Abstract: A system for punching at least one hole in at least one sheet-like material. In particular, a device and system that is uniquely configured and sized to be a table top unit for automatic punching of paper. The system has a sheet feeder, a sheet transport module and a punching die module that allows a punching die to be easily changed.

Abstract: A system is provided which utilizes a plurality of sequentially controlled magnetic repulsion punches arranged in a variable array to punch a constantly moving substrate. These punches are disposed adjacent the constant velocity substrate on which holes, or vias are formed as the punches are sequentially fired. The array of punches is placed at an angle with respect to the perpendicular of the direction of movement of the substrate. Thus, a delay is present between the time when the first punch must be fired and the firing of subsequent punches, due to the angle of the array. Therefore, due to this delay between the time the first punch must energized, and the energizing of subsequent punches a single power supply is capable of providing energy to a group of punches.

Abstract: The invention is an improvement to punches for placing one or more openings on the edge of a sheet of material. A collection of individual punch pins are carried within bores in a punch block. Movement of the pins is constrained by a corresponding collection of pneumatic actuators. The constrained pins are driven against a die block to affect the punching operation. To insure that the punch pins do not interfere with the operation of the pneumatic actuators between machine cycles, a fixed retraction guide cooperates with a relieved section on each punch pin to position each pin at one extremity of the bore within which the actuator travels.

A device for driving the punch pins includes a plurality of drive shafts each having at least three shaft portions disposed adjacent to each other, part of the shaft portions being formed of a magnetic material and the remaining part thereof being formed of a non-magnetic material. At least two electromagnetic coils are fitted around the shaft portions of each drive shaft, and a clutch mechanism disposed on one end of each drive shaft separably couples the drive shaft with the punch pin. The driving device greatly reduces the amount of heat generated by the electromagnetic coils to allow the adoption of an air cooling system, and increases punching force to assure positive working.

Abstract: A stamping tool for use in an auto-indexable tool station having a number of character inserts that can be rotatably moved below a striker area so that a thin metal plate or sheet of metal may be marked. The stamping tool allows for automatic adjustment of tool length for any variation in material thickness. A pneumatic cylinder actuates a mechanism that engages the key way in the head nut. The tool length is changed by the rotary motion of the auto-indexable tool station. The character housing is rotated by the indexable tool station through the punch key which moves the selected character insert to the striker area within the tool. The striker area causes the character insert which is spring biased to protrude lower than the character inserts that are not in the striker area. When the stamping tool is struck by the ram, only the character insert in the striker area will contact the material to be marked.

At any of these orientations, the ram may be actuated to cause the punch to extend downwardly below the punch assembly and through a sheet of material. The rotation of the punch assembly to different orientations allows a single punch to be used to punch holes of the shape but with differing angular orientations. The die holder receives a plurality of corresponding dies having openings therein corresponding to the punches.
