In a warm upsetting workshop, the stainless steel forming oil plays roles of lubricating warm upsetting equipment, cooling a cold upsetting die and punching rods. When the stainless steel wire is subjected to cold heading, lubrication and cooling are needed, and at the moment, cold stainless steel forming oil encounters the hot stainless steel wire to be heated and generate impurities. After a period of use, the oil temperature is continuously increased to reach equilibrium, the lubricating effect is reduced along with the increase of the temperature and the accompanying impurities, and thick oil sludge can be formed at the bottom of the oil tank through continuous deposition of the impurities.

However, when the oil sludge in the stainless steel forming oil is too much, the filter screen is often blocked, so that the die and the punching rod cannot be lubricated and cooled in time, and the die and the punching rod are damaged due to untimely cooling. And the temperature of the stainless steel forming oil after cooling the die is increased, and the cooling effect on the die after the stainless steel forming oil flows back to the cold header is poor. When the stainless steel forming oil tank is normally used for about half a year, the oil tank and the filter screen of the whole equipment are required to be cleaned and new stainless steel forming oil is required to be replaced, so that waste is caused, and the cost is increased.

Example 4
An embodiment 4 of a stainless steel insert warm heading production line for centralizing constant-pressure oil supply is shown in fig. 4, and an oil return pipe 6 and a cooling portion 5 are further defined on the basis of any one of the above embodiments.
Specifically, a temperature sensor 21 is disposed at one end of the oil return pipe 6 near the cooling portion 5, and the temperature sensor 21 is electrically connected to the cooling portion 5.
Specifically, the cooling portion 5 is a closed cooling tower, and the closed cooling tower includes a coil 501, a shower pipe 502, a grille 503, an air intake filter 504, an internal circulation water tank 505, and a fan 506. The temperature sensor 21 is electrically connected to a controller of the closed cooling tower.
The working principle or working process of the embodiment: the temperature sensor 21 monitors the temperature of the oil exiting from the cooling part 5, the temperature sensor 21 is electrically connected with the cooling part 5, and when the temperature of the oil is monitored to be too high, the temperature sensor 21 sends a signal to the cooling part 5 to enable the cooling part 5 to accelerate the refrigerating speed; when the oil temperature is monitored to be too low, the temperature sensor 21 sends a signal to the cooling portion 5 to slow down the cooling portion 5.
Oil circulates in the coil 501 of the closed cooling tower, heat is absorbed by the pipe wall of the coil 501, dry and cold air is pumped in from the outside through a fan 506 at the upper part of the cooler, the pumped air is filtered through an air inlet filter screen 504, and the dry and cold air discharges the heat absorbed by the pipe wall out of the tower; meanwhile, the spray water sprayed by the spray pipe 502 exchanges heat with the circulating oil in the coil pipe 501, when the temperature is too high, the spray system is automatically started, the spray pump sprays water on the wall of the hot coil pipe 501 through the spray pipe 502 to form a water film, a large amount of heat is absorbed through evaporation, evaporated water vapor meets the grille 503, water drops are formed on the surface of the grille 503, and finally the water drops fall back into the internal circulating water pool 505.
The beneficial effects of this embodiment are: the temperature sensor 21 is arranged on the oil return pipe 6 to monitor the temperature of oil in the oil return pipe 6, so that the cooled oil temperature can be kept to enter the cold header 1 at a proper temperature, and the cold header 1 can work normally. The closed cooling tower is used for cooling oil, and can be used for fully cooling the oil and simultaneously saving water resources, so that resource waste is avoided.
