Title:
CUTTING TOOL FOR FORGING
Document Type and Number:
WIPO Patent Application WO/2021/162162
Kind Code:
A1
Abstract:
The present invention relates to a cutting tool for forging and, more particularly, to a cutting tool in which a cutting blade can be replaced by simply attaching and detaching a fixed block to/from a blade holder, which can secure the quickness, convenience, and reliability of coupling between the blade holder and the cutting blade, and a consistency of a coupling position of the cutting blade, and in which the coupling state and the coupling position of the cutting blade do not change even if physical impact is applied to the cutting blade after the cutting blade is coupled. Accordingly, the present invention may provide a cutting tool for forging comprising: a blade holder having a protrusion formed on one side of a central seating groove, a fixing surface lower than the height of the protrusion that is formed on the other side of the protrusion, and a locking groove formed through the protrusion in the width direction of the protrusion at a predetermined position on the vertical surface of the protrusion; a cutting blade having the same shape as the seating groove of the blade holder, having locking protrusions on both sides integrally formed on the lower side, and supporting surfaces formed at both ends; and a fixed block that is fixed to the fixing surface of the blade holder so that the locking protrusion on one side of the blade body does not deviate upward, wherein a coupling groove is formed in the center of the seating groove of the blade holder such that a coupling protrusion at the center of the bottom of the blade body is connected, and a gripping protrusion formed on the bottom of the fixed block is inserted by forming a gripping groove on the fixing surface of the blade holder.
