Description

Technical Field

[0002] A certain type of sheet metal workbench contains a rounded corner supplement part, which has a quarter-circle arc in two perpendicular directions. Sheet metal part forming mainly includes two methods: stamping and bending. If this part is formed by stamping, it requires the design of complex stamping dies, resulting in high production costs. Bending is usually completed using a bending machine, which has low processing costs. However, bending machines can only form arcs in one direction; arcs in the other direction cannot be formed. Therefore, it is not convenient, quick, or low-cost to form arcs in both directions for sheet metal parts. Summary of the Invention
