Vibration finish punching method
专利汇可以提供Vibration finish punching method专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a high productivity in finishing the inside wall surface of a hole subsequently to a punching operation by combining a vibration action with shearing, in the case of punching a hole in a plate material or the like.
CONSTITUTION: When punching by a press a composite material comprised of a matrix of a resin reinforced with fibers, the plate material 1 to be punched for forming a hole is inserted between dies 2, 3 through an access hole 21a of a container 21, and punches 6, 7 are advanced under the condition where the plate material 1 is clamped by a die presser 2, the plate material 1 being clamped by a pressing means 24' as required. On the other hand, a controlling system sets a frequency, a loading period, an amplitude of vibration and the like in accordance with the thickness and the material of the plate, and operates a vibration loading device 24. Accordingly, the mutual friction of a punched scrap part and the inside wall 13 of the hole and the shaving of the inside wall 13 by the upper and lower punches 6, 7 are repeated, and a varnish finishing of the inside wall 13 of the hole is conducted.
