Multichannel controlled spring tension and compression testing machine

This machine is mainly used to test the mechanical properties of various springs and gas springs. The control software can automatically calculate the technical indicators and conventional data required by the spring, automatically calculate the data results of force, stress,displacement and deformation of any specified point in the test process,and also measure the load,elastic coefficient,free height and other parameters of the spring at the specified height.

Detailed

Model：JB
　　This machine is mainly used to test the mechanical properties of various springs and gas springs. The control software can automatically calculate the technical indicators and conventional data required by the spring, automatically calculate the data results of force, stress,displacement and deformation of any specified point in the test process,and also measure the load,elastic coefficient,free height and other parameters of the spring at the specified height.

三、Function introduction：
. Measurement method: At the same time, it has automatic and inching (Button to move up and down) measurement;lt can be measured step by step (When the load is measured automatically, the beam will drop directly from the preset height to the height required to be detected 1,2 and 3,and thenautomatically return to the preset height to measure the load of different springs in a cycle, and only the load that needs to be detected is displayed) ;
. Automatic returm function: height and load can return to zero automatically (the pressing plate surface below the height is the zero point, and the automatic return to zero);
. It can automatically measure the load of spring with different residual height,the elastic coefficient between two spring heights,and the height of spring winding. lt can manually measure the load and winding height of any remaining height of spring, and can manually drop to any specified height to stop.
. When measuring the spring automatically, input the measuring condition (residual height of spring) and judgment value, and then measure it . After measuring, the system can automatically judge whether it is qualified or not.
