Computer Control Bolt-Nut Tension-Torsion Testing Machine
Introduction
The LNDW-2000 computer control bolt-nut tension-torsion testing machine is specially designed and assembled to conduct the test to verify the suitability of high strength bolt/nut/washer assemblies for pre-loaded bolted connection in metallic structures, as per BS EN 14399-2 and other relevant international test standards. It is an upgrading model from our NDW series computer control torsion testing machine, which is reliable and popular among our customers. The main system consists of loading part, driving part, digital data sampling and control system, and operating software. It can test the result of torque, torsion angel, axial force and other corresponding data and show torque – angel, force – angel , torque – force etc test curve.
Features
1.main structure
The main body of this machine adopts the floor-landing style, it is all made of high quality structural steel, which is of high stiffness and resistance ability to deformation and torsion. The motor, decelerator, coupler, dynamic torque sensor, and loadcell are all aligned well in the same center line, which makes the test result accurate and reliable.
2.loading structure
The loading structure is a re-new designed type upon the structure issued in EN 14399-2, as the following picture showing, when tightening the nut, it transfers the direct compression force on the loadcell to a load converter structure and compress the loadcell on the end side indirectly, in this way, it makes the testing bolt minimum length more short than before, thus making the test more flexible, and the samples more universal and accessable.
The dynamic torque sensor connects to the rotating side, when testing, the high torque servo motor drives the decelerator and dynamic torque sensor to twist the nut, with the certain hexagonal shape rigid grip. Every kind of bolt has a separate shape of jaws, for example, M12, M16, and M20. When twisting, only the nut rotates, the other parts can be strictly fixed. Moreover, the load convertor can move freely along the smooth rail, making it easy to adjust the test space.
3.the operating software
The whole test process can be conducted on the software, measuring, display, analysing, control and so on. When testing, the test data and curve can show in realtime, and the test result can be saved, inquired, analysed, compared, reported and printed. When the specimens are with the same information, only one time setting can fulfill a batch of test.
The software also equip with good security, it has the overload protection. When the test data exceeds 3%-10% of the full scale, the system will stop immediately to proctect the electronical and mechanical parts.
