Processing mould of test piece for self-unloading type analog simulation test and operation method thereof

Abstract

The invention discloses a processing mould of a test piece for a self-unloading type analog simulation test and an operation method thereof. The processing mould is used for processing a cylindrical test piece. The processing mould comprises a base, a cylinder, a constraint sleeve pipe, a top gasket, a bottom gasket, and a bearing steel column. The processing mould is characterized in that a slidegrooved rail is arranged on the base; the cylinder is a hollow circular truncated cone, a toothed rail is carved in the external side of the cylinder, a cylinder space is arranged in the cylinder; the cylinder is divided into two parts along a central axis; the edges of lower parts of each part are both provided with a grooved rail slide block; the cylinder is placed on the base, the grooved railslide blocks are clipped into the slide grooved rail of the base; the constraint sleeve pipe is provided with a gear and a rotary handle and sleeve on the external side of the cylinder, the gear is engaged with the toothed rail of the cylinder; the top gasket and the bottom gasket are both a hollow pillar, a spring and an elastic valve are arranged in the hollow pillar, the top gasket and bottomgasket are respectively arranged on the top and bottom of the cylinder, and the bearing steel column is arranged on the top gasket. The automation of demoulding of a test piece is realized, the damagerate of a test piece is reduced during the demoulding process, and the manufacturing efficiency is improved.

Description

technical field [0001] The patent of the invention relates to a mold for processing a test piece, in particular to a mold for processing a self-unloading similar simulation test piece. Background technique [0002] With the continuous development of the subject of geotechnical engineering, the engineering problems faced by people have become more and more complex. In the process of researching and solving these problems, methods similar to simulation tests have been widely used by the majority of geotechnical engineering workers. The manufacture and testing of similar simulation material specimens is an important part of similar simulation tests. The efficiency and quality of specimen processing and production will directly affect the efficiency and even success of the entire similar simulation test. Therefore, it is very necessary to explore and research a mold that can efficiently manufacture and process parts that meet the test requirements and its use method. [0003] W...

AI Technical Summary

Problems solved by technology

[0003] When conducting research on the strength test of materials for similar simulation tests, the application of traditional specimen processing molds often has the following technical problems: (1) The efficiency of making cylindrical specimens directly from ordinary cylindrical steel pipes is low, and the production cycle of specimens is long ; (2) The tolerances between different test pieces are large, and defects are prone to exist during production, resulting in large errors in the measured mechanical indicators, which do not meet the test requirements; (3) When the strength of the test pieces is low, when removing the formwork It is easy to cause damage to the test piece, and the pass rate of the test piece is low
