Abstract
The utility model discloses a carbide profile milling cutter in processing back taper hole, profile milling cutter includes: the stalk portion, and head, be equipped with the heliciform cutting edge more than two on the head, the outer peripheral face of head is close to for the tip the toper of stalk portion, just the inclination of the outer peripheral face of head with the inclination in back taper hole is unanimous. The utility model discloses a carbide profile milling cutter in processing back taper hole through the CNC process of head to the back taper hole, replaces EDM processing technology, can effectual improvements machining efficiency 50%, shorten mould processing cycle 50%, and reduction mould processing cost 30%.
Description
Technical field
The utility model relates to milling cutter, particularly relates to a kind of carbide alloy profile milling cutter processing reverse taper hole.
Background technology
Figure 1 shows that the structural representation of the reverse taper hole 20 of model, the processing method of this reverse taper hole 20, all cannot complete processing with the cylindrical cutting tool of routine in CNC operation from front or reverse side, EDM spark machined can only be adopted.Because EDM processing needs design electrode, buying electrode material, machined electrode, processes the reverse taper hole of this model again with electrode in EDM design, therefore the process-cycle is long, and efficiency is low, and cost is high.
Summary of the invention
For above-mentioned prior art present situation, the utility model provides a kind of carbide alloy profile milling cutter processing reverse taper hole, solves high, the inefficient technical problem of the cost brought that reverse taper hole can only adopt EDM operation to process.
In order to solve the problems of the technologies described above, a kind of carbide alloy profile milling cutter processing reverse taper hole provided by the utility model, described profile milling cutter comprises:
Shank; With
Head, described head is provided with the helical cutting edge of more than two;
The outer peripheral face of described head is the taper of small end near described shank, and the gradient of the outer peripheral face of described head is consistent with the gradient of described reverse taper hole.
Wherein in an embodiment, described cutting edge is four.
Wherein in an embodiment, described shank and described head one-body molded.
Wherein in an embodiment, described shank comprises:
Clamping shank; With
Empty avoiding shank, described empty avoiding shank is connected between described clamping shank and described head, and the external diameter of described empty avoiding shank is less than the external diameter of described clamping shank.
Wherein in an embodiment, the external diameter of described empty avoiding shank is equal with the external diameter of described head small end.
The carbide alloy profile milling cutter of processing reverse taper hole of the present utility model, outer peripheral face due to head is the taper of small end near shank, and the gradient of the outer peripheral face of head and the gradient of reverse taper hole consistent, by head, the CNC operation of reverse taper hole is processed, replace EDM processing technology, can effectively improve working (machining) efficiency 50%, shorten the Mould Machining cycle 50%, reduce Mould Machining cost 30%.
The beneficial effect that the utility model additional technical feature has will be described in this description detailed description of the invention part.

Detailed description of the invention
And the utility model is described in detail below with reference to the accompanying drawings in conjunction with the embodiments.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
As shown in Figure 2, the carbide alloy profile milling cutter of the processing reverse taper hole in one of them embodiment of the utility model comprises: shank 11 and head 12, wherein, the outer peripheral face of described head 12 is the taper of small end near described shank 11, and the gradient of the outer peripheral face of described head 12 is consistent with the gradient of described reverse taper hole.By this profile milling cutter, on CNC numerical control machining center, directly can process reverse taper hole, replace EDM processing technology, thus solve high, the inefficient problem of EDM processing technology cost.More preferably, described cutting edge 12a is four.More preferably, described shank 11 and described head 12 one-body molded.
More preferably, described shank 11 comprises clamping shank 11a and empty avoiding shank 11b, and described empty avoiding shank 11b is connected between described clamping shank 11a and described head 12, and the external diameter of described empty avoiding shank 11b is less than the external diameter of described clamping shank 11a.More preferably, the external diameter of described empty avoiding shank 11b is equal with the external diameter of described head 12 small end.Empty avoiding shank 11b is used for preventing described head 12 from interfering with reverse taper hole.
Fig. 3 is the using state figure of the carbide alloy profile milling cutter of processing reverse taper hole in the utility model embodiment.The profile milling cutter of the utility model embodiment can use on CNC numerical control machining center, fine finishining model reverse taper hole, reach quick, high-precision, low cost processing effect.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
