Friends who have used the water tank type wire drawing machine equipment should know that sliding is a necessary basic condition during the operation of the equipment. Considering multiple aspects, for the water tank drawing machine, the principle of minimum sliding coefficient is the most reasonable.
This is because from the analysis of the operating state of the water tank type wire drawing machine, the mechanical properties, die consumption, and end break rate of the products produced by the commonly used drawing route and the process route formulated according to the principle of least sliding are compared. The principle of minimum sliding coefficient has obvious advantages.
Compared with dry wire drawing machines, water tank wire drawing machines have obvious absolute advantages in many aspects. Especially the advantages in lubrication and cooling are outstanding. At present, there are many high-performance steel wires of different specifications, such as steel cords, high-pressure hose wires, and aviation steel ropes, which are all produced using this equipment.
At the same time, based on the analysis of current development trends, the number of drawing passes of the water tank-type drawing machine equipment used in the future will gradually increase to adapt to the drawing of products with high total compression ratio. At the same time, the steel wire has good cooling and lubricating conditions during drawing. These advantages determine that it is most suitable for drawing thin-diameter, high-strength steel wires.
Based on the analysis of the current situation, the drawing passes of the water tank type wire drawing machine are about 18 to 22 times. With the increase in the performance requirements of the steel wire, the number of such passes can no longer be adapted to the production of high-strength fine steel wires, so it increases The number of drawing passes is the future development trend.
Of course, with the increase in the number of drawing passes of the water tank type wire drawing machine, more stringent requirements will be put forward for the process technology of the equipment in the future.
