Abstract
The utility model relates to a vertically-mounted heavy-cutting double-edge blade, which comprises a rectangular blade body, wherein the rectangular blade body is provided with a central hole, cutting edges are formed on two opposite sides of the rectangular blade body, each cutting edge is a boss which is parallel to the side surface of the rectangular blade body and is smaller than the side surface of the rectangular blade, a concave arc chip breaker groove is formed from the side surface of the rectangular blade body to the lower part of the boss in a downward inclining mode, the included angle between the inclined angle of the side surface of the rectangular blade body and the horizontal plane is 16 degrees, and the inner radius of the concave arc chip breaker groove is R1.5. The vertically-mounted heavy-cutting double-edge blade has the advantages of light and fast cutting, good chip breaking, low noise and higher processing precision.
Description
Technical Field
The utility model relates to the technical field of milling cutter blades, in particular to a vertical heavy-cutting double-edged blade.
Background
In the heavy cutting process field, in order to reduce process time, when the milling cutter blade depth of cut is great commonly used, the load that the cutter bore is big, it is big to cause the blade consumption, the blade atress is uneven, cause the blade when with the work piece contact, the cutting is not light fast, produce great vibrations, and then produce great noise, influence the processing effect, the iron fillings of cutting are rectangular form, need artifical supplementary, difficult chip removal, the blade often can appear vibrating greatly in the in-service use process, the load is big, the big problem of noise.
Disclosure of Invention
Aiming at the defects of the existing vertical heavy-cutting double-edged blade, the utility model provides the vertical heavy-cutting double-edged blade which has the advantages of light and fast cutting, good chip breaking, low noise and higher processing precision.
The technical scheme of the utility model is as follows: immediately, adorn heavy cutting twolip blade, including cuboid blade body, cuboid blade body has the centre bore, and the relative both sides of rectangle blade body form the cutting edge, the cutting edge is for being less than the boss of cuboid blade side with the parallel and width in side of cuboid blade body, forms concave arc chip breaker from the side downward sloping of cuboid blade body to the boss lower part, the inclination of the side of cuboid blade body is 16 with the contained angle of horizontal plane, the inner radius of concave arc chip breaker is R1.5.
Preferably, the cross section of the concave arc chip breaker is J-shaped, so that the cutting is easier, and the vibration is reduced.
Preferably, the cuboid blade body is the vertical corner cut cuboid, avoids the side sharpness fish tail personnel when overhauing.
The vertically-installed heavy-cutting double-edge cutter has the advantages that when large cutting depth load is large, the design of the concave arc chip breaker groove is high in cutting edge safety and strong in impact resistance, high metal cutting rate and low cutting force can be obtained under large-depth cutting and large-feed processing parameters, the chip breaker groove greatly reduces friction between chips and a front cutter face of a blade, the possibility of bonding between the chips and the front cutter face is reduced, cutting is light and rapid, and chip removal is smoother, so that higher workpiece surface quality and longer service life of the blade can be obtained, the cutting edge of the blade is sharper due to the large front angle and the back angle of the blade, cutting is lighter and quicker under the condition that effective chip breaking of the blade is guaranteed, noise during processing is reduced, the blades on two sides of a cuboid blade body are arranged, the blades can be utilized for 2 times, cost is saved, and waste is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1-4, the vertically-mounted heavy-cutting double-edged blade comprises a rectangular blade body 1, wherein the rectangular blade body 1 is provided with a central hole 2, two opposite sides of the rectangular blade body 1 form cutting edges 3, each cutting edge 3 is a boss parallel to the side surface of the rectangular blade body 1 and has a width smaller than that of the side surface of the rectangular blade body 1, a concave arc chip breaker groove 4 is formed from the side surface of the rectangular blade body 1 to the lower part of the boss in a downward inclined manner, the inclined angle of the side surface of the rectangular blade body 1 and the included angle of the horizontal plane are 16 degrees, and the inner radius of the concave arc chip breaker groove 4 is R1.5.
Furthermore, the section of the concave arc chip breaker groove 4 is J-shaped, so that the cutting is easier, the chip removal is smooth, and the vibration is reduced.
Further, cuboid blade body 1 is vertical corner cut cuboid, avoids the side sharpness fish tail personnel when overhauing.
In specific implementation, as shown in fig. 5, a cuboid blade body 1 of the vertically-installed heavy-cutting double-edged blade of the utility model is fixed around a cutter head 5 of a cutting machine at intervals by a bolt through a central hole 2, cutting is started, friction between chips and a front blade surface of the blade is greatly reduced by the convex design of a cutting edge 3 on the cuboid blade body 1 and the concave design of a concave arc chip breaker groove 4, the possibility of bonding between the chips and the front blade surface is reduced, cutting is lighter and smoother, so that higher workpiece surface quality and blade service life can be obtained, an included angle between an inclination angle of the side surface of the cuboid blade body 1 and a horizontal plane is 16 degrees, the cutting edge is thicker, the cross-sectional shape of the concave arc chip breaker groove 4 is J-shaped, and compared with the traditional V-shaped, the cutting edge is more wear-resistant and impact-resistant, easier to cutting, vibration is reduced, noise is reduced, machining precision is higher, and the cutting edges on both sides are arranged, the direction of the blade can be changed, the blade can be utilized for 2 times, and the cost is saved.
