Pneumatic intelligent folding center upper pressing die hinge die and using method

Abstract

The invention discloses a pneumatic intelligent folding center upper pressing die hinge die and a using method, the pneumatic intelligent folding center upper pressing die hinge die comprises a die body, the bottom of the die body is provided with a main body knife edge, the die body is provided with a driving mechanism, a movable ear knife taking the driving mechanism as a power source and rotating relative to the die body, and a positioning block suitable for limiting the position of the movable ear knife; the output end of the driving mechanism is connected with the movable lug cutter to drive the movable lug cutter to rotate, the bottom edge of the movable lug cutter is provided with an auxiliary cutter edge used for being horizontally aligned with the mold body, and the bottom of the outer side of the movable lug cutter extends to form a lug mold. When the bending is finished and the die is withdrawn, the air cylinder pushes the movable ear knife and the knife edge of the movable ear knife to be quickly withdrawn from the workpiece, so that the friction between the movable ear knife and the workpiece is effectively controlled, the product bending stability is enhanced, the product quality is greatly improved, the lifting speed of the movable beam of the intelligent edge folding center is not influenced by the withdrawing of the movable ear knife from the workpiece, the bending time is shortened, and the production efficiency is improved. And the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of bending equipment, and in particular relates to an upper pressing die hinge die for a pneumatic intelligent hemming center and a method for using the same. Background technique [0002] The upper pressing die is a commonly used process equipment in the intelligent hemming center. The fixed shape of the ordinary upper pressing die is only suitable for open bending. When encountering the need for semi-closed bending and combined bending, the advantage of the upper pressing die hinge die that can adjust the length of the die solves a major industry problem. But there are still defects and deficiencies in the upper pressing die hinge die in the prior art: [0003] 1. When the bending is finished and the mold is withdrawn, in order to prevent the cutting edge of the movable ear knife from pulling the workpiece from the workpiece, it is necessary to reduce the lifting speed of the movable beam in the intelligent foldin...

AI Technical Summary

Problems solved by technology

[0003] 1. When the bending is finished and the mold is withdrawn, in order to prevent the workpiece from being pulled out when the edge of the movable lug knife is pulled out from the workpiece, it is necessary to reduce the lifting speed of the movable beam at the center of the smart folding center, that is, to lift it slowly, which greatly reduces the speed of the smart folding. Edge Center Productivity

[0004] 2. Due to the friction between the knife edge of the movable ear knife and the surface of the workpiece, the knife edge of the mold is worn and the service life of the mold is reduced
