Key Features
1, The test machine is a four-pillar frame structure, the main cylinder is placed on, the main structure is composed of oil source, chassis, cylinder, piston, roller assembly, light bar, upper beam and other components.
2, The test machine uses highly sealed two-way cylinders, which are highly efficient and durable.
3, Test machine design in the aesthetic, convenient, safety aspects have been fully considered, for example: the main structure parts using ball-ink cast iron precision processing, the machine rigidity and good stability;
4, The branch roller spacing is adjusted by shaking the hand-lifting screw, and the spacing adjusts the rear roller self-locking without tightening, which is convenient to operate, which greatly reduces the labor intensity.
5, Bending head is the national standard GB/T232-2010 "metal material bending test method" designed for supporting products. This product is a special tool necessary for rebar bending test, and the replacement method is convenient for plug-in operation.
6, The one-in-one design of the forward and reverse bending device does not require repeated loading and unloading of the reverse bending device, which reduces the labor intensity and improves the efficiency, and the device conforms to the requirements of the reverse bending test in the standard GB1499.2-2018 Steel for Reinforced Concrete Part 2: Hot-rolled Rib Rebar.
7, Touch screen bending test control system, simple operation, small footprint, according to the test requirements to set the bending angle and automatically calculate the desired bending head diameter and roller spacing, manual and automatic dual mode selection, automatic mode can achieve the test process one-click operation (here is the control system legend).

Standard
ISO 7438 is a standard that specifies a method for determining the ability of metallic materials to undergo plastic deformation in bending. It is used to evaluate the flexural strength and stiffness of a material , The bend test shall be carried out in testing machines equipped with a bending device with two supports and a former; bending device with a V-block and a former; bending device with a clamp.
ASTM E290 Standard Test Methods for Bend Testing of Material for Ductility
ASTM E290 is a destructive mechanical test standard that evaluates the ductility and structural soundness of metallic materials (and welds) by subjecting specimens to controlled bending deformationASTM International. It is a widely used quality control and qualification method for metals, alloys, and welded joints across industries.
ASTM A1064 test standard covers steel wire and welded wire reinforcement produced from hot-rolled rod to be used for the reinforcement of concrete. The steel wire is cold-worked, drawn or rolled, plain (non-deformed, as-drawn or galvanized), or deformed. Welded wire reinforcement is made from plain or deformed wire, or a combination of plain and deformed wire. It specifies four mandatory tests for plain/deformed carbon-steel wire and welded wire reinforcement (WWR) for concrete: Tension Test, Bend Test, Reduction of Area Test, and Weld Shear Strength Test.
