Metal Wire Repeated Bending Tester

Meet the standard

GB/T 238-2013 "Metal material wire repeated bending test method"

GB/T 235 "Metal material thickness is less than or equal to 3mm sheet and thin strip repeated test method"

ISO/DIS 7801-1983 "Repeated bending test of metal wire"

Main uses

Metal wire repeated bending tester used for repeated bending test of wire, for different specifications of wire bending radius can be replaced with different round rod, bending position (height) can be adjusted, perforation diameter to replace different bushings.

Test principle

The sample of a certain diameter is clamped in two round rods of specified size, press the button, the sample is bent at about 90°, the sample is broken, and the bending number is automatically stopped, and the bending number is recorded to test the performance of the metal wire under plastic deformation and the defects displayed during repeated bending.

Product Advantages

Evaluates Bending Fatigue: Directly assesses the wire's resistance to repeated bending stress.

Quantifies Ductility: Provides a numerical value (number of bends to failure) for wire ductility under dynamic bending.

Detects Defects: Repeated bending can reveal hidden surface or internal defects that may lead to premature failure.

Standardized Testing: Enables testing according to established national and international standards.

Controlled Test Parameters: Ensures repeatable and comparable test results through precise control of bending angle, speed, and radius.

Automated Operation: Automatic stopping upon fracture and cycle counting simplify the testing process.

Versatile: Can test a range of wire diameters and allows for adjustment of test parameters.
