a kind of processing molds that test specimen is tested for making analog simulation, more particularly to one kind is efficiently Model test standard specimen processing mold.

Background technique

Currently, the engineering field of rock mechanics rapidly develops, under Large Underground Structure, surface mining and hard situation The execution conditions that face of roadway opening it is increasingly sophisticated changeable, propose bigger challenge, to engineering safety in order to grasp work The deformation behaviour of Cheng Yanti, it is necessary to which mould is carried out to mechanical behaviors such as mechanical characteristics and deformation such as stability, the intensity of rock Quasi- research.

Analog simulation test be a kind of using the principle of similitude as the laboratory procedure of foundation, have low cost, the period it is short, The advantages that height emulation, it is widely used in the fields such as mining, geology and geotechnical engineering, it has also become a kind of Study of The Underground engineering problem Strong scientific research means.Based on analog material, analog material mechanical property allows for true anti-model test Reflect the stress deformation feature of test prototype, it is necessary to meet model test similarity law, the data simulated in this way could really have Effect, therefore the selection of model test analog material determines the success or failure of test.However, nature difficulty has a kind of mechanical property of material Meet the ideal model test material after the likelihood ratio converts, but need to obtain meeting model by multiple material allotment mixing Test the material of the likelihood ratio.A kind of development mixing analog material, will match through hundreds and thousands of groups of proportioning tests, and by each group Be made standard mechanics test specimen, the variation of research material proportion to the Effect on Mechanical Properties rule of mixing analog material, and then develop and Select the mixing analog material with corresponding mechanical property.

Material mixture ratio length experimental period, task weight, the production of standard specimen are more crucial in material mixture ratio experimentation A step, make the precision and efficiency of test specimen, leverage the process entirely tested, according to test requirements document, the examination of same batch Part must be suppressed uniformly, and guarantee sample dimensions precision, and the processing and fabricating mold of existing test specimen has in actual use Inefficiency, disassembly is cumbersome, therefore the disadvantage of test specimen production precision deficiency develops a kind of Effective model testing standard test specimen Processing mold is very necessary.

Before the utility model, application No. is a kind of similar materials of 2015104914957 disclosure of the invention at The quick molding method of type die assembly and its standard specimen, wherein die assembly includes pedestal, big cutting ferrule, internal model and lesser calorie The round pressure-bearing cover board of four parts and a centre with cylindrical protrusions, internal model bottom and bottom plate is covered to insert at interference fit It connects, size cutting ferrule is loop type structure, is directly sleeved on by being somebody's turn to do on identical left and right internal model outer wall dimerous Device, which passes through round pressure-bearing cover board, to suppress test specimen on analog material that the pressure of press machine is effectively transferred in internal model cavity.It tears open When mould, the outer peripheral surrounding of pedestal is tapped using hand hammer and is separated to pedestal with internal model, takes out molded test specimen, but its internal model is Two parts split modular structure, it is big with test specimen contact area, if adhesive strength used in test specimen is larger, easily make test specimen and mold Adhesion, demoulding are difficult；Since the intensity of analog material test specimen is lower, it be easy to cause test specimen to damage tearing internal model percussion vibration open, and Two people cooperation is needed when demoulding, a people is difficult to complete the work of demoulding.

Application No. is a kind of self-tipping type analog simulation of the disclosure of the invention of 201711210306X test test specimen processing mold and Its operating method, including pedestal, cylinder body, confinement sleeve, embodiment in which top gasket, bottom gasket and pressure-bearing steel column, the device pass through rotation Rotating handles on moving constraint casing, move up confinement sleeve, gradually release its constraint to cylinder body, meanwhile, it is placed in cylinder Bullet valve in the gasket in internal portion flicks under the thrust of spring, and cylinder body is pushed to separate automatically to the left and right.If analog material uses When the adhesion strength of binder is larger, for mold together with test specimen tight bond, cylinder body can not be flicked by playing valve, and demoulding is caused to lose It loses；When furthermore manually loading analog material, it may occur however that shedding causes it to fall into sliding grooved rail, stops the promotion of cylinder body, increases The complexity of demoulding work；This mold can only carry out the compacting of single test specimen, therefore compacting test specimen efficiency is lower, fabrication cycle It is long.

Existing defect is invented for above, it is efficient and convenient and can be carried out batch test specimen and be pressed into invent a kind of dismounting mold The test specimen processing mold of type is necessary.
