Abstract
The utility model relates to the technical field of milling tools, in particular to a milling tool blade for processing a car cylinder upper end face, which comprises a cutter body and a tool bit welded on the cutter body. An included angle is disposed at the connecting portion of the cutter body and the tool bit, wherein an arc with the radius of 0.8mm is additionally arranged at the connecting portion of a main cutting edge and an auxiliary cutting edge of the cutter body. The tool bit and the blade of the milling tool blade for processing the car cylinder upper end face are closely attached, and the milling tool blade for processing the car cylinder upper end face is good in fixing, resistant to abrasion and long in service life.
Description
Technical field
The utility model relates to the technical field of milling cutter, particularly relates to a kind of processing automobile cylinder body upper surface cutter blade.
Background technology
Metal part processing be unable to do without cutter, particularly along with the improvement of development of science and technology and material, to process tool require increasingly high.The cutter blade that in the process of motor cylinder block upper surface, uses is welded by cutter head and cutter hub, and the design of the vertical angle place chamfering of cutter hub and cutter head weld influences the fixed mass of cutter head, makes that cutter head comes off easily in the cutter use, and is insecure; In addition because the front cutting edge of the problem, particularly cutter of cutter structure is straight sword, and main cutting edge is the right angle with the front cutting edge junction, makes that the workpiece surface quality of processing is poor, cutter flank wear piece, and the life-span lacks.
Summary of the invention
For existing problem in the above-mentioned prior art of better solution, the utility model provides cutter hub and cutter head firm welding, and the cutter back is wear-resisting, a kind of processing automobile cylinder body upper surface cutter blade of long service life.
In order to realize the foregoing invention purpose; The technical scheme of the utility model is: a kind of processing automobile cylinder body upper surface cutter blade; Comprise cutter hub and be welded on the cutter head on the cutter hub; There is an angle cutter hub and cutter head junction, and wherein, the main cutting edge of said cutter hub and front cutting edge junction have increased a circular arc that radius is 0.8mm.
The processing automobile cylinder body upper surface cutter blade of the utility model, wherein, said front cutting edge is circular-arc, the radius of circular arc is 300mm.
The processing automobile cylinder body upper surface cutter blade of the utility model, wherein, said angle is for being a wide 0.3mm, the oblique angle of dark 0.05mm.
The processing automobile cylinder body upper surface cutter blade of the utility model, wherein, said cutter head material is a polycrystalline cubic boron nitride, the cutter hub material is a carbide alloy.
Beneficial effect:
1, the applying of the utility model processing automobile cylinder body upper surface cutter blade cutter head and blade is tight, and stationarity is good.The utility model processing automobile cylinder body upper surface cutter blade is provided with a wide 0.3mm at cutter hub welding cutter head place, and the oblique angle of dark 0.05mm makes cutter head and cutter hub be adjacent to welding, fixation, difficult drop-off during use.
2, the utility model processing automobile cylinder body upper surface cutter blade is wear-resistant, long service life.The main cutting edge and the front cutting edge junction of the utility model processing automobile cylinder body upper surface cutter blade have increased a small circular arc; And it is circular-arc that front cutting edge is; Changed the way of contact of Tool in Cutting sword and workpiece; Become by the transition contact of putting line by original line contact, reduced the cutting resistance of cutter, improved the surface quality of working (machining) efficiency and workpiece.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the processing automobile cylinder body upper surface cutter blade in the utility model is done further detailed description.
In the drawings, cutter hub 1, cutter head 2, main cutting edge 3, front cutting edge 4, angle 5.
Referring to Fig. 1, Fig. 2, Fig. 3; A kind of processing automobile cylinder body upper surface cutter blade; Comprise carbide alloy cutter hub 1 and be welded on the polycrystalline cubic boron nitride milling head 2 on the cutter hub 1; Cutter hub 1 has an angle 5 with cutter head 2 junctions, and wherein, the main cutting edge 3 and front cutting edge 4 junctions of said cutter hub 1 have increased a circular arc that radius is 0.8mm.
Said front cutting edge 4 is circular-arc, and arc radius is 300mm.
Said angle 5 is a wide 0.3mm, the oblique angle of dark 0.05mm.
Claims (4)
1. processing automobile cylinder body upper surface cutter blade; Comprise cutter hub and be welded on the cutter head on the cutter hub; There is an angle cutter hub and cutter head junction, it is characterized in that: the main cutting edge of said cutter hub and front cutting edge junction have increased a circular arc that radius is 0.8mm.
