Abstract
The utility model is related to a kind of milling cutter for row milling finishing, including cutter hub and blade, cutter hub outer circumferential side is provided with spiral chip area, cutter hub lower section is installed by blade, blade is around cutter hub central shaft circumferential arrangement, open circles are provided with cutter hub bottom centre, open circles hollow out blade avris to the part of cutter hub central axis, cutting swarf enters in chip area through open circles discharges, open circles hollow out blade avris to the part of cutter hub central axis, blade is avoided to prevent cutting swarf from normally being discharged from chip area, will not occur to squeeze bits phenomenon, accelerate cutting speed, product is unlikely to deform, improve knife mark, increase cutter life, suitable for the row milling finishing without knife mark or bloom requirement to shear blade, it is particularly suitable for the relatively weak product structure in bottom surface.
Description
Technical field
The utility model is related to milling cutter, and in particular to a kind of milling cutter for row milling finishing.
Background technology
Plain milling, is called parallel milling, is the processing that a kind of milling cutter carries out milling along multigroup machining path being parallel to each other
Technique, the bottom centre position of traditional milling cutter is provided with cutting edge, cutting edge ensure milling cutter can cutting workpiece completely, but for
For during the actual row Milling Machining, the resistance that center cutter is subject to is very big, closer to center more without cutting force, can make
Into crowded bits and the knife that shakes, cause workpiece surface to produce knife mark, produce male and fomale(M＆F) plastic deformation, reduce crudy, it is impossible to meet real
Border production needs.
Utility model content
In order to be run into when solving the problems, such as milling cutter of the prior art for row Milling Machining, the utility model provides one kind
Reasonable in design, avoid squeezing bits, processing faster, for the milling cutter of row milling finishing, concrete technical scheme is as follows：
A kind of milling cutter for row milling finishing, including cutter hub and blade, cutter hub outer circumferential side are provided with spiral chip area, knife
Blade is installed in body lower section, and blade is provided with open circles around cutter hub central shaft circumferential arrangement at cutter hub bottom centre, open circles are hollowed out
To the part of cutter hub central axis, cutting swarf enters in chip area through open circles discharges blade avris.
Preferably, the hollow radius of circle is more than width of chip space and less than cutter hub radius.
Preferably, milling cutter is 4 blade milling cutters.
Preferably, milling cutter is 6 blade milling cutters.
Preferably, cutter hub radius is 8mm, and width of chip space is 1mm.
Preferably, cutter hub radius is 10mm, and width of chip space is 2mm.
The beneficial effects of the utility model：Open circles hollow out blade avris to the part of cutter hub central axis, it is to avoid blade
Prevent cutting swarf from normally being discharged from chip area, will not occur to squeeze bits phenomenon, accelerate cutting speed, product is unlikely to deform, and improves
Knife mark, increases cutter life, it is adaptable to the row milling finishing without knife mark or bloom requirement to shear blade, is particularly suitable for bottom surface
Relatively weak product structure.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is side view of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described further：
It is term " " center ", " on ", D score, "left", "right", " perpendicular, it is necessary to explanation in description of the present utility model
Directly ", the orientation or position relationship of the instruction such as " level ", " interior ", " outward " are, based on orientation shown in the drawings or position relationship, to be only
Described with simplified for the ease of description the utility model, must had rather than the position or element for indicating or implying meaning specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
As depicted in figs. 1 and 2, a kind of milling cutter for row milling finishing, including cutter hub and blade, cutter hub outer circumferential side are provided with
Blade is installed in spiral chip area, cutter hub lower section, and blade is provided with sky around cutter hub central shaft circumferential arrangement at cutter hub bottom centre
The heart is justified, and open circles hollow out blade avris to the part of cutter hub central axis, and cutting swarf enters chip removal in chip area through open circles.
Specifically, milling cutter is 4 blade milling cutters or 6 blade milling cutters, the hollow radius of circle R1 is more than width of chip space C2 and is less than
Cutter hub radius R, cutter hub radius R are 8mm, and width of chip space C2 is 1mm, or cutter hub radius is 10mm, and width of chip space is 2mm.
Milling cutter construction of the present utility model does not receive outside diameter d, length L, sword L1 long, spiral angle A, tread C1, sword number, butterfly
The specific influence of the cutter parameters such as angle, flute profile change, hollow radius of circle R1 need to only meet more than chip removal with the modification of design requirement
Well width C2 and less than the requirement of cutter hub radius R, is applicable to row milling finishing, it is to avoid squeeze the generation of bits phenomenon, accelerates
Cutting speed, meets produce reality needs.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations, for the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all regarded
To belong to protection domain of the present utility model.
