Technical field
The utility model relates to a kind of wood cutter, especially relates to the anti-dise knife in a kind of oblique angle.
Background technology
What anti-dise knife adopted usually is the version of two swords, the installation quantity of cutting edge has determined that its working (machining) efficiency is lower, for the user must processing the reduction of product cost be disadvantageous, operating personnel use the cutter of this type, because the buoyancy of cutter when work is larger, its labour intensity is also larger.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of oblique angle anti-dise knife.
To achieve these goals, the utility model adopts following technical scheme:
The anti-dise knife in a kind of oblique angle, it has:
Shank, it is column;
Be located at the upper cutting portion of shank forward end, the blade that it has the main blade installation portion and is installed on the set blade installing port of main blade installation portion;
Be located at the bearing of cutting portion front end;
Be located at the lower cutting portion of bearing front end, the blade that it has auxiliary blade installation portion and is installed on the set blade installing port of auxiliary blade installation portion is characterized in that, described main blade installation portion has:
Three large blade installing ports of annular array are positioned at three large blade installing ports and are respectively equipped with the large blade that is in tilted layout;
Three small blade installing ports of annular array are positioned at three small blade installing ports and are respectively equipped with the small blade that is in tilted layout;
Described large and small blade installing port interval is arranged.
Further, the maximum depth value of described large blade installing port is greater than the maximum depth value of small blade installing port.
Further, described large and small blade adopts yg-type carbide to make.
Further, described large and small blade adopts welding manner to be installed on installing port.
Further, described large blade is divided near the first half section at main blade installation portion center with away from second half section at main blade installation portion center, and the cutting edge of the cutting edge of described second half section and first half section is not on the same straight line.
The beneficial effects of the utility model are:
A, increased the quantity of blade, the cutting output of each tooth has reduced under equal rotating speed, has improved the surface roughness of machined surface;
B, improved efficient, the speed of feeding can double.
Description of drawings
Fig. 1 is the side view of the anti-dise knife in oblique angle.
Fig. 2 is the upper cutting tip structural representation of the anti-dise knife in oblique angle.
Fig. 3 is the lower cutting part-structure schematic diagram of the anti-dise knife in oblique angle.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1～3, the anti-dise knife in a kind of oblique angle, it has: shank 1, it is column and surface roughness Ra is not more than 0.8; Be located at the upper cutting portion 2 of shank forward end, the blade that it has taper main blade installation portion and is installed on the set blade installing port of main blade installation portion; Be located at the bearing 3 of cutting portion front end; The lower cutting portion 4(that is located at the bearing front end installs with nut), the blade 410,411,412 that it has auxiliary blade installation portion 41 and is installed on the set blade installing port of auxiliary blade installation portion, described main blade installation portion has: three large blade installing ports 21,22,23 of annular array are positioned at three large blade installing ports and are respectively equipped with the large blade 210,220,230 that is in tilted layout; The three small blade installing ports 24,25,26 of annular array are positioned at three small blade installing ports and are respectively equipped with the small blade 240,250,260 that is in tilted layout; Described large and small blade installing port interval is arranged, large small blade installing port U-shaped in general shape.
Upper cutting portion is as the carrier of blade, and it is up big and down small revolving body, and namely Zhou Jing is diminished towards the lower end gradually by its upper end.
The cutting edge of large and small blade is towards all being counter clockwise directions, and the roughness Ra of blade face is not more than 3.2.
The maximum depth value of described large blade installing port is greater than the maximum depth value of small blade installing port, herein clean refers to deeply be the opening of blade installing port to installing port bottom distance or the length of (near main blade installation portion central side), the A/F of large blade installing port is greater than the A/F of small blade installing port.
Described large and small blade adopts yg-type carbide to make, and the length of two kinds of blades is inconsistent, large blade is responsible for the moulding of main shape, small blade helps large blade chipping allowance the best part, and the angle of inclination of small blade is opposite with large blade, take small blade 240 as example, it is tilted to the left 5 °, large 210 on blade is to be tilted to the right 8 ° (in like manner, large small blade all arranges by this kind mode), so structure can reduce the buoyancy (manually push away mill) of cutter when work.
Described large and small blade adopts welding manner to be installed on installing port.
Referring to Fig. 2, described large blade is divided near the first half section at main blade installation portion center with away from second half section at main blade installation portion center, the cutting edge of the cutting edge of described second half section and first half section is not on the same straight line, and the second half section, the oblique angle β with respect to the first half section was roughly 10 °.
This product adopts the 3+3 structure, improves the quantity of cutting edge (blade) in limited space, improves stock-removing efficiency, also reduces simultaneously labour intensity.
The processing mode of this product is: body passes through the turning moulding with No. 45 steel, then carry out milling at milling machine, alloy blade adopts the YG class, by high-frequency induction heating body and alloy blade, be welded on the body with the copper solder alloy blade, tool grinder is worn into the shape of various requirement after cleaning and the surface treatment.
