Abstract
The utility model relates to the technical field of machining equipment, particularly to an anti-blockage drill, which includes a cutter body and a blade, wherein the cutter body is a cylinder; a chip groove surrounds the lower part of the cutter body; the blade is positioned at the bottom end of the cutter body; separation pits are arranged on the cutter body. According to the utility model, the separation pits are uniformly arranged inside the chip groove, air can be stored in the separation pits, so that the separation pits can effectively separate chips from the wall of the chip groove and prevent the vacuum fit of chips and the wall of the chip groove, adsorption and blockage as well as high temperature heating can be avoided, as a result, the performance of the drill and the drilling efficiency can be greatly improved.
Description
Technical field
The utility model relates to the machining equipment technical field, especially a kind of anti-blocking 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, the chip area at rear portion is responsible for outside the chip tap, in the chip removal process, due to the cell wall smoother of chip area, fit closely with pulverous chip, be very easy to hold, make chip be difficult to discharge, cause obstruction, cause the high temperature heating, affect the performance of drill bit and the efficient of boring.
The utility model content
Easily block up in order to overcome existing drill bit chip removal, affect the deficiency of drilling efficiency, the utility model provides a kind of anti-blocking drill bit.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-blocking 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 isolation hole.
According to another embodiment of the present utility model, comprise that further isolating the hole is evenly distributed in chip area.
The beneficial effects of the utility model are, the isolation hole evenly is set in chip area, and isolation storing air in the hole, can effectively isolate the vacuum abutted of chip and chip area cell wall, prevent the absorption obstruction, avoid the high temperature heating, 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. isolation hole, 5. chip area.
The specific embodiment
Be structural representation of the present utility model as Fig. 1, a kind of anti-blocking 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 isolation hole 3.Isolation hole 3 is evenly distributed in chip area 5.
Isolate hole 3 interior evenly setting of chip area 5, isolation is cheated in 3 and being stored air, can effectively isolate the vacuum abutted of chip and chip area 5 cell walls, prevents the absorption obstruction, avoids the high temperature heating, thereby greatly improves the performance of drill bit and the efficient of boring.
