Abstract
An improved tri-plane drill comprises a drill bit. The drill bit comprises a transverse edge and an outer edge. The transverse edge of the drill bit comprises a first flank knife surface and a second flank knife surface which are provided with a front knife surface respectively. The outer edge is provided with a chip discharge groove. The lower portion of the drill bit is provided with a drill shank and the lower portion of the drill shank is connected to a base. The connection portion of the drill shank with the base is provided with a buffer. By means of the above improvement, the improved tri-plane drill has the advantages of being capable of improving the abrasion resistance of the drill bit, prolonging the service life of the drill bit, achieving less proneness to breakage and reducing the hindrance to machining due to chips.
Description
Technical field
The present invention relates to a kind of instrument of process wood, particularly relate to a kind of three flat face bit of improvement.
Background technology
In the processing of timber, often need to use electric drill, and the core of electric drill is drill bit, therefore the quality of drill bit is related to the success or failure of processing, it is higher to there is axial force in drill bit in the market, centering performance is not good, wear no resistance and drill bit large due to impulsive force, easily collapse the easy block vision of chip that folding and process wood produce and stick on clothes and bring inconvenience to processing.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, provide a kind of axial force lower, centering excellent performance, can cushioned drill bit impact and three flat face bit of improvement of machining chips interference processing can be stopped.
Technical scheme provided by the invention is: a kind of three flat face bit of improvement, comprise drill bit, described drill bit comprises chisel edge and outside, the chisel edge of described drill bit comprises major first flank and the second rear knife face, after described major first flank and second, knife face has rake face, be provided with chip area between described outside, described drill bit bottom is provided with drillstock, described drillstock bottom connects base, and described drillstock and base junction are provided with the impulsive force cushioning described drill bit.
Further improvement of the present invention is: described drillstock bottom connects base, and described drillstock and base junction are provided with buffer.
Further improvement of the present invention is: described pan frontward end is provided with hyaline smooth discoid baffle plate.
Further improvement of the present invention is also: described bit exterior is set up defences corrosion layer.
The invention has the beneficial effects as follows: 1. strengthen drill bit intensity.2. not easily collapse folding.3. reduce the obstruction of chip to processing.

Fig. 1 is structural representation of the present invention
1-drill bit, 2-chisel edge, 3-outside, 4-major first flank, knife face after 5-the second, 6-rake face, 7-chip area, 8-drillstock, 9-base, 10-buffer, 11-discoid baffle plate.
Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, not forming protection scope of the present invention and limiting.
The present embodiment is as shown in Figure 1: a kind of three flat face bit of improvement, comprise drill bit 1, described drill bit 1 comprises chisel edge 2 and outside 3, the chisel edge 2 of described drill bit 1 comprises major first flank 4 and the second rear knife face 5, described major first flank 4 and the second rear knife face 5 have rake face 6, and be provided with chip area 7 between described outside 3, described drill bit 1 bottom is provided with drillstock 8, described drillstock 8 bottom connects base 9, and described drillstock 8 and base 9 junction are provided with the buffer 10 of the impulsive force cushioning described drill bit 1.
The present invention is when specifically using, chisel edge 2 due to described drill bit 1 comprises major first flank 4 and the second rear knife face 5, described major first flank 4 and the second rear knife face 5 have rake face 6, such design can reduce axial force, improve qualitative performance, improve drill bit durability, described drillstock 8 and base 9 junction are provided with buffer 10, because the impulsive force of drill bit is large, long-time use drill bit 1 can collapse folding, just need to change to repair, improve cost, because drill bit 1 is not only protected in the impact arranging buffer 10 available buffer drill bit 1, increase the service life, and can alleviate because drill bit 1 impacts the vibrations caused to hand, play the object of protection user, and in timber processing, chip can because the impact of drill bit 1 be dispersed everywhere, this will have influence on the sight line of user, and chip also can fall user with it thus to timber processing bring inconvenience, described base 9 front end is provided with hyaline smooth discoid baffle plate 11, so just can play and stop chip and obstruct the view and stop that chip is not stained with effect with it, and discoid baffle plate 11 adopts light transparent plastics material can not form impact to the sight line of user, the weight that also can not increase the weight of drill bit 1 causes burden to user, described drill bit 1 outside is provided with corrosion-resistant coating to protect drill bit 1 not by external corrosion, increase the service life.
