Steel bar bending machine is to plane is reinforced, reverse bend test special equipment. The equipment main technical parameters and indexes accord with YB/T5126-2003 "reinforced concrete with steel bending and reverse bending test method". The products are widely used in steel mills and construction units, to test rebar is, reverse bending performance.

Bjjwq-40 steel bar bending test machine, in the limit of safety. The replacement of vulnerable parts. The extension of the life of the whole machine has been greatly improved, which is a relatively complete bending test machine.

YB/ t5126-2003 "bending and reverse bending test method for reinforced concrete"

Principle:

Bending test is to sample two arms or an arm strength, make the samples on the regulation of the diameter of the bend (heart) of curved arc surface, under a bending moment and produce around the circular arc surface plastic deformation test to a specific Angle.The aging performance is tested by reverse bending test, including bending test and aging heat treatment, and reverse bending of the sample to a certain Angle.

Test steps:

Bend test

1. The sample is bent at the curved surface (bending the heart), and the Angle of bending and bending of the arc surface (bent) diameter D should meet the requirements of the relevant product standards.

2. The bending speed should be not more than 20 ° / s, can be based on the Angle indicator indicated Angle to observe, to speed down to accurately control the bending Angle, can also through the Angle of setting and display instrument to automatically control the bending Angle.After the completion of the test, the sample should be carefully observed. If no visible crack is visible, the test will be qualified.

Reverse bending test.

1. The specimen should be bent around the curved surface (bending the heart). The Angle of bending and the diameter of the curved surface (bent) should meet the requirements of the relevant product standards.The test should be conducted at room temperature of 10 -35.

2. After bending specimen should be aging heat treatment at 100 ℃ temperature, holding time at least 30 min, free after cooling to room temperature in air, reverse bend test.According to the relevant product standard or the agreement between the supply and demand parties, the bending test samples are not subjected to aging heat treatment and the reverse bending test is conducted directly at room temperature.

3. The reverse bending speed should be not more than 20 ° / s.The test equipment should be able to shut down accurately when the reverse bending to the specified Angle.After the completion of the test, the sample should be carefully observed. If no visible crack is visible, the test will be qualified.

The characteristics of

1. Bending and reverse bending Angle within 0-180 ° set arbitrary;

2. The bending Angle is displayed in real time.

3. Safe and reliable intelligent limit.
