Abstract
The invention aims to provide a stacked sizing sleeve for plastic pipe production, which can effectively solve the problems of complicated assembly/disassembly process, high production cost and the like in the prior art. The stacked sizing sleeve for plastic pipe production comprises two or more classification and sizing sleeves connected together, wherein a connection device is arranged between two adjacent classification and sizing sleeves; and the central axes of two adjacent classification and sizing sleeves are collinear. According to the invention, various plastic pipes which have different wall thicknesses or are made of different raw materials can be produced by using one length-variable sizing sleeve, and the deformation of the outer diameter of the pipe is prevented at the same time; the workload in the production as well as the production cost is reduced; and moreover, the stacked sizing sleeve also has a plastic pipe blank pre-cooling function.
Description
Technical field
The present invention relates to a kind of calibration sleeve that is used to produce plastic tube, particularly a kind of superposing type calibration sleeve that is used to produce plastic tube.
Background technology
In the plastic tube production technology, generally be macromolecule raw material material with molten condition, the injected plastic pipe mold, thus obtaining unshaped high temperature plastics pipe, plastic pipe enters cooling and curing in the vacuum tank.The porch of vacuum tank is provided with calibration sleeve, with the plastic pipe typing, determines the internal diameter and the wall thickness of tubing thus.When raw materials for production changed, the shrinkage factor of plastic pipe also can change, and the internal diameter of common calibration sleeve and length are changeless, so the external diameter of plastic pipe will change, and can not meet the goods requirement, therefore needed to change calibration sleeve.When factory need produce the different plastic pipe of wall thickness,, therefore also need to change calibration sleeve because the internal diameter and the length of calibration sleeve are changeless.That is to say that the plastic tube of producing same external diameter needs to join 2 or 3 calibration sleeves at least, needs in the production process repeatedly to dismantle and install, and has significantly improved production cost, causes waste.
Summary of the invention
The purpose of this invention is to provide a kind of superposing type calibration sleeve that is used to produce plastic tube, can effectively solve and remove and install trouble, production cost in the prior art than problems such as height.The present invention relates to a kind of superposing type calibration sleeve that is used to produce plastic tube, comprise the two or more classification calibration sleeves that link together, be provided with jockey between two adjacent classification calibration sleeves, the central shaft of two adjacent classification calibration sleeves is located along the same line.The edge of described superposing type calibration sleeve is provided with fixture.Described fixture is a fixed head.Described fixture is the water ring body.On the described water ring body according to nozzle is housed.Described jockey is arm-tie and pull bar.Described jockey is for being threaded.The present invention just can produce the different various plastic pipes of wall thickness difference or raw material with an adjustable length calibration sleeve, simultaneously can guarantee that the external diameter of tubing can not deform, both reduce the workload in producing, reduce production cost again, in addition, also has the pre-cooled function of plastic pipe.
Description of drawings
Accompanying drawing 1 is the cross-sectional view of dispersity of the present invention,
Accompanying drawing 2 is an overall structure schematic diagram of the present invention.
The present invention will be described below in conjunction with accompanying drawing.
The specific embodiment
The present invention is installed in the porch of vacuum tank, and vacuum tank inside is vacuum environment.
Comprise the two or more classification calibration sleeves that link together among the figure, the for example first classification calibration sleeve 1, the second classification calibration sleeve 2, the 3rd classification calibration sleeve 3, be provided with jockey between two adjacent classification calibration sleeves, the central shaft of two adjacent classification calibration sleeves is located along the same line.
The edge of described superposing type calibration sleeve is provided with fixture, the present invention is fixed on the porch of vacuum tank, calibration sleeve keeps vacuum state outward, and the calibration sleeve circumference has been covered with aperture or slit, the melt pipe once enter calibration sleeve by the inwall of vacuum suction at calibration sleeve on.
Described fixture can be fixed head 4, and fixed head 4 is provided with bolt hole 5, and available set bolt is fixed on the vacuum tank porch with calibration sleeve.
Described fixture can be the water ring body, and water ring body structure and fixed head are similar, but its inside is cavity, has cold water to flow into.According to nozzle is housed, in the work from then on cold water sprayed on the described water ring body, can be used to pre-cooled pipe.
Described jockey can be arm-tie 6 and pull bar, and the two ends of each classification calibration sleeve are respectively equipped with arm-tie, is evenly distributed with a plurality of circular holes 7 on the arm-tie, and two adjacent classification calibration sleeves rely on the pull bar that passes two arm-ties to be fixed.Jockey between the first classification calibration sleeve 1 and the second classification calibration sleeve 2 is to be conspicuous second pull bar 9 of arm-tie between arm-tie and first pull bar, 8, the second classification calibration sleeves 2 and the 3rd classification calibration sleeve 3.
Described jockey can be for being threaded, each classification calibration sleeve is all made an end outer surface screw thread, the threaded structure of other end inner surface, and the helicitic texture of two adjacent classification calibration sleeves is corresponding, can directly with rotation mode the two be threaded during installation.
The present invention when producing thin-wall pipes or using the less raw material of shrinkage factor to produce tubing, need that is to say that the sizing that needs is with two or more classification calibration sleeves with two-stage or the calibration sleeve more than the two-stage at work.With parts such as pull bar, arm-tie, nuts a plurality of classification calibration sleeves are fixed to the classification calibration sleeve back of the porch of close vacuum tank, and guarantee that each classification calibration sleeve is concentric.Calibration sleeve length is long more, and shaping time is also long more, and the thickness of the plastic pipe tube wall of producing is less, and tubing has gone out after the multistage calibration sleeve, fully cooling, and it is little influenced by vacuum, just can obtain required external diameter.Only need to regulate calibration sleeve length, just can produce same external diameter, the plastic pipe of different wall.
When producing thick-wall tube or using the bigger raw material of shrinkage factor to produce tubing, only get final product with the one-level calibration sleeve.Because one-level calibration sleeve length is shorter, the sizing time is shorter, and the thickness of the plastic pipe tube wall of producing is bigger, tubing has gone out after the one-level calibration sleeve, and tubing fails to cool off fully, even therefore the raw material shrinkage factor of using is bigger, be subjected to the influence of vacuum, air pressure can increase tube outer diameter.
