Title:
延性金属製部品の破断面処理方法及び破断面処理装置並びに破断されかつ破断面の処理された延性金属製部品の製造方法及び製造装置
Document Type and Number:
Japanese Patent JP4451151
Kind Code:
B2
Abstract:
A fracture surface treatment method of a fractured ductile metal part for treating fracture surfaces 51a and 52a of the ductile metal part 50, said fracture surfaces 51a and 52a being fracture surfaces obtained by a fracturing operation of fitting halved mandrel portions into a penetrative bore of the ductile metal part having the penetrative bore and driving a wedge in between the halved mandrel portions, said fracture surface treatment method holding said fractured ductile metal part 50 in a state where said fracture surfaces 51a and 52a are separated from each other so as to keep a certain space between them, applying a specified vibration to at least one of said fractured ductile metal part portions in a direction intersecting the direction of fracture and removing fracture powder 59 stuck on said fracture surfaces 51a and 52a, and thereby enabling the optimum face fitting operation in case of fitting again the fracture surfaces of the fractured ductile metal part to each other.
