Technical problem to be solved in the utility model improves simple, easy to make, practical a kind of of structure to cool adjustable carbide drill cutter, 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, extends the service life of drill bit; Meanwhile, methods for cooling and the adjustable measure of cooling in adopting, easy to adjust, economize energy, has the value in industry.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Cool an adjustable carbide drill cutter, comprise the consistent drill bit blade of central axis and drill handle part, at described drill bit blade, the consistent inside center axis place of 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.
Wherein, 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.
Simultaneously, described drill handle part outer wall is vertically installed with adjusting rod, stretch into after described adjusting rod one end passes perpendicularly through drill handle part coolant guiding channel with can the valve plate of switch coolant guiding channel be connected, the other end is connected with regulating handle after stretching out drill handle part outer wall.
The utility model is set to further: described in pass perpendicularly through drill handle part adjusting rod bar section be provided with sealing ring.
The utility model is set to further: the radial section of described valve plate and coolant guiding channel matches.
The utility model is set to further: described regulating handle is the wing nut be connected on adjusting rod.
The utility model is set to further: 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 set to further: described Cooling Holes is uniformly distributed in emitting shape centered by coolant guiding channel.
The utility model is set to further: described Cooling Holes central axis is acute angle with the crossing angle of coolant guiding channel central axis.
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, 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, coolant guiding channel is arranged on the consistent inside center axis place of drill bit blade and drill handle part, Cooling Holes is 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.
4, adopt in methods for cooling and cool adjustable measure, can the valve plate of switch coolant guiding channel by regulating nearby, be convenient to the adjustment supply of cooling medium needed for different process, while easy to adjust, save the cooling medium energy, avoid waste.
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.
