The touch screen fully automatic spring tension and compression tester is made according to the technical requirements specified in JB/T7796-2005 Technical Conditions for Spring Tension and Compression Tester, and is specially set for spring detection. It is mainly used to test the strength of various springs and elastic elements, that is, to test the test force of springs under a certain amount of deformation (or residual height). The testing machine adopts frequency conversion and speed regulation technology, achieving high-speed approximation and low-speed acquisition, ensuring testing efficiency and improving accuracy. It has the functions of test force value display, speed setting, and limit protection and overload protection.

Product Overview
The touch screen fully automatic spring tension and compression tester is made according to the technical requirements specified in JB/T7796-2005 Technical Conditions for Spring Tension and Compression Tester, and is specially set for spring detection. It is mainly used to test the strength of various springs and elastic elements, that is, to test the test force of springs under a certain amount of deformation (or residual height). The testing machine adopts frequency conversion and speed regulation technology, achieving high-speed approximation and low-speed acquisition, ensuring testing efficiency and improving accuracy. It has the functions of test force value display, speed setting, and limit protection and overload protection.

Main features
1.Main engine: adopt double-arm structure. The rigidity and strength of the main engine frame are fully guaranteed through mechanical finite element analysis. The transmission system adopts a zero-gap ball screw pair to ensure the accuracy and durability of the test results. The main frame is guided by four lead screw columns to ensure the rigidity of the frame.
2.Transmission system: Driven by a motor, it is directly transmitted to the ball screw through a synchronous toothed belt, driving the middle beam to move horizontally up and down.
3.Drive system: drive the system by driver and stepper motor.
4.Measurement control system: the test force measurement display system is composed of high-precision load sensor, measurement amplifier, A/D conversion, LCD touch screen, etc; The displacement measurement and display system is composed of photoelectric encoder, frequency doubling and shaping circuit, counting circuit, etc; Touch screen display, human-computer dialogue is intuitive and easy to operate.
5.It has the function of judging whether the target force value of the spring is qualified or not. Before the test, input the upper and lower error range of the target force value. After the test is completed, the system will automatically judge whether it is qualified or not, and display with an indicator light. The green light on the qualified display is on, and the red light on the contrary. For example, when measuring multiple points, the screen will display which point is unqualified.
6.Test start button can not only start the test on the touch screen, but also add physical test button to make the control mode more convenient.
7.Control mode: various control modes such as test speed and displacement can be realized. The main functions are as follows:
8.Input the remaining height of the spring and measure its corresponding test force value. Up to 10 points can be measured
9.Input the deformation of the spring and measure its corresponding test force value. Up to 10 points can be measured
10.Print the parameters and stiffness of each test point.
11.It has the function of automatic paralleling to eliminate errors and errors caused by manual paralleling and make the experimental operation safer.
12. Safety protection device: overload protection, beam limit position protection, overcurrent, overvoltage, overspeed protection, etc.
