Problems solved by technology

[0005] To sum up, the improvement of mechanical processing equipment for energetic materials and the application of new technologies are difficult to popularize to varying degrees. The main reasons are: 1) The severe test of processing safety on new technical equipment and processing technology ; 2) The contradiction between the reliability of the modified equipment and the optimized process flow to achieve high-quality processing; 3) The cutting and dissecting process chains currently mature and applied are lengthy, and the development or transformation of intrinsically safe special processing equipment is relatively expensive. Process implementation cycle is long

Abstract

The invention discloses a rolling cutting self-lubricating cutting tool suitable for machining of an energetic material. The cutting tool includes a hobbing cutter rod, one end of the hobbing cutter rod is provided with a positioning hole, the positioning hole is internally provided with a hobbing cutter head, one side of the hobbing cutter rod is provided with a pipe joint, the hobbing cutter rod is internally provided with a cutting fluid pipeline, one end of the cutting fluid pipeline is communicated with the pipe joint, and the other end of the cutting fluid pipeline is communicated with the hobbing cutter head. Based on the coordinated application of an existing mature energetic material mechanical machining technology and current processing equipment, minimum quantity lubrication and hobbing are introduced, and high-quality surface machining of PBX composite explosive parts is more convenient to achieve.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of energetic materials, in particular to a hobbing self-lubricating tool suitable for mechanical processing of energetic materials. Background technique [0002] High-energy explosives PBX (Polymer Bonded Explosives, polymer bonded explosives) is an energetic material with excellent comprehensive performance. It is one of the core materials in the weapon equipment system in various weapon systems. Due to its low stiffness and strength, large coefficient of thermal expansion, and certain viscoelasticity, this material is a very special composite material with heterogeneous macroscopic isotropy and microscopic anisotropy, and its processing characteristics are soft, The complex characteristics of stickiness, brittleness and elasticity affect the processing quality and production safety of products to a certain extent. [0003] In view of the particularity of the processing of energet...
