Abstract
The utility model relates to a reducing sizing sleeve for producing plastic pipe, which comprises a copper sleeve. The utility model is characterized in that one end of the copper sleeve is provided with at least three clearances along an axial direction, and the clearances are uniformly distributed on the circumference of the copper sleeve; the end of the copper sleeve, which is provided with the clearances, is provided with a sleeve ring, and the other end is provided with a stretching device which is connected with the sleeve ring; the sleeve ring and the copper sleeve are provided with respective matched oblique surfaces; the clearances on the copper sleeve are curves, or straight lines, or fold lines; the stretching device is composed of a rotating handle and a draw rod which is connected with the sleeve ring, and the draw rod is provided with a guide rod end which is connected with a threaded hole on the sleeve ring. The utility model which has the advantages of changing the inner diameter of the sizing sleeve in time according to the production requirements in the course of production is suitable for the requirements of changing wall thickness at the time of processing pipe material and replacing plastic raw material.
Description
Technical field
The utility model relates to a kind of calibration sleeve of producing plastic tube, but particularly a kind of reducing calibration sleeve of producing plastic tube.
Background technology
Need in the process of production plastic tube at present the plastic pipe that hot melt stretches is cooled off with calibration sleeve; control the external diameter and the circularity of tubing simultaneously; but when product requirement is changed wall thickness and is changed the kind of plastics the tubing of processing; because the internal diameter of calibration sleeve is fixed; therefore just need on production line, change another satisfactory calibration sleeve; need to shut down; start again after the replacing; cause when shutting down and start shooting and to produce a considerable amount of useless pipes; also reduce production efficiency, increased production cost.
Summary of the invention
The purpose of this utility model is the fixing existing problem of internal diameter that solves the calibration sleeve of producing plastic tube in the prior art, but a kind of reducing calibration sleeve that can change the calibration sleeve internal diameter in process of production as required is provided.But the reducing calibration sleeve of plastic tube is produced in the utility model design, comprises copper sheathing, and it is characterized in that: the end on copper sheathing has three slits vertically at least, and copper sheathing is divided equally in the slit on the circumference of copper sheathing; Having at copper sheathing on the end in slit has the collar, and a stretching device that connects the collar is arranged on the other end of copper sheathing.The collar has inclined-plane separately to cooperate with copper sheathing.Slit on the copper sheathing is curve or straight line or broken line.Stretching device is made of the pull bar and the turning handle that connect the collar, and the screwed hole on the screw mandrel end connection collar is arranged on the pull bar.The utility model has the advantages that and in time to change the internal diameter of calibration sleeve in process of production according to production requirement, the demand of change wall thickness and replacing plastic raw materials when being fit to processing tubing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise copper sheathing 1 among the figure, it is characterized in that: the end on copper sheathing 1 has three slits 2 vertically at least, and copper sheathing 1 is divided equally in slit 2 on the circumference of copper sheathing 1; Having at copper sheathing 1 on the end in slit 2 has the collar 3, and a stretching device 4 that connects the collar 3 is arranged on the other end of copper sheathing 1.The collar 3 has inclined- plane 5,6 separately to cooperate with copper sheathing 1.Slit 2 on the copper sheathing 1 is curve or straight line or broken line.Stretching device 4 is made of the pull bar 7 and the turning handle 8 that connect the collar 3, and the screwed hole 10 on the screw mandrel 9 ends connection collar 3 is arranged on the pull bar 7.In order to be fit to the flexible situation of different wall and different materials, can be by the collar 3 on stretching device 4 contractions or the stretching copper sheathing 1, when the collar 3 shrinks, the inclined-plane 6 of the inclined-plane 5 compression copper sheathings 1 of the collar 3, slit 2 on the copper sheathing 1 is compressed, the caliber of copper sheathing 1 diminishes, otherwise then the caliber of copper sheathing 1 becomes big.Because the melt pipe when producing on the inwall of copper sheathing 1, therefore can be produced the different tubing of same external diameter with the variation of the caliber of copper sheathing 1 by vacuum suction under different conditions, also can produce the tubing of various outer diameter under identical conditions.
Claims (4)
- But 1, produce the reducing calibration sleeve of plastic tube, comprise copper sheathing, it is characterized in that: the end on copper sheathing has three slits vertically at least, and copper sheathing is divided equally in the slit on the circumference of copper sheathing; Having at copper sheathing on the end in slit has the collar, and a stretching device that connects the collar is arranged on the other end of copper sheathing.
- 2, but by the reducing calibration sleeve of the described production plastic tube of claim 1, it is characterized in that: the collar has inclined-plane separately to cooperate with copper sheathing.
