Technical introduction of steel strand static load tensile testing machine

As the core raw material in the fields of prestressed engineering, road and bridge infrastructure, and rock and soil support, the stability of its mechanical properties is directly related to the construction quality and structural reliability. The static tension testing machine for steel strand is a special mechanical testing equipment specially designed for prestressed steel strand, anchor cable, wire rope and other materials, which can stably complete static tension testing and provide accurate data support for material quality inspection and engineering compliance acceptance.
First, the core content of equipment testing
The equipment adopts static uniform loading mode, which can accurately collect all core force values and performance indexes during the stretching process of steel strand, with stable data and high repeatability. The main testing contents include:
1. Maximum test force (ultimate tensile force): testing the maximum load borne by the sample before tensile fracture is the core basis for judging the mechanical properties of the material and can be used to calculate the tensile strength of the material;
2. Specify the non-proportional extension force: accurately collect the force value corresponding to the small amount of plastic deformation produced by the sample, and provide effective reference for the prestressed tensioning design of the project and the grading of material properties;
3. Synchronous detection and calculation of key parameters such as elongation after fracture and elastic modulus of samples can fully meet the requirements of quality inspection, spot inspection and scientific research.
The overall test flow of the equipment conforms to the general testing standards of the industry, and the test data can be retained, exported and reported in a standardized way, which meets the compliance acceptance requirements of various testing scenarios.
Second, the equipment structure and technical advantages
This machine adopts four-column rigid fuselage structure, which has strong overall stability and high bearing capacity, and is not easy to deform in long-term test, thus ensuring the stability of the precision of large load tensile test. With the mature electro-hydraulic servo control system, the loading is uniform and stable, which can effectively avoid the fluctuation of test data.
The equipment is equipped with a special customized wedge-shaped clamping fixture, which has high clamping fit, can effectively avoid the problems of sample slipping, pinching and premature fracture, and ensure the standardized test process and true and effective data. The fuselage is equipped with safety protection structure, which can effectively avoid potential safety hazards during the test and ensure the safety of operators.
Equipped with a special measurement and control system, it can display the test force value and deformation curve in real time, automatically collect data and calculate performance parameters in the whole process, without manual repeated accounting, which greatly improves the test efficiency and adapts to the batch detection and refined scientific research test scenarios in the laboratory. After replacing the corresponding tooling, it can be compatible with the tensile testing of various profiles such as anchor cables and wire ropes, and the equipment has strong versatility.
Third, the main application areas
The equipment is widely used in steel strand production enterprises, third-party engineering inspection institutions, road and bridge infrastructure laboratories, geotechnical engineering support inspection units and university research institutes, and can carry out the work of pre-stressed steel strand incoming inspection, type inspection, sampling re-inspection and so on in a normal way, which provides reliable technical support for material quality control of infrastructure projects.
Fourth, the application value of equipment
Through the standardized and high-precision static tensile test, it can effectively verify whether the mechanical properties of each batch of steel strand materials meet the standards, control the quality of raw materials from the source, avoid the hidden dangers caused by the substandard materials, help all kinds of prestressed infrastructure projects to achieve standardized and standardized quality control, and provide reliable data guarantee for the stability and long-term use of engineering structures.
