Application:
Wire torsion testing machine applies to determine the ability of diameter(or feature size) of 0.1-20.0 mm wire for bearing plastic deformation in one way or two way torsion test, display the surface and internal defects of the wire. Provide reliable data for production of wire and wire rod company. Widely used in aerospace, metal material processing, tire manufacturing industries, and institutions of higher learning, scientific research institutions, technical supervision, quality inspection departments and so on.
Standard: Wire torsion testing machine
GB/T2611-2007 General requirements for testing machines
GB/T 239-1999 Metal wire twisting test method
ISO 7800:1984 Metal wire one-way torsion test method
ISO 9649:1990 Metal wire two-way torsion test method
Could add special gips to do the wrap winding testing machine.(optional)
Features:
1) One way torsion :Sample around its own axis in one direction evenly rotate 360 ° as a torsion,
until to the stipulate times or sample breakage.
2) Two way torsion:Sample around its own axis in one direction evenly rotate 360 °
as a torsion, until after to the stipulate times,then rotate same times in opposite direction or sample breakage.
3) Number setting:Automatic stop when reach the presetting torsion number;
4) Rotation speed adjustable:Adopting adjustable- speed motor knob switch,
5) Display mode:Digital real time display
