SOUND ABSORPTION BOARD MANUFACTURING DEVICE AND METHOD WHICH FORM A SOUND ABSORPTION GROOVE INSIDE A SOUND ABSORPTION BOARD

摘要

PURPOSE: A sound absorption board manufacturing device and method are provided to efficiently form a sound absorption groove in a sound absorption board of organic composite material using three vertical cutting blades and one horizontal cutting blade.;CONSTITUTION: A sound absorption board manufacturing device comprises a base frame(100), a transfer unit, a vertical blade unit(300), a horizontal blade unit(500), a vertical blade driving unit(400), and a horizontal blade driving unit(600). The transfer unit linearly moves a sound absorption board(P) on the base frame in a specific direction. The vertical blade unit comprises three disk type vertical cutting blades(310) and forms a vertical cutting line(L1) to form a sound absorption groove inside the sound absorption board. The horizontal blade unit comprises one disk type horizontal cutting blade(510) and forms a horizontal cutting line(L2) to form a sound absorption groove inside the sound absorption board.;COPYRIGHT KIPO 2012
