Horizontal computer-controlled spring torsion testing machine Description: computer control spring torsion testing machine is mainly used for torsion springs and elastic components of torque. Test parts were installed between the clamps adjustable space can be adapted to different parts of the torsion test the mechanical properties of the test. Testing machine with computer-controlled operation shaped springs, can be given angle torque test; display being tested parts angle - torque curve; real-time display angle, torque curve and peak torque to maintain, test machine working condition; test data storage, printing test reports.

Disc spring is a spring washer material or forging blanks made of a truncated cone section of metal plates, can withstand axial load spring dish. Can be divided into non-bearing surface and there are two types of spring bearing surfaces, can be used individually, but also on the combined portfolio, combined into a composite combination or composite disc spring group uses tension springs to withstand a static load or variable load. Process spring dish: cutting - lathe - Deburring - stress relief - forming - heat treatment - extreme pressure - Shot - Surface treatment - test - dynamometer - packaging and storage . Most of the raw materials in accordance with strict strip thickness tolerances to produce strip with different thicknesses were used car parts, stamping, precision stamping, plasma arc / flame cutting, etc. processing. According to different applications, dish-shaped spring according to strict thickness tolerances using isothermal martensitic hardening or austempering heat treatment. Shot peening technology to improve the fatigue life of the spring plays a significant role. Preservative treatment process so that the spring dish improves corrosion levels.
