How To Make an Arc in Sheet Metal

Bending is one of the most common sheet metal fabrication processes. Bending is done by applying a force to the workpiece. The force must exceed the yield strength of the material to achieve plastic deformation. Then how to make an arc indentation on sheet metal? Here are a few ways to make arc indentations in sheet metal:

Make a Curve with a Radius

If the bending radius of the arc workpiece is less than R30, it can generally be bent directly by means of a circular plate bending die. As for how to make an arc with sheet metal: When the top mold is installed, it is recommended to use a top mold fixing method which makes it convenient for dismantling. When adding new prints, reducing costs will also help. The product produced by this process is of high precision and accurate size, and is suitable for largescale precision sheet metal components.

Generally, for arc workpieces with a radius smaller than R30, and the job size tolerance requirements are not high, one round tube with a diameter equal to the arc of the sheet metal section can be directly placed on the surface of the metal plate. The direct bottom mold uses a V-groove with a width greater than the arc diameter. Use the common top mold tip to press the round pipe and apply it to the metal sheet to achieve the forming purpose.

Make an Indentation with Radius > R30

Generally, for arc sheet metal with a radius greater than R30, the segment arc can be opened, and according to the size to calculate how much bending time is required to bend the shape of the shape, so that the size of the position of each bending can be adjusted. counted. Then calculate the angle of each bend according to the relationship between the total arc angle and the total numbers of bends.

When making sheet metal parts with this process, for the same arc size, the greater the number of bends, the better the effect and the smoother the surface. When bending such a product, the starting point of the dent ram stroke can be adjusted to increase the bending speed. It is important to know several ways to make arc bends in the bending process in metal fabrication.
