Abstract

The invention relates to a powder weighing mechanism and a one-die multi-piece magnetic field press with the same, in particular to a powder weighing mechanism and a one-die multi-piece magnetic field press. The problem that an existing powder weighing mechanism is low in automatic accurate weighing efficiency is solved, and the problem that due to the fact that a one-die multi-piece magnetic field press is low in automatic accurate weighing efficiency of magnetic powder, constant-volume feeding is not adopted, and the weight error of the magnetic powder in each piece die cavity is large is solved. According to the powder weighing mechanism, one-time pulling plate type main feeding is combined with electromagnetic vibration feeder supplementary feeding, the powder accurate weighing efficiency is greatly improved, and the powder weighing mechanism is suitable for the powder forming field of ceramics, hard alloy, metal structural parts, ferrite magnetic materials and the like, and is particularly suitable for a one-mold multi-part magnetic field press. According to the one-die multi-piece magnetic field press, the interior of the feeding bin of the feeding mechanism is divided into the multiple feeding branch bins corresponding to the die cavities in a one-to-one mode, it is guaranteed that the weights of magnetic powder in the die cavities are consistent, and therefore the magnetic powder is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to a powder weighing mechanism and a one-mould multi-piece magnetic field press with the weighing mechanism, in particular to a powder weighing mechanism and a one-mould multi-piece magnetic field press. Background technique [0002] Due to the low efficiency of automatic accurate weighing of magnetic powder, the existing one-die multi-piece magnetic field press generally adopts constant volume feeding, that is, first weigh the total weight of multiple pieces of magnetic powder (such as six pieces, each 100 grams, a total of 600 grams), and then, All the magnetic powder (600g) is filled (i.e. constant volume) of each mold cavity through the feeding mechanism. Due to the poor fluidity of the magnetic powder, although each mold cavity is filled (constant volume), the weight error of the magnetic powder in each mold cavity is relatively large. The shape and other performances are particularly prominent, resulting in the deviation of...
