Patent number: 7326008Abstract: A servo motor in die tapping unit provides built in shock protection for the motor by fixing a shock plate to the servo motor and floatingly mounting the shock plate to a base structure attachable to a stripper plate in a press. Sets of opposing springs allow movement of the shock plate relative the base plate to relieve shock loads when the press is operated, the shock plate guided on dowel pins fixed to the base structure. The shock plate, and tapping unit and base structure form a self contained assembly for mounting together in the press.Type: GrantFiled: December 10, 2004Date of Patent: February 5, 2008Assignee: Danly IEM, LLCInventors: Victor L. Chun, Frank Madej, Alexander B. Leibman

Patent number: 7191635Abstract: A press mounted cam has a slide guided on an adapter by structural features including as one or more T blocks fixed to the slide and received in a respective channel formed in the adapter. In an aerial cam embodiment, a vertical clearance space is provided between the T block and adapter channel such that positive driving engagement between cam surfaces on the slide and the adapter is momentarily delayed after the initial engagement of the slide and driver surfaces to let the momentum of the slide be absorbed prior to the beginning of positive driving by the press motion, reducing shock and noise. The slide is laterally located with respect to the driver by an upwardly projecting locator-guide key on the driver received in a central channel in the slide. A positive return is provided by engagement of a driver key having T features received in a T-shaped slide channel and captured therein when the slide is driven laterally.Type: GrantFiled: February 28, 2005Date of Patent: March 20, 2007Assignee: Danly IEM, LLCInventors: Victor L. Chun, Brian Russel, Brian Lee Taylor, Frank Madej

Patent number: 7192223Abstract: A servo motor driven tapping unit for in die installation has a tap holder pitch adapter assembly mounted for removal while the unit is in the die to facilitate tap and pitch adapter replacement. In one embodiment, the tap holder pitch adapter assembly extends transversely to the servo motor axis, and is offset in another embodiment.Type: GrantFiled: April 15, 2003Date of Patent: March 20, 2007Assignee: Danly IEM, LLCInventors: Victor Chun, Michael Hajjar, Frank Madej, Alexander B.

Publication number: 20070059093Abstract: A flange is formed on demountable pin and bushing guide elements made to order by assembling one or more separate pieces onto stock cut lengths to form ordered flanged pins or bushings. The flange can be formed by assembling a plurality of partially annular pieces into a reduced diameter groove in said pin, and an outer ring is press fit over the assembled pieces. The outer diameter formed by the assembled partially annular pieces is shallowly tapered and fit to a tapered inner diameter of the outer ring. The flange may alternatively be formed by shrink fitting a ring onto a cut length at a location between two shoulders machined into the element or by separate fixturing engaging the ring to accurately control the location and orientation of the flange.Type: ApplicationFiled: September 9, 2005Publication date: March 15, 2007Inventors: Victor Chun, Frank Madej

Patent number: 7134313Abstract: A tool mounting and method for adjustably mounting a tool holder on a cam slide of a press mounted cam also including an adapter body and driver. The tool mounting includes a tooling plate adjustably secured to the cam slide by a series of dowel pins closely fit in dowel pin openings in the cam slide and loosely fit in dowel pin holes in the tooling plate to allow vertical and horizontal adjustment. A channel extends to each oversized dowel pin opening to enable injection of a setting material to lock the tooling plate in its adjusted position after being aligned with a die opening using a pilot installed in a tool holder mounted on one side of the tooling plate. An alignment plate is installed over the other side to cover the channel to each oversized dowel pin hole and allow removal and replacement of the tooling plate without disturbing the adjusted position on the tooling plates.Type: GrantFiled: December 30, 2004Date of Patent: November 14, 2006Assignee: Danly IEM, LLCInventors: Victor L. Chun, Frank Madej, Jordan Owens

Publication number: 20060071001Abstract: A removable closure for blocking an opening able to resist high forces is formed by a plug assembly installed in a receptacle located over the opening, the receptacle including a smaller bore at the beginning of the receptacle and a larger bore adjacent thereto, these bores together forming an inwardly extending rim and an adjacent groove, with opposite radial clearance openings extending axially through the rim. The plug assembly includes two oblong plates mounted on a plug member, a first oblong plate threaded onto an intermediate threaded section of the plug member, a second oblong plate fixed to the end of the plug next to the first oblong plate in a crosswise orientation. The plug member is rotated to align the two oblong plates in preparation for insertion into the receptacle, and the ends thereof are then inserted into the clearance openings to position the second oblong plate entirely within the groove while leaving the first oblong plate ends interfit within the clearance openings.Type: ApplicationFiled: September 29, 2004Publication date: April 6, 2006Inventors: Victor Chun, Frank Madej

Patent number: 6547496Abstract: An in-die tapping unit for a press in which two ball screw mechanisms are driven by closing motion between two housing pieces caused by press actuation. Both ball screw mechanisms rotate a central drive gear which causes rotation and axial advance of a pitch adapter sleeve axially advanced by a threaded engagement with a fixed pitch adapter hub, the movable pitch adapter carrying a tap holder, which rotates and advances a tap inserted therein. A striker pad and acceleration spring reduces the shock loading of the unit when the press engages the upper housing piece.Type: GrantFiled: July 27, 2001Date of Patent: April 15, 2003Assignee: Danly IEM, division of Connell Limited PartnershipInventors: Victor Chun, Michael Hajjar, Frank Madej
