Abstract
A ceramic catalyst carrier 6 with a non-expandable mat 7 being assembled on an outer periphery thereof is, after the entire outer peripheral surface of the non-expandable mat 7 is evenly pressed in a radial direction and an contour thereof is press formed to be close to an inner diameter of an outer housing cylinder 8 constituting a part of an exhaust passage, press-fitted into the outer housing cylinder 8 by a press-fitting unit 3.
Claims11
A press-fitting method for press-fitting a ceramic catalyst carrier with a non-expandable mat being wrapped thereon into an outer housing cylinder, wherein the ceramic catalyst carrier with the non-expandable mat being assembled on an outer periphery thereof is, after an entire outer peripheral surface of the non-expandable mat is evenly pressed in a radial direction and an contour of the non-expandable mat is press formed to be close to an inner diameter of an outer housing cylinder constituting a part of an exhaust passage, press-fitted into the outer housing cylinder.
A press-fitting apparatus for press-fitting a ceramic catalyst carrier with a non-expandable mat being wrapped thereon into an outer housing cylinder, comprising:
- a press-forming jig configured to evenly press in a radial direction an entire outer peripheral surface of a non-expandable mat assembled on an outer periphery of the ceramic catalyst carrier and press form an contour of the non-expandable mat to be close to an inner diameter of an outer housing cylinder constituting a part of an exhaust passage;
- and a press-fitting unit configured to press-fit the ceramic catalyst carrier with the non-expandable mat being press formed by said press-forming jig into the outer housing cylinder.
