摘要： For producing stamped parts, especially plates, a method is proposed consisting of only two method steps. In a first method step the workpiece is fine blanked (2) inside a device (1) is then moved to a stamping stage (3) by means of transfer tongs (4) which are likewise housed in the device (1). The stamping stage (3) is also located inside the device (1). In a second method step, the inner and outer contours are stamped on the workpiece (5) in the stamping stage (3) in a manner such that the burrs produced on the workpiece (5) during the first step are removed.

摘要： A workpiece blanking apparatus has a die, a pad for holding a plate of metal on the die, a blanking punch for depressing the plate on the die downwardly of the die to blank a workpiece out of the plate, and a counterpunch vertically movably disposed in the die in confronting relationship to the blanking punch and movable downwardly with the workpiece blanked by the blanking punch. A counterpunch urging device normally urges the counterpunch upwardly, and a holding mechanism holds the counterpunch in a lowered position after the workpiece is blanked by the blanking punch until the blanking punch is spaced from the workpiece, the pad is spaced from the plate, and the blanking punch and the pad are lifted to a predetermined position. The holding mechanism releases the counterpunch in the lowered position and allows the counterpunch to displace the workpiece out of the die when the blanking punch and the pad are lifted to the predetermined position.

摘要： A method for manufacturing a metal part and a sheet pressing wheel, in which reduction of their manufacturing cost is intended by enabling them to be formed only by plastic work such as press-work even if they are very small; and a printer in which such wheels are incorporated as a sheet feed mechanism. In the method for manufacturing a metal part, plastic work is given to a metal plate to thereby manufacture the metal part. The method for manufacturing a metal part comprises a first forming step for performing a punching work for roughly forming at least a part of the outline shape of the metal part; a second forming step for giving a face-pressing work to at least an outline edge portion of the metal part to thereby thin the outline edge portion; and a third forming step for shaping the outline shape again by a punching work.

摘要： A hub lock releasing structure for a tape recorder has a releasing pin for releasing a hub from a locked state by pressing a hub locking member installed on a tape cassette in one direction as the tape cassette settles on a deck. The releasing pin is integrally formed with the deck. In the hub lock releasing structure, since the releasing pin is integrally formed with the deck, the number of necessary components can be reduced and the assembly process can be simplified. A method of fabricating a releasing pin for the hub lock releasing structure comprises providing a deck in the tape recorder for receiving a tape cassette, partially cutting a portion of the deck, and bending the cut portion of the deck upward to form the releasing pin.

摘要： A package for receiving electronic parts is formed with decreased stress and stress concentration to obtain a desired warp and flatness. In particular, according to a cutting protruding part process, a package is accommodated to have a recessed part formed on one face of a metal plate by pressing the face of the metal plate so that a corresponding protruding part is formed bulging from an opposing face of the metal plate. The protruding part is cut by a cutting tool and a bottom which has a cavity shape and is thinner in size than the metal plate is formed at the recessed part. The protruding part is again formed bulging from the metal plate and cut by the cutting tool. The cutting direction is differed in alternately facing directions so that the stress from cutting is almost cancelled.
