Title:
グリーンハニカム成形体の封口用治具及びハニカム構造体の製造方法
Document Type and Number:
Japanese Patent JP5636524
Kind Code:
B2
Abstract:
A closing jig for a green honeycomb molded body includes closing protrusions which are arranged at positions corresponding to regular hexagonal cells and are inserted into the regular hexagonal cells to weld partition walls to each other for closing. Each of the closing protrusions includes a conical tip end portion that has a conical shape, and a triangular pyramidal base portion with a truncated triangular pyramidal shape having an apex angle larger than an apex angle of the conical tip end portion. The conical tip end portion has the conical shape with an acute apex angle, and thus even when positional deviation occurs in the regular hexagonal cells, it is easy to insert the conical tip end portion into each of the regular hexagonal cells. The triangular pyramidal base portion has the truncated triangular pyramidal shape having the large apex angle, and thus it is easier to weld the partition walls to each other by pressing and expanding the partition walls.
