Description

Material stripping mechanism for blanking and punching machine

Technical Field

The utility model relates to a take off material mechanism especially relates to a take off material mechanism based on that annular air cushion constitutes that is applied to on automatic blanking punch press.

Background

At present, stripping mechanisms with rigid structures are used for stripping materials during automatic stamping production of composite die strip materials in the industry; however, in actual use, it was found that the stripping stability of the stripping mechanism of a rigid structure was affected by the appearance of the workpiece, and it was not possible to achieve a universal use. Therefore, enterprises begin to research and develop elastic stripping mechanisms, but the acting time cannot be controlled by common elastic stripping materials, the common elastic stripping materials all adopt springs to provide stripping force, the springs deform under the action of external force, and the springs recover to the original shape after the external force is removed, so that a die finishes stamping, and the die begins to strip materials when an upper die and a lower die are separated; that is, when the common elastic stripping device is used, the stripping is started just after the punch returns, and the synchronization with the material receiving device is difficult to realize and the generalization cannot be realized. For this reason, a mechanism for stripping materials by providing elastic force different from the conventional spring is required.
