Abstract
The invention discloses a method for producing a stretch-resistance enameled aluminum round wire, and relates to the technical field of producing enamelled wires. The method comprises the following steps of: annealing an aluminum wire; cleaning the aluminum wire with water; drying the aluminum wire and varnishing the aluminum wire, wherein the aluminum wire is cleaned by using diluents of the enamelled wire before the varnishing step; and carrying out the varnishing step instantly after the aluminum wire is dried again. A naked aluminum wire is cleaned by using the enamelled wire diluents to totally remove impurities of remained aluminum powder and the like of the aluminum wire stretched and attached on the surface of the naked aluminum wire, so that insulated paint is well connected with the naked wire; and in addition, the aluminum wire subjected to current leakage test after being stretched by 15 percent still has the leakage current below 10mA, so that the stretch-resistance performance of the aluminum wire is improved.
Description
Technical field
The present invention relates to the production technical field of enamelled wire.
Background technology
Along with the extensive use of enamelled round aluminium wire with and the continuous innovation of production technology; Increasing motor electric product user is in order to reduce production costs; All begun to attempt using aluminium to come Alloy instead of Copper; Comprise that some have relatively high expectations to enamelled wire or even harsh user, also hope to adopt the aluminum steel product.But this type of user's winding ratio is more special, and aluminum steel is not only wanted bending in winding process, also will be through very big tension force stretching, and it is bad that insulating varnish applies, and with directly causing insulating barrier to suffer serious destruction, thereby causes the turn-to-turn short circuit of motor product.
New production technology is in order to improve the stretch-resistance of paint film, to make the aluminum steel product of producing to satisfy enamelled wire is required harsh motor demand.
Summary of the invention
The purpose of this invention is to provide a kind of production technology that can improve the stretch-resistance of enamel insulated aluminium wire paint film, to satisfy the coiling of some special machines products.
The objective of the invention is to realize like this: comprise to aluminum steel anneal, water cleaning, oven dry and japanning step, it is characterized in that the diluent with enamelled wire cleans aluminum steel before the japanning step, after drying once more, get into the japanning step immediately.
The diluent of above-mentioned enamelled wire is that volume ratio is the cresols of 1 ︰ 1 and the intermixture that xylenes mixes formation.
The present invention is after bare aluminium wire is through traditional annealing and water cleaning; Increase mould one; Use separate duct filling enamelled wire diluent that it is carried out last cleaning; Utilization mixes the diluent that forms by cresols and xylenes will anneal afterwards that residual impurity such as aluminium powder thoroughly clean up, and be used for the coating of insulating varnish to obtain good bare wire.The impurity such as bare wire aluminium powder of the reason that Clicks here are few, and the saturation high tensile of paint film is stretched performance and obtained greatly to improve.
Advantage of the present invention: adopt the enamelled wire diluent that bare aluminium wire is cleaned; Can remove aluminum steel fully at the impurity such as residual aluminium powder that stretch attached to the bare aluminium wire surface; Make insulating varnish and bare wire can be good at being connected; Through still remaining on below the 10mA, improved the stretch-proof performance of aluminum steel to carrying out the leakage current test after the aluminum steel stretching 15%.
Embodiment
1, round aluminum rod is carried out cold drawn, obtain the aluminum steel that needs specification of producing.
2, aluminum steel being placed water temperature is that 50～80 ℃ deionized water cleans, with impurity such as the aluminium powder of removing the aluminum steel surface attachment, greasy dirts.
3, through aluminum steel is annealed, annealing temperature is 380～480 ℃, improves its crystal structure and recovers its soft state, also will remove lubricant and the greasy dirt that remains in the surface simultaneously effectively in this.
4, the aluminum steel after annealing is come out carries out water-cooled and handles, and utilizes and dry up the moisture that blower fan is blown away the aluminum steel surface, obtains dry aluminum steel.
5, cresols and xylenes are mixed formation enamelled wire diluent according to the volume ratio of 1 ︰ 1, for use.
Through the aluminum steel of super-dry before japanning; Through increasing by one mould on paint roller; The pipeline of this paint roller is incorporated into one separately only in the small containers of the filling enamelled wire diluent of automatic reciprocating circulation, under normal temperature condition, adopts the enamelled wire diluent that aluminum steel is cleaned; Carry out drying through baker immediately then, reach the purpose of getting rid of aluminum steel remained on surface impurity up hill and dale.
6, the aluminum steel after will drying is painted immediately and is cured; The baker inlet temperature is 300 ± 30 ℃; Curing temperature is 500 ± 50 ℃; Circulating fan is 1500～2200 rev/mins, and the waste discharge blower fan is 1000～1800 rev/mins, successively the processing of carrying out 5～7 road polyester-imide lacquers and 2～4 road polyamidoimide lacquers of circulation.
7,,, form aluminium enamel-covered wire and carry out take-up again with its surface-coated lubricating oil at last through the air-dry normal temperature that is cooled to.
So far, accomplish the whole process of production of enamelled wire.
Claims (2)
1. the production method of stretch-proof enamelled round aluminium wire with, comprise to aluminum steel anneal, water cleaning, oven dry and japanning step, it is characterized in that the diluent with enamelled wire cleans aluminum steel before the japanning step, after drying once more, get into the japanning step immediately.
2. according to the production method of the said stretch-proof enamelled round aluminium wire with of claim 1, the diluent that it is characterized in that said enamelled wire is that volume ratio is the cresols of 1 ︰ 1 and the intermixture that xylenes mixes formation.
