Description
Technical field
The utility model patent relates to a kind of drill bit of cutting, relates in particular to a kind of anti-blocking structure of chip removal pore of cut drill.
Background technology
Present known cut drill, cut drill as shown in Figure 1 are connected the drilling rod bottom of hollow, offer drill bit flywheel moment and downforce by drilling rod, drive drill bit and on rock, do the motion that revolution presses down; The drill bit bottom is welded with drill edge, and under the motion that the revolution of drill bit presses down, drill edge cuts broken cutting particle on rock; Simultaneously; The drilling rod inside of hollow provides the compressed air of flow direction to drill bit; Compressed air is discharged, is carried in cutting hole that the cutting particle forms from rock and the annular gap between drilling rod through the drill bit steam vent and discharges outside the cutting hole; Under the reciprocating of above drill bit, on rock, form the cutting hole of constantly deepening.
Present known cut drill, as shown in Figure 2, the drill bit front portion is the cylinder of diameter D1, the drill bit rear end is the cylinder (D1＞D2) of diameter D2; Cylinder front end at the anterior diameter D1 of drill bit is welded with drill edge; Simultaneously; Cylindrical circumferencial direction at the anterior diameter D1 of drill bit; Be furnished with the flute of drill of diagram dash area, chip area is used to link up the drill edge place to space, drill bit rear end (this space is: the D2 outside is inboard to D1, the space that forms at the drill bit rear portion); In flute of drill, be furnished with the drill bit steam vent.As shown in Figure 3; When cutting drill bit open along the plane P of parallel drill bit rotation and the optional position through the drill bit steam vent; Form as diagram " section that plane P forms on cut drill ", drill bit steam vent outer and plane P intersect formation downside point A, upside point B; Line forms angle a with crossing the vertical line F that A order between A, B, and angle a spends less than 180 greater than 90 degree.
When running into moisture clay parting, because clay intensity is lower, drill bit can be pushed fast gets into clay; A large amount of clay cutting particles can not be compressed air and carry out fast outside the cutting hole, at this moment, because angle a is greater than 90 degree; Less than 180 degree; The clay that A is ordered meeting as shown in Figure 3 along vertical line F upwards arrives between the C point and B point in the drill bit steam vent passage, along with the discharge that can block air that increases of clay between C point and B point; Need the clay in labor cleaning's steam vent, thereby influence operating speed.
Summary of the invention
The utility model mainly is through the position of the steam vent that changes drill bit and the device of flute of drill, thereby when in the bore operation process, running into clay, prevents that clay from blocking the cut drill of the steam vent of drill bit.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of anti-blocking structure of chip removal pore of cut drill; Comprise drill body, described drill body is made up of drill body rear portion and drill body front portion, and described drill body is provided with axis hole in the rear portion; Described drill body is provided with cutting mechanism in the front portion; Described cutting mechanism comprises drill edge, flute of drill and drill bit steam vent passage, and described flute of drill is positioned at the anterior sidewall of drill body, and the bottom of described flute of drill is provided with drill edge; The inwall of described flute of drill is provided with drill bit steam vent passage; Described drill bit steam vent passage is connected with the axis hole at drill body rear portion, and the top of described flute of drill extends to the anterior upper end sidewall of drill body, and the below of described drill bit steam vent passage is a standing shape.
As shown in Figure 4, the drill bit front portion is the cylinder of diameter D1, and the drill bit rear end is the cylinder (D1＞D2) of diameter D2; Cylinder front end at the anterior diameter D1 of drill bit is welded with drill edge; Simultaneously; Cylindrical circumferencial direction at the anterior diameter D1 of drill bit; Be furnished with the flute of drill of dash area as shown in the figure, chip area is used to link up the drill edge place to space, drill bit rear end (this space is: the D2 outside is inboard to D1, the space that forms at the drill bit rear portion); In flute of drill, be furnished with the drill bit steam vent.As shown in Figure 5; Cut drill bit when reaching open through the plane P of drill bit steam vent optional position along parallel drill bit rotation; Form " section that plane P forms on cut drill " as shown in the figure, drill bit steam vent outer and plane P intersect the some A that forms downside, the some B of upside; The vertical line F that line and mistake A are ordered between A, B forms angle a, and angle a is greater than 180 degree.When running into moisture clay parting; Because clay intensity is lower, drill bit can be pushed fast gets into clay, and a large amount of clay cutting particles can not be compressed air and carry out outside the cutting hole fast; At this moment; The clay that A is ordered meeting as shown in Figure 5 is upwards pushed along vertical line F and is arrived space, drill bit rear end (this space is: the D2 outside is inboard to D1, in the space of drill bit rear portion formation), can not form clay in the drill bit steam vent passage and pile up; Do not need the clay in labor cleaning's steam vent, thereby accelerate operating speed.
As preferably, described flute of drill comprises left chip area and right chip area, and described drill bit steam vent passage is positioned on the inwall of left bank bits groove, and described drill edge is positioned at the bottom of right chip area, and described drill bit steam vent passage is skewed distribution.
As preferably, described left chip area and right chip area are integrated, and the top of described left chip area and right chip area extends to the anterior upper end sidewall of drill body.
As preferably, described drill bit steam vent passage is an arcuation.
Therefore, the anti-blocking structure of the chip removal pore of a kind of cut drill of the utility model, simple in structure, easy to use, improve the efficient of work.
