Description

Technical Field

[0001] The utility model belongs to the technical field of straight-through wire drawing machines, and particularly relates to a modular air-cooling structure of a straight-through wire drawing machine. Background Technique

[0002] Straight-through wire drawing machines are widely used in the metal wire processing industry, mainly used for stretching metal wires through dies to the required diameter. During the wire drawing process, due to the friction between the metal wire and the die and the high-speed operation of mechanical equipment, a large amount of heat will be generated inside the winding drum, resulting in an increase in the equipment temperature, which in turn affects the wire drawing efficiency and product quality. Therefore, how to effectively dissipate heat and keep the temperature inside the winding drum stable is an important issue for improving the performance of straight-through wire drawing machines and extending the service life of the equipment.

[0003] Most of the existing straight-through wire drawing machines use water-cooling or oil-cooling methods for heat dissipation. Although these heat dissipation methods can effectively reduce the temperature inside the winding drum, there are also some problems. The water-cooling system requires a large amount of water resources and needs to be maintained and the coolant replaced regularly. The oil-cooling system has problems such as complex maintenance, high cost, and poor environmental performance. Most traditional heat dissipation methods are overall cooling and it is difficult to adjust according to the heat dissipation requirements of different winding drums, resulting in high energy consumption and low heat dissipation efficiency. For this reason, we designed a modular air-cooling structure of a straight-through wire drawing machine to provide another technical solution for the above technical problems. Summary of the Utility Model

[0026] The lifting mechanism includes a second driving motor 10. At the bottom of the U-shaped frame 1, a second driving motor 10 is also bolted. The output end of the second driving motor 10 is fixed with a vertical threaded rod 11. The outer side of the vertical threaded rod 11 is threadedly connected with a vertical lifting block 12.
