To the final product application of driving rod from the bridge parts, metal materials need to have high strength and elasticity, and can not break in bending load. The mechanical properties of metal materials (such as strength, ductility, hardness and fatigue) is an important measure of the bar, is also an important basis for judging whether it is suitable for a particular application.
Mechanical performance testing metal bar (metal tensile testing machine)
A circular or rectangular bar can be processed into various products. The bar usually processed into other shapes of steel, in order to meet the requirements of industrial production and final product application. To the final product application of driving rod from the bridge parts, metal materials need to have high strength and elasticity, and can not break in bending load. The mechanical properties of metal materials (such as strength, ductility, hardness and fatigue) is an important measure of the bar, is also an important basis for judging whether it is suitable for a particular application.
The mechanical properties of tensile test for the development or evaluation of metal materials provide a relatively simple and low wood technology, it can provide relevant information on metal and alloy material mechanical load response. In some cases, manufacturers can test and the final product is very close to the. In other cases, it must be cut or folding of raw materials. On the two types of test materials in comparison, inspection and quality control of alloy development is feasible. Bar sample tests need to consider many important factors, such as stiffness, moderate clamping force, specimen alignment, strain measurement, equipment control, data collection and reporting of results. The height of the rack and the fixture selection are particularly important when the heavy bars are tested under extreme load conditions..
In order to meet the requirements of test fixture material, the company provides a series of flat type, V type or special fixture. Most of the wedge clamp is provided with a front opening type design, and is provided with a shoulder end and a threaded end sample tool. The design of the split sleeve for the shoulder end sample is designed to accelerate the progress of the production field test.
The bending test provides important information about the plasticity and toughness of the material. The applicability of test materials is required. Because of the variety of materials, samples and applications, and the continuous development of materials science, it is necessary to develop a special test fixture.
Based on the diameter of the specimen and the bending diameter. Bending fixture provides adjustable bearing span and mind bending can be replaced, so a single fixture can used in a variety of sizes bar tests.
A number of applications and products are designed to be affected by the shear stress of the bar. These applications from simple pin and U hook adapter to the safety pin as protection of mechanical safety of expensive equipment. Therefore, it is necessary to understand the properties of the bar in the actual shear conditions.
Compression shear and tension shear test fixture
Single shear and double shear test fixture.
Torsion test can test the maximum shear modulus, shear modulus, shear strength and fracture characteristics of plastic and other materials. To determine the material properties, the need for accurate measurement of torque and torsion angle in the fixed ruler. Although seemingly simple, but because the bar clamping torsion test is often difficult to increase the difficulty of the test, and is not easy to measure the torsion angle. Samples often need to be processed into the middle of the area is small, the clamping end two or hexagon.
To get the accurate results and maintain fixture specimen on vital. During the test of circular sample is difficult without sliding clamp. Chuck type torsion fixture, round, hexagonal or two angle shaped specimen.
