Abstract

The utility model provides a concave forming ring groove cutter, comprising: the cutter comprises a cutter head and a handle part, wherein the cutter head is composed of two opposite V-shaped structures, a V-shaped annular groove composite cutting edge is formed at the intersection of the two V-shaped structures, and an outer cutting edge is arranged at the edge of the two V-shaped structures. Through the mode, the problem that the common cutter of the existing special structural part cannot be machined is solved.

Description

Indent shaping annular groove cutter

Technical Field

The utility model relates to the field of machining, in particular to a concave forming ring groove cutter.

Background

As shown in figure 1, the component is a special structure part, the inner tip of the component at 68 degrees is difficult to select a proper machining mode for finishing, the hole of D15 is difficult to machine due to the existence of the tip cone, and at present, a common cutter cannot machine the structure.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a concave forming ring groove cutter, which solves the problem that the existing common cutter for parts with special structures cannot process.

The main content of the utility model comprises: a female forming ring groove cutter, comprising: the cutter comprises a cutter head and a handle part, wherein the cutter head is composed of two opposite V-shaped structures, a V-shaped annular groove composite cutting edge is formed at the intersection of the two V-shaped structures, and an outer cutting edge is arranged at the edge of the two V-shaped structures.

Preferably, the outer sides of the two V-shaped structures form chip flutes.

Preferably, a chip groove is arranged behind the chip groove.

Preferably, the junction of the two V-shaped structures with the shank is provided as a taper angle.

Preferably, the handle part is provided with an inwards concave side fixing surface.

Preferably, the front end faces of the two V-shaped structures are provided with end teeth.

By adopting the structure of the utility model, the workpiece shown in figure 1 can be processed, the design of the V-shaped annular groove composite cutting edge is convenient for processing a 68-degree inner tip, and an outer cutting edge at the edge is used for processing a hole D15.

The cutter is formed by grinding the forming grinding wheel except the front end face, the strength of the cutting edge is ensured to be enough under the condition that the cutting edge is sharp enough, after the forming grinding wheel is matched for edging, the whole 68-degree cutting edge is very uniform, the cutting stress is relatively uniform during processing, the roughness quality of the whole surface is better, and the service life is prolonged.

Detailed Description

The technical scheme protected by the utility model is specifically explained in the following by combining the attached drawings.

As shown in fig. 2 and 3, a concave forming ring groove cutter comprises: the tool bit comprises a tool bit body and a handle part 2, wherein the tool bit body is composed of two opposite V-shaped structures, a V-shaped annular groove composite cutting edge 12 is formed at the intersection of the two V-shaped structures, and an outer cutting edge 11 is arranged at the edge of the two V-shaped structures. The V-shaped annular groove compound cutting edge 12 is used for machining a 68-degree inner tip, and the outer cutting edge 11 at the edge is used for machining a hole D15. The V-shaped angle of the V-shaped annular groove composite cutting edge 12 is set to be 68 degrees, and is the same as the angle of the inner vertex. The outer edges 11 at the four edges improve the strength of the tool.

Further, in order to facilitate the discharge of the chips in time, the outer sides of the two V-shaped structures form chip flutes 14. The chip pocket 14 has a large space and is connected to the chip pocket 15 at the rear, thereby enabling the chips to be discharged quickly.

Further, the junction of the two V-shaped structures with the handle 2 is provided as a taper angle 16. A stepped internal chamfer for chip D15 hole. The function of processing a plurality of structures by one cutter is realized, and the application range of the cutter is enlarged.

Finally, the handle 2 is provided with an inward concave side fixing surface 21. The side fixing surface 21 can be a plane or an arc with the radian smaller than the outer circumference of the handle part 2, so that the clamping force of the handle part is improved, and the clamping is more convenient.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
