Description
The invention relates at metal tube surfaces externally and internally covering resin with the process of manufacturing multiple tube and the improvement method of process units; Composite pipe production method and the relative assembly just invented through improving in order to cover resin with various character.Surfaces externally and internally at metal tube covers the resin that one deck has certain characteristic, makes multiple tube, is mainly used in warm water and cold water pipes.Its preparation method is as follows: for the inner surface covering resin at narrow tube, earlier the resin that covers in the pipe is made into tubulose, makes and the forming metal pipe to the periphery of pitch tube then, last outer race crust at metal tube.
This multiple tube producing device and preparation method are represented by Figure 12 artwork.Figure 13 structure chart and Figure 14 structure chart are publication 99-6415 numbers.Concrete manufacturing process is as follows: by extruding (extrusion) machine moulding and twist in the interior plastic tube (51) on the wheel and the metal tape (531) that twists on the wheel is sent to the metal tube make-up machine, this process is realized by feeding mechanism (142).The metal tape (531) that feeding mechanism (42) is supplied with encases the inside plastic tube of being supplied with by mould (34) (51) and forms metal tube (53), and this process is realized by metal tube shaped device (143); For metal tube shaped device (143) can be made metal tube (53), use two end faces of bonding machine weld metal band (531), this is realized by welder (144); The be locked outer surface of interior plastic tube (51) of the metal tube (53) of burn-oning for welder (144) draws metal tube, makes its extension, thereby can pass through axle sleeve hole, and this is realized by metal tube initiating device (15 ').Through the metal tube (53) of metal tube initiating device (15 ') the moulding interior plastic tube (51) that is elongated and is locked, at this moment metal tube (53) is peripheral form again by extruder outside plastic tube (54), these are characteristics of this multiple tube producing device.
By extruding (extrusions) machine moulding and twist in the interior plastic tube (51) on the wheel and the metal tape (531) that twists on the wheel is sent to the metal tube make-up machine, this is supply stage (142) realization.The metal tape (531) that feeding mechanism (42) is supplied with encases the inside plastic tube of being supplied with by mould (34) (51) and forms metal tube (53), and this is metal tube formative stage (143); For metal tube shaped device (143) can be made metal tube (53), use two end faces of bonding machine weld metal band (531), this is welding stage (144); The be locked outer surface of interior plastic tube (51) of the metal tube (53) of burn-oning for welder (144) draws metal tube, makes its extension, thereby can the channel axis trepanning, and this is by metal tube initiating device (15 ').Through the metal tube (53) of metal tube initiating device (15 ') the moulding interior plastic tube (51) that is elongated and is locked, at this moment metal tube (53) is peripheral form again by extruder outside plastic tube (54), these are this multiple tube preparation methods.
Therefore, interior pitch tube (51) is by interior pipe forming apparatus (111) extrusion modling, and by cooling device (112) and initiating device (113) typing, supply to next process (141) by winding wheel (55) afterwards, meanwhile the utilization of the mould (34) of metal tube shaped device (143) twists in the thin plate (531 on the wheel; Metal tape) clamps interior plastic tube and form pipe, weld by welder (144) then.Because of lamella thickness little, technically be difficult to realize butt welding (Butt welding), so two cross sections are carried on the arm weld (Wrap welding) again after connecing certain width, at this moment metal tube (53) has just entangled interior pipe (51), but the two is not bonded together.At next process, to pass through metal tube initiating device (15 ') drawing metal tube (53), dwindle the diameter of metal tube, the outer surface of interior pipe (51) and the inner surface of metal tube are locked, utilize the adhesive (52) that spreads upon inner tube outer surface bonding again, cover outer tube (54) by outer pipe forming apparatus (161) in the periphery of metal tube afterwards, finish multiple tube; By multiple tube devices for taking-up (162), batch multiple tube (5) then, finally finish product by winding wheel (55).
As the device of realizing said process, interior pipe (51) is by extruder (omitting diagram) extrusion modling, be sent to next process with wheel, thin plate (153) is also on wheel, material is supplied with in rotation by two wheels, metal tube shaped device (143) shown in Figure 13 utilizes the bunseam welding, and (the distribution workshop practictice heard in blue or green literary composition, on January 15th, 82,175 pages) formation metal tube (53), again the metal tube of moulding (53) is welded with common bonding machine (peripheral solder of thin plate is used the alternating-current resistance welding usually), use initiating device shown in Figure 14 (113) drawing metal tube (53) again, pipe and metal tube in bonding are afterwards at the peripheral outer tube (54) that covers of metal tube (53).But said method and device have following shortcoming (because of not having technical difference between " device invention " and " the method invention ", so two kinds of inventions are described together).In the middle of the interior pipe moulding process, interior pipe forming apparatus (111, extruder extruding) and cooling device (112) and initiating device (113) all be common unit, interior pipe is made the back and is twisted in wheel by devices for taking-up (114), therefore (51) length of pipe is subjected to the restriction of wheel specification size in, so whole technology can not be implemented in linearize (online), process efficiency is low.As the shaped device (143) of metal tube, bunseam welding as shown in figure 12 when rolling up thin plate (531) tubulation continuously, needs only between numerous wheels even the generation fine error will generate useless pipe.Repair the required operation of these errors and depend on professional's technical ability, be restricted so produce in batches, especially the thin plate of Gong Geiing (531) approaches not only but also narrow, and longer, easily shakes during supply, and this will cause serious problem when tubulation.For pipe and metal tube (53) in bonding, need drawing metal tube (53), if the inner materials of metal tube (53) is inhomogeneous, the extension degree of each several part is different so, and is bonding also inhomogeneous.Metal tube (53) is by welded seal, because the percentage elongation at welding position and other position is different when thermal deformation, some bubbles so often mix between interior pipe (51) and the metal tube (53), especially not butt joint (bun) but carry on the arm under the state that meets (wrap) in the thin plate close mouth, the inner surface of metal tube (53) must have offset, percentage elongation is also different, so the generation of waste product is unavoidable.Other device, since too general, so can light produce multiple tube (5) with these equipment, also be suspicious thing, so those equipment omit at this.

The present invention who forms by above-mentioned part, the C part enlarged drawing of borrowing finished product state figure-Figure 10 of the present invention and Figure 10 just Figure 11 further specifies as follows:
According to flowage structure of the present invention, as the compound pipe molding Process, concrete technology is as follows: interior pipe moulding process (11)-and the mould of the resin of fusion through the lattice of establishing rules, pipe (51) in cooling forms; The above-mentioned interior pipe of coating technique (12)-preheating (51) is also smeared adhesive (52) in the periphery and is cooled off; Metal tube moulding process (14)-above-mentioned interior pipe and aluminium sheet supply to forming supporter (3) together, become the tube that includes interior pipe (51), and welding; Joint technology (15)-the sticking platform of pipe (51) and outer tube (53) in above-mentioned; Outer tube manufacturing process (16)-smear adhesive (52) at above-mentioned metal tube (53) outer surface through extruding, heating, cooling outer tube (54), is enclosed within the metal tube afterwards.It more than is basic technology; Coating technique (12) and metal tube moulding process (14) and outer tube manufacturing process (16) are added afterwards again and are drawn taking technique (13) in addition, and it gets device (2 by drawing of constituting of a pair of belt (23) that rotates at the same rate up and down; Haul-offM/C) realize; Above-mentioned technology and publication 99-6415 Process-pipe (51) twists in winding wheel (55) afterwards in making separately, compare by a dead lift next process, because of it streamline (online) as basic, so the minimum streamline length that needs 183m.And smooth and easy in technology, and the place that can avoid conflicting with other technology is appended and is drawn taking technique (13).Its structure is as follows: can draw raw material after interior pipe (51) and metal tube (53) and outer tube (54) moulding, help moulding.The taking technique (13) that draws of the present invention adopts by drawing of forming of a pair of belt (23) up and down and gets device (2), prevents to be drawn by driving wheel the outside cut of generation when getting.
Another kind of structure of the present invention is curve metallization processes (17), exactly hoop (171:hoop unit) is the pipe of last procedure rotate to an angle (Round).Before the needed welder of metal tube moulding process (14), adding technology as mentioned above, length is completely wanted 180m at least, so old technology is cut apart whole technology, pipe (51) in making in addition.But the present invention is implemented in linearize (online), has improved process efficiency, and in order rationally to arrange Facility Layout (layout), curve metallization processes (17) has been added in the centre, makes processing line furnish into broken line type from linear pattern.Can occur the temperature distortion after metal tube (53) has welded, curve metallization processes (17) is arranged in welder can prevent to produce more changeable shape before.Hoop (hoop unit) (171) is that the pipe (51,53) that straight line transmits is rotated 180 degree devices with decided diameter.For example, the periphery of major diameter circle wheel (wheel) make can guiding pipe (53) chase, steadily rotate respectively with this and to manage; Perhaps the wheel of many minor diameters is arranged to large diameter circumference, drives pipe (53) by these many steamboats and rotate gradually.
In multiple tube manufacturing installation structure of the present invention, the resin of dissolving, the mould of passage certain specification form interior pipe (51) and adjust to given size (Sizing) and cool off afterwards, and this is interior pipe manufacturing apparatus.Pipe (51) in the glue spreading apparatus preheating is smeared adhesive (52) and cooling.The material feeding mechanism batches thin plate (531), and with the interior pipe of certain tension force supply (51) and thin plate (531), shaped device is accepted thin plate (531) and the interior pipe (51) that supply is come, and is rolled onto metal tube (53).The metal tube of high-frequency welding equipment welding fabrication (53), metal tube on the engagement device seam welding (53) and interior pipe (5), glue spreading apparatus is smeared adhesive (52) and cooling to the periphery of metal tube (53), and outer pipe manufacturing apparatus is in the outer race upper exterior tube (54) and the cooling of metal tube (53).Above device is a basic device.In the streamline (Line) that constitutes by above device, draw in adhesive (52), shaping jig (3) and the increase of outer pipe manufacturing apparatus back and to get device (2).By motor-driven pair of driving wheels (21 up and down, 21) put belt (23,23), this driving wheel (21), follower (22) and belt (23) are by the cylinder that is installed in top (Cylinder) (25,25) adjust up and down, this drawing gets device (2) and can adjust the component locations that moves between each device.The up and down a pair of belt of being made by rubber (23,23) is enclosed within on the driving wheel (21) and follower (22) of motor (not have expression among the figure) driving, with same direction with fast transfer member, so transfer tube (51 lightly as sectional drawing 4,53,54), do not stay cut.On wheel of upside (21,22) and the belt (23) a pair of cylinder (Cylinder) (25,25) has been installed, wheel and belt are up and down according to part dimension, keep suitable distance between the parts.Follower (22,22) go up installation tension adjusting device (24,24), be exactly rotary handle (242), passive wheel shaft (241) advances or retreats, follower (22,22) and transfer distance variableization between the wheel (21,21), belt (23,23) tension force, thus the parts periphery neither stay draw subcutaneous ulcer again can (Sleep) out of hand.Up and down belt (23,23) must with parts on contact and could pass parts, as shown in Figure 4, this moment, belt contained the parts periphery a little.Belt (23,23) when retreating the wheel (21,21,22,22) under the belt do not support after the middle part, could flexibly pass parts.For addressing this problem, just as shown in Figure 4, disconnect after the middle part of wheel (21,21,22,22) that just connect with axle can better solution, the belt of narrating after just being to use (23,23).Even such design variations is arranged, it still belongs within the technology of the present invention thought range, obviously is the thing within the scope of authority.
In the structure of apparatus of the present invention, drawing the belt (23,23) of getting device (2) has certain thickness, and in the middle of it porose (231), thereby the parts on the pipe (51,53,54) can not stayed cut even press yet.
In the middle of the present invention's one multiple tube manufacturing installation, as shaped device, arranging most anchor clamps (3) by certain distance, it is firm on fixture stand (31) by last two bed dies (32,34), and can move up and down, thereby easy to adjust.The support ditch (33) that passes through for interior pipe (51) is arranged on the last side mold (32), and following side mold (34) has forming through hole (35), thereby thin plate can be rolled onto on the pipe in order.Following side mold in the anchor clamps (3) (34,34 ...) on forming through hole (35) is arranged, make thin plate form circle gradually from linear state.The thin plate (531) that is fed to first forming through hole (35) is a linear state, and it just forms circle during by last forming through hole (35), and be hidden within the interior pipe (51) of last side mold (32) inside the metal tube (53) this moment.In the former invention, with anchor clamps of the present invention (3) difference, use Butt seam welding, thereby most wheel is pressed into pipe to thin plate, but this way is difficult to adjust the wheel spacing, thin plate (531) thickness is little, and breadth is narrow, when mobile owing to own wt trembles.Move also vibration easily of pipe (51) in the resin of coming in addition simultaneously, and this vibration becomes a deadly defect.Pipe (51) and thin plate (531) in the anchor clamps (3) of current invention support respectively and move, thus above problem can not take place.Even the thin plate that used thickness is little (531), two ends can be not overlapping in moving for thin plate, makes pipe under the state that is close to, and the multiple tube of Zhi Zaoing (5) size is correct in this way, can overlap upper thin sheet fully.
Another structure of apparatus of the present invention is exactly to go up lower whorl engagement device (4).It by self-rotation wheel (42) and on take turns (43) and form.There is semi-circular chase (421) centre of self-rotation wheel, can go up rotation at forming supporter (41).In the middle of the last wheel semi-circular chase (431) is arranged also, when it was docked to the top of self-rotation wheel (42), two chases (421,431) formed just round, can move up and down on forming supporter (41).Metal tube (53) move to by self-rotation wheel (42) and on when taking turns (43) formed chase (421,431) diameter diminish, thereby the inner face of metal tube (53) is close to interior pipe (51) periphery, and adhesive (52) has been coated in interior pipe periphery (51), and pipe (51) firmly sticks in the metal tube (53) in guaranteeing.The invention in past is dwindled the diameter of metal tube (53) with fashion of extrusion, but because the thermal field that welding is produced, material can not evenly extend, and causes the bond quality problem.The present invention utilizes a pair of wheel the (42,43) to carry out local diameter to dwindle operation, so above-mentioned defective can not take place.In addition, the axle (47) that can control the last wheel of rotation (43) is installed on the shelf (41), and when rotation was installed in the handle (45) on shelf (41) top, Handle axis (46) can move up and down axle (47), and it equals " gear and pinion (Rack; Pinion) " principle.
One of apparatus of the present invention are exactly left and right wheels engagement device (4).It is made up of a pair of left and right wheels (44,44), and semi-circular chase (431, the 431) butt joint in the middle of the wheel forms just round, goes up rotation at shaping frame (41), and can about adjust, it is similar to catch up with lower whorl engagement device (4), role also is the same.
One of apparatus of the present invention are exactly above last lower whorl engagement device (4) of a cover and above left and right wheels engagement device (the 4 ') cross arrangement of a cover.When metal tube (53) passed through the chase (421,431,441) of each wheel (42,43,44), diameter diminished gradually.Because last lower whorl engagement device (4) and left and right wheels engagement device (4 ') cross arrangement, metal tube (53) dwindles gradually, reaches the purpose of pipe (51) in the fluid-tight engagement.The engagement device (4,4 ') that uses is many more, and diameter diminishes more gradually, but considers from economic angle, and the device about three covers can be raised the efficiency and economy simultaneously.
