Abstract
The utility model discloses a kind of drill bit, comprise brill body, the top of described brill body is drill bit, flight is provided with around described brill body, the inside of described brill body is provided with cooling tube vertically, described cooling tube is evenly distributed with Cooling Holes, and described Cooling Holes communicates with outside, and described cooling tube is connected with cooling source of the gas.The utility model is by being provided with cooling tube vertically in the inside of boring body, and cooling tube is evenly distributed with Cooling Holes, and Cooling Holes communicates with outside, cooling tube is connected with nitrogen, because the temperature of nitrogen is lower, the effect of cooling fast can be reached, and do not affect the discharge of chip.
Description
Technical field
The utility model relates to a kind of drill bit, belongs to machinework technical field.
Background technology
Drill bit is widely used as hole instrument, and drill bit arranges cutting edge in axial front end, and arranges chip discharging grooves at direction of principal axis, by rotating around axle center, carries out machining by the cutting edge of front end, and by chip discharging grooves by chip discharge.In working angles, when cooling cutter head, because chip area needs ceaselessly to carry out chip removal process, cooling fluid is not easy the position entering into point of a knife, and make corner wear very fast, and cooling is comparatively slow, cooling effect is poor.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is, provides a kind of drill bit, can be cooled fast by drill bit in chip process.
The technical solution of the utility model is: a kind of drill bit, comprise brill body, the top of described brill body is drill bit, flight is provided with around described brill body, it is characterized in that, the inside of described brill body is provided with cooling tube vertically, and described cooling tube is evenly distributed with Cooling Holes, described Cooling Holes communicates with outside, and described cooling tube is connected with cooling source of the gas.
Aforesaid a kind of drill bit, is characterized in that, described cooling source of the gas is nitrogen.
Aforesaid a kind of drill bit, is characterized in that, described cooling source of the gas is provided with control valve.
Aforesaid a kind of drill bit, is characterized in that, is provided with chip area between described flight, is provided with chip-removal hole in described chip area, and described chip-removal hole communicates with described Cooling Holes.
Aforesaid a kind of drill bit, is characterized in that, the material of described drill bit is metal.
Aforesaid a kind of drill bit, is characterized in that, the material of described drill bit is alloy.
The beneficial effect that the utility model reaches: by being provided with cooling tube vertically in the inside of boring body, cooling tube is evenly distributed with Cooling Holes, Cooling Holes communicates with outside, cooling tube is connected with nitrogen, because the temperature of nitrogen is lower, the effect of cooling fast can be reached, and do not affect the discharge of chip.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of drill bit, comprise and bore body 1, the top of described brill body 1 is drill bit 2, be provided with flight 3 around described brill body 1, the inside of described brill body 1 is provided with cooling tube 4 vertically, and described cooling tube 4 is evenly distributed with Cooling Holes 5, described Cooling Holes 5 communicates with outside, and described cooling tube 4 is connected with cooling source of the gas 6.
Preferably, described cooling source of the gas 6 is nitrogen, and nitrogen temperature is lower, good cooling results.
Preferably, described cooling source of the gas 6 is provided with control valve 7, controls flow and the time of nitrogen.
Preferably, be provided with chip area, be provided with chip-removal hole in described chip area between described flight 3, described chip-removal hole communicates with described Cooling Holes 5, does not affect the discharge of chip while cooling.
Preferably, the material of described drill bit 1 is alloy, prevents drill bit 2 from wearing and tearing.
The beneficial effect that the utility model reaches: by being provided with cooling tube vertically in the inside of boring body, cooling tube is evenly distributed with Cooling Holes, Cooling Holes communicates with outside, cooling tube is connected with nitrogen, because the temperature of nitrogen is lower, the effect of cooling fast can be reached, and do not affect the discharge of chip.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
Claims (6)
