Abstract

The invention relates to a production method for compression molding of PBX (Polymer Bonded Explosive) by using ultrasonic pressing. The production method comprises the following steps: a, feeding powder PBX (10) into a PBX forming device, starting a pressurizing device on the PBX forming device to enable the PBX (10) to be positioned in a pressed state; when a pressure value applied to the PBX (10) exceeds a set pressure value, starting ultrasonic transducers and ultrasonic generators; using ultrasonic waves generated by the ultrasonic transducers to act on a PBX powder body (10) to generate vibration; gradually increasing the pressure value applied to the PBX (10) until the PBX (10) is completely compressed. The production method disclosed by the invention has the technical effects that the density, the strength and the uniformity of the PBX obtained by compression molding are improved, the quality of a finished product of the PBX is effectively improved, and the energy effect of the PBX is improved.

Description

technical field [0001] The invention relates to a method for forming PBX explosives, in particular to a method for making PBX explosives by pressing and forming ultrasonic waves. Background technique [0002] PBX is a kind of mixture composed of high-energy explosive crystals, binders and desensitizing agents. Due to its excellent explosive performance and mechanical properties, PBX has been widely used in military and industry. It is used to manufacture Various warhead charges, rocket propellants, explosive molding, mining, oil perforating bullets, etc. In the molding process of PBX drug parts, compression molding is one of the most commonly used methods. Because there are many kinds of materials in PBX, and the content and performance parameters of various materials are quite different, and the content of binder is low, so it is impossible to completely cover the explosive crystal grains and fill the pores between the grains. At the same time, due to the friction between...
