Tools Positioned By Template Patents (Class 83/619)
  • Patent number: 8770077
    Abstract: A punch press device has a lift that can move up and down with respect to a workpiece and a punch that is supported by the lift and can move up and down with respect to the lift. Further, the punch press device has a switching member that reciprocates between a position where the punch is constrained so that it moves down together with the lift and a position where the punch is released so that it moves up with respect to the lift. The punch press device has two electromagnetic solenoids for reciprocating the switching member. The first electromagnetic solenoid moves the switching member in a first direction, and the second electromagnetic solenoid moves the switching member in a second direction opposite to the first direction.

  • Patent number: 7032490
    Abstract: A hole punch has a length in a first direction, a plurality of punch blocks each having a sinusoidal first guide surface, a slider movable along a frame in the first direction, and a roller connected to the slider at a position to engage the first guide surface of each punch block. Each punch block is fixed in the frame in the first direction and is moveable in the frame in a second direction perpendicular to the first direction. Each punch block also includes at least a punch head facing the second direction, and a retracting mechanism for urging the punch block in opposite the second direction to an initial position. When the slider moves in the first direction along the frame, the roller pushes the first guide surface near the middle of the punch block moving the punch block in the second direction to punch holes.

  • Patent number: 6679146
    Abstract: A die and method of gang punching selective holes in thin sheet materials such as greensheets are provided in which slugs of greensheet material formed during the punching operation easily fall through the die and are removed. The die uses a number of plates one of which is a window plate having openings corresponding to openings in a die plate disposed thereon. The window plate openings have a larger diameter than the die plate openings and also a plurality have an oval shape which oval shape openings provide less resistance to the falling slugs and facilitate removal of the slugs from the die. The window plate also preferably has a central grid open area with the remainder of the plate having vertical through-holes corresponding to the through-holes of the die plate. The die also preferably employs a die plate made from at least two sheets of material, i.e.

  • Publication number: 20020002891
    Abstract: An alignment device for aligning a punch tool to punch a design into a sheet media. The alignment device comprises a base platform having at least one sheet media receiving area. The base platform has at least one punch tool receiving area with at least one punch tool mount disposed therein. The punch tool mount is configured to removably secure the punch tool, and a portion of the punch tool mount protrudes into the sheet media receiving area. The device also comprises first and second guide edges disposed angularly from at least one of the punch tool mounts. The first guide edge disposed on one side of the punch tool mount. The second guide edge disposed on an opposite side of the punch tool mount. When the punch tool is secured in the punch tool mount with the punch tool protruding into the sheet media receiving area and when the sheet media is placed in the sheet media receiving area and along the first and second guide edges, the punch tool is positioned to punch the design into the sheet media.

  • Patent number: 6223636
    Abstract: A gang-punch pin apparatus for punching selected hole patterns in thin sheet materials such as greensheets is provided. The gang-punch pin apparatus uses program plates in the punch apparatus which plates are positioned intermediate the non-punching end of the punch pins and a clearance plate wherein punch pins not used for punching a particular layer of the MLC are retracted into during punching. At the other punch pin locations, the punch pins, upon activation of the punch apparatus by compressing an expandable chamber, usually by application of a force on the punch apparatus, are extended through the lower portion of the punch apparatus to form vias in a greensheet. A die apparatus is also provided for use with the punch assembly to form the vias and to remove the punched material (slugs) from the die apparatus. The gang punch-pin may be shorter than conventional pins and be made at a low cost because of the thin sheet metal plates preferably used to make the component parts of the punch and die apparatus.

  • Patent number: 5996206
    Abstract: A method and apparatus for facilitating the installation and alignment of side punches onto the internal drum of an imaging system. A side of the internal drum is provided with a T-shaped slot for movably positioning a plurality of side punches about the cylindrically shaped imaging surface of the internal drum. The proper radial alignment of the side punches along the T-slot is achieved using a unique band template. The band template includes a plurality of notches, each of which indicates the correct positioning of the pin of a side punch to be installed on the internal drum.

  • Patent number: 5979281
    Abstract: A produce slicer and chopper device (10) comprising a housing (12) having a large compartment (14) and a small compartment (16) in a side by side relationship. A first blade assembly (18) is mounted onto a top of the housing (12) to be manually operated to extend down into the large compartment (14), so as to vertically slice and chop vegetables, fruit and cheeses placed within the large compartment (14). A second blade assembly (20) is mounted onto the top of the housing (12) to be manually operated to extend down into the small compartment (16), so as to vertically slice and chop vegetables, fruit and cheeses placed within the small compartment (16). A third blade assembly (22) is mounted onto a side of the housing (12) to be manually operated to extend sideways into the large compartment (14), so as to horizontally slice and chop vegetables, fruit and cheeses placed within the large compartment (14), when the first blade assembly (18) is in an outwardly extended position.

  • Patent number: 5463922
    Abstract: A punch for making a multiplicity of holes in a line even through a multiplicity of sheets of paper put one upon another includes a multiplicity of vertically disposed and vertically movable cutting tools supported in a row by a horizontally disposed rail. Each tool is provided with a horizontally disposed actuator pin attached to it at right angles to it. A slider is slidable along the rail for causing the pins to move the tools vertically one after another. The slider has a pair of curved guide grooves in which the opposite ends of each pin are engageable, or a roller having a pair of annular surfaces which are engageable with the opposite ends of each pin, so that the pins and thereby the tools may be vertically movable.

  • Patent number: 4509397
    Abstract: A perforator of enhanced performance is disclosed which comprises a punch and a perforation jig comprising upper and lower oblong sheet retainer plates adapted to hold paper sheets, so that in the course of perforation, the perforation jig will retain the punch fast in position with respect to the paper sheets and prevent the punch from being shaken in the vertical direction relative to the perforation jig. The perforator of this invention is constructed so that when the front portion of the punch is abutted against the upper sheet retainer plate forming part of the perforation jig, a punch-supporting member of the lower sheet retainer plate protruding outwardly from the upper sheet retainer plate advances into a recess extended from the front side to the rear side of the punch adapted to receive insertion of paper sheets and, consequently, the perforation jig is allowed to hold the punch safely.
