Abstract
The manufacturing process of fibre wound coreless rubber pipe comprises the sizing material heat refining of will work good, and extrudes inner glue layer through extruder, carries out semi-cure, carries out fiber then and twines kiss-coating slurry, drying simultaneously, through T type extruder head sheath hose outer, sends in the vulcanizing tank and vulcanizes.Characteristics of the present invention are to enter in the vulcanizing tank forward direction fiber spiral rubber hose in the second time to charge into 1～8kg/cm
2The air of pressure, two ends seal with seal then.The advantage of process of the present invention be good product quality, cost low, save the energy, operation simple, easy to operate, be easy to promote.
Description
The present invention relates to the rubber hose manufacturing process.
The method of the spiral rubber hose of China's production at present has been the core method or core centreless and usage has been arranged.It is to adopt the soft core of rubber to make mould that the core method is arranged, in carrying out glue extrude, semi-cure, through fiber winding, sheath hose outer and vulcanization process, make finished product.This method also needs the demoulding to remove the flexible glue core.Two during the last ten years the most of producers of China adopt this kind method always.The major defect of this method is: complex procedures, and equipment needed thereby is many, and labor strength is big, production cost height, energy consumption are big, and employed flexible glue core generally can only use about 10 times, just scraps, waste greatlyyer, and the glue core is easily pulled apart during the demoulding, causes substandard products or waste product.Therefore, some producers are to some small-bore sebific ducts in recent years, as φ 6mm～φ 10mm, adopt the centreless method to produce,, directly extrude, twine, vulcanize and make finished product promptly without the flexible glue core, the garden degree of sebific duct, adhesive force inequality, and to larger caliber, as φ 10～φ 51mm sebific duct still with there being the core method to produce.
The invention provides a kind of centreless pressurising method and produce the production technology of the large-bore hose of φ 6mm～φ 51mm.The present invention utilizes compressed air to play a supportive role, and replaces the soft core of rubber, thereby has saved the soft core of rubber, has simplified production technology and equipment, has alleviated working strength of workers again greatly.
Technology of the present invention is:
Behind mixing intact sizing material heat refining, extrude inner glue layer through extruder, send into vulcanizing tank then and carry out semi-cure, carry out fiber after the semi-cure and twine kiss-coating slurry simultaneously, send into then after hothouse, the drying again through T type extruder head sheath hose outer, after outer gum cover is intact, enter the pressurising operation, the sebific duct that packages crust is placed on the special workbench, at first adopt shutoff and clamping element, one end of good seal sebific duct, the other end are then chewed with inflation and are joined, and charge into 1～8kg/cm
2The air of pressure.Adopt shutoff and clamping element to seal after the pressurising, seal degree is as the criterion with air tight, at last the sebific duct after the inflation is sent into vulcanizing tank and vulcanizes, and after the taking-up, removes two ends and just makes finished product, and shutoff and clamping element are reusable.
Embodiment:
Sizing material behind the heat refining is extruded φ 8mm, 30.3 meters long inner glue layers through extruder, sends to the vulcanizing tank semi-cure, twines then, and the kiss-coating slurry is sent into hothouse again and placed 2～6 hours simultaneously, and temperature is 30～80 ℃.Taking out after extruder T connector sheath hose outer places then and charges into air on the dedicated, is diameter the end that sebific duct is inserted in the shutoff of φ 8mm at first, then clamps sealing with clamping element, and seal degree is as the criterion with air tight.The other end of sebific duct and inflation are chewed and are joined, and charge into 1～8kg/cm
2The air of pressure, and then adopt shutoff and clamping element sealing inflation end, send into vulcanizing tank inherence 3～6kg/cm then
2Down sulfuration 20～40 minutes of pressure, go out jar after, remove the termination and just make finished product.
Claims (3)
1, the present invention is a kind of manufacturing process of fibre wound coreless rubber pipe.This technological process is; With behind the sizing material heat refining of working good → through extruder extrude inner glue layer → send into carry out in the vulcanizing tank semi-cure → carrying out fiber twine in kiss-coating starch → send hothouse drying →, it is characterized in that through T type extruder head sheath hose outer → send in the vulcanizing tank once more and vulcanize:
A, before entering vulcanizing tank once more, in spiral rubber hose, charge into 1～8kg/cm
2The air of pressure.
B, in the shutoff of the two ends of the sebific duct that charges into air, and seal, with the holding tube internal pressure with clamping element.
2,, it is characterized in that the shutoff of sebific duct can be adopted hard core or the soft core of rubber according to the operation of stating in claim 1, b item year.
3,, it is characterized in that the external diameter of shutoff is consistent with the internal diameter of sebific duct according to the described operation of claim 2.
