Description
Technical field
The present invention relates to milling cutter technical field, particularly a kind of Double-edged milling cutter.
Background technology
Existing milling cutter versatility is comparatively strong, and when carrying out Milling Process to workpiece, chip removal ability is long, and service life is short, can not get cutting off owing to adding the scrap produced man-hour again, often cause trouble, even affect processing and the personal safety of workpiece, generally in chip process, larger heat can be produced, existing milling cutter is high due to point of a knife place cutting temperature, has little time cooling, easily makes cutter wear become and accelerates greatly, not only affect the machining accuracy of workpiece, also have influence on the service life of self.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, long service life, assembling firmly, can automatic chip breaking and the Double-edged milling cutter cooling cutter head.
Realize technical scheme of the present invention as follows:
A kind of Double-edged milling cutter, comprise handle of a knife and blade, described handle of a knife is provided with the principal screw groove between two blades, principal screw groove is provided with two, relative is arranged at blade both sides, the side of blade is provided with secondary helicla flute, secondary helicla flute two ends are connected with two principal screw grooves, described handle of a knife is provided with draw-in groove on the surface, draw-in groove is provided with Cooling Holes, lubrication channel is provided with in handle of a knife, one end of lubrication channel is connected with Cooling Holes, the other end is provided with branched bottom and is connected to blade, the chip breaking block be fixed on handle of a knife is provided with below draw-in groove, the end face of chip breaking block is set to arc shape.
Described two blades, for being oppositely arranged, connect into 180 ° of angles, and advantage adds complementation interference in man-hour, and scope of cutting is large.
The degree of depth of described draw-in groove one end is less than the other end, Cooling Holes is arranged on the darker one end of the degree of depth, advantage is convenient to chuck to fix milling cutter by being stuck in draw-in groove, so not only can milling cutter easy to setup, and in use milling cutter also can not produce skidding, because Cooling Holes is also located in draw-in groove, like this after chuck blocks draw-in groove, just Cooling Holes is enclosed, can prevent the cooling fluid in cooling bath or lubricating oil from spilling like this.
The circular arc end face of described chip breaking block is provided with multiple groove not of uniform size, and advantage to make scrap be forced to fracture, and groove not of uniform size improves chip breaking efficiency.
Described lubrication channel adopts variable-diameter structure, namely the diameter being positioned at the lubrication channel at cooling vent place is larger than the diameter being positioned at branched bottom place, advantage to make cooling fluid or lubricating oil at the uniform velocity down flow to cutter head, prevents flow velocity too fast and produce waste and process the phenomenon generation not completing and just use up.
Have employed above-mentioned scheme, principal screw groove can as chip area, in process, the scrap that workpiece produces is discharged along principal screw groove, scrap can pat the chip breaking block on handle of a knife, because short chip end face is arcuate structure, such scrap can be out of shape along its curved end track when encountering chip-breaking, so scrap can be made to bend, under groove effect on chip breaking block circular arc end face, the cutting edge of scrap to the edge of groove constantly applies tangential force, therefore scrap can constantly rupture, not only be conducive to chip removal, can also prevent it from having influence on work pieces process and ensure that personal safety, principal screw groove and secondary helicla flute are interconnected, the cutting pressure of blade can be reduced, the discharge of scrap is more conducive to when chip removal, scrap is effectively prevented seriously to adhere to cutting edge, cause generation built-up edge, reduce the wearing and tearing of cutter, improve machining accuracy and service life, by cooling fluid reserved in lubrication channel or lubricating fluid, milling cutter can be made in use to lower the temperature voluntarily or lubrication, effectively reduce the temperature produced in blade processing, the capacity of lubrication channel can either meet the demand adding amount in man-hour, waste can not be caused again, economical and practical, substantially prolongs the service life of Double-edged milling cutter.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of chip breaking block in the present invention;
In accompanying drawing, 1 is handle of a knife, and 2 is blade, and 3 is principal screw groove, and 4 is secondary helicla flute, and 5 is draw-in groove, and 6 is Cooling Holes, and 7 is chip breaking block, and 8 is lubrication channel, and 9 is groove, and 10 is branched bottom.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1 and Fig. 2, a kind of Double-edged milling cutter, comprise handle of a knife 1 and blade 2, described handle of a knife 1 is provided with the principal screw groove 3 between two blades 2, principal screw groove 3 is provided with two and relative is arranged at blade 2 both sides, the side of blade 2 is all provided with secondary helicla flute 4, secondary helicla flute 4 two ends are connected with two principal screw grooves 3, the surface of described handle of a knife 1 is provided with draw-in groove 5, draw-in groove 5 is provided with Cooling Holes 6, lubrication channel 8 is provided with in handle of a knife 1, one end of lubrication channel 8 is connected with Cooling Holes 6, the other end is provided with branched bottom 10 and is connected to blade 2, the chip breaking block 7 be fixed on handle of a knife 1 is provided with below draw-in groove 5, chip breaking block 7 is circulus, the lower surface of chip breaking block 7 is set to arc shape, the curved surfaces of chip breaking block 7 is provided with multiple groove 9 not of uniform size, advantage to make scrap be forced to fracture, groove not of uniform size in addition improves chip breaking efficiency.
Described two blades 2, for being oppositely arranged, connect into 180 ° of angles, and advantage adds complementation interference in man-hour, and scope of cutting is large.
The degree of depth of described draw-in groove 5 one end is less than the other end, Cooling Holes 6 is arranged on the darker one end of the degree of depth, advantage is convenient to chuck to fix milling cutter by being stuck in draw-in groove, so not only can milling cutter easy to setup, and in use milling cutter also can not produce skidding, because Cooling Holes is also located in draw-in groove, like this after chuck blocks draw-in groove, just Cooling Holes is enclosed, can prevent the cooling fluid in cooling bath or lubricating oil from spilling like this.
Described lubrication channel adopts variable-diameter structure, namely the diameter being positioned at the lubrication channel at cooling vent place is larger than the diameter being positioned at branched bottom place, advantage to make cooling fluid or lubricating oil at the uniform velocity down flow to cutter head, prevents flow velocity too fast and produce waste and process the phenomenon generation not completing and just use up.
