ABSTRACT:
An die transfer and quick change system comprising at least four T-lift units installed in T-slots formed in the surface of the machine bolster. The T-lift units are installed in the bolsters so that there are at least two systems for positioning the die parallel to the machine or press and at least two systems for positioning the die perpendicular to the machine or press. A control mechanism is provided for selectively inflating and deflating the air bag in each of the T-lift units. The control mechanism provides for two separate T-lift systems which are inflated or deflated independently of each other. A pre-staging table is provided adjacent the machine or press bolster for pre-staging a plurality of dies thereon and for transporting selected dies to and from the machine. Utilizing the system of the present invention, an operator can move a die from the pre-staging table onto the machine or press bolster and thereafter accurately and properly position the die on the machine or press while minimizing the effort required and maximizing the speed and accuracy of the positioning. Then, upon completion of a production run, with the particular die installed in the machine or press, an operator can disengage the die from the machine or press, return the die to the pre-staging tble, move a second die from the prestaging table onto the press for precisely positioning the new die on the bolster with a minimum of time and effort and without outside assistance.
