Stretch-bending die

Abstract

The application discloses a stretch bending forging stamping die, and particularly relates to the stretch bending stamping technical field, and comprises a lower die, a controller, two bending side slot templates and an anti-rebound stamping assembly; wherein the anti-rebound stamping assembly comprises two groups of transverse electromagnets, two groups of vertical electromagnets, a plurality of calibration pressure sensors, a sleeve column, an inclined slot plate and an inclined block. The anti-rebound stamping assembly is adopted, the stamping rebound problem of the left side surface of the aluminum alloy precision die forging is avoided, meanwhile, the right side surface of the aluminum alloy precision die forging also will not rebound, the precision of the stretch bending stamping of the aluminum alloy precision die forging is greatly improved, thereby the problem that the aluminum alloy precision die forging material rebounds due to the elastic recovery characteristics, the size deviation of the aluminum alloy precision die forging occurs after the aluminum alloy precision die forging is separated from the die, and the precision of the stretch bending stamping of the aluminum alloy precision die forging is greatly reduced.
