Problems and solutions of sheet metal bending processing

In the process of sheet metal bending in sheet metal processing, many problems are often encountered. Understanding some problems that need attention and solutions can provide solutions for the next step in sheet metal bending, so as to achieve faster and more efficient production and manufacturing.

Sheet metal bending is a common manufacturing process used to create parts with specific shapes and dimensions. It involves applying force to a piece of sheet metal to bend it into the desired shape. There are several problems that can arise during the sheet metal bending process, including the following:

Springback: This is a common problem that occurs when the sheet metal returns to its original shape after being bent. It is caused by the elastic properties of the material, and it can be difficult to predict and control.

Wrinkling: This is another common problem that can occur during sheet metal bending. It is caused by excessive stretching of the material, and it can lead to weakened or distorted parts.

Splitting: This is a problem that can occur when the bending force is too high, causing the sheet metal to split along the bend line. It can also be caused by using a tool with a sharp edge that cuts into the material.

To avoid these problems, it is important to use the appropriate bending equipment and techniques. This may include using a press brake with a die that matches the desired bend radius or using a technique called "air bending" to minimize stretching and wrinkling. It is also important to properly set the bending force and use lubrication to reduce friction and prevent damage to the material.
