During use, the lubricating oil can be allowed to enter different filter tanks 31 by controlling the valve, so that when a single filter tank 31 is in use, the filter screen 311 in another filter tank 31 can be replaced and cleaned, thereby reducing downtime waiting time.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the wall reducing machine body 1 is provided with a heat exchanger 5 located at the bottom of the oil tank 13 on the outer side wall where the oil tank 13 is located, the end of the third oil pipe 43 away from the oil pump 41 is fixedly connected to the oil inlet port of the heat exchanger 5, and the oil outlet port of the heat exchanger 5 is fixedly connected with a return oil pipe 51, and the end of the return oil pipe 51 away from the heat exchanger 5 extends into the oil tank 13 and is connected with the oil tank 13, and the wall reducing machine body 1 is further provided with a cold water conveying mechanism 6 on the outside of the side where the oil tank 13 is located, and the cold water conveying mechanism 6 can convey cooling water into the heat exchanger 5 to perform heat exchange with the lubricating oil in the heat exchanger 5.

[0034] The lubricating oil output from the third oil pipe 43 will first enter the oil channel of the heat exchanger 5, and then flow back to the oil tank 13 through the return oil pipe 51. When the lubricating oil flows in the oil channel of the heat exchanger 5, the cooling water is transported to the water channel of the heat exchanger 5 through the cold water transport mechanism 6, so that the cooling water and the lubricating oil are heat exchanged in the heat exchanger 5, and the lubricating oil is cooled so that the lubricating oil flowing back to the oil tank 13 has good lubrication and heat dissipation effects.

[0035] like Figure 1 , Figure 4 and Figure 5As shown, the cold water delivery mechanism 6 includes a water tank 61, a return pipe 62 and a water delivery assembly 7. The water tank 61 is arranged outside the wall reducing machine body 1. One end of the return pipe 62 is fixedly connected to the top surface of the water tank 61. The end of the return pipe 62 away from the water tank 61 is fixedly connected to the water outlet port of the heat exchanger 5 and communicates with the heat exchanger 5.

[0036] When conveying cooling water to the water channel of the heat exchanger 5, the water pump 71 pumps out the cooling water in the water tank 61, and the cooling water enters the water channel of the heat exchanger 5 from the water inlet port of the heat exchanger 5 after being conveyed through the water pumping pipe 72 and the water outlet pipe 73. After the cooling water exchanges heat with the lubricating oil in the heat exchanger 5, it enters the reflux pipe 62 from the water outlet port of the heat exchanger 5, and flows back to the water tank 61 through the reflux pipe 62 to realize the recycling of the cooling water.

[0037] like Figure 4 and Figure 5 As shown, the water inlet port of the heat exchanger 5 is in a three-way shape, and a cooling supply pipe 52 connected to the inside of the heat exchanger 5 is fixedly connected to the water inlet port of the heat exchanger 5. The end of the cooling supply pipe 52 away from the heat exchanger 5 can be connected to an external tap water source, and a third solenoid valve 521 is provided on the cooling supply pipe 52.

[0038] When the temperature of the cooling water in the water tank 61 is too high and the cooling effect is poor, the second solenoid valve 731 can be closed and the third solenoid valve 521 can be opened to transport the external tap water source to the heat exchanger 5 through the cooling pipe 52 to exchange heat with the lubricating oil, thereby ensuring the cooling effect of the lubricating oil.

A fourth solenoid valve 81 is arranged on the water supply pipe 8, and the water outlet port of the heat exchanger 5 is in a three-way shape. A drainage pipe 53 connected to the external environment is also fixedly connected to the water outlet port of the heat exchanger 5, and a fifth solenoid valve 531 is arranged on the drainage pipe 53.

[0040] When the water temperature in the water tank 61 is not high, the cooling water will flow back into the water tank 61 through the return pipe 62 for recycling; when the water temperature in the water tank 61 is too high and the cooling temperature does not reach the set value, the water in the water tank 61 can be discharged and replaced; when the cooling water is discharged, the fifth solenoid valve 531 is opened, the first solenoid valve 621 is closed, and the cooling water will be discharged to the external environment through the drainage pipe 53; when replenishing the water tank 61, the fourth solenoid valve 81 is opened, the third solenoid valve 521 is closed, and the external tap water source is supplied to the water tank 61 through the cold replenishment pipe 52 and the water replenishment pipe 8, so as to realize the water replenishment work of the water tank 61.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, a temperature sensor 611 for detecting water temperature and a water level sensor 612 for detecting water level are provided in the water tank 61, and a controller 9 is provided on the top surface of the water tank 61.

[0042] The temperature sensor 611 and the water level controller 9 can respectively transmit the detected temperature data and water level data signals to the controller 9, prompting the controller 9 to control the first solenoid valve 621, the second solenoid valve 731, the third solenoid valve 521, the fourth solenoid valve 81 and the fifth solenoid valve 531 to open and close accordingly according to the input data, so as to realize automatic water replacement and water replenishment according to the water temperature and water volume in the water tank 61.

[0043] Working principle: When the workpiece is subjected to wall reduction and drawing work, the pump body 21 extracts the lubricant in the oil tank 13 and transports it to the oil replenishing pipe 12, and sprays the lubricant in the tank body through the oil nozzle 121, so that the wall reduction and drawing area of ​​the wall reduction machine body 1 is completely immersed in the lubricating oil, so that the lubricating oil fully lubricates the wall reduction die, reduces the wear of the wall reduction die, and increases its service life. At the same time, the metal scraps generated during the workpiece processing will also be suspended in the lubricating oil, thereby reducing the impact of the metal scraps on the operation of the equipment; when a large amount of metal scraps accumulate in the lubricating oil, the lubricant contained in the tank body can be transported to the filter tank 31 through the first oil pipe 32 for filtration. After the filter screen 311 completes filtering and removing impurities from the lubricating oil, the impurity-removed lubricating oil can be extracted through the oil pump 41, and the lubricating oil is transported to the oil tank 13 through the second oil pipe 42 and the third oil pipe 43, so as to realize the recycling of the lubricating oil; When the lubricating oil flows back to the oil tank 13 through the third oil pipe 43 for storage, the third oil pipe 43 will transport the lubricating oil from the oil inlet port of the heat exchanger 5 to the heat exchanger 5, and the lubricating oil will then flow out from the oil outlet port of the heat exchanger 5 and flow back to the oil tank 13 through the return oil pipe 51 for storage. In the process of the lubricating oil flowing through the heat exchanger 5, cooling water can be transported to the heat exchanger 5 through the cold water transport mechanism 6, and the cooling water and the lubricating oil exchange heat in the heat exchanger 5, thereby cooling the refluxed lubricating oil to ensure the lubrication and heat dissipation effects of the lubricating oil. When conveying cooling water to the heat exchanger 5 for heat exchange with lubricating oil, the cooling water in the water tank 61 can be pumped out by the water pump 71, and the cooling water is conveyed through the pumping pipe 72 and the outlet pipe 73, and enters the heat exchanger 5 from the water inlet port of the heat exchanger 5 to exchange heat with the lubricating oil, and flows out from the water outlet port of the heat exchanger 5 and then flows back to the water tank 61 through the reflux pipe 62, so as to realize the recycling of the cooling water in the water tank 61; when the temperature of the cooling water in the water tank 61 is too high and the cooling effect on the lubricating oil is not good, the external tap water source can be directly conveyed to the heat exchanger 5 through the cooling pipe 52 to ensure the cooling effect on the lubricating oil.
