Automatic pressing production line of large explosive column

Abstract

The invention relates to an automatic pressing production line of a large explosive column. The automatic pressing production line comprises a hydraulic press, which is composed of an upper beam, an upper return cylinder, an upper slide block with a cylinder, an upper punch, a middle girder with a die sleeve, and a lower beam. The automatic pressing production line is characterized by also comprising an automatic weighing and feeding device, a powder smoothing device and an automatic discharge device, which are arranged at the periphery of the hydraulic press; a lower return cylinder is arranged at the upper part of the lower beam; the lower return cylinder is connected with a lower slide block with a cylinder; a lower punch is arranged on the lower slide block with the cylinder; an automatic evacuating device is arranged at the lower part of the upper slide block with the cylinder; and mechanical limiting devices are arranged on the upper slide block with the cylinder and the lower slide block with the cylinder. The automatic pressing production line has the advantages that full-automatic operation of feeding, smoothing, two-way control and discharge of the explosive column can be achieved through the production line; the labor intensity of operating personnel can be greatly reduced; the production efficiency of a large-tonnage hydraulic press is improved; potential safety hazards are avoided; air bubbles of the explosive column in the pressing process can be reduced; the compact evenness and the accuracy of the explosive column are improved; and the product quality is also ensured.

Description

technical field [0001] The invention relates to the technical field of powder pressing hydraulic machinery manufacturing, in particular to an automatic pressing production line for large explosive powder columns. Background technique [0002] At present, with the rapid development of my country's military industry, more and more large-tonnage precision numerical control two-way hydraulic presses are used in the production process of explosive grains. Put it in the mold. In the known technology, the hydraulic press for pressing the explosive column mostly adopts manual feeding, which is inefficient and has potential safety hazards. After the powders of different components are put into the mold by manual feeding, the powders in the mold need to be fully stirred and smoothed. The mixing and blending of powder in traditional hydraulic presses is done manually. The aforementioned manual operations are not only labor-intensive and inefficient, but also cause harm to human health...

AI Technical Summary

Problems solved by technology

The above-mentioned vacuum device cannot realize the automatic vacuuming of the explosive column when it is extruded to different heights, not only it is difficult to ensure the vacuum degree of the workpiece in the closed cavity of the mold, but also it cannot meet the needs of the fully automatic explosive column production line
