Abstract
The utility model discloses a sizing sleeve for PP-R pipeline production, and belongs to the technical field of PP-R pipeline extrusion. The sizing sleeve comprises a sizing copper pipe sleeve and a sealing casing arranged outside the sizing copper pipe sleeve, wherein a group of vacuum absorption holes are formed in the sizing copper pipe sleeve at intervals, the left end of the sizing copper pipe sleeve is connected with a fixing bracket, the right end of the sizing copper pipe sleeve is connected with a cooling water spraying device through a connecting flange, and a fixing screw rod used for reinforcement is arranged between the connecting flange and the fixing bracket. With the adoption of the integral type sizing copper pipe sleeve, tooth imprints on the pipe surface due to decentraction of sizing discs can be prevented; the vacuum absorption holes of the sizing copper pipe sleeve are small, so that a pipe cannot be clamped in the sizing sleeve due to plastic expansion when water in a water tank is not full, and the debugging time is effectively shortened; and the contact area between the sizing sleeve and the surface of the pipe is larger, so that the surface of the pipe can be smoother due to long-term friction, the power consumption of a die is reduced, the pipe quality is improved, simultaneously, the production speed is higher, the equipment utilization rate is increased, and energy consumption is reduced.
Description
Technical field
The utility model belongs to PP-R pipeline extruding technology field, is specifically related to a kind of calibration sleeve for the PP-R pipe production.
Background technology
At present, known PP-R calibration sleeve sizing partly mostly is disc-type, and its sizing principle is that calibration sleeve is immersed in tank, simultaneously water and air in tank is vacuumized, and under negative pressure, completes the typing to the shaped plastics embryo.The disc-type calibration sleeve is superposeed and forms with one heart by some sizing copper sheets with holes, because copper sheet thickness is little, easily cause copper sheet torsional deformation or damaged, and during assembling, concentricity requirement is very high, and the disc-type calibration sleeve is in debug process, when in tank, water is discontented, cause the dried bombing or stuck of drawing, increase debug time; Disc-type calibration sleeve counterpart mould temperature requirement is high, and energy consumption is high, and easily causes the coarse or tooth of tube surfaces to print, and therefore limits extruded velocity in low scope.
The utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of calibration sleeve for the PP-R pipe production, this calibration sleeve not only is convenient to assembling, shorten debug time, and can improve extruded velocity, effectively solve tube surfaces because expanding or the poor tooth seal problem that causes of concentricity.
Described a kind of calibration sleeve for the PP-R pipe production, comprise sizing copper pipe cover and be equipped with the can in sizing copper pipe cover outside, described sizing copper pipe puts spaced one group of vacuum suction hole, it is characterized in that described sizing copper pipe cover left end is connected with fixed support, right-hand member is connected with cooling water injector by adpting flange, the fixedly screw mandrel that is provided for reinforcing between adpting flange and fixed support.
Described a kind of calibration sleeve for the PP-R pipe production, it is characterized in that described cooling water injector comprises the water outlet copper coin that is connected with adpting flange, with the bolted water inlet copper coin of water outlet copper coin, between described water outlet copper coin and water inlet copper coin, be provided with sealing ring, on the water inlet copper coin, water inlet is set, on the water outlet copper coin, sets out the mouth of a river.
Described a kind of calibration sleeve for the PP-R pipe production, is characterized in that described sizing copper pipe cover is an overall structure.
Above-mentioned a kind of calibration sleeve for the PP-R pipe production, comprise sizing copper pipe cover and be equipped with the can in sizing copper pipe cover outside, described sizing copper pipe puts spaced one group of vacuum suction hole, described sizing copper pipe cover left end is connected with fixed support, right-hand member is connected with cooling water injector by adpting flange, the fixedly screw mandrel that is provided for reinforcing between adpting flange and fixed support.The utility model is by adopting above-mentioned technology, and the diameter-setting equipment that present video disc is assembled changes to whole sizing copper pipe cover, effectively stops the decentraction problem between each sizing video disc, solve the tube surfaces tooth and print, and copper pipe is firm, and is not fragile; Monoblock type sizing copper pipe cover, the vacuum suction hole is little, and when water in tank was discontented, tubing can be not stuck in calibration sleeve because of plastic expansion, effectively shortens debug time; And it and tube surfaces contact area are larger, and long-term friction can make tube surfaces more bright and clean smooth, reduces the mould power consumption, promotes pipe workpiece quality, can have speed of production faster simultaneously, improves utilization rate of equipment and installations, saves energy consumption.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: the 1-fixed support, 2-is screw mandrel fixedly, 3-sizing copper pipe cover, 301-vacuum suction hole, 4-adpting flange, the 5-copper coin of intaking, 6-sealing ring, 7-water outlet copper coin, 8-screw, 9-can, 10-water inlet, 11-delivery port.
The specific embodiment
The utility model will be further described below in conjunction with Figure of description, but protection domain of the present utility model is not limited in this:
as shown in Figure 1, a kind of calibration sleeve for the PP-R pipe production, comprise the sizing copper pipe cover 3 of a monolithic construction and be equipped with the can 9 in sizing copper pipe cover 3 outsides, spaced one group of vacuum suction hole 301 on described sizing copper pipe cover 3, described sizing copper pipe cover 3 left ends are connected with fixed support 1, right-hand member is connected with cooling water injector by adpting flange 4, the fixedly screw mandrel 2 that is provided for reinforcing between adpting flange 4 and fixed support 1, described cooling water injector comprises the water outlet copper coin 7 that is connected with adpting flange 4, with the bolted water inlet copper coin 5 of water outlet copper coin 7, between described water outlet copper coin 7 and water inlet copper coin 5, be provided with sealing ring 6, on water inlet copper coin 5, water inlet 10 is set, on water outlet copper coin 7, set out the mouth of a river 11.
As shown in the figure, use procedure of the present utility model is: the end of tubing melt by sizing copper pipe cover 3 inner chambers flowed into, simultaneously to water-filled can 9 inside are vacuumized, make air 301 outflows from the vacuum suction hole of sizing copper pipe cover 3 inner chambers, the tubing melt of sizing copper pipe cover 3 inner chambers is attached on interior cavity wall, cooling formation tubing, for the ease of precooling, cooling water enters from the water inlet 10 on water inlet copper coin 5, through water inlet copper coin 5 and water outlet copper coin 7 form round cavity, 11 places form circular moisture film after water outlet.
The diameter-setting equipment that the utility model assembles by the video disc by present changes to whole sizing copper pipe cover, effectively stops the decentraction problem between each sizing video disc, solve the tube surfaces tooth and print, and copper pipe is firm, and is not fragile; Monoblock type sizing copper pipe cover, the vacuum suction hole is little, and when water in tank was discontented, tubing can be not stuck in calibration sleeve because of plastic expansion, effectively shortens debug time; And it and tube surfaces contact area are larger, and long-term friction can make tube surfaces more bright and clean smooth, reduces the mould power consumption, promotes pipe workpiece quality, can have speed of production faster simultaneously, improves utilization rate of equipment and installations, saves energy consumption.
