Abstract
The invention discloses an enhanced plastic double-walled corrugated pipe, comprising a pipe wall with an outer wall to be corrugated and convex. The enhanced plastic double-walled corrugated pipe ischaracterized in that an annular and hollow inner pipe is packed in the corrugated and convex inside. The invention has the advantages that the plastic double-walled corrugated pipe with the structurehas high ring stiffness, high yield, simple operation, high production efficiency, smother inner wall and little water flow friction, the manufacturable pipe has a diameter as large as 3,000 or more,and the structure can be made into the flanged connection. The manufacturing method of the invention uses the flame for heating the molds, thereby saving the electric energy and lowering the manufacturing cost.
Description
Technical field
The present invention relates to plastic ripple pipeline and manufacture method thereof, especially a kind of enhanced plastic double-walled corrugated pipe and manufacture method thereof.
Background technique
Common extrusion type plastic double-walled corrugated pipe shortcoming is: 1, be subjected to the restriction of extruder head, diameter can not be done very greatly, generally is difficult to exceed φ 1200; 2, ring stiffness is not enough, and pure plastic double-walled corrugated pipe ring stiffness is usually less than SN8, and Ministry of Construction's regulation waste pipe ring stiffness can not be lower than SN8; 3, yield rate is lower, and especially major diameter is produced relatively difficulty such as φ more than 800, and yield rate is low.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of fabricating cost is lower, ring stiffness is high enhanced plastic double-walled corrugated pipe and manufacture method and mould are provided.
Technological scheme of the present invention is as follows:
A kind of enhanced plastic double-walled corrugated pipe comprises that outer wall is the tube wall of corrugated projection, it is characterized in that the interior pipe of the hollow of ring-type is arranged in the internal package of corrugated projection.
A kind of enhanced plastic double-walled corrugated pipe and manufacture method thereof may further comprise the steps:
The external mold that preparation and double-wall corrugated tube shape match, the inwall of external mold is identical with processed pipe pipeline outer wall shape;
Interior pipe simmering and bending are welded into toroidal, its caliber is less than crest, the bellows diameter of diameter after the simmering and bending and desire shaping is suitable, with welded together between the interior pipe of simmering and bending by support bar group, winding plastic band on the interior pipe that assembly welding is good, the thickness of plastic tape is identical to the distance at bellows crest top with interior pipe top, then interior pipe is put into external mold, establish shutoff at the external mold two ends, and on external mold, be provided with charging hole, plastic raw material is added die cavity;
Use flame that mould is heated and rotary die, the tube wall that plastic raw material fusing back forms bellows is wrapped in interior pipe in the tube wall;
Behind the cooling die, take out double-wall corrugated pipe.
Supplementary technology scheme of the present invention is as follows:
Preferably, the interior pipe of described hollow is a steel pipe.
Preferably, between steel pipe and steel pipe, be connected with strut.
The flange that integrated injection molding preferably, is arranged at the enhanced plastic double-walled corrugated pipe two ends.
Preferably, the sealability in order to connect between the pipe end has the circular groove that seal ring is installed on the exterior edge face of at least one flange.
Preferably, described external mold is that level is horizontal, in both mold ends the support roller supporting mould is arranged.
Preferably, described external mold is vertical setting, is axially arranged with supporting wheel along mould, and supporting wheel contacts with the mould outer wall.
The invention has the beneficial effects as follows: the plastic double-walled corrugated pipe ring stiffness height of this structure, the caliber that can make is big, and diameter can reach φ 3000. even bigger; The yield rate height; Simple to operate, the manufacturing efficiency height; Inner wall smooth, the current frictional resistance is little; Can make flange connects.Manufacture method of the present invention adopts flame to mold heated, has saved electric energy, has reduced manufacture cost.
