Portable steel bar bending machines do have different bending effects on steel bars of different materials (such as ordinary steel bars, high-strength steel bars, etc.), which is mainly due to the different physical and chemical properties of steel bars of different materials, such as yield strength, elongation, hardness.
Bending effect difference
Ordinary steel bars: The yield strength and hardness of ordinary steel bars are relatively low, so it is relatively easy to achieve the required bending angle and shape when using a portable steel bar bending machine for bending. In addition, the elongation of ordinary steel bars is moderate, making it less likely for the steel bars to crack or break after bending.
High-strength steel bars: The yield strength and hardness of high-strength steel bars are higher, which means that more force is required to achieve the required bending angle during the bending process. At the same time, the elongation of high-strength steel bars may be lower, increasing the risk of cracks or breaks after bending.
Parameter adjustment suggestions
In order to adapt to the bending needs of steel bars of different materials, the following parameters of the portable steel bar bending machine can be adjusted:
Bending angle: Set the required bending angle through the control panel or manual adjustment device according to the specific project requirements. For high-strength steel bars, it may be necessary to control the bending angle more accurately to avoid cracks or breaks caused by excessive bending.
Bending speed: Reducing the bending speed can reduce the heat and stress generated during the bending process, thereby reducing the risk of cracks in high-strength steel bars. For ordinary steel bars, the bending speed can be appropriately increased to improve work efficiency.
Pressure adjustment: Portable steel bar bending machines are usually equipped with a pressure adjustment device to control the force applied to the steel bars during the bending process. For high-strength steel bars, the pressure needs to be increased to ensure that the steel bars can be bent smoothly; for ordinary steel bars, the pressure can be appropriately reduced to avoid excessive bending.
Mold selection: Steel bars of different diameters and shapes require different molds for bending. Therefore, when selecting a mold, it should be selected according to the material and diameter of the steel bar to ensure the bending effect and safety.
Precautions
Before using a portable steel bar bending machine for bending, the steel bars should be inspected and pre-treated as necessary, such as removing rust and oil stains, to ensure the bending effect and safety.
During the bending process, pay close attention to the bending condition of the steel bars and the operating status of the machine. If any abnormality is found, the machine should be stopped in time for inspection and troubleshooting.
Regularly maintain and service the portable steel bar bending machine, such as cleaning the mold and checking the electrical system, to ensure its normal operation and extend its service life.
