Abstract
Provided is a power supply unit, which is to be used for a multi-wire electrical discharge machining apparatus arranged to slice a material to be machined by an electrical discharge generated between a wire group including a plurality of turns of a wire arranged in parallel and the material to be machined, and to which a power supply terminal to be brought into contact with the wire group at a time to supply a voltage to the wire group is mounted, the power supply unit including: a mounting portion to which the power supply terminal to be brought into contact with the wire group at a time is mounted; and an adjusting portion arranged to adjust an inclination of the mounting portion in a direction crossing a running direction of the wire group.
Claims13
A power supply unit, which is to be used for a multi-wire electrical discharge machining apparatus arranged to slice a material to be machined by collectively bringing a side surface of a power supply terminal having a columnar shape or a cylindrical shape into contact with a wire group in which a plurality of turns of a wire arranged in parallel with intervals to generate an electrical discharge between the wire group and the material to be machined, the power supply unit comprising:
- the power supply terminal having the columnar shape or the cylindrical shape;
- a power supply terminal fixing block to which the power supply terminal is mounted and fixed, the power supply terminal fixing block arranged to extend along the axis of the power supply terminal at a side of the power supply terminal;
- a plate arranged to support a surface of the power supply terminal fixing block opposite from a surface of the power supply terminal fixing block on which the power supply terminal is mounted, the plate being arranged to extend along the direction in which the power supply terminal fixing block extends at a side of the power supply terminal fixing block;
- a fastening portion provided between the power supply terminal fixing block and the plate so as to fasten the power supply terminal fixing block and the plate;
- and
- an axial direction adjuster provided at a position between the power supply terminal fixing block and the plate, the position where the axial direction adjuster is provided being shifted from a position where the fastening portion is provided in the axial direction of the power supply terminal,
- wherein:
- the power supply terminal and the power supply terminal fixing block are provided between the wire group and the plate,
- the power supply terminal is provided between the wire group and the power supply terminal fixing block;
- and
- the axial direction adjuster moves the power supply terminal fixing block upwardly or downwardly against the plate at the position where the axial direction adjuster is provided, thereby a gap between the power supply terminal fixing block and the plate at the position where the axial direction adjuster is provided is made longer or shorter than a gap between the power supply terminal fixing block and the plate at the position where the fastening portion is provided.
