Fig. 3 is the structural representation of centering cone.
Embodiment
For make the present invention illustrate be more fully apparent from, the present invention is described in further details below in conjunction with the accompanying drawings.
Embodiment：
Referring to figs. 1 to Fig. 3, the present embodiment provides a kind of nonmetallic thin mat piece highly-efficient processing device of circle, including knife rest 1, centering
Cone 2 and cutter head 3, knife rest 1 include cutterhead 11 and are perpendicularly fixed at the handle of a knife 12 of the one end of cutterhead 11, opened up on the other end of cutterhead 11
There is cone groove 13, and cone groove 13 and handle of a knife 12 are coaxial, one end of centering cone 2 is arranged in cone groove 13, and the other end on the other side is
For the pyramidal structure of positioning, two cutter heads 3 are fixedly installed on the other end of the cutterhead 11, and two cutter heads 3 arrive cone groove
The distance at 13 centers is identical with the inside/outside diameter size to be processed of workpiece 4 to be added respectively, and the cutter head 3 is cutting-up cutter head, and cutter head 3 can
It is mounted on cutterhead 11 detachable, is specially：At least two cutter head fixing holes 14 are offered on the other end of cutterhead 11,
The cutter head 3 is fixed on cutter head fixing hole 14 by handle of a knife 5.
Theoretical foundation is:Positioning using nonmetal plate by centering cone 2, ensure that positioning precision, in process
Not offseting ensures that inside and outside circle size axiality is higher, and cutter head two pieces is one group, and one control excircle dimension, and one control inner circle chi
It is very little, the distance of cutter head is adjusted flexibly according to different inside and outside circle sizes, realizes the processing of products of different specifications, the Tool Design is real
Now without machining, material cost is saved, two cutter heads are processed to inside and outside circle, make to be processed and formed at one time product respectively simultaneously
It is possibly realized, endoporus clout intact unbroken can be used for the production of more small dimension product, realize overlaying processing, the material being applicable
Expect for sheet material, elastomeric material and nonmetallic materials.
Knife rest 1 be by handle of a knife 12 and cutterhead 11 be welded the center line of handle of a knife 12 and cutterhead 11 baseplane perpendicularity it is little
In 0.5mm, there is enough intensity, rigidity, form does not do excessive requirement, and the material of handle of a knife 12 is using 40Cr steel alloys through quenching
Fire+tempering, machining, which is made, behind hardness HRC48~55 ensures enough obdurabilities, the material of cutterhead 11 using 45 steel it is quenched+
It is tempered, machining, which is made, behind hardness HRC40~45 ensures enough obdurabilities.The material of handle of a knife 12 uses 40Cr steel alloys and knife
The material of disk 11 is mainly additionally contemplates that the weldability between two kinds of materials is good using 45 steel in addition to the demand of obdurability.
The material of centering cone 2 using Cr12MoV alloy tool steels it is quenched+tempering, system is machined behind hardness HRC55~63
Into cone angle is that 35 ° of centering are stable, is threadedly coupled with knife rest 1 conveniently replaced.
The material of cutter head 3 using Cr12MoV alloy tool steels it is quenched+tempering, hardness is machined descendant behind HRC55~63
Work sharpening is made.The bigger resistance to cutting of tool orthogonal rake is smaller in principle by tool orthogonal rake γ, more favourable to processing, but considers rubber material
The processing characteristics and machining state of material and nonmetallic materials, tool orthogonal rake γ make the arrow of the axial thrust load of cutting force using negative rake
Measure direction and point to 8- backing plates, tool orthogonal rake γ, which recommends -5 °~-8 °, prevents blank sheet material in the presence of cutting force to tool orientation
Warpage winding cutter influences to process, and cutter angle of wedge β recommends 35 °~55 °, and the reduction of cutter rake face is into a line, and change has cutting to add
Work is the cutting-up added without cutting.Chipless, dust produce safety and environmental protection, reduce the human injury to processor, and tool clearance α is former
Relief angle of then fixing a cutting tool cut more greatly with finished surface rub it is smaller, to process it is more favourable, but consider cutter intensity and radiating condition
Span should not be too big, recommends α：3 °~5 °, after the centripetal side in the side of cutter head 3 uses designed arc-shaped appearance equivalent to increase cutter side
Angle, reduce the friction between cutter and workpiece, reduce cutting heat, arc radius R spans should not be too small, particularly outside part
When footpath size is larger, value too little Yi makes cutting heat substantially increase with producing friction with finished surface, according to product inside and outside circle chi
Very little determination, cutter head 2 are threadedly coupled conveniently replaced with knife rest.
The material of backing plate 6 is made of materials softer, that skin-friction coefficient is larger such as plank, bakelite plate, PVC versions,
Surfacing is asked, is advantageous to clout while no focal adhesion that comes off during inside and outside circle processing.
Specific processing method is as follows：
Knife rest 1 is clamped on bench drill, requires handle of a knife 12 with bench drill main shaft axiality in 0.05mm in installation process
Within, the distance of centering cone 2 is arrived according to the good cutter head 3 of product inside and outside circle size adjusting, the point of a knife of two cutter heads 3 is in the same plane
And less than 1~2mm of cone of centering cone 2, guarantee is first felt relieved is cut afterwards, and blank sheet material is placed on backing plate 6, and adjustment lathe turns
Speed, ensure that the cutter head linear velocity of processing excircles is less than or equal to 15m/s, starting machine tool control handle makes cutter descending without trial cut pair
Knife, directly once complete processing.
