Description
Technical field
The present invention relates to sebific duct and manufacture field, particularly a kind of extrusion device.
Background technology
The shortcoming of shape of the mouth as one speaks sub-assembly in the past needs constantly to regulate the shape of the mouth as one speaks that sebific duct just can be made to have qualified section size and uniform wall thickness concentricity.There is provided a kind of new right-angle handpiece extrusion system at this, the casing of its cross head extruder has the sub-assembly can installing a fixed center or the non-adjustable shape of the mouth as one speaks, from the whole process starting to full speed running, can balance the flowing of flowing sizing material to the shape of the mouth as one speaks.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of extrusion device.
Technical scheme of the present invention is: a kind of extrusion device, it is characterized in that comprising extrusion system and sub-assembly; Described extrusion system comprises casing, conical inner wall surface, temperature-controlled area section, screw thread, pipeline; Described sub-assembly comprises thorax, current divider, guide groove, guide groove in frustum outer surface, bump surface, tubulose.The casing of described extrusion system has a conical inner wall surface, described casing has thread surface in its front end, described casing is provided with through inner pipeline, with two temperature-controlled area sections in described casing, described sub-assembly nut (not shown) is fixed in casing, and nut is screwed on casing by screw thread; Described sub-assembly of extruding is positioned in casing, the frustum outer surface of sub-assembly is meshed with the conical inner wall surface of casing, described sub-assembly has thorax in the consistent tubulose of an internal diameter to run through whole sub-assembly, current divider is established in described sub-assembly, be provided with guide groove between described bump surface, thorax in tubulose can be reached by guide groove.
The present invention is a kind of without the need to regulating extrusion system from " setting " pattern continuously to " normally running " period, can extrude the sebific duct of predetermined section size and uniform wall thickness concentricity.

Detailed description of the invention
Known by figure, a kind of extrusion device of the present invention, a kind of extrusion device, is characterized in that comprising extrusion system 10 and sub-assembly 20; Described extrusion system 10 comprises casing 11, conical inner wall surface 12, temperature-controlled area section 13, screw thread 14, pipeline 15; Described sub-assembly 20 comprises thorax 23, current divider 24, guide groove 25, guide groove 26 in frustum outer surface 21, bump surface 22, tubulose.The casing 11 of described extrusion system 10 has a conical inner wall surface 12, described casing 11 has screw thread 14 surface in its front end, described casing 11 is provided with through inner pipeline 15, with two temperature-controlled area sections 13 in described casing 11, described sub-assembly 20 nut (not shown) is fixed in casing 11, and nut is screwed on casing 11 by screw thread 14; Described sub-assembly 20 of extruding is positioned at casing 11 li, the frustum outer surface 21 of sub-assembly 20 is meshed with the conical inner wall surface 12 of casing 11, described sub-assembly 20 has thorax 23 in the consistent tubulose of an internal diameter to run through whole sub-assembly 20, current divider 24 is established in described sub-assembly 20, be provided with guide groove 25 between described bump surface 22, thorax 23 in tubulose can be reached by guide groove 25.
Working method: in the extrusion system profile shown in Fig. 1, the casing 11 of extrusion system 10 has a conical inner wall surface 12, and it is less than the internal diameter in casing 11 rear end at the internal diameter of casing 11 front end.Casing 11 has screw thread 14 surface in its front end, to be screwed on casing 11 by shape of the mouth as one speaks head (not shown).A sub-assembly 20 nut (not shown) is fixed in casing 11, and this nut uses screw thread 14 to be screwed on casing 11, and the frustum outer surface 21 of sub-assembly 20 is meshed with the conical inner wall surface 12 of casing 11.Extrude sub-assembly 20 and have thorax 23 in a tubulose, in tubulose, thorax 23 internal diameter is consistent, runs through whole sub-assembly 20, in order to transportion wire, core pattern or pipe fitting (not shown).
Sizing material (as unvulcanized sizing material) at elevated pressures and temperatures, is transported to the inside of casing 11 by pipeline 15.Pressure and temperature used is sizing material by extrusion system pressure and temperature used.Sizing material is distributed by the guide groove 25 between bump surface 22 by the current divider 24 in fixed center shape of the mouth as one speaks sub-assembly 20, equably sizing material is separated into two substantially equal parts, namely equal flow.Sizing material continues through guide groove 26 and distributes forward, and the sizing material of these two moieties and flow is finally separated into the sizing material of four moieties equably.Finally, sizing material is directed to thorax 23 in tubulose.Here, sizing material or be evenly distributed over and be coated on a cylindrical object (as sebific duct, electric wire or core pattern), has the sizing material tubular structure of the section size of specifying and uniform wall thickness concentricity to provide one; Or for providing a unsupported flexible pipe.In casing 11, preferably use one or more temperature-controlled area section 13, to assist the wall thickness concentricity controlling extrudate.And casing 11 is especially being best with two temperature-controlled area sections 13, and to be monitored the temperature of temperature control medium, to ensure that temperature is appropriate.
