Abstract
The utility model provides a pipe material with secondary coiling and double structure. The basic structure of this utility model comprises that: the heavy caliber pipe material shaped by coiling and bonding the heated plastic band basic layer around the core pipe of mould; a layer of waveform pipe is coiled and bonded around the external of the plastic band in heating. This utility model is characterized in that: the aforesaid pipe wall refers to a double waveform pipe made by coiling and coating the secondary layer of materials similar to that of the first layer of the waveform pipe with plastic band. This utility model has the advantages of: 1. because the new structure that is constituted by coiling secondary layer of material around the waveform pipe in the first layer is adopted, the circular intensity of the product is improved. Besides, after being applied to pipe materials with heavy caliber, this utility model can reduce the weight of pipe materials, decrease the number of moulds and lower down the cost with prominent advantages; 2. in changing the type of products, the extrusion mould needs not to be changed at certain scope of caliber size, thus greatly reducing the time for type changing, saving labor and resources and improving the production efficiency.
Description
Technical field
The utility model relates to a kind of enhancement mode secondary winding double structure wall pipe, belongs to plumbing large-bore plastics tubing technical field.
Background technique
At present; large-diameter plastic pipe belongs to chemical building material; be to mould Dai Gang,, to be applied to municipal drainage to mould update product for cement; remote low-pressure water delivery; mine and chemical industry draining, the making of irrigation and water conservancy irrigation and ventilation duct and pressure vessels for the chemical industry etc. are to saving the energy; reduce and pollute, the protection environment is significant.Commercially available large-diameter plastic pipe generally adopts Korea S's technology to produce, promptly extrude the rectangular thin walled tube of hollow by extruder, by the online tubing that is wound in of mould, the tubing of Sheng Chaning has following defective in this way: 1, every suit extrusion die is produced a kind of section, this section can only be used for twining the tubing of limited diameter, and ring stiffness is wayward, and ring stiffness is not enough, influences construction quality; Ring stiffness exceeds standard, and causes cost to increase; Produce various caliber series product as desire, need to prepare a lot of sections, need a lot of molds accordingly, the product cost height.2, because mould kind quantity is many, complex managementization.Especially when producing the different tube diameters product, need frequently remodel, remodel needs about one day time at every turn, causes the waste of personnel, the energy, reduces manufacturing efficiency.3, this mode is when producing big caliber product, and ring stiffness does not reach requirement, has restricted the using scope of this product.Claimant of the present invention is once in proposed a kind of coextruding heat winding structure wall pipe, the technological scheme of processing method and mould in first to file 200520024738.8.
Summary of the invention
The purpose of this utility model be provide on the basis of aforementioned application a kind of on the coated polyethylene single-wall corrugated pipe of co-extrusion the dual structure wall pipe of secondary winding corrugated pipe, form new product structure, according to equivalent wall thickness principle, increase the ring stiffness of product.
The technical solution of the utility model is achieved in that this secondary winding double structure wall pipe, its basic structure comprises the heavy caliber pipe that is twined molding bonded by plastic tape as basic unit's spiral heat on the mold core pipe, the plastic tape external heat is twined bonding one deck bellows, it is characterized in that: described tube wall is the dual bellows that is twined the coated same material of bonding by plastic tape secondary heat on the first layer bellows.
The pitch L that described secondary winding double structure wall pipe, described bellows twine at tube wall is less than bellows diameter 2D, greater than bellows diameter D.
Described secondary winding double structure wall pipe, the dual bellows diameter D1 that described tube wall twines, D2 can equate or do not wait.
The technical solution adopted in the utility model technological progress effect shows:
1, the winding of secondary heat is combined into new structure on the first layer bellows owing to adopting, and can improve the product ring stiffness, especially uses on big caliber, alleviates tubing weight, can reduce number of molds, reduces cost, and is with the obvious advantage;
When 2, product was remodeled, in certain caliber scope, extrusion die need not changed, and has significantly reduced the time of remodeling, and saved the manpower and the energy, enhanced productivity.
Description of drawings
Fig. 1 is the structural representation of secondary winding double structure wall pipe
Among the figure: 1, mold core pipe L, bellows pitch D1, D2, bellows diameter 2,3, the coated polyethylene single-wall corrugated pipe of polypropylene co-extrusion
Embodiment
The utility model secondary winding double structure wall pipe shown in Figure 1 is twined by coated polyethylene single-wall corrugated pipe 2,3 secondaries of dual polypropylene co-extrusion and is bonded in moulding on the mold core pipe 1, the pitch L that bellows twines at tube wall is less than bellows diameter 2D, greater than bellows diameter D.Diameter D1, the D2 of dual bellows can equate or not wait.
This structure can effectively improve the ring stiffness (pipeline bears the ability of external load) of pipeline, reduces number of molds, further reduces cost, and makes product specification and performance obtain expanding.
Foregoing description only proposes as a kind of enforceable technological scheme of the utility model secondary winding double structure wall pipe, not as the single restrictive condition to its structure itself.
Claims (3)
1, secondary winding double structure wall pipe, its basic structure comprises the heavy caliber pipe of being gone up spiral heat winding molding bonded by plastic tape as basic unit at mold core pipe (1), the plastic tape external heat is twined bonding one deck bellows (2), it is characterized in that: described tube wall is the dual bellows (3) that is twined the coated same material of bonding by plastic tape secondary heat on the first layer bellows.
2,, it is characterized in that pitch L that described bellows (2,3) twines at tube wall is less than bellows diameter 2D, greater than bellows diameter D according to the described secondary winding double structure of claim 1 wall pipe.
