Abstract
The invention relates to a corrugated pipe comprising elastic skeletons and a manufacturing method for the corrugated pipe comprising the elastic skeletons. By the aid of the corrugated pipe comprising the elastic skeletons and the manufacturing method for the corrugated pipe comprising the elastic skeletons, the strength of the corrugated pipe with a large aperture can be effectively improved, and elasticity of the corrugated pipe with the large aperture can be fundamentally improved. The corrugated pipe comprising the elastic skeletons comprises a corrugated pipe body. The skeletons of reinforced ribs are spirally wound on the corrugated pipe body and consist of elastic plastic cores and steel wire meshes wrapped on the elastic plastic cores, and plastic layers are wrapped on the steel wire meshes. The corrugated pipe comprising the elastic skeletons and the manufacturing method for the corrugated pipe comprising the elastic skeletons have the advantages that with the design of the elastic skeletons, overall compressive strength and bearing strength of the corrugate pipe are greatly improved, expansion changes of the corrugated pipe due to temperature are restrained to the maximum extent, and adaptability of the corrugated pipe to different temperatures is further enhanced, so that disconnection of connecting joints of the manufactured corrugated pipe and fluid leakage are avoided.
Description
Technical field
The present invention relates to one and effectively can not only improve heavy caliber bellows intensity, and the elasticity of heavy caliber bellows can be made to obtain a kind of bellows of being made up of elastic skeleton that essence improves and making method, belong to bellows and manufacture field.
Background technique
CN201078525Y, title " steel strip enhancement polythene helical bellows of spigot-and-socket electric melting connecting type ", it is for solving the problem of the easy seepage of steel band reinforced polyethylene spiral ripple pipe connection interface and poor reliability.Steel strip enhancement polythene helical bellows of spigot-and-socket electric melting connecting type, with outer layer polyethylene, the metal frame of winding is fixed on inner layer polyethylene, particularly one end of bellows is provided with socket, and the other end of bellows is provided with bellmouth, bellmouth inwall is imbedded a circle electric heating element composition.Adopt this steel strip enhancement polythene helical bellows of spigot-and-socket electric melting connecting type, can be widely used in the connection construction of plastic tube.Its deficiency: one is metal frame is take off structure outward, what formed with inner layer polyethylene is that line face contacts, instead of face contact, not only plyability is poor, and under the effect of external force, metal frame is easily outer takes off movement, causes and destroys inner layer polyethylene, the quality of direct shadow pipe matter, even causes inner layer polyethylene damaged; Two is that support strength is low, and because metal frame is in taking off structure outward, its metal frame both sides outwards movement of external pressure, not only causes the layering of metal frame and inner layer polyethylene, and cause the direct reduction of inner layer polyethylene intensity; Three is due to the outer layer polyethylene material different from two kinds, metal frame system, by temperature to affect its coefficient expanded with heat and contract with cold different, therefore in use inevitably stratification occurs, cause bellows intensity sharply to decline, bellows caves in.
Summary of the invention
Purpose of design: avoid the deficiency in background technique, design one can not only improve heavy caliber bellows intensity effectively, and the elasticity of heavy caliber bellows can be made to obtain a kind of bellows of being made up of elastic skeleton that essence improves and making method.
Design proposal: in order to realize above-mentioned purpose of design.The present invention is in structural design, and in stiffening rib, the design of skeleton steel wire on elastomeric plastics core by elastomeric plastics core and cladding, is technical characteristics of the present invention.The object done like this is: because elastomeric plastics core adopts macromolecular material to form, it not only has good toughness and elasticity, and parcel steel wire thereon had both served the protective action of elastomeric plastics core, serve again the effect of stiffening rib, the plastic layer be wrapped on steel wire and plastics plug can either be organically combined into one by effectively, effectively can improve again adhesive strength between the two, when molten plastic and elastic skeleton compound tense, plastics and the welding of bellows tube wall of its melting are one, the intensity of bellows pipe shaft is made to obtain the raising of essence.
Technological scheme 1: a kind of bellows be made up of elastic skeleton, it comprises bellows, and helical disk is entangled in skeleton in bellows stiffening rib with it, and by elastomeric plastics core and cladding, the steel wire on elastomeric plastics core is formed, and steel wire wraps up plastic layer.
Technological scheme 2: a kind of making method of the bellows be made up of elastic skeleton, plastic extruder is adopted to make elastomeric plastics core, then by steel wire winding of single layer on elastomeric plastics core, then to adopt heavy caliber polyolefin manufactured by claimant to be wound around to increase pipe production line in making bellows in pipe process, while make pipe in bellows, while the elastomeric plastics core with steel wire is wrapped on bellows, while molten plastic layer is compounded on the elastomeric plastics core with steel wire by the heavy caliber polyolefin winding growth pipe production line of finally employing manufactured by claimant, steel wire heating power makes the face melting of elastomeric plastics core and combines together with pipe in molten plastic layer and bellows.
The present invention is compared with background technique, the design of elastic skeleton, not only drastically increase the entire compression of bellows, bearing strength, and the extending amount change constraining temperature to cause bellows to greatest extent, make the adaptability of bellows to different temperatures obtain further raising, thus avoid the generation that made bellows joint is thrown off, fluid runs leakage phenomenon.
