Feeding device of a powder compression molding machine

Abstract

The invention provides a feeding device of a powder compression molding machine, which belongs to the technical field of machinery. It solves the problems of poor stability, complex structure and the like during feeding of existing powder compression molding machines. The feeding device of the powder molding machine includes a feeding cylinder and a rotating shaft. The inner end of the rotating shaft is located in the feeding cylinder, and the outer end of the rotating shaft passes through the feeding cylinder to connect with the motor. The bottom of the feeding cylinder has a discharge The inner end of the rotating shaft is fixedly connected with a sheet-shaped scraper, the scraper is located at the outlet of the feeding cylinder, and the scraper is fixed in parallel with the side of the rotating shaft through a connecting rod. The feeding device of the powder compression molding machine first breaks the accumulated powder raw materials into lumps through the crushing teeth, which ensures stable and high feeding. In addition, the device has simple structure, low cost and high practicability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a powder compression molding machine, in particular to a feeding device of the powder compression molding machine. Background technique [0002] The workpiece made of powder raw material die-casting has simple manufacturing process and low manufacturing cost. Therefore, powder compression molding machines are widely used in machining. [0003] Generally, a powder compression molding machine includes a mold and a stamping head located on the upper part of the mold, and the powder raw material at the mold can be pressed into shape by pressing down the stamping head. [0004] For the convenience of feeding, there is a stirring device for stirring the powder raw materials in the feeding cylinder, so that although the powder raw materials can pass through the feeding cylinder smoothly, the amount of powder raw materials cannot be controlled, and the feeding cylinder will still be dam...

AI Technical Summary

Problems solved by technology

[0004] For the convenience of feeding, there is a stirring device for stirring the powder raw materials in the feeding cylinder, so that although the powder raw materials can pass through the feeding cylinder smoothly, the amount of powder raw materials cannot be controlled, and the feeding cylinder will still be damaged due to the Too much powder raw material makes part of the powder raw material compacted into lumps

Apparently lumpy powder raw materials can affect feeding stability

[0005] At the same time, too much powder raw material accumulated at the discharge port is not easy to enter the molding cavity of the mold, and it cannot be guaranteed that there is always an appropriate amount of powder raw material at the discharge port, which makes the processed workpiece size inconsistent and affects its yield.
