An introduction to sheet metal bending
Sheet metal bending is an important process in many manufacturing industries due to the way it can create complex shapes and components from flat metal sheets efficiently and cost-effectively. This blog post will provide a brief introduction to sheet metal bending including the different bending processes.
What is Sheet Metal Bending?
The process of sheet metal bending involves deforming or bending the metal sheet along a straight line or curve by applying force. Sheet metal bending is used in the manufacturing of various products including automotive parts, building materials, household appliances and many other consumer and industrial goods.
Bending machines are now becoming automated which is increasing productivity and accuracy.
Different Methods of Sheet Metal Bending
Press brake bending – In this method, a piece of sheet metal is placed over a V-shaped die and a punch is used to bend the metal along a straight line. The punch applies force to the metal which causes it to bend around the die.
Roll bending – In roll bending, the sheet metal is passed through a series of rollers that progressively bend the material into a curved or cylindrical shape. This method is mostly used for creating cylindrical shapes like pipes, tanks and drums. Machinery specialists such as www.cotswold-machinery-sales.co.uk/euromac-bending-machines/horizontal-bending-machines offer Euromac bending machines which are good for thick or small pieces of metal.
Rotary bending – This method involves clamping the sheet metal workpiece onto a rotary mechanism and then using a wipe tool or a die to bend the metal around a fixed radius or shape.
Stretch bending – In stretch bending, the sheet metal is clamped at both ends and one end is pulled or stretched while the other end remains stationary, causing the metal to bend along a curve.
What Can Affect the Bending Process?
The bending process can be affected by various factors including the thickness, strength and ductility of the metal, the radius of the bending and the tools used. It is also important to use the correct amount of lubrication to prevent any cracking or wrinkling in the bending process.
