    • The present invention provides a method for manufacturing a honeycomb structure, the method including steps of: forming, by extrusion, a formed body 1 having an outer wall, partition walls provided inside the outer wall, and cells each surrounded by the partition walls as well as extending to an axial direction of the body; and drying the formed body 1. The method for manufacturing the honeycomb structure is characterized in that the forming step includes receiving the formed body on a cradle 10 which receives the formed body so that an angle of a face 7a of the outer wall on the cradle 10 relative to the horizontal plane is 15 to 35 degrees, a cradle which has a V-shaped cross section with a cut at an apex of the V shape and which receives the formed body so that the angle relative to the horizontal plane is 15 to 45 degrees, or a cradle which receives one face of the formed body and characterized in that the drying step includes drying the formed body 1 in a state of being received on the cradle 10 having the predetermined angle. The method for manufacturing the honeycomb structure reduces distortion and deformation of the honeycomb structure.
    • 本发明提供一种蜂窝结构体的制造方法,该方法包括以下步骤:通过挤压成形成形体1,该成形体1具有外壁,设置在该外壁内侧的隔壁以及被该隔壁包围的单元 如延伸到主体的轴向方向; 以及干燥成形体1.蜂窝结构体的制造方法的特征在于,成形步骤包括将成形体接纳在容纳成形体的托架10上,使得托架上的外壁的面7a的角度 10相对于水平面的角度为15°〜35°,具有V形截面的V形截面的托架,其接收成形体,使得相对于水平面的角度为15°〜 或接收成形体的一个面的托架,其特征在于,干燥步骤包括在容纳在具有预定角度的托架10上的状态下干燥成形体1。 用于制造蜂窝结构的方法减少了蜂窝结构的变形和变形。
