Abstract
A technology for manufacturing the corrugated dual-wall polyethylene pipe includes manufacturing corrugated dual-wall polyethylene plate by use of extruder with special head and die, vacuum cooling, rolling the corrugated dual-wall polyethylene plate to become a pipe, and heating while pressing to fuse the lapped part, so obtaining said pipe. Its advantages are high automation level, simple process, low cost, and smooth surface and high strength of product.
Description
Technical field
The present invention relates to a kind of manufacture method of polytene corrugated tube, exactly relate to a kind of manufacture method of polyethylene double-wall corrugated pipe.
Background technology
The vinyon bellows is meant that tube wall is the tubing of concentric annular hollow rib, and ripple is parallel ring-like.Materials are economized, the rigidity height owing to have, and have been widely used in combustion gas conveying, feedwater, blowdown, agricultural irrigation, oil field, mine, chemical industry and post and telecommunications every field.The vinyon bellows has single wall and two kinds of tubing of double-walled, and the former occurs early being mainly used in agricultural Underdrainage pipe, because internal surface of pipe has convex-concave, fluid flow has to hinder makes its application be subjected to certain limitation.The double-walled plastic film capicitor grows up on the single-walled pipe basis, and the tube wall longitudinal section is made up of double-layer structure, and internal layer is smooth, and skin is a corrugated.Because in the middle of the tubing cross section of double-wall corrugated pipe is hollow, the bearing capacity height, save 50% above material than solid wall pipe under same bearer, this tubing is widely used in municipal administration, factory, agricultural drainpipe and communication cable sleeve pipe with its fabulous ratio of performance to price.
Existing polytene corrugated tube manufacture method has two kinds: first cyclic module general laws.This is a kind of current method, and subject matter is that the mould consumption is big, main frame head complexity, production cost height, the millions of units of a present Φ 600 double-wall corrugated pipe production line prices, and general medium and small manufacturing enterprise can't bear.It two is winding pipe methods.Have the people to twine drainpipe according to the double-walled spiral recently and make principle, designed double-wall corrugated pipe production method of a kind of wound form and equipment, advantage is that equipment is simple, inexpensive, and shortcoming is that the inner wall smooth degree is poor, and it is big that seepage appears in weld seam.
Summary of the invention
The objective of the invention is to: good, the bearing strength extra-high-speed of product inner wall smooth, weld anti-leakage that provide a kind of and supply streamline production, the production process flow process is short, automaticity is high, production efficiency is high, produces, the polyethylene double-wall corrugated pipe manufacture method that product cost is low.
The objective of the invention is to realize by the enforcement following technical proposals:
A kind of manufacture method of polyethylene double-wall corrugated pipe, the operation that is connected into body by polyethylene double-wall corrugated plate manufacturing process, double-wall corrugated coiled sheet boxing becomes the operation of pipeline section to be formed with cutting polyethylene double-wall corrugated pipe body in regular turn, it is characterized in that: in polyethylene double-wall corrugated plate manufacturing process, by extruder, special-purpose head and special-purpose extrusion die, produce the polyethylene double-wall corrugated sheet material of random waveform and any wave number through the vacuum cooled typing; Be connected in the operation of body in polyethylene double-wall corrugated coiled sheet boxing, this plate is placed on the reel of up-coiler, rotation with reel is reeled the plate face, the dual-side of this plate is overlapped to form body mutually simultaneously, along with the rotation of reel, overlap edge heated with pressurized treatments sheet material is welded into body after overlap joint is finished.
The invention has the advantages that: be fabricated onto from double-wall corrugated sheet material and make the bellows finished product, overall process is an automatic assembly line, and operation is short, so production efficiency height, product cost are low, particularly before the double-wall corrugated pipe moulding, corrugated plating is in winding process, the both sides of plate overlap mutually, heat the pressurization welding then, and this technology has increased the tube wall compression strength of Cheng Guanhou, also avoid lap-joint seepage to occur, thereby improved the quality of polyethylene double-wall corrugated pipe finished product widely.

The specific embodiment
A kind of manufacture method of polyethylene double-wall corrugated pipe is connected into plumber's preface by polyethylene double-wall corrugated sheet material manufacturing process, polyethylene double-wall corrugated coiled sheet boxing in regular turn and becomes the operation of pipeline section to form with the cutting polyethylene double-wall corrugated pipe; The double-wall corrugated plate of described PE manufacturing process includes the PE raw material extruder of packing into, is melt into flowable melt in extruder, from the head melt extrusion to special-purpose extrusion die, through mould is vacuumized, finalizes the design, is cooled to double-wall corrugated plate; By hauling machine the double-wall corrugated plate of PE is extracted out from mould then and drawn to up-coiler, carry out the double-wall corrugated coiled sheet boxing of PE and be connected into second operation of pipe, in this operation, the double-wall corrugated plate of PE is placed on the reel of up-coiler, this plate curls the plate face with the rotation of reel, the dual-side of this plate is overlapped to form body mutually in winding process, after overlap joint is finished, heating makes it to be melt into one to overlap edge by heater, by the overlap edge pressurization of rolling wheel to merging into an organic whole, the double-wall corrugated plate of PE this moment is welded into bellows body by volume then; Bellows body moves on on the cutting machine under thrust, and length on demand cuts into the task that pipeline section is finished the 3rd operation with body, at last finished product is put in storage.
Claims (1)
1, a kind of manufacture method of polyethylene double-wall corrugated pipe, the operation that is connected into body by polyethylene double-wall corrugated plate manufacturing process, double-wall corrugated coiled sheet boxing becomes the operation of pipeline section to be formed with cutting polyethylene double-wall corrugated pipe body in regular turn, it is characterized in that: in polyethylene double-wall corrugated plate manufacturing process, by extruder, special-purpose head and special-purpose extrusion die, produce the polyethylene double-wall corrugated sheet material of random waveform and any wave number through the vacuum cooled typing; Be connected in the operation of body in polyethylene double-wall corrugated coiled sheet boxing, this plate is placed on the reel of up-coiler, rotation with reel is curled the plate face, the dual-side of this plate is overlapped to form body mutually in winding process, along with the rotation of reel, overlap edge heated with pressurized treatments sheet material is welded into body after overlap joint is finished.
