Description

Forming milling cutter for simultaneously processing hole and groove

Technical Field

The utility model relates to the field of machining, in particular to a formed milling cutter for simultaneously machining holes and grooves.

Background

When machining, for parts which are complex in shape of machining positions, high in requirements on the machined hole diameter and high in requirements on form and position tolerance, the size requirements of the parts are difficult to achieve by using common standard cutters, and proper turning tools are difficult to select.

Moreover, when the material of the part is difficult to process, especially the drilling cutter and the grooving cutter are needed to be used for secondary processing and forming on similar parts, and the common standard cutter is used, the processing time is long, and the specification of the drilling cutter needs to be changed when the aperture changes, so that the tool cost is increased.

The main content of the utility model comprises: a formed milling cutter for simultaneously processing holes and grooves mainly comprises: a tool bit and a shank, the tool bit including a plurality of cutting edge sets evenly disposed along an outer circumference, each cutting edge set including: the end tooth of tip, the protruding first peripheral sword that sets up in end tooth rear, set up in first peripheral sword rear and the external diameter is less than the second peripheral sword of first peripheral sword.

Preferably, an inclined tapered edge is provided between the first peripheral edge and the second peripheral edge.

Preferably, adjacent first peripheral edges have chip flutes formed therebetween.

Preferably, a chip groove is formed behind the chip groove and communicated with the chip groove.

Preferably, a fillet is provided between the first peripheral edge and the end tooth.

Preferably, a plurality of internal cooling holes are formed in the chip groove and communicated with the central hole of the handle.

Preferably, the first peripheral edge and the second peripheral edge are both arranged in a conical structure with a high middle and gradually reduced two sides, and two sides of the cutting edge form a knife back.

The utility model has the beneficial effects that:

1. the cutter designs a plurality of cutting edges according to the size of the forming groove, and the forming groove can be processed and formed at one time;

2. the cutter blade is connected, can process part aperture size in the time of processing the shaping groove, and machining efficiency is high, the precision is high to can process different apertures simultaneously according to the change in aperture.

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. 1 to 4, a milling cutter for simultaneously processing a hole and a groove mainly includes: a bit comprising six cutting edge sets evenly disposed along an outer circumference, each cutting edge set comprising: the end tooth 11 of the end portion, the first peripheral edge 12 that is provided to protrude rearward of the end tooth 11, and the second peripheral edge 13 that is provided rearward of the first peripheral edge 12 and has an outer diameter smaller than that of the first peripheral edge 12. The length of the first peripheral edge 12 is short, the first peripheral edge is mainly used for processing the hole diameter, the length of the second peripheral edge 13 is long, the second peripheral edge is used for processing the forming groove, the excessive tapered edge 14 is arranged between the first peripheral edge 12 and the second peripheral edge 13, so that the two peripheral edges are connected, the hole diameter size of a part can be processed while the forming groove is processed, the processing efficiency is high, the precision is high, and different hole diameters can be processed simultaneously according to the change of the hole diameter.

In order to facilitate the timely discharge of the cutting chips, chip flutes 15 are formed between adjacent first peripheral edges, and chip flutes 16 are arranged behind the chip flutes 15, wherein the chip flutes 16 are communicated with the chip flutes 15.

Furthermore, a plurality of internal cooling holes 19 are formed in the chip removal groove 16, and the plurality of internal cooling holes 19 are communicated with the central hole of the handle part, so that the chip removal performance of the cutter during machining is effectively enhanced, and the heat generated during cutting is reduced.

The first peripheral edge 12 and the second peripheral edge 13 are both set to be of a conical structure with a high middle part and two sides gradually reduced, the two sides of the cutting edge form a knife back 18, and the strength of the cutting edge is enhanced by adopting the conical knife edge structure.

And a fillet 17 is formed between the first peripheral edge 12 and the end tooth 11, so that abrasion at the edge corner is avoided, and the part can be prevented from being scratched.

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.
