MANUFACTURING METHOD OF HONEY-COMB COMPACT AND MANUFACTURING APPARATUS OF HONEY-COMB COMPACT

摘要

PROBLEM TO BE SOLVED: To sufficiently suppress a honey-comb compact extruded from an extruder from deforming.;SOLUTION: A manufacturing method of a honey-comb compact includes a step of continuously extruding a honey-comb compact from a die of an extruder, a step of supporting a lower side surface of the honey-comb compact extruded from the die by an upper surface of a trough part fixed to the die, and a step of contacting a pedestal to a lower surface of a part that exceeds an apex of the trough in the honeycomb compact, followed by repeating moving the pedestal in the extruding direction, and supporting the part of the honeycomb compact by a plurality of the pedestals. A manufacturing method of a honeycomb compact in which an end part on an opposite side from the extruding direction of the trough comes into contact with the die, when a distance from the die of the extruder to the apex of the trough is regarded as Lf, a length in the extruding direction in the pedestal is regarded as Ls, and a distance from the die of the extruder when the pedestal comes into contact with a lower surface of the honeycomb compact to the pedestal is regarded as Lg, LsLf≥Lg is satisfied.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2017,JPO&INPIT
