The spring tension and compression testing machine is made according to the technical requirements specified in JB/T7796-2005 Technical Conditions for Spring Tension and Compression Testing Machines.This machine is mainly used for tension and compression tests of various coil springs.The test force of the spring is measured under a certain displacement, or the deformation of the spring is measured under a certain test force. It can also be used for other elastic elements and small mechanical property tests, mainly used for spring manufacturers, low-voltage electrical appliances plants, power machinery plants, colleges and universities, and scientific research units.
Spring testing machineIt is a special instrument for testing springs.After the spring is produced, it can be put into use only after passing strict tests before use, because most of the springs are the main parts used on machinery and vehicles, such as the springs on vehicles. If the springs installed on vehicles have not passed strict tests, they can be installed on vehicles randomly, and the performance does not meet the requirements, which will easily lead to very serious consequences;Another example is the spring used for shock absorption. Because of the decline of performance, the vehicle loses balance and is prone to traffic accidents.This shows how important the spring test is.The function of the spring testing machine is also reflected.This machine is developed according to the technical requirements of the spring tension and compression testing machine standard.It is mainly used to test the mechanical properties and indexes of various spiral springs.
The dual speed preset can be realized by using the numerical control motor to load and control.It realizes high-speed approaching and slow acquisition, improves the test precision and ensures the test efficiency.It is designed with imported advanced large-scale circuit and controlled by computer.LED display, man-machine conversation is intuitive and clear.The mattress spring tester is an instrument used to evaluate the life of the springs in the mattress by testing the ability of the springs in the mattress to resist the load within a certain period of time.The loading device of the mattress spring testing machine consists of a pair of double hemisphere manually adjustable shaft heads and aThe weighing sensorThe force measuring impact head is composed.F-P, H-P, P-H and other modes are available for automatic test, and the return height can be set, and it will return automatically after the test is completed.It has 5 points of test, which can test printing stiffness, initial tension, etc.
