Abstract
Description
Technical field:
The present invention relates to the expansion technique and the process units of heat-shrinkable tube, disclose a kind of heat-shrinkable tube and inflated continuous expansion method, the extension fixture that is adapted to this method also is provided simultaneously, belong to the processing technique field of Radiation Crosslinking Heat.
Background technology:
At present, the negative pressure expansion processing technologys that adopt in the expansion process of the crosslinking with radiation pyrocondensation draw more, in dilatation mold, realize the expanding and shaping of heat-shrink tube by outwards vacuumizing gas, in this production process, the inclined to one side wall phenomenon of heat-shrinkable tube is serious, and the tubing longitudinal extension rate of being processed reaches more than 20%, and is littler by 10% than actual product, this method speed of production is also slower, can only be reached for about 0.3 meter/minute.
Summary of the invention:
The invention provides a kind of heat-shrinkable tube inflatable expansion method, overcome that negative pressure expansion processing method production efficiency is low, the problem of poor product quality, improved the quality of production and the process velocity of heat-shrinkable tube.
The present invention also provides the heat-shrinkable tube that is adapted to this method to inflate continuous extension fixture.
Technical solution of the present invention is as follows: utilize high pressure gas to assist the shaping principle, after the heat-shrinkable tube thermoplastic, feed in it gases at high pressure in dilatation mold by the gases at high pressure inflation, handle through cooling and shaping again, by heating, expansion, cooling, traction, finish the expansion production process of heat-shrinkable tube.
The production equipment structure that adapts with the present invention is as follows:
On the platform of continuous dilator, be provided with heat-shrinkable pipe traction guide roller, between be sequentially with connecting gear, water-bath, oil bath heating cabinet and dilatation mold case and cooling and shaping chamber, wherein, motor is connected the charging of driving heat-shrinkable tube with the traction guide roller, heater links to each other with the oil bath case with water-bath by corresponding pipeline, heat-shrinkable tube is carried out the gradient increased temperature heating, be provided with heat-shrinkable tube hole enlargement mould in the dilatation mold case, two ends export connector and oil bath case and cooling and shaping chamber by sizing and are tightly connected, the feeding of controlling organization control heat-shrinkable tube, water, oil bath is heated and the gas assisted molding of gases at high pressure.
Good effect of the present invention is: utilize high pressure gas to assist the shaping principle, adopt malleation inflatable dilatation method, reduced the friction of tubing with the expansion sizing, the vertical shrinkage factor of product is less than 10%.Improved production efficiency, rate of expansion can reach more than 2～10 meters/minute.
Description of drawings:
Fig. 1 is a processing technology schematic diagram of the present invention.
Fig. 2 is the continuous extension fixture structure principle chart of the present invention.
The specific embodiment:
Embodiment 1
According to shown in Figure 1, utilize high pressure gas to assist the shaping principle, after 80～120 ℃ of heat-shrinkable tube heating, the feeding of 2～10 meters/component velocity, and the gases at high pressure that feed 0.03～0.05Mpar in dilatation mold by the gases at high pressure inflation, handle through 10～25 ℃ of cooling and shapings again,, finish the expansion production process of heat-shrinkable tube by heating, expansion, cooling, traction.
Embodiment 2
On the platform 1 of continuous dilator, be provided with heat-shrinkable pipe guide roller 2, between be sequentially with haulage gear 4, water bath 6, oil bath case 7 and dilatation mold case 9 and cooling and shaping chamber 10, wherein, motor 3 is led mechanism 4 with traction and is connected 11 chargings of driving heat-shrinkable tube, be provided with heater in water bath 6 and the oil bath case 7, in case, can carry out the gradient increased temperature heating to heat-shrinkable tube 11, be provided with heat-shrinkable tube hole enlargement mould 8 in the dilatation mold case 9, two ends are tightly connected with oil bath case 7 and cooling and shaping chamber 10 by sizing outlet connector 12, controlling organization 5 is by corresponding circuit and water bath 6, the control end of oil bath case 7 and haulage gear 4 connects, the feeding of control heat-shrinkable tube, water, oil bath is heated and the gas assisted molding of gases at high pressure.
