ABSTRACT:
An assembly for automatically feeding workpieces to and from a numerically controlled turret punch. A loader magazine having an adjustable volume for receiving a stack of workpieces is disposed on one side of a turret punch, and an unloader magazine having a similar adjustable volume for receiving a stack of workpieces is disposed on the opposite side of the turret punch. An ejector associated with a loader magazine ejects the top workpiece from the loader magazine to horizontally feed it into operative association with clamps of the turret punch. The turret punch clamps are moveable with respect to the punching tools, and the punching tools are moveable and operated to effect punching of the workpiece until it has a desired finished configuration. Then the workpiece is moved into engagement with rollers on the unloader magazine and powered into the unloader magazine, while the next workpiece is readied for movement from the loader magazine--or simultaneously with movement of the next workpiece from the loader magazine. Horizontally and vertically moveable locator stops are associated with the turret punch table to facilitate movement of the workpieces into engagement with the turret clamps. The loader and unloader magazines are also numerically controlled.
