In view of this, the utility model provides a coarse and fine integrated four-edged round nose knife.
In order to achieve the above purpose, the utility model adopts the following technical scheme: coarse and fine integrated four-edge round nose cutter, comprising: the cutter comprises a cutter bar and a cutter head arranged at the front end of the cutter bar; the cutter head is provided with four peripheral edges along the direction of a longitudinal axis, the four peripheral edges are spirally arranged on the cutter head, and an interval space is formed among the four peripheral edges; the cutter head is provided with a bottom blade at one end far away from the cutter bar, the bottom blade is positioned at the top of the peripheral blade, the bottom blade is distributed in a butterfly-shaped angle, and chip grooves are formed between the bottom blades.
In a preferred technical scheme, the peripheral edge is provided with a first edge surface, and the bottom edge is provided with a second edge surface.
In a preferred embodiment, the first blade surface is spirally arranged in the direction of the peripheral edge.
In a preferred embodiment, the second blade surface is inclined to the adjacent bottom blade.
In a preferred technical scheme, the first edge surface is connected with the second edge surface.
In a preferred technical scheme, the chip grooves are communicated with the spacing space.
In a preferred technical scheme, the chip grooves are formed between adjacent bottom edges, and the open ends of the chip grooves are positioned at the joint of the four bottom edges.
In a preferable technical scheme, the side wall of the chip groove is concavely arranged in an outward arc shape.
Known through foretell technical scheme, compare with prior art, the utility model discloses following beneficial effect has: the utility model discloses a round nose sword is provided with four all swords and four end sword, and end sword butterfly shape angle sets up, has reinforceed the end sword, has effectively strengthened the sales volume of cutting to the chip groove of the strenghthened type that forms between the end sword can effectively strengthen the chip removal effect.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The rough and fine integrated four-edged round nose knife, as shown in fig. 1, includes: the cutter arbor 10 and set up the tool bit 20 in the cutter arbor 10 front end, cutter arbor 10 and the axial direction of tool bit 20 are connected, and cutter arbor 10 and tool bit 20 all just make with high rigidity metal material.
The cutter head 20 is provided with four peripheral blades 21 along the axial direction, and the peripheral blades 21 are provided. The four peripheral blades 21 are spirally distributed, but space is formed among the four peripheral blades 21, so that the four peripheral blades 21 are not spirally connected; the side of the peripheral edge 21 facing outwards is formed with a first edge face 211.
The end of the cutting head 20 away from the cutter bar 10 is formed with bottom edges 22, the number of the bottom edges 22 is four, the bottom edges 22 and the peripheral edge 21 are connected in a non-coplanar manner, that is, the bottom edges 22 are correspondingly arranged at the top of the peripheral edge 21, and the bottom edges 22 are formed with second edge surfaces 221.
In use, a cutting action is performed by the first and second blade surfaces 211, 221.
The first edge surface 211 is spirally formed along the forming direction of the peripheral edge 21, the second edge surface 221 is spirally inclined, each bottom edge 22 is formed with a second edge surface 221, and the second edge surface 221 is inclined toward the front bottom edge 22.
The four bottom edges 22 are arranged in a butterfly shape, and the interval between the adjacent peripheral edges 21 is gradually increased from inside to outside, i.e. the peripheral edges are gradually decreased from the central position of the cutter head 20 in the radial direction.
The top of the tool bit 20 is provided with a chip groove 23, the beginning of the chip groove 23 is located at the intersection of the four bottom edges 22, and the end is connected to the space of the peripheral edge 21, so that effective chip removal can be realized.
And the side wall of the chip removal groove 23 is concavely arranged in an outward arc shape, so that the chip removal effect can be effectively increased.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
