Abstract
The utility model relates to an air-filling bag for producing steel and rubber compound tubes, which is a hollow rubber barrel with a thin wall. The cross section of a main body of the gas bag is circular, and the longitudinal section of the main body is prismatic. The main body uses the center as reference to form bilateral symmetry. Both ends of the main body are bonded with reinforced rubber. One end of the main body is sealed and is provided with a traction pull ring, and the other end is provided with an air entering and discharging valve. The utility model has the advantages of strong applicability and sufficient air discharge, and compared with a ball rolling method and a plate scraping method, the utility model using an air bag stitching method is applied to occasions having regular and irregular frame steel tubes. The air bag discharges air gradually from the center to both sides so that the pressure of the inner side is larger than that of the outer side, and therefore, the utility model can completely discharge air in an interlayer so as to eliminate the defect that a lining layer is empty.
Description
The utility model system makes one of equipment special of steel and rubber compound tube.
At present, the manufacturing steel and rubber compound tube generally adopts rolling ball method or scraper plate method in operating in line with rubber, and its shortcoming is when meeting steel pipe caliber deviation, ovality deviation, surperficial convex-concave, manufactured good quality extreme difference.
The purpose of this utility model is that a kind of gas-filling bag that steel and rubber compound tube is made that is exclusively used in is provided.
The technical solution of the utility model is:
Will be with rubber bond by hollow and thin-walled rubber tube of the bonding one-tenth of the sheet rubber of specification requirement cutting.Its transverse section is circular, and longitudinal plane is a prismatic; The one end is shut, and the other end is equipped with the intake and exhaust valve.
Structure of the present utility model as shown in drawings.
Be the hollow and thin-walled rubber tube by the bonding air bag main body that forms 1 of sheet rubber, the transverse section is circular, and longitudinal plane is a prismatic, is the benchmark bilateral symmetry with the center, and two ends are stained with reinforced rubber 2, and traction draw ring 3 is shut and be equipped with to the one end, and the other end is equipped with air inlet and exhaust valve 4.
Working principle:
Air bag is placed in the lining packing element, enters together in the skeleton steel pipe that has coated tackiness agent, opens valve and inflates in air bag, and the thickest position of air bag central authorities at first is pressed on the lining packing element on the steel pipe inwall, simultaneously the air between steel pipe and packing element is pressed to both sides.Along with continuing to increase of air pressure, air bag compresses a while to continuous pressing in both sides and exhaust from the centre, finally make the lining packing element fully and steel pipe bonding.
Advantage of the present utility model:
1. adaptability is strong
Compare with rolling ball method, scraper plate method, be applicable to the occasion of skeleton steel pipe regular and irregular with the air bag pressing.When caliber deviation, ovality deviation, when surperficial convex-concave problems such as (as the weld seam of spiral welded pipe or the distortion of colliding with and causing) exists, preceding two kinds of methods are inapplicable, and the air bag rule is no problem.
2. exhaust is abundant
The exhaust of air bag is carried out gradually from the mediad both sides, because the unique design of air bag makes inboard pressure greater than the outside, thereby the air in the interlayer can be got rid of fully, thereby has eliminated backing layer this shortcoming of coming to nothing.
