The invention relates to a quantitative feeding device for a full-automatic magnetic powder molding press. The quantitative feeding device comprises a corrugated pipe, a charging barrel, a vibration hammer, a connecting pipe, a smashing device and a weighing and feeding device, wherein a pressure sensor in the weighing and feeding device is fixed on a support plate; the back part of the support plate is provided with a cylinder fixing frame for fixedly connecting a fixed point for a guide cylinder; a support point on the front side of a weighing hopper is connected with a bracket 1; a support point on the back side of the weighing hopper is connected with a connector; the connector is connected with a cylinder pull rod; under the initial contraction action of the cylinder, the weighing hopper is positioned on the pressure sensor for weighing; under the extension action of the cylinder, the hopper is overturned for feeding; magnetic powder is conveyed to an inner container of a feeding box through a material receiving pipe; the inner container of the feeding box is fixed in a feeding box frame in a floating way; a feeding plate is connected below the feeding box frame; the feeding hole of the feeding plate is aligned with the blanking port of the inner container of a material box; the front part of the feeding box frame is provided with a vibrator 2; and the back part of the feeding box frame is connected with a feeding oil cylinder. The quantitative feeding device is mainly applied to powder molding manufacturing of a magnetic material, so that an automatic weighing and feeding device is realized.
Description
technical field [0001] The invention relates to rare earth magnetic powder processing equipment, in particular to a quantitative feeding device for a fully automatic magnetic powder forming press. Background technique [0002] The automatic magnetic powder powder molding press is mainly used for powder molding of magnetic materials. To realize automatic precision molding manufacturing, three problems must be solved: system accuracy, quantitative feeding, and pressing methods. The most difficult problem is quantitative feeding. The viscosity of the magnetic powder material is very high, coupled with the high mesh number of the powder particles (the NdFeB magnetic powder imported from Japan can be as small as the particle diameter is only 3μm), it tends to agglomerate, which is not conducive to molding processing. In the past, the magnetic powder press was manually fed, and the automatic method could not be realized. The so-called automatic powder molding press imported from ...
