  • Patent number: 5454252
    Abstract: In a can body maker for the forming of a shallow metal cup blank into a relatively deep shaped cup body, a redraw sleeve for use in a redraw mechanism has a generally cylindrical body portion with a first end adapted to engage the redraw mechanism and an opposite, second end for contact with the shallow cup blank during the forming of the deep shaped cup body. The second end has a radially inwardly directed, circumferentially disposed, deformable face that facilitates uniform contact with the metal cup while compensating for minor misalignment of the cup and ram.

  • Patent number: 5454254
    Abstract: An air bag actuator is incorporated into the redraw motion assembly of a can body maker apparatus to maintain a cam actuated arm in compression during the reform cycle. Additionally, a housing is provided to enclose an air bag actuator, preventing axial displacement of the air bag and inadvertent damage to it during operations. The air bag actuator also functions as a pivotal link in the redraw system and eliminates the need for a complex pneumatic systems that include surge tanks, air supply tanks, and housing.

  • Patent number: 5435373
    Abstract: The fill chamber bore of a die-casting machine is lubricated and prepared for casting by inserting an elongated member into the die-end of the bore while spraying with lubricant. During withdrawal of the elongated member, a conical spray of gas directed toward the die-end drys the lubricant and sweeps vapor and flash, or solder, out of the die-end. The elongated member is preferably a flexible carrier which is guided between the bore and a path between the open die halves lateral to the bore. The lateral path is perferably defined by a tubular member supported by a vertical carriage mounted on a vertical mast for alignment of the flexible carrier with the fill chamber bore when the dies are open. The vertical mast can be mounted on a horizontal carriage moveable along a horizontal bore to preclude interference with normal operation of the die-casting machine.

  • Patent number: 5435205
    Abstract: A pedal for a vehicle has an integrally formed clevis, a central portion, and an integrally formed relatively flat foot engaging section. A lightweight, one-piece, extruded aluminum tubing with a thin wall and a round cross section is bent at an acute angle to form a clevis at its upper end and is bent at about a right angle at its lower end to form a foot engaging portion. A hydroforming process forms the walls of the clevis end and the central portion into a rectangular cross section and forces the walls of the lower end together to form a relatively flat, smooth, upper foot engaging surface and an undersurface with longitudinal ribs. Hexagonally configured apertures in opposing walls of the clevis receive a bushing having the same hexagonal configuration. A cut-out section communicates with the aperture in the two opposing walls, and the bushing is secured in the apertures by forcing together the walls adjacent to those with the apertures to close the gap in the cut-out sections.

  • Patent number: 5429174
    Abstract: Vacuum die casting machine including an improved siphon tube for transporting molten metal from a reservoir to a shot cylinder. The siphon tube defines a passageway having a first end portion which is adapted to communicate with a shot cylinder and a second end portion opposite the first end portion which defines a molten metal entry portion. The passageway tapers from the first end portion to the second end portion which reduces jetting in the shot cylinder. An associated method is also disclosed.

  • Patent number: 5386900
    Abstract: An adjustable can conveyor comprises a fixed trackwork assembly and a moveable trackwork assembly. The fixed trackwork assembly includes at least two outer collars, a can guide track and two guide rails. The moveable trackwork assembly includes at least two inner collars, a can guide track and two guide rails. An interlocking mechanism is used to secure the two trackwork assemblies together such that a track able to convey can bodies is created. The locking mechanism is adjustable such that the conveyor may be set up to move cans of varying length. Because of the interlocking mechanism used, the moveable trackwork assembly is completely supported by the fixed trackwork assembly during adjustments. Further, the four guide rails associated with both trackwork assemblies may be rotated in such a manner that allows for adjusting the conveyor for cans of varying diameter.

  • Patent number: 5349839
    Abstract: Disclosed is apparatus and methods for the stretch forming of an elongated hollow metal section, such as an aluminum extrusion. The apparatus and methods use a flexible constraining means which surrounds at least a portion of the outer periphery of the elongated hollow metal section to constrain and support the walls of the elongated hollow metal section against the forces produced within the interior of the hollow metal section during the reshaping of the extrusion by the stretch forming operation. The apparatus and methods disclosed herein resist wrinkles, crimps and bulges being formed in the walls of the elongated hollow metal section during the stretch forming and reshaping thereof.

  • Patent number: 5335532
    Abstract: Both a method and an apparatus for the reduction of the load magnitudes present during the operation of a can body maker apparatus are provided through the use of a counterbalance mass structure system. A counterbalance structure is operatively associated with the crankshaft which motivates the can body maker ram assembly so that as the ram assembly is reciprocated along a straight line path during the formation of can bodies, the counterbalance structure is reciprocated to compensate for both the straight line (X axis) motion of the ram assembly as well as motion perpendicular thereto.

  • Patent number: 5284238
    Abstract: A rolling can conveyor includes an endless belt path and a flexible belt defining a plurality of openings therein for fluid communication therethrough. The flexible belt is operatively associated with the endless belt path such that the flexible belt is vertically oriented for at least a portion of the belt path. The bottom of the can body is held in contact with the flexible belt during transport by negative pressure. A guide rail extends along the vertically disposed flexible belt so as to support the can body. A plenum is operatively associated with the endless path proximate the guide rail. A vacuum is coupled to the plenum for applying a negative pressure sufficient to rotatably retain the can body in contact with the flexible belt and the guide rail, which imparts rotational motion to the can body about its longitudinal axis during transport.

  • Patent number: 5167478
    Abstract: The present invention is a tool holder which permits lateral insertion and removal of a tool means into and from the holder thereby making it unnecessary to move the machine or work piece to provide excess clearance. The tool holder includes a main body having a shallow tool cavity formed in one end thereof for receiving the tool means. A locking element having a u-shaped collar is rotatably mounted to the main body for clamping the tool means within the tool cavity. The u-shaped collar defines a tool slot having a tool slot opening which extends from the side of the locking element. When the locking element is in an unlocked position, the tool slot opening aligns radially with the open side of the tool cavity to permit lateral insertion and removal of the tool means into and from the cavity. When the locking element is rotated to the locked position, tool slot opening is moved out of alignment with the open side of the cavity thereby preventing removal of the to tool means.

  • Patent number: 5109706
    Abstract: A tightening fixture for tightening a lock nut on a chuck including a torque readout device for measuring the torque applied to tighten the lock nut. The tightening fixture includes a stationary support block having a torque transmitting collar rotatively mounted therein. The torque transmitting collar is designed to receive and hold the chuck so that the chuck is held nonrotatable with respect to the collar. When torque is applied to tighten the lock nut on the chuck, the chuck and collar rotate as a unit. A torque indicator is mounted in the stationary block and is responsive to the rotation of the torque transmitting collar to provide an indication of the torque applied to tighten the lock nut.
