Multilayer powder-feeding device for powder forming machines

Abstract

The invention discloses a multilayer powder-feeding device for powder forming machines, and the multilayer powder-feeding device is characterized in that a roller fixed on a powder feed arm is matched with a cam arranged on a camshaft, the powder feed arm is connected with one end of a support, and the other end of the support is connected with a powder hopper; the cam is composed of a cam seat and more than one cam sheets, and the cam sheets are fixed on the cam seat; and the powder hopper is a combined powder hopper consisting of more than one single powder hopper. The cam is prepared into a split cam; because the curve shapes of the cam sheets are different, the curve diversity of the cam sheets is realized, and the cam sheets can be subjected to overlapping, splitting and transpose combination so as to obtain different adjustable curve integrals for the powder filling of more than two types of materials at different speeds, therefore, the application range of the cam sheets is greatly expanded, each link of the powder feeding process is displayed more clearly, the stop time of powder feeding is more concrete, and the stop time of powder loading is more accurate so as to ensurethe accuracy and smoothness of powder filling and satisfy the requirements that the powder loading of different products is implemented by using a plurality of powder hoppers. By using the multilayerpowder-feeding device, the current situation that a powder forming machine only can be used for processing one type of material stamping is changed, the quality is good, and the performance is stable.

Description

technical field [0001] The invention relates to a main part of a powder forming machine, especially a multi-layer powder feeding device for a powder forming machine that can automatically convey powder of one or more than one different materials and is used for pressing powder products with a multi-layer structure. Background technique [0002] The powder forming machine can produce and process products with less cutting and no cutting, so it is favored by various enterprises. However, most of the powder forming machines currently on the market and used by enterprises can only press powder products made of one material, and cannot press powder products made of multiple materials. Therefore, the existing powder forming machines can no longer meet the needs of manufacturers. development needs. [0003] At the same time, the powder feeding device of the existing powder molding machine still has the following deficiencies. When the cylinder works at the two limit positions of t...

However, most of the powder forming machines currently on the market and used by enterprises can only press powder products made of one material, and cannot press powder products made of multiple materials. Therefore, the existing powder forming machines can no longer meet the needs of manufacturers. development needs

[0003] At the same time, the powder feeding device of the existing powder molding machine still has the following deficiencies. When the cylinder works at the two limit positions of the inflection point, a collision phenomenon will occur, which has a great impact on the smooth completion of powder loading. During the process, there is no obvious intermediate pause for powder feeding time or the pause time is insufficient, and the pause position is difficult to control and many other disadvantages, resulting in unstable powder loading and uneven powder loading, which will directly affect the quality of the pressed product. quality
