Embodiment Construction

[0046] see Figure 1 to Figure 4, a kind of enameled wire drawing production method without special-purpose flat wire mold 21 of the present embodiment, comprises the following steps:

[0047] Step 1. Paying off wires: a plurality of bare wires 60 are led out from the wire paying-off assembly, and guided to the drawing assembly through the guide assembly;

[0048] The pay-off assembly is preferably a pay-off roller 11 wound with a bare wire 60, and the guide assembly is preferably a guide roller 12;

[0049] Step 2, wire drawing: the wire drawing component selects the existing flat wire mold 21 in stock, and the flat wire mold 21 adopts a mold whose width conforms to the design width of the flat wire and whose thickness is greater than the design thickness of the flat wire, and performs wire drawing processing on the bare wire 60;

[0050] Specifically, in step 2, the wire drawing assembly first uses the round wire die 22 to draw the bare wire 60 into the required round wire ...

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...
