Description

Three-D puzzles
The present invention relates to a kind of assembly evil spirit (puzzle), specifically, relevant with three-D puzzles.So-called three-D puzzles is meant and comprises many pieces, can be assembled into the three-dimensional block toy of an integral body.
There is a kind of cydariform to piece together evil spirit in the known three-D puzzles, forms by a series of pieces.These pieces are made the mutual inlaid shapes that one of them clamping block of last usefulness locks together all pieces.The shortcoming of the assembly evil spirit of a clamping block of this use is that in case pull down this clamping block, remaining piece just all can scatter.This is because these pieces do not resemble jigsaw that two dimension pieces together evil spirit mutual can locking together, can not interlocking and just make mutual concavo-convex complementary shape, so need each piece be locked together with a clamping block.
This assembly evil spirit has remove the shortcoming that clamping block will cause each piece to scatter after assembly unit is good.Similar, when the assembly unit piece,, be difficult to sometimes these pieces are kept together because the good piece of part assembly unit can move and rotate.
In order to overcome these shortcomings of existing three-D puzzles, generally, three-D puzzles proposed by the invention comprises one group of three-dimensional assort that is entrenched togather, and this spelling spare comprises:
Rely on the first and second chimeric assorts of the first and second chimeric surfaces,, just define one the 3rd chimeric surface if these two assorts are chimeric in the tram; And
The 3rd assort with one the 4th chimeric surface, the 3rd assort is chimeric by chimeric and first and second assorts on the third and fourth chimeric surface;
In this three-D puzzles, after first, second and the 3rd assort are entrenched togather,, just can not take first and second assorts apart if earlier the 3rd assort is not pulled down.
First and second assorts are preferably by chimeric in addition along moving of one or two axle.Can adopt a kind of simple tenon groove structure, make piece can along the longitudinal sliding motion of tenon groove structure or with this vertically vertical direction on move.Tenon groove structure is recess-type preferably also, make chimeric can only be by carrying out along longitudinal axis slip piece.
Can utilize similar chimeric surface that the 3rd assort and first and second assorts are linked together.
Some or all assorts can be many pieces assorts.Those pieces of each many pieces assort can just be abutted against, and also can be the interlockings with one or two free degree.Forming on each piece of best this assort is surface of certain chimeric surface part, makes that these pieces are no longer loosening after this assort and another assort are chimeric.
Under the situation that adopts the concave type tenon groove structure that assort or piece are entrenched togather, tenon and groove can be splayed.Like this, can only be chimeric by carrying out in the slip of a direction, rather than both direction can.
The invention allows for a kind of equipment of hot line cutting thermoplastic material.Put it briefly, this device comprises:
A conductor wire that is pulled between 2;
Drive unit at the conductor wire of length direction pulling between these 2; And
One with voltage at these 2 pressue devices that are added on the conductor wire.
The voltage that is added on the conductor wire can change, to adapt to the interval between 2 and the kind of the material that must cut.Equally, pulling force and conductor wire speed also can be adjusted according to material.
Conductor wire can be a continuous ring, also can be a single line of moving take-up reel from the confession drum to.When conductor wire all draws when being rolled onto take-up reel, these two dishes can be exchanged, and former take-up reel is become for drum.
This equipment can be portable, is moving cutting material.Perhaps, can fix, and mobile material cuts.If fixing equipment, the operating desk of the material that a placement will cut is preferably arranged, and conductor wire passes this operating desk pulling.Angle between conductor wire and the operating desk can be constant, also can be variable.If constant, preferably conductor wire is vertical with operating desk.

As seen from Figure 1, the profile of three-D puzzles 10 is squares.Piece together evil spirit 10 six assort pieces 12,13,14,15,16 and 17 are arranged.
These six pieces can be regarded as three couples of 12+13,14+15 and 16+17, and this will be described below.Yet pairing is recommendatory like this, and in other forms of the present invention, the assort piece can be a non-matching.
Assort piece 12 has parallel outer face 20 and 21, and vertical side 22, the part outer surface of the square 10 that these several formation are assembled into.Piece 12 also has inner surface 24,25 and 26.Inner surface 24 extends between end face 20 and 21, and inner surface 25 and 26 extends between side 22 and the inner surface 24.
Surface 24 defines the groove 28 of the longitudinal extension of a constant cross-section.Yet if necessary, this cross section also can longitudinally reduce gradually.Groove 28 has the cross section of T shape, basically with end face 20,21 vertical extensions.Yet this is not to be substantial, groove 28 can with end face 20,21 one-tenth any desirable angles.
Inner surface 25 defines tenon 29a, the 30a of two longitudinal extensions, and the cross section of these two tenons all is constant.Yet also can be longitudinally to go up gradually to reduce, but these two tenons must be along being tapered on the identical direction.Each tenon all has the cross section of T shape, all basically with side 22 vertical extensions.If necessary, tenon 29a, 30a can with the 20 one-tenth any angles in side, but must keep being parallel to each other.Can only form a tenon, two is not to be substantial.
Similar, inner surface 26 also defines tenon 31a, the 32a of two longitudinal extensions, and each all has constant T shape cross section.Tenon 31a, 32a all basically with side 22 vertical extensions, yet also be can be and the 22 one-tenth any angles in side.Tenon 31a, 32a need not be parallel with tenon 29a, 30a, and it is constant that cross section also needs not to be.
Though tenon 29a to 32a has constant cross section, if necessary, these tenons can longitudinally change shape.Yet each must change shape along identical direction to two tenons in the tenon.
Assort piece 13 has parallel outer face 40,41 and vertical side 42.The orientation of end face 40,41 and spacing must be with the end face 20,21 of assort piece 12 identical.Like this, form two even curfaces respectively having spliced rear end face 20 and 40 and 21 and 41.Piece 13 also has inner surface 44,45 and 46.Inner surface 44 extends between the end face 40,41, and inner surface 45,46 extends between inner surface 44 and the side 42.
Surface 44 is complementary with surface 24 on the piece 12, thereby defines a vertical T shape tenon 48, but its size is just in time in the embedded groove 28.Therefore, piece 12 and 13 can be stitched together by tenon 48 is slipped into groove 28 from longitudinally, as shown in fig. 1.If the cross section of tenon 48 and groove 28 is not constant, can only these two pieces be stitched together from a direction so.
Inner surface 45 configurations are identical with the surface 25 of piece 12, define the tenon 29b and the 30b of two parallel T shape longitudinal extensions.The shape on surface 45 is made in rear surface 25 and 45 that piece 12 and 13 is stitched together and is formed a single continuous surface.Specifically, tenon 29a and 29b aim at, and become single tenon 29; And tenon 30a and 30b aim at, and become single tenon 30.
Similar, inner surface 46 configurations are identical with surface 26, define tenon 31b and 32b.After piece 12 and 13 splicings, tenon 31b and 32b aim at tenon 31a and 32a respectively, form tenon 31 and 32.
Assort piece 15 has parallel outer face 60 and 61, vertical side 62 and end face 63.Inner surface 64 extends between end face 60 and 61, and inner surface 65 extends to inner surface 64 from end face.
Inner surface 64 is complementary with the surface 25 and 45 that is on piece 12 and 13 respectively.Therefore, inner surface 64 defines two groove 66a and 67b that admit tenon 29 and 30 respectively.
Surface 65 is not the plane, defines tenon 68 and groove 69 of a projection.Surface 65 configuration and with end face 60 and 61 angulations all can be random.
Piece 14 also has parallel outer face 70 and 71, side 72 and end face 73.Inner surface 74 extends between end face 70 and 71, and inner surface 72 extends to inner surface 74 from end face 73.Inner surface 74 is with surface 65 complementations of piece 15, but therefore defines the tenon 78 of embedded groove 69 of a projection and the groove 79 of a receivability tenon 68.In this embodiment of Fig. 1, surface 75 is processed into and these two pieces can be stitched together by moving on the direction that stacks the vertical end face 63 in back and 75 with end face 60 and 70 adjacent modes with 65 shape.Yet,, must push with longitudinally so and could splice this two pieces from tongue-and-groove if concave type all is processed on these two surfaces.Which kind of all can adopt these two kinds of surface configurations.But the surface configuration of concave type needs careful mounting or dismounting, is difficult for scattering after the piece splicing.
Assort piece 16 and 17 and piece 14 and 15 similar, have respectively and inner surface 80 and 81, all with the surface 26 and 46 complementations.As piece 14 and 15, piece 16 and 17 relies on the inner surface 84 and 85 that limits complementary tenon, groove to be stitched together.Shown in this situation, the splicing of these two pieces need not slided on the longitudinally of tenon, groove.
As can be seen, also can adopt other shapes for the chimeric surface of piece 14,15,16 and 17.
This pieces together evil spirit for assembly unit, at first piece 12 and 13, piece 14 and 15, piece 16 and 17 must be stitched together by corresponding tenon is embedded in the corresponding groove respectively.
Then, can be with the piece 14 that is stitched together and 15 chimeric with the piece 12 and 13 that is stitched together by the slip (shown in arrow 90) that is parallel to tenon 29 and 30.Equally, can be with the piece 16 that is stitched together and 17 chimeric with the piece 12 and 13 that is stitched together by the slip (shown in arrow 91) that is parallel to tenon 31 and 32.
Can see, at first can not good this assembly evil spirit of assembly unit with this several piece is stitched together.For example, 15 independent cunnings are not embedded on the piece 15 if piece 14 is not with piece, just can not put in place when being embedded into piece 15 cunnings on the piece 12 so, because can not fit in surface 65 and 75.Equally also can see, only remove piece 14 to 17, just can and open in 13 minutes piece 12.This be because piece 12 and 13 chimeric surperficial 24 and 44 with piece 14 and 15 on surface 65 and 70 and with piece 16 and 17 on surface 84 and 85 also misalignment, but stagger.If aim at by the line of cut that these surfaces form, piece 12,15 is moved relative to piece 13,14 and 17 on direction shown in the arrow 92 together with 16.This discontinuity in these lines of cut of each piece represents that certain piece or piece just can pull down another piece to after must pulling down just.
If necessary, composition surface 65 and 75 can all be flat surface, and piece 14 and 15 just can be pulled down from piece 12 and 13 independently like this.This can not influence assembly unit, and this pieces together the steadiness of evil spirit, as long as piece 14 or 15 also has one to be entrenched togather with piece 12 and 13.Therefore, for example pull down and piece 15 is stayed under the situation of original position at piece 14, no matter whether piece 16 and 17 is pulled down, and piece 12 and 13 still can be locked in original position by chimeric with it piece 15.Piece 14 is stayed original position if piece 15 is pulled down, and so just piece 12 and 13 can not be pulled down together, because piece 16 and 17 stops the motion of piece 13 relative piece 12 on direction shown in the arrow 92.
Fig. 3 and 4 shows the square 100 that constitutes according to the present invention.Square 100 comprises piece 102 to 107, and each is a flat square basically. Piece 102 and 103 is the pairing pieces in inside, and piece 104 to 107 is non-matching pieces externally.
Piece 102 and 103 has chimeric surperficial 110 and 112 of complementation respectively.Surface 110 defines a vertical T shape tenon 114, is embedded in vertical T-slot 116 of surperficial 112 complementations that limit.
Piece 102 and 103 upper surface 118a and 118b separately is the plane basically, has T-slot 122a and 122b respectively. Piece 102 and 103 chimeric after, surperficial 118a and 118b just define a single plane surface 118, have a single groove 122 that passes this surface.Certainly, the surface 118 with groove 122 can with 124 one-tenth any angles of sidewall.
Similar surfaces 118a and 118b, piece 102 and 103 lower surface 126a and 126b separately has T-slot 127a and 127b respectively, forms a single groove 127 at piece 102 and 103 chimeric backs.
Piece 102 has a surface 126, is substantially perpendicular to sidewall 124a and upper surface 118a and extends, but needn't leave no choice but like this.This surface 126 defines T-slot 128a and the 128b that two parallel longitudinal directions extend.These two grooves and sidewall 124a extend in parallel, but also can become any angle.
Piece 103 has a surface 130, is substantially perpendicular to sidewall 124b and upper surface 118b and extends.There is the parallel T shape tenon 132a and the 132b of two projectioies on this surface 130, is substantially perpendicular to surperficial 118b and extends.Equally, surface 130 also can be into any angle extension with tenon 132a, 132b.
Piece 104 is one flat substantially, and an inner surface 140 is arranged.That extends on inner surface 140 has two parallel T shape tenon 141a and 141b, respectively with surface 126 on groove 128a and 128b complementation.Tenon 141a and 141b from the lower edge 142 beginnings 140 extended one section on the surface, up to upper surface 143a, the 143b of these two tenons respectively with the upper surface 118a and the 118b coplane of piece 102 and 103.
The inner surface 150 of piece 105 has a single tenon 151 with groove 127 complementations.This tenon 151 has extended one section from a left side along 152 beginnings on surface 150, and end face is on the surface 140 that just in time is attached to piece 104 after the assembly unit.
The lower surface 160 of piece 106 has a T shape tenon 161, has crossed over the whole width on surface 160.Tenon 161 and groove 122 complementations, after assembly unit along 162 planar sections that just in time are attached to surface 140.
At last, piece 107 also is one flat basically, and an inner surface 170 and a upper surface 171 are arranged.Upper surface 171 have after the assembly unit with piece 102,103 on the continuous groove 122c of groove 122a, 122b.The tenon 161 of piece 106 is also in the embedded groove 122c.
Inner surface 171 has two parallel T-slot 172a and 172b, respectively with T shape tenon 132a and 132b complementation.Piece 107 extends downwardly into and exceeds piece 103, so groove 172a and 172b not necessarily leave no choice but pass surface 170, if necessary, these two grooves can reach till lower surface 126 edges.
This pieces together evil spirit for assembly unit, at first connects piece 102 and 103 in the groove 116 by tenon 114 is slipped into.Then by tenon 151 being slipped in the groove 127, tenon 132a and 132b being slipped in groove 172a and the 172b, respectively with piece 105 and 107 and the piece 102 and 103 assembly units that are stitched together. Piece 105 and 107 assembly unit order can be opposite, because these two pieces are not chimeric mutually.Certainly, if tenon 151 extends to left in the groove of a complementation of piece 107, piece 107 just must be before piece 105 assembly unit good.
Then, assembly unit piece 104 and 106.Though these two pieces are not chimeric mutually, the assembly unit order can not be opposite.Piece 104 must be on piece 106 be pre-installed, put in place, otherwise piece 106 will block tenon 141a and 141b, and these two tenons can not be entered in groove 128a and the 128b.Identical with the situation of piece 105 and 107, if necessary, piece 104 and 106 also can be processed into chimeric mutually.
This cubical unpack procedure is just in time opposite with the assembly unit process.
By above-mentioned explanation as seen owing to processed tenon and groove on the surface in splicing, the therefore situation that when assembly unit, can not occur scattering, that is to say must be successively one by one with piece from pulling down with its one or several chimeric piece.In addition, after pulling down one or several piece, all the other pieces will still remain on original position.
Fig. 5 to 19 shows the spheroid 300 that constitutes according to the present invention.Spheroid 300 comprises a series of assorts 310 to 326, respectively is shown in Figure 10 to 12 and Figure 14 to 19.
Assort 310,312 and 314 is entrenched togather and forms a core body 306, shown in Fig. 5 to 9.Assort 316 to 326 is fitted on the core body 306 then, is assembled into this complete spheroid 300.
As seen from Figure 10, assort 310 has first cannelure 330 and second cannelure 332 along second extension along first extension in its surface.These two grooves 330,332 are vertical mutually basically to be extended.Groove 330,332 all is the T-slot of indent, thus the tenon that matches of shape and this groove can only from corresponding vertically slip into chimeric.Though assort 310 is core body assorts, still have a surface 400, be the part of the outer surface of spheroid 300.
Assort 310 is cut into two piece 311a, 311b by line of cut 334.Line of cut 334 can be any route by this assort, as long as piece separately and again can be spliced.It should be noted that line of cut 334 is by groove 330, in the time of therefore in a tenon embedded groove 330 is arranged, piece 311a and 311b just can not separate.
Similar, assort 312 has one first groove 340 and one second groove 342 (can see more clearly) in Fig. 5, and trend becomes 90 ° mutually substantially.Line of cut 344 is divided into piece 313a and 313b with assort 312.Line of cut 344 has only by opposed slot 340 and angle of 342 rotations and piece 313a and 313b branch could be opened by groove 340 and 342.Therefore, when having a corresponding tenon to be embedded in groove 340 or 342, these two pieces just are locked in together.
Assort 312 also has the extension 354a of a part of a formation tenon 354 and the surface 402 and 404 that forms the part outer surface of spheroid 300.
Assort 314 has a horizontal tenon 350 that extends along a side and a vertical tenon 352 that extends along offside (can referring to Fig. 5).Two horizontal tenons 354 and 356 extend along upside and downside respectively, and are parallel with tenon 3 basically and be parallel to each other, but also can extend along different directions.Assort 314 is divided into piece 315a and 315b by line of cut 360.Line of cut 360 is by tenon 350, and as shown in figure 12, in the time of therefore in tenon 350 or 352 is embedded in a complementary groove, piece 315a and 315b just are locked in together.
This assort has surface 406,408 and 410 on tenon 356 and 354, form the part outer surface of spheroid 300 respectively.
Tenon 350 on the assort 318 is complementary mutually with groove 332 on the assort 310, therefore just can make assort 314 and 310 chimeric mutually by tenon 350 being slipped in the groove 332, thereby with piece 311a and 311b locks together and piece 315a and 315b are locked together.
Tenon 352 on the assort 314 is complementary with the groove 342 on the assort 312.Therefore, just can make assort 312 and 314 chimeric by tenon 352 vertically being slipped in the groove 342, thereby piece 313a and 313b are locked together.After in place like this, extension 354a just becomes the part of tenon 354.
As seen from Figure 5, assort 310,312,314 these three be bolted together after, also formed in addition two grooves 362 and 364.These two grooves also all are concave shaped.
By Figure 14 to 19 as seen, assort 316,320 and 324 is similarly substantially, each has 370,372,374 and interior tenons 380,382,384 of an outer surface.Outer surface 380,382,384 forms the part outer surface of spheroids 300, and the size of each tenon respectively with three core body assorts 310,312,314 on corresponding groove corresponding.
Assort 318 also has an outer surface 376 and an interior tenon 386.It also has one second tenon 354c, roughly with tenon 386 vertical extensions.
Assort 322 and 326 is similar, has 378,379 and inside grooves 390,392 of an outer surface separately.Assort 326 also has one second groove 330a, roughly with groove 392 vertical extensions.
Groove 390 and tenon 356 complementations on the assort 322 can be chimeric.After assembly unit puts in place, assort 322 will stop the downward motion of assort 312, but not stop motion upwards, because assort 322 and 312 is not interlocking.
The tenon 386 and the groove 362 of assort 318 are complementary, therefore can slip in the groove 362, make tenon 354c aim at the tenon 354 on the assort 314.So just assort 310 is locked on the assort 314, because assort 310 and 314 horizontal movement each other has been subjected to obstruction.In addition, because it has covered assort 322, thereby stoped towards the horizontal movement of assort 318.
Tenon 382 on the assort 320 is complementary with groove 364, therefore can slip in place, thereby extension 354b aims at tenon 354.Assort 320 has also covered assort 322, thereby has stoped its motion towards assort 320.Therefore, after assort 318 and 320 all put in place, assort 322 was just locked on the position.
Groove 392 on the assort 326 and extension 354a, b, the c on tenon 354 and the assort 312,318,320 are complementary.Assort 326 can be slipped into by horizontal movement in place, chimeric with assort 312,314,318,320.So just assort 312 and 314 is locked together, stoped the opposing vertical motion in the groove 392 because extension 354a is embedded in.Similar, assort 318 and 320 is because extension 354b, 354c and groove 392 are entrenched on the position also locked.
After putting in place, groove 330a aims at the groove 330 on the assort 310.
Tenon 384 on the assort 324 is complementary with groove 330,330a on the assort 310,326, therefore assort 324 can be slipped in placely, locks in the position and to decide assort 326.
At last, can make assort 316 and more corresponding assorts chimeric by tenon 380 being slipped in the groove 34 on the assort 312.
The magic available heat foamed plastic of assembly of the present invention is made by hot line cutting equipment cutting forming.With the hot line cutting, produced each assembly evil spirit will be unique.If it is identical requiring a collection of assembly evil spirit, each assort can be made respectively so, for example adopts blowing or molding process.Certainly, piecing together evil spirit can use other materials (as timber) and additive method (as laser cutting) to make.The invention allows for a kind of equipment with hot line cutting foamed plastics, this is a kind of method of making above-mentioned assembly evil spirit.Figure 20 and 21 shows the schematic diagram of this cutting equipment 200.Cutting equipment 200 has the operating desk 202 of a level, and workpiece just is placed on this operating desk and processes.
An aperture 204 is arranged on the operating desk 202, and metal wire 206 passes this aperture and walks about.Metal wire 206 is gone to the take-up reel 210 that is installed in operating desk 202 belows from the drum 208 that supplies that is installed in operating desk 202 tops.
Operating desk 202 and take-up reel 210 are fixedly mounted on the unshowned machine frame.Be installed on the support 212 of operating desk 202 liftings relatively for drum 208, to be fit to the foamed plastics spare of cutting differing heights.
Metal wire 206 is from essentially horizontally moving top sheave 214 to for drum 208.Top sheave 214 is installed on the support arm 216 that is connected with support 212.Therefore, top sheave 214 can be along with moving both vertically together for drum 208.
Top sheave 214 is positioned to make metal wire 206 to pass hole 204 vertically downward and moves on the lower sheave 218 that is fixed on the machine frame.Metal wire 206 is walked around pulley 218, is moved take-up reel 210 to by cleaner 220.Take-up reel 210 is driven by the variable motor 211 of rotating speed, makes that metal wire 206 can be from being rolled onto on the take-up reel 210 for drum 208.The rotating speed of motor is by controller 213 controls.Be installed on the threaded axle 222 in that vertically stretch out, upper end for drum 208.Spring 224 and threaded adjuster 226 also are housed on axle 222, and spring 224 is installed in between drum 208 and the adjuster 226.When spring 224 between drum 208 and the adjuster 226 by compression the time, just play a part to hinder for drum 208 and rotate.Therefore, be added in pressure on the spring 224 by change and just can change metal wire 206 tension force the metal wire 206 when pulling out for drum 208.Certainly, also can adopt other the mode that applies tension force.
Pulley 214 and 218 all is to use conductive material, and for example brass is made, with machine frame and support arm 216 electric insulations.Equally, also insulate for drum 208 and take-up reel 210 with machine frame and support 212.Therefore, the electric pathway between two pulleys 208 and 210 have only by the metal wire that between these two pulleys, moves 206 this.
This equipment is equipped with a controller 230, and voltage is added between pulley 208 and 210, makes electric current flow through metal wire 206.Metal wire 206 is that the diameter of Japanese Ishibarhi production is the stainless steel wire about 0.15mm.Spacing between the pulley 214 and 218 is variable between 10 to 20cm.For such spacing, the voltage about 20 volts can make metal wire be heated to about 300 ℃.Along with the increase of pulley room distance, the resistance and the surface area of metal wire all increase, and therefore require voltage higher, could guarantee that like this temperature is certain.
In use, adjust support 212, making has enough distances between operating desk 202 and top sheave 214 for the workpiece that will cut.Motor speed is adjusted according to the thickness and the density of the workpiece that will cut, and makes the speed of metal wire increase along with the increase of thickness and foamed plastics density.Having found that, is that 5-10 centimetre, density are every cubic metre 90 foamed plastics to 120 kg for thickness, and the speed of metal wire is pretty good in 2 to 4 meter per second effects.If linear speed is too low, the foamed plastics of thawing is bonded on the metal wire 206, and cutting will be inhomogeneous, and Tai Gao can cause cutting excessively.
It also is adjustable being added in two voltages between the pulley, and purpose is to keep the metal wire temperature constant substantially.Therefore, voltage should increase along with the increase of the rotating speed of the spacing between the pulley, the thickness of foamed plastics that needs cutting and density, motor.Voltage also needs the type change according to the foamed plastics of need cutting, because different foamed plastics melting points is also different.For example, the melting point of polystyrene foam plastics is different from the melting point of the various foamed plastics that polyethylene makes.
Best, Control of Voltage can be by carrying out the metal wire temperature from the mode that temperature sensor 232 feeds back to controller 230 automatically, remains unchanged substantially after making the metal wire temperature set, and therefore only needs to set temperature required getting final product.The temperature of metal wire should be with the fusing foamed plastics, but not high counter the adhering on the foamed plastics that becomes flowability to the material that makes fusing.Preferably the material of all fusings can all adhere on the metal wire.Be appreciated that the plastics that cut there is no sharp melting point in fact, but in certain temperature range, become liquid from solid.
Set each necessary control back cabling, promoted foamed plastics and cut facing to metal wire 206.The temperature of metal wire makes the foamed plastics fusing, forms line of cut.Because metal wire is in motion, the foamed plastics of tip-off is bonded on the metal wire to be taken away, and therefore can not make the line of cut distortion, thereby can obtain clean line of cut.Waste material is bonded on the metal wire 206, takes cleaner 220 to.Cleaner 220 can be exactly a groove or a liner that is immersed in this solvent of adorning the solvent that can dissolve the foamed plastics that is cut.Perhaps, can scrape off the waste residue that is bonded on the metal wire 206 with the scraping of a machinery.In case metal wire 206 entirely from being rolled onto on the take-up reel 210 for drum 208, only needs these two dishes are exchanged, threading gets final product again.
Corresponding with two drums of above-mentioned usefulness, also can replace with a continuous metal wire loop.The metal wire loop is loaded on each pulley, and situation and a band shape saw are similar.
The present invention proposes a kind of assembly evil spirit of novelty and a kind ofly be used for cutting thermoplastic material, particularly make this equipment of piecing together magic material.
