Abstract
PURPOSE: To smoothly operate a punching press, etc., and to prevent a metallic sheet from being stained by oil, by providing an oil reserving cavity in a stripper made of an elastic material in order to supply the oil to the punch surface when a press goes down, and by providing an oil drop retainer in the stripper.
CONSTITUTION: A stripper 2 surrounding a punch 3 is made of an elastic material, and a cavity 6 is provided within the thick wall of this elastic stripper 2. An oil charging pathway 7 provided with a check valve 8 and an oil discharging pathway 7' opening on the punch 3 side are communicated with this cavity 6. The lubricant, etc., is reserved in the cavity 6. When a press 1 goes down, the stripper 2 causes an elastic deformation so that the oil is ejected through the oil discharging pathway 7' against the outer wall surface of the punch 3. The oil drop fallen from the oil discharging pathway 7' is caught by an oil drop retainer 9 provided in the inner surface of the lower end on the punch 3 side of the stripper 2 so that the dropping of the oil upon a metallic sheet 5 is prevented. By the present mechanism, the outer wall surface of the punch 3 is finely lubricated, so that the withdrawing action of the punch 3 is smoothly practiced.
