Abstract
The invention discloses an internal cooling system for a cutting tool. The system comprises a tool bit and a tool bar, wherein an air inlet hole is formed in the tool bar; an air outlet hole is formed in the end surface, connected with a rake face located on the tool bit, of the tool bar; the air outlet hole and the air inlet hole are communicated in the tool bar; an air inlet valve is connected into the air inlet hole; a cooling air pipe is connected with the tail end of the air inlet valve; no less than 2 swirl spray holes communicated with the air inlet hole are formed in the air inlet valve; center lines of the swirl spray holes and an axis of the air inlet hole are staggered in space. According to the internal cooling system for the cutting tool, cooling air is adopted for cooling, so that scrap iron is not likely to adhere to a tool edge, the cooling air is sprayed to the tool edge of the tool bit in a swirl manner, the scrap iron is washed away, the tool edge is cooled more sufficiently, the cooling effect is good, the processing efficiency is high, and the service life of the cutting tool is long.
Description
Technical field
The invention belongs to the field of cutter with special chiller, be specifically related to a kind of cutter inner cooling but system.
Background technology
nullIn prior art，The cooling oil provided by lathe oil delivering unit is cooled down，During lathe work, machined workpiece rotates and boring head remains stationary as，Cause that cooling oil can not fully 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，Including 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 inlet，The front end face of described boring head end cap is provided with venthole，Described air inlet connects in described end cap with described venthole，It is big that this interior type of cooling easily causes fuel consumption，Venthole pressure hour，Cooling effect is poor，It is not easy to wash away iron filings，When venthole pressure is big，Easily cause cooling oil waste，And unnecessary cooling oil accumulates on the nose angle of the edge of a knife，Affect crudy.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of cutter inner cooling but system, this cutter inner cooling but system cools down by adopting cooling air, cooling air is carried out being injected in the knife-edge part of cutter head in the way of eddy flow, wash away iron filings, making iron filings not easily adhere at knife-edge part, make edge of a knife cooling more abundant, good cooling results, working (machining) efficiency are high, cutter life is long.
In order to achieve the above object, the present invention plants cutter inner cooling but system, including cutter head and knife bar, described knife bar is provided with air inlet, the end face that described knife bar is connected with the rake face being positioned on cutter head is provided with venthole, described venthole connects in described knife bar with described air inlet, it is connected to intake valve in described air inlet, described intake valve tail end is connected to cooling trachea, being provided with the swirl injection hole connected with air inlet no less than 2 on described intake valve, described swirl injection centerline hole is interlaced in space with air inlet axis.
Further, described air inlet 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 inlet centrage form the angle of 5 °～60 °.
Further, described swirl injection hole is set to 3 and is distributed on intake valve.

The beneficial effects of the present invention is:
Cutter inner cooling of the present invention but system cools down by adopting cooling air, cooling air is carried out being injected in the knife-edge part of cutter head in the way of eddy flow, washes away iron filings, make iron filings not easily adhere at knife-edge part, making edge of a knife cooling more abundant, good cooling results, working (machining) efficiency are high, cutter life is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of cutter inner cooling of the present invention but system；
Accompanying drawing labelling: 1-cutter head；2-knife bar；3-rake face；4-air inlet；6-venthole；7-intake valve；8-swirl injection hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
It is illustrated in figure 1 the structural representation of cutter inner cooling of the present invention but system；One cutter inner cooling but system of the present invention, including cutter head 1 and knife bar 2, described knife bar 2 is provided with air inlet 4, the end face that described knife bar 2 is connected with the rake face 3 being positioned on cutter head 1 is provided with venthole 6, described venthole 6 connects in described knife bar 2 with described air inlet 4, it is connected to intake valve 7 in described air inlet 4, described intake valve 7 tail end is connected to cooling trachea, being provided with the swirl injection hole 8 connected with air inlet 4 no less than 2 on described intake valve 7, described swirl injection hole 8 centrage is interlaced in space with air inlet 8 axis.
The present embodiment cooling air enters intake valve 7 by cooling down trachea, under the effect in swirl injection hole 8, cooling air is that cyclone type enters in air inlet 4, and is discharged by venthole 6, is sprayed onto the knife-edge part on cutter head 1, by adopting cooling air to cool down, cooling air is carried out being injected in the knife-edge part of cutter head 1 in the way of eddy flow, washes away iron filings, make iron filings not easily adhere at knife-edge part, making edge of a knife cooling more abundant, good cooling results, working (machining) efficiency are high, cutter life is long.
Further, it is preferred that described air inlet 4 is arranged on knife bar 2 tail end, this structure advantageously reduce eddy flow cooling air turn to.
Further, it is preferred that described swirl injection hole 8 is arranged on intake valve 7 body wall, this structure is conducive to improving the flow of cooling air, improves cooling effect, and the present embodiment swirl injection hole 8 can also be arranged on the front end of intake valve 7,
Further, it is preferred that described swirl injection centerline hole 8 and air inlet 4 centrage form the angle of 5 °～60 °, this structure is conducive to improving the eddy flow effect of eddy flow cooling air.
Further, it is preferred that described swirl injection hole 8 is set to 3 and is distributed on intake valve 7, this structure is conducive to the stability of eddy flow cooling air, it is to avoid the flow-rate fluctuation of eddy flow cooling air is indefinite.
Further, it is preferred that described air inlet 4 and venthole 6 have one or more respectively.
