[0029] The following will be combined with the attached Figures 1 to 3 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1~2 The present application shows an automatic phosphating device for railway freight car bearings, which includes: a transport section 1; a processing section 2 arranged directly below the transport section 1; a feeding section 3 arranged on the side of the processing section 2; wherein the processing section 2 includes: a first tank body 21, a second tank body 22, a third tank body 23 and a fourth tank body 24 arranged in sequence according to the phosphating process route, and the second tank body 22 includes a first sub-tank 221, a second sub-tank 222, a third sub-tank 223 and a cleaning device 25 installed in each sub-tank.

[0031] In one embodiment of the present application, the liquid in the first tank body 21, the third tank body 23 and the fourth tank body 24 is clean water, wherein the first tank body 21 and the fourth tank body 24 are equipped with a heating device, and after the clean water at room temperature is heated, the immersed bearing components are degreased and hot cleaned respectively; the liquid contained in the second tank body 22 is a phosphating liquid, which completes the phosphating treatment of the bearing components.

[0032] In the prior art, there is no dedicated production line designed for railway freight car bearings, so it is impossible to complete the phosphating of various bearing components separately at the same time. Usually, one production line is set up, and the liquid is replaced manually for many times to complete the phosphating of various components. The production efficiency is low, and the different concentrations of phosphating liquid remaining in the tank have a certain impact on the reliability of subsequent phosphating.

[0033] In this embodiment, since the second tank body 22 is aimed at different parts of the bearing, including the inner ring, the outer ring and the sealing seat, corresponding sub-slots are set, and a corresponding cleaning device 25 is provided to complete the cleaning of the fixed oxides generated during the phosphating process, so that the various parts of the bearing can be immersed in phosphating liquids of different concentrations at the same time, and the phosphating process is completed efficiently, which solves the problem in the prior art that the existing automatic phosphating device cannot realize the simultaneous phosphating of different parts of the bearing.

[0034] Furthermore, the cleaning device 25 includes: a shoveling part 251 arranged in the first sub-trough 221, the second sub-trough 222 and the third sub-trough 223, and a control module 252 arranged above the shoveling part 251, wherein the shoveling part 251 completes the movement in the horizontal direction and the vertical direction through the control module 252, and the shoveling part 251 completes the cleaning of the residue settled at the bottom of the sub-trough through the horizontal movement. After the shoveling part 251 moves to the other end of the bottom of the sub-trough, the control module 252 lifts the shoveling part 251 in the vertical direction, and finally brings the residue out of the sub-trough.

[0035] Furthermore, the control module 252 controls the up and down movement of the shoveling part 251 to ensure that when the shoveling part 251 descends to the bottom, the lower end surface of the shoveling part 251 is tightly fitted with the bottom surface of each sub-groove. When they are tightly fitted, the solid residue on the bottom surface of the sub-groove is removed through the relative movement between the bottom of the shoveling part 251 and the bottom surface of the sub-groove.

[0036] Furthermore, the side wall of the shoveling part 251 is provided with a hydrophobic groove 253. The hydrophobic groove 253 can reduce the resistance encountered by the shoveling part 251 during movement. The resistance of the shoveling part 251 is reduced by allowing liquid to pass through the hydrophobic groove 253, thereby preventing residue on the shoveling part 251 from falling off.

[0037] Furthermore, the control module 252 includes: upper and lower guide rails 2521 installed on both sides of the shoveling part 251; a horizontal guide rail 2522 installed on the upper end surface of the second trough body 22 and a first slide rail 2523 connecting the upper and lower guide rails 2521 and the horizontal guide rail 2522, wherein a driving motor is set to control the first slide rail 2523 to realize horizontal movement on the horizontal guide rail 2522, and then a driving motor is set to control the upper and lower guide rails 2521 to drive the shoveling part 251 to move up and down.

[0038] In a further embodiment, a serpentine tube heating device 26 is provided inside the first trough body 21 and the fourth trough body 24, wherein the serpentine tube heating device 26 in the first trough body 21 heats clean water to complete the degreasing treatment of the bearing; the serpentine tube heating device 26 in the fourth trough body 24 heats clean water to complete the thermal cleaning of the bearing, the purpose of which is to quickly evaporate the water and to maintain the oil penetration ability of the phosphating layer, which is convenient for oil immersion in the subsequent process.

[0039] Furthermore, the third tank body 23 includes an immersion area 231 and a drainage trough 232, wherein the immersion area 231 and the drainage trough 232 are separated by a partition 233 lower than the upper end surface of the third tank body 23. In the present embodiment, the immersion area 231 is used to hold clean water. When the phosphating components of the bearing enter the immersion area 231, the clean water can wash away the phosphating liquid remaining on the bearing. Thereafter, when the phosphating liquid remaining in the immersion area 231 reaches a certain concentration, the liquid level is raised by continuously adding clean water to the immersion area 231. The phosphating liquid remaining on the surface of the clean water will be finally discharged from the third tank body 23 through the partition 233 lower than the upper end surface of the tank body 23 as the liquid level rises.

[0040] Furthermore, the transport unit 1 includes: a support frame 11; a guide rail 12 installed along the arrangement position of the support frame 11; a slide rail 13 installed above the guide rail 12, and a drive motor 14, a hook 15 and a mounting frame 16 are arranged on the slide rail 13, wherein the drive motor 14 is installed on the slide rail 13 through a base, and the output end of the drive motor 14 is connected to the hook 15, and the mounting frame 16 is installed directly below the hook 15, and when the slide rail 13 moves to directly above the second slot body 22, the three drive motors 14 installed on the slide rail 13 are located directly above the first sub-slot 221, the second sub-slot 222 and the third sub-slot 223. In this embodiment, the drive motor 14 controls the up and down movement of the hook 15, thereby realizing the control of the mounting frame 16 hung on the hook 15. By pre-setting the drive motor 14, the control of the different lengths of time that each bearing component is immersed in the phosphating solution can be realized.

[0041] Furthermore, the material delivery part 3 includes: a first material delivery main pipe 31 arranged along the side wall of the tank body; a second material delivery main pipe 34; a third material delivery main pipe 35; a fourth material delivery main pipe 36; a material delivery branch pipe 32 connecting the tank body and the first material delivery main pipe 31 and a discharge valve 33 installed on the lower bottom surface of the tank body. In this embodiment, the discharge valve 33 is installed at the bottom of the tank body, which can completely discharge the liquid from the tank body when changing the liquid.

[0042] Furthermore, the feed branch pipe 32 includes: a first feed branch pipe 321 arranged along the side wall of the first trough body 21 to the upper end surface of the first trough body 21; a second feed branch pipe 322, a third feed branch pipe 323 and a fourth feed branch pipe 324 arranged along the side walls of the first branch trough 221, the second branch trough 222 and the third branch trough 223 to the upper end surfaces of the first branch trough 221, the second branch trough 222 and the third branch trough 223 respectively; a fifth feed branch pipe 325 connected to the first feed main pipe 31 and extending through the third trough body 23; a sixth feed branch pipe 326 arranged along the side wall of the fourth trough body 24 to the upper end surface of the fourth trough body 24, wherein the second feed branch pipe 322, the third feed branch pipe 323 and the fourth feed branch pipe 324 are respectively connected to the first feed main pipe 31 and the third feed branch pipe 325 is ... The second material delivery main pipe 34, the third material delivery main pipe 35 and the fourth material delivery main pipe 36, the first material delivery branch pipe 321, the fifth material delivery branch pipe 325 and the sixth material delivery branch pipe 326 are connected to the first material delivery main pipe 31. In this embodiment, since the solutions added to the first tank body 21, the third tank body 23 and the fourth tank body 24 are all clean water, the branch pipes corresponding to their infusion are connected to the same main pipe to improve the efficiency of material delivery; and the second tank body 22 needs to phosphate different parts of the bearing separately, so different material delivery pipes are set to meet the infusion requirements of phosphating solutions of different concentrations; in addition, for the pipelines that need to heat clean water and add phosphating solution, the feed inlets of their branch pipes are set at a position higher than the upper end surface of the tank body to prevent aging of the pipeline and increase its service life.

[0043] Furthermore, the branch pipe and the main pipe can be replaced separately when one part is damaged.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
