Abstract
The utility model provides a hard alloy drill bit, which comprises a drill body, a hard alloy drill sheet, a water hole and a flute. The utility model is characterized in that the flute is arranged in a sloping mode toward a centerline of the drill body. Debris of sand and stones in the drill bit of the structure can be discharged backwards automatically with the rotary drilling of the drill bit. Therefore, the drill resistance can be reduced and the drill efficiency can be increased. Meanwhile, because the abrasion of the drill bit is reduced, the service life of the drill bit can be prolonged.
Description
Technical field
The utility model relates to a kind of bore bit, particularly a kind of hard alloy drill that is used for mine, geology, oil, water conservancy, highway and the use of railway construction engineering.
Background technology
The chip area of existing hard alloy drill generally all is along the setting of pricker body center line, and bore bit is in drilling process, because the bore bit rotation very easily causes silt to stop up, makes bore bit creep into difficulty, and drilling efficiency is low; Because silt is difficult for discharging, the bore bit serious wear is caused scrap simultaneously, greatly shortened the application life of bore bit.
The utility model content
The purpose of this utility model is to provide a kind of hard alloy drill, and this kind bore bit can overcome the defective that prior art exists, and reaches the raising drilling efficiency, prolongs the purpose of service life of the bits.
Solution of the present utility model is that this kind hard alloy drill comprises pricker body, brazing sheet of hard alloy, hydrophthalmia, chip area, it is characterized in that chip area is obliquely installed with respect to pricker body center line.
Above-mentioned chip area angle of slope can be made as 10～30 degree.
Advantage of the present utility model is that chip area is obliquely installed with respect to bore bit main center line, along with the drill bit rotary drilling, the sandstone chip can automatically be discharged backward, therefore can reduce and creep into resistance, improve drilling efficiency, owing to reduced the bore bit wearing and tearing, therefore prolonged the application life of bore bit simultaneously.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, hydrophthalmia; 2, brazing sheet of hard alloy; 3, chip area; 4, pricker body.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
Embodiment one
With HY3040 type bore bit is example explanation: pricker body 4 diameter 40mm, and length 68mm, chip area 3 radius 32.5mm are 16 degree with respect to the angle of slope of pricker body 4.
Embodiment two
With HY3042 type bore bit is example explanation: pricker body 4 diameter 42mm, and length 68mm, chip area 3 radius 32.5mm are 18 degree with respect to the angle of slope of pricker body 4.
Claims (2)
1, a kind of hard alloy drill comprises pricker body, brazing sheet of hard alloy, hydrophthalmia, chip area, it is characterized in that chip area is obliquely installed with respect to pricker body center line.
2, bore bit according to claim 1 is characterized in that described chip area angle of slope can be made as 10～30 degree.
