Description

Technical Field

[0002] A bending mechanism is a tool used to bend sheet metal. It is used to shape a blank into a part with a specific shape and size under the pressure of a bending machine. Depending on the bending shape, the shape of the bending die is also very diverse. Although the sheet metal die bending mechanism currently used can meet the normal use requirements, it still has defects in actual use. For example, the material discharge of the sheet metal die bending mechanism currently used is relatively inconvenient.
