In order to solve the problem of the necessity of dismantling and destroying the small-caliber ammunition in the test environment, a portable small-caliber ammunition drawing machine was designed to solve the problem that the existing test conditions could not meet the situation of drawing ammunition on site. The bullet pulling machine adopts a vertical structure and uses a separate hydraulic Jack to provide the driving force for bullet pulling, which not only ensures the rhythm of bullet pulling, but also reduces the volume of the equipment. The results show that the design can realize the stability and controllability of the small-caliber ammunition pulling process, which is easy to carry and operate, and improves the safety of pulling ammunition, and has a certain promotion value.
