The purpose of the utility model can realize through following technical scheme:
A kind of tubing calibration sleeve comprises:
Copper pipe, its sidewall offers a plurality of through holes;
The first water storage ring, the one of which end is connected in copper pipe, and the internal diameter of the first water storage ring is consistent with the copper pipe internal diameter, forms a coaxial columniform inner chamber with copper pipe, and the madial wall of the described first water storage ring offers cooling bath;
The second water storage ring is located at the first water storage ring outside, and the outer wall of the inwall of the second water storage ring and the first water storage ring forms a water storage cavity, and the described second water storage ring-side wall offers first water inlet and second water inlet, and described first water inlet is communicated with water storage cavity;
The water ring lid is located at the end of the first water storage ring and two water storage rings, and is communicated with second water inlet, and water ring covers in the end of the first water storage ring and two water storage rings and forms annular moisture film.
The through hole of copper pipe sidewall is provided with at least 20, evenly is opened on the sidewall of copper pipe.
Described through hole is rectangular through-hole, waist through hole or manhole.
The cooling bath of the first water storage ring madial wall is a helicla flute, extends to the other end by an end of the first water storage ring.
The inwall of the described copper pipe and the first water storage ring adopts polishing.
The internal diameter of the described copper pipe and the first water storage ring is 16～2000mm.
Described copper pipe and length after the first water storage ring is connected are the copper pipe and the first water storage ring internal diameter 3～8 times.
The described second water storage ring is provided with mounting flange.
Compared with prior art, the utlity model has following advantage:
One, applied widely: novel high speed high accuracy sizing cover is applicable to the caliber of φ 16mm～φ 2000mm.Be applicable to the production of the tubing of different plastic materials, like PVC, PE, PP, PPR etc.
Two, simple and reasonable: novel high speed high accuracy sizing cover adopts combined module type structure, each several part advantages of simple.The oblique annular groove runner of optimizing of sizing, the copper pipe fluting of science.All guaranteed the efficient high-speed that tubing is produced.
Three, at a high speed, efficiently, high accuracy: the unsettled phenomenon of ripple and wall thickness in the tubing production process, can not occur, outer pipe wall is smooth, wall thickness is even, the copper pipe good heat conduction effect, sizing speed is fast, traction power loss is little.Can guarantee the tubing production of high-speed, high precision.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of tubing calibration sleeve comprises copper pipe 5, the first water storage ring 4, the second water storage ring 2 and water ring lid 1.The sidewall of copper pipe 5 evenly offers 32 rectangular through-hole 51, and these through holes 51 are dispersed throughout on the sidewall of whole copper pipe 5, calibration sleeve in use, copper pipe 5 extend in the tank that vacuumizes, and needs the tubing of sizing to be positioned at copper pipe 5.Because the copper pipe outside is a vacuum state, acts on tubing through the through hole 51 that is opened in sidewall, makes tubing be adsorbed on firmly on the inwall of copper pipe 5.
One end of the first water storage ring 4 is connected in copper pipe 5, and its internal diameter is consistent with the internal diameter of copper pipe 5, with the inner chamber of copper pipe 5 formation one concentric cylinder shape; The first water storage ring, 4 madial walls offer spiral cooling bath 41, extend to the other end by an end of the first water storage ring 4, spread all over whole madial wall; The second water storage ring 2 is located at the first water storage ring, 4 outsides; The outer wall of its inwall and the first water storage ring forms a water storage cavity 3, the second water storage rings 2 sidewalls and offers first water inlet 21 and second water inlet, 22, the first water inlets, 21 connection water storage cavities 3; Outside chilled water storage is in water storage cavity 3; Constantly flow through spiral cooling bath 41, tubing is cooled off, and prevent that tubing is bonded at the inwall of the first water storage ring 4 at the groove inside spin.And second water storage ring 2 be provided with mounting flange 23, play and vacuumize the fixing effect of tank.Water ring lid 1 is located at the end of the first water storage ring 4 and the second water storage ring 2, and is communicated with second water inlet 22, and water ring covers 1 and forms annular moisture film in the end of the first water storage ring 4 and the second water storage ring 2, and the size of moisture film can be covered through water ring and regulate.The inwall of the first water storage ring 4 and copper pipe 5 all carried out polishing; Guarantee its smoothness; Owing to offered spiral cooling bath 41 and through hole 51, guaranteed to act on the constant of pressure on the tubing, temperature, make tubing under the effect of hauling machine; Can fast and stable pass through calibration sleeve, guarantee the production of high-speed, high precision.
