[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] This embodiment provides a device for removing dirt from metal parts, such as Figure 1-Figure 3As shown, it includes a compacting mechanism 1, a wiping mechanism 2 and a guide member 3. The compacting mechanism 1 includes a compacting member 12 and a lifting cylinder 11, and the movable end of the lifting cylinder 11 is connected to the compacting member 12. The wiping mechanism 2 includes a wiping member 22 and a pushing cylinder 21, and the movable end of the pushing cylinder 21 is connected to the wiping member 22. The guide member 3 is provided with a vertical through hole 31 adapted to the compacting member 12 and a transverse through hole 32 adapted to the wiping member 22. The transverse through hole 32 is arranged crosswise with the vertical through hole 31. When the compacting member 12 is lifted along the vertical through hole 31 until its bottom end is located on the upper side of the transverse through hole 32, the wiping member 22 is pulled along the transverse through hole 32 to push the dirt at the bottom end of the compacting member 12 out of the guide member 3. The guide member 3 provides a smooth running channel for the compacting member 12 and the wiping member 22 , plays a guiding and positioning role in the running of the compacting member 12 and the wiping member 22 , so that the cleaning process of the compacting member 12 proceeds smoothly.

[0029] In this embodiment, the compacting member 12 of the compacting mechanism 1 is used to compact the permanent magnet. It is easy to absorb dust and metal particles during the compaction process. By setting the guide member 3 and the wiping mechanism 2, the lifting cylinder 11 drives the compacting member 12 to move upward along the vertical through hole 31 of the guide member 3. During the movement of the compacting member 12, the dust and metal particles absorbed around the compacting member 12 are blocked by the side wall of the vertical through hole 31 and are collected at the bottom end of the compacting member 12. When the compacting member 12 moves to the specified position, the pushing cylinder 21 drives the wiping mechanism 2 to move upward. The wiper 22 moves forward along the transverse through hole 32 of the guide member 3. When the wiper 22 reaches the lower end of the guide member 3, the upper surface of the wiper 22 is in contact with the bottom end of the guide member 3. The guide member 3 is stationary, and the wiper 22 continues to move forward. The powder adsorbed on the bottom end of the guide member 3 is scraped off by the wiper 22. After the wiper 22 is exposed from the guide member 3, the powder automatically falls out of the transverse through hole 32. Then, the guide member 3 and the wiper 22 are withdrawn from the guide member 3 to their initial positions, thereby completing the process of removing dirt from the compacting member 12. When the magnet is compacting, the lifting cylinder 11 drives the compacting member 12 to move downward and pass through the guide member 3, causing the bottom end of the compacting member 12 to undergo a compacting operation again. After the compaction process is completed, the above-mentioned dirt removal action is repeated.

[0030] The metal part decontamination device of this embodiment enables the compacting part 12 to be automatically cleaned by the back-and-forth movement of the wiping mechanism 2 during the process of being lifted after the compacting operation, without the need to stop the machine for manual wiping. The cleaning speed is fast and the efficiency is high. The cleaning process can be automatically completed online during the process of retracting the compacting part 12, which is convenient, fast and practical.

[0031] Preferably, the compacting member 12 is rod-shaped, and the wiping member 22 is flat. The width of the wiping member 22 is greater than the diameter of the compacting member 12, and the vertical through-hole 31 is disposed through the center of the transverse through-hole 32. The rod-shaped compacting member 12 reduces friction between it and the guide member 3, allowing it to move more smoothly along the vertical through-hole 31. The wiping member 22 can completely push dirt at the bottom of the compacting member 12 away from the compacting member 12, providing excellent wiping performance.

[0032] Preferably, a first fixing plate 5 is vertically provided on one side of the compacting mechanism 1. The first fixing plate 5 is connected to the fixed end of the lifting cylinder 11 and is used to fix the lifting cylinder 11. A second fixing plate 6 is laterally provided on the lower side of the wiping mechanism 2. The second fixing plate 6 is connected to the fixed end of the pushing cylinder 21 and is used to fix the pushing cylinder 21 to keep the lifting cylinder 11 and the pushing cylinder 21 running smoothly.

[0033] Preferably, the metal part decontamination device of this embodiment also includes an open waste receiving box 4. This box is positioned on the side of the guide member 3 away from the wiping mechanism 2, with its open end abutting the lower side of the transverse through hole 32. The waste receiving box 4 collects dirt pushed out of the transverse through hole 32 by the wiping member 22, preventing it from being scattered. It also recovers magnetic material adsorbed on the compacting member 12. A handle 41 is provided on the waste receiving box 4 for convenient handling.

[0034] Preferably, if Figure 1 and Figure 2 As shown, a notch 33 is provided on the side of the guide member 3 facing away from the wiping mechanism 2. The notch 33 extends downward from the middle of the transverse through hole 32 to the bottom end of the guide member 3. The waste receiving box 4 is placed against the notch 33. Figure 2 As shown, the notch 33 enables the dirt in the transverse through hole 32 to be completely pushed out by the wiping member 22, thereby preventing the dirt from being retained at the outlet of the transverse through hole 32, and the dirt falling from the transverse through hole 32 can be received by the waste receiving box 4.

[0035] Preferably, if Figure 5 and Figure 6As shown, the lifting cylinder 11 and the pushing cylinder 21 are both slide cylinders, which include a slide 112, an end plate 115, and a cylinder body 111. Two piston rods 113 are provided in the cylinder body 111, and the piston rods 113 are connected to the end plate 115. A linear guide 114 is provided on the cylinder body 111, and the slide 112 is slidably provided on the linear guide 114. The slide 112 is also connected to the end plate 115. The extension and retraction of the piston rod 113 can drive the end plate 115 to move and drive the slide 112 to slide along the linear guide 114. The slide 112 is provided with a slide groove 116 that is compatible with the linear guide. The extension and retraction movement of the piston rod 113 in the cylinder body 111 can drive the end plate 115 and the slide 112 to move synchronously. The compacting member 12 is connected to the end plate 115 of the lifting cylinder 11 through the first connecting plate 13 , and the wiping member 22 is connected to the slide 112 of the pushing cylinder 21 .

[0036] In this embodiment, both the lift cylinder 11 and the push cylinder 21 utilize HLQ16*30SA dual-axis precision slide cylinders. The piston rod 113 of the lift cylinder 11 retracts and extends, driving the end plate 115 to move, thereby driving the compacting member 12. The piston rod 113 of the push cylinder 21 retracts and extends, driving the slide 112 along the linear guide 114, thereby driving the wiping member 22. This ensures smooth operation, accurate positioning, and excellent stability of the compacting member 12 and the wiping member 22.

[0037] Preferably, the wiping member 22 includes a push-pull plate 222 and a second connecting plate 221, the width of the push-pull plate 222 is smaller than the width of the second connecting plate 221, the length of the push-pull plate 222 is greater than the length of the second connecting plate 221, the second connecting plate 221 is connected to the pushing cylinder 21, and the push-pull plate 222 extends into the transverse through hole 32.

[0038] Preferably, if Figure 6 As shown, an arcuate notch 223 is provided at one end of the push-pull plate 222 away from the second connecting plate 221. The width of the arcuate notch 223 is greater than or equal to the diameter of the compacting member 12. As the push-pull plate 222 is pushed through the transverse through-hole 32, dirt collected at the bottom end of the guide member 3 is scraped off by the push-pull plate 222 and collected in the arcuate notch 223. The dirt is then pushed out of the transverse through-hole 32 along with the push-pull plate 222. The arcuate notch 223 accommodates the scraped dirt during the pushing process of the push-pull plate 222, allowing the push-pull plate 222 to completely push the dirt out of the guide member 3, thus preventing the scraped dirt from being scattered during the pushing process.

[0039] Preferably, the wiper 22 is a polyetheretherketone (PEEK) sheet, which effectively wipes the compacting member 12 and offers excellent wear resistance, effectively scraping away dust and metal particles adsorbed on the compacting member 12. The guide member 3 is non-magnetic and does not attract dust and metal particles. The guide member 3 is constructed of 316 stainless steel, which is rust-resistant and wear-resistant. The compacting member 12 is made of SKD11 die steel (HRC58-60), which offers excellent wear resistance and compressive strength.

[0040] The compacting mechanism 1 and the wiping mechanism 2 of this embodiment are both connected to the control system. The frequency of the activity of the pushing cylinder 21 of the wiping mechanism 2 can be set according to the usage status of the compacting part 12 during the compaction process to adjust the cleaning frequency of the compacting part 12 so that the compacting part 12 meets the requirements of magnet production.

[0041] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
