Radius sheet metal parts

Radius sheet metal parts

Bend Radius Sheet metal brakes are generally used to curve the material into the desired parts geometry. The Bends, which are in a similar plane, requires to be designed in a similar direction in order to prevent part reorientation, so as to save both the time and money. Maintaining the consistency of the bend radius will as well make the parts to be more cost-effective.

Production process

The process of bending

During the process of bending Radius sheet metal parts, the external fibres (blue), to be exact the outer of the curved piece, are usually stretched. The inside fibres (red), the inner of the curved part, gets compressed. There are neutral fibres between the inner and the outer fibres. This part is not stretched or compressed. The Minimum bending radii should be adhered to so as to avoid quality losses that are usually caused by the stretching as well as compression. And If the curving radius is lesser than the minimum value, breaks appear on the outer, severe (pinches) on the inner along with the cross-section alterations in the curving zone. Therefore there can be a risk of breaking the work piece. Several factors are very vital in determining the minimum curving radius of the Radius sheet metal parts, for instance, the plate / Sheet thickness, and the Material strength, the Bending speed, the Machine, the method of Bending, and the direction / Grain of rolling.
