Description

Technical Field

[0001] The invention relates to the field of powder metallurgy, and in particular to an automatic material unloading mechanism for powder metallurgy processing. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder or a mixture of metal powder and non-metal powder as raw materials, and then forms and sinters them to manufacture metal materials, composite materials and various types of products. It plays a pivotal role in the development of new materials. At present, powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, and has become one of the most dynamic branches in new materials science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability. Patent: CN216176617U discloses a powder metallurgy processing table, which relates to the field of powder metallurgy technology, including a base, an upper portion of the right side of the base is provided with an empty slot, and a support table is fixedly installed on the inner bottom wall of the empty slot. The powder metallurgy processing table uses a metallurgical powder spreading device to spread powder into the interior of a molding groove, and uses a pressing device to press and mold the powder in the molding groove, and uses a center column to press the center position of the molded part into a center hole, and uses the molding groove to press the outer ring of the molded part into a tooth shape. After molding, the push column is pushed upward by extending the telescopic end of the electric telescopic rod to push the molded part upward, and the molded part and excess powder are pushed to the left by the powder spreading device. The molded part and excess powder are guided by the slope of the base, and the powder falls into the guide cover through the unloading trough, and is introduced into the interior of the powder receiving trough through the guide trough for collection. The molded part slides down to the interior of the receiving trough, which improves the unloading effect of the device; In the above technology, after the molded part is ejected from the molding trough, it is not easy to slide directly into the receiving trough through the bottom slope, and the screening effect is poor if the powder is simply screened through the lower powder trough, which needs to be improved.
