Abstract
The utility model provides an external diameter sizing sleeve for a steel wire gauze skeleton composite tubular product. The external diameter sizing sleeve for the steel wire gauze skeleton composite tubular product comprises a cylindrical shell. A flange which is used for connecting a vacuum water tank is detachably connected with one end of the shell, a plurality of water inlets and vacuumized holes are evenly formed in the shell, and an inner core is arranged inside the shell. A plurality of through holes are evenly distributed in a side wall of the inner core, two ends of the inner core are respectively provided with water intake grooves, and two sides of the water intake grooves are respectively provided with a seal groove. The water intake grooves of the two ends of the inner core are communicated through a cooling flow pass. With the help of vacuumizing, the external diameter sizing sleeve for the steel wire gauze skeleton composite tubular product enables the surface of a tubular product and a sizing sleeve to be sealed and rubbed and meanwhile to inject cooling water into a cooling channel. The tubular product is attached to the sizing sleeve more tightly under the function of vacuum so that the friction coefficient of the tubular product and the sizing sleeve can be enlarged, the tubular product which is sized after frication and cooling is smooth in surface, and the adhesion of each layer material of composite layers is more firm.
Description
Technical field
The utility model relates to the manufacture field of plastic tube, especially a kind of compound plastic pipe external diameter calibration sleeve for the processing steel wire mesh frame.
Background technology
Wire net framework compound pipeline is to adopt the PE-RT(heat-proof polythene) material, through what extrude with the manufacturing process such as steel wire winding.Use the tubing of this manufacture of materials except having the original premium properties of heat-proof polythene, its intensity, hardness and rigidity also are provided greatly, all in every field extensive uses such as chemical industry, chemical fibre, electric power, food, medicine, municipal works, highway, railway, overpass and sewage disposals at home and abroad at present.
The use of calibration sleeve in the existing steel wire mesh frame plastic composite tube material production process also just is used at present core pipe sizing, and does not use calibration sleeve at the outer tube sizing.
The utility model content
The utility model proposes a kind of steel wire mesh frame plastic composite tube material external diameter calibration sleeve, make the composite pipe smooth in appearance that processes, steel wire mesh frame is smooth.
The technical solution of the utility model is achieved in that
A kind of steel wire mesh frame plastic composite tube material external diameter calibration sleeve, this calibration sleeve comprises a cylinder blanket, described shell one end removably is connected with for the flange that connects vacuum water tank, offers equably several water inlets on the described shell and several vacuumize the hole; Be provided with inner core in the described shell, several through holes that evenly distribute on the sidewall of described inner core, and offer respectively intake chamber at the two ends of described inner core, the both sides of described intake chamber arrange respectively seal groove; The intake chamber at described inner core two ends is communicated with by coolant flow channel.
Preferably, an end of described inner core is provided with flaring inclined-plane, so that tubing enters calibration sleeve.
Preferably, described coolant flow channel is evenly distributed on described interior in-core, and about the axis Rotational Symmetry of described inner core, reaches the purpose of even cooling.
Preferably, be connected with water inlet pipe on described each water inlet, described water inlet pipe is L-type.
Preferably, be provided with a plurality of installing holes on the described flange.
Preferably, the length of described inner core is the inner core internal diameter
Doubly
Steel wire mesh frame plastic composite tube material external diameter calibration sleeve of the present utility model makes tube surfaces and calibration sleeve seal friction by vacuumizing the hole, injects cooling water by described intake chamber in described cooling duct simultaneously.Tubing pastes tightlyer with calibration sleeve under the effect of vacuum, has increased the coefficient of friction of tubing and calibration sleeve, and is smooth through cooling and shaping tube surfaces out again after friction, and composite bed also because being squeezed so that layers of material bonding more firm.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of a kind of vacuum sizing sleeve preferred embodiment of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, steel wire mesh frame plastic composite tube material external diameter calibration sleeve of the present utility model comprises a cylinder blanket 2, removably is connected with for the flange 1 that connects vacuum water tank at an end of shell 2; Simultaneously offer equably several water inlets on the shell 2 and several vacuumize the hole; In the drawings, be connected with water inlet pipe 4 and water inlet pipe 6 on the described water inlet, be connected with vacuum tube 5 on the vacuum hole.In shell 2, also be provided with inner core 3, several through holes 10 that evenly distribute on the sidewall of inner core 3, this through hole is communicated with vacuum tube 5, is used for vacuumizing.Two ends at inner core 3 offer respectively intake chamber 8, in the both sides of intake chamber 8 seal groove 7 and seal groove 9 are set respectively.The intake chamber 8 at inner core 3 two ends is communicated with by coolant flow channel 11.
One end of inner core 3 is provided with flaring inclined-plane 12, formalizes so that tubing enters in the calibration sleeve.Coolant flow channel 11 is evenly distributed in the inner core 3, and about the axis Rotational Symmetry of inner core 3, can cool off equably the tubing of interior in-core.
In the utility model, be connected with water inlet pipe 4 or water inlet pipe 6 on each water inlet, these water inlet pipes are L-type, the one end is connected on the shell 2, is provided with the screw thread for connecting water pipe on the other end.
On flange 1, also be provided with a plurality of installing holes, Yi Bian be fixedly connected with this external diameter calibration sleeve.
The concrete length of calibration sleeve can be decided according to the conditions such as temperature of the raw-material performance of plastic tube, the speed of extruding pipe, cooling water.General calibration sleeve length is the pipe diameter
Doubly, and the diameter of calibration sleeve is less, and length is longer, and the diameter of sizing tube is larger, and length is shorter.The internal diameter size of calibration sleeve is the outside dimension of the plastic tube of moulding, generally this internal diameter size slightly than the internal diameter size of mouth mould more greatly, approximately large about 1%; The pipe outlet diameter of calibration sleeve is less than the pipe inlet diameter, and this numerical value needs have certain shrinkage value after the pipe cooling fixed, and this taper value, empirical data are generally about 8%.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
