A reverse push type powder compact forming device

Abstract

The invention relates to the technical field of intelligent manufacturing, and discloses a reverse push-type powder compact forming device, which includes a lower bracket, the top of the lower bracket is clamped with a compact device, and the top of the inner cavity of the compact device is provided with A demoulding mechanism, and an upper bracket is fixedly installed on the top of the compacting device, and a feeding system is fixedly sleeved in the inner cavity of the upper bracket, and the inside of the feeding system and the inside of the compacting device are connected to each other. The reverse-push powder compact forming device, through the compact compact device and the setting of the feeding system, gradually adds powdery raw materials during the compacting process, so that the parts are gradually compacted and formed. Compared with the existing compact compact device, it is no longer The method of first filling the raw materials at one time and then pressing and forming makes the parts gradually filled and pressed, which effectively ensures the uniformity of the density of each part in the compacted parts, ensures the quality of the compacted parts, and at the same time ensures the size of the compacted parts the accuracy.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a reverse push type powder compact forming device. Background technique [0002] The compacting process in powder metallurgy is a key step to ensure the quality of product parts, but for a long time the density of the compact does not meet the design requirements, and the shape and position tolerance of the compact cannot meet the design requirements, which has always affected powder metallurgy. products industry. [0003] At present, powder compaction molding is mainly divided into upper and lower synchronous and isostatic pressing methods. However, if the upper and lower synchronous pressure is applied, there will be a large difference in the density between different positions on the compact part (especially between the middle and both sides) , thus seriously affecting the quality of the green parts, and in the process of isostatic pressing, due to the need ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a reverse-push powder compact forming device, which has the advantages of good density uniformity, high quality, small shape and position tolerance, and high dimensional accuracy of compact parts, and solves the problem of existing problems. There are differences in the density between different positions (especially between the middle and both sides) of the green compacting device, and the isostatic pressing process will easily lead to the shape and position tolerance of the green compact and The size of the compact is not easy to accurately control, the production efficiency is low, and the accuracy of the compact parts is poor
