摘要： PROBLEM TO BE SOLVED: To provide a press drive mechanism which has a simple structure without using a multi crankshaft and small rotational inertia force in a drive mechanism of a press having opposing slides. SOLUTION: Each slide moves toward or apart from the other slides by containing the press having two slides 14, 20 arranged opposingly each other, by connecting a single crankshaft 16 to each slide, and by rotation of the crankshaft. The drive mechanism is arranged under two slides and protected from oil leakage. A dynamic balancer is used so as to substantially balance press inertia force during operation, and as a result, 90% or more of the press inertial force in the vertical direction is balanced. The press can be stopped during within one rotation of the crankshaft by balancing the press inertia force in such a manner. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a press, to which a quick die opening device capable of executing a stable pressing and of immediate movement of a slide is attached. SOLUTION: This press P is provided with a slide 3, which is arranged so as to vertically move in the upper side of a machine frame 1, the slide 3 is stroke moved by a first slide driving part 10, and openings of the slide 3 and a bolster 4 are constituted to be widened by largely moving the slide 3 upward by a second slide driving part 20. A toggle mechanism is adopted in the first slide driving part 10, a cylinder body 25 which is composed of a piston part and an outer casing sliding relative to the piston part is disposed in the second slide driving part 20, and a hydraulic chamber and air pressure chamber are formed in the cylinder body 25.

摘要： PROBLEM TO BE SOLVED: To provide a press working method to enable precision working by reducing impact force on colliding at a work so as to reduce breakthrough, to increase a die life by reducing wear/breaking of a punch and to reduce working noise and vibration by extremely reducing impact noise at the time of particularly conducting bottoming, coining or drawing, etc. SOLUTION: This working method is to control, when descending a slide of a press machine from a top dead center position to a bottom dead center position so as to extremely slowly descend the slide near the bottom dead center and rapidly from the bottom dead center neighborhood to the bottom dead center position. Accordingly, a process curve is formed so as to protrude downward from the bottom dead center neighborhood to the bottom dead center position. Further, the slide is driven by a servo motor, a linear motor as well as a cam means, etc.

摘要： PCT No. PCT/GB93/00548 Sec. 371 Date Sep. 26, 1994 Sec. 102(e) Date Sep. 26, 1994 PCT Filed Mar. 17, 1993 PCT Pub. No. WO93/18878 PCT Pub. Date Sep. 30, 1993A method and apparatus for manufacturing a powder metallurgy article comprising two or more individually compacted layers is described. The apparatus includes a number of powder deposition means for depositing powder into at least one die cavity, the number of powder deposition means corresponding to at least the number of different powder compositions in an article being compacted, a die assembly having a female die body which is moveable with respect to a first press ram, a mechanically driven second press ram, means for driving said second press ram, control system means for controlling the relative positions and movements of said female die body, said first press ram, said second mechanically driven press ram and said powder deposition means such that they operate in synchronism, characterised by said control system means including an angle counter having proportional drive means from the press apparatus such that one cycle of the angle counter corresponds to a required number of press compaction strokes.
