Publication number: 20100064907Abstract: The invention provides a die changing method of a press machine which can drastically shorten a time required for changing the die. In a press machine (a servo driving type press machine) capable of positioning a slide at an arbitrary position by controlling a servo motor, a time required for moving the slide is shortened by moving the slide in a range necessary for changing the die. Further, it is possible to omit an operation of a slide adjusting mechanism by controlling the servo motor so as to position and control the slide without operating the slide adjusting mechanism, and moving the slide at a height suitable for changing the die, thereby quickening a die changing work.Type: ApplicationFiled: July 20, 2007Publication date: March 18, 2010Applicant: IHI CORPORATIONInventor: Motonao Niizuma

Patent number: 6539853Abstract: A press that includes a push rod (12) that can be pushed downward to cut and mold miniature components, has a small size and a minimum number of components, and can be easily and precisely controlled. The push rod has a largely upwardly-facing shoulder (140) that lies in a chamber that can receive pressured hydraulic fluid to push down the push rod. A piezoelectric actuator, or piezoactor (18), moves a piston (20) that lies in a pressure cylinder. One end of the pressure cylinder holds hydraulic fluid (130), and when the piezoactor pushes the piston it pressurizes the hydraulic fluid therein. Pressured hydraulic fluid in the pressure cylinder flows through a passage (23) to the rod chamber to press down the push rod. The cross-sectional area of the pressure cylinder is many times greater than the cross-sectional area of the push rod shoulder so slight movement of the piezoactor is magnified many times by the hydraulic fluid to move the push rod with a long stroke.Type: GrantFiled: November 3, 2000Date of Patent: April 1, 2003Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Achim Hess, Martin Gollhofer, Klaus Siegert

Patent number: 6186061Abstract: A plurality of hydrostatic bearing pads are each integrally formed in a respective pin or journal member being used within a mechanical press machine. The hydrostatic bearing pads are supplied with pressurized fluid sufficient to create a combined hydrostatic and hydrodynamic effect between the opposed bearing surfaces of the pin and an associated bushing. The hydrostatic bearing pads are used in conjunction with rotational and oscillating bearings in which relatively little rotation, oscillation, or slow rotational speeds exist or where it is desired to minimize the effects of hydrodynamic action which creates bearing “lift off” on journal bearings. These types of bearings are particularly associated with crankshaft and connection journal bearings, connection pins, and pivot pins used by a rocker-type coupling assembly that couples a weight assembly to the press machine piston or slide assembly or drive assembly.Type: GrantFiled: May 11, 1999Date of Patent: February 13, 2001Assignee: The Minster Machine CompanyInventors: Bradley A.

Patent number: 4706532Abstract: The cutting apparatus with rules comprises a cutting form placed in an upper panel support (5) and a lower panel. The panel support (5) is constructed in a fashion enabling it to be withdrawn from the apparatus for purposes of replacing it. The replacement cutting form, supported in another panel support (5) previously prepared, is placed on the lower guides (19) of an adjustment table (14). The adjustment table (14) is brought up against the guides (4) which support the panel support (5) to be replaced in the machine. The latter is withdrawn from the machine so as to come to rest on the upper guides (19) of the adjustment table (14). This pivots by 180.degree. and the replacement cutting form is pushed onto the guides 4 situated in the cutting station.Type: GrantFiled: April 17, 1986Date of Patent: November 17, 1987Inventor: Osamu Hashimoto
