The testing machine is used to measure the mechanical properties, technological properties, internal defects and the dynamic unbalance of the rotating parts under various conditions and environments, and to measure the mechanical properties of the metal materials, non-metallic materials, physical properties of mechanical parts and engineering structures.
Test machine is divided into chemical testing machine and physical performance testing machine, between them have different functions, are used to detect their own products meet the national standards.Testing machine industry mainly produces the following eight categories of products:Metal materials testing machine;Impact testing machine: used to determine the impact of metal materials in the dynamic load under the impact of performance, in order to determine the material under the action of the nature of the load. Divided into manual impact testing machine, semi-automatic impact testing machine, digital impact testing machine, computer controlled impact testing machine;Impact test low temperature: low-temperature metal impact test is the best test sample cooling, thermal insulation equipment;Notch broaching of the impact specimen: processing specimen notches, divided into the impact of the sample notch manual broaching, the impact of the specimen gap hydraulic broaching and the impact of the sample notch electric broaching machineImpact specimen gap projector, used to detect whether the processed specimen gap qualified;Universal testing machine: mainly used for metal, non-metallic tensile, compression, bending and shear test. Test operation and data processing accord with national standard GB / T 228-2010 "metal material room temperature tensile test method" requirement, if change the structure form and change the related parts, can meet the international standards such as ASTM, ISO etc. Applicable to metallurgy, construction, light industry, aviation, aerospace, materials, universities, research institutes and other fields. Divided into digital universal testing machine, computer screen display hydraulic universal testing machine, computer-controlled electro-hydraulic servo universal testing machine2. Non-metallic materials testing machine;Hydraulic universal testing machineHydraulic universal testing machine3. Force and deformation testing equipment (force sensors, dynamometers, displacement sensors, extensometers, accelerometers, etc.);4. Package and process performance testing machine (including package drop test machine, package impact testing machine, friction and wear testing machine, bending test machine, straightening machine, etc.);5. Balancing machine (including on-site balancing instrument);6. Shaking table (including the impact of Taiwan and the impact test bed);7. Non-destructive testing equipment (magnetic particle detection machine, X-ray detection machine, γ-ray detection machine, ultrasonic flaw detector, eddy current detector, acoustic emission detector, etc.);8. Testing machine functional accessories and testing machine-related test equipment and equipment.Material testing machineMaterial testing machine definitionAccording to the national measurement technical specification of JJF1011-2006 "Force and hardness measurement terms and definitions", the material testing machine has a clear definition, refers to: the materials, parts and components for mechanical properties and process performance test equipment. Therefore, the use of different materials, materials testing machine can be tested for different mechanical properties and testing. Such as tension, pressure and universal million testing machine testing material elasticity, plasticity, strength, stiffness and other characteristics. Hardness testing machine to detect the ability of materials to resist the invasion of external force, pendulum impact testing machine to test the impact toughness of the material, and durable and creep testing machine is used to detect the material limit and creep performance.Classification of materials testing machineAccording to the People's Republic of China professional standards JB / T10059-1999 "testing machine and non-destructive testing equipment model preparation method", which involves the testing machine and non-destructive testing equipment were divided into eight categories: gold material testing machine, non-metallic materials testing machine, Force and deformation detector, friction and wear process testing machine, balancing machines, shaking table Taiwan impact, transport packaging testing machine, non-destructive testing equipment.One of the materials, parts and components for mechanical properties and process performance of three major categories of testing machines and force, deformation detector can be divided into the following categories:1. Metal material testing machine (tensile testing machine, pressure testing machine, universal testing machine, torsion testing machine, creep testing machine, lasting strength testing machine, relaxation testing machine, impact testing machine, fatigue testing machine);2. Non-metallic material testing machine (plastic material testing machine, rubber material testing machine, cement and rock concrete testing machine, wood testing machine, refractory testing machine, paper testing machine, paint coating testing machine, enameled wire cable testing machine, Testing machine, ceramic testers, interfacial tension testing machine, leather testing machine, fruit testing machine, broken tiles testing machine, fiber testing machine, etc.);3. Process testing machine is divided into (spring testing machine, cupping testing machine, bending test machine, wire torsion testing machine, Rao degree test machine, friction and wear testing machine).Universal testing machineIntroduction of digital testing machineMainly used for metal, non-metallic materials of the tensile, compression, bending and other mechanical properties of the test, increase the shear can be done with shear test. The machine is equipped with a computer, printer, electronic extensometer, photoelectric encoder and general test software, the balance wing test machine can accurately determine the tensile strength of metal materials, yield strength, the provisions of non-proportional extension strength, elongation, elastic modulus Mechanical properties. Test results can query and print (force - displacement, force - deformation, stress - displacement, stress - deformation, force - time, deformation - time) six curves and related test data, with software self - test function, See the software instructions. Is the industrial and mining enterprises, research institutes, universities, engineering quality supervision of the station and other departments of the ideal testing equipment.Function and characteristic1) Using high-precision, all-digital speed control system and precision reducer, drive precision screw to test, to achieve a wide range of test speed adjustment, the test process of low noise, smooth operation.2) touch key mode of operation, real-time display of liquid crystal display. The display interface can display the test method selection interface, the test parameter selection interface, the test operation and the result display interface and the curve display interface, convenient and quick.3) can be achieved when the specimen clamping fast and slow beam adjustment, with overload protection and other functions.4) optional computer interface, an external computer to achieve the control of the test process and data storage, printing.
