Abstract: A hydro-forming tool for use in a method of forming a blank into a liquid filled chamber. The chamber is formed by a container ring and a moveable wall that together define a variable volume chamber for containing the liquid. The wall is moveable relative to the container ring to provide a chamber in which the volume of liquid required to back up the blank is minimized. The liquid reduces friction at the chamber entry rim. Liquid may be ported through a counter punch to hydro-form the blank into the detail forming areas.

Abstract: A guided keeper assembly for metal forming dies includes a base having a mounting face and a fastener aperture to mount the base to an associated die shoe, as well as a central guide aperture. A guide pin having a central portion is closely received in the central guide aperture for precisely guiding reciprocal motion between the die pad and the die shoe. The guide pin has an enlarged head at one end which abuts the the-base to positively limit travel between the die shoe and the die pad, and a shoulder at an opposite end with an alignment mechanism that precisely locates the guide pin on the die pad. A fastener extends through the fastener aperture in the base to securely connect the same with the die shoe. Another fastener securely connects the second end of the guide pin with the die pad.

Abstract: A guided keeper assembly and method for metal forming dies includes a base having a mounting face, a connector portion and a central aperture. A guide pin has a cylindrical center portion closely received in the central aperture of the base for reciprocation, an enlarged first end with an alignment member, and an outwardly opening circumferential groove. A retainer ring is removably mounted in and protrudes radially outwardly of the groove to securely, yet detachably, retain the base on the guide pin between the enlarged head and the retainer ring in an assembled condition to facilitate transport and mounting of the guided keeper assembly.

Abstract: A press frame for attaching connectors to workpieces such as cables and pipes is described. The press frame is adapted to be releasably attached to a hand-held, battery powered press tool. The press frame includes selectively interchangeable components that enable a wide range of different styles, sizes, and configurations of electrical connectors to be attached to cables.

Abstract: A guided keeper assembly and method for metal forming dies includes a base having a flat mounting face and at least one marginal fastener aperture to detachably mount the base to an associated die shoe, as well as a central guide aperture. The assembly also includes a guide pin having a central portion closely received in the central guide aperture of the base for precisely guiding reciprocal motion between the die pad and an associated die shoe. The guide pin has an enlarged head at a first end thereof which abuts the mounting face of the base to positively limit travel between the die shoe and the die pad, and a shoulder at the opposite or second end thereof with an alignment mechanism that precisely locates the second end of the guide pin on the die pad. A first fastener extends through the marginal fastener aperture in the base to securely, yet detachably, connect the same with the die shoe. A second fastener securely, yet detachably, connects the second end of the guide pin with the die pad.

Abstract: In a deep drawing method, a sheet metal blank is positioned between two dies of a deep drawing machine and then shaped into a hollow article, whereby the dies, at least during a partial stroke phase, undergo a controlled non-rectilinear relative movement and one of the dies is shifted by a transverse displacement mechanism in a direction transversely to a stroke direction.

Abstract: The invention relates to an expansion tool for expanding tube ends. The expansion tool has an expansion mandrel and a counter-support, said expansion mandrel consisting of a tow-bar and an elastic rubber expansion element surrounding it. The counter-support supports the expansion element on the base extremity and radially surrounds it at a distance. In order to improve an expansion tool of the above-described kind, the tow-bar is anchored in a bolt fastening element and the counter-support can be impinged upon via a pressure bar element that projects beyond the bolt fastening element in the longitudinal direction of the tow-bar.
