During the operation of the water tank type wire drawing machine, a good cooling effect must be ensured. In fact, the temperature of the lubricating fluid is too high, resulting in a decrease in the lubricating effect, which is a common problem in water tank drawing operations. Moreover, when the lubrication effect decreases, the loss of the phosphating layer on the surface of the steel wire will increase, and the friction will increase, which not only increases heat generation, but also affects the service life of the mold. In severe cases, it may even cause whitening and cracking.
This is because under normal operating conditions, the lubricating fluid of the water tank type wire drawing machine will take away the heat generated by the deformation of the steel wire during the circulation process and act as a cooling fluid. If the cooling is insufficient, the temperature of the steel wire will increase, the strain aging time will be shortened, and the mechanical properties of the steel wire will deteriorate significantly, such as increased strength, decreased torsion value, and torsion cracks. In fact, in the actual operation process, high temperature will not only affect the performance of lubrication, mold and steel wire, but also cause the operating environment to deteriorate.
After analysis, it is found that the high temperature of the water tank type wire drawing machine is also related to the high temperature in summer, and it can be mainly attributed to the cooling capacity of the lubricating fluid circulation cooling system that cannot meet the increasing needs of equipment. In other words, the cooling system cannot adapt to a higher production scale and cannot quickly remove a large amount of heat. In order to solve this problem, it is necessary to further enhance the cooling capacity of the system and increase the processing capacity of the lubricating fluid cooling system, thereby reducing the temperature to an appropriate level.
After improving the cooling system, the operating temperature of the water tank drawing machine equipment has been significantly reduced. In this way, the use effect and service cycle of the lubricant are improved, the mechanical properties of the steel wire are greatly improved, and the consumption of the mold is also reduced. After comparison, it was found that after the cooling conditions were improved, the lubricant consumption per ton of steel wire was reduced, and the number of twists of the steel wire increased.
In general, during the operation of the water tank type wire drawing machine, the reasonable use of the cooling tower not only reduces the temperature of the entire lubrication system, improves the cooling conditions of the water tank type wire drawing machine, but also makes the surface quality of the steel wire better. Significant improvement. At the same time, abnormal problems such as whitening and cracking are also greatly reduced, and it also has a certain effect on improving the working environment of employees.
