Firework grain automatic pressing and shaping device

Abstract

The invention discloses a firework grain automatic pressing and shaping device which comprises an upper base plate connected with an upper oil press. Multiple pressing columns are arranged on the upper base plate in a matrix manner; the firework grain automatic pressing and shaping device further comprises a lower base plate fixed on the rack; the lower base plate is provided with a plastic isolation buffer layer; a powder charging plate is arranged between the upper base plate and the lower base plate; multiple powder charging holes in matrix arrangement are formed in the powder charging plate; the pressing columns and the powder charging holes are arranged correspondingly; the powder charging plate is connected with the lower oil press sequentially through the connecting rod and a thrust plate. According to the firework grain automatic pressing and shaping device, an upward ejecting column is cancelled, equipment is simplified, manufacturing cost is reduced, each pressing time is shortened, and production efficiency is increased; due to the arrangement of the plastic isolation buffer layer, direct contact and pressure applying effect between the gunpowder and metal is reduced, and safety and corrosion resistance of the equipment is improved in comparison with original equipment; meanwhile, as a pressure-bearing surface with certain softness, improvement of the pressing quality of the shaped grain is benefited; the shaped grain drops automatically onto a material receiving tray rather than being swept manually, so that personal safety is ensured.

Description

technical field [0001] The invention relates to a device for automatically completing the compression molding of fireworks powder columns. Background technique [0002] In the production of fireworks shells, combined fireworks, etc., some gunpowder drugs need to be pressed into a generally cylindrical powder column by a hydraulic press. The equipment that completes this work is called a press machine, and the industry is also directly referred to as a hydraulic press. The structure of existing medicine pressing machine sees figure 1 , including an upper base plate 1 connected to a driving mechanism such as an upper oil press 10, and a plurality of lower pressing columns 2 arranged in a matrix on the upper base plate 1; a lower base plate 3 fixed on the frame is also included, and a plurality of upper ejecting columns 4 are arranged in a matrix on the lower base plate 3 The lower pressure column 2 and the upper top column 4 are arranged correspondingly, and a medicine-loadin...

AI Technical Summary

Problems solved by technology

[0004] The defect of the existing equipment is that during the forming process of the powder column in the charging hole 6, the lower pressure column 2 and the upper top column 4 made of metal are in direct contact with the gunpowder to apply pressure, which affects the safety of the equipment and the corrosion resistance of the machine parts. Cause adverse effects; production efficiency needs to be improved; at the same time, it is necessary to manually collect the pressed powder column, and the cutting work is highly dangerous
