Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.

As Figure 1-3, the two-sided of the utility model embodiment processes vertical shaft milling cutter, comprise the axis hole 1 extended vertically being positioned at center, and around the horizontally disposed ring body 2 of axis hole 1, this ring body 2 comprises laterally extending upper surface 21, lower surface 22 and side face 23, axis hole 1 runs through this upper surface 21 and lower surface 22, and the diameter of phi of axis hole 1 is 35mm.

The side face 23 of this ring body 2 is uniformly distributed circumferentially and is provided with multiple claw 3, claw 3 is connected with the side face 23 of ring body 2 and radially side extends, and there are two spaced the first side 33 and the second sides 34, described first side 33 and the second side 34 annularly body 2 radial direction extend and close to each other laterally, this first side 33 is all connected with side face 23 with the second side 34, this claw 3 also comprises the upper face 31 be connected with the upper surface 21 of ring body 2, the lower surface 32 be connected with the lower surface 22 of ring body 2, this upper face 31 and lower surface 32 laterally extending.Downward-extension is all gone up in this first side 33 and the second side 34, and gradually towards the second side 34 direction bending or bending on the first direction radially, side 33, this first, second side and top, lower surface limit the size of this claw 3 mutually.And have distance h between this upper face 31 and outboard end of lower surface 32, this distance h is 10mm.Distance between the upper surface 21 of this ring body 2 and the lower surface 22 i.e. thickness of this ring body 2 is H, H is 36mm.

This first side 33 is the face of a bending, namely two mutual planes are at an angle comprised, namely with the tangent extension Part I 331 of the side face 23 of ring body 2 be connected the Part II 332 that bending laterally extends with Part I 331, this Part II 332 relative to Part I 331 towards the second side 34 direction bending.The position that the position that second side 34 of each claw 3 is connected with ring body 2 and the first side 33 of adjacent claw 3 are connected with ring body 2 is same place, namely described second side 34 extends from the initiating terminal of the first side 33 of adjacent another claw 3 of the claw 3 corresponding to it, namely tilts with the first side 33 from the position that the first side 33 of another claw 3 is tangent with side face 23 and stretches out.Namely can be connected successively between multiple claw, can certainly be on the side face 23 of ring body 2, have interval between multiple claw 3.This second side 34 is also a plane.Angle β between Part I 331 and Part II 332 is 36 °.

Angle γ is provided with between this second side 34 and axial direction of this milling cutter, this angle is γ is 7 °, this second side 34 is sticked the certain thickness blade 4 matched with this second side 34, the material of this blade 4 can be different from the material of claw 3 and ring body 2, be such as harder steel etc., so not only reduce overall cost, and only can change the longer service life that blade 4 makes milling cutter.Preferably, this claw 3 is four, and the angle α between the Part I 331 of the second side 34 of this claw 3 and the first side 33 of adjacent claw 3 is 67 °.The length L of the blade 4 on the second side 34 is 52.63mm.The thickness d of this blade 4 is 2mm.In four claws 3, the Part I 331 of the first side 33 of two claws 3 relatively is separately parallel to each other, and the distance D between the Part I 331 of the first side 33 of these two claws 3 is separately 53.9mm.

Further, the upper face 31 of this claw 3 is downward-sloping laterally, and the lower surface 32 of claw 3 is inclined upwardly laterally.Further, upper face 31 is identical with lower surface 32 tilt angle theta with respect to the horizontal plane, and θ is 7 °.Therefore, the two ends up and down of the blade 4 on the second side 34 form symmetrical two blades that can carry out cutting up and down.

And those skilled in the art also can recognize, not necessarily two sides of this claw will as described in said structure, such as the first side also can be the arcwall face bending to same direction, this second side also not necessarily plane, also can be arcwall face, that is, also can be that the circumference of this each claw annularly body 2 bends to a direction and forms the second side of an indent and the first side of evagination, as long as this first side and the second side are drawn close laterally gradually, and bend on the side of indent in claw 3, namely the second side is provided with the blade 4 that above-below direction is arranged.

This is two-sided processes vertical shaft milling cutter, not only simple and compact for structure, and the blade reasonable machining that distributes is efficient, and can upper and lower surface is two-sided carries out Milling Process to workpiece, and the cost reducing cutter extends cutting-tool's used life.

Although more than describe in detail preferred embodiment of the present utility model, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
