Spectacle Spring Hinge (joint) Elasticity Test Machine China Supplier and Manufacturer
Spectacle Temple Torque Tester is intended to evaluate the changes in the elastic force of the eyeglass spring hinges by measuring the forces the spectacle temple can withstand at different angles.
It is an essential instrument to assess the performance of the sprung joints and the applicability of the spectacle temples.
Our spectacle temple torque test machine offers a workstation to hold the frame sample. The Clamping apparatus consists of a stationary fixture and a moving fixture. The fixed fixture can grip the lens next to the temple to be tested firmly with an adjustable screw. The moving fixture with a load cell is used to restrain the temple and guide it to bend under control. It can perform rotation in the range of 0 ~ 90 degrees or -90 ~ 0 degrees. The real-time torque value and rotation angle value are transferred to the control unit for analysis and display.
PLC controls the operation of this temple torque tester. It allows you to set a maximum torque and a desired bending angle of the temple on the touch screen. The single test will stop if either of the two conditions is achieved during operation. You need to reposition the movable clamp manually. In the “Auto Return” mode, you can customize the number of tests as needed. After every single test, the moving fixture will automatically return to the starting point for the next repeated test until all the set test times are completed. During the test process, the real-time torque value, peak value, bending angle, number of test times and test speed will be displayed on the screen for you to monitor.
