Wire drawing machine is widely used in industrial applications. It is widely used in machinery manufacturing, hardware processing, petrochemical industry, plastics, bamboo and wood products, wire and cable industries. This blog will continue to introduce the composition of LHD-450/13 high-speed al. alloy rod drawing machine.
5. Lubricating system and cooling system for main gear box and drawing oil tank
Transmission gears in the box are lubricated by oil pump with plate type of heat exchanger. Cooling system for drawing is an immerging and ejecting style. Drawing oil soaks 3/4 of drawing capstans and oil lubrication is ejected to drawing dies to enhance the using life of drawing dies. Cooling system includes oil lubrication recycling tank, filters, pipe type of heat exchangers, oil recycling pump. The temperature of lubricating and cooling oil is controlled to 35℃ ~ 50℃.
