In this process, part of the oil on the placement box due to tension and liquid viscosity will fall due to inertia and its own gravity when moving. At the same time, the contact area of the sliding plate with the bottom of the placement box is larger, so the friction is greater, and the contact area of the sliding plate through the sliding block in the movable groove is smaller, and the friction is smaller. Compared with the two and under the action of inertia, the movable plate drives the sliding block to move a longer stroke, and then periodically squeezes the compression spring, causing the movable plate to shake more frequently, thereby facilitating the dripping of residual oil.

When the movable plate is squeezed and moves, the movable plate can shake, thereby making the movable plate move frequently, thereby accelerating the movement of the oil in the placing box and at the same time making the movable plate drive the anti-slip rod to move. Since the anti-slip rod is covered with a powder metallurgy product, the powder metallurgy product in the placing device is moved while the oil moves, thereby accelerating the oil immersion efficiency during oiling.
[0014] 4. The present invention arranges a placement device to place powder metallurgy products.

[0015] 5. The present invention sets a screening device and a placing device to cooperate with the cylinder to perform periodic telescopic movement. At this time, the placing device will move following the sliding of the sliding plate. In this process, part of the oil on the placing box due to tension and liquid viscosity will fall due to inertia and its own gravity when moving. At the same time, the contact area of the sliding plate with the bottom of the placing box is larger, so the friction is greater, and the contact area of the sliding plate through the sliding block in the movable groove is smaller, and the friction is smaller. Compared with the two and under the action of inertia, the movable plate drives the sliding block to move a longer stroke, and then periodically squeezes the compression spring, so that the movable plate produces more frequent shaking, which facilitates the dripping of residual oil, and thus makes the residual oil on the placing device less.

Since the connecting plate 623 is connected to the sliding plate 626, the output end of the cylinder 61 is fixed to the connecting plate 623, so that when the cylinder 61 is started, the sliding plate 626 can be pushed to slide on the trapezoidal support block 624. Since the cylinder 61 will perform periodic telescopic motion, the placement device 7 at this time will move following the sliding of the sliding plate 626, and then the oil on the surface of the placement device 7 will be screened.

The spiral blades 662 on the two rotating rods 661 on the extension rod 65 are symmetrically arranged. When the oil passes between the spiral blades 662, the rotation of the spiral blades 662 will disturb the oil, making the oil flow more evenly and improving the oil passing effect.
[0023] Example 2: Please refer to Figure 1 - Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the placing device 7 includes a placing box 71, the inner wall of the placing box 71 is slidably connected with a movable plate 73 through a slide groove 72, and the slide groove 72 is opened in the wall of the placing box 71, the outer wall of the bottom of the movable plate 73 is fixedly connected with a shaking device 76, and the side of the movable plate 73 away from the shaking device 76 is fixedly connected with an anti-drop rod 79, the inner wall of the bottom of the placing box 71 is slidably connected with the outer wall of the push plate 67 through a square groove 75, the inner wall of the bottom of the placing box 71 is opened with a movable groove 78, the inner wall of the bottom of the placing box 71 is opened with an oil hole 74, and the oil hole 74 is connected to the movable plate 73. The grooves 78 are interconnected, a side through groove 77 is provided on the inner wall at the bottom of the placement box 71, and the side through groove 77 is connected to the movable groove 78. The side wall of the placement box 71 of the placement device 7 has holes to facilitate the passage of oil, and an anti-slip rod 79 is provided on the movable plate 73 sliding in the placement box 71. Since most powder metallurgy products are annular parts with a hole in the middle, after the powder metallurgy products are inserted, the limit cover 3 on the top can prevent the oil from pushing the powder metallurgy products into the fixed box 41, and a square groove 75 is provided at the bottom of the fixed box 41, so that the interior of the placement box 71 entering the fixed box 41 can be immediately immersed in oil.
[0024] The outer wall of the placement box 71 is slidably connected to the outer wall of the limiting cover 3 , the outer wall of the bottom of the placement box 71 contacts the outer wall of the top of the fixing strip 44 , and the outer wall of the movable plate 73 contacts the outer wall of the push plate 67 .
[0025] The shaking device 76 includes a sliding block 761, the outer wall of the sliding block 761 is symmetrically fixedly connected to the oil compression spring 762, the outer wall of the top of the sliding block 761 is fixedly connected to the outer wall of the bottom of the movable plate 73, the side wall of the sliding block 761 is slidably connected to the inner wall of the placement box 71 through the movable groove 78, and the end of the compression spring 762 away from the sliding block 761 is fixedly connected to the inner wall of the placement box 71, and the sliding block 761 is set to slide in the movable groove 78. At the same time, the compression spring 762 connects the sliding block 761 and the inner wall of the placement box 71. When the movable plate 73 is squeezed and moves, the movable plate 73 can be shaken, thereby making the movable plate 73 move more frequently. The movable plate 73 then drives the sliding block 761 to move a longer distance, thereby periodically squeezing the compression spring 762, causing the movable plate 73 to vibrate more frequently, thereby facilitating the dripping of the residual oil. The movable plate 73 will slide in the placement box 71 during the process of the placement box 71 following the movement of the sliding plate 626. At this time, the sliding block 761 will discharge the oil in the movable groove 78 through the side groove 77 and the oil hole 74 during the movement, thereby reducing the residual oil on the placement device 7.
[0026] Working principle: When in use, the frame 1 provides a stable supporting foundation for the entire equipment, and the hydraulic cylinder 2 is fixed on the frame 1. Its output port is connected to the limit cover 3, which can then control the lifting and lowering of the limit cover 3. When in use, the powder metallurgy product to be processed is placed in the placement device 7. At this time, the placement device 7 on the placement plate 5 is pushed toward the limit cover 3. After sliding into the limit cover 3 through the guidance of the frame 1, the hydraulic cylinder 2 is started to carry the placement device 7 into the oil storage tank 4. The fixed box 41 of the oil storage tank 4 stores the oil for oiling, thereby completing the oiling treatment of the powder metallurgy product.
[0027] In order to speed up the oil passing efficiency, a screening device 6 is provided to screen the oil, and components inside the fixed box 41 are provided to assist the screening process, wherein the fixed box 41 in the oil storage tank 4 is slidably connected with the push rod 63 of the screening device 6 through the through hole 42, so that the screening force can be transmitted to the inside of the fixed box 41, the triangular support frame 43 and the fixed bar 44 in the fixed box 41 play the role of supporting the placement device 7, and allow the oil to flow in the fixed box 41 through the oil permeable groove 45 and the connecting groove 47, and the arc support plate 46 provides sliding support for the slider 64 of the screening device 6; When the cylinder 61 of the screening device 6 is started, the cylinder 61 will push the push rod 63 to move, and the push rod 63 will drive the slider 64 to slide on the arc-shaped support plate 46, and the extension rod 65 on the slider 64 is connected to the pushing device 66. During the movement of the slider 64, the synchronously moving extension rod 65 will drive the rotating rod 661 to move. Since the top of the rotating rod 661 is restricted by the upper limit notch 666 of the fixed plate 664, and the fixed plate 664 is fixed in the fixed box 41, the rotating rod 661 moves stably along the fixed plate 664. Because the fixed gear 663 on the rotating rod 661 is engaged with the tooth groove 665 of the fixed plate 664, the rotating rod 661 is driven by the fixed gear 663 to rotate while moving, and the two gears on the extension rod 65 are driven by the fixed gear 663 to rotate. The spiral blades 662 on the rotating rod 661 are symmetrically arranged. When the oil passes between the spiral blades 662, the rotating action of the spiral blades 662 will disturb the oil, making the oil flow more evenly and improving the oiling effect. This is because when the spiral blades 662 on the two rotating rods 661 are symmetrically arranged and rotate synchronously in opposite directions, the oil will form a stable flow channel between the two, thereby enhancing the fluidity and circulation of the oil. The symmetrical spiral blades 662 will ensure that the oil is evenly driven in all directions, thereby avoiding local oil accumulation and poor flow, further ensuring the uniform effect of the oiling operation, allowing the powder metallurgical products to fully contact the oil, ensuring a more ideal effect of the oiling treatment, increasing the fluidity of the oil while preventing the oil from settling. When the slider 64 in the screening device 6 moves, the push plate 67 inserted into the square groove 75 of the placement box 71 will push the movable plate 73 of the placement device 7 to move. Since the movable plate 73 in the placement box 71 can slide in the placement box 71 through the slide groove 72, and in the shaking device 76 at the bottom of the movable plate 73, a sliding block 761 is set to slide in the movable groove 78, and at the same time, the compression spring 762 connects the sliding block 761 and the inner wall of the placement box 71. When the movable plate 73 is squeezed and moves, the movable plate 73 can be shaken, thereby making the movable plate 73 move frequently. The movement of the oil in the placement box 71 is accelerated. The anti-slip rod 79 on the movable plate 73 prevents the powder metallurgical product from escaping from the placement box 71. The oil holes 74, the movable grooves 78 and the side grooves 77 at the bottom of the placement box 71 allow the oil to flow. The push plate 67 cooperates with the movable plate 73 on the placement box 71 after passing through the square groove 75 to push the movable plate 73 to move, thereby causing the movable plate 73 to drive the anti-slip rod 79 to move. Since the powder metallurgical product is sleeved on the anti-slip rod 79, the powder metallurgical product in the placement device 7 is moved while the oil moves, thereby accelerating the oil immersion efficiency during oiling. The side wall of the placement box 71 of the placement device 7 has holes to facilitate the passage of oil. An anti-drop rod 79 is provided on the movable plate 73 sliding in the placement box 71. Since most powder metallurgy products are ring-shaped parts with holes in the middle, after the powder metallurgy products are inserted, the limit cover 3 on the top can prevent the oil from pushing the powder metallurgy products into the fixed box 41. A square groove 75 is provided at the bottom of the fixed box 41, so that the inside of the placement box 71 entering the fixed box 41 can be immediately immersed in the oil, reducing the time required for the oil to pass through the placement box 71. After the oiling operation is completed, the placement device 7 containing the powder metallurgy product is taken out from the oil storage tank 4 and placed on the sliding plate 626 of the screening device 62. The limit frame 621 in the screening device 62 fixes the cylinder 61 and the limit plate 622, and the trapezoidal support block 624 on the limit plate 622 supports the sliding plate 626, so that it can slide along the trapezoidal support block 624 within the limit range of the limit frame 621 and the connecting ring 625. Since the connecting plate 623 is connected to the sliding plate 626, the output end of the cylinder 61 is fixed to the connecting plate 623, so that when the cylinder 61 is started, the sliding plate 626 can be pushed to slide on the trapezoidal support block 624. Since the cylinder 61 will perform periodic telescopic motion, the placement device 7 at this time will move with the sliding of the sliding plate 626. In this process, part of the oil on the placement box 71 due to tension and liquid viscosity falls due to the action of inertia and its own gravity when moving; At the same time, since the contact area between the bottom box 71 and the sliding plate 626 is larger, the friction force is greater, and the contact area between the sliding plate 626 and the sliding block 761 in the movable groove 78 is smaller, the friction force is smaller. Compared with the two and under the action of inertia, the movable plate 73 drives the sliding block 761 to move a longer stroke, thereby periodically squeezing the compression spring 762, so that the movable plate 73 produces more frequent shaking, thereby facilitating the dripping of residual oil. The movable plate 73 will slide in the placement box 71 during the process of the placement box 71 following the movement of the sliding plate 626. At this time, the sliding sliding block 761 will discharge the oil in the movable groove 78 through the side groove 77 and the oil hole 74 during the movement, thereby making the residual oil on the placement device 7 less. After the oil is discharged, it flows to the sliding plate 626 and discharges the flowing oil through the oil leakage groove 627 of the sliding plate 626. Placing an oil barrel under the oil leakage groove 627 can also recycle the oil after oiling.
