20080216551 | Die Holder Technology for Metal-Fabricating Press - The invention involves a die holder for a press, such as a metal-fabricating press. The die holder can be configured to receive a die, and can include a clamp portion and a wall portion. Preferably, the clamp and wall portions can be positioned in an open configuration or a closed configuration, and the die holder can be adjusted from an unclamped configuration to a clamped configuration. The die holder may have a die-release mechanism useful for overcoming stiction and facilitating removal of the die from the die holder. | 09-11-2008 |
20090007747 | LIVE TOOLING SYSTEMS FOR MACHINE TOOLS - In conventional ram-driven presses, the downward stroke of the ram into a tool causes acceleration of the tool, thereby facilitating an operation on a workpiece by the tip of the tool. While the ram stroke is found to impart sufficient dynamic energy to the tool to facilitate the necessitated operation by the tool tip, there are other more efficient, and in turn, more effective, means and methods of actuating the tool tip, with such means and methods being facilitated from energy derived from the tool's acceleration or from energy from other external sources. | 01-08-2009 |
20090019977 | MULTI-DRIVE TOOLING - The invention involves a multi-drive tool for use on a fabricating press having a table with multiple stations. Each station can include a mount opening passing through the table. The multi-drive tool can have a bridge member relating to at least two drive members such that a ram stroke of the press simultaneously moves the drive members or components thereof in a direction toward the workpiece. The invention also involves a die shoe adapted for use on a press. A die-mounting recess configured to receive a die is formed in the top of the die shoe. The invention also provides a fabricating press in combination with a multi-drive tool, as well as methods of fabricating a workpiece. | 01-22-2009 |
20090320550 | Anti-Vibration Die Holder Technology for Fabricating Press - The invention involves an anti-vibration die holder for a press, such as a metal-fabricating press. The anti-vibration die holder preferably includes at least one resilient surface adapted to contact a die when the die is mounted operatively on the die holder. | 12-31-2009 |
20100064762 | DIE HOLDER TECHNOLOGY FOR FABRICATING PRESS - The invention involves a die holder ( | 03-18-2010 |
20100107846 | PUNCH ASSEMBLIES AND METHODS FOR MODIFYING - A retain-and-release member, which is coupled to a punch holder of a punch assembly, engages a punch tip against an end of the holder, such that a working portion of the tip extends from the end. A punch guide sidewall of the assembly includes an aperture aligned with an actuation interface of the retain-and-release member, when the punch holder and the engaged punch tip are slidably engaged within a guide bore formed by the punch guide sidewall. The aperture provides access for applying a force, to the actuation interface, in order to disengage the retain-and-release member from the punch tip, while the punch holder remains within the guide bore of the assembly. Following the removal, the same punch tip, or another, may be inserted into the guide bore and into engagement with the retain-and-release member. | 05-06-2010 |
