JWJ-13 Metal Wire Repeated Bending Testing Machine

1. Main Purpose and Application Range

This testing machine is designed by our company in strict accordance with GB/T238-2013 "Metallic materials wire reverse bend test method", ISO 7801:1984 "Metallic materials Wire Reverse bend test", GB/T21839-2019 "Prestressed concrete steel test method", ISO 15630-3:2010, "Steel for the reinforcement and prestressing of concrete-Test methods-Part 3; Prestressing steel, MOD". It is mainly used for repeated bending tests of metal wires to test the performance of metal wires in plastic deformation and defects in repeated bending. It meets the requirements of applying a certain tension force to the specimen during arbitration tests. This machine is widely used in the steel and construction industries, as well as the production of wire ropes, wires and cables.

Standard:

ISO 7801:1984 Metallic Materials – Wire – Reverse Bend Test

ISO 15630-3:2010 Steel for the Reinforcement and Prestressing of Concrete – Test Methods – Part 3: Prestressing Steel

GB/T 238-2013 Metallic Materials – Wire – Reverse Bend Test Method

GB/T 21839-2019 Prestressed Concrete Steel – Test Method

Advantages:

1. Curved Design: The machine features an aesthetically pleasing and high-end curved appearance.

2. LCD Touchscreen: It utilizes an LCD touchscreen operating system, replacing outdated button panels, making operation more convenient and extending the lifespan of the system by 5 to 6 times.

3. Servo Motor and Worm Gear Reducer: The machine combines a servo motor with a worm gear reducer to provide adjustable test speeds with smooth, noise-free operation.

4. Weight Hanging Plate: The addition of a weight hanging plate allows for the application of standard tightening forces on the sample, addressing the limitation of similar devices from other manufacturers that cannot apply precise tightening forces in critical arbitration tests. This technology has been patented as a new invention in China.
