Title: Method and machine for forming cup-shaped metal parts
Inventor: ITO NORIO
IPC: B21D22/30
Filed: 2000-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a method and a machine for forming cup-shaped metal parts of which bottom face can be made thin with a small processing load. SOLUTION: The processing section of a forming machine 1 is provided with a die 2, a punch 5 and a counter-punch 6. A blank 4 placed atop the die 2 is pushed into the hole of the die 2 by the punch 5 so as to be deep-drawn and ironed. At the same time the counter-punch 6 controlled by an un-illustrated controller partially compresses the bottom face 4b of the blank 4 from below the blank 4. As tensile stress takes place in the bottom face 4b owing to the deep-drawing and ironing processes, the bottom face 4b can be formed thin with relatively small force.

IPC: H01L21/60
Filed: 2000-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a control method of a wire clamp mechanism in a wire bonding apparatus wherein no fault is generated even when operating at a high speed the wire clamp mechanism. SOLUTION: In the control of the wire clamp mechanism for clamping a wire supplied to a capillary tool of the wire bonding apparatus, the wire is clamped by driving with a voice-coil motor in a closing/opening way a clamp- arm mechanism for sandwiching the wire. In the case of this clamping, the clamp-arm mechanism is subjected to its closing operation by driving the voice- coil motor in its closing direction with a clamp-current I2 larger than a clamping-current I1 corresponding to a predetermined clamp load. Then, by driving the voice-coil motor with a (-) current I3 in its opening direction, its closing is decelerated. After the deceleration of its closing, the sandwiching of the wire is performed with a predetermined clamp load by driving the voice- coil motor with the clamp-current I1.  As a result, the shock given to the wire when clamping the wire can be relaxed without delaying the contact time of the wire clamp mechanism.
