Electromagnetically driven powder compacting device

Abstract

The invention discloses an electromagnetically driven powder compacting device which comprises a base, an upper mounting plate, a mold, a compacting punch and a flat plate coil, wherein a bracket is fixedly arranged on the base, the upper mounting plate is fixedly connected with the upper end of the bracket, the flat plate coil is fixedly arranged on the upper mounting plate; the electromagnetically driven powder compacting device is characterized in that a guide plate is arranged at the upper end of the compacting punch, a metal driving sheet is fixedly arranged on the upper end surface of the guide plate, a first guide rod is fixedly arranged on the base, the guide plate is sleeved on the first guide rod, a first spring is sleeved on the first guide rod, a floating plate is arranged in the base, the mold is placed on the floating plate, a core rod is fixedly arranged on the base, the core rod is penetrated through the floating plate and extended into the mold, a positioning mechanism is arranged on the compacting punch, and an elastic adjusting mechanism is arranged between the floating plate and the base. The invention has the advantages that the compacted finished products have high quality due to two-direction compacting of the powder, and the gap between the metal driving sheet and the flat plate coil can be adjusted through rotational adjustment of a nut, thereby controlling the electromagnetic driving force applied to the compacting punch.

Description

technical field [0001] The invention relates to a powder forming processing device, in particular to an electromagnetically driven powder pressing device. Background technique [0002] In the field of powder metallurgy, there are many methods of powder compaction, such as dry pressing, isostatic pressing, and injection molding. These methods basically mix metal powder or ceramic powder with binder to form a uniform feed, and then obtain metallurgical products with a certain density by pressing, but these methods have low molding efficiency, high cost, and environmental protection. The performance is poor and the mechanical equipment used is expensive. [0003] At present, electromagnetically driven powder pressing devices have begun to enter people's field of vision, but the current electromagnetically driven powder pressing devices have relatively poor controllability, and unidirectional pressing is generally used, resulting in poor quality of pressed products.
