On-line wire drawing device for fine wire enamelling machine

Abstract

The invention discloses an online wire drawing device of a superfine wire enamelling machine. A wire drawing motor drives a constant-speed wheel and a constant-speed pulley to rotate via the transmission of a timing belt; the constant-speed pulley drives a first bridge pulley as well as an upper wire drawing pulley and a lower wire drawing pulley which are respectively and coaxially mounted together with an upper wire drawing stepped pulley and a lower wire drawing stepped pulley to rotate via the transmission of the timing belt; a second bridge pulley coaxially mounted with the first bridge pulley drives the upper wire drawing pulley and the lower wire drawing pulley respectively and coaxially mounted together with a second upper wire drawing stepped pulley and a second lower wire drawing stepped pulley to rotate via the transmission of the timing belt; a wire drawing mold frame and an outlet mold are mounted between the upper wire drawing stepped pulley and the lower wire drawing stepped pulley; a wire return wheel and a guide wheel are arranged under the constant-speed wheel; a varnished wire material is in tension connection with the upper wire drawing stepped pulley, the lower wire drawing stepped wheel, the constant-speed wheel, the wire return wheel and the guide wheel; the varnished wire material passes through the wire drawing mold frame when traveling between the upper wire drawing stepped pulley and the lower wire drawing stepped pulley. The online wire drawing device can ensure the online wire drawing normal running production of a superfine bare wire, and guarantees the quality and the performance of a superfine varnished wire.

Description

technical field [0001] The invention relates to enameled wire manufacturing equipment, in particular to an online wire drawing device in a fine wire enamelling machine. Background technique [0002] In the manufacturing process of enameled wire, for large and medium enameled wires, there is usually an online wire drawing process in the enamelled machine, that is, the bare copper wire is drawn to the thickness required by the user with the help of a wire drawing die and a wire drawing wheel, and then painted, baked, and taken up. and other processes, and for micro-enameled wires, due to the relatively small diameter of micro-enameled wires, it is easy to cause broken wires during the production process of enameled machines with large and medium wire drawing functions. Therefore, conventional micro-wire enameled machines do not have online wire drawing functions, and First use a special wire drawing machine to draw wires into finished products, and then use an enamelling machi...

[0002] In the manufacturing process of enameled wire, for large and medium enameled wires, there is usually an online drawing process in the enamelling machine, that is, the bare copper wire is drawn to the thickness required by the user with the help of a drawing die and a drawing wheel, and then painted, baked, and taken up. and other processes, and for micro-enameled wires, due to the relatively small diameter of micro-enameled wires, it is easy to cause broken wires during the production process of enameled machines with large and medium wire drawing functions. Therefore, conventional micro-wire enameled machines do not have online wire drawing functions, and First use a special wire drawing machine to draw wires into finished products, and then use an enamelling machine to process the fine wires into enameled wires. This method of manufacturing micro enameled wires that separates the wire drawing function from the production of enameled wires gives the quality and performance of enameled wires have a certain impact
