Disc springs are widely used in heavy machinery, rail transportation, power equipment, aerospace, and engineering machinery due to their unique advantages such as high load-bearing capacity, strong buffering and energy absorption, and small space occupation. The performance of the disc spring is directly related to the safety and stability of the entire machine. As a pioneer in the field of material mechanics performance testing in China, Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") has officially launched a full series of microcomputer controlled disc spring pressure testing machines with mature technological accumulation, providing one-stop solutions from research and development testing to production quality control for disc spring manufacturing and use enterprises.
The force state of a disc spring is complex, and the detection requirements for its stiffness (K value), bearing capacity, displacement characteristics, and fatigue life are extremely high. The disc spring pressure testing machine launched by Xinguang strictly follows domestic and foreign standards such as JB/T7796 and JISB7738, and has the following core advantages:
1. Ultra high precision measurement system: The equipment adopts high-precision load sensors and imported photoelectric encoders, with a testing machine level of up to 0.5. The experimental resolution can reach ± 500000 yards, and the displacement resolution is ≤ 0.05 μ m, ensuring that both small precision disc springs and large load-bearing disc springs can obtain real and reliable stiffness curves and deformation data.
2. Full range load coverage: For different specifications of disc spring testing requirements, Xinguang can provide a variety of models ranging from 2kN small portal models to 600kN large portal structures. The equipment not only meets the pressure and compression stiffness testing of single disc springs, but also simulates the strong pressure treatment and permanent deformation analysis of composite disc springs under actual working conditions.
3. Intelligent measurement and high response: equipped with a fully digital closed-loop measurement and control system, supporting multiple control modes such as force, displacement, deformation, etc. With a sampling frequency of up to 500Hz, it can capture the subtle changes of the disc spring at the moment of loading in real time, accurately draw the force displacement curve, and automatically calculate the elastic coefficient and yield point.
4. Humanized software experience: The testing software independently developed by Xinguang has an intuitive interface and supports free switching between "fixed force measurement deformation" and "fixed deformation measurement force" dual modes. The experimental data can be automatically saved and directly generated into Word, Excel or PDF standard test reports, making it convenient for enterprises to trace quality and analyze R&D data.
At present, the Xin CD spring testing machine has been widely used in multiple key fields:
Production quality control: used for online sampling in batch production of disc springs, quickly screening for stiffness consistency to ensure stable elasticity of each piece of disc spring leaving the factory.
R&D analysis: Assist engineers in verifying the impact of new materials or heat treatment processes on the performance of disc springs and optimizing product structural design.
Type test: Cooperate with national quality inspection agencies to conduct strict network testing on key disc springs in power safety tools and high-speed rail damping systems.
Although the disc spring is small, its responsibility is significant. It often plays a buffering and protective role as the 'last line of defense' in equipment, "said the person in charge of Xinguang Technology." Our goal is to help users turn invisible 'stress' into visible' data 'through iterative testing technology, and safeguard industrial safety with accurate data
