Description

Disposable type carving blade

Technical field

The present invention relates to a kind of improvement of graver, a kind of carving blade of disposable type structure is referred in particular to.

Background technology

General existing graver, mainly carves characters or carves various pattern, decorative pattern ... applied to metal surface Deng processing, refer to shown in Figure 13 to Figure 15, be the engraving cutter 30 of general whole branch solid carbide material, the engraving cutter 30 include knife bar 31 and engraving two parts of blade 32, and wherein the engraving blade 32 is by flat top 321, the right side for being located at center line Angle and set 324 structures of end cutting blade for being at least more than 5 ° with horizontal plane in end that side 322, left side 323 are enclosed Into referring to the partial enlarged drawing that Figure 15 show the engraving blade, the center line 320 of the engraving blade 32 and the knife bar center Line 310 has an appropriate eccentricity value e, and the end of the end cutting blade 324 is groove width radius Y, the carving with the value of knife bar center line 310 Groove width and be 2Y that icking tool is cut, the engraving cutter 30 is few due to cutting output, therefore mainly by the engraving blade 32 The end cutting blade 324 of eccentricity value e design, only single right edge 322 and end has cutting power, carries out carving characters, carving for shallow-layer Needle drawing sample ... waits work.

But engraving cutter 30 designs different eccentricity value e, e values from 0.01 to 0.06mm in response to different engraving groove widths Between, the Y value of milling groove width radius is between 0.05 to 0.3, and the collocation of the general e for carving cutter 30, Y value is e=0.01, Y =0.05；E=0.02, Y=0.1；E=0.03, Y=0.15；E=0.04, Y=0.2；E=0.05, Y=0.25；The grade of e=0.06, Y=0.3 Collocation, is e=0.03 as shown in figure 16 if collocation error will produce the eccentric excessive missing that can not be cut of end cutting blade 324, The collocation of Y=0.05 (and cutting groove width W=0.1mm), because eccentricity value e is wide so that the end cutting blade 324 is entirely located in knife bar The right side of center line 310 so that left side 323 of the opposite side without cutting power extends to the right side of knife bar center line 310, therefore makes Obtaining the engraving cutter 30 can not smoothly cut, and have flash and produce the phenomenon that even blade bursts apart, therefore a kind of eccentricity value e can only Arrange in pairs or groups a kind of groove width radius Y, is the processing in response to different groove width W, and consumer must buy different eccentricity value e (or different slots Wide radius Y) engraving cutter.

Separately refer to shown in Figure 13 to Figure 15, after the end cutting blade 324 and the passivation of right edge 322 machine must be used to grind sword Mouthful, recover sharp keen blade, but because the end cutting blade 324 is very small, grinding is extremely difficult, and right edge 322, left side 323 must all be ground, and stock removal must be very accurate, otherwise the center line 320 of the engraving blade 32 and knife bar center line 310 Eccentricity value e will change, if eccentricity value e will influence the Y value of the end of end cutting blade 324 and knife bar center line 310 when becoming big, Can probably make the excessive right avertence of end cutting blade 324 and positioned at the right side of knife bar center line 310 so that left side of the another side without cutting power 323 extend to the right side (as shown in figure 16) of knife bar center line 310 so that the situation that the engraving cutter 30 can not smoothly be cut, Therefore the grinding technique of the graver seems extremely difficult, and the wrong probability of mill is very high.

Refer to shown in Figure 17, be the engraving cutter 40 of disposable type structure, the end of knife bar 41 of the disposable type cutter sets one Tool rest 42, the center of screw 421 and the knife bar center line 400 of the tool rest 42 have on a small deviation value e, the tool rest 42 Lock a disposable type carving blade 50, and the disposable type carving blade 50 is in the outward appearance of a rhombus, and its one end is provided with a right cut side 51 And one left cut side 52 sandwich into a V-shape, the V-shape end be provided with one end cutting blade 53, the left cut while 52 with right cut while 51 in pair Claim shape, the intersection point of end is simultaneously located on the center line 500 of blade, and the blade is carved for the class hole 54 of locking positioned at disposable type The center of icking tool piece 50；Therefore when disposable type carving blade 50 is locked in tool rest 42, the point of a knife and knife of the end cutting blade 53 Bar center line 400 has a groove width radius Y, and the right cut side 51 of only single side and end cutting blade 53 have cutting power；If therefore Needing different groove width radius Y disposable type carving blade 50 must then arrange in pairs or groups different eccentricity value e tool rest 42；Disposable type structure Although carving after the passivation of the blade of cutter 40 without grinding again, the disposable type carving blade 50 directly more renewed, disposable type carving Icking tool piece 50 must arrange in pairs or groups the appropriate eccentricity value e of tool rest 42 according to different groove width radius Y, it is necessary to which control end cutting blade 53 will not be complete Portion is offset to the right side of knife bar center line 400, and causes the left cut side 52 without cutting function not to be offset to knife bar center line 400 Right side.

Existing engraving cutter is that the grinding of whole branch solid carbide material is formed, and must then be ground again when edge weares and teares Mill, but because stock removal and small and precision controlling must be very accurate, otherwise hold cutting blade and the trimming position without cutting power to incite somebody to action It can be misplaced, and lead to not the missing of cutting, and the eccentricity value e of engraving blade must arrange in pairs or groups with the groove width radius Y of cutting, otherwise Also the trimming of no cutting power can be made and hold the position of cutting blade to be misplaced, lead to not cutting；In addition the graver of disposable type structure Tool, although be not required to be ground cutting edge, but engraving blade eccentricity value e and groove width radius Y must arrange in pairs or groups, and otherwise still whether there is cutting power The position of trimming and end cutting blade is misplaced, and leads to not cutting missing.

In view of this, the present inventor designed for above-mentioned engraving cutter structure do not attain improve caused many missings and Inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design this case.

The content of the invention
