Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy parts, in particular to a powder cleaning device for powder metallurgy parts. Background Art

[0002] Some gear parts with hollow structures in the middle are usually produced using powder metallurgy technology due to their complex structures. After the above parts are pressed and formed by powder, they are placed on a conveyor belt by a robot. A rotating brush mechanism is set on one side of the conveyor belt. The rotating brush mechanism can clean the residual powder on the surface of the pressed parts, so that burrs are not easily formed on the surface of the parts during subsequent firing.

[0003] The existing rotating brush mechanism uses a motor to drive the brush to rotate to achieve the cleaning of the powder on the surface of the parts. The mechanism cleans the parts passing by one by one. However, after the brush cleans one part, some powder will adhere to the brush and cannot be cleaned in time. When the next part moves to the position of the rotating brush mechanism, the brush with powder attached will have a poor cleaning effect on the part. If this continues for a long time, the powder attached to the brush will reach a limit value, further reducing the cleaning effect of the brush on the powder on the surface of the part.

Two groups of powder cleaning brush assemblies 1 are arranged at intervals, and both groups of powder cleaning brush assemblies 1 are connected to the rotating lifting assembly 2 and are lifted or rotated under the drive of the rotating lifting assembly 2. When any group of powder cleaning brush assemblies 1 is cleaning the powder on the parts, the other group of powder cleaning brush assemblies 1 is located at the powder cleaning and collecting assembly 3 for cleaning, and the powder cleaning and collecting assembly 3 can clean and collect the powder attached to the powder cleaning brush assembly 1.

[0032] A conveyor belt 4 is provided below a set of powder cleaning brush assemblies 1. The pressed parts are placed on the conveyor belt 4 by a robot. The conveyor belt 4 is used to convey the pressed parts and move the parts intermittently. The powder cleaning brush assembly 1 can clean the stopped parts to remove the powder remaining on the parts.

[0033] A base is provided below the conveyor belt 4 , and the rotating lifting assembly 2 and the powder cleaning and collecting assembly 3 are both installed on the top of the base, and the rotating lifting assembly 2 is located between the conveyor belt 4 and the powder cleaning and collecting assembly 3 .

[0034] Reference Figure 1 and Figure 2 The rotary lifting assembly 2 includes a rotary motor 21 and a lifting cylinder 22. The cylinder body of the lifting cylinder 22 is fixedly mounted on the top of the base, and a connecting plate 23 is fixedly mounted on the telescopic rod of the lifting cylinder 22.

A rotating plate 24 is mounted on the motor shaft of the rotary motor 21, and two sets of powder cleaning brush assemblies 1 are installed on the rotating plate 24 at intervals. The rotary motor 21 can drive the rotating plate 24 to swing back and forth, that is, the rotary motor 21 can drive the rotating plate 24 to rotate forward a certain angle first and then reverse back, so that the cables connected to the powder cleaning brush assembly 1 are not easily entangled.

[0035] The two groups of powder cleaning brush assemblies 1 have the same structure, and one group is used as an example for explanation below. The powder cleaning brush assembly 1 includes a brush 11 and a drive motor 12. The drive motor 12 is fixedly installed on the top of the rotating plate 24, and the motor shaft of the drive motor 12 passes through the rotating plate 24 and is located below the rotating plate 24. The brush 11 is located below the rotating plate 24 and is connected to the motor shaft of the drive motor 12. The drive motor 12 can drive the brush 11 to rotate to clean the powder on the parts. After the lifting cylinder 22 drives the rotating plate 24 to descend, the brush 11 can be more closely attached to the top of the part to improve the cleaning effect. After the lifting cylinder 22 drives the rotating plate 24 to rise, the brush 11 can be prevented from interfering with the transportation of the cleaned parts.

[0036] When any group of brushes 11 cleans the parts on the conveyor belt 4, the other group of brushes 11 is located at the powder cleaning and collecting assembly 3 to clean the powder attached to itself through the powder cleaning and collecting assembly 3. The rotating plate 24 rotates in a reciprocating swing rather than rotating counterclockwise or clockwise, so that the cables connected to the drive motor 12 are not easily entangled.

When moving, the plurality of toggle plates 32 toggle the brush 11 so that the powder attached to the brush 11 falls into the collection box 31. The vacuum cleaner 34 can absorb the powder in the collection box 31.

[0038] Reference Figure 3 and Figure 4Specifically, an opening is provided at the top of the material collection box 31 to facilitate the insertion of the brush 11 into the material collection box 31.

At the same time, the toggle plates 32 are arranged at intervals with the bottom side of the material collection box 31, so that the toggle plates 32 will not form a partition on the space at the bottom of the material collection box 31, and when the vacuum cleaner 34 sucks the powder inside the material collection box 31, it is smoother and cleaner.

[0039] Combination Figure 2 Reference Figure 3 and Figure 4 Two guide rails 36 are arranged at intervals, and two corresponding linkage bars 35 are also arranged at intervals, and the two linkage bars 35 correspond to the two guide rails 36 one by one. The two linkage bars 35 are connected to the toggle plate 32 and move synchronously, and the brush 11 is located above the two linkage bars 35, so that the dust on the brush 11 will fall between the two guide rails 36 after falling off, which is convenient for cleaning.

The docking port is communicated with the interior of the material collecting box 31 . The dust collector head 341 is inserted into the docking port with interference fit.

[0042] The implementation principle of a powder cleaning device for powder metallurgy parts in the embodiment of the present application is as follows: after the brush 11 has cleaned the powder on a part, the rotating lifting assembly 2 can rotate the corresponding brush 11 to the top of the collection box 31 and insert it into the collection box 31. At this time, the servo motor 33 drives the toggle plate 32 to move. The toggle plate 32 will toggle the bristles on the brush 11 to swing during the movement, so that the powder attached to the brush 11 falls off into the collection box 31, so that the brush 11 can clean the new parts more cleanly when cleaning again. The powder in the collection box 31 will be sucked away by the vacuum cleaner 34 to avoid the powder from floating due to the airflow generated during the movement of the toggle plate 32. When the brushes 11 in one group are cleaning the parts on the conveyor belt 4, the brushes 11 in the other group can be inserted into the collection box 31 for cleaning, thereby improving work efficiency.
