FF-10 Prestressed Steel Repeated Bending Testing Machine

Description

Main uses and scope of application:

This testing machine is primarily used for repeated bending tests of metallic wires, to evaluate their ability to withstand plastic deformation under cyclic bending and to detect any defects that may arise.

Test principle: A specimen of specified diameter is passed through a guide sleeve and clamped between two jaws of prescribed dimensions. After adjusting the guide sleeve height, the button is pressed to induce a 90° left–right bending cycle. Upon fracture, the machine automatically stops and records the number of bending cycles.

This machine is widely used by manufacturers in the steel and construction industries, as well as by producers of reinforcing steel bars, prestressing wires, wire ropes, electric wires and cables, copper and copper‑alloy contact wires, conductors, and other related products.

Suitable for metal wires with diameters ranging from Φ0.3 to Φ10; equipped with a special fixture, it can also perform bending tests on metal wires with diameters from Φ1 to Φ10.

Applicable Standard:

GB 238-2002 “Metallic Materials — Wire — Method for Repeated Bending Test”

TB/T 2809-2005 “Copper and Copper Alloy Contact Wires for Electrified Railways”

TB/T 3111-2005 “Copper and Copper Alloy Conductors for Electrified Railways”

GB/T 4909.5-2009 “Test Methods for Bare Wires — Part 5: Bending Test — Repeated Bending”

Technical Specifications:

Specimen diameter: Φ0.3–Φ10 mm
