WDW-E series of computer-controlled electronic universal testing machine (aluminum housing) WDW-E series of computer-controlled electronic universal testing machine (aluminum housing) The main purpose of this machine can perform mechanical testing and analysis of the performance of metals, non-metallic and composite materials widely used in aerospace, petrochemical, machinery manufacturing, plastics, rubber, ceramic materials, metal materials, construction and other industries, as well as universities, research institutions, technical supervision, inspection stations and other departments. Can be drawn according to GB / ISO / ASTM / JIS / DIN standards, compression, bending, shear, and a variety of high and low temperature test can detect the material yield strength, tensile strength (pressure, bending) strength, elongation, non- proportion of strength, elastic modulus and other parameters. The machine uses dual host structure floor-space structure, the space stretching space under compression, bending. Host part consists of four columns, on the beam, the beam, floor-to-table composition framework, speed control system installed in the lower part of the table, by the speed and high precision, wide range, stable performance of Panasonic AC servo motor by synchronizing toothed belt deceleration system driven ball screw rotates, the ball screw drive beam, driving accompanied by stretching (or compression, bending accompanied) moves up and down to achieve the loading and unloading of the specimen. This structure has a high stiffness, high efficiency, driving stability. Host main components in the processing center for processing, to ensure the accuracy of the host. Accompanied by the standard configuration wedge tensile, compression accompanied by bending accompanied each set of test platform this machine brand computer as the hardware platform, the use of computer PCI (using Plug and Play technology PNP) slot machine and test acquisition and control system is connected directly to tell, accurate, real-time data acquisition and processing, monitoring and control software for WINDOWS operating system as the platform, moderate interface, intuitive, structured, easy to operate. Monitoring and control software can meet the test to test different materials. According to relevant international standards, the physical properties of mechanical testing of national standards or industry standards to test a variety of materials, the user can output the desired report. Test force measurement: load measurement: 0.02% FS using high stability, high precision imported spoke load sensors, together with the high performance measurement amplification system to ensure high-resolution test force. Multiple sensors can be configured according to user needs, to achieve a wide range of test force measurements. Specimen deformation measurements: 24-bit A / D converter MCU acquisition systems, computer data processing, deformation measurement sample. Displacement measurement: The 2000P / R imported high-precision optical encoder with precision coaxial rotary screw, through digital circuits after doubling down plastic chuck relative displacement measurements. Test force control system adopts imported digital AC servo controller to control the performance of AC servo motor drive timing belt, driven by two pairs of high precision seamless precision screw drive. With a steady load, low-speed performance, no gap, high transmission efficiency, low noise, smooth drive and so on. Ease of operation on an external host controller for each specific six buttons on the fast, fast down, slow, slow down, start, cleared. Protection devices, depending on the location of the trial, you can adjust the position of the limit switch, effectively preventing the collision fixture. Overload, overcurrent, leakage and other protection.
