Description

Technical Field

[0002] In the wire drawing process of the wire drawing machine, in order to improve production quality and production efficiency and reduce damage to production equipment and extend service life, it is usually necessary to lubricate and flush the base material before it is introduced into the wire drawing die with wire drawing liquid. In the existing wire drawing production system, a wire drawing liquid recycling loop is generally provided so that the wire drawing liquid can be circulated back and forth for lubrication and flushing, thereby reducing production costs and reducing the pollution of waste liquid to the environment.

[0003] However, the existing drawing liquid circulation cooling equipment is usually an open cooling box, which transfers the heat it carries through direct contact with the external air, thereby achieving cooling of the drawing liquid. However, the interaction between the drawing liquid and the external environment causes the high-temperature drawing liquid to have problems such as liquid volatilization, impurity intrusion, and component oxidation, which greatly increases the loss of the drawing liquid and reduces its performance parameters during recycling. Its service life is sharply reduced, and the lubrication and flushing effects of the drawing liquid are reduced, affecting the quality of the wire produced by the wire drawing. In addition, the single heat dissipation pipeline constructed by the prior art for the drawing liquid to pass is limited and blocked by the pipe wall, and the heat dissipation efficiency is weak, and the drawing liquid cannot be efficiently and fully dissipated.

The shunt pipeline 12 of the cooling component 1 is constructed with a variable diameter lumen in a manner that can continuously change the flow state of the wire drawing liquid, so as to increase the contact rate between the wire drawing liquid and the heat exchanger plate 2 and increase the heat exchange efficiency. The cooling component 1 provided in the present application constructs a shunt pipeline to split the wire drawing liquid into multiple branch liquid flows, so as to increase the contact area during the flow process and facilitate faster heat transfer, especially the structural design of the continuous change of the inner cavity cross-section size in the shunt tube body 12, so that the wire drawing liquid can continuously change the flow state when flowing in its tube cavity and accelerate the relative movement of the solution molecules, thereby improving the contact between the wire drawing liquid and the heat exchange plate 2, so that the wire drawing liquid can transfer heat with the heat exchange plate 2 faster and more fully and effectively reduce the liquid flow temperature, and the closed cavity environment constructed by the cooling component 1 can prevent the wire drawing liquid from interacting with the external environment, greatly avoiding the wire drawing liquid from being affected by the external environment and causing adverse reactions, component loss, and mixing of foreign matter, greatly improving the integrity of the wire drawing liquid during recycling, so that it can be recycled more permanently. The present application inlays heat exchange plates 2 on the tube wall of the shunt tube body 12 at intervals to accelerate the heat transfer of the wire drawing liquid in its tube cavity, so that the wire drawing liquid can achieve effective and sufficient heat transfer processing in the closed cavity environment. In addition, the present application is also provided with a heat dissipation component 4 that can perform secondary transfer of the heat transferred by the heat exchange plate 2, so as to efficiently and continuously ensure that the heat exchange plate 2 can maintain the bilateral temperature difference state required for its operation, so that the heat exchange plate 2 can continuously transfer heat for a long time.
