The utility model provides a production device for steel-plastic composite pipe with two layers of polymer, comprising a steel plate or a steel wire reel releasing mechanism, formation welding mechanism or welding formation mechanism, polymer formation pipe wall wrapping frame, extrusion mechanism of composite polymer formed on the pipe wall, inner layer extrusion machine and/or outer layer extrusion machine, cooling formation box and towing machine. The utility model is characterized in that a squeezing and molding mechanism, which can force the fusing polymer with the Mould-Head and the interval channel through cylindrical frame, and can wrap the frame into the tube wall at the periphery of the metallic frame and/or the inner cavity as well as a squeezing and molding mechanism, which can force out the fusing polymer with the Mould-Head and the interval channel without passing through the cylindrical frame. The polymer has been in shape both in the outer and inside of the tube wall. The composite tubes whereby produced have outstanding bearing capacity and the plastic tube wall and the metallic frame are fast compounded.
Description
Technical field:
The utility model relates to a kind of steel-plastic composite pipe process units, what be particularly related to is that the molten polymer that a kind of extruder is extruded passes the clad tube wall that pertusate tubular metal frame forms metal frame, extrudes the process units of the skin (or internal layer) that is compounded to form steel-plastic composite pipe again.
Background technique:
Existing with pertusate metal frame do enhancing body, extrude composite polymeric materials and mainly contain three kinds of forms as the method and apparatus that continuum becomes the skeleton coating production technology of steel-plastic composite pipe on this skeleton: first kind as B. P. GB2255,148A92.10.28, Chinese patent application numbers 99112221.6,99232026.7, these disclosed technological schemes are that steel plate with hole with holes is through being curled into cartridge type longitudinally and being welded as the cartridge type metal frame, metal frame is pushed or draws in the compound die head of the polymer that molten plastic runner and forming cavity are arranged or forming cavity mould that is connected with plastic extruder, the hole that the polymer continuum of fusion passes metal frame forms the internal and external layer tube wall simultaneously at the inner and outer surface of metal frame skeleton is coated, pass through cooling and shaping, just produced the composite metal plastic pipe that metal frame strengthens the tube wall that is coated with metal frame; Second kind as patent 94104509.9, the broadwise steel wire twines steel radial through the steel wire tubular metal frame that is welded, stretch into the polymer that the extrusion die in the steel wire tubular metal frame of welding fabrication is extruded, the hole that passes metal frame forms the internal and external layer tube wall simultaneously at the inner and outer surface of metal frame and skeleton is coated forms composite metal plastic pipe; The third is 200510022044.5 as number of patent application, and molten mass does not pass the hole of metal frame and extrudes compound sandwich layer pipe at inner wall of metal tube, extrudes the composition polymer external pipe in the appearance of metal frame again.But the hole that passes metal frame by the polymer continuum that the technological scheme in the above-mentioned several patents is fusion forms the internal and external layer tube wall simultaneously, there is very big defective in this molding mode, the polymer continuum of fusion is translated into the mutual again adhere of another side at the hole that passes metal frame, the Turbulence Flow mode that this polymer is crossed metal frame can stay a lot of residual stresss in cooled plastic tube wall, cause in the pipeline using process easy to crack, reduced the working life of pipeline, and this type of flow can be destroyed and extrude compound or spraying or cover the particularly very thin one deck adhesive layer in the hole of metal frame inner and outer surface, cause polymer continuum and metal frame surface directly to combine rather than be combined with each other securely each other by adhesive layer, and the polymer continuum is an apolar surfaces, the metal frame surface is a polar surfaces, the two can not be real mutual strong bonded, cause in transportation or installation or delamination mutually in using, in addition, the mutual adhere face of polymer causes temperature to descend to some extent owing to cross metal frame, has also influenced the reliability and the intensity of mutual adhere.In order to improve metal frame and polymer is combined closely mutually, the applicant applied for 03117307.1＜at the continuous process units of steel-plastic composite pipe that hole Steel Skeleton inner and outer surface application Bond is arranged〉and patent, before extruding composition polymer mechanism the Bond applying mechanism that can all adhere to Bond by the hole of tubular Steel Skeleton at the Steel Skeleton inner and outer surface is simultaneously arranged, promptly earlier the hole of Bond by the tubular Steel Skeleton adhered at the Steel Skeleton inner and outer surface, again polymer-extruded hole by the tubular Steel Skeleton is formed interior outer plastic layer at the Steel Skeleton inner and outer surface, the manufacture method that this Bond and polymer all will pass the hole of tubular Steel Skeleton has a shortcoming, be that polymer is when passing the hole of tubular Steel Skeleton, can will stick to the lip-deep Bond of Steel Skeleton washes away, polymer is directly contacted with the Steel Skeleton surface again, Bond does not play a role, the mutual strong bonded that polymer and Steel Skeleton surface can not be real.
The model utility content:
