The beneficial effects of the utility model are:
In the utility model cutter, oil gas cooling system is by adopting cooling-air and the well-mixed mode of cooling fluid, by the knife-edge part of cold oil gas jet at 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 oil gas cooling system in the utility model cutter;
Reference numeral: 1-cutter head; 2-knife bar; 3-rake face; 4-air admission hole; 5-fuel feed hole; 6-oil outlet; 7-intake valve; 8-swirl injection hole; 9-air-fuel mixture room.
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 oil gas cooling system in the utility model cutter; Oil gas cooling system in a kind of cutter of the utility model, comprise cutter head 1 and knife bar 2, described knife bar 2 is provided with fuel feed hole 5 and air admission hole 4, the end face that described knife bar 2 is connected with cutter head 1 rake face 3 is provided with oil outlet 6, be provided with the air-fuel mixture room 9 be communicated with fuel feed hole 5 with air admission hole 4 in described knife bar 2, described oil outlet 5 is communicated with in described knife bar 2 with described air-fuel mixture room 9.
The present embodiment cooling-air enters in air-fuel mixture room 9 by cooling tracheae, air admission hole 4, cold oil enters air-fuel mixture room 9 by fuel feed hole 5 simultaneously with it, after cooling-air and cold oil mix in air-fuel mixture room 9, and discharged by venthole 6, be sprayed onto the knife-edge part on cutter head 1, by adopting cooling-air and the well-mixed mode of cooling fluid, by the knife-edge part of cold oil gas jet at 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.
Further, preferred described air admission hole 4 is arranged on knife bar 2 tail end, and this structure is conducive to reducing cooling-air and turns to.
Further, intake valve 7 is connected with in preferred described air admission hole 4, described intake valve 7 tail end is connected with cooling tracheae and its forward end stretched in air admission hole is set to taper, and this structure is conducive to improving the pressure that intake valve 7 exports cooling-air, improves cooling effect.
