Description
Related application
The application is that exercise question is 09/965 of " saw blade " U.S. Patent application, 162 and exercise question be the partial continuous application of the PCT application PCT/US02/03272 of " improved instrument and manufacture method thereof ", these two patent applications are all comprised in this application by whole in the reference mode.
Technical field
The present invention relates to some instruments, relate in particular to a kind of method that adopts a kind of rotational processing apparatus to make a kind of improved saw blade.
Background of invention
Have several factors can have influence on the efficient of making cutting processing, these factors are service life, operator's fatigue and the inexactness of cutting of cutting tool for example.These effects limit speed and degree easily that may manufacture component.
Cutting tool has contacting repeatedly and cause wearing and tearing between cutting tool and the workpiece, and should wearing and tearing directly related with the life-span of product.Contact between workpiece and the cutting tool also can produce friction, and this friction can produce heat again, and this heat can produce negative influence to the life-span of this instrument.For example, when saw blade cut a workpiece, the side of this saw blade can contact with the side of the groove that has cut out in this workpiece.The side of common saw blade has coarse relatively fineness.Therefore, when the wear surface of this saw blade contacts with the wear surface of grooving, can cause rubbing largely, this can promptly heat this workpiece and saw blade.Temperature rise excessively can produce infringement to saw blade and/or workpiece.
Operator's fatigue also can reduce productivity ratio.The operator is tired, and the logical frictional resistance that can be cut between instrument and the workpiece amplifies.As mentioned above, when the contacts side surfaces workpiece of saw blade, between two coarse surfaces, can produce friction.This phase mutual friction is directly passed to the operator as the cutting resistance, and this cutting resistance requires the operator to apply bigger power and cuts this workpiece.
In order to make the contact between saw blade and the workpiece minimize, common saw blade is such formation, it is the width of otch (cut) (being referred to as " swage set (saw set) " usually), the width of cutting tip that can be by being used for straight blade or the whole width that is made of the tooth in the lateral shift of non-straight blade constitute, and this width dimensions is slightly greater than the blade section or the body of saw blade.The oversize meeting of this otch forms the gap between the cutting part of blade section and workpiece.The size in this gap can be changed according to the size and the type of saw blade.Can help to reduce contact between saw blade and the workpiece although increase gap between the cutting part of saw blade and workpiece, any transverse movement of saw blade still can cause this instrument to contact with the workpiece generation.
Another problem of common saw blade was actually because this gap caused, and wherein introducing this gap between the width of this sawtooth and blade section or plate is in order to alleviate above-mentioned CONTACT WITH FRICTION.Gap between this sawtooth and the blade section can make this saw blade produce swing when cut workpiece.This swing can cause the anisotropy of saw blade, thereby produces coarse cutting.But, thinking all that in most of saw blade manufacturing this is the defective that can make us accepting in the common saw blade, is very important because reduce the fatigue of operation with the life-span that prolongs instrument.
Recently, some company has begun to stamp plate in the outward appearance according to product for its tools production.For example, many companies begin its product is coated identical color or sticked some exquisite patterns so that the client can recognize the product that belongs to certain specific manufacturer's production rapidly.These colored extra benefits that pattern had are exactly some defectives and other the not crucial flaw that helps to hide in the finished product.
Product for not having coating or mopping need remove these defectives by this part is carried out surface grinding.So just unnecessarily increased the cost of the finished product of gained.
Therefore, the method that people need a kind of improved saw blade and produce a kind of saw blade, this saw blade can reduce tool wear, reduces operator's fatigue strength and improve cutting accuracy.
Summary of the invention
The present invention discloses the method that a kind of formation has the instrument of smooth surface smoothness.This method comprises adds first grinding agent in one container to.This container is arranged in an external container and some instruments wherein is housed.This internal container rotates with higher speed with respect to external container.This rotation makes the grinding agent of winning contact with the surface of this instrument.After finishing first revolving process, take out first grinding agent and second grinding agent is added in this container.And then band person second grinding agent rotates this internal container with higher speed.When the end revolving process second time, the instrument after the fine finishining is taken out from this internal container.

The specific embodiment
For the present invention is described, expressed one or more the preferred embodiments of the present invention in the accompanying drawing, but, be understandable that these structures that clearly provide and the means shown in the present invention is not limited to.
Shown in Figure 1A is the partial sectional view of common saw blade.As mentioned above, common saw blade comprises all cutting tip end width W, and this width is limited with formed interval or gap between otch in being formed at workpiece and the blade section.This cutting tip width W is limited by the whole width of skew sawtooth (be referred to as elastic dressing device (spring-setting) and shown in Figure 1A) or is limited by the developed width of straight cutting tip T (being referred to as shaped steel trimmer (swage-setting) shown in Figure 1B).Shown in Fig. 1 C is the schematic diagram that amplify the part of the side of saw blade, expressed common have resemble (yarn fabric by) brushed steel surface layer (brushed steel finish) F, this surface layer is formed at the blade section of this saw blade.The steel surface layer of band napping is normally very coarse.
Referring to Fig. 2 and 7, shown in it is saw blade 10 of the present invention.Should admit that the present invention is applicable to handsaw, bow saw and circular saw blade etc.This saw blade 10 comprises all cutting tip end width 12, and this width is determined or determined by the developed width of the cutting tip 15 on the straight saw blade (shown in Fig. 2 B) by the sawtooth 14 of the lateral shift on the non-straight saw blade (shown in Fig. 2 A), 14 ' integral width.Can clearerly be that what the employing the present invention in saw blade of this cutting tip width 12 made needn't be bigger than the width 16 of blade section 18 according to following.
Fig. 2 is the representative enlarged diagram partly of the blade section 18 of saw blade 10.This enlarged drawing has been expressed the smooth surface that forms on blade section 18 of the present invention.Especially the side surface of this blade section 18 is high accuracy polishing or the polished surface that is lower than 10Ra.In one embodiment, the fineness of the polished surface of this blade section 10 is approximately 6Ra or littler.Preferred surface smoothness at about 2Ra between the 4Ra.This fineness makes that the coefficient of friction of blade section 18 when contacting with workpiece of saw blade 10 is lower.Therefore, a kind of effect of lubricant has been played on smooth surface, makes this blade section 18 slide along the cut surface of this workpiece in fact without restriction.On the contrary, the surface smoothness of common saw blade is approximately 45Ra to 50Ra.
By form this low-friction surface on saw blade 10, the cutting tip width 12 on this saw blade 10 needn't be obviously wide than the width 16 of blade section 18, that is, cutting tip width 12 can be substantially equal to the width 16 of blade section 18.Because this low-friction surface fineness, the effect of guide has been played in the side of this blade section 18, and this guide helps to guide along a straight line or guide this saw blade 10, and therefore guides this cutting teeth 14 or most advanced and sophisticated 15.So just produce more accurate otch.On the contrary, the width of this cutting tip on common saw blade must make this blade section in use suffer restraints significantly greater than the width of blade body part.
Smooth fineness has also solved the problem that workpiece expands.When cutting wood or plastics, there is the trend (side that is otch can be moved to another side) that expands in material.Expansion can cause saw to be sandwiched in the workpiece and can not move.The mode that existing saw blade addresses this problem is that some contact with workpiece to prevent this side than the thin thickness of serrated portion for thickness by the blade section that makes saw blade.Smooth surface but of the present invention has been eliminated and has been related to any problem that workpiece expands, because low-friction surface plays the same effect in surface that is wiped with lubricant, makes this saw blade can freely cut this workpiece.
Another advantage of the present invention is the width that can reduce the cutting tip 15 in the straight saw blade.The saw blade of many metal cutting industries all adopts expensive tip to make, and this tip for example is the carbide alloy tip.As noted above, because blade section 18 now can be so that the width of blade section 16 be substantially equal to the width 12 of cutting tip, therefore the width of formed cutting tip 15 in fact can be less than the width of the cutting tip on the common saw blade.The reducing of most advanced and sophisticated 15 width can cause it obviously will save cost (that is to say that the carbide alloy of use still less) than common saw blade.
Be everlasting and carry out saw blade before the fine finishining and all can have some defectives, tiny pit and other outward appearance flaws.For example, after blade is partly carried out punching, need sometimes saw blade is placed on and carry out pickling in the acid and clean so that help.Overpickling can not produce the trend in carbon district on the surface of blade section.And, in the process that forms, on the surface of blade portion, produce oxidation scale (oxidatescale), hard spot and M-region sometimes.In the manufacture process of common saw blade, these defectives need be eliminated by a kind of grinding technics before or after heat-treating.Perhaps, after heat-treating on this blade section mopping so that cover these defectives.
Adopt above-mentioned and in the creationary technology described in the unexamined patent application 09/965,162 makes these defectives some especially remarkable because the very light that blade section is made, even therefore highlighted the existence of very little defective.
In order to address this problem, developed the method that is used to handle such as the novelty of the instrument of saw blade except a kind of.This method comprises the processing operating procedure in two stages, this step has adopted a kind of high energy rotary processor, for example be the sort of processor disclosed in the common unexamined patent application 10/326674 of " horizontal fine finishining machine " at title, this patent application integral body by reference in this application.At the rotary processor that also can in this processing procedure, use other type without departing from the scope of the invention.This method comprises: will treat that at first accurately machined this product is placed on one and has in the rotation container handling of phase I medium.This phase I medium can be chosen to be can provide desirable material removal degree.For example, in order to handle common saw blade, can select this phase I medium so that preferably include the grinding agent with a kind of higher-strength, for example diamond dust.The material of other type and product can adopt the phase I medium of other type.Make one section preset time of this rotary processor running subsequently.This time length or speed of operation will depend on various parameters phase I, for example defective what and to have surface damage degree, employed phase I medium on this product be what medium etc.This phase I operation is used to remove the carbon deposition, eliminates (blend out) hard spot, and removes after heat-treating because the variable color that heat treatment causes.
Because the phase I of the present invention relates to quick removal material, therefore adopt a kind of benefit of rotary processor to be that this rotary processor running is so that produce higher acceleration (g-force) and speed.
When the phase I finished, the accurately machined product of this process was removed from the phase I medium or the phase I medium is taken out from this container.A kind of method in back can be undertaken by these intensely processed products are installed on this rotation container handling, and this installation for example realizes by can a fixed mount being locked on this chamber wall with dismantling.This container can be turned around at an easy rate afterwards, thereby the phase I medium is emptied in the collection container, this phase I medium can be used again, regenerates or dispose.
Subsequently the second stage medium is introduced and wherein had in the container for the treatment of accurately machined product.Selected second stage medium can polish or lappingout the surface of product.Preferably, selected second stage medium will comprise a kind of grinding agent, and this grinding agent is softer than the phase I medium.Adopt second stage that this second stage medium carries out this method subsequently till this product reaches required surface smoothness.
In the embodiment of an a kind of circular saw blade of employing of the present invention, the phase I medium comprises the diamond dust grinding agent.Carry out on wherein a kind of convolver device described in the U.S. Patent application 10/326,674 that this phase I operation can be " horizontal fine finishining machine " at exercise question.This phase I turned round 30-60 minute under the speed of about 175RPM.The structure of this machine causes the speed rotation of this container with about 295RPM itself.The used time of phase I can change for example pickling degree of these conditions and degree of oxidation etc. according to the primary condition of saw blade.This initial velocity can produce the acceleration of about 16g on medium and saw blade.Phase I is used for removing some materials quickly from the surface of this saw blade.
This saw blade is taken out from this rotation container handling, heats and carry out sharpening subsequently.Then in saw blade being put back into this rotation container handling that wherein has the second stage medium.This second stage grinding agent comprises alumina abrasive.Still carry out the second stage operation on identical rotation container handling, the speed of this operation is about 120RPM and continues about 60 minutes.More preferably, this second stage can be carried out with two different speed.At first, carried out about 30 minutes, in these about 30 minutes, will make this saw blade stand the acceleration of about 16g with 175RPM.Speed with machine is reduced to about 120RPM (rotary speed of turning barrel is approximately 200RPM) then, continues about 30 minutes.This speed makes saw blade stand the acceleration of about 7g.
The saw blade that said method is produced has very bright fineness, and do not have basically can detected defective.These power also can make this surface produce cold plastic deformation, and this cold plastic deformation meeting produces higher lubricity, reduce residual stress and improve properties of materials.Therefore, under initial conditions, changed the structure of this saw blade.
Also have, use the mode in two stages different speed and acceleration can be applied on the pending parts, and adopted different combination of media.Iff adopting single phase process method, needed medium can require to underspeed in the starting stage, therefore will prolong the time of processing.
In another embodiment, produce up to the 40g acceleration on higher speed running of handling machine one and the product in container.In this embodiment, the phase I has also been adopted the diamond dust medium.This machine turns round under the speed of about 235RPM, and this rotating speed makes that the rotary speed of container is about 400RPM.So just make saw blade can stand the acceleration of about 40g.This process approximately continues 15 minutes, perhaps decides according to the initial conditions of this saw blade.
In second stage, preferably adopt aluminium oxide as medium.Still make machine rotate about 15 minutes under the rotating speed of about 235RPM, this rotating speed makes container rotate and produce the acceleration of about 40g under the rotating speed of about 400RPM in container.This speed is lowered to about 120RPM (its can so that the rotary speed of turning barrel reaches about 200RPM) subsequently and continues about 30 minutes.This speed makes this saw blade can stand the acceleration of about 7g.
Need should be appreciated that above-mentioned speed and time only are that two embodiment are illustrated.Employed in the method speed and time are depended on various Considerations, for example (diameter of external container is big more for the structure of the situation of medium (medium that wore and tore can need add processing time), machine, the speed of then allowing employing is low more, but also needs to keep or increase the speed of medium with respect to parts simultaneously) and the situation for the treatment of accurately machined parts.Also have, although the description that said method is carried out is accurately machined at being used for saw blade is carried out, this method still can be used in other products, more especially the cutting element that can be benefited from the Surface Finishing that comprises plastic deformation.
Said method has also produced extra benefit, helps to prolong the life-span of saw blade exactly.For example, this method makes the surface of saw blade have higher rust-proofing ability.This effect is that this surface can prevent to get rusty because this high speed fine-processing technique can produce a kind of surface of not gaseous occlusion.Therefore, adopt the present invention, just reduce or eliminated the purpose that is in protection fully and the needs that need on saw blade, brush antirusting paint or antirust paint.
As mentioned above, the width with blade section 18 is identical basically to the invention enables the width of tip or sawtooth.Although reduce the width at tip 15 are methods that realize this situation,, can also its thickness that equals tip 15 or sawtooth 14 substantially be realized by widening blade section 18.Blade section 18 after widening has better structural stability than the common blade section of not widening.Should additional structural stability also make this saw blade just not needing to heat-treat and to make.Therefore, the manufacturing cost of the saw blade that is obtained is lower.And thicker saw blade has higher shock resistance, and vibrations usually make operation feel tired.
Learn that by test this saw blade precise polished also reduces and/or eliminate fragility in the blade section.In common Technology for Heating Processing, can in the steel saw blade, form microcosmic and break.Breaking of these microcosmic finally will become the root of saw blade fracture failure.High speed and precision processing technology of the present invention produces multiaxial stress in the metal surface, as parts are carried out bead.So just produced the different saw blade of a kind of structure.Common bead is not used on this saw blade, because common bead is used for can causing on this saw blade to the infringement of sawtooth and even can causes surface characteristic to produce uneven change (being air spots).Precise machining process of the present invention has strengthened does not before see material behavior in saw blade.
And test shows adopts above-mentioned finishing operations can reduce the residual stress of saw blade on saw blade.Forming by blank in the technology of this saw blade, stress that can in metal, produce, especially on the sawtooth or sawtooth around.Residual stress in saw blade can cause the saw blade waist (premature warpage) that collapses too early usually, and this waist that collapses too early can cause the generation of breaking, and finally causes tool failures.Test shows, the method for this saw blade produces multiaxial stress in metal, therefore reduced the residual stress in the saw blade significantly.This has just formed a kind of fundamentally different product, and this product is very flat and be difficult for producing the waist and breaking of collapsing.
In addition, when test and detection, it is pointed out that the surface impurity that the invention enables product.Surface impurity does not have benefit in cutting material, because its acidic materials provides zone that adheres to and the grade that reduces material.In manufacture process, cutting tool all is subjected to pickling in many cases.And in the process of using cutting tool, the acidic materials generation comes from material to be cut and or owing to is exposed under certain external environment.For example, producing acidic materials concerning wood pulp in cutting process is again commonly only to have got.Surface impurity holds the place for acidic materials provide, and corrodes primer subsequently.
The polished surface of the cutting tool surface impurity that reduced significantly of the present invention.Therefore, this instrument obviously has bigger repellence to the erosion of acidic materials.When saw blade adopted tungsten carbide to make usually, this situation was even more important to saw blade.Acidic materials attempt to make cobalt sucking-off tungsten carbide this saw blade that weakens significantly thus.The invention provides a kind of saw blade, this saw blade comparatively robust and possible hardly owing to the erosion of acidic materials is degenerated.This method is not limited to stand acid material.This method can also be used for owing to the erosion that is subjected to chlorine for example or water and oxidation or the material that gets rusty and degenerate.By making the minimized of surface impurity, the present invention can suppress on the surface that this pollutant is seated in product and corrode the material of bottom.
Carry out although foregoing is the embodiment at a kind of saw blade, can also contemplate, the present invention can be used for other saw class cutting tool, for example bow saw, handsaw and band saws etc.And cutting tool (for example drill bit) and other material (for example tungsten carbide tip) that stands residual stress and acidic materials infringement that the finished product that the process high speed processing is crossed can be other type provide identical advantage.And, although the invention described above has adopted a kind of fixed mount that a plurality of saw blades are remained in this high speed centrifugation precise machining device, also can adopt a kind of less fixed mount to fix instrument (for example drill bit).Shown in Figure 8 is such example, is used for fixing a plurality of accurately machined parts for the treatment of.It is also conceivable that these parts are mounted to towards interior, thereby adopt centrifugal force to help these parts are fixed on this fixed mount.That shown in Figure 9 is another embodiment.
Although the shown fixed mount of embodiment shown in Fig. 6,8 and 9 is fixed on this inner chamber,, can expect that this fixed mount can move around this container in operation process.Determine, processed product is installed on the fixed mount of a free-floating in this container can realizes this product is carried out extra fine finishining.Especially, referring to Figure 10, shown in it is one embodiment of the present of invention, and the fixed mount that wherein maintains this instrument to be processed rolls in this container.Because this fixed mount will have the inertia resistance bigger than this fine finishining medium (being that its relative velocity ratio medium is little), thus this medium will be not only be connected on this fixed mount in instrument contact (as the effect of bead) but also can slide along the various surfaces of instrument (as the effect of polishing or lappingout).Therefore, adopt the final instrument that obtains of the present invention obviously to have better fineness than common finished product instrument.
The present invention also can be used on the various materials, for example metal, plastics and pottery.And the present invention also may be used on can using on bearing and the lining on the linear axes and also.In such an embodiment, compare with common finishing operations, this method will provide a kind of harder and more smooth surface.
This method can adopt a middle mode to control so that obtain a large amount of different finished products.For example, can control the type of running speed, medium of this precise machining device and size and mixing speed, promptly determine in finishing operations, to apply how many energy to this product so that determine this velocity inertial.This helps to determine to be applied to the cold plastic deformation on this product.
Above-mentioned advantage clearly is unpredictable and opposite with the design and the manufacturing practice of general tool.
Although adopt its exemplary embodiment to be described to the present invention, but those of ordinary skill in the art should be understood that, can be therein under the situation that does not break away from design of the present invention and scope and to its make aforementioned and other change, deletion and replenish.
