Description
The present invention relates to continuously extruding and molding manufactured metal frame---the method and the device of plastic composition pipeline.
Known method by continuous extrusion manufacturing plastic pipe is that plastics materials is added in the extruder, having become the plastics materials of molten state to be pressed into the hard tube head through heating, carry out cooling and shaping after in head, being shaped to pipe shape, pipeline behind the cooling and shaping is pulled out by tractor, and the pipeline extrusion modling is carried out continuously.
Known device by continuous extrusion manufacturing plastic pipe comprises: plastic extruder, hard tube head, cooling mechanism and haulage gear.
As everyone knows, can only produce plastic pipe with above-mentioned method and apparatus, though and plastic pipe to have corrosion resistance strong, the advantage that the pipeline internal resistance is lower, but because the mechanical strength of plastics itself is lower, the plastic pipe of moulding according to said method can not be used in higher occasion of pressure and environment.
In addition, once the someone proposed to increase the imagination of wire netting in plastic pipe, but did not still have the enforcement that any concrete manufacturing method and apparatus guarantees this imagination.
The purpose of this invention is to provide a kind of so that the method and apparatus of the plastic pipe that strengthens wire netting to be arranged in the continuously extruding and molding manufactured tube wall.
Manufacturing metal frame of the present invention---the method for plastic composition pipeline comprises: (1) adds in the extruder plastics materials through heating and becomes molten state; (2) on the longitudinal steel bar guiding groove of the tubular supporting electrode that is arranged at the outlet of extruder place, evenly dispose the longitudinal steel bar member of straining, twine the reinforcement spiral wire at a certain distance along reinforcement component, rotate with the winding of spiral wire with the welding roll of the corresponding setting of tubular supporting electrode, spiral wire is welded on the longitudinal steel bar member thereby when each longitudinal steel bar member is crossed in its rotation, electrically contact and produce the weld pulse electric current, forms netted tubular Framework Of Steel Reinforcement continuously with supporting electrode; (3) netted tubular Framework Of Steel Reinforcement is sent into the multiple tube forming cavity continuously with the plastics materials of the molten state that obtains from extruder, extrusion modling is carried out cooling and shaping after being with the metal frame pipe shape in forming cavity, multiple tube behind the cooling and shaping is pulled out by haulage gear, and multiple tube extrusion modling process is carried out continuously.
Manufacturing metal frame of the present invention---the device of plastic composition pipeline comprises plastic extruder, cooling mechanism and tractor thing, it is characterized in that the outlet of extruder place is provided with molten plastic material output pipeline, its outside suit has the tubular supporting electrode of longitudinal steel bar guiding groove, the multiple tube forming cavity that is connected with the material output pipeline by stationary core rod and fixedly lining form, forming cavity is equipped with the cylinder of the coiled die cavity rotation of band rotary actuator outward, and the little reel of spiral wire is housed on the cylinder.With the welding roll of the corresponding configuration of tubular supporting electrode and conductive hoop is exerted pressure by spring and by the cylinder driven rotary.
Can produce multiple tube continuously according to method and apparatus of the present invention with higher mechanical strength, the working pressure that is allowed under its room temperature can reach 9Mpa, its withstand voltage properties is than high nearly 10 times of known plastic pipe, kept the corrosion resistance that plastic pipe had strong simultaneously, the advantage that the pipeline internal resistance is lower.
With embodiment the present invention is done more detailed description below in conjunction with accompanying drawing.
Fig. 1 is a schematic representation of the present invention;
Fig. 2 is a longitudinal sectional drawing of the present invention;
Fig. 3 is the sectional drawing of forming cavity of the present invention;
Fig. 4 is a B-B sectional drawing among Fig. 2 of the present invention.
As shown in Figure 2, the present invention includes a material output pipeline 16 and a multiple tube forming cavity 9, both are connected, and wherein the outer cover of output pipeline 16 is equipped with tubular supporting electrode 10 (see figure 3)s, and supporting electrode is provided with the longitudinal steel bar guiding groove; Multiple tube forming cavity 9 by stationary core rod 11 and fixedly lining 17 form (see figure 3), the cylinder 8 that rotates around it is equipped with in the outside of forming cavity 9, cylinder 8 is by the rotary actuator driven rotary of installing on it, as shown in Figure 4, spiral wire rap wheel 14 is housed on the cylinder 8, a pair of welding roll 6,6a and conductive hoop 7 are exerted pressure by cylinder 8 driven rotary and by spring 13, aforesaid tubular supporting electrode 10 and welding roll 6,6a corresponding setting mutually.
When making multiple tube according to method of the present invention, earlier longitudinal steel bar member 2 is placed tightened position in the longitudinal steel bar guiding groove, afterwards spiral wire 3 is wound on the longitudinal steel bar member 2 according to a determining deviation, welding roll 6 and 6a rotate with the winding of spiral wire 3 simultaneously, when welding roll 6 and 6a cross longitudinal steel bar member 2, itself and supporting electrode 10 electrically contact and produce the weld pulse electric current, and spiral wire 3 is welded on the longitudinal steel bar member 2, obtain netted tubular Framework Of Steel Reinforcement therefrom continuously.
As shown in Figure 1, the present invention includes extruder 4, after plastics materials is added into extruder 4 and passes through heating and becomes molten state, promptly be pressed into multiple tube forming cavity 9 by the output pipeline 16 that is communicated with extruder 4 outlets, netted tubular Framework Of Steel Reinforcement also is admitted to forming cavity 9 simultaneously, after molten plastic is squeezed into the pipe shape of band Framework Of Steel Reinforcement in forming cavity 9, behind cooling mechanism 15 cooling and shapings, become pipeline, and be pulled mechanism and pull out forming cavity 9, the manufacture process of multiple tube is carried out continuously.
As preferred embodiment of the present invention, configurable even number longitudinal steel bar member 2, and welding roll 6 becomes 180 ° of angle symmetric arrangement with 6a, one of them welding roll is only given into weld pulse electric current for the reinforcement component of odd number with spiral wire to order, another welding roll is then only given the weld pulse electric current to order for the longitudinal steel bar member of even number and spiral wire, according to present embodiment, 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, thereby overcome the lateral pressure that adopts single welding roll center roller, and reach equilibrium of forces, guarantee the tube wall quality.
As another preferred embodiment of the present invention welding process can make welding roll 6 and 6a with respect to supporting electrode 10 do longitudinally, relative, continuous at the uniform velocity to-and-fro motion, thereby avoided the fixed point of supporting electrode in welding process to ablate the working life of having improved supporting electrode.
