Abstract:
Bei einem Verfahren zum Schneiden einer nutförmigen Ausnehmung (40) in ein Werkstück (6) wird ein Schneidwerkzeug (4) für eine Werkzeugmaschine (1) an einem Werkstück (6) bereitgestellt. Das Schneidwerkzeug (4) wird in eine Schneidposition verlagert, in der das Schneidwerkzeug (4) in Eingriff mit dem Werkstück (6) steht. Das in Eingriff mit dem Werkstück (6) stehende Schneidwerkzeug (4) wird zum Schneiden der nutförmigen Ausnehmung (40) relativ zu dem Werkstück (6) verlagert. Beim Schneiden wird ein Span mit einer vorbestimmten, maximalen Spanlänge erzeugt, die geringer ist als eine Gesamtlänge (41) der zu erzeugenden Ausnehmung (40).
Abstract:
A first step of setting a steel material heated to a temperature not lower than an A 1 transformation point on a forming table and a second step of punching a ring-form member from the steel material and thereafter forming and quenching the ring-form member on the forming table are included. A press die (30) is constructed to be dividable into an inner cylinder (30B) and an outer cylinder (30A). In the second step, the ring-form member (2A) is punched from a coil material (2) by pressing a tip end portion of the inner cylinder (30B) and a tip end portion of the outer cylinder (30A) against the coil material (2). The punched ring-form member (2A) is formed and quenched by further pressing a tip end of the inner cylinder (30B) against the ring-form member (2A) while the ring-form member (2A) is held between the outer cylinder (30A) and a forming die (32). A method of manufacturing a rolling bearing ring which achieves a shortened manufacturing process while accuracy in forming of the rolling bearing ring is satisfactorily maintained is thus provided.
Abstract:
There is provided a buildup device (1) that builds up a plate-shaped core after rotating the core by a predetermined angle, and that includes a servomotor (11), a damping plate (25) attached to the servomotor, at least one upper plate (21) provided above the damping plate, at least one lower plate (22) provided below the damping plate, and a plurality of vibration absorbing members (31) attached to the damping plate. The upper plate and the lower plate restrict a degree of freedom of vibration to one direction, and the vibration absorbing members absorb vertical vibration.
Abstract:
The present invention is directed to a method of producing cutlery and a blanking tool to be used in said method of producing cutlery. In the method a sheet metal is placed on a die. The sheet metal is held fixed on the die by means of a holder. In a blanking stroke a punch cooperates with the die to form at least a part of a circumference of a cutlery blank in the sheet metal while the holder holds the sheet metal fixed on the die. Thereafter the sheet metal is released from the die. The blanking tool comprises an upper part in the form of a punch, an intermediate part in the form of a holder and a lower part in the form of a die. The blanking tool further comprises means to move the punch and the holder together as one unit towards the die during a first part of a blanking stroke for the punch. The punching tool comprises means to move the punch in relation to the holder during a second part of the blanking stroke for the punch. The holder abuts the sheet metal placed on the die during said second part of the blanking stroke for the punch.

Abstract:
To provide a stacking apparatus and a stack manufacturing system having high accuracy and productivity. A stacking apparatus 10 includes: a stage unit 4 on which a material to be stacked 90 is placed; a sandwiching member 11 that is vertically movable with respect to the stage unit 4, and between which and the stage unit 4 the material to be stacked 90 is sandwiched; a press member 13 that is vertically movable with respect to the sandwiching member 11 and presses the material to be stacked 90; and a guide pin 14 that guides a stack 91a pressed and stamped out of the material to be stacked 90 by the press member 13.
Abstract:
A solar collector array is disclosed. The array has a plurality of thin walled dishes interconnected by unitary webbing. The dishes and the webbing are formed from a single metallic sheet. Each dish is pressed into a symmetric parabolic surface that concentrates incident light to a position in front of the dish.
