Specific embodiment
This utility model is further illustrated below by the mode of embodiment, but therefore this utility model is not limited in
Among described scope of embodiments.
As shown in figure 1, the plain milling cutter of the present embodiment includes rotary knife base 3, the first blade 1 and the second blade 2, rotation
There is tool rest 3 bottom surface 31, the first blade 1 and the second blade 2 to be periodically installed on rotary knife base 3.As shown in Figures 2 and 3,
Radius of turn of the radius of turn of the point of a knife 11 of one blade 1 more than the point of a knife 21 of the second blade 2, the point of a knife 21 of the second blade 2 are arrived
The distance of bottom surface 31 is more than the distance of the point of a knife 11 of the first blade 1 to bottom surface 31.In the present embodiment, the first blade 1 is thick adding
Work blade, the second blade 2 are polish blades, after the first blade 1 is processed, then process a little surplus by the second blade 2, it is ensured that every
The part of the processing of the second blade 2 is all finished through the first blade 1.The point of a knife 21 of the second blade 2 is to bottom surface 31
Distance is more than the distance of the point of a knife 11 of the first blade 1 to bottom surface 31, and this means that the depth of the processing of the second blade 2 is more than first
The depth of the processing of blade 1, it is ensured that after the first blade 1 is processed, the second blade 2 reprocesses a little surplus, so reaches
Higher workpiece surface quality.
As preferred scheme, the rotation half of the radius of turn of the point of a knife 11 of the first blade 1 than the point of a knife 21 of the second blade 2
Footpath is big at least 0.2 millimeter, as optimal scheme, the point of a knife 21 of the radius of turn of the point of a knife 11 of the first blade 1 than the second blade 2
Radius of turn it is big 0.5 millimeter.Rotation half of the radius of turn of the point of a knife 11 of the first blade 1 more than the point of a knife 21 of the second blade 2
Footpath difference r have one to be most worth, this least radius difference r and process rotary cutter point-to-point speed, rotary cutter rotary speed and
The adjacent angular difference of the first blade and the second blade is relevant.Assume that the point-to-point speed of rotary cutter is per second for V millimeters, rotary cutter
Rotary speed be m revolution per seconds, the first adjacent blade and the second blade clearance are 1/n circumference, then least radius difference r is V/
(m*n)。
In the present embodiment, the point-to-point speed of rotary cutter is 1000 millimeters per second, and the rotary speed of rotary cutter is 500
Revolution per second, the first adjacent blade and the second blade clearance are quarter turn, then least radius difference r is 1000/ (500*4), is
0.5 millimeter, that is to say, that the radius of turn of the point of a knife 11 of the first blade 1 than the point of a knife 21 of the second blade 2 radius of turn at least
Want big 0.5 millimeter, just can guarantee that the part of the processing of the second blade 2 each time is all finished through the first blade 1.Work as radius
Difference for 0.5 millimeter when, after the first blade 1 is processed every time, the second blade 2 is followed up processing at once, with highest working (machining) efficiency.
As preferred scheme, the distance of the point of a knife 21 of the second blade 2 to bottom surface 31 than the first blade 1 point of a knife 11 on earth
The distance in face 31 is big 0.05 millimeter to 0.15 millimeter.Used as optimal scheme, the point of a knife 21 of the second blade 2 arrives the distance of bottom surface 31
It is bigger 0.1 millimeter than the distance of point of a knife 11 to the bottom surface 31 of the first blade 1.This utility model is closed to different metal materials such as aluminum
Gold, magnesium alloy and copper alloy etc. are tested, and show the point of a knife 11 of 21 to the first blade 1 of point of a knife of the second blade 2 bottom of relative to
The fore-and-aft distance that face 31 projects has 0.1 millimeter of an optimum, when fore-and-aft distance is too little, does not have further polish
Effect, when fore-and-aft distance is too big, be easily caused metal surface deformation, cause worse surface quality.Table 1 is different finishings
The test that spare time amount is affected on aluminum alloy surface roughness, table 2 are affected on Mg alloy surface roughness for different allowances for finish
Test, the test that table 3 is affected on copper alloy surface roughness for different allowances for finish.
The test that 1 different allowances for finish of table are affected on aluminum alloy surface roughness
The test that 2 different allowances for finish of table are affected on Mg alloy surface roughness
The test that 3 different allowances for finish of table are affected on copper alloy surface roughness
In the plain milling cutter of the present embodiment, the number of the first blade 1 and the second blade 2 is respectively 1 to 4.As one
The number for planting preferred version, the first blade 1 and the second blade 2 is two.In process, surface matter of the chip to workpiece
Amount also has large effect, in order that chip removal is smooth, the outside of the first blade 1 and the second blade 2 has relative to bottom surface 31
The inclination alpha of place plane, as shown in Figures 4 and 5.Inclination angle is too little, then do not have the effect of chip removal, affects surface quality, inclines
Angle is too big, then point of a knife is too little with surface of the work contact surface, equally affects surface quality.In the present embodiment, inclination angle is selected to be 70 degree
To 80 degree, as a kind of optimal scheme, inclination angle is 75 degree, and the inclination angle in table 1 to table 3 is 75 degree of optimum.Table 4 shows
Impact of the different angle to aluminum alloy surface quality.In table 4, fore-and-aft distance difference is 0.1 millimeter of optimum, i.e. the second blade 2
Point of a knife 21 to bottom surface 31 distance than the first blade 1 point of a knife 11 to bottom surface 31 distance it is big 0.1 millimeter.Lateral separation difference
It is bigger than the radius of turn of the point of a knife 21 of the second blade 2 0.5 millimeter for optimum, the i.e. radius of turn of the point of a knife 11 of the first blade 1.
Impact of 4 different angle of table to aluminum alloy surface quality
As shown in figure 4, the point of a knife 11 of the first blade 1 is hard alloy, blade and point of a knife are integrally formed, as roughing knife
Piece.As shown in figure 5, the point of a knife 21 of the second blade 2 is diamond, as polish.Second blade is by the first blade scrapped
The nose part of the first blade is cut a unfilled corner by the transformation of the way, then welds upper diamond point of a knife, can serve as diamond essence
Processing blades, have so reused the roughing blade scrapped, have saved substantial amounts of material.
In the present embodiment, the first blade 1 and the second blade 2 are fixed by screws on rotary knife base 3.Certainly also not
It is limited to the fixed form with screw, it would however also be possible to employ the fixed form such as draw-in groove, riveting, interference fit.
The plain milling cutter of the present embodiment can carry out roughing and polish simultaneously, and working (machining) efficiency is doubled, while protecting
Hold preferable surface quality.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art
On the premise of without departing substantially from principle of the present utility model and essence, various changes or modifications can be made to these embodiments,
But these changes and modification each fall within protection domain of the present utility model.
