Description
Technical field
The utility model relates to a kind of auto parts and components tool, relate in particular to a kind ofly can hole simultaneously, the compound tool of ream face and chamfer machining, belong to the machine tools field of auto parts and components.
Background technology
At auto parts and components manufacture field, while processing comparatively complicated workpiece for a long time, conventionally adopt traditional substep processing mode, i.e. boring, ream face and chamfering substep carry out, this kind of processing mode add man-hour number of cutters used and manufacturing procedure many, not only increase company's tool management cost, in addition production is long man-hour, increase production cost, be unfavorable for improving the market competitiveness, and multiple be not that matching used cutter uses together, influencing each other may cause machine-shaping time.For above-mentioned phenomenon, also have at present and adopt compound tool to carry out auto parts and components processing, but current existing compound tool is because the content of processing is more simultaneously, processing environment complexity, so the life-span extreme difference of cutter, cutter life is 6000 left and right conventionally.Therefore how to improve the service life of compound tool, become a great problem in current compound tool research and development field.
Utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of compound tool, and this cutter is applicable to boring, ream face and the chamfer machining of auto parts and components, and the high and long service life of practicality, on average can reach 24000 left and right.
The utility model in order to solve the problems of the technologies described above adopted technical scheme is:
A kind of compound tool, comprise knife bar, the threaded one end of described knife bar is connected with a drill bit, and the connection that is positioned at knife bar and drill bit on knife bar is installed with a blade, the axial rake of described drill bit is 9.0～9.5 °, the helical angle of described drill bit is 16～18 °, and the axial rake of described blade is 8.5～9.0 °, and blade axial slices is 0.002～0.006mm near the distance of this end face circumferential edge of central spot tangent distance of the end face of drill bit one end.
Its further technical scheme is:
The axial rake of described drill bit is 9.2 °, and the helical angle of described drill bit is 17 °, and the axial rake of described blade is 8.7 °.
Described blade axial slices is 0.004mm near the distance of this end face circumferential edge of central spot tangent distance of the end face of drill bit one end.
Described blade is anchored on one end of knife bar by lock screw.
Described drill bit is contrary with the hand of spiral of drill bit self with the hand of spiral of knife bar threaded connection place.
Described blade is PCD blade.
Useful technique effect of the present utility model is: this compound tool is applicable to the boring of auto parts and components, ream face and chamfer machining, chip breaking chip removal ability is high, can reduce cutter and be subject to processing the drag that elastic properties of materials plastic deformation produces, reduce the frictional force of smear metal to the face of registering, farthest reduce the cutting force that cutter is subject to, make cutter at processing content very under complex environment, may have higher cutter life, the average life span of this compound tool can reach 24000 left and right, and this cutter fast changeable, reduce work hours, significantly reduce production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In conjunction with Fig. 1, the utility model is described in further detail.
A kind of compound tool, comprise knife bar 1, the threaded one end of described knife bar 1 is connected with a drill bit 2, and on knife bar 1, be positioned at knife bar 1 and be installed with a blade 3 with the connection of drill bit 2, the axial rake of described drill bit 2 is 9.0～9.5 °, the helical angle of described drill bit is 16～18 °, the axial rake of described blade 3 is 8.5～9.0 °, and blade 3 axial slices are 0.002～0.006mm near the distance of this end face circumferential edge of central spot tangent distance of the end face of drill bit one end, be can regard a flat-top taper as in the blade situation of amplifying again near the end face of drill bit one end, the height H of this taper is 0.002～0.006mm, its optimum height is 0.004mm.
The wherein restriction of drill bit axial rake and helical angle angle, is the elasticity of rapidoprint and the drag of plastic deformation being subject in order to reduce this compound tool, is also in order to reduce the frictional force of smear metal to rake face.Blade 3 is generally selected PCD blade, the material selection of this blade and axial rake and other designs are too high in order to reduce when cutting local heat in metal cutting of causing of speed inequality, very easily producing long-pending impact of cutting knurl, is the shake cutter phenomenon of bringing in order to reduce unbalance stress in addition.
The axial rake optimum of described drill bit 2 is 9.2 °, and the helical angle optimum of described drill bit is 17 °, and the axial rake optimum of described blade 3 is 8.7 °.Described blade 3 axial slices are 0.004mm near the distance optimum of this end face circumferential edge of central spot tangent distance of the end face of drill bit one end.
Described blade 3 is anchored on one end of knife bar 1 by lock screw 4.In addition the hand of spiral of the hand of spiral of drill bit 2 and knife bar 1 threaded connection place and drill bit 2 self is contrary.Because the hand of spiral of drill bit self is consistent with cutting direction, when junction hand of spiral and bit cutting opposite direction, this compound tool has auto-lock function, can prevent loosening in working angles of compound tool.
