Metal bending is the process by which a metal is deformed using matrices. When the sheet metal is bent, the outer surface of the metal is stretched and the internal is compressed, which leads to direct stretching. Thus, machining metal bends means working properly with equations, such as bending resolution and bending or bending, to get the right thing. Bending does not increase or decrease the surface area of the metal, it only changes shape. Bending is performed using die sets or metal brakes. The bending of the sheet metal is placed on the die and held in place with clamps or gauges. The force is applied with a press to get the right shape. There are various types of metal bending methods used for industrial purposes to achieve the desired result. These include:
- Rolling: also called cold bending or pyramidal rolling, sheet metal is held between rolls placed in a pyramid shape and passing through each. It is the most economical industrial method used to bend steel.
- Hot bend: in this method, heat is directly applied to the metal using a flame or furnace to obtain a bend. A hot bend ideally returns in case of repair.
- Rotary bend: this method mainly uses a stamp. The metal to be bent is clamped and passes through the matrix to obtain a stamp, if it is formed. This method is most suitable for obtaining the desired results in the machinery and parts industry.
- Induction bending: this method uses both heat and pressing. The desired section of the sheet is heated using a coil, then passed through a matrix and is extremely cooled using water directly.
Stamps and presses are also used to bend metal, and depending on the amount of force used, the thickness of the material and the desired angle, there are different types of metal bending methods. These include air bending, bottom and chasing, V-bending, U-Die bends, wiping bends, double bends, and swiveling bends. To get the right result, it is important to follow certain tricks for bending the metal.
First, in order to reduce to virtually minimize all changes to the settings, it is ideal to maintain the same radius for all parts. Secondly, to achieve the best results, it is always reasonable to maintain the same material thickness. Thirdly, always bending perpendicular to the direction of rolling instead of bending parallel to the direction of rolling in order to avoid destruction or rupture of the metal.
I hope this information and metal bending technique will help you.
