Firing device for primer performance test

Abstract

The invention relates to a firing device for a primer performance test, which comprises a firing device support, a firing device sleeve, a firing pin part, a firing device end cover, a toggle wrench and a firing wrench. The firing device is characterized in that: the firing device support is arranged on a base of a primer performance testing system through a guide rail, and is provided with a spiral adjusting mechanism which regulates the position of the firing device support so as to regulate the gap of the end part of a firing pin relative to the end face of primer; the firing device sleeve is in detachable connection to the firing device support, and can be replaced by a firing device sleeve made of an insulating material; a through hole is formed on the firing device end cover which is matched with the firing device sleeve made of the insulating material; a copper firing pin is arranged in the firing device sleeve made of the insulating material; and one end of the copper firing pin is connected with one electric firing lead wire, and the other electric firing lead wire is connected with the primer to form an electric firing loop. By adopting the firing device, specified standard firing energy is provided for percussive primer, and the firing device can form a firing loop with the electric primer to meet the firing requirement on electric primer, so that the universal requirement on the primer performance firing device can be fulfilled.

Description

technical field [0001] The invention relates to a firing device for a primer performance test, which belongs to a firing device for a pyrotechnic product ignition performance test, in particular, it can not only meet the firing energy specified for firing various percussive primers, but also can form an ignition circuit with an electric primer to meet the requirements of an electric primer. Primer ignition requirements. Background technique [0002] The firing device is a mechanical device that the firing pin can produce a firing action and has a specified firing energy. The trigger is an important part of the primer performance testing system. There are two functions: (1). According to the prescribed standard percussion energy, it acts on the tested primer, and evaluates the ignition reliability of the primer; (2). Provides standards for the next step of the primer output energy test and action reliability test. Input energy is the basis for the start-up of the whole test...
