Abstract
The utility model discloses a sizing sleeve with the diameter changeable. The sizing sleeve with the diameter changeable comprises a copper sleeve, wherein at least three gaps are arranged in one end of the copper sleeve along the axial direction, and the gaps divide the copper sleeve equally on the circumference of the copper sleeve. A lantern ring is arranged at the end of the copper sleeve with gaps, and a drawing device connected with the lantern ring is arranged at the other end of the copper sleeve. Besides, the width of each gap is 1-2 mm. The lantern ring and the copper sleeve have matching oblique planes respectively. The gaps in the copper sleeve are curved lines or straight lines or broken lines. The drawing device is composed of a draw bar connected with the lantern ring and a turning handle, wherein the draw bar is provided with a screw rod end connected with a threaded hole in the lantern ring. The sizing sleeve with the diameter changeable has the advantages that the inner diameter of the sizing sleeve can be changed in time according to production requirements in a production process, so that requirements of wall thickness changing and plastic raw material changing in a tubular product machining process are met.
Description
Technical field:
The utility model relates to a kind of calibration sleeve, particularly a kind of reducing metering sleeve of producing plastic tube.
Background technology:
As everyone knows; in the process of producing plastic tube, need the plastic pipe of hot melt stretching is cooled off with calibration sleeve; control simultaneously external diameter and the circularity of tubing; 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 to change another satisfactory calibration sleeve at production line; need to shut down; again start 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.
The utility model content:
In view of above-mentioned technical problem, the utility model provides a kind of reducing metering sleeve of producing plastic tube.It can change the calibration sleeve internal diameter in process of production as required.
Concrete technical scheme of the present utility model is as follows:
This reducing metering sleeve, comprise copper sheathing, it is characterized in that: the end on copper sheathing has three slits vertically at least, copper sheathing is divided equally at the circumference of copper sheathing in the slit: opening an apertured end at copper sheathing has the collar, at the other end of copper sheathing one stretching device that connects the collar is arranged, described every gap width is the 1-2 millimeter.
In the such scheme, the described collar has inclined-plane separately to cooperate with copper sheathing.
In the such scheme, the slit on the described copper sheathing is curve or straight line or broken line.
In the such scheme, described 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:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, reducing metering sleeve described in the utility model comprises copper sheathing 100, and the end on copper sheathing 100 has three slits 200 vertically at least, and every gap width is the 1-2 millimeter, and copper sheathing 100 is divided equally at the circumference of copper sheathing 100 in slit 200; An end that has slit 200 at copper sheathing 100 has the collar 300, and the stretching device 400 of a connection collar 300 is arranged at the other end of copper sheathing 100.The collar 300 has inclined-plane (500,501) separately to cooperate with copper sheathing 1.Slit 200 on the copper sheathing 100 is curve or straight line or broken line.Stretching device 400 is made of the pull bar 600 and the turning handle 700 that connect the collar 300, and the screwed hole 900 on the screw mandrel 800 ends connection collar 300 is arranged on the pull bar 600.In order to be fit to the flexible situation of different wall and different materials, can be by the collar 300 on stretching device 400 contractions or the stretching copper sheathing 100, when the collar 300 shrinks, the inclined-plane 501 of the inclined-plane 500 compression copper sheathings 100 of the collar 300, slit 200 on the copper sheathing 100 is compressed, the caliber of copper sheathing 100 diminishes, otherwise then the caliber of copper sheathing 100 becomes large.Because the melt pipe when producing on the inwall of copper sheathing 100, therefore can be produced the different tubing of same external diameter with the variation of the caliber of copper sheathing 100 by vacuum suction under different conditions, also can produce the tubing of various outer diameter under identical conditions.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
