Roller type enameled wire surface lubricant coating device and its application

Abstract

The invention discloses a roll shaft type varnished wire surface lubricant coating device and the application of the roll shaft type varnished wire surface lubricant coating device. The roll shaft type varnished wire surface lubricant coating device comprises a fusion unit used for converting solid lubricant into liquid lubricant through heating fusion and a coating unit used for evenly coating the surface of a varnished wire with the lubricant. The solid lubricant is heated through the fusion unit, felt is coated with the liquid lubricant through a roll shaft, the liquid lubricant permeates the felt, and the surface of the varnished wire is coated with the liquid lubricant; problems, caused by 120 # solvent, of environmental pollution, potential safety hazards and cost increase are avoided, the cleanness of the lubricant and the evenness of lubricant coating are guaranteed, the surface smoothness of the varnished wire is improved, the friction force between the varnished wire and a tool device is reduced, the requirement for an efficient, continuous and automatic varnished wire winding technology can be satisfied, smooth paying off in the process of winding is guaranteed, and the device and the application are particularly suitable for manufacturing the varnished wire with the diameter ranging from 0.07 mm to 1.0 mm.

Description

technical field [0001] The invention relates to the technical field of enameled wires, in particular to a roller-type enameled wire surface lubricant coating device and its application. Background technique [0002] Enameled wire 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. There is friction between the enameled wire and the tooling equipment (guide wheel, mold, winding machine parts, etc.) Lowest possible coefficient of friction. In the 1980s, quite a few factories used paraffin dissolved in gasoline for surface lubrication. The slipperiness of enameled wire has been greatly improved, but there are still many problems. In particular, with the continuity of enameled wire production and the automation of winding, it is required that the amount of rewinding and unwinding of the single wire reel should be as large as possible to improve production effic...

Problems solved by technology

The use of 120# solvent oil has the following disadvantages: (1) a large amount of 120# solvent oil needs to be used, and 120# solvent oil is easy to volatilize, and emits a pungent smell, which pollutes the environment

(2) The ignition point of 120# solvent oil is low, and the safety factor is low, which is prone to hidden dangers such as fire; deflagration accidents are prone to occur during the production process, and there are hidden dangers in production safety

(3) A large amount of 120# solvent oil is used to increase the production cost of the product

However, the oiling device uses a rubber block to scrape off the lubricating oil wax, and its precision is very poor. It is difficult to ensure the uniformity of the oiling lubricant coating, which in turn affects the surface smoothness of the enameled wire, and it is difficult to reduce the friction between the enameled wire and the tooling equipment.
