Adjustable wire cooling channel

Abstract

The invention belongs to the field of enamelled wire production equipment, and particularly relates to an adjustable wire cooling passage. The adjustable wire cooling passage comprises an introducing and taking frame and a horizontal connecting element, wherein the appearance of the horizontal connecting element is of a multi-section structure in sequential arrangement along a horizontal wire passing path of an enamelled wire; each section of horizontal connecting element is formed by two connecting arms and a separation plate; the enamelled wire advances to the position of the introducing and taking frame from an enamelling furnace wire discharge opening from the plate surface of one side of the separation plate, and is folded back through a direction changing wheel arranged on the introducing and taking frame and returns into the enamelling furnace through the plate surface of the other side of the separation plate; the plane formed by an enamelled wire feeding path is parallel to the plane formed by an enamelled wire return path; in the enamelled wire advancing direction, flanges are arranged at the front and back ends of each connecting arm; and base pulleys used for enabling the introducing and taking frame to move in the enamelled wire feeding direction are arranged at the bottom end of the introducing and taking frame. The adjustable wire cooling passage has the advantages that the installation is convenient and flexible; the cost is lower; and the on-line cooling efficiency and the cooling quality of the enamelled wire can be reliably ensured.

Description

technical field [0001] The invention belongs to the field of enameled wire production equipment, and in particular relates to an adjustable wire cooling channel for cooling enameled wires. Background technique [0002] The production process of enameled wire is: bare wire→painting→baking→cooling→repainting→baking→cooling→repainting→baking→cooling. After many cycles, the finished enameled wire is formed. In this process, the line temperature cooling link is very important. After the enameled wire is baked in an oven, the surface temperature is high, the paint film is soft, and the strength is low. If the cooling is improper, when the wire temperature is too low, the surface adhesion of the enameled wire will deteriorate, resulting in uneven coating defects in the subsequent surface painting process, which will easily lead to cracking of the paint film and wire breakage; when the wire temperature is too high, it will cause wire enameled wire Quality problems such as hemp ski...

Problems solved by technology

However, due to seasonal changes, the ambient temperature is very different. In winter, the room temperature is low, and the cooling speed of the enameled wire is faster under the same cooling process; while in summer, the room temperature is relatively higher, and the enameled wire needs stronger wind blowing or a relatively longer cooling cycle.

Since the wind speed of the fan in the air-cooled mode is not easy to adjust during use, on the one hand, how to accurately ensure that the enameled wire can reach a suitable cooling temperature becomes a problem; Product quality fluctuates greatly, and there are more waste products in the finished product line, which causes economic losses to the company
