Description
Technical field:
The utility model is relevant with plunger air insulation, special be used in to press outer sizing method to extrude the plunger air insulation device of production plastic pipe relevant.
Background technology:
Referring to Fig. 1, traditional when producing plastic conduit with the outer sizing method of inner pressed, there is gas circuit to communicate in the core rod with compressed air, the plastics embryonic tube of extruding from mouth mould 2, core 14 enters in the outer sizing tube 3 of water flowing cooling, need this moment envelope gas column plug 5 to cooperate, the gases of pipe in 4 are kept certain pressure, make still unshaped pipe 4 under air pressure, be close to the outer sizing of outer sizing tube 3 realization tubing, to satisfy the requirement of tube outer diameter dimensional accuracy height, smooth outer surface.Common envelope gas column plug is fixing by the stay cord 6 that an end is fixed on the core 1, because the position of envelope gas column plug just can not influence the inner wall surface quality after should being chosen in plastic tube inwall cooling section, thereby pull rope often is difficult to operation than length, often can't adopt the method operation because of the inner space is too little for small dimension especially, so abandoning this scheme more, adopts the small dimension pipe method in the pipe end shutoff, but in occurring, this scheme presses leakage situation when tubing cuts, avoid occurring leaking then needing to form new plug at each cut point flattening tubing, pressure before and after isolating, but can occur the useless pipe of certain-length at each cut point, cause waste.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of simple in structure, uses easy to operately, and envelope gas is effective, presses outer sizing method to extrude the plunger air insulation device of production plastic pipe in being used for.
The purpose of this utility model is achieved like this:
Pressing outer sizing method to extrude the plunger air insulation device of producing plastic pipe in the utility model is used for has and is positioned at plastic pipe wall at least one group of magnetic outer shroud or steel loop outward, be positioned at least one group of magnetic magnetic envelope gas column plug or the steel column plug opposite of plastic pipe wall with the magnetic outer shroud, magnetic all is installed (if S utmost point magnetic is installed in the tubing wall inside and outside the plastic pipe wall, then the tubing wall is installed N utmost point magnetic outward, so that by the mutual absorption affinity in the two poles of the earth the envelope gas column plug of installing in the tubing wall is fixed the position), can increase magnetic force, if on tubing wall internal and external circumference, evenly distribute several groups of magnetics, can make the envelope gas column plug suspension of installing in the tubing wall and fix the position, envelope gas better effects if.Gas in the tubing is kept certain pressure, make still unshaped tubing under air pressure, be close to outside the sizing tube inner surface realize the outer sizing of tubing, to satisfy tube outer diameter dimensional accuracy height, the requirement of smooth outer surface, simultaneously, the tubing production that those internal diameters are had relatively high expectations, because envelope gas column plug maintains static, smooth in appearance, be placed in the pipe production line appropriate location, can replace traditional baroque, connect together with die head, jib-length is subjected to the interior sizing plug of tubing of structural limitations, internal surface of pipe is carried out sizing processing, or work with traditional interior sizing plug one, lay many group envelope gas column plugs, internal surface of pipe is carried out accurate sizing processing, make internal surface of pipe more smooth.Internally through the sizing pipe that has certain requirements, often because of the interior core of extrusion die and in cooling sizing plug can not be oversize (oversize internal resistance is too big, it is too big to rub, the cantilever support distortion is big, tubing easily traction is disconnected) and influence line speed and efficient, therefore need with tubing pull out when further tubing being cooled off, have behind the cooling sizing plug in sizing tool pipe internal diameter is had sizing effect again, the envelope gas column plug of magnetic attraction is exactly well interior sizing tool, and can increase envelope gas column plug group number, reduce friction, strengthen the sizing effect, can improve line speed and efficient.
At least contain a permanent magnetism gonosome or electromagnetism gonosome in above-mentioned magnetic outer shroud or the magnetic envelope gas column plug, the electromagnetism gonosome will connect power supply, but magnetic force is big and reliable, and the permanent magnetism body structure is simple.
The above-mentioned at least one group of magnetic that is positioned at the plastic pipe wall seals the gas column plug or the steel column plug is the hollow-core construction of weight reduction, so that envelope gas column plug just can be fixed the position with less magnetic force.
The above-mentioned at least one group of magnetic that is positioned at the plastic pipe wall seals the gas column plug or steel column is plugged with the little polymeric seal circle of temperature resistant rubber or heatproof and smooth surface coefficient of friction, to increase gas sealing ability.
Above-mentioned be positioned at least one group of outer magnetic outer shroud of plastic pipe wall or steel loop has the combined type Kraft structure of being convenient to open loading and unloading.
The frame of being convenient to mobile installation site is arranged in the above-mentioned device, and magnetic outer shroud or steel loop are loaded on the frame.
The utility model can be placed in the different position of pipe production line according to the situation of producing different tubing, as be placed in before or after vacuum box of pipe production line or the cooling water tank or among.
The utility model be used for the outer sizing method of inner pressed produce the sealing device of plastic conduit changed traditional envelope gas column plug need be from the mode of operation of core stationary rope traction, and by the magnetic outer shroud that is positioned over the pipeline outside and be positioned over magnetic attraction location between the envelope gas column plug of the carrying magnetic material in the pipeline, make envelope gas column plug in the pipeline rely on the effect of magnetic force can bear and keep in the sizing gas pressure, make still unshaped tubing under air pressure, be close to the outer sizing processing of outer sizing tube inner surface realization tubing.Envelope gas column plug carries out sizing processing to tubing, to satisfy the high and inside and outside ganoid requirement of the inside and outside footpath of tubing dimensional accuracy.Not only simple in structure, easy for operation, and gas sealing ability is good, envelope gas effect is good, is fit to the production of all size pipeline, and particularly the production of small dimension pipe is more effective.
