Casting process for high-explosive primer

Abstract

The invention discloses a casting process for a high-explosive primer. The casting process comprises the following steps of: firstly, manufacturing shells of the primer, and mixing and heating to melt solid explosive raw materials in a melting tank; installing a mold provided with the shells onto a tooling plate on a triple-speed chain, moving the shells to reach a primary explosive injection station, and automatically metering by a first explosive injection tank to inject a high-energy composite explosive into the cavity of an inner shell; after explosive injection is completed, driving the shells to move forwards by the triple-speed chain, and cooling the high-energy composite explosive in the inner shell; moving the shells to reach a secondary explosive injection station, and then, automatically metering by a second explosive injection tank to inject a conventional composite explosive into the cavity of an outer shell to complete explosive injection for the second time; driving the shells to move forwards by the triple-speed chain, and cooling the conventional composite explosive in the outer shell; enabling the shells to enter a mold retreating station to complete a mold retreating operation; and solidifying to shape the liquid explosive, and then, entering a packaging process to form a finished product. The casting process for the high-explosive primer is simple, can be easily operated and is low in production cost, and automatic and continuous production is realized.

Description

technical field

[0001] The invention belongs to the technical field of civil blasting equipment production, and in particular relates to a high-explosive detonator injection process method. Background technique

[0002] Initiators are blasting equipment used to detonate insensitive explosives or chamber blasts, and belong to relay blasting equipment. The existing production methods of detonators all adopt the step-by-step injection method. First, make a special mold and a paper tube shell. In the paper tube, after the liquid medicine is solidified and formed, the mold is knocked out with a wooden hammer to release the mold, and finally enters the packaging process to form a finished product. The whole production process is manually operated, the process is cumbersome, the labor intensity is high, the risk is high, the production efficiency is low, the cost is high, the uncertain factors caused by human operation have a great influence, and the product quality cannot be guar...
