Abstract:
1. A machining oil applying apparatus that applies machining oil onto a thin plate made of metal that is to be supplied to a press apparatus and is being conveyed toward the press apparatus, the machining oil applying apparatus comprising: an upper surface applying unit that is impregnated with the machining oil, contacts an upper surface of the thin plate and applies the machining oil onto the upper surface of the thin plate; a lower surface applying unit that is impregnated with the machining oil, contacts a lower surface of the thin plate and applies the machining oil onto the lower surface of the thin plate; and an applying unit moving portion that causes the upper surface applying unit and the lower surface applying unit to move reciprocally in a direction that is perpendicular to a conveying direction of the thin plate, wherein the applying unit moving portion comprises: a rotational shaft being extended in the vertical direction: a motor for rotating the rotational shaft; and two eccentric cams that are attached onto the rotational shaft, the rotational shaft passes through and is fixed to the eccentric cams at positions that are predetermined distances from centers of circles respectively, the fixed positions of the two eccentric cams, where the rotational shaft is fixed, are positioned with point symmetry with respect to the rotational shaft when viewed from above, the upper eccentric cam of the two eccentric cams is disposed in a cam hole of an upper cam guide place, cam guide plate, the lower eccentric cam thereof is disposed in a cam hole of a lower cam guide plate, one end of the upper cam guide plate is fixed to an upper plate, on which the upper surface applying unit is provided, one end of the lower cam guide plate is fixed to a lower plate, on which the lower surface applying unit is provided, and since the center positions of the two eccentric cams fixed to the rotational shaft are positioned with point symmetry with respect to the rotational shaft, the movement of the upper cam guide plate and the lower cam guide plate caused by the rotation of the rotational shaft, in a direction perpendicular to the conveying direction of the thin plate, is always in opposite directions, thereby the upper surface applying unit and the lower surface applying unit always reciprocate with opposite phase.
