CUTTING DEVICE FOR MOLDING BODIES, CUTTING PROCESS FOR CERAMIC SHAPING BODIES AND METHOD FOR THE PRODUCTION OF A HEAVY-DRAWN STRUCTURED BODY

摘要

It is an object of the present invention to provide a molded body cutting apparatus capable of cutting an extrusion-molded body while preventing deformation of a cut face after cutting and re-adherence of constitution material to the cut face, and the molded body cutting apparatus of the present invention comprises: a first conveyer member that conveys an extrusion-molded pillar-shaped ceramic molded body; a cutting member that moves in a direction parallel to a movement direction of the above mentioned first conveyer member while moving also in a vertical direction, and cuts the above mentioned ceramic molded body to a predetermined length by passing through the interior of the above mentioned ceramic molded body; and a second conveyer member that conveys a cut ceramic molded body cut to a predetermined length by the above mentioned cutting member, wherein a conveyance speed of the above mentioned first conveyer member and a movement speed of the above mentioned cutting member in the above mentioned parallel direction are almost the same, before the above mentioned ceramic molded body is cut, and each of the conveyance speed of the above mentioned first conveyer member, the movement speed of the above mentioned cutting member in the above mentioned parallel direction, and a conveyance speed of the above mentioned second conveyer member becomes faster toward the latter, after the above mentioned ceramic molded body is cut.
