Description

A kind of fluted drill
Technical field
The utility model belongs to process tool technical field, relates to a kind of fluted drill.
Background technology
Fluted drill be by the rotary cutting of its relative fixed axis with the instrument of drilling workpiece circular hole, be similar to fried dough twist because of its chip pocket curl and gain the name.Fluted drill can be clamped on manual, electronic Handheld drill instrument or drilling machine, milling machine, lathe and even machining center and use, and its drill bit material is generally high-speed tool steel or carbide alloy.Conventional fluted drill comprises at least one spiral flute, land and cylindrical cutter body, and wherein flute and land follow helical angle to the front edge of a knife.Conventional fluted drill, when drilling, chip is not easily discharged, and chip space during chip removal is little, and chip removal is not smooth, easy breaking.Because the gap between fluted drill and workpiece circular hole is less, cooling fluid not easily arrives apex point, lubrication weak effect, and the reconditioning difficulty of cutting edge is large, and affect chip breaking effect, maintenance cost is high, and working life is short, and the precision and stability of the product processed is low.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes that a kind of chip removal is effective, the fluted drill of good cooling results.
The purpose of this utility model realizes by following technical proposal:
This fluted drill, comprise drilling rod and the apex point being located at drilling rod front end, the both sides of described apex point have spiral respectively and are located at chip area on drilling rod, the corresponding setting of chip area described in two, it is characterized in that, the surface of the described drilling rod part between two chip areas is provided with chip pocket, a side of described chip area is the parabola shaped face one inwardly concaved, described parabola shaped face one is provided with cutting edge with the junction of chip pocket, the another side of described chip area is outwardly parabola shaped face two, described parabola shaped face two is connected with chip pocket, the surface of the described drilling rod part between two chip areas is provided with the groove covering chip pocket and cutting edge.
This groove can store a small amount of cooling fluid, if when adding that man-hour, external cooling fluid cannot enter, the cooling fluid being positioned at groove fully can cool apex point, and this groove can store the scrap that chip gets off, scrap can not be had an impact to the workpiece circular hole of processing, ensure the machining accuracy of workpiece employee.
In above-mentioned fluted drill, described groove is several and length direction along drilling rod extends, and some described grooves are uniformly distributed.
In above-mentioned fluted drill, the sidewall of described groove is formed scrapes bits sword for what scrape bits.
In above-mentioned fluted drill, described groove is groove, and its two ends are communicated with the chip area described in two respectively.After cooling fluid is entered by chip area, can enter in groove, better Cooling and Lubricator be carried out to fluted drill, effectively extend the service life of fluted drill.
Compared with prior art, this fluted drill has the following advantages:
Groove is provided with on the surface of drilling rod, the two ends of this groove are communicated with two chip areas respectively, groove can store a small amount of cooling fluid, if when adding that man-hour, external cooling fluid cannot enter, the cooling fluid being positioned at groove fully can cool apex point, and this groove can store the scrap that chip gets off, scrap can not be had an impact to the workpiece circular hole of processing, ensure the machining accuracy of workpiece employee.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment that the utility model provides.
In figure, 1, drilling rod; 2, apex point; 3, chip area; 31, parabola shaped face one; 32, parabola shaped face two; 4, chip pocket; 5, cutting edge; 6, groove; 61, bits sword is scraped.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Fluted drill as shown in Figure 1, comprises drilling rod 1 and is located at the apex point 2 of drilling rod 1 front end, and the both sides of apex point 2 have spiral respectively and are located at chip area 3, two corresponding settings of chip area 3 on drilling rod 1.As shown in Figure 1, the part of the surface of drilling rod 1 between two chip areas 3 is provided with chip pocket 4, a side of chip area 3 is the parabola shaped face 1 inwardly concaved, parabola shaped face 1 is provided with cutting edge 5 with the junction of chip pocket 4, the another side of chip area 3 is outwardly parabola shaped face 2 32, parabola shaped face 2 32 is connected with chip pocket 4, the surface of drilling rod 1 part between two chip areas 3 is provided with the groove 6 covering chip pocket 4 and cutting edge.Groove 6 in the present embodiment can store a small amount of cooling fluid, if when adding that man-hour, external cooling fluid cannot enter, the cooling fluid being positioned at groove 6 fully can cool apex point 2, and this groove 6 can store the scrap that chip gets off, scrap can not be had an impact to the workpiece circular hole of processing, ensure the machining accuracy of workpiece employee.
Concrete, as shown in Figure 1, groove 6 is several and length direction along drilling rod 1 extends, and some grooves 6 are uniformly distributed.As shown in Figure 1, the sidewall of groove 6 is formed and considers sword 61 to be worth doing for scraping scraping of bits.
In the present embodiment, groove 6 is groove, and its two ends are communicated with two chip areas 3 respectively.After cooling fluid is entered by chip area 3, can enter in groove 6, better Cooling and Lubricator be carried out to fluted drill, effectively extend the service life of fluted drill.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
