Description
Technical Field
The utility model relates to a technical field of drill bit, in particular to drill bit convenient to chip removal.
Background
The drill bit is various in types, wherein the drill bit is one type, when the drill bit is used for punching wood, a large amount of scraps can be generated, the problem that the drill bit is clamped can be caused if the scraps cannot be timely removed, and the heat dissipation performance of the drill bit can be reduced due to a large amount of sawdust of the drill bit.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a journal bit convenient to chip removal is provided for solve among the prior art that describes among the background art the problem that the saw-dust is not convenient for get rid of, the heat dissipation is weak when punching.
In order to achieve the above object, the present invention provides the following technical solutions: the utility model provides a journal drill head convenient to chip removal, includes the drillstock, the drillstock is connected with the cylinder, the spiral winding has the brill body on the cylinder, the one end of boring the body and keeping away from the drillstock is provided with the cutting part, form spiral chip removal passageway between the brill body and the cylinder, the position of the chip removal passageway that corresponds on the outer periphery wall of cylinder is provided with spiral chip groove, the one end that the drillstock was kept away from to the cylinder is provided with the column toe, be provided with the air vent of two vertical cylinders that run through on the brill body.
Preferably: the two vent holes are respectively positioned at two sides of the column body.
Preferably: the column tip is conical.
Preferably: the outer arc surface of the column tip is provided with spiral threads.
Preferably: the column body, the column tip, the drill body and the blade part are integrated.
The beneficial effect of adopting above technical scheme is:
this application is through setting up the chip groove on the cylinder, the effectual chip removal ability that increases the chip removal passageway has increased the volume of chip removal to still can improve the radiating efficiency who bores the body through setting up two air vents on boring the body, also can play certain chip removal can.
Drawings
Fig. 1 is a front view of the drill bit for supporting bits to remove chips.
Fig. 2 is a schematic structural view of the auger bit convenient for chip removal of the present invention.
Wherein: the drill comprises a drill shank 10, a drill body 20, a column body 30, a chip removal channel 40, a chip removal groove 50, a vent hole 60, a column tip 70, a thread 71 and a blade part 80.
Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Embodiment, like [ fig. 1-2 ], in this embodiment, a drill bit convenient to chip removal, including the drill shank 10, the drill shank 10 is connected with the cylinder 30, spiral winding has the drill body 20 on the cylinder 30, the one end that the drill body 20 kept away from the drill shank 10 is provided with cutting part 80, form spiral chip removal channel 40 between the drill body 20 and the cylinder 30, the position of the chip removal channel 40 that corresponds on the outer circumferential wall of cylinder 30 is provided with spiral chip groove 50, the one end that the drill shank 10 was kept away from to the cylinder 30 is provided with the column toe 70, be provided with two vertical air vents 60 that run through the cylinder 30 on the drill body 20.
Preferably: two of the ventilation holes 60 are respectively located at both sides of the cylinder 30.
Preferably: the toe 70 is conical.
Preferably: the outer arc of the toe 70 is provided with a helical thread 71.
Preferably: the column body 30, the column tip 70, the drill body 20 and the blade 80 are integrated.
The specific implementation manner of this embodiment:
this application is when using, can improve the connection performance with the article of being processed through screw 71 on the toe that sets up and the toe 70 for the workman need not exert great thrust when beginning drilling, and when drilling, the saw-dust of production will be discharged through chip removal channel 40, can increase chip removal volume of chip removal channel 40 through the chip removal groove 50 that sets up, and the high temperature that produces can increase the radiating efficiency through air vent 60 when the chip removal.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
