[0001] The utility model belongs to the technical field of powder metallurgy workpiece processing, and in particular relates to an oil passing device for powder metallurgy workpieces. Background Art

[0002] The oiling device for powder metallurgy workpieces is usually used to form a protective oil film on the surface of the workpiece to prevent oxidation and corrosion. This device usually includes an oil tank and related conveying system to immerse the workpiece in oil or apply an oil film on the surface of the workpiece. This helps to improve the corrosion resistance and surface quality of the workpiece.

[0003] At present, the prior art oiling device for powder metallurgy workpieces has the following disadvantages during use:

[0004] On the one hand, batches of powder metallurgy workpieces are scattered and placed in an oil tank for oiling, which causes the workpieces to be scattered in the oil tank. Later, they need to be salvaged manually with handheld salvage tools, which has high labor intensity and lacks a structure that can salvage batches of powder metallurgy workpieces, thereby greatly reducing the efficiency of oiling;

[0005] Secondly, the salvaged powder metallurgy workpieces need to be unloaded manually, and there is a lack of a structure that can automatically unload the salvaged workpieces. The manual unloading efficiency is low and the use effect is poor. For this reason, we propose an oiling device for powder metallurgy workpieces. Utility Model Content

[0008] A one-up and one-down transmission assembly is installed on the inner side of the oil tank and connected to one side wall of the two brackets facing each other. The one-up and one-down transmission assembly is used to realize left-up and right-down or left-down and right-up actions for the two brackets;

[0009] The push-out assembly is installed on the bracket and connected to the top of the oil tank. The push-out assembly is used to push the powder metallurgy workpiece that has been oiled on the filter screen b onto the filter screen a.

[0010] Among them, the opening a is set so that the pushing component can push the workpiece placed on the top of the filter screen b onto the filter screen a. The filter screen a can filter the oil and water remaining when the workpiece falls, and enables the remaining part of the oil and water to flow back into the oil tank for recycling.

[0011] As a preferred embodiment, the one-up-and-one-down transmission component includes an n-shaped rod fixedly connected to the middle of the inner bottom wall of the oil tank.

[0015] As a preferred embodiment, a toothed plate is fixedly connected to the top end of one of the vertical rods. A gear is meshed above the toothed plate. The gear is fixedly connected to the outside of the output shaft of the motor b. The motor b is fixed to the top edge of the oil tank through a support seat.

[0016] Compared with the prior art, an oil-passing device for powder metallurgy workpieces provided by the present utility model has at least the following beneficial effects:

[0017] (1) By setting the one-up-and-one-down transmission component, after starting the motor a, the transmission rod can be rotated forward and backward, and with the cooperation of multiple components, the two brackets can realize the actions of rising on the left and descending on the right or descending on the left and rising on the right in the oil tank.

When the powder metallurgy workpiece placed on one side of the filter screen b is immersed in oil, the powder metallurgy workpiece placed on the other side of the filter screen b and immersed in oil can be fished up, which can greatly improve the oil immersion efficiency and has good use effect;

[0018] (2) Through the setting of the pushing component, when the powder metallurgical workpiece placed on the filter screen b on one side of the bracket is pulled up, and the toothed plate on the corresponding side is meshed with the gear, and then the gear is driven to rotate by the motor b set on this side, so that the toothed plate can drive the push plate and the baffle connected by the two connecting rods to move toward the opening a, so that the setting of the push plate and the baffle can push the powder metallurgical workpiece on the filter screen b onto the filter screen a, and under the setting of the filter screen a, the residual oil dripping on the surface of the powder metallurgical workpiece can be filtered and recovered into the oil tank. According to the above, it can be seen that the pushing component can automatically push out and unload the powder metallurgical workpiece that has been oiled on the filter screen b, thereby greatly improving the efficiency of unloading, without the need for manual salvage and unloading, and the use effect is good.

[0028] Example

[0029] On the one hand, batches of powder metallurgy workpieces are scattered and placed in an oil tank for oiling, which causes the workpieces to be scattered in the oil tank. Later, they need to be salvaged manually with handheld salvage tools, which has high labor intensity and lacks a structure that can salvage batches of powder metallurgy workpieces, thereby greatly reducing the efficiency of oiling;

[0030] Secondly, the salvaged powder metallurgy workpieces need to be unloaded manually, and there is a lack of a structure that can automatically unload the salvaged workpieces. The manual unloading efficiency is low and the use effect is poor.

[0031] To do this, see Figures 1-5 The utility model provides an oil-passing device for powder metallurgy workpieces, comprising: an oil-passing box 1 with an opening on the top, openings a2 are provided on both side walls of the oil-passing box 1, and filters a3 are fixed to the oblique grooves on the top of the oil-passing box 1 on the two opposite sides of the two openings a2, and brackets 5 with U-shaped cross-sections are slidably attached to the inner walls of both sides of the oil-passing box 1, and filters b51 are fixed to the inner walls of the brackets 5, and the bottom ends of the filters b51 are flush with the bottom ends of the brackets 5;

[0032] A one-up and one-down transmission assembly 4 is installed on the inner side of the oil tank 1 and connected to one side wall of the two brackets 5 facing each other. The one-up and one-down transmission assembly 4 is used to realize the left-up and right-down or left-down and right-up actions of the two brackets 5;

[0033] A pushing component 6 is installed on the bracket 5 and is connected to the top of the oil passing tank 1. The pushing component 6 is used to push the powder metallurgy workpiece that has passed through the oil on the filter screen b51 onto the filter screen a3.

[0034] Among them, the opening a2 is provided to facilitate the pushing component 6 to push the workpiece placed on the top of the filter screen b51 onto the filter screen a3. The filter screen a3 can filter the residual oil and water when the workpiece falls, and enables the residual part of the oil and water to flow back into the oil passing tank 1 for recycling.

[0035] This solution has the following working process: As shown in the appendix Figure 1 First, the powder metallurgy workpiece that has been filtered on the filter screen b51 in the raised state on the left side can be pushed out for discharging. The powder metallurgy workpiece on the filter screen b51 is pushed onto the filter screen a3 through the pushing component 6 to achieve the purpose of convenient discharging. After discharging, the pushing component 6 is reset, and a new batch of powder metallurgy workpieces are placed on the filter screen b51 at this place and wait for oil immersion. Thereafter, through a one-rising-and-one-falling transmission component 4, the two brackets 5 are made to move left-down and right-up. Then, the powder metallurgy workpiece on the top of the filter screen of the right-side bracket 5 can be fished out from the oil in the oil passing tank 1, and at this time, the powder metallurgy workpiece on the top of the filter screen of the left-side bracket 5 can be immersed in the oil for oil passing, thereby further improving the oil passing efficiency and having a good use effect.

[0036] According to the above working process, it can be seen that: through the provided one-rising-and-one-falling transmission component 4, the two brackets 5 can perform left-rising and right-falling or left-falling and right-rising actions in the oil passing tank 1, so that the powder metallurgy workpieces placed on the filter screens b51 of the two brackets 5 can be switched to immerse in the oil in the oil passing tank 1. When the powder metallurgy workpiece placed on one side of the filter screen b51 is being oil-immersed, the powder metallurgy workpiece that has been oil-immersed and placed on the other side of the filter screen b51 can be fished out, thereby greatly improving the oil immersion efficiency and having a good use effect. Secondly, by setting the pushing component 6, the powder metallurgy workpiece that has passed through the oil on one side of the filter screen b51 can be automatically pushed out for discharging, thus greatly improving the discharging efficiency and eliminating the need for manual fishing and discharging, and having a good use effect.

[0037] Furthermore, as shown in Figure 2 and Figure 3As shown, it is worth specifically explaining that in order to enable the automatic switching of the powder metallurgy workpieces on the two filter screens b51 for oil immersion, a lifting and lowering transmission assembly 4 is provided, which includes an n-shaped rod 41 fixedly connected to the middle of the inner bottom wall of the oil passing tank 1. Two symmetrically arranged sliding sleeves 42 are slidably sleeved on the outer side of the n-shaped rod 41. One end of each of the two sliding sleeves 42 facing away from each other is fixedly connected to the outer side of the corresponding bracket 5. A vertical plate 43 is fixedly connected to the middle of the top end of the n-shaped rod 41. A motor a44 is fixedly connected to the back of the vertical plate 43. The motor a44 is a forward and reverse motor and can realize the forward and reverse rotation of the transmission rod 45. The output shaft of the motor a44 is fixedly connected to a transmission rod 45. Two symmetrically arranged transmission channels 46 are formed on the transmission rod 45. The transmission channels 46 are all movably sleeved on the outer side of the transmission column 47. The front ends of the transmission columns 47 are all fixedly connected to push-pull rods 48. The bottom ends of the push-pull rods 48 are all connected to the middle of the top end of the bracket 5.

[0038] Among them, the width of the transmission channel 46 is equal to the diameter of the transmission column 47 to prevent the push-pull rod 48 from moving up and down.

[0039] Furthermore, as shown in Figure 4 and Figure 5 it is worth specifically explaining that in order to automatically discharge the powder metallurgy workpieces that have been oil-immersed on the filter screen b51, a pushing-out assembly 6 is provided, which includes a push plate 61 slidably connected to the inner wall of the bracket 5. A baffle 65 is fixed on one side wall of the push plate 61 facing the opening a2 through two symmetrically arranged connecting rods 64. The bottom end of the baffle 65 and the bottom end of the push plate 61 are respectively attached to the top of the filter screen b51. Convex-shaped sliders 62 are fixedly connected to both side walls of the push plate 61. The sliders 62 are all slidably connected to the chutes provided on the inner side walls of the bracket 5. One end of each of the two sliders 62 facing the opening a2 is connected to the inner wall of the chute through a spring 63. The top end of one of the vertical rods is fixedly connected to a toothed plate 66. A gear 67 is meshed above the toothed plate 66. The gear 67 is fixedly connected to the outer side of the output shaft of the motor b68. The motor b68 is fixed to the top edge of the oil passing tank 1 through a support seat.

[0040] Among them, the setting of the spring 63 can prevent the baffle 65 and the push plate 61 from shaking inside the bracket 5 and affecting their lifting actions inside the filter tank.

[0041] In summary: When using this oil passing device for powder metallurgy workpieces, as shown in the attached Figure 1As shown in the figure, first, the powder metallurgy workpieces that have been filtered on the left-side raised state filter screen b51 can be pushed out for unloading. By starting the motor b68 on this side, the gear 67 can be driven to rotate, so that the toothed plate 66 can drive the push plate 61 and the baffle 65 connected by two connecting rods 64 to move towards the opening a2. Thus, the push plate 61 and the baffle 65 can push the powder metallurgy workpieces on the filter screen b51 onto the filter screen a3. And with the setting of the filter screen a3, the oil droplets remaining on the surface of the powder metallurgy workpieces can be filtered and recycled into the oil tank 1, thereby achieving the purpose of convenient unloading. After unloading, the push plate 61 and the baffle 65 connected by two connecting rods 64 are reset to the bracket 5, and then a new batch of powder metallurgy workpieces are placed on the filter screen b51 at this place waiting for oil immersion. By starting the motor a44, the transmission rod 45 is driven to rotate counterclockwise, and with the cooperation of the transmission channel 46 and its two transmission columns 47, the two brackets 5 can be made to lower on the left and rise on the right. Then, the powder metallurgy workpieces on the top of the filter screen of the bracket 5 on the right side can be fished out from the oil in the oil tank 1, and at this time, the powder metallurgy workpieces on the top of the filter screen of the bracket 5 on the left side can be immersed in the oil for oiling, further improving the oiling efficiency and having a good use effect.

[0042] The motor a44 and the motor b68 can be purchased on the market. The motor a44 and the motor b68 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
