Abstract
The utility model relates to the technical field of hardware knifes, in particular to an internal circular arc knife set, which comprises a knife handle and a knife bar arranged integrally, wherein the knife handle and the knife bar are concentric cylinders; the knife bar comprises a bottom blade, a first blade, a second blade and two straight grooves; the bottom blade is arranged at the front end of the internal circular arc knife set; the first blade and the second blade are concavely arranged on two sides of the knife bar; the straight groove is formed in one side of the second blade; both the first blade and the second blade are circular arc surfaces; the first blade and the second blade are mutually symmetrical along the axis of the knife bar. The internal circular arc knife set disclosed by the utility model is reasonable in structure, high in integral intensity and good in uniformity, the machining efficiency of elliptic cylinders can be effectively increased, the elliptic cylinders can be machined and formed for one time, the machining flow is simplified; the bar stock is directly formed.
Description
Technical field
The utility model relates to hardware and cutting-tools technical field, particularly a kind of interior circular arc cover cutter.
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.
In prior art, conventionally in the time of processing cylindroid shape, thereby need to repeatedly process and reach requirement, like this, both reduced production efficiency, its uniformity also has problem, simultaneously in order to ensure the intensity of milling cutter, often knife bar takies more processing space, causes the minimizing in chip removal space, easily causes tool wear and crumbles.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of interior circular arc cover cutter rational in infrastructure, easy to use is provided.
For achieving the above object, the utility model is by the following technical solutions:
Circular arc cover cutter in one described in the utility model, comprise the handle of a knife and the knife bar that are wholely set, described handle of a knife and knife bar are the cylindrical of same circle, described knife bar comprises the shear blade that is arranged at interior circular arc and overlaps cutter front end, the first blade, the second blade and the straight trough that depression is arranged at described knife bar both sides, described straight trough is arranged at described the second blade one side, described the first blade and the second blade are arc surface, and the first blade and the second blade symmetrical along the axis of described knife bar.
Further, described straight trough is cut sth. askew and is arranged on described knife bar.
Further, the number of described straight trough is two, is symmetricly set in the both sides of described the second blade along the axis of described knife bar.
Further, described handle of a knife end is provided with a location division.
Further, described the first blade, the second blade and straight trough are one-body molded.
The utility model beneficial effect is: the utility model is rational in infrastructure, and cutter bulk strength is better, can effectively improve cylindroid working (machining) efficiency, can time processing moulding for cylindroid, simplify work flow, and directly form bar, high conformity.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, circular arc cover cutter in one described in the utility model, comprise the handle of a knife 1 and the knife bar 2 that are wholely set, handle of a knife 1 and knife bar 2 are the cylindrical of same circle, knife bar 2 comprises the shear blade 21 that is arranged at interior circular arc and overlaps cutter front end, the first blade 22, the second blade 23 and the straight trough 24 that depression is arranged at knife bar 2 both sides, straight trough 24 is arranged at the second blade 23 1 sides, and the first blade 22 and the second blade 23 are arc surface, and the first blade 22 and the second blade 23 symmetrical along the axis of knife bar 2.
It should be noted that, straight trough 24 is cut sth. askew and is arranged on knife bar 2, and the number of straight trough 24 is two, is symmetricly set in the both sides of the second blade 23 along the axis of knife bar 2.Straight trough 24 has increased the chip removal space of interior circular arc cover cutter, and smear metal can be discharged smoothly, has avoided to a great extent the wearing and tearing of cutter and has crumbled.
Meanwhile, handle of a knife 1 end is provided with a location division 11, for the location of process.
The first blade 22, the second blade 23 and straight trough 24 are one-body molded, strengthen the bulk strength of cutter, process in cylindroid process at interior circular arc cover cutter, cylindroid energy one-shot forming processing, simplify work flow, directly form bar, when improving working (machining) efficiency, greatly improved cylindroid uniformity.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
