When making sheet metal parts, in order to facilitate processing, it is usually necessary to bend the required plates and process the flat plates into the desired shape. During this bending process, the curved part presented at the bending point is called the bending radius. Generally speaking, the bending radius affects the forming effect and processing difficulty of sheet metal parts, and is one of the key factors that needs to be considered.
The bending radius is closely related to the plate thickness, and it is generally required that the bending radius be at least a few times the plate thickness. Specifically, when the plate thickness is thin, the bending radius can be relatively small, about twice the thickness of the plate; When the plate thickness is thicker, the bending radius needs to be gradually increased, preferably greater than or equal to 4 times the plate thickness. This not only ensures the forming effect of sheet metal parts, but also avoids quality problems such as bending defects and cracks.
In addition to plate thickness, there are other factors that also affect the bending radius and need to be considered when making sheet metal parts. For example, factors such as material hardness, elastic modulus, plate width, frame length, die width, and punch diameter can also affect the bending radius and the forming effect of the entire sheet metal part.
In the production process of sheet metal parts, the bending radius is closely related to the plate thickness. The size of the bending radius determines the forming effect and processing difficulty of the sheet metal parts. Generally, the bending radius is required to be at least several times the plate thickness. It should be noted that in addition to plate thickness, there are other factors that can also affect the bending radius, which need to be comprehensively considered during the manufacturing process.
