Multi-grain one-time forming device and multi-grain one-time forming method

Abstract

The invention discloses a multi-grain one-time forming device and a multi-grain one-time forming method. The device comprises an upper workbench and a lower workbench, a plurality of sets of explosivepressing dies are positioned on a lower base plate; a positioning device for positioning the explosive pressing dies is arranged on the top surface of the lower base plate; the lower base plate is installed on the lower workbench through screws, the positioning device is a positioning screw, a plurality of threaded holes used for installing the positioning screw are formed in the lower base plate, a positioning groove is formed in the bottom of each explosive pressing die, and a nut of the positioning screw can be arranged in the positioning groove to limit the position of the corresponding explosive pressing die. The method is simple and convenient, the production efficiency is high, the productivity of a single device can be fully utilized, a plurality of grains are formed through one-time pressing, the forming efficiency is high, the rejection rate is low, and meanwhile the problem that the pressure borne by the plurality of explosive pressing dies which are horizontally arranged in parallel is different due to parallelism errors of the upper workbench and the lower workbench is solved.

Description

technical field [0001] The invention relates to a device and a method for one-time molding of multi-powder columns. Background technique [0002] The powder pressing mold is an important process equipment for pressing and forming explosive grains, and the density and size of the grains are important indicators of the quality of the grains. The parallelism of the upper and lower worktables of the pressing equipment sometimes has a large error, which makes the production capacity of the pressing equipment excessive. Parallel pressing multiple sets of molds will cause slight differences in the pressure on different molds. Coupled with the differences between different molds, it is difficult to ensure uniform density of the grain The consistency of sex and size is easy to produce waste products. In view of this situation, usually only a single device can be used to form only one grain at a time, which leads to waste of production capacity and low production efficiency. Conten...
