  • Patent number: 7954407
    Abstract: A steel rule die is disclosed which includes a bottom board with one or more cavity boards stacked on top of the bottom board. A metal plate is located on top of the uppermost cavity board. A top board is located on top of the metal plate. A plurality of rule slots are provided on the top board which define in plan view a generally rectangular or square configuration and a steel rule die is located in each of the slots. Each of the steel rules is generally flat to fit into a given slot and has a bottom portion adjacent the metal plate with a top portion formed into a cutting edge residing above the upper surface of the top board. Each of the steel rules extends on a longitudinal axis and has first and second end portions with the first end located approximately at a 45° angle to the longitudinal axis and one side of the same and the second end portion extending at approximately a 45° angle to the longitudinal axis and on another side of the axis.

  • Publication number: 20110016685
    Abstract: A method of reworking a head suspension removes a slider from the head suspension by pressing a blade from a first side toward a second side in a longitudinal direction of the slider to solder ball bonding, stopping the second side of the slider in the longitudinal direction with a holding mechanism, and forcing the blade to bite and cut the solder ball bonding to remove the slider from the flexure. The solder ball bonding is cut without applying extra force to components of the head suspension except the slider. The method improves product yield.

  • Patent number: 6779426
    Abstract: An apparatus is provided for improved retention of magnetically attractable die rules inserted into slots of a retaining board. In a die rule retaining board, a plurality of chambers are oriented substantially perpendicular to a die slot and the direction of insertion of a die rule into the retaining board. In one embodiment, each of the chambers has an open face to permit communication between the chamber and a die slot in the retaining board. A magnetic die rule retention device is located within each chamber and includes a contact face intended to contact and retain a magnetically attractable die rule inserted into a respective die slot. Once the die rule is completely inserted into the die rule slot, the contact face of the magnetic retention device exerts an attractive force against the die rule in the direction of the retention device slot and securely holds the die rule within the die slot.

  • Patent number: 5676032
    Abstract: A steel rule cutting die for cutting fixed patterns in a single or plurality of stacked material layers according to the shape of the steel rule. The invention provides for a decrease in the quantity of scrap material produced, by minimizing the amount of gap between adjacent cavities in the steel rule cutting die. Pre-sharpened steel rule is used with the cutting edge shifted to the outboard side of the cavity thus reducing the amount of compression or wedging of scrap material between adjacent cavities, and thus allowing adjacent cavities to be positioned closer to one another or to contact one another without reducing the ability to remove the scrap material after the cutting operation. Frayed scrap material can be evacuated through the base of the die by providing evacuation holes in the base substrate of the die as well as providing for evacuation of scrap material from marker notch locations along joined sections of adjacent cavities. A variety of cavity shapes can be accommodated.

  • Patent number: 5029505
    Abstract: An apparatus is provided for improved retention of steel rule dies inserted into slots of a retaining board. A plurality of chambers are oriented substantially perpendicularly to the direction of insertion and have open faces to permit communication with the slots. A spring is located within each chamber and is connected to a ball shaped member located at the open face. Upon initial insertion of the die, the ball shaped member causes the spring to compress. Once the die is completely inserted, the ball/spring assembly exerts a normal force against the die in the direction of the slot wall opposite the open face. Accordingly, the inserted steel rule dies are securely held within the slots.

  • Patent number: 4825740
    Abstract: The invention pertains to a cutting die or punch that comprises a hardened blade and a base portion which is relatively more compressible than the blade. The compressibility of the base allows it to deform under pressure more than the blade. The compressibility of the base provides for a reduction in the requirement to adjust the blade contact with the platen in areas of irregularity. The cutting die of the invention in effect achieves a self-leveling which reduces set-up time, and increases the operational life of the blade.
