Problems solved by technology
The existing compression molding device has uneven density in the axial direction because the pressure is only applied from the upper part on the ordinary one-way press. Compared with the powder column pressed and formed on the two-way press, the molding density is low and the axial uniformity is poor.

Abstract
The invention discloses an explosive-shaped powder bidirectional pressing device which is mainly composed of a punch, a die retreating cylinder, a compression spring, a die cylinder, a base and a bottom cylinder. The pressing process is safe, reliable, convenient and fast, the function of bidirectional pressing is achieved on a unidirectional die pressing machine, and the problem that the axial density of explosive pillars is not evenly distributed in the explosive-shaped powder pressing process of the unidirectional die pressing machine is solved. The explosive pillars pressed through the explosive-shaped powder bidirectional pressing device are complete in shape and even in density. The explosive-shaped powder bidirectional pressing device is suitable for the explosive die pressing technology.
Description
technical field [0001] The invention relates to a two-way pressing device for explosive molding powder, which is suitable for molding and pressing technology of explosive molding powder. Background technique [0002] Explosive molding powder is used to fill ammunition after being pressed into shape by a molding machine. The existing compression molding device has uneven density in the axial direction because the pressure is only applied from the upper part on the ordinary one-way press. Compared with the powder column pressed and formed on the two-way press, the molding density is low and the axial uniformity is poor. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-way pressing device for explosive molding powder, which can improve the molding density and axial density uniformity of explosives, and realize the function of two-way pressing on ordinary one-way presses. [0004] In order to solve the above...
