  • Patent number: 10569322
    Abstract: An improved forged wheel trimming die, including a connecting rod, a lower die base lower plate, a bottom plate, a stripper guide pillar, a knockout rod, an ejector block, a lower die base stiffened plate, a lower die base upper plate, a lower die, a stripper plate, follow-up retainer plates, a shearing blade and a trimming rod. The improved forged wheel trimming die has the advantages that by adding two follow-up retainer plates to the stripper plate of the die, burrs of a forged wheel blank are constrained along the radial direction during the cutting, thereby avoiding breakage due to excessive deformation; in this way, the burrs can be protected from damage and knocked out successfully by the knockout rod after being cut off from the blank.

  • Patent number: 6397713
    Abstract: An apparatus and methodology are presented for automatically infeeding workpieces to a saw. A first workpiece is selected at an input station. A servo-driven friction belt system is connected to the input station, and advances the workpiece under a laser projection system. The laser projection system projects a laser pattern onto the workpiece, the laser pattern corresponding to one of a plurality of patterns corresponding to the blade configuration of a fixed arbor gang rip saw. Finally, there is a pinch roller system for removing the workpiece from the friction belt system and moving the workpiece into the saw, while maintaining the workpiece's orientation under the laser pattern. Also provided is a sensor for measuring the board width while moving on the servo-driven friction belt system, where the width is input to a computer controlling the friction belt system and which determines the optimum laser pattern.

  • Patent number: 5114394
    Abstract: A single, fluid pressure-operated cylinder, which has a conventional slitter blade and punch releasably secured to the lower end of its piston rod, is secured to a plastic bag making machine so that the operating ends of the blade and punch project toward a stationary, horizontal support surface across which overlapping plastic webs pass during bag manufacturing. The webs are secured against movement during a slitting and punching operation by a pressure plate, which is also mounted on the piston rod for movement thereby into engagement with the plastic webs to clamp them against the stationary support surface during the initial advance of the rod. As the rod continues to advance it moves the blade and punch through the now-clamped plastic webs, after which the piston rod is retracted and the parts return to their inoperative positions.

  • Patent number: 4648298
    Abstract: A shearing device which uses an in-line design wherein bearings are aligned with the moving blade so that lever arm forces are not produced between the movable blade and a fixed blade. This provides for highly accurate and clean cuts of printed circuit boards. The fixed lower blade is vertically oriented to provide clearance on both front and back portions for placement of tooling means to hold printed circuit boards in the shear to minimize scrap cut from the boards. Additionally, the clearance provided by the vertically oriented lower blade allows for zero space cutting of the printed circuit boards adjacent components mounted on the printed circuit boards. An optical curtain is also used which is directly aligned with the movable upper blade so that obstructions can be detected directly in the path of movement of the upper blade.

  • Patent number: 4428264
    Abstract: An apparatus for forming an element-free gap in a continuous slide fastener chain. In the apparatus, a reciprocating punch blade has cutting edges along opposite sides and is relieved at opposite ends along the cutting edges so as to form a pair of wing portions disposed one on each side of the punch blade. An elongated slot formed in a die for receiving the cutting edges has at its opposite ends a pair of lateral branches disposed one on each side of the elongated slot in opposite relation to the sides of the punch blade on which the wing portions are disposed. The wing portions and the lateral branches jointly serve to protect a pair of coupling elements disposed adjacent to the opposite ends of the space section from being cut by the punch blade.
