Title:
METHOD FOR PRODUCING HONEYCOMB STRUCTURE, APPARATUS FOR WORKING GREEN HONEYCOMB MOLDING, AND HONEYCOMB STRUCTURE
Document Type and Number:
Japanese Patent JP2014141063
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a honeycomb structure, in which cutting stock is hardly generated by cutting work or the like, additional materials are not required and an excellently worked plane can be obtained, and to provide an apparatus for working a green honeycomb molding and the honeycomb structure.SOLUTION: The green honeycomb molding 70 is obtained by opening a plurality of through-holes, the adjacent ones of which are divided from each other by a partition wall, on the end face of a columnar body, The green honeycomb molding 70 is worked by applying an ultrasonic wave locally to the green honeycomb molding 70 to locally liquefy the green honeycomb molding 70. As a result, the cutting stock is hardly generated by cutting work or the like and the production yield can be improved. Moreover, since the worked plane is hardly fluffed, the worked plane can be made excellent.
