Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of wire drawing machine technology, specifically to a circulating cooling system for a wire drawing machine. Background Technology
[0002] Wire drawing machines are commonly used machining equipment in the metal wire products industry. They use wires of various materials and diameters as raw materials, and through cold drawing, produce finished or semi-finished wires of different diameters. Currently, the transmission mechanisms used in wire drawing machines on the market typically employ ordinary motors and reducers or V-belt drives. The most energy-efficient combination of a direct-drive water-cooled motor and a water-cooled frequency converter, while effective, lacks a sufficiently robust and energy-saving cooling system, exhibiting the following drawbacks:
[0003] 1. The existing wire drawing machine's cooling water requires a seepage-proof pit. Inadequate protection can lead to debris clogging the pipes, resulting in excessive seepage and evaporation, necessitating frequent water replenishment. Using antifreeze in the water tank is too costly, so softened water is the only option, and it's prone to freezing and damaging the pipes in winter. 2. An external professional water cooling system is expensive, wastes electricity, increases floor space costs, and excessively low temperature settings can cause condensation. Condensation inside the motor and inverter can lead to short circuits and burnout, requiring frequent inspections by professionals. Utility Model Content

[0005] This utility model proposes a circulating cooling system for a wire drawing machine, including a frame on which multiple water-cooled motors for wire drawing are arranged laterally. Each water-cooled motor is connected to a water-cooled frequency converter on one side to perform frequency conversion speed regulation control on the water-cooled motor.
[0006] The frame is equipped with a cooling water storage tank, a main cooling water pipeline for the motor, and a main cooling water pipeline for the water-cooled inverter. A circulating water pump and a radiator are installed between them to realize the circulation and cooling of the antifreeze coolant in the cooling water storage tank, the main cooling water pipeline for the motor, the main cooling water pipeline for the water-cooled inverter, and the radiator.

[0014] As a preferred embodiment of the above technical solution, the cooling water storage tank is a thickened and enlarged square tube of the frame base, so that it serves both as a frame support and a storage tank for antifreeze cooling water.
[0015] As a preferred embodiment of the above technical solution, the cooling water storage tank, the main cooling water pipeline of the motor, and the main cooling water pipeline of the water-cooled inverter are arranged laterally along the arrangement direction of the water-cooled motor and the water-cooled inverter.
