1. Product use
This machine is an important instrument and equipment for testing the physical properties, mechanical properties, technological properties, structural properties and internal and external defects of various materials and their products. It can realize tensile, compression, bending, shear and other types of tests on metallic or non-metallic materials, and can automatically obtain the tensile strength, yield strength, specified non-proportional elongation strength, elastic modulus and other performance indicators of the measured materials. Closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain can be completed.
This machine is accurate in testing, powerful in function, easy to operate, stable and reliable. It is widely used in universities, scientific research institutes, testing institutions, aerospace, military industry, metallurgy, machinery manufacturing, transportation construction, construction and building materials and other industries for precision material research, material analysis, material development and quality control. Process qualification performance verification tests of materials or products can be performed.
2. Technological innovation
• New external independent controller---adding an independent external manual control unit provides a new solution for the measurement, control and operation of the testing machine. USB data transmission fully supports notebook computers, tablet computers and desktop computers; It is an important part of leading the development of testing machine technology;
• Multifunctional handheld controller---can control the rise and fall of the moving beam and oil cylinder, the clamping and loosening of the jaws, and also has the emergency stop function of the oil pump, making it more convenient to use sample clamping;
• Equipment operation monitoring system---it has phase sequence, phase loss self-check indication functions, electrical overcurrent, overload and other protection functions, making the equipment operation safe and reliable;
• The upper and lower jaw seats of the main machine adopt a built-in clamping method---the sample clamping is more stable and the sample fracture alignment is better;
• An elastic shock absorption mechanism is installed at the lower part of the lead screw---effectively reduces the impact caused by sample fracture and reduces noise;
• Add a flexible dust cover outside the lead screw to prevent foreign objects from entering, increase the durability of the lead screw and transmission mechanism, and improve the aesthetics of the whole machine;
• Safety protective cover---Three-sided cold-rolled steel plate punched safety protective cover prevents foreign objects from flying out during the test. It not only improves the protection level, but also facilitates real-time observation by operators, effectively ensuring the personal safety of experimenters.
• The servo pump station adopts cartridge valve pressure differential follow-up technology-energy-saving, environmentally friendly, safe and reliable, and reduces system heat; At the same time, the clamping force increases with the increase of the test force, and the sample clamps firmly.

• Foundation production: The foundation is shown in the figure below. When planning the installation location of the equipment, the convenience of maintenance and inspection should be fully considered; It is recommended that a space of 500-800mm away from obstacles be reserved behind the equipment and on the left and right sides; An operating space of not less than 2000mm must be maintained directly in front of the equipment; When the thickness of the original concrete foundation at the installation position is more than 150mm, rhinestone can be used to drill holes according to the size of the foundation drawing; If the foundation thickness is less than 150mm, please install and construct according to the drawing;
