るプレス金型用穴あけ加工装置。This is a device for drilling holes in the side wall of a press work, and includes a hole punch provided on the side wall of the lower mold on which the press work is placed, a punch that can fit into the die, and the punch attached to the front part. A slide cam is formed with upper and lower inclined cam surfaces at the rear thereof and is supported on the side of the lower mold so as to be movable back and forth in opposition to the die, and an upper inclined cam surface at the rear of the slide cam is fixed to the lower surface of the upper mold and is fixed to the lower surface of the upper mold when the upper mold is lowered. A driver cam is formed with a cam surface that contacts the cam surface and moves the slide cam to a machining preparation position close to the workpiece to be pressed, and the driver cam is swingably supported with an axis perpendicular to the punch axis, and is constantly It is urged to swing forward, and is also able to swing backwards by contacting the upper inclined cam surface of the slide cam when the upper mold is lowered, and by contacting the lower inclined cam surface at the rear of the slide cam when the upper mold is rising. A drilling device for press molds, comprising a processing cam formed with a cam surface that moves a slide cam forward during processing.
