Powder transferring control device of powder forming machine

Abstract

The invention relates to a novel powder transferring control device of a powder forming machine, which is symmetrically arranged at the front side and the rear side of a mould base. Each of the front side and the rear side comprise a powder transferring cylinder connected with an upper plate, and the lower part of a piston rod of the powder transferring cylinder is connected with a stretching screw. A powder transferring thread sleeve is sleeved outside the stretching screw, the inside of the powder transferring thread sleeve extends downwards to form a powder transferring bolt, and a powder transferring limiting seat for limiting the downward displacement of the powder transferring thread sleeve is arranged under the powder transferring thread sleeve. The inside of the powder transferring limiting seat extends upwards to form a bolt matched with the powder transferring bolt, and the lower part of the powder transferring limiting seat is connected with a reset cylinder fixedly connected with a lower fixed punching plate. A piston rod of the reset cylinder extends into the powder transferring limiting seat and is connected with a floating punching plate of the forming machine through a bolt. The invention has the advantages that firstly, the transferring force is stable and reliable, and secondly, the adjustment of the powder transferring time and the powder transferring distance are simple and convenient, and the installation and the debugging are convenient.

Description

technical field [0001] The invention relates to the technical field of powder molding machines, in particular to a novel powder transfer control device for powder molding machines. Background technique [0002] During the forming process of powder metallurgy products. When using a uniaxial rigid mold to press and form multi-step, complex parts, such as H-shaped products, before pressing and forming, the powder must be correctly arranged in each corresponding position in the press mold through the powder transfer device. Otherwise, various shear cracks will appear in the compact during press molding. The powder loading of the powder molding machine is to move the molding machine to an appropriate position and load the powder through the powder feeding device. The height of the powder loading is controlled by the powder transfer control device. The transfer time and transfer distance are controlled according to the needs. The control device is generally installed inside the ...

Problems solved by technology

The powder loading of the powder molding machine is to move the molding machine to an appropriate position and load the powder through the powder feeding device. The height of the powder loading is controlled by the powder transfer control device, and the transfer time and transfer distance are controlled according to the needs. The control device is generally installed inside the formwork, which is extremely inconvenient during installation and debugging, and the mechanism is complicated, and the transfer time and distance are unstable.
