Description

Stainless steel inner R highlight forming knife

Technical Field

The utility model relates to the technical field of numerical control machining, in particular to a stainless steel inner R highlight forming cutter.

Background

The forming cutter is used for processing the place which can not be processed or can not be processed in place by a common milling cutter, for example, when a reverse R angle is processed, an arc forming cutter is needed for processing.

However, in most cases, the forming cutter is made into a straight groove shearing angle four-edge form, the contact resistance point of the cutting edge is too large, the cutter vibration phenomenon is caused due to unsmooth cutting, and the product is easy to generate cutter lines.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a stainless steel inner R highlight forming cutter, which aims to solve the problems that the contact resistance point of the cutting edge of the traditional forming cutter is too large, the cutter vibration phenomenon is caused when the cutting is not smooth, and the cutter line is easy to generate on the product.

In order to achieve the purpose, the utility model provides the following technical scheme: r highlight shaping sword in stainless steel, including the handle of a knife with set up in the tool bit of handle of a knife one end, the handle of a knife with the axis coincidence of tool bit, the tool bit shaping has the cutting edge of spiral petal shape, the cutting edge is the arc from top to tail end, the side edge of cutting edge is provided with the blade, and is adjacent the shaping has the cutting groove between the cutting edge.

Preferably, one end of the tool bit is provided with a vertex angle.

Preferably, five cutting edges are uniformly distributed on the cutter head.

Preferably, the cutting groove is of an arc groove structure, and extends to the side wall of the cutter head and is opened to the tail end.

Preferably, the cutting edge has a clearance angle of 45 °.

Preferably, the length of the cutting groove is 7 mm.

Compared with the prior art, the utility model has the beneficial effects that:

by adopting the structure of the arc tooth gap, the utility model has the advantages of more wear resistance in processing stainless steel, good retentivity, inhibition of generation of vibration lines and cutter lines, longer usable time, elimination of grinding action behind a client, and capability of ensuring strength and having smoother chip removal and larger space.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: r highlight shaping sword in stainless steel, including handle of a knife 10 with set up in the tool bit 20 of handle of a knife 10 one end, handle of a knife 10 is SUS316 stainless steel preparation with tool bit 20 and forms, the axis coincidence of handle of a knife 10 and tool bit 20, tool bit 20 shaping has spiral petal shape's cutting edge 23, cutting edge 23 is the arc from top to tail end, cutting edge 23's side is along being provided with blade 24, the shaping has cutting groove 21 between the adjacent cutting edge 23.

In this embodiment, specifically, five cutting edges 23 are uniformly distributed on the tool tip 20.

Furthermore, by adopting the structure of the arc tooth gaps, the arc curvature of the cutting edge needs to be well controlled, so that the cutting edge has better supporting force, and the cutting capability is ensured while effective vibration resistance can be obtained.

Wherein, one end of the tool bit 20 is provided with a vertex angle 22.

In the present embodiment, specifically, the clearance angle of the cutting edge 23 is 45 °.

The cutting groove 21 is of an arc groove structure, and the cutting groove 21 extends to the side wall of the cutter head 20 and opens to the tail end.

In this embodiment, the length of the cutting groove 21 is 7 mm.

Furthermore, the current straight groove is converted into a groove shape with a smooth arc, the stress of a contact point can be dispersed during processing, backward rows are cut, the extrusion deformation of a product caused by the front rows is prevented, and the service life and the stability of the cutter are better improved.

The working principle is as follows: when the tool is used, the current straight groove is converted into a groove shape with a smooth arc, the stress of a contact point can be dispersed during processing, backward rows are cut, the extrusion deformation of a product caused by the front rows is prevented, and the service life and the stability of the tool are better improved.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
