In description of the invention, unless otherwise restricted clearly, the words such as setting, installation, connection be shall be understood in a broad sense, institute
Above-mentioned word in the present invention specific can rationally be determined with the particular content of combination technology scheme by belonging to technical field technical staff
Meaning.
As shown in Figure 1, a kind of milling cutter, including knife handle 1, the milling portion 2 with 1 one of knife handle, the circumferential direction in milling portion 2 is set
Several side edges 3 extended spirally are equipped with, meanwhile, the end in milling portion 2 is additionally provided with shear blade 5, and shear blade 5 is connect with side edge 3, from
And milling cutter can be processed along the axis direction and radial direction of cutter.
As shown in Figure 1, the diameter of cutter is 14 millimeters, the length of cutter is 80 millimeters.Wherein, the length in milling portion 2 is
40 millimeters, meanwhile, milling portion 2 has certain taper, so that, milling portion 2 is relatively large in diameter close to one end of knife handle 1, milling portion 2
One end diameter far from knife handle 1 is smaller.
As shown in Fig. 2, there are six the side edge 3 settings, thus, the chipping allowance of workpiece is decomposed, enables cutter
To curved surface Continuous maching, the continually changing situation of chipping allowance is overcome.
The clast discharge generated will be processed for convenience, and adjacent side edge 3 cooperatively forms helical flute 4, it is preferred that spiral
The helical angle of chip space 4 is 30 °.
In order to solve processing curve workpiece problem encountered, the present embodiment special envoy side edge 3 is provided with 31 behind circular arc, circle
31 form 12 to 13 ° of relief angles behind arc, and 31 width is 0.8 to 0.9 millimeter behind circular arc.
Behind circular arc 31 formed relief angle be behind circular arc 31 starting point line and circular arc behind 31 starting point and milling
The angle that the line of centres in portion 2 is in, due to behind circular arc 31 width very little, 31 curvature meets milling portion 2 behind circular arc
Outer diameter requirement.
After improvement, on the one hand, the present embodiment by make side edge 3 have circular arc behind 31, thus, increase the thickness of side edge 3
Degree, improves the intensity of side edge 3, improves the anti-of cutting edge roundness and collapse performance, extend the service life of cutter.
On the other hand, simultaneously as 31 thickness for increasing side edge 3, the anterior angle of side edge 3 can suitably increase behind circular arc
Greatly, so that cutting edge is more sharp, cutting that can be brisk.
In another aspect, since side edge 3 has 31 behind circular arc, thus, 31 can suitably contact complexity behind circular arc
Processing curve squeezes machined curved surface, in turn, obtains good suface processing quality.
In order to reduce the abrasion of side edge 3, in some embodiments, 31 are connected with first flank 32 behind the circular arc, the
32 form 30 ° of relief angles behind one, and 31 overall width is 2 millimeters behind first flank 32 and circular arc.
In some embodiments, can with the side edge 3 at a distance from 2 center of milling portion be 0.3 to 0.4 millimeter, this away from
From for gap, not making the cutting edge of side edge 3 be more than the center in milling portion 2, measurement method is as shown in Figure 2.
The deviation at 2 center of side edge 3 and milling portion avoids processing from beating so that workpiece surplus smoothly enters before side edge 3
It is sliding to cause side edge 3 to be pressurized and towards 2 center curvature of milling portion.
Meanwhile in some embodiments, the side edge 3 can also be made to be provided with 7 ° of anterior angles, thus, facilitate by cutting swarf by
Sequential like becomes clastic, improves processing quality.
In order to improve the working ability of cutter ends, after shear blade 5 can be made to have planar back front, planar back front to form 7 ± 1 °
Angle, the width of planar back front are 0.7 to 1 millimeter.
Planar back front refers to for plane behind this, is not curved surface.
Shear blade 5 is provided with planar back front, it is possible to reduce shear blade 5 cuts the resistance of workpiece, and shear blade 5 is rapidly cut
It cuts.
Similarly, 6 ° of axial rake of the shear blade 5 can be made, while guaranteeing that cutting is sharp, so that the intensity of shear blade 5
It will not reduce.
More optimize, in order to reduce the friction of shear blade 5 Yu machined surface, reduces tool wear, can make described straight
It is connected with second flank below, second flank forms 14 ° of relief angles.
Since workpiece face to be processed is curved surface, inevitably need to be added using the junction of shear blade 5 and side edge 3
Work, for avoid the junction of side edge 3 and shear blade 5 occur collapsing it is scarce, as shown in figure 3, the shear blade 5 can be made to be provided with connection side edge
3 knuckle 7 and reinforcement sword 8, reinforces sword 8 and connect with side edge 3, and the width for reinforcing sword 8 is 0.17 to 0.2 millimeter.
Meanwhile the clast discharge in order to process shear blade 5, meanwhile, avoid the abutting of 2 center of milling portion and workpiece can be with
So that the end center in the milling portion 2 is provided with counterbore 6, forms empty avoiding.
Meanwhile the counterbore 6 can be made including cone hole part, the blind hole portion for being set to cone hole part small end, be set to cone hole part
The circular hole portion of big end.
To which counterbore 6 is also used as the location hole of manufacture milling cutter, facilitates the manufacture of milling cutter.
Above embodiments are not limited to the technical solution of the embodiment itself, can be incorporated between embodiment new
Embodiment.The above embodiments are merely illustrative of the technical solutions of the present invention and is not intended to limit it, all without departing from the present invention
Any modification of spirit and scope or equivalent replacement, shall fall within the scope of the technical solution of the present invention.
