What is a tensile testing machine
The tensile testing machine is also referred to as a universal material testing machine. It is mainly suitable for testing metallic and non-metallic materials, such as rubber, plastic, wire and cable, fiber optic cable, seat belt, safety belt, leather belt composite material, plastic profile, waterproof coil, steel pipe, copper material, profile, spring steel, bearing steel, stainless steel (and other steels with high hardness), castings, steel plates, steel strips, tension, compression, bending, shearing, peeling, tearing, two-point elongation (extensometer required), etc. Various tests. Different materials require different fixtures, which is also an important factor in whether the test can be carried out smoothly and the accuracy of the test results is high or lowis.
Widely used in metrology and quality inspection, rubber and plastic, metallurgy and steel, mechanical engineering electronic equipment, automobile production, textile and chemical fiber, wire and cable, packaging materials and food;
The tensile testing machine also has experiences from mechanical to electronic, from low-end to high-end, from a long period of time from simple to complex. With the maturity of measurement and control technology in recent years, however, tensile testing machines have also set off on the path of rapid development. From the perspective of corporate ownership, although mechanical tensile testing machines and hydraulic tensile testing machines still occupy most of the country, electronic or computer controlled tensile testing machines have many advantages such as accuracy, efficiency and many moreal functions Tendency to replace mechanical and hydraulic tensile testing machines extensively. Due to the mature design, reliable quality, stable performance, convenient operation and easy maintenance of mechanical and hydraulic tensile testing machines, the advantages of durability, high environmental adaptability, low running costs and reasonable price for many still have advantages that should not be underestimated User. Whether the electronic tensile testing machine can completely replace the mechanical and hydraulic tensile testing machines is therefore not easy to assess, at least in the short term.
Due to the myriad types of natural and man-made materials and the vast differences in mechanical properties between metallic and non-metallic materials, tests vary widely. Test load specifications are set by Natur formed machine products There are small force testing machines for testing the tensile strength of fibers or fiber bundles, small force testing machines for testing leather, paper and plastics, and large tensile testing machines for testing the tensile properties of metallic materials and products. Such as steel strand tensile testing machine, wire rope tensile testing machine, anchor chains -Tensile testing machine, etc. Therefore, the structural designs of testing machines with different specifications are also different, which is mainly reflected in the measurement structure and main body of the fuselage. If after the testing machine, the force measurement structure is characterized by -2. These testing machines can be mainly divided into two types: mechanical and electronic.The force measurement principle is the structure pendulum type, inclined plane, lever type and other structures The tensile testing machine belongs to the mechanical tensile testing machine category: the tensile testing machine with load sensor, displacement and deformation measuringsensor components as the measuring device structure belongs to the electronic tensile strength testing machine. According to the drive mode of the testing machine, the testing machine can be divided into hydraulic drive, electric drive and gravity drive. According to the installation method, the testing machine can be divided into vertical testing machine and horizontal testing machine.
