Description

Technical Field

[0001] The present invention relates to a powder forming machine, in particular to a filling adjustment mechanism of the powder forming machine and the powder forming machine comprising the mechanism. Background Art

[0002] Powder forming machines are highly favored by businesses due to their ability to produce high-precision, smooth parts in a single press, along with their wide range of applications, high production efficiency, and material utilization. They are now widely used to press various powder products made from metals, ceramics, bakelite, and other materials. The shapes of these pressed products are becoming increasingly complex, with multi-stepped parts, multiple through-holes, and multiple internally stepped blind holes all now possible. With the development of new-generation communication technologies, particularly 5G technology, complex-shaped thin-walled ceramic products are increasingly being used in 5G equipment, and their shapes are becoming increasingly complex.

[0003] Filling, powder transfer, and forming are key steps in the powder forming process. During these steps, the floating punch plate must be adjusted to different positions according to the different steps. Therefore, the filling adjustment mechanism is a key component of the powder forming machine. Existing four-down punch mechanisms only have two floating punch plates, and the filling adjustment mechanism can be symmetrically positioned on each punch plate. However, in a five-down punch mechanism, there are three floating punch plates. Properly designing the filling adjustment mechanism has always been a difficult problem in powder forming machine design.

[0004] Therefore, technicians in this field are committed to developing a filling adjustment mechanism suitable for the lower five-punch mechanism of a powder forming machine to ensure uniform density of complex parts pressed products, simple and convenient operation and adjustment, which not only reduces labor intensity, but also improves work efficiency, and can reduce production costs and save materials.
