Description

Quick die changing device of sheet metal bending machine Technical Field The utility model relates to the field of metal processing machinery, in particular to a rapid die changing device of a sheet metal bending machine. Background The rapid die changing device of the sheet metal bending machine is one of key technologies for improving production efficiency and reducing die changing cost in modern manufacturing industry. The development of the method closely follows the trend of industrial automation and intellectualization, and shows remarkable advantages in a multi-variety small-batch production mode, the early bending machine die change relies on manual operation, and the die is required to be fixed through mechanical structures such as bolts, pressing plates and the like, so that the method takes a long time of several hours.
