Abstract
The utility model discloses a plastic solid-wall bellows tubes molding cooling device, which comprises an external sizing sleeve for sizing and cooling the external surfaces of hollow billets, whereinan inner cooling molding device for cooling and molding the internal surfaces of hollow billets is sheathed in the external sizing sleeve, the external sizing sleeve guarantees the external diameterand the smoothness of the external surface of bellows tubes, the inner cooling molding device guarantees the smoothness of the inner wall of the bellows tubes and the evenness of the tube wall thickness, the double cooling of the internal and the external surfaces of bellows tubes is achieved, thereby enhancing the cooling efficiency and effectively solving the problem that large-diameter plasticsolid-wall tubes are melted to droop. The length of a cooling section is only the half of that of the traditional extrusion production line, meanwhile as the length of the cooling section is reduced,the cooling water circulation consumption is doubly lowered.
Description
Technical field
The utility model relates to a kind of device of plastics solid wall pipe material forming.
Background technology
At present the production of plastics solid wall pipe material is extruded pipe by extrusion die, cool off after preliminary typing, thereby it is solid-state to make plastic pipe be by shapeable that the molten state of specific dimensions and shape changes into the manufacturing of realization plastic pipe.Plastic pipe moulding cooling is first behind the outer surface cooling and shaping of tubing, more gradually to the inside of plastic pipe cooling and shaping, and finally pipe material inner wall is cooled off, until the complete cooling and shaping of whole tube wall of tubing.When adopting this kind mode to produce real wall plastic pipe, the cooling of plastics is that ecto-entad carries out gradually, because the poor thermal conductivity of plastics, the plastic cool at tubing core and inwall place is slower, tubing typing is longer required cool time, and is often insufficient to the cooling and shaping of plastic pipe.When producing large diameter plastic pipe, tend to cause occur the molten phenomenon of hanging down.Promptly because the plastics of molten state are still arranged before plastic pipe is finalized the design fully, under the gravity effect, continue to flow to the horizontal minimum point place of tubing, thereby form the plastic tube that wall thickness does not wait, make the tube wall thickness inequality, have a strong impact on the overall performance of tubing, cooling and shaping efficient is low simultaneously, has also restricted the lifting of plastic pipe production efficiency.
The utility model content
Technical problem to be solved in the utility model provides a kind of plastics solid wall pipe material forming cooling device that prevents to occur in the plastic pipe manufacture process the molten phenomenon of hanging down.
For solving the problems of the technologies described above, the technical solution of the utility model is: plastics solid wall pipe material forming cooling device, comprise outer calibration sleeve, be set with the interior cooling and shaping device that internal surface of bloom is cooled off and finalizes the design in the described outer calibration sleeve outer surface of tube blank sizing and cooling.
As optimized technical scheme, described interior cooling and shaping device is the cooling and shaping cover that contacts with internal surface of pipe, is provided with coolant guiding channel in the described cooling and shaping cover.
As to improvement of the technical scheme, described coolant guiding channel is the spiral helicine coolant guiding channel that is provided with along described coolant jacket jacket wall.
Owing to adopted technique scheme, plastics solid wall pipe material forming cooling device comprises the outer calibration sleeve to outer surface of tube blank sizing and cooling, is set with the interior cooling and shaping device that internal surface of bloom is cooled off and finalizes the design in the described outer calibration sleeve; Outer calibration sleeve has guaranteed the smooth of the outer dia of tubing and outer surface, interior cooling and shaping device guaranteed pipe material inner wall smooth and thickness of pipe wall evenly, realized the dual-cooled on the inside and outside surface of tubing, thereby improved cooling effectiveness; And effectively solving the vertical phenomenon of melting of major diameter plastics solid wall pipe, the length of cooling section only is half of traditional extruding production line; Simultaneously, because the length of cooling section reduces, the cooling water circulating consumption also reduces at double.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, plastics solid wall pipe material forming cooling device comprises the outer surface sizing of pipe 2 and the outer calibration sleeve 1 of cooling, is set with the interior cooling and shaping device 3 that the inner surface to pipe 2 cools off and finalizes the design in the described outer calibration sleeve 1.
Cooling and shaping device 3 is the coolant jacket that adapts with pipe internal diameter in described, is provided with coolant guiding channel 31 in the described coolant jacket.In the present embodiment, described coolant guiding channel 31 is the spiral helicine coolant guiding channel that is provided with along described coolant jacket jacket wall.
The interior cooling and shaping device 3 of present embodiment is installed in the end of extrusion die core 4.Pipe 2 outer walls were close to the inwall sizing typing of outer calibration sleeve 1 when tubing was produced, and directly contacted with cooling medium simultaneously and cooled off; And the pipe inwall contacts with the outer surface of interior cooling and shaping device 3, after interior cooling and shaping device 3 heat absorptions, heat is delivered to the cooling medium that circulates rapidly, and the cooling medium that successively circulates is taken the heat of tubing production out of.Thereby make the cooling length of tubing manufacturing equipment shorten half, production line operation power consumption reduces more than 20%.
Claims (3)
