Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder metallurgy technology, specifically to a powder metallurgy part surface powder blowing and brushing device. Background Technology
[0002] Powder metallurgy is a process that uses metal powder or a mixture of metal and non-metal powders to manufacture parts through pressing and sintering. During the production of powder metallurgy parts, some loose powder particles may remain on the surface of the parts due to processes such as forming, demolding, and sintering. This is called "floating powder". Floating powder not only affects the appearance quality of the parts, but may also affect their performance, such as causing friction or dimensional instability during assembly. Therefore, effective surface floating powder blowing is one of the most important processing steps in powder metallurgy.
[0003] In existing technologies, powder cleaning is often performed during the automatic transport process using a conveyor device. While this method is highly efficient, multiple powder metallurgy parts can easily come into contact with each other on the conveyor device, resulting in low powder cleaning efficiency. Furthermore, the contact area between the powder metallurgy parts and the conveyor belt is not effectively cleaned. Therefore, it is necessary to develop an improved powder cleaning device for powder metallurgy parts to address these issues. Utility Model Content

A limit rod 616 is fixedly connected inside the connecting platform 613. A limit block 617 is slidably connected to the outside of the limit rod 616, which facilitates the adjustment of the opening and closing degree of the guide plate 612, thereby satisfying the limit transmission of powder metallurgy parts of different sizes entering the conveyor 3.
[0028] Furthermore, the limiting block 617 is threadedly connected to the bidirectional threaded rod 615, the limiting block 617 is slidably connected to the connecting platform 613, and the guide plate 612 is provided with a groove at the corresponding position of the limiting block 617, and the limiting block 617 is in contact with the guide plate 612, which facilitates a more stable feeding process.
[0029] Furthermore, the dust removal assembly 62 includes a first connecting frame 621, which is fixedly connected to the top of the mounting platform 1.

Example
[0031] Based on Embodiment 1, in the prior art, the contact area between the powder metallurgy parts and the conveyor belt is not effectively cleaned due to contact. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 5 Furthermore, in conjunction with Embodiment 1, the movable feeding mechanism 7 includes a support base 71, which is fixedly connected to the front of the mounting platform 1.

In conjunction with the damping rod 627 and the spring 628, the second rotating block 629 rotates inside the third fixed block 6210. In conjunction with the operation of the blower 5, air is blown onto the powder metallurgy parts. When the powder metallurgy parts move onto the feeding rack 74, the second motor 72 operates, causing the connecting block 73 to rotate. In conjunction with the limit plate 75, the feeding rack 74 rotates. The floating powder generated during the blowing process falls into the dust collection box 2 under the action of gravity and the blower 5, thus facilitating subsequent processing by the staff.
