Then, the structure of hot pressing mechanism 300 described.Fig. 9 is the side cross-sectional view of hot pressing mechanism 300.In addition, Figure 10 is the front elevation of watching hot pressing mechanism from downstream (the II-II direction of Fig. 2 to view).As shown in Figure 9, hot pressing mechanism 300 is at the top hot pressing dish 322 formed movably along the vertical direction and the device that relatively between the fixing bottom hot pressing dish 324 of lower section frame 230, machined object carried out to hot pressing.Top hot pressing dish scaffold 312 is fixedly attached to upper frame section 210 in conveyance direction both sides.Top hot pressing dish 322, below by the hot pressing dish, moving with cylinder mechanism 370 and movable plate seat 336 and hanging from top hot pressing dish scaffold 312.In addition, bottom hot pressing dish 324 is fixed on workbench dish seat 314, and wherein, this workbench dish seat is fixedly attached on lower section frame section 230 by pillar 244.
In embodiments of the present invention, as shown in Figure 9 and Figure 10, top hot pressing dish 322, move with cylinder mechanism 370 and hang from top hot pressing dish scaffold 312 (6) hot pressing dish by 3.As shown in Figure 10, cylinder mechanism 370 has cylinder 371, the bar 372 extended from this cylinder 371 downwards and is arranged on the link mechanism 373 of the front end of this bar 372.Cylinder 371 is fixed on the side of top hot pressing dish scaffold 312.In addition, bar 372 links by link mechanism 373 with movable plate seat 336.Thereby, by drive rod 372, can make movable plate seat 336 move up and down.In addition, the hot pressing dish moves with cylinder mechanism 370 and makes bar 372 advance and retreat by pneumatics or oil sector.
In addition, in embodiments of the present invention, 6 pressure cylinder mechanisms 340 are arranged at top hot pressing dish scaffold 312.After moving by the hot pressing dish and making top hot pressing dish 322 descend to form machined object to be clamped in the state between the hot pressing dish with cylinder mechanism 370, top hot pressing dish 322 is pressed downwards, suppressed.Each pressure cylinder mechanism 340, have sleeve 344 that piston 342, piston 342 plant and for sleeve 344 being fixed on to the following fixing with plate 346 of top hot pressing dish scaffold 312.Fixing with plate 346, by integrated such as the method such as welding and sleeve 344, by with screw 348 (Figure 10), fixed frame 346 being fixed in to top hot pressing dish scaffold 312, sleeve 344 is installed on to top hot pressing dish scaffold 312.In addition, movable plate seat 336 is fixed on the lower end of piston 342.Thereby, control the oil pressure in sleeve 344 by not shown oil pressure pump, can be with desirable load compacting machined object.
In addition, as shown in Figure 9 and Figure 10, below movable plate seat 336, in the width both sides of top hot pressing dish, be provided with the top distance rod 352 that a plurality of verticals down extend.Similarly, above workbench dish seat 314, in the width both sides of bottom hot pressing dish, be provided with the bottom distance rod 354 that a plurality of verticals up extend.Each of top distance rod 352, with each of bottom distance rod 354, relatively configure, when by pressure cylinder mechanism 340 so that top hot pressing dish 322 approaches the mode of bottom hot pressing dish 324 while being driven, the upper surface butt of the lower surface of top distance rod 352 and bottom distance rod 354, top hot pressing dish 322 can not further descend again.That is, by distance rod 352,354, the top hot pressing dish 322 in the time of can controlling hot pressing and the thickness of the interval machined object of bottom hot pressing dish 324.
Top hot pressing dish 322 and bottom hot pressing dish 324 equal internal heater (not shown), can make each hot pressing dish be warming up to desirable temperature.In addition, between movable plate seat 336 and top hot pressing dish 322, be provided with insulation 334, make the heat of top hot pressing dish 322 can not escape to piston side.Similarly, between workbench dish seat 314 and bottom hot pressing dish 324, be provided with insulation 338, make the heat of bottom hot pressing dish 324 can not escape to workbench dish seat 314 sides.
As shown in Figure 9, in embodiments of the present invention, in hot pressing mechanism 300, the first heating region 300b of the substantial middle section that be set with the preheated zone 300a that is positioned at upstream side, is positioned at conveyance/direction of retreat and be positioned at the second heating region 300c in downstream.The size of the conveyance direction that each is regional is roughly the same, disposes two pressure cylinder mechanisms 340 in each zone.In addition, the amount of feeding of the action of the size of each regional conveyance direction and the circulation based on clamper 150 (Fig. 2) and the machined object that produces about equally.Thereby in the present embodiment, machined object is suppressed successively in preheated zone 300a, the first heating region 300b, the second heating region 300c.
In addition, the length of the temperature of top hot pressing dish and bottom hot pressing dish 322,324, distance rod 352,354 (instant heating platen interval) can be set as each the different value for regional 300a, 300b, 300c.That is, the thickness of machined object, according to the structure of machined object, characteristic, size etc., by regulating the length of corresponding distance rod 352,354, can be controlled each zone individually.
In addition, each of pressure cylinder mechanism 340 couples of regional 300a, 300b, 300c drives individually.In the present embodiment, the load that puts on machined object in each zone, determined by the length of distance rod 352,354, size and the characteristic of machined object.; after distance rod 352 and 354 butts; even make the oil pressure rising in pulley 344, the load that puts on movable plate seat 336 is increased; the part that this load increases; not by machined object M but born by workbench dish seat 314 by distance rod 352,354,322,324 pairs of loads that put on machined object M of hot pressing dish do not exert an influence yet.In other words, 340 pairs of movable plate seats 336 of each pressure cylinder mechanism apply the load that can suppress fully machined object M and get final product, even apply, surpass in this load, also only become the loss of power.And, in the present embodiment, owing to being the value different for each by the length setting of the degree of the reaction of machined object, distance rod 352,354, therefore generally speaking, should put on the size of the load of machined object, different for each zone.Thereby, by control individually the load of the piston 342 that puts on pressure cylinder mechanism 340 for each zone, can be only in order to suppress each the required load of machined object M that is disposed at regional 300a, 300b, 300c, to drive top hot pressing dish 322, the loss of power can be suppressed for necessary bottom line.
By the machined object after hot pressing mechanism 300 hot pressing, follow by clamper 150 conveyances to the mechanism 400 of colding pressing.As shown in Figure 2, the mechanism 400 of colding pressing has the top cooler pan 422 hung from upper frame section 210 by pressure cylinder mechanism 440 and is fixed in the bottom cooler pan 424 on lower section frame section 230 by cramp bar 248.At top cooler pan 422, bottom cooler pan 424, be provided with for making the pipeline of cold-producing medium (water, air, wet goods) in inner loop.By cold-producing medium is circulated in pipeline, the temperature of cooler pan 422,424 keeps below the temperature of hot pressing dish 322,324.In addition, pressure cylinder mechanism 440 can so that top cooler pan 422 relative bottom cooler pan 424 separation/approaching modes driven.
In the present embodiment, by driving pressure cylinder mechanism 440, top cooler pan 422 is descended, can make machined object and top cooler pan 422, bottom cooler pan 424 be close to.Now, due to the temperature of machined object, than two cooler pan 422,424 height, so 422,424 produce hot transfer from machined object to cooler pan, the temperature of machined object descends.Thereby, can be cooling by the machined object after hot pressing mechanism 300 hot pressing by the mechanism 400 of colding pressing.In addition, the conveyance direction size of top cooler pan 422 and bottom cooler pan 424, less times greater than the amount of feeding of 1 time produced based on clamper 150, the machined object the hot pressing of therefore discharging successively from hot pressing mechanism 300 is cooling by the mechanism 400 of colding pressing without omitting ground.
In addition, as shown in Figure 9, at the conveyance direction two ends of hot pressing mechanism 300, be provided with the mip rolls mechanism 361,362,363,364 for supporting steel band 123,143.Mip rolls mechanism 361 in the downstream of hot pressing mechanism 300,362 upstream side support respectively steel band 123,363 in downstream, 364 at upstream side, support respectively steel band 143.
Then, the structure of each mip rolls mechanism 361~364 described.As shown in Figure 9, mip rolls mechanism 361~364 has mip rolls 361a~364a and at the bearing portion 361b~364b of rotatably mounted this mip rolls in two ends.At this, the application of force unit of mip rolls mechanism is described.Figure 11 means the mip rolls mechanism 361 in downstream and 363 side view.As shown in the figure, each of mip rolls 361a, 363a, by cylinder mechanism 361c, 363c flexibly to the steel band side application of force.That is, the mip rolls 361a of the steel band 123 of supporting upside band mechanism 120 application of force downwards.On the other hand, the mip rolls 363a of the steel band 143 of supporting downside band mechanism 140 application of force upward.In addition, the mip rolls mechanism 362 and 364 of upstream side also is respectively arranged with and mip rolls mechanism 361 and 363 roughly the same cylinder mechanisms.
When top hot pressing dish 322, with bottom hot pressing dish 324, separate while not carrying out hot pressing, mip rolls mechanism 361~364 pairs of steel bands, 123,143 application of forces, make steel band 123,143 separate a little with bottom hot pressing dish 322,324 with top hot pressing dish.In addition, when making top hot pressing dish 322 descend from this state, steel band 123 and top hot pressing dish 322 butts of upside band mechanism 120, then steel band 123 becomes one and moves downwards with top hot pressing dish 322.Now, control the cylinder mechanism of mip rolls mechanism 361,362, make mip rolls 361a, 362a also move again under the state with steel band 123 butts downwards.Then, the steel band 123 of upside band mechanism 120 is by steel band 143 butts of machined object and downside band mechanism 140, and then when top hot pressing dish 322 descends, along with the steel band 143 of the mobile downside band mechanism 140 of top hot pressing dish 322 also descend again and with bottom hot pressing dish 324 butts.Now, mip rolls 363a, 364a also move downwards under the state with steel band 143 butts again.By processing as previously discussed, machined object is pressed between the hot pressing dish.Like this, in the present embodiment, the mode that can strongly not collide the angle of hot pressing dish 322 and 324 with steel band 123,143 applies active force to mip rolls mechanism 361~364, and therefore band is not fragile.
In addition, after compacting finishes, top hot pressing dish 322 rises, and from bottom hot pressing dish 324, separates hastily.Now, the cylinder mechanism of mip rolls mechanism 361~364 is controlled, make (for example 1 second) top steel band 123,143 and machined object M butt during of short duration, then, steel band 123,143 is moved gradually to top hot pressing dish and bottom hot pressing dish 322,324.Thereby moving up and down of the steel band by rapidly, can not damage machined object.
In addition, when clamper 150 (Fig. 4) while controlling machined object, movement along with steel band 123,143, mip rolls 362a and the 364a of upstream side move in mode close to each other, and, to steel band 123,143 application of forces, make the bottom part 123a of steel band 123 and the top part 143a of steel band 143 become approximate horizontal.Thereby the edge of the grip plate 151,152 of clamper can not damage steel band.
In the present embodiment, as shown in Figure 2, in the bottom of the top of steel band 123 part 123b and steel band 143, part 143b is provided with remover (remover) 125 and 145.Remover 125,145 possesses such as scraper etc., will remove due to the resin sheet that compression process is attached to the outer peripheral face of steel band 123,143.
Then, the compacting of the machined object of the pressure setting 1 of the embodiments of the present invention based on above-mentioned explanation sequentially described.In addition, in the following description, the preforming material lamellar body that will comprise heat reactive resin forms as machined object M.In addition, to from the downstream front end of machined object M, the length of the part of the amount of feeding based on clamper 150 partly be defined as first, by relative first, the length of the amount of feeding part adjacent with upstream side partly is defined as second portion, by relative second portion, the length of the amount of feeding part adjacent with upstream side partly is defined as third part, and by relative third part, the length of the amount of feeding part adjacent with upstream side partly is defined as the 4th part.
At first, by clamper 150 (Fig. 4), the preheated zone 300a (Fig. 9) by first's conveyance to hot pressing mechanism 300.Then, drive the hot pressing dish to move with cylinder mechanism 370 (Figure 10), the first of machined object M is clamped between hot pressing dish 322,324.And then, driving pressure cylinder mechanism 340, the first of compacting machined object M.At this, the temperature of the hot pressing dish 322,324 in the 300a of preheated zone, lower than the solidification temperature of the resinous principle of machined object, is controlled as the temperature that approaches glass transition temperature.Therefore, the resin of first is partly softening, so but, because the heat cure of the low machined object of temperature is carried out hardly, first is adjusted to desirable thickness.
Then, make the oil pressure of pressure cylinder mechanism 340 reduce and move with cylinder mechanism 370 and make hot pressing dish 322,324 be separated from each other to decontrol machined object M by the hot pressing dish.And then, by clamper 150 conveyance machined object M on the conveyance direction.Consequently, the first of machined object M moves to the first heating region 300b, and in addition, second portion moves to preheated zone 300a.Then, drive the hot pressing dish to move with cylinder mechanism 370, make hot pressing dish 322,324 close to each other, and 340 pairs of top hot pressing dishes 322 of driving pressure cylinder mechanism apply load.Thus, the first of machined object M is at the first heating region 300b, and in addition, second portion is pressed respectively at preheated zone 300a.At this, the temperature of the hot pressing dish 322,324 in the first heating region 300b, higher than the hot pressing dish temperature in the 300a of preheated zone, is therefore carried out with certain degree in first's heat cure reaction of machined object M.In addition, at preheated zone 300a, adjust the shape of second portion.In addition, machined object M shrinks a little due to the heat cure reaction, therefore set the interval of distance rod 352,354 (Figure 10), make the interval of the hot pressing dish when the first heating region 300b compacting machined object compare a little and narrow down with the hot pressing dish interval in the 300a of preheated zone.
Then, make the oil pressure of pressure cylinder mechanism 340 reduce and move with cylinder mechanism 370 and make hot pressing dish 322,324 be separated from each other to decontrol machined object M by the hot pressing dish.And then, by clamper 150 conveyance machined object M on the conveyance direction.Consequently, the first of machined object M moves to the second heating region 300c, and second portion moves to the first heating region 300b, and third part moves to preheated zone 300a.Then, drive the hot pressing dish to move with cylinder mechanism 370, make hot pressing dish 322,324 close to each other, and 340 pairs of top hot pressing dishes 322 of driving pressure cylinder mechanism apply load.Thus, the first of machined object M is at the second heating region 300c, and second portion is at the first heating region 300b, and third part is pressed respectively at preheated zone 300a.At this, temperature and the first heating region 300b of the hot pressing dish 322,324 in the second heating region 300c are roughly the same.Machined object M, by being heated successively at the first heating region 300b and the second heating region 300c, proceed to the heat cure reaction last.Thereby the first of machined object M is configured as desirable cross sectional shape.In addition, at the first heating region, the heat cure of second portion reaction is carried out with certain degree.In addition, at preheated zone 300a, adjust the shape of third part.In addition, heat cure reaction at the second heating region machined object M is further carried out and the machined object contraction, therefore set the interval of distance rod 352,354, make the interval of the hot pressing dish when the second heating region 300c compacting machined object compare a little and narrow down with the hot pressing dish interval in the first heating region 300b.
Then, make the oil pressure of pressure cylinder mechanism 340 reduce and move with cylinder mechanism 370 and make hot pressing dish 322,324 be separated from each other to decontrol machined object M by the hot pressing dish.And then, by clamper 150 conveyance machined object M on the conveyance direction.Consequently, the first of machined object M from hot pressing mechanism 300 discharge, by conveyance between the cooler pan 422,424 of the mechanism 400 of colding pressing.In addition, second portion moves to the second heating region 300c, and third part moves to the first heating region 300b, and the 4th part moves to preheated zone 300a.Then, drive the hot pressing dish to move with cylinder mechanism 370 and pressure cylinder 440 (Fig. 2), make hot pressing dish 322 and 324 and cooler pan 422 and 424 close to each other, and 340 pairs of top hot pressing dishes 322 of driving pressure cylinder mechanism apply load.Thus, the first of machined object M and cooler pan 422,424 butts, first is cooled.In addition, second portion is at the second heating region 300c, and third part is at the first heating region 300b, and the 4th part is pressed respectively at preheated zone 300a.
Like this, in the pressure setting 1 of present embodiment, conveyance and the compacting of machined object hocket, and can form and compare the machined object M that conveyance direction size is larger, rectangular with hot pressing dish, cooler pan.In addition, at first machined object M adjusts shape at preheated zone 300a, then at the first heating region 300b and the second heating region 300c, by heat cure, reacts shaping, then cooling by the mechanism 400 of colding pressing.Like this, be configured to and at first carry out after shape is adjusted in preheating carrying out hot pressing, therefore can not produce due to the defect of carrying out the machined object M that the heat cure reaction causes (albefaction of the flowing of the disorder of the fiber of preforming material lamellar body, resin, machined object, uneven thickness etc.) not adjusting under the state of shape.In addition, in the present embodiment, preheating and hot pressing both sides are undertaken by a pair of jointless large-scale hot pressing dish 322,324.Therefore, even, in the situation that the machined object that conveyance direction size is greater than to the hot pressing dish forms, can not produce the such defect of seam yet.
In addition, in the present embodiment, at the first heating region 300b and these two zones of the second heating region 300c, carry out the heating of machined object M.That is the time of, carrying out hot pressing is the twice of preheating time.Even, at the preheated zone 300a suppressed with low temperature, the heat cure of machined object M is also carried out a little.Therefore in the present embodiment, can make like this time of hot pressing become longer than preheating time, can carry out heat cure hardly and adjust the shape of machined object M and complete heat cure at heating region at preheated zone 300a.In addition, in the present embodiment, two heating regions are prepared in relative 1 preheated zone, but the present invention is not limited to said structure, and each regional quantity can suitably change according to the resin material that forms machined object.
In addition, in the present embodiment, the material that comprises heat-curing resin is carried out to hot pressing, but the present invention is not limited to this structure, also can be applicable to the machined object that comprises thermoplastic resin.That is,, in the situation that the machined object that comprises thermoplastic resin is carried out to hot pressing, at first in preheated zone, with low temperature, adjust the shape of machined object.Now, machined object due to not too be heated thereby viscosity higher, prevent flowing of resin.Then, carry out the shaping of machined object with high temperature at the first heating region and the second heating region, at the cooler pan solid shape.
In addition, in the present embodiment, clamper 150 relatively hot press mechanisms 300 are configured in the direction of retreat side.Yet the present invention is not limited to this structure, clamper 150 also can relatively hot press mechanism 300 be configured in conveyance direction side hot pressing mechanism 300 with cold pressing between mechanism 400 or the relative mechanism 400 of colding pressing is configured in conveyance direction side.
In addition, in the present embodiment, carry out conveyance machined object M by steel band 123,143 rotations that make steel, but the present invention is not limited to this structure.That is, also can not use steel band 123,143, and the endless belt that uses other metal endless belts, formed by heat-resistant resins such as polyimides.
In addition, in the present embodiment, top hot pressing dish 322 and bottom hot pressing dish 324 are built-in with heater, heat thus two hot pressing dishes.Yet the present invention is not limited to this structure, also can be configured to by for example making thermal medium circulate and be heated in the hot pressing dish.
