Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

Metal wire bending machine is repeatedly according to GB/T238-2013 "metal material wire repeated bending test method is mainly used for the diameter or the feature sizes of 0.3-10 of the determination of metal wire repeated bending plastic deformation capacity.

After the plate clamping device is equipped, the bending test can also be carried out for the plate specimen.

This machine is widely used in steel, construction industry, wire rope, wire and cable, etc.

GB/ t238-2013 "method of repeated bending test of wire materials for metal materials"

1, principle: metal wire bending machine is repeatedly to fix one end of the metal wire, around the provision of cylindrical rod bending radius of 90 °, repeated bending test again along the opposite direction.

2, in order to ensure the continuous contact of sample in the cylinder rod, should impose some form of tensioning force, shall not be greater than the tension force test wire 2% of the nominal tensile strength of the corresponding power value, when a dispute, the tensioning force shall be equal to the test wire 2% of the nominal tensile strength of the corresponding value.

3. The number of bends should be carried out at no more than once per second without impact, and the test rate can be reduced to ensure that the heat produced during the bending process does not affect the test results.

4. Continuous bending test until the test number required in the relevant standard or until the sample bending fracture.The last bend of the sample fracture is not included in the number of bends.

5. Repeated bending test parameters:

1. Model: BJJWQ-10.

2. The diameter of the maximum bending wire is 0.3-10.

3. Bending Angle plus or minus 90.

4. Bending speed 60 times /min.

5. Counting range 9999.

6. Motor power (kW) 1.1.

7. Appearance: should comply with GB/T2611 requirements.

8. Completeness: meet the standard requirements.

9. Power supply: 220V, 50Hz.

10. The main frame size (mm) is about 800 * 600 * 1300.

11. Weight (kg) about 210.
