Embodiment 1

[0035] For the fine vertically wound enamelled copper flat wire of the present embodiment, refer to the attached figure 1 , comprising a metal conductor core 17 and an insulating paint film layer 18 covering the outside of the metal conductor core 17; the insulating paint film layer 18 is a polyurethane resin layer, a polyesterimide resin layer, a polyamideimide resin layer Any one of them; the metal conductor wire core 17 is a copper conductor; the polyurethane resin layer is an insulating varnish layer formed by baking polyurethane varnish, and the polyesterimide resin layer is an insulating varnish formed by baking polyesterimide varnish In the film layer, the polyamide-imide resin layer is an insulating paint film layer formed by baking polyamide-imide paint.

Embodiment 2

[0037] For the manufacturing equipment of the fine vertically wound enamelled copper flat wire of the present embodiment, refer to the attached figure 2, including a water tank I3 for cleaning the bare copper round wire 1, and a fan I4 for drying the bare copper round wire 1 is installed in sequence at the outlet of the water tank I3, and is used for rolling the bare copper round wire 1 into a bare copper flat wire Roller calender 5, the output end of roller calender 5 is connected with flat wire drawing die 6 for trimming bare copper flat wire, and the output end of flat wire drawing die 6 is connected with bare copper flat wire for winding bare copper flat wire The wire reel 7 and the outlet end of the bare copper flat wire reel 7 are provided with a water tank Ⅱ8, and the outlet of the water tank Ⅱ8 is installed with a fan II 9 and an annealing furnace 10 for softening treatment in sequence, and the outlet of the annealing furnace 10 is provided with cooling and cleaning D...

Embodiment 3

[0039] The manufacturing process of the fine vertically wound enamelled flat copper wire of the present embodiment comprises the following steps:

[0040] 1. The bare copper round wire is put into a special roller calender, and is rolled into a flat wire once or twice according to the wide side and narrow side size of the nominal specification, and then it is trimmed by a flat wire drawing die The standard bare copper flat wire is collected in the bare copper flat wire reel;

[0041] 2. After the bare copper flat wire reel is put into the annealing furnace for softening treatment, the temperature during the annealing and softening treatment is controlled at 500°C. After cleaning with pure water, drying and cooling, the temperature of pure water is 70±5℃, and the air pressure of drying is ≥22Kpa. Then go through the wire wheel and enter the paint area to apply insulating paint multiple times, coat 12-16 layers, and bake in turn to form an enamelled copper flat wire that meets ...

Abstract

The invention relates to a fine vertically wound enamelled copper flat wire and its manufacturing equipment and manufacturing process, which is especially suitable for three-dimensional winding coils and belongs to the technical field of electrical machinery and equipment manufacturing in the wire and cable industry. The fine vertically wound enamelled copper flat wire includes a metal conductor core and an insulating varnish layer covering the outside of the metal conductor core. Including the following manufacturing processes: 1), cleaning, drying, calendering; 2), cleaning, drying, softening; 3), cleaning, drying, cooling; 4), painting, baking, oiling. The invention can prevent impurities and dust from being pressed into the surface of the copper flat wire, can completely remove the impurities and dust generated in the bare copper flat wire after trimming the flat wire drawing die to specifications, and solves the problem of the paint film on the product affected by the impurities and dust on the surface of the copper wire Adhesion issues.

Description

technical field [0001] The invention relates to a fine vertically wound enamelled copper flat wire and its manufacturing equipment and manufacturing process, which is especially suitable for three-dimensional winding coils and belongs to the technical field of electrical machinery and equipment manufacturing in the wire and cable industry. Background technique [0002] With its high slot fill rate, the flat coil has smaller volume and lighter weight with the same performance. Under the condition of the same volume, the coil performance is better. It has a larger surface area than the round conductor enameled wire, which can greatly reduce the skin effect and so on. , is widely used in high-frequency state, reducing high-frequency eddy current loss of coils, high heat dissipation, electromagnetic effects and other special performance requirements in electronic components of liquid crystal display panels, wireless networks, display monitors, CD-ROMs and other electronic and ele...
