What Is Metal Bending?

Metal bending refers to the process in which metal is bent through die-sets. When metal sheets are bent, the exterior surface that is stretched, and the inner is compressed, in order to achieve the perfect stretch. So, managing metal bending requires a thorough understanding of equations like bend allowance or bent or bend deduction in order to find the ideal solution. Bending doesn’t increase or reduce the surface area of the metal. It just alters its shape. Bending is done using bending press machine. The sheet of metal that is to bend put on a die, and then fixed using clamps or gage. The force is applied with the press to create the desired shape. There are various kinds of metal bending techniques that are used in industry to achieve the desired results..

This includes:

Rolling: Also known as cold bending, or pyramid rolling, the sheet of metal is held between the rolls in a pyramidal pattern and then rolled through each. It is the most cost-effective industrial method of bending steel.

Hot bending: In this process, the heat is applied directly to the metal by an electric flame or furnace to create the bend. It is the best method to resort for repair.

Rotary draw bending: This technique generally uses the die. The bent metal is clamped, then passed into a die till die is formed. This process is the most efficient for producing desired results in the machines and parts.

Induction bending utilizes both pressing and heat. The desired section of sheet is heated with coils, and then pushed through a die before being is cooled using water directly.

Dies and presses are employed for metal bending, and according to the force required as well as the material’s thickness and desired angle, there are various kinds of metal bending methods. These include air bending, bottoming, and coining, V-bending, U-Die bends, wiping die bending, double die bending and rotary bending. To achieve the best outcome, it is essential to be aware of certain bending techniques for metal.

To begin, in order to reduce the impact of any setup adjustments, it is best to use the same radius for every part. Additionally, for the best results it is always advisable to maintain the same thickness. Thirdly ensure that you bend perpendicular to the direction of rolling instead of being bent in a parallel direction in order to prevent breaking or fracturing the metal.

We hope that this knowledge and methods of bending metal will assist you.
