Abstract
The utility model discloses a handpiece for manufacturing a plastic pipe fitting. The handpiece comprises a core die and a die body, wherein a material inlet channel is arranged on the die body and is communicated with an extrusion channel formed between the core die and the die body; and a melt enters from the material inlet channel and is extruded out of the extrusion channel, so that a pipe blank is formed. The handpiece is characterized by also comprising an air blowing pipe and an air extracting pipe which are positioned in the core die; one end of the air blowing pipe is led into the pipe blank, and the other end of the air blowing pipe is connected with an air fan arranged outside the core die; and one end of the air extracting pipe is led into the pipe blank, and the other end of the air extracting pipe is connected with an exhaust fan arranged outside the core die. The handpiece has the advantages that the inner surface of the pipe blank is quickly cooled, the production speed is increased, the using amount of cooling water is reduced, and the energy consumption is reduced; and moreover, melt dropping of the pipe fitting is improved, the smoothness of the inner surface of the pipe fitting is improved, and the quality of the pipe fitting is improved.
Description
Technical field
The utility model relates to a kind of head, relates in particular to a kind of for the head of making plastic pipe.
Background technology
In the plastic pipe process of routine, the cooling of tubing is just cooled off at the outer surface water spray of tubing, tubing is immersed in the water cools off, and internal surface of pipe can only lean on the nature cooling.Because the heat-transfer effect of plastics is poor, so the internal surface of pipe cooling slowly, thereby make and need to increase more cooling device, causes pipe production line long, and it is excessive to take up an area of the space, and energy consumption is bigger; Simultaneously, because the inner surface cooling is untimely, cause tubing molten vertical easily, wall thickness deviation is big up and down, and the tubing internal stress is big, and the easy oxidation of internal surface of pipe, makes internal surface of pipe of poor quality.In view of the foregoing, demand urgently existing process equipment is carried out structural improvement.
The utility model content
The utility model purpose is to overcome the problems that tubing is depended merely on water quench, has proposed a kind of novel mechanism that is used for making plastic tube.
The technical solution of the utility model is achieved in that a kind of for the head of making plastic pipe, comprise: core and die body, wherein, this die body is provided with a feeding-passage, what form between this feeding-passage and core and the die body one extrudes passage and is connected, melt enters from this feeding-passage, extrude through extruding passage, the moulding pipe, it is characterized in that: also comprise the blower and the exhaust column that are positioned at described core, one end of this blower leads in the described pipe, and the other end and is arranged on the outer hair-dryer of described core and is connected; One end of this exhaust column leads in the described pipe, and the other end and is arranged on the outer air exhauster of described core and is connected.
As a kind of preferred version for the head of making plastic pipe, described hair-dryer is connected with a drying.
As a kind of preferred version for the head of making plastic pipe, described feeding-passage is arranged on the side of described die body, in order that reserve the inner space of core to greatest extent, to reach the diameter that increases blower and exhaust column.
As a kind of preferred version for the head of making plastic pipe, comprise that also one is positioned at the deep bead of described pipe, this deep bead is arranged on the place ahead of described blower and exhaust column and is connected versatilely on the described core by screw mandrel, can change the length of screw mandrel as required, thereby regulate deep bead apart from the distance of blower and exhaust column.
As a kind of preferred version for the head of making plastic pipe, the outer surface of described blower is provided with thermal insulation layer, has avoided cold air to be heated.
Compared with prior art, the utlity model has following advantage:
One, cuts down the consumption of energy raising speed.Because internal surface of pipe has obtained quick cooling, has reduced the consumption of cooling water, has saved energy consumption, has also improved speed of production.
Two, improved pipe workpiece quality.The quick cooling of inner surface has improved the molten of tubing and has hung down, and has reduced the wall thickness deviation of tubing; Also reduce the oxidation of internal surface of pipe, improved the fineness of internal surface of pipe.Because cool off simultaneously on the inside and outside surface of tubing, also reduced the internal stress of tubing simultaneously.
Three, reduce cost.The quantity of cooling device has been saved in the quick cooling of inner surface, has shortened the length of production line, has saved equipment cost.
Description of drawings
Fig. 1 has the schematic diagram of inner cooling system head for the utility model.
Fig. 2 is blowing of the present utility model and exhausting system schematic diagram.
Among the figure: 1 is drying, and 2 is hair-dryer, and 3 is air exhauster, and 4 is feeding-passage, and 5 is core, and 6 is die body, and 7 for extruding passage, and 8 is blower, and 9 is exhaust column, and 10 is deep bead, and 11 is pipe.
The specific embodiment
As depicted in figs. 1 and 2 be a kind of head that has inner cooling system, it comprises drying 1, hair-dryer 2, air exhauster 3, feeding-passage 4, core 5, die body 6 is extruded passage 7, blower 8, exhaust column 9, deep bead 10, pipe 11.
Exhaust column 9 and blower 8 are installed in the core of core 5 side by side; One end of exhaust column 9 links to each other with air exhauster 3, and an end of blower 8 links to each other with an end of hair-dryer 2, and the other end of hair-dryer 2 is connected with drying 1; Die body is connected with feeding-passage 4 on 6 sides, forms between core 5 and the die body 6 and extrudes passage 4.Become pipe 11 from extruding the melt that passage 7 extrudes, head be connected with deep bead 10 foremost.
During use, the melt of extruding from extruder enters the core 5 from feeding-passage 4, and is diverted to uniformly by core 5 and extrudes in the passage 7, extrudes from the front end of extruding passage 7 then and forms pipe 11.Drying 1 is with the cold air drying, hair-dryer 2 cold air that drying is crossed is blown in the blower 8 and blows to deep bead 10 from the other end of blower 8 then, cold air is blowed the inner surface of pipe 11 through stopping of deep bead, and air exhauster 3 is extracted cold air out more fast by exhaust column 9, like this, cold air has obtained circulation fast, has realized the quick cooling of internal surface of pipe.
Behind said structure, at first by drying with the cold air drying, avoided airborne moisture run into heat pipe and become the globule, hair-dryer cold air that drying is crossed is blown in the blower and blows to deep bead from the other end of blower then, and cold air is under the effect of deep bead and blow to the inner surface of tubing; And air exhauster is extracted cold air out more fast by exhaust column, and like this, cold air has obtained circulation fast, has realized the quick cooling of internal surface of pipe.
Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
