Abstract
The utility model discloses a sizing device, which includes a vacuum water tank and a flange mounted on one side of the vacuum water tank, wherein a sizing sleeve and a bracket matched with the sizing sleeve are mounted in the vacuum water tank; the bracket is connected with the flange through a connecting rod; one end of the sizing sleeve is fixed with the flange; the other end of the sizing sleeve is fixed with the bracket; a plurality of through holes are formed on the sizing sleeve; and a plurality of water inlets and water outlets are arranged on the flange. The sizing device improves the dimensional stability and the attractive appearance of a pipeline, and avoids the problems that the ellipticity and the outer diameter of the pipeline are too big or too small.
Description
Technical field
The utility model relates to the pipeline industry, relates in particular to a kind of diameter-setting equipment.
Background technology
The steel wire mesh frame plastic composite tube road, as basic unit, the middle high-tensile steel wires that adopt are as enhancement layer with sandwich layer (plastic layer), and skin adopts plastic layer to coat, and the middle improvement resin that utilizes carries out bonding.In daily production process, the vacuum water tank at said plastic layer place has only cooling system usually and does not have the equipment of sizing, the principle of expanding with heat and contract with cold as everyone knows; The plastics hull-skin temperature of just having extruded is very high; Through after the cooling system cooling, plastic shrink, total external diameter can not better controlled; The pipeline ovality be will occur so, tubing outward appearance, total external diameter problem bigger than normal less than normal influenced.
Therefore, be necessary to provide a kind of diameter-setting equipment that solves the problems of the technologies described above.
The utility model content
The utility model technical problem to be solved is: a kind of diameter-setting equipment that solves tubing ovality and external diameter problem less than normal bigger than normal is provided.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of diameter-setting equipment; It comprises: vacuum water tank and be installed on the ring flange of vacuum water tank one side is connected through connecting rod between the support that calibration sleeve is installed in the said vacuum water tank and matches with calibration sleeve, said support and ring flange; One end of said calibration sleeve and ring flange be fixing mutually; The other end of said calibration sleeve and support be fixing mutually, and said calibration sleeve is provided with several through holes, and said ring flange is provided with several inlet openings and apopore.
As a kind of optimized technical scheme, said calibration sleeve is made of copper.
The beneficial effect of the utility model is: the side through in vacuum water tank is equipped with calibration sleeve, thereby improves the dimensional stability and the aesthetics of pipeline, avoids occurring pipeline ovality and external diameter problem less than normal bigger than normal.
Description of drawings
Fig. 1 is the structural representation of diameter-setting equipment.
Fig. 2 is the enlarged drawing at A-A shown in Figure 1 place.
Among Fig. 1 to Fig. 2: 1, vacuum water tank, 2, ring flange, 20, the inlet opening, 21, apopore, 3, calibration sleeve, 30, through hole, 4, support, 5, connecting rod.
The specific embodiment
See also Fig. 1 and Fig. 2, a kind of diameter-setting equipment, it comprises: vacuum water tank 1 and be installed on the ring flange 2 of vacuum water tank 1 one sides; The support 4 that calibration sleeve 3 is installed in the said vacuum water tank 1 and matches with calibration sleeve 3; Be connected through connecting rod 5 between said support 4 and the ring flange 2, an end of said calibration sleeve 3 and ring flange 2 be fixing mutually, and the other end of said calibration sleeve 3 and support 4 be fixing mutually; Said calibration sleeve 3 is provided with several through holes 30, and said ring flange 2 is provided with several inlet openings 20 and apopore 21.Said calibration sleeve 3 is made of copper.
During work, earlier vacuum water tank 1 inner air pressure is taken out outward, formed vacuum thereby make in vacuum water tank 1 and the calibration sleeve 3; Owing to take out less than the air pressure in the pipeline when vacuumizing, so the still standard pressure in the pipeline, pipe fitting at first passes through ring flange 2; Approach calibration sleeve 3 gets in the vacuum water tank 1 then; Water 20 gets into from the inlet opening of ring flange 2, and the plastic layer of pipeline is cooled off, and cooled water is discharged from the apopore 21 of ring flange 2; Form pressure differential between standard pressure in the said pipeline and the vacuum outside the pipeline; Thereby make the preformed circular pipe of extruding be connected to the inwall of calibration sleeve 3 tightly, thereby produce needed size, then the plastic conduit behind the sizing is cooled off it by the water spray of the shower nozzle in the vacuum water tank 1.The setting of through hole 30 can make water be sprayed onto the pipe surface in the calibration sleeve 3 on the said calibration sleeve 3, thereby can prevent that the tubing temperature is too high is bonded on the calibration sleeve.
The utility model is equipped with calibration sleeve 3 through the side in vacuum water tank 1, thereby improves the dimensional stability and the aesthetics of pipeline, avoids occurring pipeline ovality and external diameter problem less than normal bigger than normal.
Claims (2)
1. diameter-setting equipment; It is characterized in that: said diameter-setting equipment comprises: vacuum water tank and be installed on the ring flange of vacuum water tank one side is connected through connecting rod between the support that calibration sleeve is installed in the said vacuum water tank and matches with calibration sleeve, said support and ring flange; One end of said calibration sleeve and ring flange be fixing mutually; The other end of said calibration sleeve and support be fixing mutually, and said calibration sleeve is provided with several through holes, and said ring flange is provided with several inlet openings and apopore.
2. a kind of diameter-setting equipment as claimed in claim 1 is characterized in that: said calibration sleeve is made of copper.
