WDW-10E/20E microcomputer control electronic universal testing machine

WDW-10E/20E microcomputer control electronic universal testing machine

Features :

Complete computer controlled : The whole measuring and controlling system adopts specific PC control card used for testing machines, raelizing the data zero and plus adjustment, which has very high reliability.

 

Supporting multi-transducers

 

Realizing the database management of the test data which are stored according to the standard format; facilitating other software to analyze and transfer.

Perfecr programming by auto program control, every control mode can smoothly shit to another one. Fulfilling the test requirement of all kinds of materials with every test standard home and abroad.

 

Control software has the auto-adjusting function of test hardness, which assures that the system work with every kind of specimen hardness.

Perfect graphic function realizing the arbitrarily magnifying, decreasing, aqualiing, adding, indicative display and print of all kids of test curves, the test point searching as weell as the simultaneous display and print of saveral kids of test curves. Data processing supposes self-disposing and input disposing of graphic human computer interaction, which facilitates the check and contrast of the last result.

The user can self-define the output of the report, which makes the report format have very high flexibility.

 

Modlarization design facilitates the software upgrading, function spreading as well as the second development.

 

 

 

1. Applicable test method standards

 

GB/T228 "Metal material tensile test method at room temperature"

GB/T7314 "Metal material room temperature compression test method"

Can meet GB, ISO, ASTM, DIN and other standards. Other corresponding standards can be added according to customer needs.

 

2, product introduction

 

The machine is mainly used for tensile, compression, bending and other conventional performance tests of metal and non-metal materials, and measures performance parameters such as R P , R t , R eH , R eL , R m , E and so on. Equipped with corresponding accessories, it can also be tested according to GB/T5027 and GB/T5028 metal sheet plastic strain ratio (r value) and hardening index (n value); according to GB/T4338 high temperature tensile test.

 

The mainframe adopts a desktop single space, and the frame structure is a double-column double-threaded door structure. The speed control system is installed in the lower part of the workbench , and the lower space is used for stretching, compression, bending and shearing tests (the test space can be customized into double spaces according to customer requirements). The beam is steplessly raised and lowered. The transmission part adopts arc synchronous toothed belt and screw drive, which has stable transmission and low noise. The specially designed synchronous toothed belt reduction system and the precision ball screw pair drive the moving beam movement of the test machine to achieve a gapless transmission. Adopting imported AC servo drive and AC servo motor, the performance is stable and reliable, with protection devices such as overcurrent, overvoltage, overspeed and overload.
