Abstract
A kind of drill bit with arc chip pocket, the shank comprising the cutting tip being positioned at chisel edge, the spiral part with two spirality chip areas be connected with this cutting tip and be positioned at drill bit rear end, described spire office is provided with around this spiral part arc chip pocket of a week.The utility model is convenient to chip discharge in drilling process, ensures that in drilling process, drill bit feeding is steady, avoids, because chip removal does not freely cause drilling cuttings to squeeze wound boring, improving drilling converted products quality.The cooling effect of drill bit in process can be increased simultaneously, improve the service life of drill bit.
Description
Technical field
The utility model relates to drilling machining cutter, is specifically related to a kind of drill bit with arc chip pocket.
Background technology
, in metal drilling process, easily there is the problem affecting drilling converted products quality and cutter life because chip removal is not smooth in conventional spiral bit.The particularly drilling processing of aluminum products, squeeze wound seriously, and the problem affecting converted products quality is particularly outstanding because chip removal does not freely cause aluminium to consider to be worth doing.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of drill bit with arc chip pocket, and this drill bit is particularly suitable for the drilling processing of aluminum products, effectively can solve the problem affecting converted products quality and drilling life of bit because chip removal is not smooth.
The technical scheme realizing above-mentioned purpose is: a kind of drill bit with arc chip pocket, the shank comprising the cutting tip being positioned at chisel edge, the spiral part with two spirality chip areas be connected with this cutting tip and be positioned at drill bit rear end, described spire office is provided with around this spiral part arc chip pocket of a week.
Further, described arc chip pocket is arc groove.
Further, the front end slot of described arc chip pocket is along being connected with the rear end of described cutting tip, and the rear end slot of described arc chip pocket is along the rear end being positioned at described two spirality chip areas.
The beneficial effects of the utility model are:
1, due to the existence of arc chip pocket, this drill bit has more abundant chip space relative to the spiral bit of routine, can effectively reduce chip removal resistance, be convenient to drilling cuttings discharge in time, prevent chip area from blocking, ensure that in drilling process, drill bit feeding is steady, avoids because chip removal does not freely cause drilling cuttings to squeeze the generation injuring the problems such as sticky cutter, improve drilling converted products quality.
2, in drilling process, make emulsion enter in a large number from the arc chip pocket increased, and arrive rapidly at the bottom of hole, realize uninterrupted directly cooling, add cooling effect, reduce drill bit and add the heat produced man-hour, drill bit is cooled fully in High Rotation Speed process, extends cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the drill bit originally with arc chip pocket.
Detailed description of the invention
By reference to the accompanying drawings detailed description of the invention of the present utility model is described.
The drill bit originally with arc chip pocket comprises the cutting tip 1 being positioned at chisel edge, the alloy blade of cutting tip 1 for inlaying of accompanying drawing embodiment.The spiral part 2 with two spirality chip areas is engaged on after cutting tip 1.Columniform shank 3 is positioned at the rear end of drill bit.Be provided with around this spiral part arc chip pocket 4 of 2 one weeks at spiral part 2 place.The arc chip pocket 4 of accompanying drawing embodiment is arc groove.The front end slot of arc chip pocket 4 is along being connected with the rear end of cutting tip 1, and the rear end slot of arc chip pocket 4 is along the rear end being positioned at two spirality chip areas.
When the utility model is specifically implemented, the minimum diameter place of arc chip pocket 4 should be not less than 2/3 of the maximum effective cutting diameter of drill bit, to ensure the strength and stiffness of drill bit.
