Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to an automatic graphite cleaning device for railway cast steel wheels. Background Technology

[0002] In the production of cast steel wheels, the graphite mold (graphite housing) is a key mold that needs to be cleaned after each demolding to remove residual metal oxides, release agents, and impurities such as grit from the surface. Currently, the cleaning of graphite molds mainly relies on manual operation, resulting in high labor costs and high labor intensity. Furthermore, manual cleaning is inefficient, severely impacting production efficiency. During manual cleaning, uneven wiping pressure makes it difficult to precisely control the cleaning pressure, easily leading to incomplete cleaning in certain areas or over-cleaning, causing structural damage and significantly shortening the service life.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1 to 4 As shown, the automatic graphite cleaning device for railway cast steel wheels of this utility model includes a power shaft 1, a connecting assembly 2, a floating adjustment assembly 3, a brush head 4, and an anti-detachment assembly 5. One end of the floating adjustment assembly 3 is connected to the power shaft 1 through the connecting assembly 2, which provides rotational power to the floating adjustment assembly 3. The brush head 4 is movably mounted on the floating adjustment assembly 3 to control the downward pressure of the brush head 4. The anti-detachment assembly 5 passes through the brush head 4 and is fixed to the floating adjustment assembly 3 to secure the brush head 4.

[0028] The floating adjustment assembly 3 includes an adapter 31, a limiting rod 32, a compression spring 33, and an adjusting nut 34. The limiting rod 32 is located at the lower end of the adapter 31, and the compression spring 33 is sleeved on the limiting rod 32 to provide up and down floating pressure. The adjusting nut 34 is located on the limiting rod 32 and abuts against the compression spring 33 to adjust the pressure of the compression spring 33.

[0029] Furthermore, in the automatic graphite cleaning device for railway cast steel wheels of this utility model, a connecting groove 311 is provided in the middle of the upper end of the adapter 31, a first keyway 312 is provided on one side of the connecting groove 311, and a first pin hole 313 is provided through the adapter 31 in the circumferential direction.

[0030] Furthermore, in the automatic graphite cleaning device for railway cast steel wheels of this utility model, the connecting component 2 includes a pin 21 and a key 22. The bottom of the power shaft 1 is provided with a second keyway 11, and the circumferential direction of the power shaft 1 is provided with a second pin hole 12. The power shaft 1 is inserted into the connecting groove 311. The first keyway 312 and the second keyway 11 are connected by the key 22. The pin 21 passes through a first pin hole 313 and is connected to the second pin hole 12, thereby ensuring the torque transmission of the power shaft 1. At the same time, when used in multiple directions, the adapter 31 will not detach from the power shaft 1, thus improving safety.

[0031] Furthermore, in the automatic graphite cleaning device for railway cast steel wheels of this utility model, the limiting rod 32 adopts a polygonal column structure, the upper end of the limiting rod 32 is provided with a threaded platform 321, and the bottom of the limiting rod 32 is provided with a threaded hole 322.

[0032] Furthermore, in the automatic graphite cleaning device for railway cast steel wheels of this utility model, the adjusting nut 34 engages with the threaded platform 321, and the brush head 4 is provided with a sliding groove 41 in the middle. The sliding groove 41 matches the limiting rod 32. The brush head 4 is slidably mounted on the limiting rod 32 through the sliding groove 41. One end of the compression spring 33 abuts against the adjusting nut 34, and the other end of the compression spring 33 abuts against the brush head 4. The free rotation of the brush head 4 is restricted by the limiting rod 32, ensuring that the brush head 4 rotates when the limiting rod 32 rotates. At the same time, the adjusting nut 34 adjusts the pressure of the compression spring 33, thereby ensuring the pressure required for cleaning. When the downward pressure of the brush head 4 is too large, the brush head 4 can compress and adjust the compression spring 33 according to the downward pressure. When the downward pressure of the brush head 4 is too small, the compression spring 33 can provide downward pressure to the brush head 4, thereby achieving precise control of the cleaning pressure.

[0033] Furthermore, in the automatic graphite cleaning device for railway cast steel wheels of this utility model, the anti-detachment component 5 includes an anti-detachment screw 51 and a washer 52. The anti-detachment screw 51 is matched with the threaded hole 322. The top diameter of the anti-detachment screw 51 is larger than the maximum diameter of the sliding groove 41. The anti-detachment screw 51 passes through the washer 52 and the sliding groove 41 in sequence and engages with the threaded hole 322, thereby effectively preventing the brush head 4 from detaching from the floating adjustment component 3 and improving safety.

[0034] Specifically, during use, the adapter 31 is connected to the power shaft 1 via the connecting component 2, so that the power shaft 1 provides rotational power to the limiting rod 32 through the adapter 31 and presses down the limiting rod 32. At this time, the brush head 4 continues to apply downward pressure after it comes into contact with the mold to be cleaned. The brush head 4 slides upward along the limiting rod 32 through the sliding groove 41, which compresses the compression spring 33. In order to prevent the limiting rod 32 from going beyond the brush head 4 after the compression spring 33 is compressed, or to prevent the compression spring 33 from being compressed after the brush head 4 moves upward, the compression amount of the compression spring 33 can be adjusted by adjusting the adjusting nut 34 to ensure that the compression spring 33 provides downward pressure to the brush head 4. When encountering an uneven surface of the mold to be cleaned, the compression spring 33 rebounds in the case of depression, driving the brush head 4 to press down, so that the brush head 4 always comes into contact with the mold surface. In the case of protrusion, the compression spring 33 is further compressed, so that the downward pressure of the brush head 4 always remains within a safe cleaning range, thereby ensuring that the brush head 4 has a good cleaning effect on the mold surface, while avoiding excessive pressure from the brush head 4 on the uneven surface, which could cause damage to the mold.

[0035] In summary, compared with the prior art, the automatic graphite cleaning device for railway cast steel wheels of this utility model has the following advantages and beneficial effects:

[0036] The rotational power provided by the drive shaft effectively reduces labor costs and labor intensity, and improves cleaning efficiency. The floating adjustment component, in conjunction with the brush head, can adjust the cleaning pressure when the brush head presses down, thereby effectively avoiding the problems of excessive pressure causing over-cleaning and insufficient pressure causing incomplete cleaning. This effectively ensures the cleaning pressure and improves the service life of the mold.
