Numerical display steel bar reverse bending test device

Product Introduction

1Numerical display steel bar reverse bending test deviceIntroduction:

The reverse bending test device and fixture for steel bars are suitable for the "GB/T1499.2-2018 Steel for reinforced concrete Part 2: Hot rolled ribbed steel bars". It is a fixture with a simple structure, stable and reliable operation, and can provide accurate and sufficient bearing capacity for the reverse bending fulcrum.

IINumerical display steel bar reverse bending test deviceMethod:

The steel bar reverse bending test device and steel bar reverse bending test fixture are equipment for conducting plane forward and reverse bending tests on steel bars. The technical parameters and indicators of the equipment meet the requirements of the steel bar plane reverse bending method. This product is widely used in metallurgy, machinery manufacturing, construction industry, engineering supervision, technical quality supervision and other units to test the mechanical properties of various steel bars for forward and reverse bending. The clamping arm is connected to the steel reinforcement specimen by rotating the screw rod with a handwheel. The steel bar reverse bending test device is used in the process of steel bar plane reverse bending test. After the specimen is bent 90 ° in the forward direction, the reverse bending fulcrum is pushed by the oil cylinder piston to reach the maximum deformation zone where the steel bar can withstand forward bending, providing accurate and sufficient reverse bending fulcrum for reverse bending test. In order to overcome the practical problems encountered by the GW series steel bar bending test machine during the execution of the "reverse bending test: first bend 90 ° in the forward direction and then bend 20 ° in the reverse direction" specified in GB/T1499.2-2018 Steel for Reinforced Concrete Part 2: Hot Rolled Ribbed Steel Bars, such as insufficient reverse bending support points (especially for large-sized and high-grade steel bar specimens, the specimens will slide and cannot find the reverse bending support points to complete the test), difficulty in controlling the bending angle, inconvenient operation, safety hazards, and low work efficiency. Under the premise of meeting the standards, this device can provide accurate and sufficient reverse bending support points for different specifications of steel bars during reverse bending tests, without the need to reverse the specimen, reducing labor intensity and facilitating easy testing.

3、 Application characteristics of the reverse bending test device for steel bars:

The reverse bending test device for steel bars can provide sufficient load-bearing support points for different specifications and grades of steel bars during reverse bending tests, without the need to flip or adjust the position of the specimen to find the reverse bending support points. It is simple and reliable, and improves work efficiency and equipment utilization. The experiment proves that the device of this utility model is reliable and practical, effectively reduces the labor intensity of the tester, and meets the needs of steel bar bending and reverse bending tests.
