Title:
CUTTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/064590
Kind Code:
A1
Abstract:
The present invention not only eliminates bouncing of a rod material during cutting but also makes replacement of a stationary blade and a pressing member and cleaning work of the stationary blade and the surrounding of the pressing member easy. A pressing member-side inclined surface (65) of a pressing member (6) is pressed downward by a clamp block-side inclined surface (542) of a clamp block (54), thereby press-clamping a rod material (13) with a pressing section (621) of a pressing bushing (62). The clamp block-side inclined surface (542) and pressing member-side inclined surface (65) are formed so as to have an inclination angle (θ) of six degrees. Because this inclination angle (θ) is set to an angle at which a component force of the pressing force becomes smaller than the maximum frictional force generated between the pressing member-side inclined surface (65) and clamp block-side inclined surface (542), the clamp block (54) and a piston rod (551) do not move back leftward (in the unclamping direction) even when a large reaction force has acted upon the pressing member (6) during the cutting of the rod material (13). Bouncing of the rod material (13) during the cutting is eliminated, thereby enabling stable billets with improved cutting precision to be manufactured.
