[0001] The utility model relates to the technical field of powder metallurgy bearing parts, in particular to a device for removing residual powder from the inner diameter of a powder metallurgy slender hollow bearing part. Background Art

[0002] As Figure 5 shown, an inner hole is provided inside an existing powder metallurgy slender hollow bearing part, and this part is a powder metallurgy product with a full length of more than 15 MM, a wall thickness of more than 3 MM, and an inner diameter of within 3 MM.

[0003] After demolding, such powder metallurgy slender hollow bearing parts are pushed out by a powder feeder. The parts slide down to the blanking plate through the inertia of the powder feeder's material pushing and the slope at the mouth of the middle die pressing plate, and then through the buffering of the buffer strip, the sliding speed of the parts decreases, and they slowly slide through the pore plate and finally slide into the receiving tray.

[0004] During the above entire process, it is necessary to remove the residual powder on the bearing parts. In the prior art, the powder is often removed by a wind powder blowing mechanism. However, due to the inner hole provided in the slender hollow bearing part, its inner diameter often remains with powder, and when the subsequent powder blower blows the residual powder conventionally, it cannot blow to the inner diameter of the part, and the residual powder in the inner diameter cannot be effectively removed, thus causing the loss of the part's functionality and having a greater impact on subsequent assembly work and the like.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a device for removing residual powder from the inner diameter of a powder metallurgy slender hollow bearing part with a reasonable structure. Summary of the Utility Model

[0027] The following further clarifies the present utility model in conjunction with the drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0028] As Figure 1 shown, a device for removing residual powder inside the diameter of a powder metallurgy slender hollow bearing part includes a feeding platform 1. A feeding track 3 adapted to the size of the bearing part 2 is provided on the feeding platform 1, and the bearing part 2 can be correspondingly placed in the feeding track 3 to achieve feeding;

[0029] A baffle plate 4 is further provided on the feeding platform 1. The baffle plate 4 is arranged directly below the feeding track 3. The bearing part 2 in the feeding track 3 correspondingly falls on the baffle plate 4. The plate body of the baffle plate 4 extends to the left, and a feeding gap 5 is left between the baffle plate 4 and the left side of the feeding platform 1;

[0030] On the right side of the material baffle 4, a material pushing mechanism 7 is provided. Above the left side of the material baffle 4, a material blowing mechanism is provided. After the bearing parts 2 in the blanking track 3 fall on the material baffle 4, the material pushing mechanism 7 on the right side correspondingly pushes the bearing parts 2 to the left side of the material baffle 4, so that the bearing parts 2 are in correspondence with the position of the material blowing mechanism. The material blowing mechanism blows air into the inner diameter of the bearing parts 2 to remove the residual powder in the inner diameter. Then, the bearing parts 2 are blanked from the blanking gap 5 on the left side.

[0031] The placement angle of the blanking platform 1 is 0 - 90°; the material pushing mechanism 7 is set as a cylinder assembly. A push plate 71 is installed on the shaft body of the material pushing mechanism 7. The size of the push plate 71 is adapted to the size of the bearing parts 2 and can correspondingly extend into the area between the material baffle 4 and the blanking track 3 to push the bearing parts 2 to the left.

[0032] An installation plate 8 is provided on the material pushing mechanism 7, and an installation groove 9 is provided on the installation plate 8. The material pushing mechanism 7 is fixed on the blanking platform 1 through the installation plate 8 and the installation groove 9.

[0033] As Figure 3 and Figure 4 shown, the material blowing mechanism includes an installation seat 10 and a material blowing fan 11. The installation seat 10 is located above the left side of the material baffle 4, and a plurality of evenly spaced material blowing channels 12 aligned with the bearing parts 2 are provided in the installation seat 10. And an exhaust groove 13 corresponding to the position of the bearing parts 2 is provided on the material baffle 4;

[0034] As Figure 2 shown, the material blowing fan 11 is correspondingly connected to the material blowing channels 12 in the installation seat 10. The air flow generated by the material blowing fan 11 is discharged through the material blowing channels 12 to blow the bearing parts 2 to remove powder, and the air flow enters the inner hole of the bearing parts 2 to blow the residual powder in the inner hole to remove powder. Finally, the air flow is discharged from the exhaust groove 13 of the material baffle 4.

[0035] An installation plate 8 is also connected and provided on the installation seat 10, and an installation groove 9 is provided on the installation plate 8; and a flow control valve 6 is also provided on the material blowing fan 11.

[0036] Installation plates 8 are provided on both the blanking track 3 and the material baffle 4, and installation grooves 9 are provided on the installation plates 8. They are fixed on the blanking platform 1 through the installation plates 8 and the installation grooves 9.

[0037] The working principle of this device is as follows: First, the setting of the blanking platform of this device can be set according to the actual situation of the workshop. The blanking platform can be placed horizontally, vertically or obliquely accordingly. When placed obliquely, the placement angle can be selected.

[0038] After the bearing parts are unloaded from the blanking track, they will correspondingly fall on the baffle plate. After falling on the baffle plate, the pushing device on the right will correspondingly push the bearing parts to the left through the push plate, and push the bearing parts below the blowing mechanism. In this process, the size of the push plate needs to be set accordingly, so that when the push plate pushes the bearing parts to the left, the bearing parts in the upper blanking track will not fall down. And when the push plate pushes the bearing parts in place and then returns to the original position from the right, the upper bearing parts can correspondingly fall on the baffle plate.

[0039] And when the bearing parts are pushed to the left on the baffle plate, they will be correspondingly located between the blowing mechanism and the baffle plate. There is a blowing channel in the mounting seat of the blowing mechanism. The blowing channel is connected to the blowing fan, so that the bearing parts on the baffle plate can be blown with powder. At the same time, exhaust slots corresponding to the positions of the blowing channel and the inner holes of the bearing parts also need to be set on the baffle plate. The specific structural setting is as Figure 2 shown. The air flow in the blowing channel passes through the inner hole of the bearing part and then discharges from the exhaust slot of the baffle plate, so as to be able to remove the residual powder inside the diameter of the bearing part.

[0040] And while the bearing parts are being blown, the pushing mechanism on the right continuously pushes the materials. All the bearing parts passing below the blowing mechanism are correspondingly blown with powder, and then are unloaded through the blanking gap on the left, completing the blowing work of the residual powder inside the diameter of the bearing parts.

[0041] And in the above process, a plurality of evenly spaced blowing channels need to be set in the mounting seat, so as to be able to blow the bearing parts efficiently; in addition, each component is correspondingly provided with a mounting plate and a mounting groove, and the overall structure is very convenient for installation and disassembly.

[0042] The above specific implementation manner is only a preferred embodiment of the present invention, and is not used to limit the implementation and the scope of the claims of the present invention. All equivalent changes and modifications made in accordance with the content of the patent protection scope of the present invention shall be included within the scope of the patent application of the present invention.
