Bending Methods and Techniques
Different bending methods are employed depending on the material, the desired bend, and the application. Understanding these methods helps in selecting the appropriate machine and process for specific requirements.
Rotary Draw Bending
Rotary draw bending is commonly used for precise bending of pipes and tubes. The method involves clamping the workpiece to a form and drawing it around the form to create the bend. It is ideal for tight radii and consistent bends and is widely used in the automotive and aerospace industries.
Press Bending
Press bending uses a press to push the workpiece against a die, forming the desired angle. This method is straightforward and suitable for large-radius bends. It is commonly used in construction for bending structural components.
Roll Bending
Roll bending involves passing the material through a series of rollers that gradually bend it to the desired curvature. It is ideal for creating large-radius bends and curves in metal plates and sections. This method is essential in producing components for large structures like roofs and bridges.
