Product Description
This testing machine is mainly used for the reverse bending test of metal wire, thin plate and thin strip, in order to check the performance of metal materials to withstand plastic deformation and obvious defects in reverse bending.
Testing principle: the sample of certain specification is clamped in two jaw of specified size through the guide sleeve, and the machine is started. The sample is bent at 90° left and right. After the sample breaks, the machine stops automatically and the bending times are recorded.
Applicable standards
GB/T 238-2013 “Metallic materials wire rod bending test method”
GB/T4909.5-2009 “Test methods for bare wires Part 5: Bending test - Reverse bending”
TB/T2809-2005 “Copper and copper alloy contact wire for electrified railway”
GB/T235-2013 “Test method for reverse bending of sheet and strip of metallic materials with thickness equal to or less than 3 mm”
Features
1. Replacing clamping jaws with different specifications allows for bending tests of various specifications of materials;
2. PLC programming, frequency converter control motor, touch screen operation, and adjustable bending speed.
3. Stable performance, compact structure, reliable quality, suitable for long-term work;
4. Quick tensioning device, easy to operate
