1. Product overview:
Metal wire rod bending tester is also known as metal wire rod bending tester. It is mainly used for cold bending test and plane repeated bending test of metal wire rod, steel bar, thin plate and thin strip, so as to test its cold bending performance, that is, the performance of plastic deformation and defects in repeated bending, which conforms to GB / T 238-2002 "metallic materials and wires" Methods of repeated bending test. Metal wire rod repeated bending testing machine is widely used in wire and cable, steel wire factory, prestressed steel wire factory, building materials, highway transportation, factories and mines, scientific research institutes, quality inspection units to inspect the bending properties of steel wire, steel bar and other metal wires.
Test principle: the sample of a certain specification is clamped in two jaw of specified size through the guide sleeve. Press the button to bend the sample at 90 ° left and right. After the sample breaks, the machine stops automatically and the bending times are recorded.
Applicable standards:
1) GB / T 238-2013 metallic materials wire rod test method for repeated bending
2) GB / t4909.5-2009 "test methods for bare wires - Part 5: bending test - repeated bending"
3) TB / t2809-2005 copper and copper alloy contact wire for electrified railway
4) GB / t235-2013 metallic materials sheet and strip with thickness equal to or less than 3 mm
2、 Metal wire rod bending tester Performance features:
1) The bending test of various materials can be done by changing the clamping jaw of different specifications;
2) One key operation, automatic shutdown and one key reset;
3) Large LCD displays bending times;
4) Stable performance, compact structure, reliable quality, suitable for long-time work;
5) Small material, with automatic tension device;
6) The test speed is stepless adjustable;
7) The operation is simple, and the number of bending is displayed;
8) By adding appropriate device, it is possible to achieve Φ 0.3 - Φ 3 mm, and repeated bending test of plate can also be done.
