Background technology
Carbide drill cutter, traditional technique carries out process of putting the first edge on a knife or a pair of scissors on solid pole; Drill bit is carrying out adding man-hour, and because drill bit needs High Rotation Speed, and the material hardness of processing is also higher, therefore because the effect of frictional force can produce a large amount of heats in process.Carbide alloy has good thermal conductivity, and the heat of generation can be delivered to rapidly on carbide drill cutter; But temperature is when reaching certain value, the performance of carbide alloy then can sharply decline, thus directly affects cutting effect and the service life of drill bit.
Now in the art, drill bit is carrying out adding man-hour, and the general nozzle that adopts carries out drill bit cooling to processing place injection cooling medium; But because drill bit is in the accumulation of High Rotation Speed and rapidoprint chip, cooling medium then often cannot enter into working position smoothly and cool drill bit, the effect of cooling medium cooling drill bit cannot be realized veritably, continuing of being unfavorable for processing carries out, and still just affects cutting effect and the service life of drill bit simultaneously.
Utility model content
Main purpose of the present utility model is, overcomes deficiency of the prior art, provides a kind of carbide drill cutter of new structure, is specially adapted to the large heat generation of frictional force in process many and need in time cooling drill bit to reduce the situation of temperature.
Technical problem to be solved in the utility model improves simple, easy to make, the practical a kind of carbide drill cutter of structure, when drill bit is carrying out adding man-hour, although the large heat generation of frictional force is many in process, drill bit can both be made to be cooled fully, in high temperature process, drill bit can guarantee that after its temperature significantly reduces cutting effect is good, processing continues efficient, extend the service life of drill bit simultaneously, and there is the value in industry.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of carbide drill cutter, comprises the consistent drill bit blade of central axis and drill handle part, the inside of described drill bit blade and drill handle part is provided with coolant guiding channel; Described coolant guiding channel one end is distributed in the end of drill handle part, and the other end is distributed in the inside of drill bit blade; Described drill bit blade axial surface offers to drill bit blade inside and the past Cooling Holes extended away from bit edge end surface; Described Cooling Holes and coolant guiding channel connect.
The utility model is set to further: described coolant guiding channel is 1, is arranged on the consistent inside center axis place of drill bit blade and drill handle part.
The utility model is further set to: the radial section of described coolant guiding channel is cylindrical.
The utility model is further set to: described in be distributed in the coolant guiding channel termination distance bit edge end surface of drill bit blade inside length be 1/5th of drill bit blade axial length.
The utility model is further set to: described Cooling Holes is uniformly distributed in emitting shape centered by coolant guiding channel; Described Cooling Holes radial dimension is less than coolant guiding channel radial dimension.
The utility model is further set to: described Cooling Holes central axis is acute angle with the crossing angle of coolant guiding channel central axis.
The utility model is further set to: described acute angle is 60 degree.
The utility model is further set to: described Cooling Holes is 6.
The utility model is further set to: the radial section of described Cooling Holes is cylindrical.
Compared with prior art, the beneficial effect that the utility model has is:
1, by being provided with coolant guiding channel in the inside of drill bit blade and drill handle part, and the Cooling Holes to connect with coolant guiding channel, carry out adding man-hour at drill bit, cooling medium successfully can be transported to high temperature process position, thus temperature of diamond bit is minimized, guaranteeing to process the cutting effect, the process that have presented continues efficient, and drilling life of bit extends.
2, described Cooling Holes is opened on drill bit blade axial surface, simultaneously to drill bit blade inside and toward extending away from bit edge end surface, and coolant guiding channel one end is distributed in the end of drill handle part, the other end is distributed in the inside of drill bit blade, such set-up mode can well avoid the blocking phenomenon of cooling medium to occur, thus guarantees effective continued down.
3, described radial section is the consistent inside center axis place that columniform coolant guiding channel is arranged on drill bit blade and drill handle part, 6 Cooling Holes are then uniformly distributed in emitting shape centered by coolant guiding channel, the comprehensive conveying of cooling medium can be realized, bit face is evenly lowered the temperature comprehensively, good cooling results, ensures that cutting effect is good.
Foregoing is only the general introduction of technical solutions of the utility model, and in order to clearer understanding technological means of the present utility model, below in conjunction with accompanying drawing, the utility model will be further described.
