Abstract
Apparatus for forming a honeycomb structure capable of adjusting a shaping speed of an outer skin of the honeycomb structure, thereby preventing a defect in the skin. The shaping device is constructed by a die (10) having slits (11) for formation of a honeycomb structure and a guide ring (2) arranged downstream of the die (11). The guide ring includes an opening with an inner edge (21) and includes at a location upstream from the edge a pool portion (22) for the formation of a skin of the honeycomb structure. A temperature controller (3) is arranged in the guide ring for controlling a heating on a cooling of a ceramic material held in the pool portion (22).
Claims7
An apparatus for shaping a honeycomb structure from a material, comprising:
- a die including a plurality of slits through which the material is flown for creating the honeycomb structure;
- a guide ring arranged at a location downstream from the die, said guide ring having an inner opening having an edge for restricting the outer diameter of a product, while forming a pool portion on one side of the edge adjacent the die for a formation of a skin portion of the honeycomb structure, and;
- a temperature controller arranged at the guide ring for obtaining an adjustment of the temperature of the guide ring.
