Electrical discharge machine

摘要

An electrical discharge machine including a lower support part (2) provided to a tilt shaft (4) rotatable and extending horizontally and an upper support part (3) provided to a forward/backward shaft (5) extending parallel to the tilt shaft (4) from a support column (42) provided vertically to the tilt shaft (4) and movable forward and backward in the extending direction. The lower support part (2) includes a lower guide roller (21) that rotates in a tilting plane in which the tilt shaft (4), the support column (42), and the forward/backward shaft (5) lie, the upper support part (5) includes an upper guide roller (31) that rotates in the tilting plane in which the tilt shaft (4), the support column (42), and the forward/backward shaft (5) lie, and a wire electrode (1) is suspended around the upper guide roller (31) and the lower guide roller (21).

1. An electrical discharge machine in which a workpiece is arranged while a wire electrode is moved from an upper support part to a lower support part and the workpiece is chipped away by an electric discharge generated between the wire electrode and the workpiece, the electrical discharge machine comprising:
the lower support part provided to a tilt shaft rotatable and extending horizontally; and the upper support part provided to a forward/backward shaft extending parallel to the tilt shaft from a support column provided vertically to the tilt shaft and movable forward and backward in the extending direction, wherein the lower support part includes a lower guide roller that rotates in a tilting plane in which the tilt shaft, the support column, and the forward/backward shaft lie, the upper support part includes an upper guide roller that rotates in the tilting plane in which the tilt shaft, the support column, and the forward/backward shaft lie, the wire electrode is suspended around the upper guide roller and the lower guide roller, and the upper support part includes a swing lever that tilts parallel to the rotation plane of the upper guide roller and is pivotally attached to a rotation shaft of the upper guide roller, a nozzle that supplies liquid of a dielectric to the wire electrode and is provided to one end of the swing lever, and a rod of a cylinder that is pivotally supported to the forward/backward shaft and is pivotally attached to another end of the swinq lever.
