Abstract

Abstract In a high density solenoid operated multiple punch apparatus, having a punch head provided with the plurality of closely-spaced large bores arranged in column and rows that extend partially through the punch head from the top side, solenoid elements mounted in the large bores, a plurality of holes with a diameter smaller than the large bores aligned with the large bores and extending the remaining distance through the punch head to the bottom side, push rod elements slidably disposed in the holes actuated by the solenoid elements, the improvement being A cooling system for the punch head which includes a plurality of small bores arranged in rows in the bottom of the punch head terminating short of the top surface and positioned in the area between the plurality of large bores, a plurality of elongated grooves in the bottom surface of the head located between rows of the plurality of holes and forming a recessed chamber connecting a row of the small bores, a plate seated in each of the elongated grooves with each plate separating the associated groove into a first manifold chamber located between the plate and the bottom of the groove and a second manifold chamber on the opposite side of the plate, tubes disposed in and extending through each of the plates with each tube concentrically located in one of the small bores, and openings to introduce liquid in one of the manifold chambers and remove liquid from the other manifold chamber.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 250 words
In a high-density solenoid operated multiple punch apparatus having a punch head provided with a plurality of closely spaced large bores arranged in columns and rows and extending partially through the punch head from the top side, solenoid elements mounted in the large bores, a plurality of holes with a diameter smaller than the diameter of the large bores aligned with the large bores and extending the remaining distance through the punch head to the bottom side, push rod elements of the solenoids disposed in the holes, the improvement comprising: a cooling system for the punch head which includes a plurality of small bores arranged in rows in the bottom of the punch head terminating short of the top surface and positioned in the area between the said plurality of large bores, a plurality of elongated grooves in the bottom surface of the head located between rows of the said plurality of holes and forming a recessed chamber connecting a row of said small bores, a plate seated in each of the elongated rows with each plate separating the associated groove into a first manifold chamber located between the plate and the bottom of the groove and a second manifold chamber on the opposite side of the plate, tubes disposed in and extending through each of the plates with each tube concentrically located in one of said small bores, and means to introduce liquid in one of said manifold chambers and means to remove liquid from the other manifold chamber.
Claim 2
Dependent Claim 250 words
In a high-density solenoid operated multiple punch apparatus having a punch head provided with a plurality of closely spaced large bores arranged in columns and rows and extending partially through the punch head from the top side, solenoid elements mounted in the large bores, a plurality of holes with a diameter smaller than the diameter of the large bores aligned with the large bores and extending the remaining distance through the punch head to the bottom side, push rod elements of the solenoids disposed in the holes, the improvement comprising: a cooling system for the punch head which includes a plurality of small bores arranged in rows in the bottom of the punch head terminating short of the top surface and positioned in the area between the said plurality of large bores, a plurality of elongated grooves in the bottom surface of the head located between rows of the said plurality of holes and forming a recessed chamber connecting a row of said small bores, a plate seated in each of the elongated rows with each plate separating the associated groove into a first manifold chamber located between the plate and the bottom of the groove and a second manifold chamber on the opposite side of the plate, tubes disposed in and extending through each of the plates with each tube concentrically located in one of said small bores, and means to introduce liquid in one of said manifold chambers and means to remove liquid from the other manifold chamber.
Claim 3
Dependent Claim 29 words
