Description
Technical Field
The utility model relates to a cutter, in particular to a step counter bore forming cutter.
Background
As shown in fig. 1, when a workpiece 100 with a counter bore 101 is machined, the counter bore 101 is molded by a cutter, in the existing machining process, an arc surface, a chamfer angle and a straight wall of the counter bore 101 are respectively machined by three cutters, namely a circular nose cutter, a chamfer angle cutter and a flat bottom cutter, and when the machining is performed, three cutters are required to be replaced, on one hand, the cutter is required to be replaced in the machining process, the machining time is long, and on the other hand, the concentricity of the counter bore 101 is easy to deviate.
Disclosure of Invention
The utility model aims to provide a step counter bore forming cutter with high processing efficiency and high processing precision.
In order to achieve the above object, the technical solution of the present utility model is:
the utility model relates to a step counter bore forming cutter which comprises a cutter bar and a cutter head; the tool bit is arranged at the end part of the tool bar; the cutter head is sequentially provided with four stepped surfaces from inside to outside, and an arc-shaped cutter edge, an inclined plane cutter edge and a vertical plane cutter edge are respectively arranged between the four stepped surfaces from inside to outside, wherein the outer diameter of the arc-shaped cutter edge is larger than that of the inclined plane cutter edge, and the outer diameter of the inclined plane cutter edge is larger than that of the vertical plane cutter edge.
And a chip flute is arranged on one side of the arc-shaped knife edge, the inclined plane knife edge and the vertical plane knife edge.
The cutter head is provided with two opposite cutter edge seats at the outer end, four stepped surfaces are sequentially arranged on the outer walls of the two cutter edge seats, and an arc-shaped cutter edge, an inclined plane cutter edge and a vertical plane cutter edge are respectively arranged between the four stepped surfaces from inside to outside.
After the scheme is adopted, as the cutter head is provided with the arc-shaped cutter edge, the inclined plane cutter edge and the vertical plane cutter edge, a plurality of formed cutter edges are processed on the same cutter, the arc-shaped cutter edge is used for cutting an arc surface, the inclined plane cutter edge is used for chamfering, the vertical plane cutter edge is used for cutting a vertical plane, cutter replacement is not needed, the processing efficiency is improved, meanwhile, the concentricity of counter bores is ensured, and the cutter head has the advantages of high processing efficiency and high processing precision.
The existing processing of one piece requires time: the utility model can be used for machining a workpiece with the required machining time of 10 minutes/1 piece, one workpiece is shortened by 20 minutes, and the machining cost is saved by 2/3.
Compared with the traditional cutter with zero and regular cutting angle, the non-standard cutter has the advantages that the cutting angle is increased, the cutter is sharp, the deformation of a cutting layer and the friction resistance in front are small, the cutting force and the cutting temperature can be reduced, accumulated scraps can be restrained or eliminated, the product smoothness is improved, and the cutter mark is obvious in the traditional cutter processing. The utility model will be further described with reference to the drawings and the specific examples.
