Abstract
The utility model relates to a plastic-coated wire coil shaft generating no scrap iron, which is used for winding a transformer coil and belongs to the technical field of technology and tooling of a transformer. The plastic-coated wire coil shaft adopts the technical scheme as follows: the plastic-coated wire coil shaft comprises a steel wire coil shaft body (1) and an outer coating plastic (2); the outer coating plastic made of random copolymerized polypropylene is coated on the wire coil shaft body; and the outer coating plastic is in zero clearance fit with the steel wire coil shaft body. The plastic-coated wire coil shaft has the benefits as follows: a PP-R (PolyProperlene-Ramdom) plastic tube serving as a cold and hot water pipe in the building decoration engineering is shifted to the tooling of transformer manufacture, and the better anti-impact property of the outer coating plastic made of random copolymerized polypropylene can be fully utilized. The horizontal movement can be caused when a wire coil rolls on the wire coil shaft, obvious grooves cannot be formed on the outer coating plastic that is abraded, long-term running test shows that the effect is good and universality can be achieved, and the plastic-coated wire coil shaft adopts the same use method as the traditional wire coil shaft; in addition, the plastic-coated wire coil shaft has the characteristics of no generation of scrap iron, convenient use, low cost and the like, and radically solves the difficult problem that a conducting wire and the coil are polluted by trace quantities of scrap irons in recent decades.
Description
Affiliated technical field:
The utility model relates to a kind of plastic-coated wire coil shaft that does not produce iron filings fully, is used for the coiling of transformer coil, belongs to transformer technology and pattern assembly technical field.
Background technology:
Transformer manufacturing, especially 110 kilovolts of products that level is above, the inner cleaning of product is the key of qualified products.In the coil winding process, must rotate between (raw material) drum and wire coil shaft and the pay off rack three, the three all has wearing and tearing during rotation, and trickle, the micro-iron filings that wearing and tearing produce spread in coil region, are polluting coil always.People have solved less important wear problem between wire coil shaft and the pay off rack with various forms, and still, main heavy wear place is between drum and the wire coil shaft, the severe contamination coil.
The utility model content:
The utility model purpose provides a kind of plastic-coated wire coil shaft that does not produce iron filings fully, does not produce iron filings, and is easy to use, with low cost, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: a kind of plastic-coated wire coil shaft that does not produce iron filings fully comprises steel drum axis body and outsourcing plastics, the outsourcing plastic packets that the atactic copolymerized polypropene material is made is attached on the drum axis body, is that no gap cooperates between outsourcing plastics and the steel drum axis body.
Said atactic copolymerized polypropene is through being extruded as tubing, be called the PP-R plastic tube, be three type PA tubes again, adopt gas-phase copolymerization technology to make 5% left and right sides PE evenly polymerization (random copolymerization) and become pipeline material of new generation randomly in the strand of PP, as hot and cold water pipe, be used for building decoration engineering.
The outsourcing plastics are tubulose, adopt the PP-R plastic tube, are three type PA tubes again, and the external diameter of internal diameter and steel drum axis body is complementary, and will be sleeved on the steel drum axis body after the heating of outsourcing plastics, and the cooling back forms no gap and cooperates.
When needing to change the outsourcing plastics, just back off from steel drum axis body in outsourcing plastics heating back.
Plastic-coated wire coil shaft runs through the centre bore of drum, and two ends are supported by pay off rack.
The utility model plastic-coated wire coil shaft is to the frock (pay off rack) of all stringing disk-form of transformer industry, each producer of (lead) wire rod industry, and principle and performance all have general application, and just size changes.
The beneficial effects of the utility model: will be used for the PP-R plastic tube of building decoration engineering as hot water pipe, and be diverted to transformer and make frock, the outsourcing plastics that make full use of the atactic copolymerized polypropene material have good shock resistance.The move left and right phenomenon because drum rolls on wire coil shaft, the outsourcing plastics that are worn obvious groove can not occur, observe by long-term operation test, effect is fine, has versatility, and is identical with traditional using method, the present invention has and does not produce iron filings, easy to use, characteristics such as with low cost have thoroughly solved the difficult problem that lead, coil are in decades polluted by micro-iron filings.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: drum axis body 1, outsourcing plastics 2.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, a kind of plastic-coated wire coil shaft that does not produce iron filings fully comprises steel drum axis body 1 and outsourcing plastics 2, and the outsourcing plastic packets that the atactic copolymerized polypropene material is made is attached on the drum axis body, is that no gap cooperates between outsourcing plastics and the steel drum axis body.The outsourcing plastics are tubulose, adopt the PP-R plastic tube, are three type PA tubes again, and the external diameter of internal diameter and steel drum axis body is complementary, and will be sleeved on the steel drum axis body after the heating of outsourcing plastics, and the cooling back forms no gap and cooperates.When needing to change the outsourcing plastics, just back off from steel drum axis body in outsourcing plastics heating back.
Plastic-coated wire coil shaft runs through the centre bore of drum, and two ends are supported by pay off rack, and during work, what drum and wire coil shaft rotated wearing and tearing on pay off rack is special plastics, and no iron filings produce.
Claims (2)
1. plastic-coated wire coil shaft that does not produce iron filings fully, it is characterized in that comprising steel drum axis body (1) and outsourcing plastics (2), the outsourcing plastic packets that the atactic copolymerized polypropene material is made is attached on the drum axis body, is that no gap cooperates between outsourcing plastics and the steel drum axis body.
2. the plastic-coated wire coil shaft that fully do not produce iron filings according to claim 1 is characterized in that plastic-coated wire coil shaft runs through the centre bore of drum, and two ends are supported by pay off rack.
