Utilizing the included angle between the front cutter face and the welded big face, corresponded front angle is naturally formed after the blade is welded on the cutter body, thereby the cutting edge of a cutter is sharper, simultaneously, the size and intensity of the welded large face of the cutting body are effectively guaranteed, the utility model is beneficial for guaranteeing the process quality, and can be extensively applied in a current integral welded style cutter.
Description
Technical field
The utility model relates to a kind of cutter, especially a kind of milling cutter and blade thereof of being used for.
Background technology
At present, in automobile manufacture industry, vehicle window frame adopts the mode of milling pin to process the vehicle window profile usually.Processing automobile process tool that window frame uses is generally integral solder formula milling cutter, promptly processes the side solder side and the big face of welding of blade on cutter hub, then blade is weldingly fixed on the cutter hub.The side solder side of this milling cutter body is vertical mutually with the big face of welding, and the side solder side between cutter hub and the blade is corresponding with the big face of welding.The rake face of big face of the welding of blade and blade is the plane that is parallel to each other, and therefore, blade welded and installed back on cutter hub forms 0 ° of anterior angle usually and maybe can only obtain less anterior angle, as shown in Figure 1 and Figure 2; If obtain bigger anterior angle, under the situation of same weld face and weld strength, will can't process the big solder side with the big face coupling of welding of blade on the cutter hub, as shown in Figure 3, thereby make and can't obtain bigger anterior angle, have influence on the sharpness of milling cutter.Anterior angle is more little, and blade is big more to the extruding degree of machined surface, and machined surface stress deformation degree is also big more, thereby influences crudy.
The utility model content
Technical problem to be solved in the utility model provides a kind of big anterior angle, milling cutter and blade thereof that cutting edge is sharp of obtaining.
The technical scheme that its technical problem that solves the utility model adopts is: this milling cutter comprises cutter hub and the blade that is welded on the cutter hub, the welding side of cutter hub is corresponding with the big face of welding with the welding side of blade respectively with the big face of welding, the cutting edge of blade extends axially along cutter hub, is provided with angle between the rake face of blade and the big face of welding.Utilize the rake face of blade and weld the angle that is provided with between the big face, after being welded to blade on the cutter hub, forming pairing anterior angle naturally, thereby make the cutting edge of its cutter sharper.
As to further improvement in the technical proposal, for satisfying the processing request of vehicle window frame profile in automobile manufacture industry, cutter hub upper edge axially spaced-apart certain distance is arranged with two blades, forms the dedicated tool of high efficiency processing vehicle window profile.
As to further improvement in the technical proposal, the cutting edge of above-mentioned two blades staggers 180 ° in a circumferential direction mutually.
Blade is provided with angle between its rake face and the big face of welding.
As to further improvement in the technical proposal, above-mentioned angle is 15 °.
The beneficial effects of the utility model are: since adopted with the rake face of blade with weld the technical scheme that is provided with angle between the big face, the big I of its angle designs as required, thereby after being welded on blade on the cutter hub, make it directly produce needed anterior angle, can guarantee effectively also that simultaneously cutter hub welds the size and the intensity of big face, make the cutting edge of its cutter sharper, help guaranteeing crudy, can be widely used on the existing integral solder formula cutter.
Description of drawings

Fig. 2 is that existing integral solder formula milling cutter is the blade position layout drawing when obtaining less anterior angle.
Fig. 3 is existing integral solder formula milling cutter when obtaining big anterior angle, and the layout drawing of the necessary adjustment of blade position can't not realized because of there being the big face of welding this moment.
Fig. 4 is milling cutter of the present utility model location arrangements figure during knife face behind the relief grinding not after welding, can form big anterior angle.
Fig. 5 is the location arrangements figure of milling cutter of the present utility model behind knife face behind welding and the process relief grinding, can form big anterior angle.
Fig. 6 is the outline drawing of a specific embodiment of milling cutter of the present utility model.
Be labeled as among the figure: cutter hub 1, blade 2, rake face 3, the big face 4 of welding, welding side 5, cutting edge 6, welding side 7, the big face 8 of welding, angle α.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 4, shown in Figure 5, milling cutter of the present utility model, comprise cutter hub 1 and the blade 2 that is welded on the cutter hub 1, the welding side 5 of cutter hub 1 and the big face 4 of welding are corresponding with the big face of the welding side 7 of blade 2 and welding 8 respectively, the cutting edge 6 of blade 2 extends axially along cutter hub 1, is provided with angle α between the rake face 3 of blade 2 and the big face 7 of welding.Utilize the rake face 3 of blade and weld between the big face 7 to be provided with angle α, after being welded to blade on the cutter hub, forming pairing anterior angle naturally, thereby make the cutting edge of its cutter sharper.The rake face 3 of blade and the angle α of welding between the big face 7 usually can be between 5～20 °, thereby obtain 5～20 ° anterior angle easily.
The design of blade 2 can be selected different angle α according to actual needs for use, after being welded on the cutter hub 1, just can form the anterior angle that needs like this, forms relief angle by knife face behind the steel body relief grinding, obtains comparatively sharp milling cutter, as shown in Figure 4.If need obtain bigger anterior angle, also can obtain the milling cutter of big anterior angle, and also can guarantee that the solder side area of milling cutter cutter 2 is constant substantially this moment by adjusting relative position, weld strength also can guarantee.
Generally, the welding side 5 of its cutter hub 1 is vertical mutually with the big face of welding 4, can reduce manufacturing cost and difficulty of processing like this.
Embodiment:
In auto manufacturing, for enhancing productivity, the processing of vehicle window frame profile can adopt special-purpose integral solder formula milling cutter to process.The middle part of window frame is a positioning strip, need be that benchmark is processed the window frame of positioning strip both sides with the surface of the positioning strip at middle part, milling between the surface of the positioning strip in the middle part of machined surface and the window frame after the pin processing has certain status requirement, need be guaranteed man-hour adding.
For satisfying above-mentioned processing needs, milling cutter of the present utility model, welding blade 2 on cutter hub 1, and the big face of the welding side 5 of cutter hub 1 and welding 4 is vertical mutually, and the welding side 5 of cutter hub 1 and the big face 4 of welding are respectively with the welding side 7 of blade 2 and to weld big face 8 corresponding.Cutter hub 1 upper edge axially spaced-apart certain distance is arranged with two blades 2, the cutting edge of two blades 2 staggers 180 ° in a circumferential direction mutually, cutting edge 6 the extending axially of blade 2 along cutter hub 1, be provided with 15 ° of angle α between the rake face 3 of blade 2 and the big face 7 of welding, form side set cutter with two cutting edges.Form relief angle by knife face behind the steel body relief grinding, obtain comparatively sharp milling cutter.
