Problems solved by technology

[0004] Chinese application number 201810838561.7 discloses an enameled wire production process. By designing the original integral lubrication box as a detachable structure of a fixed block and a movable block, the groove can be directly exposed by removing the movable block when necessary, so that Even if the lubricating device is working, the felt can still be replaced at any time, and the whole process does not need to be shut down to operate, and the use effect is better, but it does not solve the problem of uncontrollable tension in the wire, which leads to low production efficiency of the enameled wire. Accordingly, the present invention Proposed a production method of DC variable frequency enameled wire

Embodiment approach

[0037] As a specific embodiment of the present invention, the tops of the No. 1 push rod motor 6 and the No. 2 push rod motor 7 are fixed with inflatable air bags 17, and two or more of the grinding pulleys 15 are provided on the side walls. Jet hole 18, described grinding pulley 15, No. 1 rotating shaft 14 and No. 2 rotating shaft are all cavity structures, and described inflatable air bag 17 communicates with the cavity of No. 1 rotating shaft 14, No. 2 rotating shaft through trachea, and described No. 1 rotating shaft 14. The cavities of the second rotating shaft are respectively connected with the cavities of the adjacent grinding pulley 15; during use, the burrs polished by the grinding pulley 15 may adhere to the surface of the copper wire, thereby affecting the subsequent painting process; by setting There is an inflatable air bag 17, and the inflatable air bag 17 is squeezed when the No. 1 push rod motor 6 and the No. 2 push rod motor 7 move back and forth, so that the ...

specific Embodiment approach

[0038] As a specific embodiment of the present invention, the outlet direction of the gas injection hole 18 is inclined to the side wall of the grinding pulley 15, and the gas ejected from the gas injection hole 18 is in oblique contact with the copper wire; during use, the gas injection hole 18 If it is set arbitrarily, it is easy to make the burr powder on the copper wire gather to the surface of the copper wire again, thereby causing secondary pollution; the gas injection hole 18 is set in an inclined state, so that the gas ejected from the gas injection hole 18 and the copper wire form an angle , so that the burr powder is blown to the side of the copper wire; the burr is blown to the side so that the copper wire will not be in contact with the burr powder again in the process of running the line, thereby reducing the probability of secondary pollution of the copper wire, thereby ensuring Production quality of copper wire.

Abstract

The invention belongs to the technical field of enameled wire production. The invention relates to enameled wires, in particular to a production method of direct-current variable-frequency enameled wires. A pay-off device used in the method comprises a bottom plate, a first plate and a second plate are fixed to the top end of the bottom plate. A drive motor is fixed to the side wall of the first plate. A first disc is fixed to the output shaft end of the drive motor. A first push rod motor is fixed to the side wall of the first disc. The driving motor is used for driving a first push rod motorto rotate, a second push rod motor is rotatably mounted on the side wall of the second plate, pressing discs are fixed to the output shaft ends of the first push rod motor and the second push rod motor correspondingly and used for pressing a winding reel, and a pressure sensor is fixed to the top end of the bottom plate. According to the invention, the moving speed of the copper wire is enabled to accord with wire arrangement regulations through adjustment of the driving motor, and the tension of the copper wire is adjusted through the arrangement of a third push rod motor, so that the copperwire is always subjected to uniform tension.

Description

technical field [0001] The invention belongs to the technical field of enameled wire production, in particular to a production method of DC frequency conversion enameled wire. Background technique [0002] DC frequency conversion technology is the most popular energy-saving technology at present. It refers to the process of controlling the speed of the rotor by adjusting the frequency of DC conduction. DC motor is used for DC variable speed. The DC motor only consumes power with one coil, while the AC frequency conversion has two coils, so the DC variable speed is more energy-saving than the AC frequency conversion. [0003] Enameled wire refers to a metal wire that uses insulating varnish as an insulating coating and is used to wind electromagnetic coils, also known as electromagnetic wire. It is a main variety of winding wire, which is composed of conductor and insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. However, it...
