Pipe bending is a metal processing process that bends pipes into various shapes to meet different purposes. This process is widely used in the field of metal fabrication. Tubes formed by the tube bending process are not limited to any particular metal, but are suitable for different materials, including most metals and alloys.
When it comes to pipe bending, there is no set method, but many different options to achieve the pipe bending effect. Each method has its own unique advantages, disadvantages and prices.
One of the common methods of pipe bending is by using a pipe bender. The pipe bender is capable of precise bending of pipes and is suitable for mass production. Another method is manual pipe bending, which bends pipes by hand, which is suitable for processing needs of small batches and special shapes. There are also some advanced pipe bending techniques, such as cold pipe bending and hot pipe bending, which can achieve more complex pipe bending, but usually require more specialized equipment and technology.
Each pipe bending method has its applicable scenarios, and the selection of the appropriate method depends on factors such as specific processing requirements, pipe materials, and costs. Understanding different pipe bending methods can help practitioners in the metal processing industry make informed decisions based on actual conditions and improve production efficiency and quality of pipe processing.
The main structure of the tube bending machine is usually composed of a base, a bending rod, a hydraulic cylinder, a guide rail and a control system. The bending rod is the main component used to apply force to bend the pipe.
During operation, the pipe is clamped on the bending rod, usually with clamps or chucks to fix the two ends of the pipe, ensuring that the pipe is firmly placed on the bending rod.
tube bending machines are usually equipped with a hydraulic system to provide the pressure applied by the bending rod. The hydraulic system consists of hydraulic cylinders, oil pumps, control valves and oil tanks.
When the hydraulic system is activated, the pressure in the hydraulic cylinder will be transferred to the bending rod to generate a certain force. This force causes the pipe to bend and bend according to preset angles and curves.
tube bending machines are usually equipped with a control system to adjust the force applied by the bending rod and the bending angle of the pipe. The operator sets the required bending parameters through the control system to ensure precise control of the bending process.
