Abstract
The invention discloses a cut-off knife used for an automatic cutting machine, which comprises a flat-bar shaped cut-off knife body. The cut-off knife body comprises a knife handle, a blade and a knife back, wherein the front end of the blade is provided with an oblique cutting edge. The included angle of the cutting edge and the blade is between 38 and 40 degrees. The included angle of the cutting edge and the edge line of the black is 5.71 degrees. The cut-off knife body is made of W18Cr4V high speed steel. The cut-off knife used for the automatic cutting machine has the advantages of high cutting accuracy, long service life and high working efficiency.
Description
Technical field
The present invention relates to a kind of cutting tool, relate in particular to a kind of sanction bed cutter that is used for automatic cutting machines.
Background technology
The material that cut-off knife adopted that is used for automatic cutting machines in the existing market can not bear high temperature at high speed operation, fractures easily, can not adapt in high speed to pump.And because the design reasons of cutter self, the tough angle of the cutter that is adopted does not meet science, and will cut material easily in cutting work takes up.The degree of accuracy and precision for cutting are subjected to bigger influence.The problem that adopts this cutter to exist is: cutting low precision, production cost height and life-span are short, can not increase work efficiency.Thereby in modern processing, be badly in need of to want a kind of can cutting precision height, the sanction bed cutter of increasing work efficiency.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, and a kind of cutting precision height, long service life are provided, and the cut-off knife that is used for automatic cutting machines that can increase work efficiency.
The invention provides a kind of cut-off knife that is used for automatic cutting machines, comprise flat bar cut-off knife body, described cut-off knife body comprises handle of a knife portion, tough of cutter and knife back portion, is provided with the blade portion of inclination at the front end of the tough portion of described cutter.
The angle of described blade portion and the tough portion of described cutter is 38 °～40 °, is preferably 40 °.
The angle of described blade portion and described knife back portion is 5.5 °～5.8 °, is preferably 5.71 °.
The described cut-off knife body shaft of described blade portion front end edge to both sides folders in an acute angle, the angle of this acute angle is 20 °～25 °, is preferably 22 °.
Described blade portion front end edge perpendicular to described cut-off knife body shaft to both sides folders in an acute angle, the angle of this acute angle is 28 °～30 °, is preferably 30 °.
Described cut-off knife body is W
18Cr
4The V high-speed steel.
Owing to adopt technique scheme, the present invention has following beneficial effect: the present invention adopts the blade portion that is provided with the pre-determined tilt angle, make blade portion reasonable with cut material bonding station and angle, avoid in cutting work cut-off knife to cut material and take up, improved the degree of accuracy and the precision of product.Adopt W simultaneously
18Cr
4That the V high-speed steel has is high temperature resistant, frangibility not, is suitable for the advantage of high-speed working condition.
