Enameled wire drawing production method without special flat wire die

Abstract

The invention relates to an enameled wire drawing production method without a special flat wire die. The enameled wire drawing production method comprises the following steps: 1, paying off is conducted; 2, wire drawing is conducted, specifically, an existing flat wire die in stock is selected as a wire drawing assembly, and the flat wire die is a die with the width meeting the designed width of a flat wire and the thickness larger than the designed thickness of the flat wire, and is used for conducting wire drawing machining on a bare wire; 3, calendaring is conducted, specifically,the bare wire is subjected to calendaring through a calendaring machine to obtain a flat wire of which the thickness accords with the designed thickness of the flat wire; 4, cleaning is conducted; and 5, annealing is conducted. According to the enameled wire drawing production method without the special flat wire die, by adopting the flat wire die with proper inventory in stock, products with set specifications can be produced when no special flat wire die exists, so that the production efficiency is greatly improved, the time cost and the die customization cost are reduced, the die cost is reduced by 30% or above, the production mode is a continuous drawing mode, and the production efficiency and the quality are not influenced.

Description

technical field [0001] The invention relates to the field of enameled wire drawing technology, in particular to an enameled wire drawing production method without a special flat wire mold. Background technique [0002] Enameled wire is a main variety of winding wire, which consists of two parts: conductor and insulation layer. The conductor is generally drawn with a copper rod to form a bare wire. Common bare wires have two specifications: flat wire and round wire. [0003] Compared with round wires, flat wires have many specifications. Round wires with the same diameter can be converted into 1000 types of flat wires. In the current production process, special molds are customized for flat wires of different wire gauges, and then flat wires of corresponding specifications are processed; because there are too many specifications of flat wires, each time an enterprise produces flat wires of one specification, it costs It is necessary to purchase a corresponding mold, so tha...

Problems solved by technology

However, the conversion order rate after delivery of samples is less than 20%, which affects the cost of enterprises is very high

The solution for most annealing furnaces is to use water sealing or steam generating equipment at one end of the furnace mouth, but when the annealing furnace starts to work, there is less water vapor in the annealing tube, and the air cannot be removed in time, and the bare wire is prone to oxidation, which affects the annealing effect , thus affecting the normal painting and baking of enameled wire
