Abstract

PURPOSE: To save degreasing process of lubricant on blank surface by providing oil wells at the outside circumference of the punches.
CONSTITUTION: Oil wells 9 are provided around the punch holes of a stripper 5. Next, a cover 10 which is provided with holes corresponding to punches 3 and pilot punch 3a is screwed to a stripper 5. When lubricating oil is filled in the oil wells 9, it reduces the friction resistance between the outside circumference of the punches and blanking blank at the time when the punches 3 move vertically in the stripper holes. As a result, springs 4 can be those of the same strength as that of ordianry ones even without coating any lubricating material and the disengagement from the punches 3 and blank becomes easy. The use of oil of high viscosity in the oil wells 9 eliminates the need for replenishing the oil during the work. To replenish the oil, the cover 10 is removed or an oil feed port is beforehand provided to the cover 10. To use oil of low viscosity, brushes 11 are mounted to the inside surfaces of the punch holes and lubricating oil is coated to the punches 3.
