触媒コンバータの製造方法
Document Type and Number:
Japanese Patent JP6748992
Kind Code:
B2
Abstract:
To form at least a tapered part on one end part while being appropriately retained in a cylindrical body without allowing an excessive load to be applied onto a catalytic carrier, in a manufacturing method of a catalytic converter which performs press-fitting of a buffer member and the catalytic carrier into the cylindrical body of a non-circular curve cross-section and performs spinning for at least one end part of the cylinder body.SOLUTION: A manufacturing method of a catalytic converter includes a first process (P1) of retaining a main body part (11) of a cylindrical body (W) of a non-circular curve cross-section by means of clamp members (40, 50), a second process (P2) of press-fitting a buffer member (30) and a catalytic carrier (20) into the main body and a third process (P3) of performing spinning for at least one end part of the cylinder body and forming at least a tapered part (12).SELECTED DRAWING: Figure 5
