抗彎強度試驗機，拉壓彎試驗機，微機控制數顯試驗機

Main use

The machine for metal, nonmetal and composite materials mechanical properties test and analysis, is widely used in aerospace, petrochemical, machinery manufacturing, plastics, rubber, ceramic building materials, metal materials, construction and other industries, and institutions of higher learning, scientific research institutions, technical supervision, ZhiJianZhan departments and so on.

According to GB/ISO/ASTM, JIS, DIN standard, such as matching different affix can be carried out after tensile, compression, bending, peel, cut, torn, punctured, bursting, detects the material yield strength, tensile, compression, bending） strength, elongation, parameters such as unconstrained strength, modulus of elasticity.

Control system software based on WINDOWS operating system as a platform, with fast, moderate interface, simple operation etc., to meet the needs of the measured results of different materials. If you have special requirements, the software can be customized, and can extend software functions according to the requirements of customers.

Measuring system:

Load measurement: using 0.05% FS sensors, high stability, high precision and spokes tension and compression with high performance measurement amplifier system, to ensure the test force of the high resolution.

Sample deformation measurements: large deformation measurement system or electronic extended meter （small deformation measurement）, collection system controlled with 24 bits A/D conversion, data processing by computer control, realize the sample deformation measurement.

Displacement measurement: adopt high precision photoelectric encoder and 2000 p/R precision leadscrew coaxial rotation, through the digital circuit implementation measure displacement （that is, the upper and lower clamp relative displacement） measurement.

Drive control system

This machine adopts double space gantry structure, spatial tensile, compression, bending under space. Host part of the column, beam, the beam, the workbench of the gantry framework, speed control system installed at the bottom of the workbench, by high speed control precision, wide range, stable performance of the servo motor through the synchronous toothed belt drive the ball screw vice deceleration system, beam in the ball screw pair drive, drive the tensile stogether stogether （or compression, bend） to move up and down, sample loading and unloading. This structure has the advantages of high rigidity, high efficiency, stable transmission.

The test force control system

Computer combined with the use of advanced electronic technology, standardization, unitary control, has the stable load, accurate measurement, high acquisition frequency, etc. A variety of automatic test data collection and processing, draw curve and print the test report.

Protection device

Overload, over current and leakage protection function.
