Abstract
The utility model discloses a spiral milling blade which comprises a blade body, wherein a screw hole is formed in the center of the blade body; a sleeking blade is arranged on an arc edge of the blade body; a spiral cutting edge is arranged on a linear edge; on two side faces where the arc edge is positioned, a hollowing position is arranged on one side face, and a positioning face and a hollowing position are arranged on the other side face; and hollowing positions are arranged on two side faces where the linear edge is positioned. According to the sleeking blade, the quality of the machined surface can be higher, the cutting force is resolved through the spiral cutting blade, and the cutting resistance is reduced, so that the cutting is quick. Moreover, according to the hollowing positions, the blade can generate air negative pressure during high-speed rotation, the air flow is accelerated, and a cooling effect is enhanced.
Description
Technical field
The utility model relates to machining tool, is specifically related to a kind of helical milling blade.
Background technology
Milling cutter, for Milling Process, have the rotary cutter of one or more cutters tooth.When work, each cutter tooth cuts the surplus of workpiece successively off and on.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece etc. on milling machine.
Size is accurate not again for the common problem of milling cutter, and its solution is generally: as being excessively cutting, the degree of depth and width while lowering cutting; As machine or fixing tool shortage accuracy, repair a machine and fixing tool; As machine or fixing tool shortage rigidity, change machine, fixing tool or cutting and set; As sword number very little, use multiple-cutting-edge end mill(ing) cutter.
And the long cutting edge cutter blade of tradition, has processing resistance large, weak heat-dissipating, the defect that cutter life is low.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide one can reduce processing resistance, and good screw-on cutter dispels the heat.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of helical milling blade is provided, and it comprises blade body, and the both sides of blade body are with the Central Symmetry of blade body, and the center of blade body is screw hole; Described blade body is provided with centrosymmetric two camber line ribs and two straight line ribs, and its mean camber line rib is provided with wiper edges, and straight line rib is provided with spiral cutting sword; Two sides at camber line rib place, one of them side is provided with forces room, and another side is provided with locating surface and forces room; Two sides at straight line rib place are provided with forces room.
Preferably, between wiper edges and spiral cutting sword, be connected with tool arc.
Preferably, between camber line rib and screw hole, be provided with type groove.
In sum, the utlity model has following advantage:
Wiper edges can allow surface to be machined quality higher, and spiral cutting sword decomposes cutting force, reduces cutting resistance and makes cutting more brisk; Longer cutting edge, has improved clearance.Force room can allow blade production air negative pressure in High Rotation Speed, accelerate Air Flow, strengthen cooling-down effect.Locating surface and screw hole are fixed on blade on knife bar by screw, and groove design not only allows blade attractive in appearance, and to allow iron cut be a contact in blade face as far as possible, and heat is cut and taken away by iron, increase blade service life.

Fig. 2 is side view of the present utility model;
Fig. 3 is top view of the present utility model.
Wherein, 1, wiper edges; 2, tool arc; 3, spiral cutting sword; 4, type groove; 5, locating surface; 6, force room; 7, screw hole; 8, force room; 9, camber line rib; 10, force room.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1 to Figure 3, the utility model provides a kind of helical milling blade, comprises blade body, and the both sides of blade body are with the Central Symmetry of blade body, and the center of blade body is screw hole 7.Blade body is provided with centrosymmetric two camber line ribs 9 and two straight line ribs, its mean camber line rib 9 is provided with wiper edges 1, between camber line rib 9 and screw hole 7, be provided with type groove 4. straight line ribs and be provided with spiral cutting sword 3, between wiper edges 1 and spiral cutting sword 3, be connected with tool arc 2.Two sides at camber line rib 9 places, one of them side is provided with forces room 8, another side are provided with locating surface 5 and force room 6.Two sides at straight line rib place are provided with forces room 10.
The end face of blade body is operate portions, has comprised wiper edges 1 and spiral cutting sword 3 on it.The both sides of blade body refer to the Central Symmetry of blade body, the center of circle that the Central Symmetry point of blade body is screw hole 7.Described Central Symmetry refers to, two camber line ribs 9 of blade body are centrosymmetric, and two straight line ribs are centrosymmetric; Its medium cell 4 is also centrosymmetric, and is provided with two groups of type grooves 4 on the termination of blade body.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction of the protection domain to this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
