By this top nozzle 20, cooling medium is blown to the top 1a of extrded material 1.
According to Fig. 2 and Fig. 3, the example of concrete shape of the installation of above-mentioned top nozzle 20 is described.
With substrate 21 on initial roller-way 13 adjoining positions on, a plurality of base stations 22, for example 3 base stations 22 separate certain interval in the direction of extrusion and are set up.
On this each base station 22, install first 23 and second 24 abreast to the direction of extrusion.
Can rotate freely for first 23 and second 24, an end of an end of the first arm 25 and second arm 26 is fixing respectively.The other end of the other end of the first arm 25 and second arm 26 can be connected on the carriage release lever 27 by the 3rd 28, the 4th 29 with rotating freely, forms 4 parallel joint connecting rods 30.
Fixed lateral parts 31 on above-mentioned each carriage release lever 27.This each cross member 31 for long size, on this cross member 31, is installed a plurality of pipes 32 respectively in the direction of extrusion, right angle orientation devices spaced apart in the direction of extrusion, the one the second 3rd pipe 32 for example, respectively manage on 32 at this, top nozzle 20 is installed downwards in direction of extrusion devices spaced apart.
Above-mentioned each first 23 is driven respectively by electro-motor 33.
That is, last cooling end 18a is divided into a plurality of in the direction of extrusion, moves in cool position and preservation position individually respectively.
Because like this, make first 23 just changeing by electro-motor 33, cross member 31 moves to the top position of the initial roller-way 13 shown in the solid line of Fig. 2, and top nozzle 20 moves to above-mentioned cool position.
Make second 23 counter-rotating by motor 33, cross member 31 moves to shown in the imaginary line of Fig. 2 and positions initial roller-way 13 partition distance, and top nozzle 20 moves to above-mentioned preservation position.
In addition, in direction of extrusion devices spaced apart 3 cross members 31 are set, each cross member 31 can be moved to respectively individually initial roller-way 13 the top position and with the position of initial roller-way 13 partition distance, the top nozzle of installing 20 can be moved to individually cool position respectively on each cross member 31 and preserve the position.
Therefore,, each cross member 31 is moved to position with initial roller-way 13 partition distance, make it not disturb with puller 15 in when beginning extruding.
Begin extruding, puller 15 moves to the direction of extrusion, and during whenever by cross member 31, this cross member 31 moves to the top position of initial roller-way 13 successively, and top nozzle 20 is positioned at cool position, can pre-cooled extrded material above.
Therefore, compare for the situation of one, can cool off the beginning period of extrded material in advance with cross member 31.
Above-mentioned down cooling end 18b as shown in Figure 2, following nozzle 40 moves freely on the direction of extrusion and right angle orientation (arrow c direction) below initial roller-way 13, this time nozzle 40 blows to cooling medium the following 1b of the extrded material 1 on the initial roller-way 13 up.
Specifically, as Fig. 2 and shown in Figure 4, in substrate 21, on a plurality of pallets 41 that direction of extrusion devices spaced apart is provided with, the bar 42a of rod-type moving body 42 fixes towards the direction of extrusion and right angle orientation, across this each flexible pipe 42b, the moving body 43 of long size is installed towards the direction of extrusion, mounting pipe 44 on this moving body 43 on this pipe 44, will descend nozzle 40 upwards to install in direction of extrusion devices spaced apart.
Above-mentioned nozzle 40 down between the roller 13a of its adjacency, blows to cooling medium the following 1b of extrded material 1 between the roller 13a of the adjacency of initial roller-way 13.
Above-mentioned rod-type moving body 42 is electrodynamic types.For example, by being arranged on the electro-motor rotary pinion on the flexible pipe 42b, with this pinion and the tooth bar engagement that is arranged on the bar 42a, by with the electro-motor rotary pinion, with respect to bar 42a, flexible pipe 42b slides.
In addition, also above-mentioned moving body 43 can be divided into a plurality ofly, it is a plurality of to descend cooling end 18b to be divided in the direction of extrusion.
The above-mentioned first sidepiece cooling end 18c and the second sidepiece cooling end 18d are same shapes, when horizontal sidepiece nozzle 50 strides across the preservation position of not disturbing with puller 15 and moves (lifting) with cool position that a side's of extrded material 1 side 1c, the opposing party's side 1d faces, move at the above-below direction (arrow d direction among Fig. 2) of its cool position.
Specifically, as Fig. 2, Fig. 3, shown in Figure 5, at two side positions of initial roller-way 13, the movable body 51 of long size sets a plurality of in direction of extrusion devices spaced apart, for example 3.
This each movable body 51 has a plurality of sliding bars 52, this each sliding bar 52 above-below direction can be free to slide the ground intercalation be arranged on the vertical guiding 53 in the substrate 21.In view of the above, but each movable body 51 free lifting.
On above-mentioned each movable body 51, pipe 54 is mounted to the direction of extrusion.On this pipe 54, a plurality of sidepiece nozzles 50 are at the length direction of extrded material, and devices spaced apart is laterally installed.
On above-mentioned each movable body 51, tooth bar 55 is vertically fixing.Drive the pinion 56 of tooth bar 55 engagements therewith by electro-motor 57 rotations.
Therefore, if by electro-motor 57 rotation driving pinions 56, then by tooth bar 55, movable body 51 moves up and down, sidepiece nozzle 50 cool position with preserve when the position moves, move at the above-below direction of cool position, can adjust the height of sidepiece nozzle 50.
In addition, because but a plurality of movable bodys 51 are installed respectively on direction of extrusion devices spaced apart free lifting ground, so it is same as described above, when the extruding beginning, when puller 15 whenever passes through movable body 51, its movable body 51 can move to cool position successively, can begin to cool down the following period of extrded material in advance.
That is, the first sidepiece cooling end 18c and the second sidepiece cooling end 18d are divided into a plurality of in the direction of extrusion, move to cool position respectively individually and preserve the position.
Below, pre-cooled 18 action control loop is described according to Fig. 6.
If the cooling medium supply source, for example electromagnetic switch valve 62 is passed through by open in the outlet road 61 of cooling water pump 60, and then cooling medium is pressed to 3 top nozzles 20, following nozzle 40, sidepiece nozzle 50 respectively through each pipe 32,44,54.
Above-mentioned each electromagnetic switch valve 62 is maintained in its closed position by spring force, by to 63 energisings of electromagnetism solenoid, makes it to be positioned at open position.
Only spray cooling medium from the nozzle that is connected with the electromagnetic switch valve 62 that is positioned at open position.
Above-mentioned each electromagnetism solenoid 63 is by controller 64 control energisings.
This controller 64 drives control electro-motor 33, the electro-motor 42c of rod-type moving body 42, electro-motor 57.
In above-mentioned controller 64,, the nozzle of ejection cooling medium and the position of nozzle thereof are remembered as cooling setpoint information with the cross sectional shape of corresponding extrded material, for example based on the cross sectional shape of the model or the figure number of extrded material.
The staff is when carrying out squeeze job, whether judgement exists the part that is difficult to cool off in the part of the outer peripheral face of extrded material, under situation about being judged as, according to its cross sectional shape, with the nozzle of ejection cooling medium and the position of nozzle, from being input to the cooling setpoint information of controller 64 in advance, the staff selects, when the electromagnetism solenoid 63 of corresponding electromagnetic switch valve 62 is switched on, by driving control electro-motor 42c, electro-motor 57, electro-motor 57, only cool off the part that is difficult to cool off at the extrded material outer peripheral face.
For example, extrded material 1X at cross sectional shape that will be shown in Figure 10 (A), as shown in Figure 7, make under the situation of first plate-like portion 2 and extrusion molding relative with the first sidepiece cooling end 18c, drive the electro-motor 57 of the first sidepiece cooling end 18c, when making its sidepiece nozzle 50 be positioned at cool position, adjust height, make it to become the height H 1 of the regulation relative with the above-below direction central portion of first plate-like portion 2.Above-mentioned height is the height that begins above initial roller-way 13.
This action is carried out during at every turn by movable body 51 successively at puller 15.
If sidepiece nozzle 50 reaches the take the altitude H1 of institute, after perhaps puller 15 passed through, electromagnetism solenoid 63 energisings to the electromagnetic switch valve 62 of connection on its sidepiece nozzle 50 became open position.
In view of the above, cooling medium only blows to first plate-like portion 2 that is difficult to cool off of extrded material 1, pre-cooled this first plate-like portion 2.
Extrded material 1Y at cross sectional shape that will be shown in Figure 10 (B), as shown in Figure 8, make hollow bulb 5 under the situation of the first sidepiece cooling end 18c extrusion molding, same as described above, make the height of sidepiece nozzle 50 become specified altitude H2 towards the above-below direction central portion of hollow bulb 5.
Extrded material 1Z at cross sectional shape that will be shown in Figure 10 (C), as shown in Figure 9, make hollow bulb 7 and under the situation of extrusion molding towards the first sidepiece cooling end 18c, because the top 7a of its hollow bulb 7, following 7b, a side's side 7c is difficult to cooling than other parts, so cool off above-mentioned each face by last cooling end 18a, following cooling end 18b, the first sidepiece cooling end 18c.
The action of the first sidepiece cooling end 18c is same as described above, makes the height of its sidepiece nozzle 50 become the relative specified altitude H3 of above-below direction central portion with a side's of hollow bulb 7 side 7c.
Electromagnetism solenoid 63 to the electromagnetic switch valve 62 that is connected with the most amesiality top nozzle 20 (top nozzle 20 relative with the right angle orientation central portion with the direction of extrusion among the 7a on hollow bulb 7) in 3 top nozzles 20 is switched on.
Drive the electro-motor 42c of cooling end 18b down, make down the direction of extrusion among nozzle 40 arrival and the 7b below hollow bulb 7 and the relative position of central portion of right angle orientation.
To descending electromagnetism solenoid 63 energisings of the electromagnetic switch valve 62 that nozzle 40 connects therewith, become open position.
Like this, because top nozzle 20, sidepiece nozzle 50, nozzle 40 is relative with the substantial middle portion that is difficult to cooling segment down, so can spread all over the Zone Full that this is difficult to cooling segment, but medium of blast-cold expeditiously.
As previously mentioned, only cooled off the extrded material of the part of outer peripheral face, when on discharging roller-way 14, transporting when mobile and by cooling roller bed 15, be forced to air-cooled.
When this forced cooling, because outer peripheral face roughly reduces temperature equably, it is uneven that cooling can not take place, so can not produce bending.
If the staff judges the part of outer peripheral face and does not exist under the situation of the part (that is, can roughly cool off the cross sectional shape of outer peripheral face equably) that is difficult to cool off, do not work for pre-cooled 18.At this moment, last cooling end 18a, the first sidepiece cooling end 18c, the second sidepiece cooling end 18d are in and preserve the position.
When above-mentioned extrded material transports when mobile and by cooling roller bed 15 on discharging roller-way 14, be forced to air-cooled.
When air blast cooling, because outer peripheral face roughly reduces temperature equably, it is uneven that cooling can not take place, so can not produce bending.
In the above-described embodiment, 3 top nozzles 20 are set on the direction of extrusion and right angle orientation,, top nozzle 20 are moved in the direction of extrusion and right angle orientation from the 20 ejection cooling mediums of top nozzle arbitrarily.
Equally, also can a plurality of nozzles 40 down be set, select any one nozzle 40 down, the ejection cooling medium in the direction of extrusion and right angle orientation.
In addition, also can a plurality of sidepiece nozzles 50 be set, select sidepiece nozzle 50 arbitrarily, the ejection cooling medium at above-below direction.
That is, as long as upward cooling end 18a, following cooling end 18b are just passable in the position of the direction of extrusion and the variable ejection cooling medium of right angle orientation.
As long as the first sidepiece cooling end 18c, the second sidepiece cooling end 18d can be in the positions of above-below direction change ejection cooling medium.As above-mentioned cooling medium, beyond the deacration, can utilize cooling water, empty G﹠W (spraying) etc.
Also can control the amount of the cooling medium that blows out from above-mentioned each nozzle and blow out width.For example by changing the amount of flow, supply pressure control cooling medium.
According to the present invention, the part of outer peripheral face is the extrded material of the cross sectional shape that is difficult to cool off than other parts, before forcing cooling, only carry out pre-cooled because be to its part that is difficult to cool off, temperature is reduced, carry out air blast cooling thereafter, so it is uneven can not produce cooling on outer peripheral face, when air blast cooling, can not produce bending.
Can roughly cool off the extrded material of the cross sectional shape of outer peripheral face equably, directly air blast cooling after extruding.
Therefore, the part that can make outer peripheral face is the extrded material of the cross sectional shape that is difficult to cool off than other parts, can not produce crookedly owing to air blast cooling, can not cool off.
In addition, because mainly be extrded material is carried out mandatory air-cooled, so there is no need on the extrded material conveying channel after extruder, for example be provided with on the large-area ground of discharging roller-way, cooling roller bed, the subsequent processing device of cooling medium is set.
In addition, any cooling end that can be by pre-cooled 18 cools off top, following arbitrarily a, side the side of extrded material, the opposing party's side selectively in advance.
Therefore, to the part of outer peripheral face extrded material for the cross sectional shape that is difficult to cool off than other parts, can the only pre-cooled part that it is difficult to cool off.
Carry out air blast cooling by main cooling end, can cool off the extrded material after pre-cooled and not pass through pre-cooled extrded material.
By last cooling end 18a, following cooling end 18b, when cooling medium is blown to extrded material top, following, perhaps by the first sidepiece cooling end 18c, the second sidepiece cooling end 18d, when cooling medium being blown to a side's of extrded material side, the opposing party's side, the part of the cross sectional shape that is difficult to cool off than other parts according to the part of the outer peripheral face of this extrded material or size etc. can be in the but positions of medium of the direction of extrusion and right angle orientation and above-below direction change blast-cold.
Therefore, even in the part of extrded material outer peripheral face be position, the size of the cross sectional shape that is difficult to cool off, for example under the situation that the size of the size of the direction of extrusion and right angle orientation, height is different, also cooling medium can be blown to expeditiously above it, following a, side side, the opposing party's side, carry out pre-cooled expeditiously.
Move to and preserve the position by going up cooling end 18a, the first sidepiece cooling end 18c, the second sidepiece cooling end 18d, when beginning, can not disturb with puller by extruder 10 extrusion moldings.
In addition because after extruding beginning, can on the cooling end that each puller passes through, move to cool position successively, carry out pre-cooled, so can pre-cooled as early as possible extrded material.
