Technical Field

[0001] The utility model relates to the technical field of phosphating production of bearings for railway freight cars, in particular to a multifunctional bearing phosphating water tank. Background Art

[0002] Phosphating is a surface treatment technology commonly used in bearing manufacturing. The process involves immersing metal parts in a solution containing phosphate. During the phosphating process, the iron on the metal surface reacts with the phosphate to form a porous iron phosphate film. Before and after the phosphating process, some auxiliary process flows are also required to ensure the final effect of phosphating.

[0003] For bearings used in railway freight cars, in order to meet the weight and load requirements of railway vehicles, each part of the bearing needs to be phosphated separately. During the phosphating process, various parameters such as the ratio of the phosphating solution, phosphating time, and phosphating temperature need to be accurately controlled. Different parts of the bearing need to use phosphating solutions with different ratios to ensure the reliability of the phosphating process.

[0004] However, for the bearings used in railway freight cars, a large number of steps in the phosphating process require manual assistance. In particular, the process of phosphating each component of the bearing separately is not equipped with equipment that meets the process requirements. Therefore, the reliability of the bearing phosphating process cannot be ensured. Utility Model Content

In particular, by setting up a phosphating liquid proportioning unit, the phosphating liquid of different concentrations required for each part of the bearing is proportioned and transported to different tanks; the phosphating process unit can detect the phosphating time and phosphating temperature of the bearing, and can adapt to the different requirements of different components for phosphating time and temperature; the bearing positioning unit can install and position the bearing, which solves the problem that the equipment in the prior art cannot meet the functional requirements of the production line when phosphating bearings for railway freight cars.

[0010] Furthermore, in order to ensure the uniformity of the phosphating liquid, the stirring tank includes: a tank body; a water inlet pipe and a liquid discharge pipe arranged on the top and bottom surfaces of the tank body, and a leak-proof material pipe installed at the bottom of the tank body; a stirring motor installed outside the tank body; and a stirring blade connected to the output shaft of the stirring motor and installed above the leak-proof material pipe.

[0011] Furthermore, in order to prevent the phosphating solution from leaking out of the stirring tank, the upper end of the anti-leakage material pipe is higher than the liquid level of the liquid inside the tank body.

[0012] Furthermore, in order to achieve stirring of the phosphating liquid while preventing the phosphating liquid from leaking out of the stirring tank, the blades of the stirring paddle extend downward along the upper end surface of the leakage-proof material pipe to below the liquid level in the tank body.

[0018] 1. The multifunctional bearing phosphating water tank of the present application is designed to meet the phosphating process requirements for railway freight car bearings: different bearing parts are phosphated separately to ensure the quality reliability of the final bearing product. A multifunctional bearing phosphating water tank is proposed, which can provide phosphating liquid with different proportions to different parts of the bearing, and realize the control of phosphating temperature and phosphating time to ensure the reliability of phosphating.

[0019] 2. The phosphating liquid proportioning unit of the present application realizes the function of proportioning phosphating liquids of different concentrations by setting several partitioned raw material bins, metering systems and metering bins on the stirring tank. At the same time, the leak-proof material pipe inside the stirring tank can prevent the phosphating liquid from leaking while stirring the phosphating liquid to ensure the uniformity of the phosphating liquid.

[0020] 3. The phosphating process unit of the present application realizes the control of temperature and phosphating time through a control module, wherein, since two position sensors with different horizontal heights are arranged on the side wall of the tank body, when the bearing is not immersed in the phosphating solution, the first position sensor can monitor the liquid level. If the liquid level is below the first sensor, it means that the phosphating solution is insufficient. At this time, the first position sensor alarms to remind to add the phosphating solution; when the bearing is immersed in the tank body, the phosphating solution level rises and the liquid level reaches the second position sensor. At this time, the second position sensor records the time when the liquid level reaches its horizontal position. When the liquid level triggers the position sensor time to reach a predetermined value, the alarm starts. At this time, the control module sends a signal to the cylinder that controls the lifting and lowering of the bearing positioning part, and the cylinder drives the bearing positioning part to leave the tank body.

[0021] 4.

If the liquid level is below the first sensor, it means that the phosphating solution is insufficient. At this time, the first position sensor 36 alarms to remind you to add the phosphating solution; when the bearing is immersed in the tank, the phosphating solution level rises and the liquid level reaches the second position sensor 37. At this time, the second position sensor 37 records the time when the liquid level reaches its horizontal position. When the liquid level triggers the position sensor time to reach a predetermined value, the alarm starts. At this time, the control module sends a signal to the cylinder 41 that controls the lifting and lowering of the bearing positioning part. The cylinder 41 drives the bearing positioning part to leave the tank, thereby finally realizing the control of the phosphating time.

[0042] Furthermore, the bearing positioning part 4 includes: a cylinder 41 installed on the slide rail 13; and a bearing bracket 42 connected to the output end of the cylinder 41.

[0044] Furthermore, the platform 423 and the extension platform 424 are triangular, and the three vertices of the triangle of the platform 423 and the extension platform 424 are installed with limiting columns 425.
