The bending test machine developed by Liang Gong is primarily used to test the bending properties of materials. Different test specimen materials require different equipment.
Currently, the bending testing machines provided by Lian Gong Detection are mainly categorized into:
GW-B Series Steel Reinforcement Bending Tester
The rebar bending tester is a specialized equipment used for cold bending tests and plane reverse bending tests on rebar. Its main technical parameters comply with GB/T 1499.2 "Steel tubes for reinforced concrete - Part 2: Hot-rolled ribbed rebar" and YB/T 5126 "Test plan for plane reverse bending of rebars" as well as the provisions and requirements for cold bending tests and plane reverse bending tests in ISO 10065. This equipment is an ideal testing device for steel mills and construction units to inspect the bending properties of rebars in both directions.
The rebar bending tester features a compact structure, simple operation, intuitive angle display, easy maintenance, smooth and safe operation, and low noise.
YWFS Series Hydraulic Bi-directional Steel Bar Bending Testing Machine
This product fully complies with the requirements of relevant standards, including "GB 1499.2 Reinforced Concrete Steel - Part 2: Hot-Rolled Ribbed Steel Bars," "YB/T 5126 Test Methods for Bending and Reverse Bending of Reinforced Concrete Steel," "GB/T 232 Test Methods for Bendability of Metallic Materials," "GB/T 244 Test Methods for Bendability of Metals," and "BS: 4449 Carbon Steel for Concrete."
If you have a purchasing need for this type of bending tester or any inquiries, please feel free to contact: 15689523180 or 400-623-6667.
YGBW SeriesHorizontal Rebar Bending Testing Machine
The horizontal bending tester for steel is used for bending tests on metal bars, tubes, plates, and threaded steel for construction, to determine their bending plasticity and bending ability. The tester complies with relevant standards such as GB/T 232 "Testing Methods for Metal Materials - Bending Test", GB/T 244 "Testing Methods for Metal Tubes - Bending Test", GB 13788 "Cold-rolled Ribbed Reinforcing Steel", and JC/T 446 "Concrete Paving Tiles". It is a commonly used equipment for material property inspection and research by metallurgical departments, scientific research institutions, quality inspection departments, and relevant enterprises.
The machine features a horizontal structure, with the hydraulic station integrated into the main unit. It is primarily composed of support rollers, bending cores, and press rolls. The main components include the main cylinder, hydraulic station, base, and electrical control system. The bending press rolls are adjusted synchronously by means of a manual dual-thread screw, allowing for the adjustment of the spacing between the support rollers. When a sample requires a 180° bend, the main cylinder can first push the bending core press roll for pre-bending, followed by the motor driving the side pressure plate to bend the sample to 180°. The operation is convenient and efficient.
2. GW-G Series Pipe Bending Testing Machine
The pipe bending tester is a specialized equipment for performing process bending tests on steel pipes. Its main technical parameters meet the requirements of the latest national standard GB/T 232 "Testing Methods for Metal Materials Bending" Article 7.3 regarding the test speed of (1±0.2) mm/s, allowing for real-time digital display of the bending angle corresponding to the displacement, facilitating users in completing tests at various bending angles. It complies with the testing requirements of GB/T 244 "Testing Methods for Metal Tube Bending", GB/T 3091 "Welded Steel Pipes for Low-pressure Fluid Transportation", GB/T 8162 " Seamless Steel Tubes for Structural Purposes", and GB/T 13793 "Straight Seam Electric Welded Steel Tubes".
The vertical three-point bending form of the steel pipe bending tester features stable structure, simple operation, easy replacement of the bend center, intuitive bending angle display, easy maintenance, smooth and safe operation, and low noise.
