Description
Technical field
The utility model belongs to plastic pipe production equipment technical field, is specifically related to the pre-cooled device of a kind of polyolefin pipe pipe.
Background technology
Plastic pipe is as the important component part of chemical building material, and with its superior performance, health, environmental protection, low consumption etc. are accepted extensively by users, mainly contain the UPVC drainpipe, the UPVC feed pipe, and PAP, these are several for polyethylene (PE) water-feeding pipes.Pipe production line is made up of control system, extruder, head, typing cooling system, hauling machine, planet cutter sweep and tilting trestle.Every pipe production line has two extruders, and its main extruder adopts powerful lining and the efficient screw rod carried, and another less extruder is used for extruding markings.When plastic tube product line breaks down, can directly cause plastic pipe rough surface to occur, Dithering Loops appears in inside, and phenomenons such as no vacuum so will in time get rid of the plastic tube product line fault, just can be improved the quality of products.
PE pipe production line structure uniqueness, the automaticity height, easy to operate, continuously produce reliable and stable.The pipeline of this plastic tube product line production has appropriate rigidity, intensity, has good flexibility, creep resistant, environmental stress crack resistance and good thermal welding performance again, has become the first-selected product of gas conveyance conduit and outdoor water supply pipe.The PE pipe production line is made up of control system, extruder, head, typing cooling system, hauling machine, planet cutter sweep and tilting trestle.Every pipe production line has two extruders, its main extruder adopts powerful lining and the efficient screw rod carried, another less extruder is used for extruding markings, also have mould and subsidiary engine: head adopts newly designed basket head or spiral shunting to squeeze the pipe composite machine head, have easy to adjust, the uniform characteristics of discharging, calibration sleeve adopt unique grooving processes and water ring cooling, guarantee the formed precision of tubing.
The PE pipe production line adopts the efficient screw rod of PE, fluting machine barrel, and has powerful water jacket cooling, has improved conveying capacity greatly, guarantees efficiently to extrude; High moment of torsion vertical structure reduction box; Direct-drive motor.The basket compound die head that is suitable for polyolefin processing had both guaranteed the stability efficiently extruded can realize minimum stress and maximum tube material amount that low melt temperature is brought again.Adopt efficient two-chamber vacuum sizing technology and spraying cooling water groove, improve the yield rate of tubing, satisfy the needs of high-speed production.Adopt the multi-track hauling machine, the tractive force uniform and stable, each crawler belt is by AC servo machinery driving independently, and realized that by the actuation techniques of digital controller control speed is regulated accurately, with reach height synchronously.The cutting machine that adopt high speed, accurately designs, cutting section is smooth, and is furnished with powerful bits-suction device, maintenance work is down to minimum.
At present, polyolefin pipe the tube surfaces pitting can often occur in process, thereby influences pipe workpiece quality.It is too high that the principal element that produces this phenomenon is exactly the outer cooling water hole ejection water droplet speed of calibration sleeve, and the big or little hole plug of impulse force does not form mist, forms little water droplet, acts on the high temperature pipe of outlet mould, causes pitting, age spot.After tubing entered the vacuum sizing case, cooling water carried out from outside to inside cooling to tubing, vacuumizes the surface recovery that can't make tubing.Because the apopore on the calibration sleeve water ring, the aperture is less, manually is difficult for regulating and regulates after the hydraulic pressure tubing going out behind the sizing case just observable effects.So just make troubles to production control, produce more defective work.
Summary of the invention
The purpose of this utility model provides the pre-cooled device of a kind of polyolefin pipe pipe, makes airtight circular cylinder by brass, and two ends are provided with intake-outlet up and down, and the adjusting ball valve is housed, can control water yield size, reduce the product fraction defective, improve production efficiency.
The utility model is achieved through the following technical solutions:
The pre-cooled device of a kind of polyolefin pipe pipe, it is characterized in that: described pre-cooled device 3 is airtight circular cylinder, inner chamber is the material stream passed passage, described material stream passed passage is connected with extrusion equipment entrance point material inlet, pre-cooled device 3 is connected with extrusion equipment by regulating screw mandrel 4, pre-cooled device 3 lower ends are provided with water inlet, the upper end is provided with delivery port, and the adjusting ball valve is housed, between pre-cooled device 3 and extrusion equipment, also be provided with water ring 5, calibration sleeve 6 interference fit on described water ring 5 and the extrusion equipment.
Described pre-cooled device 3 annular inner surfaces are through polishing or electroplating processes.
Described pre-cooled device 3 adopts metal material to make.
Described pre-cooled device 3 materials are iron or stainless steel or copper.
The beneficial effects of the utility model:
The pre-cooled device of described a kind of polyolefin pipe pipe, overall construction design is simple, make airtight circular cylinder by brass, two ends are provided with intake-outlet up and down, and the adjusting ball valve is housed, and can control water yield size, in the polyolefin pipe production process, solve the bad problem of tube surfaces, reduced the product fraction defective, improved production efficiency.
Description of drawings
Fig. 1 is the utility model partial sectional view.
Fig. 2 is M enlarged drawing among Fig. 1.
Among the figure, extrusion die 1, pipe 2, pre-cooled device 3, adjusting screw mandrel 4, water ring 5, calibration sleeve 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
The pre-cooled device of a kind of polyolefin pipe pipe, as accompanying drawing 1, shown in 2, described pre-cooled device 3 is airtight circular cylinder, described pre-cooled device 3 adopts iron or stainless steel or copper metal material to make, pre-cooled device 3 annular inner surfaces are through polishing, or electroplating processes, inner chamber is the material stream passed passage, described material stream passed passage is connected with vacuum sizing case entrance point material inlet, pre-cooled device 3 is connected with the vacuum sizing case by regulating screw mandrel 4, pre-cooled device 3 lower ends are provided with water inlet, the upper end is provided with delivery port, and the adjusting ball valve is housed, between pre-cooled device 3 and extrusion equipment, also be provided with water ring 5, calibration sleeve 6 interference fit on described water ring 5 and the vacuum sizing case.
Before after high temperature polyolefin pipe 2 is extruded by extrusion die 1, entering calibration sleeve 6, carry out pre-cooled in the mode of heat transmission in advance, make the tube surfaces temperature reduce the 20-30 degree, thereby form the very thin harder shell of one deck in tube surfaces, after entering calibration sleeve 6, form pitting with regard to not being subjected to the bigger water droplet influence of speed.Owing to just the tube surfaces temperature is reduced the sizing moulding that can't have influence on tubing slightly.Pre-cooled device is provided with intake-outlet in two ends about in the of 3, and the adjusting ball valve is housed, and in the full water, regulates to guarantee cooling effect by the water yield in guaranteeing confined space, and unlikely cooling is excessive again.Be equipped with in the device both sides and regulate screw mandrel 4 and be fixed on the vacuum sizing case, can adjust distance between cooling device and a mouthful mould, the sizing case by regulating screw mandrel 4, assurance tubing can not influence the tube forming process in the friction of pre-cooled device 3.Thereby reduced the product fraction defective, improved production efficiency.
