Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1 to Fig. 3, below the embodiment of process tool of the present invention is set forth.
The process tool of the present embodiment, is suitable for the art design slot of mobile phone metal outer frame, certainly also can carry out high light processing to the slotted eye of other metalwork, or carry out high light processing to metal product.Particularly, this process tool 100 comprises knife bar 10 and cutter head 20, is described further below to each parts of this process tool 100:
Knife bar 10 is arrange with installing for cutter head 20, and simultaneously it can clamped by processed main shaft; This knife bar 10 is post shapes, and its lateral cross section is T-shaped;
The second end 22 that cutter head 20 comprises first end 21 and is oppositely arranged with first end 21, the first end 21 of cutter head 20 is connected with knife bar 10, second end 22 of cutter head 20 is provided with in order to the cutting edge 23 to workpiece machining, particularly, cutting edge 23 comprises the first cutting edge 231 and the second cutting edge 232, second cutting edge 232 is located at the first cutting edge 231 side and crossingly with the first cutting edge 231 is arranged, and the first cutting edge 231 is arcuate structure, and the second cutting edge 232 is planar structure.
Cutter head 20 due to the process tool 100 of the present embodiment has the first cutting edge 231 and the second cutting edge 232, and this first cutting edge 231 is arcuate structure, second cutting edge 232 is planar structure, thus, when the art design slot of processing mobile phone metal outer frame, can by the arcuate structure of the first cutting edge 231, process the smooth and art design slot of no concave-convex sense of surface, wiring; Meanwhile, also by the planar structure of the second cutting edge 232, while the height dimension ensureing art design slot, the height component of art design slot can also be made to reach highlighted, high-precision effect.
Refer to Fig. 2, and composition graphs 1, first cutting edge 231 of the present embodiment has and the initial contact point M of workpiece initial contact and the last contact point N that finally contacts with workpiece, distance between initial contact point M and last contact point N is 0.05-0.15mm, the height being equivalent to the arcuate structure of the first cutting edge 231 is 0.05-0.15mm, and this is of a size of and draws through test of many times, except ensureing that the cutting edge 23 of cutter head 20 has ideal point of a knife, Gao Guang can be processed smoothly, high-precision art design slot, also the oversize of the cutter head 20 arranged be can avoid and the reduction of its hardness and consumptive material honest material caused.
In addition, the first cutting edge 231 is obliquely installed relative to the axial direction line Z of knife bar 10, to make the point of a knife of cutting edge 23 have comparatively outstanding distance, is beneficial to the contact with workpiece.
Side by side, in order to make process tool 100 process the art design slot of mobile phone metal outer frame from top to bottom, this first cutting edge 231 favours the axial direction line Z of knife bar 10 from top to bottom inwardly.
Further, the smoothness in order to process perpendicularity between art design slot and mobile phone metal outer frame and wiring preferably, the second cutting edge 232 intersects vertically with the axial direction line of knife bar 10, with the height wall making the second cutting edge 232 flatly fit in art design slot.
Refer to Fig. 3, and composition graphs 1 and Fig. 2, the knife bar 10 of the present embodiment is provided with the storage tank 11 that the first end 21 of cutter head 20 can be supplied accommodating, and the first end 21 of cutter head 20 is placed in storage tank 11, by the socket connection of this storage tank 11, together with making cutter head 20 and knife bar 10 group connect preferably.Side by side, in order to make this cutter head 20 firmly be connected on knife bar 10, first end and the knife bar 10 of cutter head 20 are welded to connect; Certainly, also can adopt screw connection manner, firmly be connected with knife bar 10 to make the first end of cutter head 20.
Cutter head 20 is provided with first inclined plane 24 that can make it easy to be located on storage tank 11, and the openend of storage tank 11 is provided with the second inclined plane 12, first inclined plane 24 and the second inclined plane 12 is equipped with.Wherein, when the first end 21 of cutter head 20 is located at storage tank 11, the first end 21 of cutter head 20 can be made to enter in this storage tank 11 from the side of storage tank 11, now, can by being equipped with between the first inclined plane 24, second inclined plane 12, the first end 21 of effective dispersion cutter head 20 enters the dynamics of storage tank 11, and reduces resistance, greatly facilitates the installation of installation personnel to operate.
Preferably, in order to ensure the crudy of cutter head 20 pairs of mobile phone metal outer frame, the material of the cutter head 20 of the present embodiment is high-speed steel, carbide alloy, pottery, cubic boron nitride, diamond or diamond.
Wherein, high-speed steel, it is used in the workpiece material of workhardness lower than HRC30; Side by side, it is better flexible, and manufacturability is better, can make the cutter of more complicated.That hardness is lower as its shortcoming, rigid difference.
Carbide alloy, the workpiece material of its applicable below workhardness HRC45, and also its face coat aft-loaded airfoil hardness reaches about HRC55's.
Ceramic material, it is mainly used in cast iron materials processing, rigid good.But its manufacturability is poor, fragility is comparatively large, easily collapses.
Cubic boron nitride material, it can be used for the processing of cast iron, magnesium iron, hardened steel, heat-resisting allay material, and hardness is only second to diamond.But, its manufacturability extreme difference.
Diamond and diamond, its hardness is the highest, is mainly used in the high speed of aluminium alloy, Precision Machining, also can be used for the processing of carbide alloy, graphite, timber etc.But, its manufacturability extreme difference, extremely crisp, non-refractory.
As for knife bar 10, its material can be chosen for No. 45 steel, both can ensure that it reaches required instructions for use, can reduce production cost again.
The foregoing is only preferred embodiment of the present invention, its structure is not limited to the above-mentioned shape enumerated, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
