Problems solved by technology
[0002] In powder metallurgy processing, especially when it involves the compression molding of multi-step complex powder products, it is generally processed in the form of multiple pressurization, so a reasonable setting of the pressurization mechanism is required, but due to the multiple pressurization involved, it often leads to pressurization. The structure of the mechanism is complex, easy to damage, and inconvenient to adjust; at the same time, the design of the existing pressurization mechanism is unreasonable, resulting in unsatisfactory product quality, and the uniformity of product density and the stability of product quality cannot be effectively guaranteed, so further improvement is needed

Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention is applied on the complete machine and is described, so that understand the present invention better.
[0027] working principle:
[0028] This machine is mainly used for compact powder products with small tonnage and multi-steps, and it is realized by adopting the female mold floating structure in the form of mold base. Its basic working principle is:
[0029] Install the formwork 1 on the working surface 20 of the machine formwork, connect the upper and lower connection plates 21 of the formwork 1 through the upper connecting plate 21 and the lower T-shaped head 19, and then drive the upper sliding column 24 to move downward by the upper pressing beam 22 , to complete the pressurization process.
[0030] The action of the upper pressure beam 22 is driven by the input power to rotate the pressurization cam 5, and then the pressurization cam 5 drives the pressurization lever 4 to drive the downward ...

The invention relates to a pressing mechanism of a powder forming machine. A mold frame is arranged on a mounting working tabletop, and includes an upper pressing pull rod capable of moving up and down; the upper part of the upper pressing pull rod is connected with an upper pressing cross beam and an upper slide column for synchronously moving along with the upper pressing pull rod; the upper slide column drives an upper mold punch to move up and down; the upper pressing pull rod is connected with a pressing cross beam; the pressing cross beam is provided with a pressing lever and a pressing cam for driving the pressing cross beam; a lower slide column corresponding to the upper slide column is arranged at the lower part of the upper slide column, and is provided with a female mold for moving along with the lower slide column; a connecting structure rotationally connected with the pressing cross beam is arranged on the lower slide column; a stopper mechanism is arranged at the lower part of the lower slide column, and includes a stopper lever capable of moving to stop the lower slide column; and the stopper lever is driven by a stopper cam to rotate. The pressing mechanism of the powder forming machine, provided by the invention, is compact and tensioned in structure, and can satisfy the machining requirements of multistep complex powder products.
