Realize that above-mentioned purpose technical solution of the present invention is, a kind of method by continuously shaped manufacturing metal skeleton-plastic composition pipeline is provided, in plastics materials such as polyethylene or PVC adding extruder, the plastics materials that has become molten state through heating is pressed into the pipeline forming cavity, extrusion modling is to carry out cooling and shaping behind the pipe shape in forming cavity, pipeline behind the cooling and shaping is drawn by haulage gear, pipeline extrusion modling process is carried out continuously, according to the present invention, in this method, along being used as even configuration on the circumference of the Cylinder shape constructional element that welds supporting electrode, on longitudinal steel bar member tension and that do together to vertically move with pipeline, twine at a certain distance and strengthen spiral wire, along with winding, welding roll is rotated with the winding of spiral wire, when welding roll is crossed the longitudinal steel bar member, welding roll and supporting electrode electrically contact and give the welding current pulse, spiral wire is soldered on the longitudinal steel bar member, the netted tubular Framework Of Steel Reinforcement that obtains continuously by said process with the plastics materials melt that obtains continuously from extruder continuous send into the pipeline forming cavity.
In a preferred embodiment of the inventive method, its described longitudinal steel bar member is an even number, two become the welding roll of 180 ° of angle symmetric arrangement to rotate with spiral wire, when welding roll surpasses the longitudinal steel bar member, one of them welding roll is only given the welding current pulse to order for the longitudinal steel bar member of odd number and spiral wire, another welding roll is only given the welding current pulse to order for the longitudinal steel bar member of even number and spiral wire, thereby obtains netted tubular Framework Of Steel Reinforcement continuously.
In another preferred embodiment of the inventive method, in the continuously shaped netted tubular Framework Of Steel Reinforcement process of welding, that its tubular supporting electrode and welding roll are done is relative, longitudinally, continuous at the uniform velocity to-and-fro motion.
The present invention also provides a kind of device of making metal skeleton-plastic composition pipeline, comprising: plastic extruder, cooling mechanism and tractor, according to the present invention, be equipped with the material output pipeline of band longitudinal steel bar guiding groove at the outlet of extruder place; By stationary core rod and the fixing forming cavity formed of lining, forming cavity is equipped with the cylinder of the coiled die cavity rotation of band rotary actuator outward, rolls the little reel of spiral wire is housed in the adjustment; Exert pressure and by the welding roll and the conductive hoop of cylinder driven rotary by spring; Be sleeved on tubular supporting electrode that the material output pipeline has the longitudinal steel bar guiding groove outward be positioned at the corresponding position of welding roll on.
A preferred embodiment of apparatus of the present invention, its tubular supporting electrode or welding roll be provided with make both do relative longitudinally with continuous at the uniform velocity reciprocating power plant.
Another preferred embodiment of apparatus of the present invention, the skin of its forming cavity is provided with ring-type heating unit and device for monitoring temperature.
According to method and apparatus of the present invention, can produce plastic pipe with higher mechanical strength, the working pressure that is allowed under the room temperature can reach 9MP a, its withstand voltage properties improves nearly 10 times than known plastic pipe.
Below by the more detailed explanation the present invention of drawings and Examples of the present invention, in the accompanying drawing:
Fig. 1 is according to device close-up view of the present invention;
Fig. 2 is the local longitudinal sectional drawing of apparatus of the present invention;
Fig. 3 is the longitudinal sectional drawing of forming cavity
Fig. 4 is the B-B sectional drawing of Fig. 2.
The method of continuously shaped metal skeleton-plastic composition pipeline is, plastics materials is added extruder 4, the plastic melt that becomes molten state through heating is pressed into pipeline forming cavity 9, extrusion modling is to carry out cooling and shaping behind the pipe shape in pipeline forming cavity 9, pipeline by haulage gear 5 traction moulding is carried out pipeline extrusion modling process continuously.
According to the inventive method, in pipeline extrusion modling process, evenly disposing on the circumference of the Cylinder shape constructional element that weld supporting electrode 10 along being used as, on the longitudinal steel bar member 2 tension and that do together to vertically move with pipeline, twine reinforcement spiral wire 3 according to certain spacing, along with winding, welding roll 6 and 6a are rotated with the winding of spiral wire, when welding roll 6 and 6a cross longitudinal steel bar member 2, welding roll 6 or 6a and supporting electrode 10 electrically contact and give the welding current pulse, spiral wire 3 is soldered on the longitudinal steel bar member 2, thereby continuous obtain netted tubular Framework Of Steel Reinforcement, with the above-mentioned netted tubular Framework Of Steel Reinforcement that obtains continuously with the plastic melt that obtains continuously from extruder 4 continuous send into pipeline forming cavity 9.The quantity of described longitudinal steel bar member is designed to even number, with what two welding rolls 6 and 6a replaced longitudinal steel bar member 2 and spiral wire 3 are imposed the welding current pulse, for example 6 of welding rolls impose the welding current pulse to order for the longitudinal steel bar member of odd number and spiral wire, and welding roll 6a is only to imposing the welding current pulse for the longitudinal steel bar member of even number and spiral wire in proper order.According to this example, becoming 180 ° of symmetrically arranged welding rolls in angle under the spring action of exerting pressure the active force of material conveying pipe to be made a concerted effort is zero, overcome the lateral pressure of single welding roll center roller, make it to reach equilibrium of forces, guarantee the inner tube wall quality, another embodiment according to the inventive method, twine in the welding process at spiral wire 3, the relative supporting electrode 10 with 6a of welding roll 6 is done longitudinally, continuous at the uniform velocity to-and-fro motion, avoided the fixed point of supporting electrode in welding process to ablate the working life of having improved supporting electrode.
