The drive holes are engaged by drive pins (46) extending outwardly from the drive drum (22). Rotation of the drive drum causes the pins to engage the drive holes and advance the belt with the drum. Each drive hole has a hub (58) which is shaped to conform generally to a tapered and contoured edge (48) of a drive pin. At least a portion of the hub protrudes out of the planar surface (56) of the belt, and the pin edge and the lower surface (62) of the hub are mutually shaped to define rolling contact therebetween with no contact between the pin edge and the inner edge (54) of the drive hole.

  • Patent number: 5711179
    Abstract: An indexing conveyor apparatus is driven with respect to a press having a reciprocal ram and bolster plate. An elongated conveyor is connectible to the press for moving material with respect to the press. The conveyor includes an endless conveyor belt disposed about a drive pulley at one end and an idler roller at an opposite end. A flexible member is connectible between the conveyor and the reciprocal ram for converting reciprocating movement of the ram into indexing movement of the endless conveyor belt through the drive pulley. The flexible member preferably includes a webbing material wound about a spool. The spool is spring biased to rewind the webbing on the spool while the ram is driven toward the bolster plate. As the ram is moved away from the bolster plate, the spool acting through a clutch drives the drive pulley to index the endless conveyor belt.

  • Patent number: 5572926
    Abstract: An apparatus and method for unloading presses with a nonhydraulic press unloader. The apparatus generally includes a support frame, a reciprocating tray, a tray arm, a link arm, an actuating arm, and an attachment arm. The support frame has a pair of support frame members having top surfaces. A tray roller, for supporting the reciprocating tray, is rotatably mounted to each end of the support frame member. The tray arm is slidably engaged with the top surface of one of the support frame members and is pivotally attached to the link arm. The midsection of the tray arm is pinably connected to the reciprocating tray. The actuating arm is pivotally connected to the other end of the link arm and to the support frame. A pickup roller is rotatably attached to the actuating arm near its midsection. A release roller is rotatably attached to the actuating arm also near the midsection and adjacent the pickup roller. As the press ram rises, the arms draw the tray in between the gap presented by the separating die halves.

    Abstract: A conveyor belt and drive structure are disclosed for use with a conversion press in which an upper level of an endless metallic conveyor belt, preferably of stainless steel, is positioned between upper and lower tooling in the press. The conveyor belt is formed by seam welding together the ends of a length of thin flexible metal, and includes a plurality of transversely and longitudinally spaced shell-receiving carrier apertures. The edges of the conveyor belt at the ends of the weld seam are relieved with an elongated notch shape having corners formed on a radius to eliminate from the belt stress concentrations which may occur during the welding process.

    Abstract: In production of a lock nut used for fastening in cooperation with a bolt, a tubular material of a polygonal transverse cross section is machined into a crude block integrally made up of an angled main body and a truncated cone having a common, circular cente hole which is then tapped, a series of crude blocks are periodically and intermittently supplied to and registered at a shaping center provided on a holder assembly, each crude block is compressed with a compression mould to deform its tapped hole into a polygonal transverse cross section in the region of its truncated cone, and a lock nut thus produced are delivered out of the shaping center after compression. The process is fully automatized and the deformed transverse cross section of the rapped hole assures halmless, elastic, blanced fastening on a bolt in screw engagement of the lock nut.

  • Patent number: 5146781
    Abstract: A method of treating hot metal slabs (6) aims to reduce the width of the slab (6) produced by a continuous casting process to avoid the need for the prolific number of moulds otherwise required to produce slabs of various widths. In order to achieve this the hot metal slab (6) is presented, with its width dimension vertically oriented, to a pressing machine (24) having a vertically movable top platen (26) and a fixed bottom platen (28). The slab (6) is incrementally displaced, longitudinally, through the pressing machine and pressing forces are applied to its opposing edges by the platens, to reduce its width. Subsequently, the slab (6) is turned so that its width dimension is oriented horizontally and rolled between the horizontal rolls of a rolling mill (22). An apparatus for performing the method is disclosed.
