Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Horizontal computer-controlled spring torsion testing machine Introduction: Computer control spring torsion testing machine is mainly used torsion springs and elastic components of torque. Test parts are mounted between the clamps adjustable space to be tested can be adapted to different parts of the mechanical properties of the torsion test. Testing machine with computer-controlled operation of the spring, can be given angle torque test; the display shows the angle of the part being tested - the torque curve; real-time display angle, torque curve, torque peak hold, test machine working condition; test data storage, printing test report and so on. Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stampings business extension spring, the factory has advanced technology and equipment die springs, modern plant and professionals, products sold around the world. Spring steel is designed to manufacture all kinds of springs and elastic components or key performance requirements similar structural components. Common Table 12-10 for spring steel grades, performance characteristics and main uses of commonly used spring steel, its composition, heat treatment and mechanical properties may refer to relevant national standards (eg GB1222-1984). Table 12-10 spring steel grades used primarily performance characteristics and uses of the performance characteristics of the type of steel production should use ordinary carbon spring steel 65 Mn amount of hardness, strength, yield ratio, but poor hardenability, good heat resistance profiled spring, the ability to withstand dynamic loads and fatigue loads low low prices, and more used in the operating temperature is not high, a small spring <12mm or unimportant large amount of Mn 65Mn spring 7085 high hardenability, mechanical properties than steel However, lower prices more sensitive to overheating, the amount is large, the manufacture of various small section <15mm alloy spring steel flat spring, the spring, damper and spring clutch, brake shafts, etc. Si-Mn-based high 55Si2Mn strength, good flexibility, good resistance to tempering stability; but easy decarbonization and graphitization!
