Abstract
The invention discloses an injection plastic double-wall corrugated pipe, which comprises a pipe wall of which the outer wall is corrugated bulges, and is characterized in that: the inside of the corrugated bulges is coated with a hollow inner pipe. The double-wall corrugated pipe with the structure can be formed by direct injection with a mold, and the injection steel reinforced plastic double-wall corrugated pipe has the following advantages of: 1, high ring stiffness; 2, large pipe diameter up to phi 3,000 or higher; 3, high yield; 4, high production efficiency, namely high discharge efficiency when the extruded glue amount of an extruder is sufficient; 5, smooth inner wall of a pipeline compared with a winding drain pipe, and small flow friction; 6, no leakage on the pipe wall compared with the winding drain pipe; and 7, capacity of being made into flange connection.
Description
Technical field
The present invention relates to the municipal drainage facility, specifically a kind of injection plastic double-wall 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 problems of the prior art, a kind of work efficiency height is provided, ring stiffness height, injection plastic double-wall corrugated pipe and manufacture method thereof that can machining large-sized caliber.
Technological scheme of the present invention is as follows:
A kind of injection plastic double-wall corrugated pipe comprises that outer wall is the tube wall of corrugated projection, it is characterized in that the interior pipe of hollow is arranged in the internal package of corrugated projection.
Supplementary technology scheme of the present invention is as follows:
Preferably, the interior pipe of described hollow is a steel pipe.
Preferably, described interior pipe is the steel pipe of annular hollow, is connected with strut between steel pipe and steel pipe.
The flange that integrated injection molding preferably, is arranged at the injection plastic double-wall 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.
A kind of method of making above-mentioned bellows may further comprise the steps:
A. the internal mold that matches with the plastic double-walled corrugated pipe shape of preparation and the mould of external mold;
B. interior pipe simmering and bending are welded into toroidal, the caliber of thin walled tube is less than crest, and the bellows of diameter after the simmering and bending and desire shaping is suitable, and is welded together by support bar group between the slim interior pipe with simmering and bending;
When b. producing, will organize pipe box, and again external mold be closed merging the group pipe is embedded in the wave groove of external mold, carry out injection moulding, locked mode pressurize, and take out inside and outside mould after injection moulding is finished respectively and get final product in the internal mold outside.
The invention has the beneficial effects as follows: the double-wall corrugated pipe of this structure can adopt the direct molding and forming of mould, and the steel reinforced plastic double-wall corrugated pipe of molding and forming has following superiority:
1. ring stiffness height.
2. caliber is big, and diameter can reach φ 3000. even bigger.
3. yield rate height.
4. manufacturing efficiency height when the plastic squeeze amount of extruder is enough, goes out the tube efficiency height.
5. inner wall smooth, the current frictional resistance is little.Compare with the wrap style waste pipe, inner-walls of duct is smooth.
6. can not leak.Compare with the wrap style waste pipe, tube wall does not have the leakage shortcoming.
7. can make flange connects.
Description of drawings
The present invention will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 be injection plastic double-wall corrugated pipe embodiment of the present invention partly cut open figure;
Fig. 2 is the schematic representation of interior pipe among the injection plastic double-wall corrugated pipe embodiment of the present invention:
Fig. 3 is the external mold of processing injection plastic double-wall corrugated pipe of the present invention;
Fig. 4 is the internal mold of processing injection plastic double-wall corrugated pipe of the present invention.
Embodiment
Specific embodiments of the invention, as shown in Figure 1, a kind of injection plastic double-wall corrugated pipe comprises that outer wall is the tube wall of corrugated projection 3, different with the bellows of existing extruding and moulding, the bellows 1 of present embodiment has the interior pipe 4 of hollow in the internal package of corrugated projection 3.Because the ring stiffness height of steel pipe, and easy processing, a kind of relatively good method is directly to use steel pipe as interior pipe 4.
4 one kinds of preferred modes of above-mentioned interior pipe are to select the steel pipe of annular hollow for use, and are convenient for whole bellows injection molded, are connected with strut 5 between steel pipe and steel pipe.Above-mentioned interior pipe 4 also can select for use the steel pipe of screw type as interior pipe 4.
Injection plastic double-wall corrugated pipe manufacture method of the present invention is:
The mould of preparation internal mold 7 and external mold 6, as shown in Figure 3 and Figure 4.With thin-walled, be welded into toroidal as wall thickness 1mm or 4 simmering and bending of thinner interior pipe, the caliber of thin walled tube is smaller than crest, and the bellows of diameter after the simmering and bending and desire shaping is suitable, the slim interior pipe assembly welding of simmering and bending is become the shape (abbreviation group pipe) of Fig. 2.During production, will organize pipe box, and again external mold 6 be closed merging the group pipe is embedded in the wave groove of external mold in internal mold 7 outsides.The plastic emitting that is equipped with extruder and injection machine on external mold is chewed, and the quantity of extruder depends on caliber (plastic squeeze amount).Injection machine mainly is to be used for the locked mode pressurize.Taking out inside and outside mould after injection moulding is finished respectively gets final product.
For injection plastic double-wall corrugated pipe directly easy to connect with pipe, can be in the injection moulding course of working at the bellows two ends integrated injection molding flange 2 respectively.
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
