In modern construction such as building engineering, bridges and tunnels, rail transit, and water conservancy facilities, steel bars and steel pipes are used as core structural materials, and their bending performance directly affects the safety and durability of the project. The forward and reverse bending test of threaded steel bars is a key means of testing the plasticity and toughness of steel, and is also a core requirement of national mandatory standards. Jinan Xinguang Testing Machine Manufacturing Co., Ltd.'s GW series steel bar bending testing machine provides high-precision and high-efficiency testing solutions for the production inspection, engineering acceptance, and quality supervision of construction steel.
The core of steel bar bending test is to accurately simulate the bending deformation ability of steel bars under construction and service conditions, and verify whether they meet the requirements of cracking and fracture resistance. The Xinguang GW series steel bar bending testing machine strictly follows the new national and industry standards for design and has the following outstanding advantages:
1、 Large diameter coverage, suitable for mainstream engineering needs
In response to the testing requirements of different specifications of steel bars, the Xinguang GW series can complete bending tests on steel bars and steel pipes with diameters ranging from 6 to 40mm, covering commonly used specifications in engineering and meeting the full range of testing needs from spiral steel bars to coarse diameter threaded steel bars. The equipment is also suitable for rigorous testing of high-strength hot-rolled ribbed steel bars.
2、 Accurate angle
Using a digital angle control system, the forward/reverse bending angle of the steel bar can be set arbitrarily within 0 ° -180 °. After setting the bending angle, it is automatically completed with high accuracy and good repeatability, completely eliminating human errors and ensuring accurate and reliable bending performance testing results for each batch of steel entering the site.
3、 Stable and reliable
Low work noise and clean environment.
4、 Intelligent limit and safety protection
Equipped with intelligent limit devices and overload protection systems, measures have been added to prevent equipment hazards caused by steel shavings and screw leaks while ensuring human-machine safety. The attachment structure is reasonable, the replacement of parts is simple, and the overall lifespan of the machine is long.
The Xinguang GW series steel bar bending testing machine complies with the following national standards and industry specifications:
-GB/T1499.2-2018 "Steel for reinforced concrete - Part 2: Hot rolled ribbed steel bars"
-GB/T232-2010 "Bending Test Method for Metallic Materials"
-GB/T5029-85 "Test Method for Reverse Bending of Steel Reinforcement in Plane"
-YB/T5126-2003 "Test Method for Bending and Reverse Bending of Reinforcing Steel Bars for Reinforced Concrete"
The product is widely used in the following fields:
-Construction Engineering Inspection Unit: Acceptance and Batch Sampling of Reinforcement Raw Materials on Construction Sites
-Steel production enterprises: Factory quality inspection of threaded steel and round steel
-Engineering Quality Supervision Agency: Circulation Supervision and Flight Inspection of Building Materials Market
-Research Institute: Development, Validation, and Performance Study of New Building Steel Materials
