Abstract
The utility model relates to the technical field of machining equipment, in particular to a drill bit with a high chip removal effect. The drill bit comprises a cutter body and cutting edges, wherein the cutter body is a cylinder; a chip groove surrounds the lower part of the cutter body; the cutting edges are located at the bottom end of the cutter body; inverted tooth stands are arranged on the cutter body; the inverted tooth stands are uniformly arranged in the chip grooves and are perpendicular to the chip grooves to form a consecutive stair; during chip removal, a large chip flow is transversely broken by vibration and cut off so as to prevent chips from forming a large pile; chips are forcedly squeezed out in a waved manner so as to improve the chip removal speed; therefore, the performance and drilling efficiency of the drill bit are greatly improved.
Description
Technical field
The utility model relates to the machining equipment technical field, especially a kind of forced-ventilated drill bit.
Background technology
In machining, hole processing is the processing technology of commonly using, industry adopts electric drill to carry out hole processing usually, existing drill bit is all the integral type cylinder, be provided with cover blade and a chip area, the blade of front end is responsible for cutting, and the chip area at rear portion is responsible for outside the chip tap, in the chip removal process, due to chip area not only wide but also light, fit closely with pulverous chip, be very easy to hold, the chip of piling up on cross section is also many, flow velocity is slower, cause obstruction, cause the high temperature heating, affect the performance of drill bit and the efficient of boring.
The utility model content
Existing drill bit chip removal is slow easily stops up in order to overcome, and affects the deficiency of drilling efficiency, and the utility model provides a kind of forced-ventilated drill bit.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of forced-ventilated drill bit, comprise cutter hub and blade, and cutter hub is cylinder, and chip area is around the cutter hub bottom, and blade is positioned at the cutter hub bottom, and cutter hub is provided with the pawl platform.
According to another embodiment of the present utility model, comprise that further the pawl platform is evenly distributed in chip area, joins end to end into stepped.
According to another embodiment of the present utility model, comprise that further the pawl platform is vertical with chip area.
The beneficial effects of the utility model are, the pawl platform evenly is set in chip area, the pawl platform is vertical with chip area, be arranged in a coherent ladder, during chip removal, large strand of chip stream transverse-vibration can be broken and cut apart, avoid being piled into bulk, and contoured chip is outwards pushed away by force, improve chip removal speed, thereby greatly improve the performance of drill bit and the efficient of boring.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cutter hubs in figure, 2. blade, 3. pawl platform, 5. chip area.
The specific embodiment
Be structural representation of the present utility model as Fig. 1, a kind of forced-ventilated drill bit comprises cutter hub 1 and blade 2, and cutter hub 1 is cylinder, and chip area 5 is around cutter hub 1 bottom, and blade 2 is positioned at cutter hub 1 bottom, and cutter hub 1 is provided with pawl platform 3.Pawl platform 3 is evenly distributed in chip area 5, joins end to end into stepped.Pawl platform 3 is vertical with chip area 5.
At the interior pawl platform 3 that evenly arranges of chip area 5, pawl platform 3 is vertical with chip area 5, be arranged in a coherent ladder, during chip removal, can be avoided being piled into bulk a large burst of chip stream transverse-vibration disconnected cutting apart, and contoured chip outwards be pushed away by force, improve chip removal speed, thereby greatly improve the performance of drill bit and the efficient of boring.
