Horizontal computer-controlled spring torsion testing machine features: 1, suitable for Chinese test software WINDOWS platform, to achieve test data acquisition and processing. 2, wizard-based installation, user-friendly user interface. .3 Real-time collection of test data, the calculation processing, real-time display and print the results report. 3, the program has real-time control, data acquisition, automatic calibration, automatic archiving, rendering the measured curve, and artificial effective revision data, mathematical analysis 4, automatic generation of test reports and other functions, and define the report content according to user needs. 5, when tested, torque, torsion angle, and real-time torque - angle curve, with the testing process in real time. 6, can be set on the number of samples a continuous test, and the test set is stored in the computer. 7, using a graphical interface of Windows as operating system China Spring Factory, you can set the display screen and control panel. 8, the curve traverse 9, manual torque required at any time, angle measurement channel or automatically cleared. Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stampings corporate spring, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. With the scroll spring widely used in household appliances, sporting goods, security equipment, clocks and timers, to scroll Clockwork also put forward higher requirements. In order to eliminate the unfavorable residual stresses and improve the surface of the spiral winding of the stress distribution, advantageous to obtain a high stress, in addition to the measures taken in the selection of materials and the heat treatment, but in the manufacture of the spring is often used to strengthen the mechanical processes such as shot blasting processing, extreme pressure (pulling, twisting) treatment. Xufeng hardware products are based on the status of species and processing of materials to develop clockwork spring looking to experience can be summarized in three types I, hardened steel processing, such as carbon spring steel wire, piano wire, oil quenched and tempered II. hot forming and cold coil springs have been annealed material, should be subject to quenching. Third, after solution treatment and cold-drawn hardened austenitic stainless steel, precipitation hardened stainless steel, steel and copper nickel wire, steel and copper-nickel alloy material produced by cold forming process spring, after forming the need for age hardening deal with ..
