Full-automatic mould-pressing demoulding penetration resistant testing machine

Abstract

The invention relates to a building material testing machine. The existing penetration resistant testing machine has poor automation degree, high labor power consumption and long side surface wax sealing production time of specimens, the sealing performance can not be absolutely guaranteed, and the test work efficiency and the data precision are affected, so test mould sleeves distributed around a main oil cylinder have large upper mouths and small lower mouths, the specimens are assembled and disassembled above the test mould sleeves, an oil bag fastening type sealing structure is arranged between the test mould sleeve and the specimen to replace wax sealing, each mould sleeve is respectively connected with an automatic oil pressure system and an automatic water pressure system, and the whole test process is controlled and recorded through a automatic control system. The testing machine disclosed by the invention has the beneficial effects that a large amount of labor power is saved, the test is rapid and smooth, the test data is accurate and reliable, and integrated management and data uploading can be realized.

Description

technical field [0001] The invention relates to the field of material testing machines, in particular to building material testing machines. Background technique [0002] It is very important for building materials, especially the performance test of cement concrete blocks. Whether the experimental data is correct or not directly affects the safety and service life of the building. The permeability resistance of building materials is one of the properties that must be tested for building materials. [0003] The currently commonly used anti-penetration test requires the test block to be made into a truncated cone, and a layer of sealing layer should be made on the cone surface so that the water can penetrate from top to bottom and prevent from penetrating from the side to the outside. The first layer is the paraffin wax sealing layer. First, heat the paraffin wax until it is completely melted, and then roll the conical surface of the test block in the melted paraffin wax for...

Problems solved by technology

[0003] The currently commonly used anti-penetration test requires the test block to be made into a truncated cone, and a layer of sealing layer should be made on the cone surface so that the water can penetrate from top to bottom and prevent from penetrating from the side to the outside. The first layer is the paraffin wax sealing layer. First, heat the paraffin wax until it is completely melted, and then roll the conical surface of the test block in the melted paraffin wax for a week. The whole process of waxing takes more than 1 hour, which is very cumbersome, and small air holes may appear, and then the test block is loaded. Inside the test piece, the test piece of the anti-permeation machine is cone-shaped with a small opening on the top and a large opening on the bottom. When the test piece is molded, it is manually loaded from bottom to top, and then fixed with multiple nuts. Generally, there are six on the testing machine divided into two rows. Arranged test pieces, so the work of loading and unloading the test blocks is very heavy, the test data is recorded manually, and there is no data upload function, which is time-consuming and labor-intensive because the manual operation cannot guarantee the sealing of each test piece, which affects the efficiency of the test work and the accuracy of the data. Many laboratories are suspected of deliberately missing or not checking, which brings major hidden dangers to the quality of the project
