Description
Technical field
The utility model is related to the systems of the manufacturing method of helical bellows, especially steel band reinforced polyethylene spiral ripple pipe
Make method.
Background technology
Steel band reinforced polyethylene spiral ripple pipe has many advantages, such as inner wall smooth, critical external compressive resistance ability is strong, corrosion-resistant, is
Ideal buried drainage pipe.Traditional steel band reinforced polyethylene spiral ripple pipe is by inner layer polyethylene, helical steel band and outer
Strata ethylene is formed, and molding is directly completed on extruding machine, in construction, by the end of steel band reinforced polyethylene spiral ripple pipe
Then mouth docking, winds hot melt strip, secondary be heated of hot melt strip makes helical bellows link together, and use is this in interface
Mode connects helical bellows, needs the repair welding at the inner wall of interface, operation and its inconvenience, and the efficiency constructed is low.
Invention content
The purpose of this utility model is to provide for a kind of connector and is not easy to deform, dimensionally stable, enhances polyethylene spiral shell
Bellows is revolved, and improves degree of being completely embedded between the bell of pipe and socket.
The purpose of this utility model is realized by following technical scheme：
A kind of enhancing polyethylene helical bellows, steel band reinforced polyethylene spiral ripple pipe are included by arranging successively from inside to outside
The helical corrugation tube body 1 being made of inner layer polyethylene, helical steel band and outer layer polyethylene of row, helical corrugation tube body 1 include poly-
Ethylene inner tube, shaped-steel strip and polyethylene outer tube, the equidistant outer surface for being wound in polyethylene inner tube of shaped-steel strip, shaped-steel strip
Outer cladding polyethylene outer tube, 1 both ends of helical corrugation tube body are socket 3 and bellmouth 2, and socket is equipped with wedge-type seal circle 6, and described close
The outer rim of seal higher than the socket outer rim and be provided with a circle Electric thermal smelting belt 4, hot melt guipure has both ends, on both ends
Be connected with electrode 5, convenient for extraneous electrical communication；The bellmouth from opening toward the inner wall in tube body direction on be provided with a circle
Wedge-shaped impression；The section triangle at a right angle of the wedge-shaped impression.A kind of enhancing polyethylene helical bellows of the utility model
Tube body and connector are separately molded, and are then connected connector with steel band reinforced polyethylene spiral ripple pipe ontology, relative to existing skill
The one-pass molding of art is easy, and manufacture is at low cost.When manufacturing connector, using being cut after extrusion, connector is not easy to deform, size
Stablize.It is by the step that hot melt guipure is fused in connector on the outer surface of socket：Hot melt guipure is wrapped in socket first
On outer wall, then, receptacle wall is heated, while apply the outer surface that pressure makes hot melt guipure be fused to socket to hot melt guipure
On.Since hot melt guipure is banded structure, surface area is big, therefore, is not easy to fall from socket when being wound on socket；It is right
It heats guipure and applies pressure, hot melt guipure is made to be embedded into socket, improve the reliability of hot melt guipure welding, and improve pipe
Degree of being completely embedded between bellmouth and socket.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The present invention is further described in detail with reference to the accompanying drawings and detailed description.
As shown in the figure, a kind of enhancing polyethylene helical bellows of the utility model, steel band reinforced polyethylene spiral ripple
Pipe includes the helical corrugation tube body being made of inner layer polyethylene, helical steel band and outer layer polyethylene by being arranged in order from inside to outside
1, helical corrugation tube body 1 includes polyethylene inner tube, shaped-steel strip and polyethylene outer tube, and shaped-steel strip is equidistant to be wound in poly- second
The outer surface of alkene inner tube, shaped-steel strip outer cladding polyethylene outer tube, 1 both ends of helical corrugation tube body be socket 3 and bellmouth 2, socket
Equipped with wedge-type seal circle 6, and the outer rim of the sealing ring is higher than the outer rim of the socket and is provided with a circle Electric thermal smelting belt 4, heat
Molten guipure has both ends, and electrode 5 is connected on both ends, convenient for extraneous electrical communication；The bellmouth from opening toward
A circle wedge-shaped impression is provided on the inner wall in tube body direction；The section triangle at a right angle of the wedge-shaped impression.Manufacture connector
When, using being cut after extrusion, connector is not easy to deform, dimensionally stable.Connector is installed on the first fixture, the poly- second of steel strip reinforced
Alkene helical corrugation tube body is installed on the second fixture, is firmly installed, connector and steel band reinforced polyethylene spiral ripple pipe ontology
It, can when connector is docked with steel band reinforced polyethylene spiral ripple pipe ontology easily to just and to deviation will not be generated after just
Apply pressure, connector is made to be connected firmly, reliably with steel band reinforced polyethylene spiral ripple pipe ontology, therefore, the steel manufactured
With the high-quality of enhancing polyethylene helical bellows.The wall thickness of connector is required when manufacturing steel band reinforced polyethylene spiral ripple pipe
More than the thickness of steel band reinforced polyethylene spiral ripple pipe, therefore, when melting interface, first heated coupling 3-8min so that connect
Head is identical with the molten condition of steel band reinforced polyethylene spiral ripple pipe, improves the fastness of docking.
