Description

Technical Field

[0001] The utility model relates to the technical field of vibration polishing screens, in particular to a vibration polishing screen material separation device. Background Art

[0002] Ferromagnetic special-shaped parts produced by powder metallurgy process will inevitably have burrs on the corners after being stamped by molds. Polishing and deburring them with a vibration polisher is a routine processing procedure, but the polished special-shaped parts are mixed with stainless steel grinding balls in the polishing machine, which are also mixed with failed and deformed grinding balls. The manual separation process is cumbersome and the quality cannot be guaranteed. There is a risk of mixing materials between the previous and subsequent batches. If the failed grinding balls are not cleaned up in time, the polishing efficiency will be low. When separating special-shaped parts with conventional electric screen structures, the parts are easily stuck in the screen, resulting in the stainless steel grinding balls that are expected to be separated not being able to fall quickly. The stuck products need to be cleaned manually, which is time-consuming and may cause mixing. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A first sieve hole is provided at the lower part of the first spiral tube 4, and a plurality of first sieve holes are provided and the plurality of first sieve holes are evenly distributed. The diameter of the first sieve hole is the minimum allowable size of the polishing grinding ball. In the present embodiment, the diameter of the first sieve hole is 5 mm, and the spacing between the first sieve holes is 10 mm. A second sieve hole is provided at the lower part of the second spiral tube 7 near the first spiral tube 4, and a plurality of second sieve holes are provided and the plurality of second sieve holes are evenly distributed. In the present embodiment, the diameter of the second sieve hole is 8 mm, and the spacing between the second sieve holes is 20 mm. The diameter of the second sieve hole is between the size of the sieved material and the size of the polishing grinding ball. A prism 10 is provided between adjacent sieve holes. The prism 10 is a regular polygonal prism, and the side length and height of the prism are twice the size of the sieved material. The second sieve hole connects the upper part of the first spiral tube 4 and the lower part of the second spiral tube 7. The upper end of the second spiral tube 7 is detachably connected with an active magnetic plate 11.

[0025] When the utility model is in use, the driving motor is turned on to ensure that the equipment vibrates regularly. The material is introduced into the tray 9, and the material falls freely into the second spiral tube 7 under vibration. At the same time, in the process of the material moving from the higher end of the second spiral tube 7 to the lower end, the stainless steel grinding balls pass through the second screening holes and fall into the first spiral tube 4. The special-shaped parts are accumulated at the tail end of the second spiral tube 7 and blocked by the second baffle 8. Some parts are adsorbed on the inner wall of the pipe due to the attraction of the active magnetic plate 11.

The fallen stainless steel grinding balls will vibrate and screen again after entering the first spiral tube 4.

Unqualified grinding balls will fall into the first storage box 5, and qualified grinding balls will accumulate at the tail end of the first spiral tube 4 and be blocked by the first baffle 6. After the screening is completed, the first baffle 6 is opened first to take out the qualified grinding balls, and then the second baffle 8 is opened and the movable magnetic plate 11 is moved away to take out the parts, and the screening work is completed.
