Description
Technical Field
The invention belongs to the technical field of coal-like rock material test piece manufacturing, and particularly relates to a method and a system for rapidly manufacturing coal-like rock material test pieces in batches.
Background
The preparation process of the coal-like rock material test piece comprises the following steps: stirring and uniformly mixing the materials, pressing and forming the materials through a die, demolding and standing and maintaining the materials.
Firstly, for material stirring and uniformly mixing, a manual stirring method is mostly adopted at present, and the method is time-consuming and labor-consuming and has poor stirring uniformity.
Secondly, for compression molding by a mold, manual tamping or hydraulic press compression is currently adopted. The manual tamping method comprises the following specific implementation processes: firstly, filling the proportioned similar materials into a mould; then manually tamping by a hammer; the compaction device is low in speed, time-consuming, labor-consuming, uneven in compaction force of the test piece, and incapable of guaranteeing the compaction degree of the test piece; meanwhile, the tamping difference of different test pieces is larger. The specific implementation process of the pressing of the hydraulic press is as follows: firstly, filling the proportioned similar materials into a mould; then placing a die pressing head on the die; and then compacting and forming by setting pressure by a hydraulic press. Although the hydraulic press presses similar materials to control the pressure so as to solve the problem of compactness of the test piece, the forming speed is too slow to meet the manufacturing requirement of a large number of test pieces made of similar materials in a short time, and the manufacturing period of the test pieces is long.
And for demoulding, at present, manual demoulding is mainly carried out by knocking the surface of the mould shell through a small rubber hammer, so that the test piece is separated from the tight joint surface of the mould under the vibration of the mould shell, and finally the test piece is taken out. The manual demoulding is carried out, the force of each knocking is different, the force is too large, so that the micro cracks are generated in the test piece in the demoulding process, the reliability of the subsequent test is affected, and the test piece is not easy to separate due to too small force. In addition, the model test has larger requirement on the test piece quantity, and the manual method has longer test piece manufacturing period and wastes time and labor. Meanwhile, for the manufacturing of molded coal test pieces, as pulverized coal particles are finer in the pressing process and are in close contact with the inner surface of a die, the test pieces are easy to break from the middle in the demolding process, and the success rate of manufacturing the test pieces is greatly influenced.
Finally, for standing maintenance, at present, the test personnel lack attention on the maintenance of the test piece, the test piece manufactured and molded is generally directly exposed in the air, and uncontrollable factors such as indoor and outdoor temperature and humidity have great influence on the test piece.
In view of the foregoing, in order to meet the needs of experiments, there is a need for a system that can save time and effort and can rapidly manufacture a sample of similar material of coal-like rock,
