Abstract
The utility model discloses an inner-cooling cleaning milling cutter which comprises a cutter body, main cooling holes and sub cooling holes. The milling cutter is characterized in that the sub cooling holes are uniformly distributed around the main cooling holes; the sub cooling holes are distributed in an S shape; an inclined angle of 45 degrees is formed between the sub cooling holes and the milling cutter; the diameter of each main cooling hole is 7mm; the diameter of each sub cooling hole is 3.5mm; the number of the sub cooling holes is 8. Due to arrangement of the S-shaped sub cooling holes, when a gas passes through arcs in the holes, a buffer effect is achieved; due to the design of the inclined angle of 45 degrees, cuttings are not splashed when being cleaned, and the potential safety hazard is reduced. As a plurality of cooling holes are formed, the milling cutter can be uniformly cooled, the service life of the milling cutter can be prolonged, the material is saved, and the enterprise cost is lowered.
Description
Technical field
The utility model relates to a kind of milling cutter, and particularly the clean milling cutter of a kind of inner-cooled, belongs to metal-cutting machine tool technical field.
Background technology
Milling cutter, for Milling Process, have the rotary cutter of one or more cutters tooth.When work, each cutter tooth cuts the surplus of workpiece successively off and on.Milling cutter is mainly used in processing plane, step, groove, profiled surface and cut-out workpiece etc. on milling machine.Milling cutter is in the process of producing and use at present, and the scrap cutting easily covers on milling cutter, is unfavorable for that enterprise produces; And due to milling cutter Cutting Process at a high speed, in use very easily cause cutter hub excess Temperature, cause milling cutter to shorten service life, increased the cost of enterprise.Although the utility model patent that the patent No. is 2012201537087 provides a kind of inner-cooled milling cutter, its Cooling Holes is shaped as linear pattern, although in use can remove the smear metal of cutter rake face, but think that linear cooling duct can cause the smear metal being eliminated to splash, cause potential safety hazard.
Utility model content
The purpose of this utility model is in order to overcome above deficiency, provides a kind of inner-cooled to clean milling cutter
The purpose of this utility model realizes like this:
The clean milling cutter of a kind of inner-cooled of the utility model, comprises cutter hub, main Cooling Holes and point Cooling Holes, and wherein, described point of Cooling Holes is shaped as S type.
The clean milling cutter of above-mentioned a kind of inner-cooled, wherein, described point of Cooling Holes and milling cutter angle are 45 degree.
The clean milling cutter of above-mentioned a kind of inner-cooled, wherein, described main Cooling Holes diameter is 7mm.
The clean milling cutter of above-mentioned a kind of inner-cooled, wherein, described point of Cooling Holes diameter is 3.5mm.
The clean milling cutter of above-mentioned a kind of inner-cooled, wherein, described point of Cooling Holes quantity is 8.
Compared with prior art, the utlity model has following advantage:
1) dividing Cooling Holes is that S shape arranges, and when gas passes through arc in hole, has the effect of buffering, and 45 ° of angles designs, while making to remove smear metal, can not cause and splash, and reduces potential safety hazard.
2) setting of multiple Cooling Holes, makes milling cutter capable of being evenly cooling, extends milling cutter service life and saves material, reduces entreprise cost.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present utility model.
Fig. 2 is that the utility model is at cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, the clean milling cutter of a kind of inner-cooled of the utility model, comprises cutter hub 1, main Cooling Holes 2 and point Cooling Holes 3, it is characterized in that a described point Cooling Holes 3 is evenly distributed on main Cooling Holes 2 surroundings; Described point of Cooling Holes 3 is shaped as S type; Described point of Cooling Holes 3 is 45 degree with milling cutter angle; Described main Cooling Holes 2 diameters are 7mm; Described point of Cooling Holes 3 diameters are 3.5mm; Described point of Cooling Holes 3 quantity are 8.
The utility model beneficial effect is: divides the setting of Cooling Holes by S shape, when gas passes through arc in hole, has the effect of buffering, and 45 degree angles designs, while making to remove smear metal, can not cause and splash, reduce potential safety hazard.Be provided with multiple Cooling Holes, make milling cutter capable of being evenly cooling, extend milling cutter service life and save material, reduce entreprise cost.
Above embodiment is only for being further described the utility model; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
