Abstract

The invention relates to a powder feeding device of a powder hydraulic press, comprising a guide rail fixed on a product support plate and a feeding cylinder, a feeding bracket slidably installed on the guide rail, a feeding box fixed on the feeding bracket, the feeding bracket and the feeding cylinder The push rod end is fixedly connected, and it is characterized in that: the vibration cylinder is fixed on the side wall of the feed box perpendicular to the guide rail, and the push rod end of the vibration cylinder is fixedly connected with a vibration grid, and the vibration grid is located in the feed box. The invention adopts a vibrating cylinder and a vibrating grid. During the process of filling the powder raw material into the cavity of the mold, the vibrating cylinder pushes the grid to reciprocate and vibrate, so that the powder raw material evenly falls into the cavity, ensuring the uniformity of powder raw material filling and facilitating subsequent pressing. forming.

Description

technical field [0001] The invention relates to a powder feeding device of a powder hydraulic press. Background technique [0002] The powder feeding device is a necessary structure for conveying the powder raw material from the hopper to the mold cavity in the powder hydraulic press. At present, the commonly used powder feeding device consists of a guide rail and a feeding cylinder fixed on the product support plate, and a feeding bracket slidingly installed on the guide rail. 1. It consists of a feeding box installed on the feeding bracket, and the push rod end of the feeding cylinder is fixedly connected with the feeding bracket. When feeding, the feeding cylinder pushes the feeding bracket to move along the guide rail to the material inlet of the mold cavity, and the powder raw material falls into the cavity under the action of its own gravity, and the powder can be continuously filled under the reciprocating motion of the feeding box driven by the feeding cylinder. Int...
