Description

Technical Field

[0001] This utility model relates to the field of metallurgical cleaning technology, specifically to a cleaning device for powder metallurgy products. Background Technology

[0002] During the production process, powder metallurgy products are often coated with pressing lubricants, release agents, sintering residues, or other contaminants from the processing. To ensure the final performance and appearance quality of the products, cleaning is an essential and critical process. Currently, common powder metallurgy product cleaning equipment mainly adopts immersion, spraying, or a combination of both methods. This type of equipment is usually equipped with a cleaning chamber and a spraying system (including pumps, pipelines, and nozzles), which sprays cleaning agents onto the metallurgical products through the nozzles to perform the cleaning operation.

[0003] However, this cleaning method has certain shortcomings. Its cleaning efficiency is affected by the removal and placement of products. Specifically, after a batch of products is cleaned, the equipment needs to be stopped, the cleaning chamber door opened, and then the operator needs to manually remove the cleaned products one by one from the support structure (such as a turntable or clamp) inside the cleaning chamber. Then, the next batch of products to be cleaned is clamped or placed onto the support structure inside the cleaning chamber. This series of operations results in a long waiting time during the removal and placement of products, which affects the cleaning efficiency. Therefore, a device is needed to solve the above problems. Utility Model Content

A drainage groove is provided on one side of the housing. The drainage groove is located at the bottom of the cleaning chamber and is connected to the cleaning chamber to discharge sewage.

[0006] Optionally, the replacement mechanism includes a top plate, a connecting column, and a bottom plate. The top of the housing has a communication port that communicates with the cleaning chamber. The top plate is detachably mounted on the inner wall of the communication port. The connecting column is rotatably connected to the lower surface of the top plate, and the bottom plate is fixedly connected to the lower surface of the connecting column.

[0007] Optionally, a holding basket can be detachably connected to the outer surface of the connecting column. The holding basket is used to hold the products to be cleaned.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a cleaning device for powder metallurgy products, including a shell 1 with a cleaning chamber 2 inside, multiple nozzles 3 inside the cleaning chamber 2, a water supply pipe 4 fixedly connected to one side of the shell 1 for supplying cleaning liquid to the nozzles 3, a drive motor 5 fixedly connected inside the shell 1 and the output end of the drive motor 5 penetrating into the interior of the cleaning chamber 2, and a rotating disk 6 fixedly connected to the output end of the drive motor 5 through a keyway.

[0018] The upper surface of the rotating disk 6 is detachably connected to a replacement mechanism for holding the products to be cleaned. The outer surface of the upper surface of the rotating disk 6 is also provided with a fixing mechanism to fix the position of the replacement mechanism. A drainage groove 7 is provided on one side of the housing 1. The drainage groove 7 is located at the bottom of the cleaning chamber 2 and is connected to the cleaning chamber 2 to discharge sewage.

[0019] The product to be cleaned is placed in the replacement mechanism. After the replacement mechanism is placed in the cleaning chamber 2, the fixing mechanism can fix the replacement mechanism, thereby fixing the replacement mechanism together with the rotating disk 6. During the process of the drive motor 5 driving the rotating disk 6 to rotate, the replacement mechanism can be driven to rotate through the rotating disk 6. The water supply pipe 4 introduces external cleaning agent into the nozzle 3, and then sprays it into the cleaning chamber 2 from the nozzle 3 to clean the product placed in the replacement mechanism. The wastewater generated during cleaning will be discharged from the bottom drain trough 7 to the outside of the housing 1. The drain trough 7 can be connected to the wastewater treatment pipe to reduce the pollution of the cleaning environment. The output shaft of the drive motor 5 is connected to the housing 1 through a sealed bearing to prevent leakage in the gap. This method is a well-known technology in the prior art and will not be described in detail here. At the same time, heat dissipation holes are opened on the housing 1 to dissipate heat from the drive motor 5.

[0020] In this embodiment, as a preferred solution, the replacement mechanism includes a top plate 8, a connecting column 9, and a bottom plate 10. The top of the housing 1 has a communication port 11 that communicates with the cleaning chamber 2. The top plate 8 is detachably mounted on the inner wall of the communication port 11. The connecting column 9 is rotatably connected to the lower surface of the top plate 8, and the bottom plate 10 is fixedly connected to the lower surface of the connecting column 9. A holding basket 12 is detachably connected to the outer surface of the connecting column 9. The holding basket 12 is used to hold the products to be cleaned. The holding basket 12 is semi-circular and has a notch groove on one side that matches the outer diameter of the connecting column 9. Multiple partitions 13 are detachably connected inside the holding basket 12 to separate the products to be cleaned. Both the partitions 13 and the holding basket 12 are rigid mesh structures.

[0021] The replacement mechanism can be inserted into the cleaning chamber 2 through the connecting port 11 at the top of the housing 1. The two holding baskets 12 are provided with through holes on both sides, and two holding baskets 12 can be joined together with bolts. The notch in the middle of the holding basket 12 is adapted to the size of the connecting column 9. After the two holding baskets 12 are joined together, the notch can squeeze the middle connecting column 9 tightly. During the process of the drive motor 5 driving the base plate 10 and the connecting column 9 to rotate, the connecting column 9 can drive the outer holding basket 12 to rotate together. After the metal products to be cleaned are placed in the holding basket 12, the partition 13 can be used to separate the metal products, reduce the cleaning dead corners caused by the stacking of metal products during the cleaning process, and make the cleaning process more thorough.

[0022] In this embodiment, as a preferred option, the fixing mechanism includes a pressure strip 14 and a clamping strip 15. The pressure strip 14 is rotatably connected to the upper surface of the rotating disk 6 via a torsion spring. The clamping strip 15 is fixedly connected to one end of the pressure strip 14 to clamp the bottom plate 10. Friction pads 16 are fixedly connected to one side of the clamping strip 15 and the outer surface of the connecting column 9 to increase the friction force.

[0023] After the replacement mechanism is placed into the cleaning chamber 2, the base plate 10 can press against the pressure strip 14, causing the pressure strip 14 to rotate around a pivot on one side. During the process of pressing down on the pressure strip 14 and causing it to rotate, the clamping strip 15 connected to one side of the pressure strip 14 will rotate synchronously, allowing the clamping strip 15 to adhere to one side of the base plate 10, thus supporting the base plate 10 and connecting it to the rotating disk 6. After cleaning is complete, pulling the top plate 8 upwards causes the base plate 10 to move upwards as well. At this time, the base plate 10 separates from the pressure strip 14, and the torsion spring at the pivot of the pressure strip 14 causes the pressure strip 14 to lift, causing the clamping strip 15 to... 5. Move together and separate from the base plate 10, thereby lifting the replacement mechanism for replacement. After the new replacement mechanism is placed, it will press down on the pressure strip 14 again, causing the pressure strip 14 to drive the clamping strip 15 to rotate. The position of the base plate 10 is fixed by the clamping strip 15. There can be multiple fixing mechanisms, which are distributed in a ring on the upper surface of the rotating disk 6. The outer surfaces of the clamping strip 15 and the connecting column 9 are provided with friction pads 16. The friction pads 16 on the clamping strip 15 can increase the friction between it and the base plate 10. The friction pads 16 on the outer side of the connecting column 9 can increase the friction between the connecting column 9 and the holding basket 12 to reduce relative movement.

[0024] In this embodiment, as a preferred option, multiple sealing gaskets 17 are fixedly connected to the outer circular surface of the top plate 8. The sealing gaskets 17 are used to seal the gap between the top plate 8 and the housing 1. A lever 18 is rotatably connected to the upper surface of the housing 1. The lever 18 can fit against the upper surface of the top plate 8 to prevent the top plate 8 from moving upward.

[0025] After the replacement mechanism is placed in the cleaning chamber 2, the top plate 8 of the replacement mechanism will be flush with the top of the housing 1. The outer sealing gasket 17 can fill the gap between the housing 1 and the top plate 8 to prevent the cleaning agent from leaking out of the gap. After rotating the lever 18 so that the lever 18 is above the top plate 8, the lever 18 can prevent the top plate 8 from moving upward, thereby fixing the position of the top plate 8 and the bottom plate 10. The top plate 8 can only be taken out after the lever 18 is moved aside.

[0026] In this invention, the working steps of the device are as follows: 1. Place the metal products to be cleaned in the holding basket 12 and use the partition 13 to separate them appropriately to reduce the stacking and obstruction between the metal products. After placement, install the two holding baskets 12 on the outside of the connecting column 9 and fix them with bolts. 2. Place the replacement mechanism into the cleaning chamber 2, ensuring that the base is aligned with the axis of the rotating disk 6. After placement, rotate the lever 18 to the top of the top plate 8 to limit the position of the top plate 8. Then, introduce the cleaning agent into the water pipe 4 to clean the metal products. 3. While cleaning, prepare the replacement mechanism for the next use. After the current replacement mechanism is cleaned, open the switch 18 to remove the replacement mechanism. Then put the replacement mechanism to be cleaned into it and continue cleaning. Afterwards, disassemble the replacement mechanism that was just taken out, take out the cleaned metal products inside, and put the metal products to be cleaned into the replacement mechanism to prepare for the next wave of cleaning. Repeat this cleaning cycle.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
