Abstract
The utility model discloses a steel belt reinforced corrugated pipe which sequentially comprises an inner pipe, a steel belt framework and an outer corrugated pipe from inside to outside. The steel belt framework and the outer corrugated pipe are provided with spiral-surrounding peaks. The heights of the peaks are 1.3 times to 2 times the widths of the peaks. Positions, on the two sides of the peaks, of the outer corrugated pipe are provided with first reinforcing ribs. The heights of the peaks are 1.5 times the widths of the peaks. The four first reinforcing ribs are arranged on the two sides of the peaks in a pairwise mode. The outside of the steel belt framework is coated with a resin layer in advance. According to the steel belt reinforced corrugated pipe, the reinforcing ribs are additionally arranged in the corrugated pipe and the steel belt framework, the strength of the corrugated pipe is enhanced and the application range of the plastic corrugated pipe is wider.
Description
Technical field
The utility model relates to plastic film capicitor field, is specifically related to a kind of steel strip reinforced bellows.
Background technique

Plastic film capicitor is divided into two kinds, and a kind of is completely airtight, watertight, for example, carry coal gas, water heater for the propellant agent of carrier rocket; Band material continuous reeling for another kind, the bellows of common coiling is for the protection of cable, for example card phone machine, lathe, and the bellows of desk lamp is to sandwich in process of production steel wire.
Plastic film capicitor divides by the number of plies, can be divided into singel-ply bellows and double-ply bellows, wherein, singel-ply bellows is made simple, and cost is low, uses in static load environment more, can play the effect of bit shift compensation, and for being subject in the occasion of alternate load, multiselect is less by rigidity, the double-ply bellows of anti-fatigue performance excellence.
Limited due to plastics self intensity, therefore, the bellows intensity preparing is also limited, in prior art, occur utilizing steel band to increase the report of plastic film capicitor intensity, for example, notice of authorization number is that the model utility of CN202691342U discloses a kind of steel band reinforced spiral ripple pipe, comprises inner tube, outer bellows, between inner tube and outer bellows, be provided with steel strip corrugated skeleton, fixing by binding resin layer bonding between steel strip corrugated skeleton and outer bellows.
Although used steel band to strengthen plastic film capicitor, in the occasion higher to requirement of strength, existing steel strip reinforced bellows still can not meet usage requirement, needs further structure to be improved.
Model utility content
The utility model provides a kind of steel strip reinforced bellows, by set up stiffening rib in bellows, further increases the intensity of bellows, has expanded the use occasion of bellows.
A kind of steel strip reinforced bellows, comprise successively from the inside to the outside inner tube, steel belt framework and outward corrugated tube, described steel belt framework and outward corrugated tube be with the crest of spiral surrounding, the height of described crest is wave peak width 1.3～2 times, described outward corrugated tube is provided with the first stiffening rib in the both sides of crest.
When the utility model steel strip reinforced bellows is manufactured, first steel disc is rolled to bending, form the crest extending along steel disc length direction, obtain steel belt framework, then, by the inner tube of steel belt framework spiral winding, and in winding steel skeleton, peripheral injection moulding at steel belt framework forms outward corrugated tube, and in the steel strip reinforced bellows finally obtaining, steel belt framework is sandwiched between outward corrugated tube and inner tube.
The height of crest is 1.3～2 times of wave peak width, provide the height of enough crest for setting up the first stiffening rib, the first stiffening rib can have various ways, for example increase outward corrugated tube crest both sides thickness or form protuberance in the crest both sides of outward corrugated tube.
The excessive height of crest, also can cause weakening of ripple struction intensity, preferably, the height of described crest is wave peak width 1.5 times.
Can many first stiffening ribs be set in the both sides of crest, to increase the intensity of outward corrugated tube, consider the complexity of processing, preferably, described the first stiffening rib is four, is distributed between two the both sides of crest.
In order to protect steel belt framework in use not corroded by external environment, preferably, the outside of described steel belt framework is surrounded by resin layer in advance.
In the time manufacturing the steel strip reinforced bellows that the utility model provides, first, at the coated one deck resin layer of steel disc outer surface, then the steel disc that is enclosed with resin layer is rolled and form the crest extending along steel disc length direction, obtain steel belt framework.
The raw material of resin layer is consistent with the raw material of inner tube and outward corrugated tube, is convenient to fusion each other.
In order further to increase the intensity of bellows, can further improve the structure of steel belt framework, preferably, described steel belt framework is provided with the second stiffening rib of prebuckling in the both sides of crest.
In the time of processing steel belt framework, bend out the second stiffening rib at the crest place of steel belt framework, and then steel belt framework is wound around on inner pipe.
Preferably, described the second stiffening rib is four, is distributed between two the both sides of crest.The first stiffening rib and the second stiffening rib are bonded to each other, are of similar shape.
For the edge that prevents steel belt framework directly and inner tube connect, long-term use, causes the tube wall scratch of inner tube serious, preferably, the cross section of described steel belt framework has towards the opening portion of inner tube and away from the ridge of inner tube, and the both sides of described opening portion have the bending axial along inner tube.
The utility model steel strip reinforced bellows increases the structure of stiffening rib in bellows and steel belt framework, has increased the intensity of bellows, makes the application area of plastic film capicitor more extensive.
