Abstract
The invention provides a method and apparatus of hot contraction pipe gas-buffered continuous expanding. The hot contraction pipe directing roller is arranged on the platform of expanding machine; drawing machine, water-bath case, oil-bath case, expanding mold case and cool shaping case are arranged on the platform in order; control machine is connected with the control ends of water-bath case, oil-bath case and drawing machine by the corresponding wires; hot contraction pipe expanding mold is arranged on expanding mold case with its both ends sealing connected with oil-bath case and cool shaping case by caliber exit piece. It adopts high-pressure gas forming principle and positive pressure gas-filled expanding method to heat plasticity the hot contraction pipe, fills high-pressure gas into expanding mold, then cool shapes it. It finishes the expanding process after heating, expanding, cooling and drawing.
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.
