Abstract
The utility mode provides a vacuum sizing sleeve. The vacuum sizing sleeve comprises a plurality of circles of copper rings which are overlapped in sequence, a gasket is arranged each circle of copper ring, the copper rings and the gaskets form a round barrel, a first flange and a second flange are respectively arranged at two ends of the round barrel, the outer wall of the copper rings is further provided with a steel pillar, one end of the steel pillar is fixed on the first flange, and the other end of the steel pillar is fixed on the second flange. According to the sizing sleeve in the structure, the thickness of the round barrel is reduced, so that a good heat-conductive effect is achieved. Meanwhile, the steel pillar is capable of keeping the strength of the sizing sleeve, the sizing sleeve is not deformed in the use process, and the machined pipes are high in uniformity.
Description
Technical field
The utility model relates to the manufacture field of plastic tube, especially a kind of calibration sleeve for processing plastic tubing.
Background technology
Calibration sleeve is for processing plastic tubing, and its operated by rotary motion is in the back of extruding grinding tool, and inner at vacuum water tank, is used in conjunction with vacuum water tank, is used for finalizing the design and cooling off from the tubulose molten plastic that mould is extruded.The quality influence of the structure pipe moulding of calibration sleeve is larger.Pipe from mould is extruded through behind the calibration sleeve, can make pipe that certain cooling is arranged, and making again pipe can form one has more stable shaped pipe inside and outside wall chilling layer, so just can reach the work purpose of calibration sleeve.
The general pipe thickness of existing calibration sleeve is large, and the effect of heat conduction is bad, makes the sizing speed of plastic tube slow, affects speed of production; Some calibration sleeves inside is smooth not, makes the product appearance of producing that cut be arranged.
The utility model content
The utility model proposes a kind of vacuum sizing sleeve, solved the bad problem of calibration sleeve heat-conducting effect in the prior art.
The technical solution of the utility model is achieved in that
A kind of vacuum sizing sleeve, this vacuum sizing sleeve comprises the copper ring that some circles superpose successively, is provided with pad between described each circle copper ring, described copper ring and pad form a cylinder; The two ends of described cylinder are respectively arranged with the first flange and the second flange; Also be provided with steel column on the outer wall of described copper ring, an end of described steel column is fixed on described the first flange, and the other end is fixed on described the second flange.The calibration sleeve of this structure can reduce the wall thickness of described cylinder, so have good heat-conducting effect, described steel column can keep the intensity of calibration sleeve simultaneously, and in use can keep calibration sleeve indeformable, makes the tubing uniformity that processes high.
Preferably, the external diameter of described pad is greater than the external diameter of described copper ring, and described steel column runs through described pad.
Preferably, be provided with 1-3 described pad between described each circle copper ring.
Preferably, the end outer setting that described steel column is fixed on described the first flange has screw thread, and after described screw thread runs through described the first flange, is fixed on described the first flange by nut.
Preferably, described steel column is 10-50, distributes equably along the outer wall of described copper ring.
Preferably, also be provided with three-flange in the middle part of the described cylinder.
Vacuum sizing sleeve of the present utility model can reduce wall thickness, reaches good heat-conducting effect; Described steel column can keep the intensity of calibration sleeve simultaneously, and in use can keep calibration sleeve indeformable, makes the tubing uniformity that processes high.
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.
The utility model proposes a kind of vacuum sizing sleeve, as shown in Figure 1, this vacuum sizing sleeve comprises the copper ring 1 that some circles superpose successively, is provided with pad 4 between each circle copper ring 1, and copper ring 1 and pad 4 form a cylinder, and plastic pipe is namely at this cylinder interior sizing; Be respectively arranged with the first flange 2 and the second flange 3 at the two ends of described cylinder; Also be provided with steel column 5 on the outer wall of copper ring 1, an end of steel column 5 is fixed on the first flange 2, and the other end is fixed on the second flange 3.Can set out water ring on the second flange 3, with convenient calibration sleeve be lowered the temperature.
The metal material manufacturing of the general multiplex good heat conductivity of calibration sleeve, the working face that contacts with pipe should be smooth smooth, generally is Hard Chromium Coating.In illustrated preferred embodiment, the external diameter of pad 4 is greater than the external diameter of copper ring 1, and steel column 5 runs through pad 4, and namely pad 4 coats steel column 5 get up, and can reach the purpose of protection steel column 5, also makes product more attractive in appearance.
Between each circle copper ring 1 1-3 pad 4 can be set, in this preferred embodiment, be provided with one, namely copper ring 1 and pad 4 are alternately to superpose.Steel column 5 is fixed on the end on the first flange 2, and outer setting has screw thread, and after this screw thread runs through through hole 21 on the first flange 2, is fixed on the first flange 2 by nut.Also be provided with through hole 31 on the second flange 3, be used for fixing this vacuum sizing sleeve.
The quantity of steel column can be 10-50, distributes equably along the outer wall of copper ring 1, and its concrete quantity can be according to the concrete conditions such as the diameter design of copper ring 1.The cylinder middle part that forms at copper ring 1 also is provided with three-flange 6, also can be used for fixedly calibration sleeve, increases positioning intensity and precision.
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 2～5 times of the pipe diameter, 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.
