Description
Technical field
The present invention relates to a kind of carbide drill cutter, particularly relate to a kind of interior cooling carbide drill cutter, belong to machinery knives technical field.
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.
In prior 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 carry out effective cooling to 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.And adopting nozzle to carry out drill bit cooling to processing place injection cooling medium needs the external world to provide cooling medium, and such as cooling water, exists the problem of direct energy source waste always.
Summary of the invention
Main purpose of the present invention is, overcomes deficiency of the prior art, provide a kind of in cooling carbide drill cutter, be specially adapted to the large heat generation of frictional force in process many and need cooling drill bit in time to reduce the situation of temperature of diamond bit.
Technical problem to be solved by this invention improves cooling carbide drill cutter in simple, easy to make, the practical one 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 obtain abundant effective cooling, in high temperature process, drill bit can guarantee that after its temperature significantly reduces cutting effect is good, processing continues efficient, extends the service life of drill bit; Meanwhile, adopt interior methods for cooling and cancel the without interruption of extraneous cooling medium, economize energy, has the value in industry.
In order to achieve the above object, the technical solution adopted in the present invention is:
In a kind of, cooling 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 cooling tube.
Wherein, absorption heat transfer medium is filled with in the hollow reservoir of described cooling tube; The closed at both ends of described cooling tube, the inside that one end is distributed in the end of drill handle part, the other end is distributed in drill bit blade; The described length being distributed in the cooling tube termination distance bit edge end surface of drill bit blade inside is 1/5th of drill bit blade axial length.
Meanwhile, described drill handle part outer wall is provided with louvre, described louvre extends, only extends to the outer wall end of cooling tube tube wall to drill handle part inside.
The present invention is set to further: described louvre is evenly distributed on drill handle part outer wall one week centered by cooling tube axis.
The present invention is set to further: described louvre is rectangular slotted eye.
The present invention is set to further: described louvre is 3.
The present invention is set to further: described cooling tube is 1, is arranged on the consistent inside center axis place of drill bit blade and drill handle part.
The present invention is set to further: the radial section of described cooling tube is for circular.
Compared with prior art, the beneficial effect that the present invention has is:
1, by arranging cooling tube in the inside of drill bit blade and drill handle part, and in the hollow reservoir of cooling tube, be filled with absorption heat transfer medium, and the setting of louvre, carry out adding man-hour at drill bit, rapidly and efficiently thermal energy conduction can be carried out by the cholesteric-nematic transition of heat transfer medium absorption in cooling tube, the heat at high temperature process position is successfully spread out rapidly, thus temperature of diamond bit is minimized, guaranteeing to process the cutting effect, the process that have presented continues efficient, and the service life of drill bit is extended.
2, the interior methods for cooling being filled with the cooling tube of absorption heat transfer medium is adopted, and cancel the without interruption of extraneous cooling medium, conventional spray cooling medium can well be avoided to occur to the blocking phenomenon at drill bit place, thus guarantee effective continued down, simultaneously, can economize energy, reduce costs.
3, the louvre extending to cooling tube tube wall outer wall end of rectangular slotted hole structure is adopted, and louvre is evenly distributed on drill handle part outer wall one week centered by cooling tube axis, can realize cooling tube conduct that the heat transferred out is comprehensive to be dispelled the heat smoothly fast, bit face is evenly lowered the temperature comprehensively, good cooling results, also ensures that cutting effect is good.
Foregoing is only the general introduction of technical solution of the present invention, and in order to clearer understanding technological means of the present invention, below in conjunction with accompanying drawing, the invention will be further described.
