[0002] Steel reacts with oxygen in the air at high temperatures to form oxide scale. For example, before hot rolling, a primary oxide scale of 1 to 3 mm thick will form on the surface of the steel billet in a heating furnace at 1100°C to 1300°C. During hot rolling, a secondary oxide scale will form on the surface of the steel billet when it comes into contact with water and air. Tertiary oxide scale will also be produced during finishing rolling.

[0003] The presence of oxide scale on the surface of steel parts is carried into the interior of the forging during the forging process, which deteriorates the quality of the forging. At the same time, the oxide scale accumulates inside the mold during the forging process, causing mold wear. Therefore, the oxide scale on the surface of steel parts needs to be removed. Using ultrasonic vibration to remove oxide scale from steel parts is one way to remove oxide scale.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] Example 1

[0034] like Figure 1 、 Figure 2As shown, the device for removing oxide scale from steel parts comprises: a housing 10, a cleaning tank 11 filled with a cleaning liquid is provided at the upper end of the housing 10, an ultrasonic generator 12 and an ultrasonic transducer 13 are provided at the bottom of the housing 10, the ultrasonic generator 12 generates a high-frequency electrical signal, and the ultrasonic transducer 13 converts electrical energy into mechanical energy, exciting ultrasonic vibrations, causing the cleaning liquid to produce cavitation effects and thermal effects, thereby stripping oxide scale from the steel parts, and a cleaning basket 50 is provided inside the cleaning tank 11, and the steel parts are placed in the cleaning basket 50;

[0035] The rotating assembly includes a motor 21 mounted on the outside of the housing 10. The output end of the motor 21 is connected to a gear 1 22. The gear 1 22 is engaged with a gear 2 23 mounted on the upper portion of the cleaning basket 50.

[0036] The lifting assembly includes a plurality of electric push rods 31, which are assembled on the outside of the housing 10. The output end of the electric push rod 31 is connected to an outer ring 33, and an inner ring 32 is rotatably engaged with the outer ring 33. The upper end of the inner ring 32 extends upward to form a convex ring 34. The height position of the cleaning basket 50 is changed by controlling the overall length of the electric push rod 31. Specifically, the overall length of the electric push rod 31 increases, driving the cleaning basket 50 to move upward, and the overall length of the electric push rod 31 decreases, driving the cleaning basket 50 to move downward.

[0037] The convex ring 34 supports the gear 2 23 , and the motor 21 drives the cleaning basket 50 to rotate through the meshing gears 1 22 and 23 , thereby assisting in shedding the oxide scale separated from the steel parts by ultrasonic vibration.

[0038] The method for removing oxide scale from steel parts comprises the following steps:

[0039] S1. Placing steel parts: placing the cleaning basket 50 containing the steel parts in the cleaning tank 11, wherein the gear 2 23 is meshed with the gear 1 22;

[0040] S2. Adjust the position of the cleaning basket 50: The electric push rod 31 drives the cleaning basket 50 downward through the outer ring 33, the inner ring 32, the convex ring 34, and the second gear 23 until the steel part is below the liquid surface;

[0041] S3, rotation and separation: the motor 21 is powered on and started, and the cleaning basket 50 is driven to rotate through the gear 1 22 and the gear 2 23, thereby assisting in the shedding of the oxide scale separated from the steel part by ultrasonic vibration;

[0042] S4. Steel parts are taken out: the electric push rod 31 drives the cleaning basket 50 to move upward through the outer ring 33, the inner ring 32, the convex ring 34 and the gear 2 23 until the steel parts are above the liquid surface. The motor 21 drives the cleaning basket 50 to rotate to dehydrate the steel parts and then take them out.

[0043] The device for removing oxide scale from steel parts in the present technical solution uses ultrasonic vibration to remove oxide scale from steel parts. At the same time, the rotating component drives the cleaning basket 50 to rotate in the cleaning tank 11, so that the steel parts move in the cleaning liquid. The steel parts are impacted by the cleaning liquid, which accelerates the shedding of oxide scale on the surface of the steel parts and improves the effect of shedding oxide scale on the steel parts.

[0044] The setting of the lifting component: 1. Supporting the rotating cleaning basket 50; 2. Changing the height position of the cleaning basket 50 to facilitate taking the cleaning basket 50 out of the cleaning tank 11 or placing the cleaning basket 50 into the cleaning tank 11; 3. Cooperating with the rotating component 20, after the lifting component drives the cleaning basket 50 to move upward until the steel part is above the liquid surface, the rotating component 20 drives the cleaning basket 50 to rotate to perform the steel part dehydration operation.

[0045] like Figure 2 As shown, the cleaning basket 50 is provided with a filter hole 51 and an opening 52. The setting of the filter hole 51 and the opening 52 facilitates the cleaning liquid to enter the interior of the cleaning basket 50 to remove the oxide scale of the steel parts; at the same time, it is convenient for the fallen oxide scale to be discharged from the cleaning basket 50; at the same time, the setting of the opening 52 facilitates the placement of steel parts in the cleaning basket 50 or the removal of steel parts from the cleaning basket 50. It should be noted that the rotation speed of the cleaning basket 50 should not be too fast to avoid throwing the steel parts out through the opening 52.

[0046] In order to further improve the effect of oxide scale removal, Figure 1 As shown, it also includes a liquid circulation component 40, which includes a tube body 41. The two ends of the tube body 41 are respectively connected to the two ends of the cleaning tank 11. A water pump 42 is provided on the tube body 41. When the water pump 42 is started, the cleaning liquid in the cleaning tank 11 flows through the left end of the tube body 41, the water pump 42, and the right end of the tube body 41 into the interior of the cleaning tank 11, forming a liquid circuit. The specific circulation path is as follows Figure 1 As shown by the arrows in the figure, the arrangement of the liquid circulation component 40 keeps the cleaning liquid in a flowing state, impacting the oxide scale of the steel parts and improving the effect of removing the oxide scale;

[0047] At the same time, the liquid circulation component 40 cooperates with the rotating component 20, and the flowing cleaning liquid impacts the rotating cleaning basket 50, that is, the steel parts at the same height but different angles in the cleaning basket 50 are washed, thereby improving the oxide scale shedding effect of the entire steel parts.

[0048] like Figure 1As shown, the length of gear 1 22 is half the depth of the cleaning tank 11; the gear 1 22 is set to a longer length, so that when the cleaning basket 50 moves up and down, the gear 2 23 always remains in meshing with the gear 1 22, and the cleaning basket 50 can be adjusted to a suitable height. Then, the cleaning basket 50 is rotated, that is, the relative position of the cleaning basket 50 and the two ends of the tube body 41 is adjusted, and the steel parts at the same height in the cleaning basket 50 are washed, thereby improving the oxide scale shedding effect of the entire steel parts.

[0049] like Figure 1 、 Figure 3 As shown, a filter element 43 is provided at the position of the pipe body 41 in front of the water pump 42; the filter element 43 is provided to collect the shed oxide scale, reduce the amount of oxide scale distributed in the cleaning tank 11, and ensure that the oxide scale continues to fall off; at the same time, the setting for collecting the oxide scale avoids affecting the normal operation of the water pump 42.

[0050] The filter element 43 includes a liquid inlet pipe 431 and a liquid outlet pipe 432 that are relatively distributed in the upper and lower directions. The liquid inlet pipe 431 and the liquid outlet pipe 432 are connected by a connecting rod 433. Side plates 434 are provided on the outside of the liquid inlet pipe 431 and the liquid outlet pipe 432. A filter cavity is formed between the side plates 434, the liquid inlet pipe 431 and the liquid outlet pipe 432. Filter element 1 435 and filter element 2 436 are provided inside the filter cavity. The mesh on filter element 1 435 is larger than the mesh on filter element 2 436.

[0051] The detached oxide scale follows the cleaning liquid into the filter cavity through the liquid inlet pipe 431, and the detached oxide scale is intercepted by the filter element 1 435 and the filter element 2 436, and the cleaning liquid is discharged from the liquid outlet pipe 432. Figure 3 As shown by the arrow in , the operation of collecting the fallen oxide scale is completed.

[0052] In order to maintain the interception effect of the filter element 1 435 and the filter element 2 436, the filter element 1 435 and the filter element 2 436 are cleaned regularly. For this purpose, the filter element 1 435 and the filter element 2 436 are set to be detachable. Figure 3 As shown, the liquid inlet pipe 431 is provided with a flange 1 4311, the liquid outlet pipe 432 is provided with a flange 2 4321, and the connecting rod 433 is located between the flange 1 4311 and the flange 2 4321; the threaded section provided on the connecting rod 433 is threadedly engaged with two nuts 437, the filter element 1 435 is clamped and fixed by the upper nut 437 and the flange 1 4311, and the filter element 2 436 is clamped and fixed by the lower nut 437 and the flange 2 4321.

[0053] By rotating the nut 437 on the connecting rod 433 and adjusting the distance between the nut 437 and the flange 1 4311 and the flange 2 4321, the filter element 1 435 and the filter element 2 436 are disassembled and fixed. The operation is simple, and the oxide scale intercepted on the disassembled filter element 1 435 and the filter element 2 436 is cleaned.

[0054] like Figure 3 As shown, the upper end of the side plate 434 extends radially inward to form a cover plate 4341, and the cover plate 4341 is sealed with the flange 1 4311, and the lower end of the side plate 434 is sealed with the flange 2 4321 to avoid the problem of cleaning liquid leakage in the filter element 43. The flange 2 4321 of the side plate 434 is threadedly assembled by bolts 438; that is, the side plate 434 and the liquid inlet pipe 431 and the liquid outlet pipe 432 are detachably arranged. After the side plate 434 is removed from the liquid inlet pipe 431 and the liquid outlet pipe 432, the filter element 1 435 and the filter element 2 436 are disassembled and cleaned. After the cleaning is completed, the filter element 1 435 and the filter element 2 436 are assembled, and the side plate 434 is assembled to form a complete filter element 43.

[0055] A screw hole 4332 matching the bolt 438 is provided on the flange 1 4311. When the filter element 1 435 and the filter element 2 436 are taken out from the filter cavity, the bolt 438 is connected to the screw hole 4332 to fix the position of the side plate 434, thereby improving the convenience of operation.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
