Abstract
The utility model belongs to the cutting tool field and particularly relates to an integral hard alloy internal cooling drill bit which comprises a cutter handle and a cutting part which are integrally formed. A spiral cutting blade and an end face cutting blade of the front end face are arranged on the cutting part. The integral hard alloy internal cooling drill bit is characterized in that a cooling runner is arranged inside the cutter handle and the cutting part, one end of the cooling runner is arranged at the tail end of the cutter handle, and the other end of the cooling runner is arranged on the front end face of the cutting part. The integral hard alloy internal cooling drill bit is good in strength, can cool the cutting face timely, and improves cooling and cutting effects.
Description
Technical field
The utility model belongs to the cutting tool field, particularly a kind of interior cooling drill bit of all-in-one-piece carbide alloy.
Background technology
Drill bit is adding man-hour, the general nozzle that adopts cools off to processing place injection cooling fluid, and owing to the accumulation of drill bit in High Rotation Speed and smear metal, cooling fluid often can't enter into working position drill bit is cooled off, the effect of realization cooling fluid that can't be real also is unfavorable for the carrying out of processing.
Summary of the invention
For the deficiencies in the prior art, the utility model designed a kind of handle of a knife and cutting portion integrated, and in being provided with the carbide alloy of coolant flow channel, cutter inside cools off drill bit, intensity of the present utility model is good, and can cool off the cutting face timely, improve cooling effect and cutting effect.
The utility model is achieved through the following technical solutions:
Cooling drill bit in the whole hard alloy, it comprises integrated handle of a knife and cutting portion, be provided with the spiral cutting sword of spiral and the face cutting edge of front end face on the described cutting portion, it is characterized in that: described handle of a knife and cutting portion inside are provided with coolant flow channel, one end of coolant flow channel is positioned at the end of handle of a knife, and the other end is positioned on the front end face of cutting portion.
The angle of the face cutting edge of described cutting portion is 140 °.
In sum, handle of a knife of the present utility model and cutting portion adopt and are made of one piece, has preferably bulk strength, satisfy some high-intensity processing requests, inside of the present utility model is provided with coolant flow channel simultaneously, cutting fluid can directly be carried out Cooling and Lubricator to the cutting face by coolant flow channel, is conducive to prolong cutting-tool's used life, also is conducive to improve simultaneously cutting quality.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is coolant flow channel among the figure, and 2 are the spiral cutting sword, and 3 is cutting portion, and 4 is handle of a knife, and 6 is face cutting edge.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Cooling drill bit in the whole hard alloy as shown in Figure 1, it comprises integrated handle of a knife 4 and cutting portion 3, be provided with the spiral cutting sword 2 of spiral and the face cutting edge 6 of front end face on the described cutting portion 3, it is characterized in that: described handle of a knife 4 and cutting portion 3 inside are provided with coolant flow channel 1, one end of coolant flow channel 1 is positioned at the end of handle of a knife 4, and the other end is positioned on the front end face of cutting portion 3.
The angle of the face cutting edge 1 of described cutting portion 3 is 140 °.
In sum, handle of a knife of the present utility model and cutting portion adopt and are made of one piece, has preferably bulk strength, satisfy some high-intensity processing requests, inside of the present utility model is provided with coolant flow channel simultaneously, cutting fluid can directly be carried out Cooling and Lubricator to the cutting face by coolant flow channel, is conducive to prolong cutting-tool's used life, also is conducive to improve simultaneously cutting quality.
