Description
Technical field
What the present invention relates to is a kind of corrugated plastic pipe material with screw type reinforcing rib structure and preparation method thereof.
Background technique
In the sewer and various drain pipe in city, the use of various forms plastic tube is more and more.Usually do not have pressure owing in its pipe,, be provided with the existing many reports of plastic tube and the use of multi-form reinforcing rib structure in the tube wall periphery for improving the performance of its opposing extraneous pressure or impact.The plastic tube of present this structural type and corresponding preparation method can have following several: a kind of is the plastic tube that adopts direct extruding and moulding.Tool representative be double-wall corrugated pipe and ring-stiffened pipe by direct extruding and moulding, its inner wall layer is continuously smooth-going surface, outer wall layer then is respectively the waveform configuration of hollow or solid cyclic rib type structure.The axial part section structure of these two kinds of tube material and tube walls is respectively as (a) of Fig. 1 with (b).During manufacturing, the inner wall layer of this class tubing is to extrude the continuous tubing that forms by the plastics under the molten state; Outer wall layer as reinforcing rib structure, then be at the plastics of inner tube wall layer also not fully under the situation of cooling, corresponding " trough " the position welding of continuous reinforcing rib structure layer that another is had appropriate configuration form such as hollow ripple ring rib is on the outer circumferential face of tube wall.Though the reinforced structure of forms such as the hollow ripple ring rib of this outer pipe wall layer can strengthen the rigidity of tubing effectively, the price of its manufacturing equipment is very expensive, and the difficulty of applying is very big.
Another kind of type is with helically-wound shaped plastic tube.Wherein representative is double-wall pipe and helical bellows.
The manufacturing of double-wall pipe is to extrude the pipe that section is a rectangle by first extruder earlier, becomes rectangular tube behind cooling and shaping, makes this rectangular tube be spirally wound on the large cylinder that many active rotation doffers only are housed continuously regularly side by side then; Meanwhile, constantly extruded the plastic strip of fusion again by second extruder in the adjacent side gap of this rectangular tube that spiral side by side twines, and rectangular tube is produced under the situation of lateral pressure, the rectangular tube that each is adjacent is welded together mutually.Along with the continuous rotation of active doffer, promptly form continuous double wall tubing.The axial part section structure of the tube wall of this double-wall pipe as shown in Figure 2.
The manufacture method of helical bellows is similar with it, and different is, and what to be extruded by first extruder is not the rectangular tube of common shape, but respectively has the special-shaped rectangular tube of a suitable shape fin of using for mutual welding in the both sides, bottom surface.This rectangular tube that has the both sides fin is after the sizing cooling, earlier the respective sides of the adjacent fins of adjacent two rectangular tubes that will do mutual welding is not heated to molten state with flame, and then be wrapped on the large cylinder, and the adjacent fins of each adjacent two rectangular tube is overlapped mutually, and the pinch roller backing that is oppositely arranged inside and outside the warp, the both sides fin of mutual overlap joint is welded together, promptly forms continuous tube wall after the cooling.The axial part section structure of the tube wall of this helical bellows as shown in Figure 3.
By the manufacture process of above-mentioned double-wall pipe and helical bellows as can be seen, this class tubing all is at common form or the special-shaped rectangular tube that has a fin is extruded and thoroughly behind the cooling and shaping, again by double heating to molten state, make the sidewall between the adjacent rectangle pipe or the tube wall of the corresponding tubing of adjacent fin mutual welding formation.Therefore in the structural pipe wall of these tubing, by double heating and the welded seam that forms all through its whole tube wall internal and external layer.Thereby the quality of these tubing depends on the quality of formed welded seam after this double heating fully.Because these welded seams of outer room in the whole tube wall are very long (as on 500 millimeters waste pipes of diameter, the welded seam length of per 100 mitron materials can reach 5000m), in case these must cause whole tubing to lose efficacy through a certain local cracking that occurs of the welded seam of whole structural pipe wall.
As everyone knows, make the weld portion potential energy of tubing keep as far as possible with mother metal equal strength and equivalent life then be the key factor that guarantees its quality.By employing double heating mode the plastic article under two normal temperature being fused into an integral body, and will making the intensity at its welded seam place and life-span consistent with mother metal, is very high in technologic requirement.At first the control to heating-up temperature must be in a very narrow scope; Next is that the claimed range of positive pressure size that face of weld is applied is also very narrow, and pressing time is longer, and also require very long cool time to face of weld under certain positive pressure having.These conditions and requirement Chang Buneng in the process of making tubing is guaranteed.No matter be on the manufacturing process temperature, to change, still be subjected to the influence (as at winter, Xia Liangji that the very big temperature difference can be arranged usually) that ambient temperature changes, or welded seam applied the size of positive pressure and/or the variation of time etc., all the molten quality that makes seam crossing and mother metal equal strength and equivalent life there are considerable influence.Particularly in the manufacture process of above-mentioned helical bellows, for welding during to the fin heating of these abnormal shape rectangular tube both sides, what all adopt usually is to be higher than 1000 ℃ flame directly to roast.Though the flap surface fusion of flame place of arrival, high temperature also very easily causes macromolecular decomposition of plastics and chain rupture simultaneously, and the quality at its welded seam position just more is difficult to guarantee.Therefore can see these tubing in actual use and be subjected to falling in loading and unloading, transportation or work progress and bump or part when being squeezed, Chang Yi causes the welded seam position cracking of tubing, or spring-like is scattered and the phenomenon destroyed in the shape of a spiral.
Summary of the invention
At above-mentioned situation, the present invention's purpose at first provides a kind of screw type corrugated plastic pipe material of new structure form.And then another object of the present invention provides the preparation for processing to this structural type screw type corrugated plastic pipe material.
The screw type corrugated plastic pipe material of the said structural type of the present invention, its tube wall be by be the axis strip sheet material of making the spiral wrap style with its center line with each the adjacent sheet edge in its spiral circumference successively mutually overlap joint merge formed continuous solid wall pipe shape structure, be bonded on the periphery wall of tube wall in the mode that the overlap joint of cross-pressure in each adjacent sheet edge merges on the seam position, place with the outer convex rib shape reinforced structure of making same spiral winding form, thereby form the plastic tube that on the outer circumferential face of structural pipe wall, has spiral wrap style outer convex rib shape reinforced structure.
In the screw type corrugated plastic pipe material of said structure form, the said convex tendon shape reinforced structure that is engaged on the tube wall outer circumferential face can adopt multi-form structure according to use field and/or purpose needs.For example, the muscle shape reinforced structure of this evagination can be that the cross section is the structure of entity form, also can be that the cross section is the hollow closed tubular body structure of hollow rectangle, quadrilateral such as trapezoidal or other appropriate format, can also be that the cross section is the structure of suitable opening curve form.
With regard to self composition form of said various outer convex rib shape reinforced structure bodies in the said structure form tubing, it can be the structure of the identical or different unitary plastic material forms of employing and tube wall material, also can be the structure that adopts the form of composite that is made of two or more different materials.For example, can be used as this composite material structure that one of example is recommended, is that internal layer is the reinforced structure body with metallic material, the outer composite structure form that is coated with the plastic sheet layer again.Said herein reinforced structure body with metallic material, removing directly to use the metal structure of single form external, better fuse performance for making to have with plastic tube tube wall and/or its outer field coating plastic sheet layer with the bigger materials such as metal of the plastic materials nature difference of tubing, used this has the reinforced structure body of foreign materials such as metal, preferably fuses the form that the surface, position is coated with suitable plastics or other macromolecular material rete in advance accordingly at it.
The screw type corrugated plastic pipe material for preparing said structure form of the present invention can be undertaken by extrusion molding mechanism and corresponding supplementary equipment that two covers can cooperatively interact.At first, extrude successive molten shape stripe shape plastic sheet by the first extrusion molding mechanism with the respective sheets mould that can cooperate with it, and the stripe shape plastic sheet that makes this molten forms on the circumference type rotational support structural plane that adapts with required pipe diameter with each neighboring edge spiral winding type tubular form of overlap joint mutually successively, and first pressing wheel mechanism by being arranged at tube wall periphery corresponding position place by corresponding manner rolls the overlap joint edge of each adjacent sheet and makes it mutual fusion and engage and forms continuous smooth-going solid wall pipe shape structure; Then, extrude the muscle shape reinforced structure and cooling and shaping of corresponding construction by the mould of the second extrusion molding mechanism and appropriate configuration form after, make it softening through heating again, and with same spiral canoe with its cross-pressure in the overlap joint of structural each the strip plastic sheet neighboring edge of the solid wall pipe shape that still is molten fusion seam position, place, roll by second pressing wheel mechanism that has the groove structure form that adapts that is arranged at tube wall periphery corresponding position place by corresponding manner again, make on its outer circumferential face that blends into tube wall.
In above-mentioned preparation process, synchronism that rotatablely moves when fusing mutually and the reliability that fuses for the outer circumferential face that further guarantees and improve the muscle shape reinforced structure extruded by the second extrusion molding mechanism and this solid wall pipe shape structure, can adopt and make the second extrusion molding mechanism extrude and touch muscle shape reinforced structure on the tube wall outer circumferential face, repeatedly roll by a plurality of active rotation type second pressing wheel mechanisms that are arranged at tube wall periphery corresponding position place and have, itself and tube wall outer circumferential face are fused reliably mutually to reach by the continuous helical groove structure form of same spiral way setting.
As above-mentioned, according to different use fields and/or purpose needs, saidly extrude and blend into muscle shape reinforced structure on the tube wall outer circumferential face by the second extrusion molding mechanism, it can be structure with the identical or different unitary plastic material of tubing material, also can adopt and form by different materials---for example internal layer is the intensive aspect with Structural Hardware, and it is outer also to be coated with the structure of complex form material such as plastic sheet layer.When adopting the muscle shape reinforced structure body of unitary plastic material, its preparation method can directly be undertaken by above-mentioned mode.
Strengthening as the muscle shape that adopts is that above-mentioned internal layer is the intensive aspect with Structural Hardware, when being coated with the form of composite structure of plastic sheet layer again outside it, its preparation method can increase by a step on the basis of said process, promptly roll and after welding forms continuously smooth-going solid wall pipe shape structure through first pressing wheel mechanism at the molten stripe shape plastic sheet of extruding by the first extrusion molding mechanism that is overlapped to form spiral winding type tubular form with each neighboring edge mutually, the intensive aspect that earlier this is had a Structural Hardware with same spiral canoe cross-pressure behind the overlap joint fusion seam position, place at each adjacent sheet edge on this tubular structure outer circumferential face that still is molten, extrude the corresponding plastic sheet that can be coated on outside this intensive aspect by the second extrusion molding mechanism again with Structural Hardware, and roll through said second pressing wheel mechanism, this intensive aspect with Structural Hardware and the plastic sheet that is coated on its outside are fused mutually, and the outer circumferential face that makes the tubular structure of molten also has the intensive aspect of Structural Hardware with this respectively and the edge of the plastic sheet that the outside coats all fuses simultaneously mutually, forms the complex form muscle shape reinforced structure that blends into the pipe outer wall.As above-mentioned, the muscle shape reinforced structure of this kind composite material structure form equally also can be that the cross section is solid body, hollow rectangle or quadrilateral such as trapezoidal or other hollow tubular or suitable multiple structural types such as opening curve.Equally, in above-mentioned intensive aspect with Structural Hardware, except that the metallic material of direct employing single form, for making reinforced structure physical efficiency have better fusion mutually to engage performance with the tube wall of plastic tube and/or with the coating plastic sheet layer in its outside as the bigger foreign material form of nature differences such as metal, the reinforced structure body of the foreign material form that used nature differences such as this metal are bigger preferably adopts the form that is coated with plastics or other suitable macromolecular material rete at its corresponding each position, mating face in advance.
Because the structure of said structure form screw type corrugated plastic pipe material of the present invention, adopt be at first by do molten stripe shape plastic sheet that spiral twines shape with its each neighboring edge successively mutually overlap joint and by pressing wheel mechanism roll its fusion is engaged after, in fact become a seamless continuous smooth-going real wall light wall pipe structure that fuses.Because this real wall light wall pipe is to be merged mutually by the overlap joint edge of spiral sheet material under molten state, thereby can guarantee that it fuses the equal strength and the equivalent life of seam position and silver mother metal, therefore formed thus this real wall light wall pipe structure there is no essential difference with the real wall light wall pipe that is obtained by the direct extrusion way of routine.Then, by only being heated softening, also fuse mutually again with the pipe outer wall that still keeps molten state substantially so that do the fusion seam position, place that same spiral twines the outer convex rib shape reinforced structure cross-pressure adjacent overlap joint of each plastics silver edge on structural pipe wall of form.Therefore remove and to reduce the macromolecular decomposition of plastics to greatest extent, sex change such as chain rupture and influencing outside its equal strength and equivalent life that fuses position and slip mother metal and/or reinforcing rib structure and pipe wall material, simultaneously since this outer convex rib shape reinforced structure be with same spiral canoe cross-pressure and blend on the structural pipe wall by fusing of forming of each adjacent sheet overlap joint edge and stitch position, place (though its reality has become the seamless state that fuses), not only help further improving the intensity that this overlap joint melts the seam position, the more important thing is that it only is a non-main stressed seam that fuses that plays interconnect function that each structure that makes between tube wall and outer convex rib shape reinforced structure fuses seam, even therefore the sealing-off cracking appears in this a certain part that fuses seam, also unlikely leakage and the inefficacy that causes whole tubing, thereby tubing short-term and long-term reliability can have been guaranteed and improve effectively
Obviously, with reference to the ordinary skill knowledge and the customary means of related domain,, can also make the various ways that does not break away from the above-mentioned basic fundamental thought of the present invention and replace or change according to foregoing.
