Abstract
The utility model relates to the field of milling cutters which basically consists of curves, in particular to a surface milling cutter with an arc-shaped cutting edge. The surface milling cutter with the arc-shaped cutting edge comprises a cutter rest (1) and a milling cutter blade (2), wherein the milling cutter blade (2) is fixed on the cutter rest (1); the surface milling cutter with the arc-shaped cutting edge is characterized in that the shape of the milling cutter blade (2) is composed of an arc edge (21), a straight edge (22) and an inclined edge (23) which are connected in sequence end to end, wherein the central angle of the arc edge (21) is not greater than 90 degrees; the included angle between the straight edge (22) and the inclined edge (23) is between 40degrees and 60 degrees; both the arc edge (21) and the straight edge (22) serve as cutting edges; and the arc edge (21) and the straight edge (22) are respectively flush with the outer edge of the cutter rest (1). The surface milling cutter with the arc-shaped cutting edge is simple in structure, convenient to use, high in machining quality, and wide in application range.
Description
Technical field
The utility model relates to the milling cutter field being substantially made up of curve, is specially a kind of face milling cutters with arc milling sword.
Background technology
Common equipment when milling machine is machining, because milling cutter is multitooth tool, has advantages of that working (machining) efficiency is high, machining accuracy is high.But current milling cutter adopts straight sword smoothing in the time of machining, be difficult to adapt to the processing that effects on surface fineness is had relatively high expectations, this has just limited the application of milling machine.
Utility model content
In order to overcome the defect of prior art, a kind of simple in structure, easy to use, cutting machines that crudy is high is provided, the utility model discloses a kind of face milling cutters with arc milling sword.
The utility model reaches goal of the invention by following technical solution:
A kind of face milling cutters with arc milling sword, comprise knife rest and cutting plate for milling cutters, cutting plate for milling cutters is fixed on knife rest, it is characterized in that: the shape of cutting plate for milling cutters is by arc-shaped edges, straight flange and hypotenuse and connects and composes from beginning to end successively, wherein, the central angle of arc-shaped edges is not more than 90 °, and the angle forming between straight flange and hypotenuse is at 40 °～60 °, arc-shaped edges and straight flange are all as cutting edge, and arc-shaped edges and straight flange flush with the outer rim of knife rest respectively.
The described face milling cutters with arc milling sword, it is characterized in that: between arc-shaped edges and straight flange, connect by arc transition or by a broken line, if the line segment being connected with arc-shaped edges in broken line is the first line segment, if the line segment being connected with straight flange in broken line is the second line segment, the angle of cut between the first line segment and straight flange is 120 °～150 °, and the angle of cut between the second line segment and straight flange is 15 °～45 °.
The described face milling cutters with arc milling sword, is characterized in that: the central angle of arc-shaped edges is not more than 20 °.
When the utility model uses, straight flange plays shear action, and arc-shaped edges plays smoothing effect, and the surface smoothness Rz of machined surface can reach 0.1 μ m～0.5 μ m, in the case of cutting apparatus not being done can realize high accuracy processing large change.
The beneficial effects of the utility model are: simple in structure, easy to use, crudy is high, applied widely.

Detailed description of the invention
Further illustrate the utility model by specific embodiment below.
Embodiment 1
Have face milling cutters for arc milling sword, comprise knife rest 1 and cutting plate for milling cutters 2, as shown in Figure 1 to 4, concrete structure is:
Cutting plate for milling cutters 2 is fixed on knife rest 1;
The shape of cutting plate for milling cutters 2 is by arc-shaped edges 21, straight flange 22 and hypotenuse 23 and connects and composes from beginning to end successively, wherein, the central angle of arc-shaped edges 21 is not more than 90 ° of the present embodiment and gets 20 °, the angle forming between straight flange 22 and hypotenuse 23 is at 40 °～60 °, the present embodiment is got 45 °, arc-shaped edges 21 and straight flange 22 are all as cutting edge, and arc-shaped edges 21 and straight flange 22 flush with the outer rim of knife rest 1 respectively.
In the present embodiment, between arc-shaped edges 21 and straight flange 22, connect by arc transition one broken line 24, if the line segment being connected with arc-shaped edges 21 in broken line 24 is the first line segment 241, if the line segment being connected with straight flange 22 in broken line 24 is the second line segment 242, the angle of cut between the first line segment 241 and straight flange 22 is that the α in Fig. 4 is 120 °～150 °, the present embodiment α gets 135 °, the angle of cut between the second line segment 242 and straight flange 22 is that the β in Fig. 4 is 15 °～45 °, the present embodiment β gets 15 °, and the angle of cut between the first line segment 241 and the second line segment 242 is 120 °.Between arc-shaped edges 21 and straight flange 22, also can pass through arc transition.
When the present embodiment uses, 22 shear actions of straight flange, arc-shaped edges 21 plays smoothing effect, and the surface smoothness Rz of machined surface can reach 0.1 μ m～0.5 μ m, in the case of cutting apparatus not being done can realize high accuracy processing large change.
