Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1 to Fig. 3 is referred to, the embodiment to the process tool of the present invention is illustrated below.
The process tool of the present embodiment, certainly also can be to the grooves of other metalworks suitable for the art design slot of mobile phone metal outer frame
Hole carries out bloom processing, or carries out bloom processing to metal product.Specifically, the process tool 100 includes knife bar 10 and knife
First 20, each part of the process tool 100 is described further below：
Knife bar 10 is with for the installation settings of cutter head 20, while it can be processed clamped by main shaft；The knife bar 10 is cylindricality
Shape, its lateral cross section is T-shaped；
Cutter head 20 includes first end 21 and the second end 22 being oppositely arranged with first end 21, the first end 21 and knife of cutter head 20
Bar 10 is connected, and the second end 22 of cutter head 20 is provided with to the cutting edge 23 to workpiece machining, and specifically, cutting edge 23 includes
First cutting edge 231 and the second cutting edge 232, the second cutting edge 232 located at the side of the first cutting edge 231 and with the first cutting edge
231 intersecting settings, the first cutting edge 231 is arcuate structure, and the second cutting edge 232 is planar structure.
Because the cutter head 20 of the process tool 100 of the present embodiment has the first cutting edge 231 and the second cutting edge 232, and
First cutting edge 231 is arcuate structure, and the second cutting edge 232 is planar structure, thus, in U.S. of processing mobile phone metal outer frame
During work groove, can by the first cutting edge 231 arcuate structure, process that surface, wiring be smooth and art design slot of no concave-convex sense；
Meanwhile, also by the planar structure of the second cutting edge 232, while the height dimension of art design slot is ensured, moreover it is possible to make art designing
The height component of groove reaches highlighted, high-precision effect.
Referring to Fig. 2, and combine Fig. 1, first cutting edge 231 of the present embodiment has initial to be connect with what workpiece was initially contacted
The distance between contact M and the last contact point N finally contacted with workpiece, initial contact point M and last contact point N are 0.05-
0.15mm, the height equivalent to the arcuate structure of the first cutting edge 231 is 0.05-0.15mm, and the size of by repeatedly examination
Test and draw, except ensureing that the cutting edge 23 of cutter head 20 has ideal point of a knife, can smoothly process bloom, high-precision
Art design slot, can also avoid the oversized of the cutter head 20 set and cause its hardness to reduce and consumptive material honest material.
In addition, the first cutting edge 231 is obliquely installed relative to the axial direction line Z of knife bar 10, so that the knife of cutting edge 23
Point has more prominent distance, in favor of the contact with workpiece.
Simultaneously, in order that can be processed from top to bottom to the art design slot of mobile phone metal outer frame to process tool 100,
First cutting edge 231 favours the axial direction line Z of knife bar 10 inwardly from top to bottom.
Further, in order to preferably process the smooth of perpendicularity between art design slot and mobile phone metal outer frame and wiring
Degree, the axial direction line of the second cutting edge 232 and knife bar 10 intersects vertically, so that the second cutting edge 232 flatly fits in U.S.
The height wall of work groove.
Referring to Fig. 3, and combine Fig. 1 and Fig. 2, the knife bar 10 of the present embodiment, which is provided with, is available for the first end 21 of cutter head 20 to house
Storage tank 11, the first end 21 of cutter head 20 is placed in storage tank 11, by the socket connection of the storage tank 11, so that cutter head 20
Together with preferably group connects with knife bar 10.Simultaneously, in order that being us shown firmly attached to the cutter head 20 on knife bar 10, the of cutter head 20
One end is welded to connect with knife bar 10；Certainly, screw connection manner can be also used, so that the first end of cutter head 20 and the firm company of knife bar 10
Connect.
Cutter head 20 is provided with the first inclined plane 24 that can make it easy on storage tank 11, the openend of storage tank 11
Provided with the second inclined plane 12, the first inclined plane 24 is equipped with the second inclined plane 12.Wherein, by the first end 21 of cutter head 20
During located at storage tank 11, the first end 21 of cutter head 20 can be made to enter from the side of storage tank 11 in the storage tank 11, now, can be borrowed
Being equipped between the first inclined plane 24, the second inclined plane 12, the first end 21 of effectively scattered cutter head 20 enters storage tank
11 dynamics, and reduce resistance, significantly facilitate the installation operation of installation personnel.
It is preferred that in order to ensure crudy of the cutter head 20 to mobile phone metal outer frame, the material of the cutter head 20 of the present embodiment
For high-speed steel, hard alloy, ceramics, cubic boron nitride, diamond or diamond.
Wherein, high-speed steel, it is used in the workpiece material that workhardness is less than HRC30；Simultaneously, it is flexible preferably, work
Skill preferably, can make more complicated cutter.Have the disadvantage that hardness is relatively low as it, hardness is poor.
Hard alloy, it is adapted to below workhardness HRC45 workpiece material, and its face coat post-processing hardness reaches
To HRC55's or so.
Ceramic material, it is mainly used in cast iron materials processing, and hardness is good.But, its manufacturability is poor, and fragility is larger,
Easily collapse.
Cubic boron nitride material, it can be used for cast iron, magnesium iron, hardened steel, the processing of heat-resisting alloy material, and hardness is only second to
Diamond.But, its manufacturability extreme difference.
Diamond and diamond, its hardness highest are mainly used in high speed, the Precision Machining of aluminium alloy, it can also be used to
The processing of hard alloy, graphite, timber etc..But, its manufacturability extreme difference, extremely brittle, non-refractory.
As for knife bar 10, its material can be chosen for No. 45 steel, can both ensure that it reaches required use requirement, and energy
Reduce production cost.
The foregoing is only preferred embodiments of the present invention, its structure is not limited to the above-mentioned shape enumerated, it is all
Any modifications, equivalent substitutions and improvements made within the spirit and principles in the present invention etc., should be included in the protection of the present invention
Within the scope of.
