AI Technical Summary

Technical Problem

Existing powder metallurgy mixing processes have limited premixing effects, resulting in insufficient mixing of raw materials in all directions, making it difficult to achieve uniformity and consistency.

Method used

The lifting mechanism alternately pulls the rope upwards, causing the mixing disc to tilt in different directions. Combined with the partition separating the storage cylinder and the quantitative discharge hole, it realizes multi-directional rolling premixing and quantitative feeding of raw materials, and then the final mixing is carried out by the stirring rod.

Benefits of technology

It significantly improves the premixing uniformity and efficiency of raw material powders, ensuring the quality and consistency of subsequent mixing, and is suitable for industrial continuous production.

Abstract

本发明属于粉末冶金技术领域,涉及一种粉末冶金工艺。本发明包括原料粉末的准备。之后,将原料粉末通过加料管投入到混合罐内的混料盘上,进行预混。然后,使预混物料落入混合罐内进行最终混合。之后,将混合均匀的原料粉末放入模具中,压制成型。对压坯进行烧结。混料盘向不同方向的倾斜,原料粉末向多个方向运动,能够有效打破原料粉末之间的团聚,促进不同种类原料粉末的均匀交织,显著提升预混的均匀度和效率。预混后,使混料盘上的原料粉末从混料盘边缘均匀撒入混合罐内,使原料粉末在混合罐内呈分散状态落入,避免了局部堆积,为后续的进一步混合创造了有利条件,有助于缩短最终混合时间,提高混合质量。
