In the world of metalworking, metal profile bending is a key process for transforming raw materials into finished products with specific shapes and dimensions. This technology requires not only precise calculations and manipulations, but also a deep understanding of material properties. From steel beams in building structures to lightweight alloys in aerospace, the application of metal profile bender technology is ubiquitous, and its development and innovation have pushed the progress of the entire metalworking industry. In this article, we will explore the basic principles of metal bending, common methods, equipment types and their applications in different scenarios, revealing the full picture of this technology from basic to advanced applications.
Basic Principles of Metal Bending
Metal bending is a process of plastic deformation of metal profiles by applying external force. This process involves the elastic and plastic properties of the material as well as the precise control of the bending machine. During metal profile bending, the profile is subjected to compressive and tensile forces that cause it to bend in the bending region. Understanding this principle is essential to selecting the right bending method and equipment.
Common bending methods
Metal profile bender technology includes a variety of methods, each with its own unique application scenarios and advantages.
- Bottom Bending: This method bends a metal sheet by placing it into a specifically shaped mold and stamping it to the bottom of the mold surface, and is suitable for applications that require high-precision bending.
- Air bending: In contrast to bottoming-out bending, air bending keeps the punch in the air until it returns to its initial position, and is suitable for bending angles that require a certain degree of flexibility.
- U- and V-bending: These two methods use a U- or V-shaped die to change the bending angle by adjusting the die section, and are suitable for simple bending applications.
- Roll Bending: This method is suitable for producing bends similar to cones and tubes, where the bending radius is controlled by adjusting the position of the upper roll and the spacing between the lower rolls.
- Edge bending: This is suitable for applications where the edge size is large and not suitable for reaming, where the workpiece is deformed by clamping it and applying force.
Types of equipment and their application
There are various kinds of profile bending machines, including Profile bending machines, CNC bending machines and hydraulic bending machines. Choosing the right machine requires consideration of the type of material, the required bending radius and angle, productivity and cost.
