拉壓彎試驗機，抗彎強度試驗機

WDW - S digital display type electronic universal testing machine （single arm type）

Main use

The machine for various metals, non-metallic and composite material mechanics performance testing and analysis, is widely applied in, petrochemical industry, 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 and various high and low temperature test, to test the material yield strength, tensile, compression, bending） strength, elongation and other parameters.

Host structure

This machine adopts single arm type structure, the host part by in the beams, columns, beams, workbench, 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 cog belt deceleration system drives the ball screw vice rotation, beam in the ball screw pair drive, drive stogether tensile 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.

Comprehensive test platform

Miniature computer hardware platform, accurate real-time data collection and processing, and control interface is mild, the intuitive distinct and clear, simple operation, etc.

Test force measurements:

Load measurement: choose high precision hub-and-spoke load sensor, amplifier system with high performance measurement, to ensure the high resolution of the test force. Can configure multiple sensors based on user demand, realize the wide range of measurement test force.

High precision displacement measurement: use 2000 p/R photoelectric encoder and precision screw coaxial rotation, to measure a dynamic control system was achieved by digital circuits

Is controlled by digital servo controller, high performance servo motor driven synchronous cog belt, drive the two pairs of high precision without clearance of precision lead screw transmission, are characterized by their smooth load, low speed performance is good, no gap, high transmission efficiency, low noise, stable transmission characteristics.

Deformation measurement system

Can be equipped with large deformation, according to the requirement of test standard measurement system

Protection device

According to the different test, adjustable limit protection switch position, the most effective to prevent the fixture collisions.

Overload, over current and leakage protection function.
