Below, do to specify with regard to the suitable example of powder rolling screw-threads forming machine 10.

1. metal pattern heating part

(1) hot blast blows out portion

Be used for the structure that the hot blast of the metal pattern of heating of metal mould heating part directly blows out portion and there is no special restriction.For example, shown in Fig. 3 (a), it is constructed preferably: the hot blast that obtains by hot air generator (figure slightly), supply with fan 46 via the air of below that is located at hot air blow port 16 or downside, supply with hot air blow port 16 through main pipe arrangement 43.Promptly, it is constructed preferably: the hot blast that obtains by hot air generator, with the hot blast that reclaims, sends into mixing chamber 44 by energy recoverer 24 in the stove through air circulation fan 42, after in mixing chamber 44, suitably mixing, by air supply fan 46 a large amount of hot blast with regulation wind speed is supplied with hot blast by main pipe arrangement 43 and blow out portion 16.

Its reason is: by adopting such structure, in the heating mode about the metal pattern in the heating furnace 28 12, when hot blast 14 flowed at the inner surface along metal pattern 12, hot blast 14 heat of being with can conduct to metal pattern 12.That is to say,, in the heat of supplying with heating furnace 28 inside, can tail off owing to heat conduction is dispersed into heating furnace 28 outer heats as main conduction mode.Therefore, even heating furnace 28 is small-sized with hot blast generation EGR 40, compare the production capacity more than also having on an equal basis with Large-scale Heater in the past.In addition,, mixes with the hot blast of the hot air generator of supplying with from hot air blow port 16 (figure is slightly) by the hot blast that reclaims in the stove via energy recoverer 24, pressurized because of air quantity increases, heating furnace 28 is interior etc., so increased the thermal effect that adds to metal pattern 12.Further, with energy recoverer 24 be located at heating furnace 28 around or the below, because of the relation and the heating furnace 28 of air quantity are compared, because of being in decompression state, so can more effectively reclaim the hot blast behind the heating of metal mould 12.

In addition, when preferably staying the hot blast storage chamber 39 to be located at the centre of main pipe arrangement 43, the exit portion of the main pipe arrangement 43 among chamber 39 is stayed in the hot blast storage is provided with baffle plate 49.

Its reason is: by adopting such structure, can enough baffle plates 49 make and supply with the fan 46 hot blast branches of sending into by air and dissipate, even under the situation that a plurality of hot air blow port 16 is set, also can make it blow out hot blast equably from separately hot air blow port.

In addition, for under controlled state, hot blast be can blow out, preferably the shape that blows out the peristome of portion at this hot blast circle, ellipse, quadrangle, (containing square or rectangular, strip etc.), polygon, random shape are made as with certain wind speed.

In addition, about the quantity of hot air blow port, as Fig. 3 (a) and (b), preferably more than one or one.For example, shown in Fig. 3 (a), even when the quantity of hot air blow port 16 substantially is set as one, by energy recoverer 24 suitably is set, even also can heat efficiently than relatively large metal pattern.In addition, shown in Fig. 3 (b), by the quantity of hot air blow port 16 substantially is made as more than two, even a plurality of metal patterns simultaneously, under the different state of heating condition, also can heat efficiently.

(2) energy recoverer

The energy recoverer preferably is set, to be used to reclaim the hot blast (heat energy) that still is in a large amount of high energy of high temperature behind the heating of metal mould.That is, shown in Fig. 3 (a), preferably utilize the stove inner bottom surface 18 of heating furnace 28 or heating furnace 28 around, set energy recoverer 24.

At this, the structure of energy recoverer 24 itself there is no particular restriction.For example, shown in Fig. 3 (a), when preferably having the peristome of the stove inner bottom surface 18 that leads to heating furnace 28, have the pipe configuration that is connected the branch's pipe arrangement 47 on the hot blast generation EGR 40.And as mentioned above, the centre that is preferably in the branch's pipe arrangement 47 that is connected on the energy recoverer 24 sets baffle plate 47a.

In addition, be provided in the energy recoverer 24 of the stove inner bottom surface 18 of heating furnace 28, as Fig. 4 (a) and the peristome (b), preferably along the bight or the edge setting of stove inner bottom surface 18.

Its reason is, because in metal pattern 12, inner surface along this metal pattern 12, become easy from hot air blow port 16 to the mobile of hot blast 14 that energy recoverer 24 moves, so the time of staying becomes longer, its result is that each corner in the metal pattern 12 can both be heated with this conduction mode by hot blast 14 effectively.In addition, because the wind speed of hot blast 14 is fast, can prevent effectively that the conduction mode thermal diffusion is obstructed.

In addition, shown in Fig. 4 (b), preferably the shape with the peristome of energy recoverer substantially is designed to " V " font or " コ " font.

Its reason is, the hot blast 14 that is blown out by hot air blow port 16 easily and promptly moves to the energy recoverer 24 of regulation shape, during this period, produces the hot blast stream of appropriateness, can heat effectively metal pattern 12.

In addition, the shape about the peristome of energy recoverer 24 can be combined into the shape shown in Fig. 4 (a) and Fig. 4 (b), even but in this case, also preferably can be designed to the easier structure that generates the hot blast stream of appropriateness.For example, shown in Fig. 4 (a), decide under the state in space substantial covering the in top of tetragonal energy recoverer (auxiliary recoverer) 24 being provided with.After comparatively ideal energy recoverer (main recoverer) by " V " font shown in Fig. 4 (b) or " コ " font reclaims heat energy, utilize institute decide the space, from the final recovery heat energy of the tetragonal energy recoverer as 4 (a) shown in (assisting recoverer) 24.

In addition, metal pattern 12 as Figure 10 (a) and (b), preferably with the frame section 13 of metal pattern 12 and the blank area of forming face 85, is for example done water-proofing treatment with sealing material 87.Its reason is by adopting such structure, in the metal pattern refrigerating work procedure, can prevent on the surface of excess moisture ground attached to tablet.Therefore, in surface treatment procedure, for example, the formation of the surface-treated layer of handling through the silicic acid flame becomes easy.

In addition, this metal pattern 12 is preferably following structure: frame section material 13 is fastened or is suspended in (scheme slightly) to come moving metal mould 12 on the robot arm, for example, in the metal pattern heating part, with robot arm frame section material 13 is moved on to the upper end, from the peristome that is arranged on the upper end metal pattern 12 is moved into heating furnace 28 again.By such structure, the conveyance of metal pattern becomes and is easy to simultaneously, and the configuration of each component part of powder rolling screw-threads forming machine etc. has also become easily.

And the heat-insulating material of sealing effectiveness (figure slightly) is preferably wrapped on the surface of metal pattern support portion material.For example, the combination with copper silicon rubber/fluoride resin film covers.Its reason is, the space with metal pattern support portion material is sealed 18 of metal pattern 12 and stove inner bottom surfaces can prevent efficiently that hot blast from escaping into the outside.And, metal pattern support portion material preferably has regulative mechanism, to regulate the position of putting the metal pattern 12 in the stove for heating into, with regulate its height with respect to hot air blow port 16, thereby make hot blast 14 that the hot air blow port 16 of stove inner bottom surface 18 blows out more efficiently to the inner surface heating of metal pattern 12.

2. forming face

Shown in Fig. 3 (b), metal pattern 12 also can separate independence.But the forming face 85 that preferably substantially has tablet more than 2 places.

Its reason is, because according to this metal pattern, with can be shaped simultaneously tablet more than 2 of a metal pattern.

At this, forming face substantially is provided with more than 2 places, or forming face is one but when heating a plurality of metal pattern, as Fig. 6 (a) and (b), for the rotating shaft direction X of metal pattern 12, in forming face 85 configurations of staggering separately, the path (figure slightly) that powder is come in and gone out easily is set preferably.

Its reason is, by adopting such structure, in powder rolling screw-threads operation, when allowing metal pattern 12 rotations, can make powder enter separately forming face easily, and can easily obtain having the tablet of uniform thickness.

2. powder rolling screw-threads portion

So, in the metal pattern cooling end, preferably possess sprayer unit 121 and the shower bath 98 shown in Fig. 8 (b) shown in Figure 10 (a) as cooling device.Its reason is, by adopting such structure, can prevent the generation of the fire damage of metal pattern and crackle etc. effectively.

And, preferably shower bath and sprayer unit are connected on the feed trough, decide spray amount and shower amount according to the switching device shifter that is located at control valve on the blow-off outlet etc.

(2) temperature

The cooling tablet, preferably the surface temperature control of this tablet in 30～100 ℃ scope.

Its reason is, during as 30 ℃ of the surface temperature deficiencies of this tablet, and the lower limit temperature adjustment of the subsequent processing surface treating part difficulty that becomes.For example, be difficult to form the surface-treated layer of handling through the flame that silicifies sometimes.On the other hand, the surface temperature of this tablet is as surpassing 100 ℃, and the hardness of the tablet of subsequent processing surface treating part is not enough, can occur being difficult to form the situation of surface-treated layer on the contrary.

So the surface temperature control during cooling tablet in the metal pattern cooling end is better in 35～80 ℃ scope, the scope that is controlled at 40～60 ℃ is interior for better.

And, in the surface temperature of the tablet of metal pattern cooling end, be after implementing cooling processing, use the surface temperature of the tablet that land surface pyrometer etc. measures immediately.

4. metal pattern exchange portion

(1) structure

Powder rolling screw-threads forming machine of the present invention preferably has metal pattern exchange portion again.Promptly, utilize metal pattern exchange portion, the change midway that is shaped at the powder rolling screw-threads be used to the to be shaped metal pattern of diverse tablet, in the powder rolling screw-threads is shaped, the situation of metal pattern damage takes place sometimes, even in this case, when allowing the work of powder rolling screw-threads forming machine, also can exchange metal pattern.

So, shown in Fig. 1 and 2, possess at least when the plural brace table that is used for mounting metal pattern 60 66 is arranged, preferably support platform 66 separately can move by external control.

At this, with reference to Fig. 2, to a hypothesis metal pattern (60d) breakage among a plurality of metal patterns (60b, 60c, 60d), the structure that is exchanged for new metal pattern 60f is made specific description.

For example, certain constantly, the 1st metal pattern 60c is placed on powder rolling screw-threads operation in powder rolling screw-threads portion (A portion), the 2nd metal pattern 60c is placed on heating process in metal pattern heating part (B portion), and the 3rd metal pattern 60d is placed on refrigerating work procedure in metal pattern cooling end (C portion).Then, find under the situation of crackle among the 3rd metal pattern 60d in metal pattern cooling end (C portion), the 3rd metal pattern 60d, not resembling usually in the surface treating part (D portion) of the back that comes metal pattern cooling end (C portion) by surface treatment, but be stopped at institute's allocation with the common metal pattern exchange portion (E portion) of surface treating part (D portion).Simultaneously, on the 1st brace table 66a, fallen mounting.Then, the 3rd the metal pattern 60d that has damaged on the 1st brace table 66a moves towards an end transverse direction of the board 69 that contains pulley.On the contrary,, moved by anti-transverse direction, be positioned in the position of metal pattern exchange portion (E portion) at the other end of board 69 by the new metal pattern 60f on the 2nd brace table 66b of pre-mounting.

Like this, can be in metal pattern exchange portion (E portion), damaged metal pattern 60d is exchanged into new metal pattern 60f, is shorter than surface treatment time or powder rolling screw-threads curring time and metal pattern heat time heating time by making its operating time, thereby reduces influence other operation.

(2) configuration

Metal pattern exchange portion preferably is configured as the subsequent processing of metal pattern cooling end.

Its reason is, by adopting such structure, because be metal pattern in the exchange in the stage of being cooled, in advance or there is no need to heat immediately the metal pattern of new use after the exchange, can more successfully move on to subsequent processing.In addition, if the metal pattern under the state that is cooled, the operation after also exchanging safely.

4. surface treating part

(1) surface processing device

The kind of surface processing device there is no special restriction.For example, preferably in handling, ozone treatment as follows, plasma treatment, sided corona treatment, electrion processing, UV treatment and the flame that silicifies be used to implement at least a surface-treated surface processing device.

Its reason is, if this surface processing device because surface processing device and handling part are smaller, even powder rolling screw-threads forming machine in the past also can organize with comparalive ease into.In addition, if this surface processing device, because tablet is cooled to institute's fixed temperature, so can in the shorter time, carry out surface treatment.

And among these surface processing devices, comparatively ideal is to be used to implement to silicify the surface processing device that flame handles.Its reason is, if the flame that silicifies is handled, outside moisture and dust etc. are cut down few to the effect of surfaction layer, form the tablet of surfaction layer can be for a long time as more than 6 months former state take care of.

1. ozone treatment

Ozone treatment is by the surface irradiation ozone material (O to tablet ₃) make surperficial acidifying, to form the surface treatment of surfaction layer.

2. plasma treatment

Plasma treatment is the plasma species (reinforcer, free radical thing, ion thing etc.) that is generated by plasma discharge by the surface irradiation to tablet, and etched surfaces is to form the surface treatment of surfaction layer.

3. sided corona treatment

Sided corona treatment is to generate polar group etc. by Corona discharge Treatment is implemented on the surface of tablet, to form the surface treatment of surfaction layer.

4. electrion is handled

It is to implement electrion repeatedly by the surface to tablet that electrion is handled, and the part on insulation breakdown surface is to form the surface treatment of surfaction layer.

5. UV treatment

UV treatment is by the surface institute of tablet being shone quantitatively the long ultraviolet ray of institute's standing wave, making a part of activate on surface, with the surface treatment of formation surfaction layer.

6. the flame that silicifies is handled

The flame that silicifies processing is the surface to tablet, and jet contains the flame of silane compound fuel gas comprehensively or partly, is formed the surface treatment of silicon dioxide layer by the flame analyte of silane compound.

At this, preferably the boiling point of silane compound (under the atmospheric pressure) is controlled in 10～100 ℃ the scope, for better, in 20～60 ℃ the scope the best in 15～80 ℃ the scope.Its reason is, when 10 ℃ of the boiling point of this silane compound such as less thaies, and high volatility, operating difficulties sometimes.On the other hand, the boiling point of this silane compound is when surpassing 100 ℃, significantly descend with the Combination of combustion-supporting property gases such as air and combustion adjuvant, the easy imperfect combustion of silane compound, the surfaction effect is inhomogeneous sometimes, be difficult to keep for a long time the upgrading effect.

And, do not have special restriction about the kind of silane compound, for example, can be alkyl silane cpd and alkoxysilane compound containing trialkylsilyl group in molecular structure or its sex change thing.In addition, among these compounds, alkyl silane cpd is general lower boiling many, through heating easy gasification, because of it can be equably mixes with air etc., so be desirable silane compound.

More specifically, tetramethylsilane and tetraethyl silane, because of its boiling point is very low, easily and mixing such as air, so be desirable silane compound.The halogen silane compound of 1,2 ring tetramethylsilane etc. is because of its surfaction effect is quite outstanding, so be desirable silane compound.

In addition, the entire amount of burning gases preferably is controlled at 1 * 10 to the addition of silane compound in fuel gas during as 100 moles of % ^-10In the scope of～10 moles of %, be controlled at 1 * 10 ^-9For better, be controlled at 1 * 10 in the scope of～5 moles of % ^-8Be best in～1 mole the scope.Its reason is, as the addition discontented 1 * 10 of this silane compound ^-10During mole %, can not find the upgrading effect sometimes.On the other hand, when surpassing 10 moles of % as the addition of this silane compound, the Combination of silane compound and air etc. descends, and the unburnt phenomenon of silane compound is arranged thereupon.

In addition, when implementing to silicify the flame processing,, preferably in burning gases, add combustion-supporting property gas usually because be easy to control flame temperature.As such combustion-supporting gas, propane flammable gas, natural-gas, oxygen are arranged, air, hydrogen etc.And, when burning gases being put into hermetically sealed can use, preferably use propane gas and compressed air etc. as such combustion-supporting gas.

In addition, all amounts of burning gases during as 100 moles of %, preferably being controlled at the amount of this combustion-supporting gas in the scope of 80～99.9 moles of %, for better, is the best in the scope of 90～99 moles of % in the scope of 85～99 moles of %.Its reason is, if during 80 moles of % of the amount deficiency of this combustion-supporting gas, the Combination of silane compound and air etc. descends, and the unburnt phenomenon of silane compound is arranged thereupon.On the other hand, if when the addition of this silane compound surpasses 99.9 moles of %, then can not find the upgrading effect sometimes.

(2) configuration

In order to handle the surface of tablet effectively, surface treating part preferably is configured to the subsequent processing of metal pattern cooling end.

Its reason is, if surface treating part becomes a last operation of metal pattern cooling end, sometimes the surface of tablet can not harden to decide degree, the surface treatment effect of the flame processing etc. of can not finding to silicify.

In addition, preferably surface treating part and metal pattern exchange portion are made as one.That is, as shown in Figure 1, the below that is preferably in the brace table 66 of metal pattern exchange portion has surface processing device 68.

Its reason is, in metal pattern exchange portion, in a single day be positioned on the brace table 66 at the metal pattern 60 that the metal pattern cooling end is cooled, utilize this state by tablet is implemented surface treatment, when the space can be saved, can obtain the good tablet of adherence more efficiently.

5. tablet

(1) form

Form about tablet, its constituent material does not have special restriction, for example, preferably constitute by at least a resin in epoxy resin, Corvic, acrylic resin, polyene connection resin, urethane resin, polycarbonate resin, the mylar.

Its reason is, by adopting such structure, can obtain versatility height, cheapness, and ornamental good tablet.

In addition, preferably the THICKNESS CONTROL of tablet in the scope of 10～500 μ m.Its reason is, if during the value of the discontented 10 μ m of the thickness of this tablet, the intensity of the machinery of tablet and durability significantly descend sometimes.On the other hand, if when the thickness of this tablet surpasses 500 μ m, then operate sometimes and the difficulty of adhering.Therefore, the THICKNESS CONTROL of tablet in the scope of 25～300 μ m for better.
