Abstract
The invention provides a special cutter for turning an ultra-thin gasket. The special cutter comprises a blade, wherein the blade comprises a cutting edge, a front end surface of the blade and an upper surface of the blade; the front end surface of the blade is an inclined plane; a gap is formed in one end, close to the cutting edge, of the front end surface of the blade; and a groove is formed in one end, close to the cutting edge, of the upper surface of the blade. The inclined front end surface of the cutter is adopted by the special cutter for turning the ultra-thin gasket, and when a thin gasket is cut off, the knife point on the front surface of the cutter cuts off the edge of the gasket, and the cut gasket is free of a flash or a curled edge, and is flat and uniform in thickness; the gap is formed in the front of the cutting edge and plays a centering role in the cutting process, and the influence on the cutter of cutting thrust is eliminated. The groove is formed in the upper surface of the cutter, and the angle of the knife point is further reduced, so that the knife point is relatively sharp; drainage is facilitated; and accumulation of raw material debris is eliminated.
Description
Technical field
The present invention relates to machining cutting knife technical field, particularly relate to a kind of turning and process ultrathin padSpecial cutter.
Background technology
Often need a kind of extra-thin pad at machinery industry, general thickness is 0.20mm～0.40mm, this classPad generally adopts plastics or the machine-shaping on lathe of tetrafluoro bar, processes ultra-thin pad with normal cutting knifeThere is edge flange in Shi Changchang, overall fold, and the phenomenons such as became uneven, percent defective is high, normally scales offPart also needs artificial reparation.
Summary of the invention
Technical problem to be solved by this invention is: process ultra-thin pad in order to overcome normal cutting knife in prior artWhen sheet, usually there is edge flange, overall fold, became uneven, the deficiency that percent defective is high, the invention providesUltrathin pad special cutter is processed in a kind of turning.
The present invention solves the technical scheme that its technical problem will adopt: ultrathin pad is processed in a kind of turningSpecial cutter, comprises blade, and described blade comprises blade and blade front end face, and described blade is positioned at described cutterThe upper end of sheet front end face, is characterized in that: described blade front end face is an inclined-plane, the inclination side on described inclined-planeTo tilting to the other end for the one end that is provided with blade from blade front end face.
The parallel surface of cutting knife front end face is worn into a low-angle inclined-plane, in the time of cutting sheet, make before cutting knifePoint of a knife first thin slice limit is cut, avoid the thin slice endoporus cutting to leave overlap, avoid occurring peripheral bead,Fold, became uneven etc.
Preferably, the angle of inclination a of described blade front end face is 7 °-8 °. The inclination of described blade front end faceAngle a refers to the angle between blade front end face and blade cross section.
Further, described blade front end face is provided with a breach near one end of described blade. Cutting knife blade just beforeFace is worn into a small size breach, plays certralizing ability in working angles, if there is no this breach, cutterTool is subject to the axial cutting force of workpiece material in process, makes cutter head place that strain occur, and causesThe even flange of sheet parts uneven thickness that scales off, has had and has relied on this indentation, there after this breachWorkpiece material can provide an axial supporting, offsets axial thrust in feeding process and reaches a powerBalance, thus the impact of cutting thrust on cutter eliminated, play the effect of centering to cutter head place.
Preferably, described notch geometry is that radius is the semi-circular arc groove of 1.2mm, and the degree of depth is 1.2mm, inclinesRake angle is 3 °-4 °, with the naturally crossing transition of described front end face. Described angle of inclination refer to semi-circular arc groove withAngle between blade front end face.
Further, described blade also comprises blade upper surface, and described blade upper surface is near one of described bladeEnd is provided with a groove. Cutting knife upper surface has a circular groove near blade place mill, can further reduceThe angle of point of a knife, makes point of a knife sharper, and is conducive to excretion, eliminates the accumulation of raw material chip.
Further, described cutting knife also comprises knife bar, and described knife bar and described blade are one-body molded, described knife barBe provided with transition arc with described blade junction.
The invention has the beneficial effects as follows: ultrathin pad special cutter is processed in a kind of turning provided by the invention,Adopt the cutting knife front end face of inclination, in the time of cutting sheet, the point of a knife before cutting knife first cut thin slice limit,The thin slice non-trimming cutting and crimping, smooth, thickness is even; Blade is provided with breach just above, is cuttingIn journey, play certralizing ability, eliminate the impact of cutting thrust on cutter; Be provided with groove by cutting knife upper surface,Further reduce the angle of point of a knife, make point of a knife sharper, be conducive to excretion, elimination raw material chipPile up.

Detailed description of the invention
The present invention is described in detail by reference to the accompanying drawings now. This figure is the schematic diagram of simplifying, only with the side of signalFormula illustrates basic structure of the present invention, and therefore it only shows the formation relevant with the present invention.
As Figure 1-4, ultrathin pad special cutter is processed in a kind of turning of the present invention, comprises knife bar 1With blade 2, blade 2 is positioned at one end of knife bar 1, and blade 2 comprises blade 21, point of a knife 22, blade front endFace 23 and blade upper surface 24, knife bar 1 is one-body molded with blade 2, and the thickness of blade 2 is less than knife bar 1Thickness, therefore, knife bar 1 and blade 2 junctions are provided with the transition arc 5 of arc, in working angles forSave raw material grinds cutter blade 2 narrowlyer as far as possible.
As shown in Fig. 3 and Fig. 5-7, blade 21 is positioned at upper end and the blade upper surface 24 of blade front end face 23Intersection, and blade 21 has angle β with the cross section of blade 2, the size of angle β is 7 °-15 °,Blade front end face 23 is an inclined-plane, and the incline direction on inclined-plane is to be provided with one of blade 21 from blade front end face 23End tilts to the other end, and the angle of inclination a of blade front end face 23 is 7 °-8 °.
