Sheet metal bending is one of most common sheet metal fabrication processes that involve bending of sheet metal into desired shape. This process involves a sheet metal bending machine that applies force on metal sheets. The force is applied using a special sheet metal bending tool.
The machine simply applies force using tools that bending and deforming metal sheets beyond its yield point. Once material is deformed into required shape beyond its yield strength, it will retain that shape until forcefully changed.
There are three main things involved in this process, a tool, a die and the metal sheet. Tool and Die shape is prepared as per the sheet metal bending requirements.
Metal sheet is placed on the top of the die and a tool is used to apply force. Due to the force the metal sheet is forced into the die and it bends as per the shape of the tool and die.
V bending is a type of sheet metal bending where a V shape tool and die are used. The process is simple and fast. Metal sheet is placed on the die, and sheet metal bending machines apply force using its tool.
Tool and die shapes are exact machines with allowance for required thickness of metal sheets. This process of V bending is further divided into two main types. Air bending and bottoming.
Air bending is where the sheet bending tool does not fully bend the sheet up to the die bottom. There is always some space between the sheet and die bottom.
Bottoming is a process where a sheet metal bending machine forces the sheet up to the very bottom of its die. In this case the sheet touches the bottom of the die and takes the exact shape of the die cavity.
Roll bending is the second most used process of sheet metal bending. In this process a metal sheet can be bent or more precisely rolled into different shapes like rolls, tubes, cones and curved.
In this process sheet metal bending machines have three or more sheet metal bending tools called rollers. Machines roll these rollers that force the metal sheet to pass these rollers. These rollers also apply bending force on the sheet, forcing it to take the desired shape.
Swipe bending is another common method of sheet metal bending where the bending process is mostly done on any of the end sections of the sheet.
For this process metal sheet is gripped between dies where on the die has the shape on which the sheet will be bent. The sheet metal bending tool presses the sheet edge/end on the die, forcing it to take the sheet shape.
The bending corner radius is about the radius of the bend in the metal sheet. It is important to mention this radius as it will affect the strength as well as appearance of the final product.
The Sheet metal bending can be done in different directions. They can be bent in up, down, left, or right direction. The bending direction is very important to achieve the desired shape and orientation of the final product.
The shape & size of the new sheet affect the bending process. It is important to consider the sheet dimensions and its thickness as well as material properties.
The choice of sheet metal material affects its bendability, strength, and overall performance. Different metals have varying levels of ductility, which influences the ease of bending.
The design of the sheet metal bending tool and its die is important for achieving accurate bending. The tool and die design must match the sheet thickness. This is important to avoid defects like sheet tearing.
Bend allowance is the extra material needed in a sheet to account for bend during bending. In sheet metal bending factors like K-factor or the bend deduction are mostly used to calculate bend allowance.
It's important to mention tolerance for the dimensions of the bent sheet metal parts. This will affect all the tools, die and the bending process.
