Description

Technical field [0001] The present invention relates to the field of geological mechanical model tests, and more particularly to geological mechanical model tests similar material automatic molding devices and production systems. Background technique [0002] Geological mechanics model test is a common means of analyzing engineering issues, usually combined with numerical trials, theoretical analysis, and jointly explore the mechanism of engineering issues. The similar material ratio trial is a key step in geological mechanical model test, and the test results are related to the accuracy and research conclusions of the test data. The similar material ratio test process is cumbersome and meticulous and meticulous, and a large number of different ratios are needed, and then the mechanical test is repeated, and it can eventually obtain the qualified material ratio. [0003] At present, there are major problems in the production of test pieces: [0004] 1, test piece production and d...

AI Technical Summary

Problems solved by technology

[0004] 1. The production of test pieces and the selection of devices are not standardized

[0005] The production process of the proportioning test piece needs to go through multiple processes. During the implementation of each process, the selection of the test device in this process is relatively random and not standardized enough, resulting in large errors in the produced test piece. The qualification rate of the parts is low

[0006] 2. Low efficiency and high cost of test piece production

[0007] The proportioning test needs to produce a large number of test pieces. At present, the production methods of test pieces mainly include manual compaction and machine compaction, but these two methods can only make one test piece at a time, and the success rate is difficult to guarantee

Manual compaction is time-consuming and labor-intensive, and the cost of compaction with a single-axis press is high

This restricts the efficient development of the ratio test

[0008] 3. It is difficult to guarantee the uniformity of the test piece

Using the existing test piece production method, the compaction degree and forming effect of the same group of test pieces are often affected by various factors such as the tester, the compaction tool, the timing of adding materials, etc. The discreteness directly affects the accuracy of the proportioning test

[0010] 4. The detection of finished test pieces is limited

[0011] After the test piece is made and formed, the size of the test piece is generally measured manually with a ruler, which is inconvenient to measure, and the test piece is easily damaged during the measurement process, and the measurement accuracy is low

[0012] The above problems restrict the production efficiency and test effect of the proportioning test piece, reduce the accuracy of the proportioning test, and affect the reliability of the model test
