Spring tension testing machine can also become spring tension and compression testing machine and spring testing machine. The spring tension test function can test and analyze the tension, pressure, displacement, stiffness and other strength of precision springs such as tension spring, compression spring, disc spring, tower spring, leaf spring, snap spring, leaf spring, composite spring, gas spring, die spring and special-shaped spring. Today, Xiaobian will take you to understand the relevant knowledge of spring tension and compression testing machine!

Classification and characteristics of spring tension and compression testing machine

1、 Manual spring testing machine

1. The load measurement adopts digital display, which overcomes the reading error of human eyes. The spring testing machine removes the displacement caused by the deformation of the load sensor and makes the displacement accurate. It has the characteristics of convenient use, high efficiency, high precision and stable performance.

2. Test force display: nixie tube digital display, with upper and lower limit sorting function, and output force value through sensor.

3. Displacement display: displacement grating ruler outputs displacement; The accuracy is 0.01mm.

4. Loading mode: manual loading, fast and convenient, displacement has positioning device, which is convenient for quick sorting.

5. Overload protection: software protection and mechanical protection. When the force value is overloaded, the controller makes a sound.

6. It is conducive to the batch inspection of spring production line; There are manual mode and automatic mode.

2、 Automatic spring tension and compression testing machine

1. High precision, full digital speed regulation system and precision reduction mechanism are adopted to drive the precision lead screw pair for test, so as to realize large-scale adjustment of test speed, low noise and stable operation in the test process

2. Touch operation mode, LCD real-time display, and the display interface can display the test method selection interface. It has four functions: positioning displacement measurement force value, constant deformation measurement force value, constant force measurement displacement and constant force measurement deformation, so as to realize all-round detection of spring measurement.

3. It can realize the fast and slow lifting adjustment of the beam during style clamping, and has overload protection function (software protection and mechanical protection). Overload is the automatic shutdown of the machine.

4. Realize the storage, analysis, printing and display of calculation data.

5. The repeatability error is very small; Suitable for sampling inspection.

6. The automatic machine has the functions of fast feed and slow acquisition; It can accurately collect the force value of displacement point.

3、 Microcomputer controlled spring tension and compression testing machine

1. Tensile test: conduct tensile test on various tensile springs; Compression test: conduct compression test on various compression springs.

2. Measurement method: measure the force value through deformation, measure the force value through height, measure the deformation through force value, and measure the height through force value.

3. Batch test: for samples with the same parameters, it can be completed successively after one setting; Batch inspection; There is no need to set parameters separately.

4. Test software: Chinese Windows interface, menu prompt, mouse operation.

5. Display mode: data and curve are displayed dynamically with the test process; Be able to observe the changes of the spring during the experiment; Compared with the first two processes, it is more intuitive.

6. Four kinds of curves: force value displacement curve, force value deformation curve, displacement time curve and deformation time curve.

7. Process realization: the test process, measurement, display and analysis are completed by microcomputer.

8. Automatic saving: after the test, the test data and curve will be saved automatically. In the later stage, the previous data can be queried without separate recording.

9. Test report: the report can be prepared and printed according to the format required by the user.

10. It is applicable to the sampling inspection of colleges and quality inspection departments.
