プレス加工の金型、プレス加工装置およびプレス加工の金型のパンチ
Document Type and Number:
Japanese Patent JP7273528
Kind Code:
B2
Abstract:
To make it possible to transmit vibration more easily with a simpler configuration by further reducing processing shape constraints.SOLUTION: A processing end, which is an end on a side pressing a material as an object to be pressed in a first direction when performing press processing, an excitation end, which is an end opposite to the processing end and to which an oscillator is fixed and oscillation is added, and two recesses of a same shape, which are so provided on a side face, which is a face between the processing end and the excitation end, as to face each other in such a manner as to be apart from each other in a second direction orthogonal to the first direction by only a prescribed distance, are formed on a punch. The oscillator is installed at the excitation end, and adds oscillation to the excitation end. A support member is formed into a shape corresponding to each recess, is fitted into each recess, and transmits a first direction force to the punch.SELECTED DRAWING: Figure 1
