Microcomputer controlled spring tension and compression testing machine (portal type)

The microcomputer-controlled spring tension and compression testing machine is made according to the technical requirements stipulated in JB/T7796-2005 "Technical Conditions for Spring Tension and Compression Testing Machines" and is specially designed for the testing of springs.It is mainly used to test the strength of various springs and elastic components, that is, to test the test force of the spring under a certain deformation (or remaining height) or to measure the remaining height or deformation of the spring under a certain test force.It has functions such as test force value display, speed setting, batch test setting, etc. At the same time, it also has functions such as limit protection and overload protection.

Different test plans can be established according to needs. Multiple batch numbers can be established under one plan to conduct batch tests. During the test process, data are collected in real time and curves are drawn in real time. Access large database is used for data storage, which facilitates user resource sharing and re-analysis.After the test is completed, the data is automatically processed and saved. The test results can be viewed at any time and the test report can be printed. The test report format can be changed according to the different requirements of the user.The testing machine's processing of test data fully complies with the standards of spring testing machines.

Control method: A variety of control methods are adopted, the specific descriptions are as follows:

a) Set the test force P and detect the deformation F of the spring.

b) Set the deformation amount F and detect the test force P of the spring.

c) Set the test force P and detect the remaining height H of the spring;

d) Set the remaining height H of the spring and detect the test force P of the spring;

Ten detection points can be set.The spring can be pre-compressed to a set pre-compression height, and the number of pre-compression times can be set at will.

Batch testing is very convenient for users. After setting the number of tests, the testing machine will automatically test according to the set number of times without manual intervention.

During the test process, high-speed approximation and low-speed acquisition are achieved, ensuring the efficiency and accuracy of data collection on the testing machine.

Set the test speed by yourself and automatically return to the initial position after the test is completed.

With overload automatic shutdown function.

It is equipped with a manual micro-feeding device, which can realize micro-feeding under various load conditions and facilitate calibration and displacement fine-tuning.

For spring testing, the segmented stiffness P of the compression spring can be automatically calculated.^/.The calculation formula is as follows: spring stiffness P^/=(P₂—P₁)/(F₂—F₁)
