Hot Rolled Bending Forming
Hot rolled bending forming is a process used to fabricate metal products from hot rolled material. Hot rolled material is heated to temperatures above the re-crystallization temperature and then deformed to desired dimensions. Hot rolled bending forming can be used to shape metal products for automotive, aerospace, construction, and many other applications.
Hot rolled materials used for hot rolled bending forming include aluminum, steel, and stainless steel. Material properties, such as yield strength, tensile strength, formability, and toughness are important in determining the right material for the application. The geometry of the final product, such as bend radius, size, and thickness, will also help dictate the choice of material.
When choosing a material for hot rolled bending forming, several factors must be considered. Generally, for most materials, the higher the yield strength, the greater the formability. Higher temperature materials are also more formable than lower temperature materials. This allows for the use of higher strength materials with greater bend radius than lower strength materials.
The size and shape of the bent product can also dictate the material used. For example, oval-shaped components are easier to form than circular components, and materials with greater strength are needed to form components with tighter bend radius. Additionally, components formed with hot rolled bending forming may require a more accurate shape than those formed with cold forming.
The hot rolled bending process can be used to bend a variety of complex configurations. Parts that have more curvatures and more complex contours may be better suited for the hot rolled bending process. Complex contours including wave surfaces, eccentrics, conicals, and the like, can be created with hot rolled bending.
The process begins with the heated material entering the press. A die is then placed in the die cavity of the press and the hot rolled material is then forced between the die and press tool to form the desired shape. The press tool exerts pressure onto the material as it is pushed through the cavity in the press. After the material is deformed and the desired shape is achieved the material is then cooled down and removed from the press.
The hot rolled bending forming process can be used to form a variety of components for many industries. These components are used for various applications and can be formed to very tight tolerances and intricate shapes. Hot rolled bending forming is also a cost-effective way to form complex components.
The hot rolled bending forming process has many advantages over cold forming. Hot rolled forming can achieve tight tolerances and intricate shapes, while a lower strength material can be used due to higher formability. Additionally, hot rolled bending requires less force than cold forming and results in parts with improved surface finish.
Hot rolled bending forming can provide highly accurate parts with complex shapes and tight tolerances. The process is cost-effective, and components formed with the process often require less force than those formed with cold forming. As a result, hot rolled bending forming is an important process for a variety of industries.
