Background technology

Cutting die in the market mainly contains plank cutting die, plastics cutting die, irony or aluminum cutting die, acrylic cutting die etc., but topmost cutting die is plank cutting die.Namely plank cutting die is open a dress cutter seam according to the size of cross cutting blade on certain thickness plank, again blade is inserted wherein, width of slit cutting die plate filling cutter will adapt to the width of die-cutting rule, and joint-cutting wall both sides closely cooperate consistent with blade, reach the effect of fixed die cutting knife.

The processing of circle mould cutting die plate, mainly needs to process according to cutting die figure correspondence the cutter seam can installing cross cutting blade on its circular arc sheet material.

Cutter seam is generally stitched by linear pattern cutter and arc line type cutter stitches two kinds and forms, and the cutter seam total length ratio of the shared cutting die plate of linear pattern cutter seam usually to stitch total length ratio than the shared cutter of arc line type cutter seam high.Two sides that usual linear pattern cutter seam refers to cutter seam gap respectively in two parallel planes, such as, as Fig. 1 a, Fig. 1 a-1, Fig. 1 b, Fig. 1 b-1, the round mould cutting die plate with linear pattern dress cutter seam shown in Fig. 1 c, Fig. 1 c-1.

For the product of reality processing, usually occupy the majority with two kinds of linear pattern cutter seams shown in Fig. 1 a, Fig. 1 a-1, Fig. 1 b, Fig. 1 b-1 again, the linear pattern cutter seam proportion shown in Fig. 1 c, Fig. 1 c-1 is less.Except linear pattern cutter seam, other cuttves seam also has arc-shaped cutter seam as shown in Fig. 1 d, Fig. 1 d-1, and usual proportion is also less.

For the processing method of circle mould cutting die plate cutter seam, the following several mode of main employing at present: 1. carry out the method for cutting with manual electric saw; 2. carry out with the laser of laser cutting machine the method that high temperature burns cutting; 3. the method for cutting is carried out with the numerical control device installing linear saw; 4. the method for cutting is carried out with the numerical control device installing milling cutter.

Carry out the method for cutting with manual electric saw, first will draw cutting die figure by drawing instrument, then cutting die figure is attached on round mould cutting die plate, according to the lines drawn by cutting die figure, cuts with manual electric saw, process cutter seam.This processing method technological process is complicated, and labor intensity of operating staff is large, inefficiency, and the positional precision of processing cutter seam can be caused low because of the reason of electric saw hand-manipulated.

The method that high temperature burns cutting is carried out with the laser of laser cutting machine, according to the machining path of cutting die figure, controlled the relative movement of laser and circle mould cutting die plate by numerical control device, utilize the function that laser high temperature burns to cut, circle mould cutting die plate processes cutter seam.Adopt the method also can bring following problem: because laser cutting machined utilizes laser to carry out high temperature to burn cutting, can cause producing a large amount of flue dust and niff in process, contaminated environment and the health affecting people; Round mould cutting die plate cutter seam both sides after laser cutting machined can leave the carburization zone of high temperature sintering, carburization zone reduces the chucking power of cutter seam to cross cutting blade, circle mould cutting die plate carries out after cross cutting processes a period of time, die-cutting rule sheet on circle mould cutting die plate there will be loosening and tilts, and the service life of impact circle mould cutting die plate and round mould cutting die plate add the machining accuracy in man-hour at cross cutting; The carburization zone of high temperature sintering can because of stressed and cracked in die cutting process, and the chip produced can affect the quality of the die cutting product having dust-proof requirement; During laser cutting machined circle mould cutting die plate, its laser generator or laser tube also need gas and the electric power of at substantial.

Carry out the method for cutting with the numerical control device installing linear saw, be the machining path according to cutting die figure, sawed by numerical control device control linear and justify the relative movement of mould cutting die plate, utilize the reciprocating motion cutting of linear saw, circle mould cutting die plate processes cutter seam.Because the thickness of circle mould cutting die plate reaches 12mm ~ 15mm, and the width of cutter seam is generally 1.43mm, so the linear saw slender construction of processing circle mould cutting die plate cutter seam, its rigidity is not enough, linear saw is easily broken, the frequency moving back and forth cutting improves limited, and process velocity is confined to the frequency that linear saw moves back and forth cutting, therefore this processing method inefficiency.In addition, due to the reverse active force backward of processing object that saw blade is subject in a forward direction, and saw blade do move up and down time, sawtooth is subject to upper and lower opposition, saw blade often produces deformation adding man-hour, comprises the deformation of saw blade linear direction and the deformation perpendicular to linear direction.In addition, saw blade itself has elasticity, therefore also can produce certain error when installing saw blade.Due to the stress and deformation of saw blade itself, the error of lathe, characteristic of processing object etc. factors; above-mentioned linear saw usually can produce mismachining tolerance when each machining; each mismachining tolerance size is also dissimilar, and this error can be accumulated, till the deformation quantity that saw blade is maximum.Because existing saw blade sawtooth in process contacts with processing object always, thus cause last processing deformation to eliminate, retain always and accumulate, forming accumulated error, not only affect machining accuracy, also can cause shorten the service life of saw blade.

Carry out the method for cutting with the numerical control device installing milling cutter, namely according to the machining path of cutting die figure, controlled the relative movement of milling cutter and circle mould cutting die plate by numerical control device, utilize the circumgyration incision of milling cutter, circle mould cutting die plate processes cutter seam.But because the thickness of circle mould cutting die plate reaches 12mm ~ 15mm, and the width of cutter seam is generally 1.43mm, so the milling cutter construction of processing circle mould cutting die plate cutter seam is elongated, its rigidity is not enough, easily fracture when high speed milling is processed, process velocity is limited to, therefore this processing method inefficiency.

Detailed description of the invention

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing of the embodiment of the present invention, the technical scheme of the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of protection of the invention.

Unless otherwise defined, technical term used herein or scientific terminology should be in field belonging to the present invention the ordinary meaning that the personage with general technical ability understands." first ", " second " that use in patent application specification of the present invention and claims and similar word do not represent any order, quantity or importance, and are only used to distinguish different parts.Equally, the similar word such as " " or " " does not represent that quantity limits yet, but represents to there is at least one.

Because the line style of circle mould cutting die plate cutter seam is made up of linear pattern and arc line type two kinds, and the shared length ratio of linear pattern cutter seam is higher than the shared length ratio of arc line type cutter seam usually, the linear pattern cutter seam that in circular saw tool setting suture type, proportion is high can be utilized to carry out high-speed cutting processing, complete most of cutter seam processing operation.Such as, the schematic diagram that stitches for linear pattern cutter shown in circular saw manuscript 1a of Fig. 2 a; The schematic diagram that Fig. 2 b stitches for linear pattern cutter shown in circular saw manuscript 1b).

Because circular saw is have employed the mode that circular saw blade rotates sawing for the processing of cutting die plate, therefore, certain undressed part be remained at the two ends of processed groove (for installing the dress cutter seam of blade namely), as R1 part in fig. 2 a, being similar to triangle.For these residual fractions, processing cannot be completed with circular saw, if but do not remove this residual fraction, then can not form completely through working groove, the machining accuracy of dress cutter seam can be affected, the machining accuracy particularly on blade lengths direction.

According to embodiments of the invention, the residual approximate undressed part of triangular form in two ends of the linear pattern cutter seam processed can not be carried out for circular saw, milling cutter or linear saw can be utilized to process.

Such as, stitch the residual undressed part of approximate triangular form in two ends for after the circular saw processing linear type cutter seam shown in Fig. 2 a at cutter, continuation processing can be carried out with milling cutter to these residual fractions, as shown in Figure 2 c; Stitch the residual undressed part of approximate triangular form in two ends for after the circular saw processing linear type cutter seam shown in Fig. 2 b at cutter, also can carry out continuation processing with milling cutter to these residual fractions, as shown in Figure 2 d.

For shorter linear pattern cutter seam, such as length is less than the cutter seam of circular saw diameter, and circular saw may not be cut and wear round mould cutting die plate, can remain the undressed part R2 of arc, such as, as shown in Figure 2 e.Also can process this undressed part R2 with milling cutter or linear saw.

This advantage utilizing circular saw can cut linear pattern cutter seam fast, in conjunction with milling cutter or the linear process equipment sawing Combined machining circle mould cutting die plate, both can solve and carry out technological process complexity in the method for cutting with manual electric saw, labor intensity of operating staff is large, inefficiency, the problem that the positional precision that cutter stitches is low; Also can solve simultaneously and carry out high temperature with the laser of laser cutting machine and burn contaminated environment in the method for cutting, the machining accuracy that unhealthful, mould cutting die plate is justified in impact and service life, affect the problem of the quality of die cutting product, the gas of at substantial and electric power; Can also solve and carry out the method for cutting and the ineffective problem of carrying out the method for cutting with the numerical control device installing milling cutter with the numerical control device installing linear saw.Further, add man-hour with milling cutter to the remainder after circular saw processing, the thickness of this remainder on milling cutter machine direction is less than the thickness of cutting die plate usually, therefore, can process with higher process velocity.

Process equipment according to the embodiment of the present invention comprises circular saw, also comprises milling cutter and/or linearly saws.Wherein, the width that milling cutter processing diameter and the dress cutter processed stitch matches, to meet the requirement adding frock cutter seam on cutting die plate.Linear saw can be saw blade, garland saw (flexible or rigidity) etc.Especially, carrying out adding the accumulated error produced man-hour to eliminate linear saw tool setting template, according to embodiments of the invention, additionally providing a kind of novel linear saw.

Fig. 3 a and Fig. 3 b is the schematic diagram of the basic structure of linear saw according to the embodiment of the present invention.Wherein, Fig. 3 a is the front view of linear saw, and Fig. 3 b is the side view of linear saw.Fig. 3 a and Fig. 3 b embodies two kinds of structure dividing mode.A kind of mode carries out dividing from the angle of the outside effect of linear saw, comprising: cutting tip I and support section II; Another kind of mode carries out dividing from the angle of the inside effect of linear saw, comprising: processing department 1, empty avoiding portion 2 and fixed part 3.From the angle in space, also can think, first kind of way is the angular divisions of width from Fig. 3 a; The second way is the angular divisions of length direction (linearly sawing bearing of trend) from Fig. 3 a and Fig. 3 b.

See Fig. 3 a, in the first manner description scheme, then this is linearly sawed and comprises: for carrying out the cutting tip I of machining to processing object, such as, sawtooth; And for supporting the support section II of this cutting tip I, i.e. hump.

The said linear saw of the embodiment of the present invention can be the saw blade in sawtooth orientation with certain length." linearly saw linear direction " or direction that " linear sawline bearing of trend " and sawtooth in the cutting tip I linearly sawed arrange identical or parallel.Because saw blade has certain length, and its machined surface is thinner, and support section II can play the effect supporting saw blade, improve linear intensity of sawing, and also can facilitate the installation and removal of saw blade.

Alternatively, such as, the rigid material plate of strip can be made into cutting tip I along the side on its long limit, the opposite side on its long limit is made into support section II, and support section II can be only rigidity raw material itself, also can process further, such as, polished further by support section II, calcining, its shape, structure, thickness etc. all can be identical or different with cutting tip I.

Alternatively, support section II can be made up of the multistage of difformity and thickness, namely has different shapes and thickness at diverse location.Alternatively, other materials can be installed on the support section II of rigid material reinforce linear saw and support.

Alternatively, cutting tip I and support section II, except one-body molded, also can be assembled relation.Cutting tip I directly can be carried out assembling and being connected with the support section II made separately, be formed and linearly saw.

Description scheme in the second, then comprise according to the linear saw of the embodiment of the present invention: processing department 1, empty avoiding portion 2 and fixed part 3.

Processing department 1, empty avoiding portion 2 and fixed part 3 also can be one-body molded or assembling is formed.

As shown in Figure 3 a, processing department 1 is the serrate part of linear saw band, includes the appropriate section of the support section II of cutting tip I and one or connection with it.The direction of the sawtooth teeth of cutting tip I is schematic.

Empty avoiding portion 2 between processing department 1 and fixed part 3, with processing department 1 and/or fixed part 3 is one-body molded or assembly and connection.Empty avoiding portion 2, linearly sawing in the process of processing object, through working groove, but is not subject to processing the inwall active force of seam in the process of passing working groove.That is, in empty avoiding portion 2 through in the process of processing object, empty avoiding portion 2 can not clamp by processed groove both sides inwall, also can not offset with working groove top side inwall (linearly sawing the inwall that the direction of advance of processing contacts with working groove), thus processing object also can not to the effect of linear saw forces occurring.Like this, as Such analysis, linear saw (comprising processing department 1) is returned to straight line Working position, so can eliminate the accumulated error in process under the effect of the deformation recovery power of linear saw self.

According to embodiments of the invention, the length in empty avoiding portion 2 is greater than the thickness of processing object, and width is less than the Breadth Maximum of processing department 1, and thickness is less than the width of working groove, like this, when empty avoiding portion 2 is by processing object, can ensure both can not the inwall clamping of processed groove both sides within certain period.Also can not offset with working groove top side inwall, thus can not by the active force of processing object within this period.The length of described period depends on the length in empty avoiding portion 2 and the difference of processing object thickness, and linear saw movement angle in the direction of extension and speed.

Specifically, as shown in Figure 3 a, the width L2 in empty avoiding portion 2 is less than the Breadth Maximum L1 of processing department 1, and wherein the Breadth Maximum of processing department 1 is actually sawtooth maximum elongation in a forward direction and the width sum of hump.If the width in empty avoiding portion 2 is less than the Breadth Maximum of processing department 1, after processing department 1 pair of processing object carries out machining and moves in a forward direction, empty avoiding portion 2 can continue to move a segment distance in a forward direction (such as, distance L=L1-L2), and in the process of empty avoiding portion 2 movement, empty avoiding portion 2 can not touch processing object in a forward direction, thus can not be subject to active force in a forward direction.

As shown in Figure 3 b, the thickness W2 in empty avoiding portion 2 is less than the width (the processing distance on width) of working groove.Width (the processing distance on width) due to working groove depends on the working width of processing department 1, and that is, the width of working groove equals or slightly larger than the maximum machining width of processing department 1.When processing department 1 is at the upper sawtooth arranged in a straight line of bearing of trend (bearing of trend), namely the width of working groove equals or slightly larger than thickness (width) W1 of sawtooth.

After processing department 1 pair of processing object carries out machining and moves in a forward direction, empty avoiding portion 2 can continue to move a segment distance in a forward direction (such as, distance L=L1-L2), move through working groove in the direction of extension simultaneously, thickness due to empty avoiding portion 2 is less than the width of working groove, make in the process of empty avoiding portion 2 movement, empty avoiding portion 2 can not clamped by the inwall of processed groove both sides at width, thus empty avoiding portion 2 all can not be subject to limiting its active force of replying from processing object in direction of advance and width.

Similar aforementioned, within a process-cycle, after processing department 1 pair of processing object carries out machining, can be bent linear saw entirety (comprising processing department 1 and empty avoiding portion 2) deformation, like this, even if the thickness in empty avoiding portion 2 is less than the width of working groove, a side in empty avoiding portion 2 also likely contacts with the respective side inwall of working groove, but this side inwall is also rightabout active force with deformation to the active force in empty avoiding portion 2, can not hinder the deformation recovery of linear saw.Alternatively, the thickness in empty avoiding portion 2 is set, makes the difference of the maximum machining width of processing department 1 and this thickness be greater than the deformation side-play amount of empty avoiding portion 2 at width, thus empty avoiding portion 2 is not contacted with working groove inwall when passing working groove.So when empty avoiding portion 2 is by processing object, empty avoiding portion 2 does not contact with processing object completely, thus linearly saws total detachment processing object, the deformation of linear saw is replied.

Embodiment according to Fig. 3 a and Fig. 3 b, can realize empty avoiding portion 2 with the support section II without cutting tip I.Such as, can remove or sawtooth is not installed, thus reducing the width of direction of advance; Because cutting tip I is identical at width thickness with support section II, by thin that this does not have a support section II of cutting tip I all or part of to realize the minimizing of width thickness.

Also can there be sawtooth in empty avoiding portion 2, only these sawtooth teeth are less than the maximum length of teeth in direction of advance of cutting tip I in the maximum length of direction of advance, or these sawtooth teeth and its corresponding support section II are less than cutting tip I and its corresponding support section II on the whole in the maximum length of direction of advance in the maximum length of direction of advance on the whole.Consider that time of deformation and empty avoiding portion 2 movement velocity in direction of advance replied by linear saw, require that empty avoiding portion 2 can with processing object non-contiguously at forward direction motion one segment distance, realizing empty avoiding portion 2 with the support section II without cutting tip I is schemes that a kind of ratio is easier to realize.

Alternatively, increase the maximum machining width of processing department 1 by structures such as sawtooth open circuits, thus the thickness that need not thin without the support section II of cutting tip I is to realize empty avoiding portion 2, and the thickness in empty avoiding portion 2 also can be made to be less than the maximum machining width of processing department 1.

The above-mentioned scheme that thins is that the thickness of support section II by not having cutting tip I reduces and realizes empty avoiding portion 2.Part or all the thickness of this part support section II can be reduced, as long as the length meeting the part (empty avoiding portion 2) that thickness reduces is greater than the thickness of processing object.Similarly, by thinning the thickness arranging empty avoiding portion 2, make the difference of the maximum machining width of processing department 1 and this thickness be greater than the deformation side-play amount of empty avoiding portion 2 at width, thus empty avoiding portion 2 is not contacted with working groove inwall when passing working groove.

Alternatively, whole support section II is thinned, or use thickness to be less than the support section II of cutting tip I, the processing in empty avoiding portion 2 can be made so simpler.In order to ensure the integral hardness of linear saw, empty avoiding portion 2 still needs to have certain thickness.

In the scheme of Fig. 3 a and Fig. 3 b, the thickness of the partial continuous length of the support section II of cutting tip I is not had to be less than the maximum machining width (equaling the maximum machining width of processing department 1) of cutting tip I, and using the support section II of this part as empty avoiding portion 2.Alternatively, processing makes do not have the thickness of whole continuous lengths of the support section II of cutting tip I to be less than the maximum machining width of cutting tip I, and using the support section II of this part as empty avoiding portion 2, the utilization ratio of linear saw length can be improved, make the processing object of corresponding fixed thickness use shorter linear saw.

Alternatively, the length in processing department 1 and empty avoiding portion 2 can adjust according to the thickness of processing object.This adjustment can be the linear saw (comprising processing department 1 and the empty avoiding portion 2 of different length) of design different size, also can be to design the variable linear saw in empty avoiding portion 2.As previously mentioned, the length in empty avoiding portion 2 is greater than the thickness of processing object.Alternatively, the length of processing department 1 also can be greater than the thickness of processing object.The cutting output of processing department 1 pair of processing object can be increased like this.Consider that linear saw entire length lengthens and may reduce its rigidity, therefore, the length in overall thinking processing department 1 and empty avoiding portion 2 to configure.

Fixed part 3 is arranged on the end of linear saw, for gripping from outside to linear saw.In the scheme of Fig. 3 a and Fig. 3 b, all there is fixed part 3 at the two ends of linear saw, two ends can be realized and fix.Alternatively, also only fixed part 3 can be at one end set, carry out one end and fix.Or, also directly can clamp processing department 1 and/or the empty avoiding portion 2 of linear saw, thus without the need to arranging fixed part 3.As shown in Figure 3 a and Figure 3 b shows, fixed part 3 can be machined described processing department 1 and empty avoiding portion 2 remaining part afterwards to original strip section, therefore its width in a forward direction can be substantially equal to processing department 1 width in a forward direction (Fig. 3 a), its thickness in the direction of the width can be substantially equal to processing department 1 thickness in the direction of the width (Fig. 3 b).Like this, not only simplify process (without the need to processing separately fixed part 3), fixed part 3 can also be made to have certain width and thickness, clamping of being more convenient for, rigidity is also stronger.Alternatively, fixed part 3 also can have other shape, such as, hook-shaped, for being fixed on the clamping and releasing structure etc. (such as clamping device head 1032) of sychronisation.In addition, the thickness of fixed part 3 and width are generally no more than thickness and the width of processing department 1 respectively, and such fixed part 3 can easily move in and out from processing seam together with processing department 1.

Linear saw can extend linearly direction along instrument and moves under automatic or manual drives, and carries out translational motion extending linearly in the vertical plane in direction with instrument.The motion that instrument extends linearly direction comprises only to one-way movement and the two-way back and forth movement in a direction.Linear saw can be in the optional position in three dimensions, and no matter in what position, the direction that extends linearly of linear saw all refers to the length direction that its sawtooth arranges.Such as, when the processing object flat sheet using linear saw level of processing to place, the sawtooth orientation of linearly sawing and horizontal plane are placed, namely place with processing object board material vertical, then the motion of linear saw comprises: extend linearly moving of direction along instrument, namely perpendicular to the lengthwise movement in the direction up or down (corresponding to aforesaid bearing of trend) of horizontal plane; And, with the described translational motion campaign extended linearly in the vertical plane in direction, such as, march forward and/or the motion of width.If linear saw is placed on the position angled with horizontal plane, so, instrument extends linearly the orientation that direction still refers to linear saw sawtooth, and this direction is now angled with horizontal plane too; And with described to extend linearly the vertical plane in direction angled with horizontal plane too.

According to embodiments of the invention, when the processing department 1 of linear saw acts on processing object, both did moving along its bearing of trend, also did the translational motion in the plane vertical with its bearing of trend; When empty avoiding portion 2 is by processing object, linear saw both did moving along its bearing of trend, also did the translational motion in the plane vertical with its bearing of trend.

A processing department 1 and an empty avoiding portion 2 is included according to the linear saw of the embodiment of the present invention shown in Fig. 3 a and Fig. 3 b.From the direction of sawtooth teeth, namely to the direction that processing object cuts, processing department 1 is positioned at the top in empty avoiding portion 2, and the two does not intersect.Alternatively, according to other embodiments of the invention, empty avoiding portion 2 can be positioned at the top of processing department 1, as shown in figures 4 a and 4b.

Alternatively, one or more processing department 1 can also be comprised according to the linear saw of the embodiment of the present invention, and one or more empty avoiding portion 2.Alternatively, processing department 1 and empty avoiding portion 2 can occur at interval; Alternatively, processing department 1 and empty avoiding portion 2 can occur in pairs; Alternatively, the quantity in empty avoiding portion 2 can be less than or equal to or greater than the quantity of processing department 1, such as, linear saw can comprise two processing departments 1 and an empty avoiding portion 2 (as Fig. 5 a, Fig. 5 b and Fig. 5 c), or, linear saw can comprise a processing department 1 and two empty avoiding portions 2 (as Fig. 6 a, Fig. 6 b and Fig. 6 c), or, linear saw can comprise two sections of processing departments 1 and two sections of empty avoiding portions 2, etc.Like this, according to the processing object of varying strength different-thickness, the linear saw of different structure can be chosen, also according to different machining accuracies, the linear saw of different structure can be selected.

If linear saw has multiple empty avoiding portion 2, the length in so each empty avoiding portion 2 is generally all greater than the thickness of processing object, and its width is less than the width of processing department 1, and its thickness is less than the maximum machining width of processing department 1.

Below for several linear saw structure, be described to its movement locus with to the process of processing object.

As mentioned above, Fig. 4 a, Fig. 4 b and Fig. 4 c show a kind of structure of the linear saw of the embodiment of the present invention.See Fig. 4 a, Fig. 4 b and Fig. 4 c, linear saw comprises processing department 1 and an empty avoiding portion 2, and processing department 1 under, empty avoiding portion 2 is upper.

Linearly to saw the machined surface of the processing object perpendicular to horizontal positioned, processing department 1 is first by the machined surface of processing object, and then, empty avoiding portion 2 is again by the machined surface of processing object.To linearly saw bottom, be placed on the initial position of the edge upper surface of processing object, after linear saw initial position is determined, linear saw moves downward along saw blade linear direction, carry out the translational motion of direction of advance simultaneously, in process, the frictional force that linear saw receives the resistance of direction of advance and the resistance of saw blade linear direction and produces because of chucking power and the resistance that offsets, saw blade there will be Bending Deformation, the deformation of saw blade causes saw blade Working position to depart from or machine direction skew, the position of saw blade and rectilinear slot to be processed be not on same straight line, when the end of processing department 1 leaves processing object, the empty avoiding portion 2 of linear saw is through processing object, now, linear saw is still while carry out the motion of linear direction, while carry out the motion of direction of advance, due to the thickness of whole support section II, or at least the thickness of the support section II at place of empty avoiding portion 2 is less than the thickness (equaling the maximum machining width of processing department 1 in this embodiment) of cutting tip I, therefore, when empty avoiding portion 2 is by processing object, linear saw can not clamp in processed good gap, thus linear saw can recover deformation, under the rigid return power of saw blade itself and/or the stretching action at linear saw two ends, linear saw is returned to rapidly straight line Working position, still processes according to original linear position, reaches the effect correcting skew, eliminates the generation of accumulated error.

When empty avoiding portion 2 is by processing object, the stand out (L1-L2 in similar earlier figures 3a) due to processing department 1 and empty avoiding portion 2 equals the length X of sawtooth teeth alternatively _sT, thus when empty avoiding portion 2 is by processing gap, empty avoiding portion 2 is generally less than these sawtooth teeth length X at direction of advance (direction of advance) forward travel distance _sT, reach at most the distance of sawtooth teeth length.Like this, empty avoiding portion 2 can be made not contact with processing object in a forward direction.In order to meet this condition, usually, in empty avoiding portion 2 by the time of processing object, Z is met ₂/ V _2Z≤ X _sT/ V _2X, wherein, Z ₂the length (bearing of trend) in empty avoiding portion, X _sTthe length (direction of advance) of sawtooth teeth, V _2Xand V _2Zempty avoiding portion 2 respectively by during processing object in direction of advance with at the speed of bearing of trend or average speed.

When empty avoiding portion 2 is completely by processing gap, or when linearly sawing stop motion or change track, linear saw completes this cutting carried out processing object.

As previously mentioned, alternatively, the difference of the thickness in empty avoiding portion 2 and the maximum machining width of processing department 1 is greater than the side-play amount that saw blade produced before this empty avoiding portion 2 is by processing object, like this, when empty avoiding portion 2 is by processing object, cutting tip I and the support section II of whole linear saw all do not contact with processing object, and linear saw can not the clamping of processed good gap.

Next, alternatively, linear saw only does one-way movement on linear bearing of trend, and does not continue to advance along direction of advance, so, under the drive of motor, or under the drive of return mechanism in numerically controlled processing equipment, or manually mobile linear saw to the original position of second process-cycle, now first process-cycle terminates, such as, the upper surface position of processing plate still got back to by linear saw, carries out the processing of second period.By that analogy, processing object is processed.

Alternatively, adopt the mode of Reciprocated cutting, stock-removing efficiency is higher.At this moment, linear saw moves reciprocatingly on linear bearing of trend, aforesaid cutting is actually half period, i.e. the first half period, then, linear saw carried out for the second half period, and linear saw carries out in move upward (direction contrary relative to the cutting direction of the first half period) along linear direction, and empty avoiding portion 2 first passes through processing object.

During this, if be less than or equal to sawtooth teeth length at the horizontal forward travel distance in the first half period empty avoiding portion 2, so in the second half process-cycles, moving along linear sawline direction can only be done by empty avoiding portion 2, and does not do moving along direction of advance.This is because, if the first half period empty avoiding portion 2 forward travel distance has equaled the length of sawtooth teeth, so the second half period, moving along linear sawline direction is only done in empty avoiding portion 2, do not do the translational motion along direction of advance, otherwise empty avoiding portion 2 will not advance space.

Or in the second half period, moving along linear sawline direction had both been done in empty avoiding portion 2, did again the translational motion along direction of advance, still needed at the forward travel distance of the second half period and the forward travel distance sum of the first half period the length being less than or equal to sawtooth teeth.This continuous motor pattern in a forward direction is more conducive to controlling linear saw.

Empty avoiding portion 2 is by after processing object, and processing department 1 again by processing object, and is cut processing object again, and the second half period terminated.

Due in next cycle (second process-cycle), first carry out the cutting of processing department to processing object, therefore, the cumulative maximum error that in fact empty avoiding portion 2 can eliminate is the margin of error of reciprocal twice cutting.

In the process-cycle afterwards, linear saw proceeds direction of advance translational motion and moving along linear direction again, by that analogy, processes processing object.

If linear saw has multiple processing department 1 and multiple empty avoiding portion 2, then processing department 1 and empty avoiding portion 2 sequentially pass through the machined surface of processing object successively, and processing department 1, when by machined surface, contacts machining object with processing object; When empty avoiding portion 2 is by machined surface, not by the clamping of processing object, reply deformation.

Fig. 5 a, Fig. 5 b and Fig. 5 c show the another kind of structure of the linear saw according to the embodiment of the present invention.See Fig. 5 a, Fig. 5 b and Fig. 5 c, linear saw comprises two processing departments, processing department 1A and processing department 1B, and an empty avoiding portion 2, and empty avoiding portion 2 is at two between processing department 1A and 1B.

Linearly to saw the machined surface of the processing object perpendicular to horizontal positioned, be processed as example to it, processing department 1A is first by the machined surface of processing object, and then, empty avoiding portion 2 is by the machined surface of processing object, and processing department 1B is again by the machined surface of processing object afterwards.

By the initial processing position point being placed on the edge upper surface of processing object bottom linearly sawed, carry out the processing of one-period.After linear saw initial position is determined, linear saw carries out carrying out longitudinally moving downward and in the machined surface of the processing object vertical with instrument linear direction, carrying out the translational motion of direction of advance along linear direction, namely the processing department 1A of first linear saw carries out the translational motion of direction of advance and carries out longitudinal direction along linear direction and move downward, in the process of processing department 1A machining object, linear saw receives the resistance of direction of advance and the resistance of saw blade bearing of trend and frictional force, saw blade there will be Bending Deformation, the deformation of saw blade causes saw blade Working position to depart from or machine direction skew, the position of saw blade and rectilinear slot to be processed be not on same straight line, when the end of processing department 1A leaves processing object, the empty avoiding portion 2 of linear saw is through processing object, now, linear saw is still while carry out the motion of linear direction, while carry out the motion of direction of advance, due to the thickness of whole support section II, or at least the thickness of place of empty avoiding portion 2 support section II is less than the thickness of cutting tip I, therefore, when empty avoiding portion 2 is by processing object, linear saw can not clamp in processed good gap, thus linear saw can recover deformation, under the rigid return power of saw blade itself and/or the stretching action at linear saw two ends, linear saw is returned to rapidly straight line Working position, still processes according to original linear position, reaches the effect correcting skew, eliminates the generation of accumulated error.

Similar aforementioned, when empty avoiding portion 2 is by processing object, empty avoiding portion 2 is generally less than the sawtooth teeth length of processing department 1A at the forward travel distance of direction of advance, is no more than at most sawtooth teeth length.

Subsequently, processing department 1B by processing object, and cuts processing object, and linear saw proceeds longitudinally to move downward along linear direction, and carries out the translational motion of direction of advance.Process in the process of plank sheet material at processing department 1B, linear saw still can receive the resistance of direction of advance and the resistance of saw blade bearing of trend and frictional force, may Bending Deformation be there is in saw blade, the deformation of saw blade likely causes saw blade Working position to depart from or machine direction skew, and the position of saw blade and rectilinear slot to be processed be not on same straight line.

Alternatively, when the end of processing department 1B leaves processing object, can control linear saw the speed of service or movement locus, make it slow down or stop motion.

Next, alternatively, linear saw only extends linearly on direction at it and carries out one-way movement, driven by motor can be used, or a response agency is set on numerical control device drives, or Non-follow control, make linearly to cut the original position reaching second process-cycle, now first process-cycle terminates.After second process-cycle terminates, under the drive of motor, or manually move the original position linearly cutting next cycle, linear saw carries out the processing in the 3rd cycle, by that analogy, processes processing object.

Alternatively, linearly saw carries out upper and lower reciprocating motion, and so, aforesaid cutting is actually half period, i.e. the first half period, and then, linear saw carried out for the second half period, and the processing department 1B linearly sawed, empty avoiding portion 2 and processing department 1A are successively by processing gap.In this second half period, linear saw carries out longitudinally moving upward and carrying out translational motion perpendicular on the processing plane of linear direction along linear direction, processing department 1B first passes through processing object, processing object is cut, then the empty avoiding portion 2 of linear saw passes through processing object, when empty avoiding portion 2 is by processing object, linear saw adds the error produced man-hour and can be corrected and recover, and the margin of error at this moment eliminated is the margin of error that twice cutting produces; Finally, processing department 1A again by processing object, and cuts processing object, and first process-cycle terminates.

Due in next cycle (second process-cycle), first carry out the cutting of processing department to processing object, therefore, the cumulative maximum error that in fact empty avoiding portion 2 can eliminate also is the margin of error of reciprocal twice cutting.

Second process-cycle, linear saw continues to move downward forward again, by that analogy, processes processing object.

As compared to the linear saw structure shown in Fig. 4 a, Fig. 4 b with Fig. 4 c, the linear saw structure shown in Fig. 5 a, Fig. 5 b and Fig. 5 c is provided with a processing department by increase, can increase cutting output.

Fig. 6 a, Fig. 6 b and Fig. 6 c show another structure of the linear saw according to the embodiment of the present invention.See Fig. 6, linear saw comprises two empty avoiding portions, empty avoiding portion 2A and empty avoiding portion 2B, and a processing department 1, and processing department 1 is between empty avoiding portion 2A and empty avoiding portion 2B.

Linearly to saw the machined surface of the processing object perpendicular to horizontal positioned, example is processed as to it, empty avoiding portion 2A first by the machined surface of processing object, then, processing department 1 is again by the machined surface of processing object, and the portion 2B of empty avoiding is afterwards again by the machined surface of processing object.Due to empty avoiding portion 2A to processing object without shear action, through hole can be set by the initial manufacture position of processing object and make empty avoiding portion 2A be passed through processing object.

Or directly the lower end of processing department 1 is placed in the initial processing position of processing object, makes processing department 1 first by the machined surface of processing object, then empty avoiding portion 2B is again by the machined surface of processing object.

By linearly sawing the initial processing position point being placed on processing object, carry out the processing of one-period.After processing starts, linear saw carries out the translational motion of direction of advance and carries out longitudinal direction along linear direction and move downward, such as, according to the aforementioned the scheme directly lower end of processing department 1 being placed in the initial processing position of processing object, the processing department 1 of linear saw is carried out the translational motion of direction of advance and is carried out longitudinal direction along linear direction and move downward, in the process of processing department 1 machining object, linear saw receives the resistance of direction of advance and the resistance of blade direction and frictional force, saw blade likely there will be Bending Deformation, the deformation of saw blade may cause saw blade Working position to depart from or machine direction skew, the position of saw blade and rectilinear slot position to be processed be not on same straight line, when processing object is left in the upper end of processing department 1, the empty avoiding portion 2B of linear saw is through processing object, now, linear saw is still while carry out the motion of linear direction, while carry out the motion of horizontal direction of advance, thickness due to whole support section II or at least support section II at 2B place of empty avoiding portion is less than the thickness of cutting tip I, therefore, when empty avoiding portion 2B is by processing object, linear saw can not clamp in processed good gap, linear saw is so can recover deformation, under the rigid return power of saw blade itself and/or the stretching action at linear saw two ends, saw blade is returned to rapidly straight line Working position, still processes according to original linear position, reaches the effect correcting skew, eliminates the generation of accumulated error.

Under the pattern moving back and forth processing, empty avoiding portion 2B is double by the processing gap on processing object, and during by processing object, its horizontal forward travel distance sum is generally less than the sawtooth length of processing department 1, the distance of maximum advance sawtooth length.

When empty avoiding portion 2B is upwards again by after processing object, the processing department 1 of linear saw passes through processing object, when processing department 1 is by processing object, processing object is processed, equally, linear saw, in this working angles, still may produce deformation and cut orbit displacement, but this error can at empty avoiding portion 2A subsequently by being eliminated during processing object and being corrected.At empty avoiding portion 2A by after processing object, first process-cycle terminates.

Second process-cycle, linear saw continues to move downward forward again, and the 3rd process-cycle, linear saw continues to move downward forward again, by that analogy, processes processing object.

Under reciprocal cooked mode, in a complete machining cycle, linear saw structure shown in Fig. 4 a, Fig. 4 b and Fig. 4 c and the linear saw structure shown in Fig. 5 a, Fig. 5 b and Fig. 5 c have all carried out by eliminating processing department during processing gap the error that twice cutting accumulate in an empty avoiding portion, and the linear saw structure shown in Fig. 6 a, Fig. 6 b and Fig. 6 c, because the two ends up and down in processing department are all provided with empty avoiding portion, therefore after processing object being cut, error can be eliminated in time at every turn, prevent error accumulation better effects if.

Adding man-hour, linear saw needs accurately to control in the pace of direction of advance, makes the saw blade of linear saw have the sufficient empty avoiding time.That is, the empty avoiding portion of linear saw when moving by the speed of processing object with linearly saw the velocity of displacement advanced on processing object and needs to match, empty avoiding portion was no more than by the time of processing object and linearly saws advance sawtooth teeth apart from the required time.

Because the translational motion of direction of advance is integrally done in the processing department of linearly sawing and empty avoiding portion, also do the one-way movement along saw blade linear direction or reciprocating motion simultaneously, like this, after processing department is cut processing object, empty avoiding portion passes through processing object, in the process of empty avoiding portion by processing object, linear saw is still in horizontal advance, empty avoiding portion is longer by the time of processing object, the lateral displacement that linear saw advances is larger, if empty avoiding portion is by the overlong time of processing object, so linear saw proceeds to the region that processing object is not cut, so linear saw cannot advance, or the wearing and tearing of saw blade or the skew of angle may be caused, produce and cut error.If empty avoiding portion is too short by the time of processing object, then the lateral displacement of linear saw advance is too small, much smaller than there being serrated portion sawtooth teeth length, processing department just starts to process again next time, the major part in the gap of having cut may be caused to be cut one time again, stock-removing efficiency is too low, loses time and resource.

On the other hand, empty avoiding portion also will enough make the deformation of whole linear saw recover completely by the time of processing object, thus plays the effect eliminating accumulated error.

Therefore, linear saw empty avoiding portion needed to be no more than the time needed for linear saw advance displacement sawtooth teeth length by the time of processing object, but can not be excessively little, suitably can adjusting according to factors such as the material of processing object and machining accuracies, making the empty avoiding portion of linear saw need to match by the speed of processing object and the velocity of displacement linearly saw when to carry out horizontal advance on processing object when moving.If adopt vibrating motor to carry out control linear saw in the reciprocating motion of bearing of trend, then to control the matching relationship of linear saw velocity of displacement on an x-y plane that vibrating motor vibration frequency and displacement motor control well.

Preferably, as previously mentioned, linear saw is vertical with machined surface to process processing object.Alternatively, linear saw also can form an angle with machined surface and to process processing object, in this case, if adopt the linear saw with aforementioned clearance structure, then to consider the length of clearance structure, the thickness of processing object and linearly saw the numerical relation of the angle three between the machined surface of processing object, when making the clearance structure of linear saw by processing seam/working groove, linear saw is not clamped by this processing seam/working groove, thus eliminates accumulated error.

More specifically, according to embodiments of the invention, provide a kind of circle mould cutting die board processing device, it comprise bed piece, along the movement of lathe X-direction Combined machining head 300, drive described Combined machining head along the X-axis motor M X of X-direction movement, fixing circle mould cutting die plate 100 turntable 400, drive turntable 400 to carry out the A spindle motor MA rotated along A axle, as shown in Figure 7.Wherein, circular saw and the milling cutter (and/or linearly sawing) of processing circle mould cutting die plate 100 are arranged at Combined machining head 300.Combined machining head 300 can do translational motion along X-axis and Z axis, turntable 400 fixing circle mould cutting die plate 100, thus circle mould cutting die plate 100 is rotated on A axle, by being combined along moving of X-axis and Z axis with the rotation of cutting die plate 100 along A axle by processing head 300, realize the machining control for cutting die plate.As shown in the figure, X-axis is parallel with A axle, and Z axis is vertical with X-axis.Combined machining head 300 can do translational motion based on guide rail along X-axis and Z axis, also can adopt other motion structure.

Preferably, consider motor is driven, synchronous etc. control, described process equipment can be numerically controlled processing equipment.

Fig. 7 a schematically shows the round mould cutting die board processing device of Fig. 7; Fig. 7 b is the enlarged drawing of the processing machine head part of cutting die board processing device shown in Fig. 7 a; Fig. 7 c is the front view of cutting die board processing device shown in Fig. 7 a; Fig. 7 d is the side view of cutting die board processing device shown in Fig. 7 a; Fig. 7 e is the top view of cutting die board processing device shown in Fig. 7 a.Each part of the cutting die board processing device according to the embodiment of the present invention more clearly can be seen from Fig. 7 a ~ 7e.

Fig. 8 a is also the enlarged drawing of the processing machine head part of cutting die board processing device shown in Fig. 7 a, and Fig. 8 a is different from the visual angle of Fig. 7 b.

As shown in Figure 8 a, Combined machining head 300 comprises two groups of circular saw 301a and 301b, and corresponding driving two groups of driver plates saw 301a and 301b carry out motor M 1a and the M1b of High Rotation Speed cutting respectively.Two tool heads, drive motor M 2 and the M3 of two tool heads respectively, and the motor M Z driving Combined machining head 300 itself to move along Z axis.Wherein, circular saw 301a with 301b is mutually vertical along Z-direction, and wherein circular saw 301a is parallel with X-direction, and circular saw 301b is vertical with X-direction.The process equipment with this kind of textural association processing head can complete most of cutwork of the linear pattern cutter seam such as shown in Fig. 1 a, Fig. 1 b fast; And similar aforementioned, the two ends of linear pattern cutter shown in Fig. 1 a, Fig. 1 b seam remain undressed part, the linear pattern cutter seam shown in Fig. 1 c and the seam of the arc-shaped cutter shown in Fig. 1 d, then by milling cutter or linearly saw into processing.

In Fig. 7 a, Fig. 7 b and Fig. 8 a, schematically show only two tool heads, these two tool heads can be the combinations of milling cutter and linear saw, it can be the combination of drilling tool and linear saw, it can be the combination of two milling cutters of different processing dimension, can also be the combination of milling cutter and drawing instrument, etc.

Alternatively, according to the machining tool of the embodiment of the present invention, its Combined machining head 300 also can only include a tool heads, such as, and milling cutter or linearly saw.

Fig. 8 b is the enlarged drawing of an object lesson of the processing machine head part of cutting die board processing device shown in Fig. 7 a.As shown in Figure 8 b, Combined machining head 300 also comprises milling cutter 302 and linear saw 303, drives the motor M 2 of milling cutter High Rotation Speed, drives the reciprocating vibrating motor M3 of linear saw, and the motor driving Combined machining head 300 itself to move along Z axis or cylinder MZ.

As previously mentioned, milling cutter and linear saw both can complete the cutter seam processing to circular saw processing residual fraction, also can process by complete independently cutter seam, just for linear pattern cutter seam, working (machining) efficiency is significantly less than circular saw, thus by circular saw and milling cutter and/or linearly saw the combined tool setting template that can improve on the whole and fill the working (machining) efficiency that cutter stitches.Further, milling cutter and linear saw are functionally identical what stitch processing to the cutter of circular saw processing residual fraction, therefore mutually can replace, that is, Combined machining head only arrange milling cutter or only arranges linear saw.For independent processing cutter seam, linear saw can be higher than milling cutter efficiency, and therefore adopt circular saw to add combination and circular saw, milling cutter and the linear combination of sawing three of linear saw, the Combined machining efficiency adding milling cutter than circular saw can be higher.But, punch operation may be needed owing to utilizing linear saw independent processing cutter seam, thus needing, drilling tool head is set and (at this moment replaces milling cutter with drilling tool head, the combination of composition circular saw, linear saw and boring bar tool) can through the position, hole of linear saw to process on circle mould cutting die plate, but milling cutter itself can serve as drilling tool head, therefore, the combination of circular saw, milling cutter and linear saw three is more practical.

So process equipment according to an embodiment of the invention, can comprise circular saw, three kinds of Combined machining modes of milling cutter or linear saw: (1) circular saw, milling cutter, linearly saw Combined machining; (2) circular saw, milling cutter Combined machining; (3) circular saw, linearly saw Combined machining.

Fig. 9 is the enlarged drawing of the processing machine head part of cutting die board processing device in accordance with another embodiment of the present invention.Different from the structure of the processing head in Fig. 8 a, Fig. 8 b and Fig. 7 b, the processing head in Fig. 9 has only included one group of circular saw 301.Rotate except being provided with the saw blade that can make circular saw 301 thus realizing except the motor M 1 of cutting, also be provided with and can itself rotate (namely by driver plate saw 301, driver plate saw 301 rotating shaft rotate, but not as motor M 1, M1a and M1b, drive saw blade to rotate around the rotating shaft of circular saw) motor M 4.The rotating shaft that circular saw 301 itself rotates can be parallel with Z-direction.

By the angle of ROTATING CIRCULAR SAW 301 itself, the function of the circular saw 301a shown in Fig. 8 a and circular saw 301b can be realized, so the process equipment with this kind of textural association processing head can complete most of cutwork of the linear pattern cutter seam such as shown in Fig. 1 a, Fig. 1 b fast; Similarly, the two ends for the linear pattern cutter seam shown in Fig. 1 a, Fig. 1 b remain the arc-shaped cutter seam shown in the linear pattern cutter seam shown in undressed part, Fig. 1 c and Fig. 1 d, then by milling cutter or linearly saw into processing.

the first Combined machining handpiece structure (two circular saws+milling cutter)

Combined machining head moves under the driving of X-axis motor, the round mould cutting die plate that interlock A spindle motor drives, and makes Combined machining head arrive the round mould cutting die Board position needing processing, and processes;

The linear pattern cutter that Combined machining head stitches the circular saw rapid processing correspondence direction of (such as shown in Fig. 1 a, cutter stitches) equidirectional according to the cutter of cutting die figure seam type selecting one of them and A kind linear pattern cutter stitches, the linear pattern cutter selecting another and B kind linear pattern cutter to stitch the circular saw rapid processing correspondence direction of (such as shown in Fig. 1 b, cutter stitches) equidirectional stitches, thus preprocessing is carried out to A, B two kinds of linear pattern cuttves seams of X-direction and the both direction vertical with X-direction, complete main cutwork;

C kind linear pattern cutter seam (such as the seam of cutter shown in Fig. 1 b) and D kind arc line type cutter seam (such as the seam of cutter shown in Fig. 1 b) on milling cutter processing circle mould cutting die plate, realize the cutter seam processing to C kind linear pattern cutter seam and D kind arc line type;

Circular saw, after processing A, B two kinds of linear pattern cutter seams, can remain undressed part at the two ends of A, B two kinds of linear pattern cutter seams, and milling cutter supplements this residual undressed part of machining.

Optionally, for needing to process fixed hole position on circle mould cutting die plate, milling cutter can be selected.Milling cutter cutting processing can go out the fixed hole position of dead knife template on circle mould cutting die plate.

Optionally, for the synchronous connecting shaft in order to deduct in the middle of turntable two ends, reduce the weight of complete machine, turntable drives by two groups of A spindle motors are synchronous two the synchronous rotary realizing turntable two ends fixed disc and circle mould cutting die plate, has deducted the fixed connection shaft being used for transmission rotary driving force in the middle of turntable two ends.

Optionally, for needing to draw cutting die figure on circular arc cutting die plate, drawing instrument head links the round mould cutting die plate that A spindle motor drives under the driving of X-axis motor, and circle template is drawn out required cutting die figure.

Optionally, for outfit tool replacing apparatus and tool storage room, tool replacing apparatus arrives tool storage room position under the driving of X-axis motor, capture respectively and change circular saw, milling cutter, drawing instrument and other alternative instruments, the round mould cutting die plate that the A spindle motor that links under the driving of X-axis motor drives, circle mould cutting die plate is processed accordingly.

Particularly, the longer linear pattern cutter parallel with vertical with X-axis is stitched (namely A, B kind linear pattern cutter stitches), circle mould cutting die board processing device automatic selector disc saw carries out quick preprocessing, undressed part residual after preprocessing, comprise subtriangular part and/or non-penetrating component (see Fig. 2 e), milling cutter supplementary processing selected automatically by process equipment.That is: the position that the longer linear pattern cutter that the round mould cutting die plate that Combined machining head drives circular saw to link the driving of A spindle motor under the driving of X-axis motor moves to needs processing stitches; Circular saw starts, and carries out preprocessing to the linear pattern cutter seam that need process, and most linear pattern cutter seam cutwork is completed at a high speed, only the undressed part at residual cutter seam two ends.For shorter linear pattern cutter seam, the undressed part of the residual arc of processing; Circular saw instrument exits Working position; After Combined machining head drive milling cutter to link under the driving of X-axis motor round mould cutting die plate that A spindle motor drives moves to circular saw processing, residual undressed part is or/and shorter linear pattern cutter seam processing remains the undressed portion of arc; Linearly the undressed part that remains of type cutter seam machining path processing linear type cutter seam two ends is or/and the undressed part of the shorter residual arc of linear pattern cutter seam processing for milling cutter, until linear pattern cutter stitches whole completion of processing, milling cutter exits Working position; Combined machining head exits Working position, whole linear pattern cutter seam completion of processing.

The linear pattern cutter parallel or not vertical with X-axis for angle stitches, i.e. C kind linear pattern cutter seam, and circle mould cutting die plate numerically controlled processing equipment selects milling cutter to machine automatically.

For shorter linear pattern cutter seam, the length of its cutter seam is less than the diameter of circular saw, then circular saw may not be cut and wear round mould cutting die plate, can remain the undressed part of arc, then utilize milling cutter or linear saw to process.Circle mould cutting die plate numerically controlled processing equipment also can select milling cutter to machine automatically.

For arc line type cutter seam, circle mould cutting die plate numerically controlled processing equipment selects milling cutter to process automatically.That is: Combined machining head drive milling cutter link under the driving of X-axis motor A spindle motor drive round mould cutting die plate move to arc line type cutter stitch Working position; Milling cutter is along arc line type cutter seam machining path processing arc line type cutter seam, until arc line type cutter stitches whole completion of processing, milling cutter exits Working position; Combined machining head exits Working position, whole arc line type cutter seam completion of processing.

For closed line style cutter seam, the machining starting point stitched due to closed line style cutter and terminal overlap, and the line style that during processing closed line style cutter seam, round mould cutting die plate numerically controlled processing equipment stitches according to closo cutter, selects corresponding circular saw or milling cutter to process automatically.

For obtuse angle, wedge angle or right angle etc. turn round line style cutter seam, because the line style cutter seam that turns round can be considered as by the linear combination that two line style cuttves stitch and a turning forms, the line style that circle mould cutting die plate numerically controlled processing equipment stitches according to two line style cuttves, selects corresponding circular saw or milling cutter to process automatically.Turning is then processed by milling cutter.

For band gap bridge bit line type cutter seam, stitching actual owing to being with gap bridge bit line type cutter is one section of line style cutter seam is separated into two sections of line style cuttves seams process, one section of technique of not processing spaced intermediate, therefore adds and can process by the technique of processing two sections of line style cutter seams respectively man-hour.The length that circle mould cutting die plate numerically controlled processing equipment stitches according to line style cutter and whether be straight line and automatically select milling cutter or circular saw to process respectively.Some bridge locations are half bridge location, and the degree of depth of half bridge location and cutter seam is less than the thickness of round mould cutting die plate, and the cutter seam of this part does not cut to wear round mould cutting die plate.For the situation of half bridge location, milling cutter can be selected to process.

In addition, when processed round mould cutting die plate cutter seam is all arc line type cutter seam, milling cutter can only be used to process.In practice, this type of circle mould cutter template number is considerably less.

When processed round mould cutting die plate cutter seam is all linear pattern cutter seam, circular saw and milling cutter Combined machining must be used.First can carry out preprocessing with circular saw to longer linear pattern cutter seam, the processing operation of high speed accomplish linear type cutter seam, residual undressed part after circular saw processing and shorter linear pattern cutter seam are then completed with milling cutter supplementary processing.The use of circular saw significantly can improve the working (machining) efficiency of linear pattern cutter seam.
