Description
Technical field
The utility model belongs to the field of the cutter being with special cooling device, specifically relates to a kind of cutter inner cooling but system.
Background technology
In prior art, the cold oil provided by lathe oil delivering unit is cooled, the workpiece processed during lathe work rotates and boring head keeps motionless, cold oil is caused fully not water on cutter, boring machine stock-removing efficiency is caused to reduce, limit the service life of the edge of a knife simultaneously, Chinese patent CN103611958A description discloses a kind of cutter inner cooling but system, comprise boring head, boring bar, the front portion of described boring head is provided with boring head end cap, the rear end face of described boring head end cap is provided with air admission hole, the front end face of described boring head end cap is provided with venthole, described air admission hole is communicated with in described end cap with described venthole, this interior type of cooling easily causes fuel consumption large, venthole pressure hour, cooling effect is poor, be not easy to wash away iron filings, when venthole pressure is large, cold oil is easily caused to waste, and unnecessary cold oil accumulates on the nose angle of the edge of a knife, affect crudy.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of cutter inner cooling but system, this cutter inner cooling but system cools by adopting cooling-air, cooling-air is carried out in the mode of eddy flow the knife-edge part being injected in cutter head, wash away iron filings, iron filings are not easily adhered at knife-edge part, and the edge of a knife is cooled more abundant, good cooling results, working (machining) efficiency are high, cutter life is long.
In order to achieve the above object, the utility model kind cutter inner cooling but system, comprise cutter head and knife bar, described knife bar is provided with air admission hole, the end face that described knife bar is connected with the rake face be positioned on cutter head is provided with venthole, described venthole is communicated with in described knife bar with described air admission hole, intake valve is connected with in described air admission hole, described intake valve tail end is connected with cooling tracheae, described intake valve is provided with and is no less than 2 swirl injection holes be communicated with air admission hole, described swirl injection centerline hole and air admission hole axis interlaced in space.
Further, described air admission hole is arranged on knife bar tail end.
Further, described swirl injection hole is arranged on intake valve body wall.
Further, described swirl injection centerline hole and air admission hole center line form the angle of 5 ° ~ 60 °.

Further, described air admission hole and venthole have one or more respectively.
The beneficial effects of the utility model are:
The utility model cutter inner cooling but system cools by adopting cooling-air, cooling-air is carried out in the mode of eddy flow the knife-edge part being injected in cutter head, wash away iron filings, iron filings are not easily adhered at knife-edge part, the edge of a knife is cooled more abundant, good cooling results, working (machining) efficiency are high, cutter life is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model cutter inner cooling but system;
Reference numeral: 1-cutter head; 2-knife bar; 3-rake face; 4-air admission hole; 6-venthole; 7-intake valve; 8-swirl injection hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Be illustrated in figure 1 the structural representation of the utility model cutter inner cooling but system; A kind of cutter inner cooling of the utility model but system, comprise cutter head 1 and knife bar 2, described knife bar 2 is provided with air admission hole 4, the end face that described knife bar 2 is connected with the rake face 3 be positioned on cutter head 1 is provided with venthole 6, described venthole 6 is communicated with in described knife bar 2 with described air admission hole 4, intake valve 7 is connected with in described air admission hole 4, described intake valve 7 tail end is connected with cooling tracheae, described intake valve 7 is provided with and is no less than 2 swirl injection holes 8 be communicated with air admission hole 4, described swirl injection hole 8 center line and air admission hole 8 axis interlaced in space.
The present embodiment cooling-air enters intake valve 7 by cooling tracheae, under the effect in swirl injection hole 8, cooling-air is that cyclone type enters in air admission hole 4, and is discharged by venthole 6, is sprayed onto the knife-edge part on cutter head 1, cool by adopting cooling-air, cooling-air is carried out in the mode of eddy flow the knife-edge part being injected in cutter head 1, washes away iron filings, iron filings are not easily adhered at knife-edge part, the edge of a knife is cooled more abundant, good cooling results, working (machining) efficiency are high, cutter life is long.
Further, preferred described air admission hole 4 is arranged on knife bar 2 tail end, and this structure is conducive to reducing eddy flow cooling-air and turns to.
Further, preferred described swirl injection hole 8 is arranged on intake valve 7 body wall, and this structure is conducive to the flow improving cooling-air, and improve cooling effect, the present embodiment swirl injection hole 8 can also be arranged on the front end of intake valve 7,
Further, preferred described swirl injection centerline hole 8 and air admission hole 4 center line form the angle of 5 ° ~ 60 °, and this structure is conducive to the eddy flow effect improving eddy flow cooling-air.
Further, preferred described swirl injection hole 8 is set to 3 and is distributed on intake valve 7, and this structure is conducive to the stability of eddy flow cooling-air, avoids the flow-rate fluctuation of eddy flow cooling-air indefinite.
Further, preferred described air admission hole 4 and venthole 6 have one or more respectively.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
