Abstract
The invention aims to provide a drill bit with a chip removal machine. The drill bit with the chip removal machine comprises a drill shank and an edge portion. The edge portion is mounted at an end of the drill shank and is axially provided with at least two parabolic cutting edges, and chip grooves are formed in positions among the adjacent cutting edges. The drill bit is characterized in that the cylindrical chip removal machine is detachably mounted at the head end of the drill shank, chip removal protrusions are arranged at the end, which is close to the direction of the edge portion, of the chip removal machine, the quantity of the chip removal protrusions is identical to that of the chip grooves, and the chip removal protrusions extend into the chip grooves. When the chip grooves of the drill bit are filled with accumulated chips in hole drilling procedures, the drill bit is taken out, the chip removal machine is separated from the head end of the drill shank and rotates along the rotation directions of the chip grooves, the chip removal protrusions of the chip removal machine advance along the chip grooves, accordingly, the chips accumulated in the chip grooves can be removed, the chip removal machine is ultimately mounted at the head end of the drill shank, and holes can be drilled again. The drill bit has the advantage that the chip removal efficiency can be improved.
Description
Technical field
The invention belongs to bit technique field, specially refer to a kind of drill bit that carries dross extractor.
Background technology
While utilizing drill bit to hole in soft material, the disintegrating slag that boring produces can inevitably stick in the chip area of drill bit, and cannot automatically discharge along with the rotation of drill bit.So just must drill bit be taken out stopping the work of boring, carry out could continuing to use after artificial scarfing cinder.And be not exclusively used in now the scarfing cinder utensil of drill bit, so clinkerer makes comparisons slowly, had a strong impact on the efficiency of holing.
Summary of the invention
The object of the invention is to propose a kind of drill bit that carries dross extractor, to improve the efficiency of scarfing cinder.
The drill bit that carries dross extractor of the present invention comprises drillstock and the blade that is arranged on drillstock end, and described blade is provided with at least two parabola shaped cutting edges vertically, between adjacent cutting edge, forms chip area; Key is that the head end of described drillstock is removably provided with dross extractor cylindraceous, and described dross extractor is provided with and the same number of scarfing cinder protuberance of described chip area near the end of blade direction, and described scarfing cinder protuberance stretches in described chip area.
In the process of boring, when the chip area inner product of drill bit expires chip, drill bit is taken out, and dross extractor is separated with the head end of drillstock, then along the direction of rotation of chip area, rotate dross extractor, the scarfing cinder protuberance of dross extractor is advanced along chip area, thereby the chip accumulating in chip area is walked clearly, the last head end of drillstock that again dross extractor is arranged on, continues boring.
Further, described dross extractor is installed on the head end of described drillstock by being clasped, with the dross extractor that is easy for installation and removal.
The drill bit that carries dross extractor of the present invention facilitates scarfing cinder, is specially adapted to hole in soft material, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation that carries the drill bit of dross extractor of the present invention.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in Figure 1, the drill bit that carries dross extractor of the present embodiment comprises drillstock 1 and the blade 2 that is arranged on drillstock 1 end, and described blade 2 is provided with at least two parabola shaped cutting edges vertically, forms chip area 3 between adjacent cutting edge; Key is that the head end of described drillstock 1 is removably provided with dross extractor 4 cylindraceous by being clasped, described dross extractor 4 is provided with and the same number of scarfing cinder protuberance 5 of described chip area 3 near the end of blade 2 directions, and described scarfing cinder protuberance 5 stretches in described chip area 3.
In the process of boring, when chip area 3 inner products of drill bit expire chip, drill bit is taken out, and dross extractor 4 is separated with the head end of drillstock 1, then along the direction of rotation of chip area 3, rotate dross extractor 4, the scarfing cinder protuberance 5 of dross extractor 4 is advanced along chip area 3, thereby the chip accumulating in chip area 3 is walked clearly, the last head end of drillstock 1 that again dross extractor 4 is arranged on, continues boring.
Claims (2)
1. carry a drill bit for dross extractor, comprise drillstock and the blade that is arranged on drillstock end, described blade is provided with at least two parabola shaped cutting edges vertically, between adjacent cutting edge, forms chip area; The head end that it is characterized in that described drillstock is removably provided with dross extractor cylindraceous, and described dross extractor is provided with and the same number of scarfing cinder protuberance of described chip area near the end of blade direction, and described scarfing cinder protuberance stretches in described chip area.
2. the drill bit that carries dross extractor according to claim 1, is characterized in that described dross extractor is installed on the head end of described drillstock by being clasped.
