Integrated vortex cooling tool suitable for mechanical processing of energetic materials

Abstract

The invention discloses an integrated vortex cooling tool suitable for mechanical processing of energetic materials. The integrated vortex cooling tool comprises a diamond blade, the base center of the diamond blade is provided with a standard pressing positioning hole, a pressing screw is installed in the positioning hole, the diamond blade is assembled on a cutter head through the pressing screw, a cold air flow and cutting fluid cross passage is arranged inside the cutter head, the passage intersection is sealed through a sealing screw to form a cutting fluid atomization chamber, the end ofthe cutter head is provided with a thread to be connected with the cold air end of a vortex pipe, the vortex pipe communicates with an external compressed gas source through a pipe joint, and a clampbase is internally provided with a cutting liquid heat conduction and flow regulating passage. Based on an existing mature mechanical processing technology of the energetic material, current generalprocessing equipment is used in cooperation, a micro-lubrication and temperature-controlled cutting processing method is introduced, surface high-quality processing of PBX composite explosive parts isfacilitated, and meanwhile, the effective inhibitory effect is achieved on the problems of product cutting heating, discharging, impact stability losing and the like.

Description

technical field [0001] The invention relates to the technical field of machining of energetic materials, in particular to an integrated eddy current cooling tool suitable for machining of energetic materials. Background technique [0002] High-energy explosives PBX (Polymer Bonded Explosives, polymer bonded explosives) is an energetic material with excellent comprehensive performance. As the core functional component material of various important warheads, it is widely used in land, sea, air and Second Artillery. class weapon system. With the rapid development of weapons and equipment systems, the demand for precision machining of various energetic material components is also increasing day by day, and the safety of machining has always been the key to restricting the development of its technology. In addition, due to its low stiffness and strength, large coefficient of thermal expansion, and certain viscoelasticity, this material is a very special composite material with h...

Problems solved by technology

[0005] Therefore, the prior art and invention reports still have the following deficiencies in solving the problems in the machining of energetic materials: 1) The spray cooling device is complex, the atomized cutting fluid is single, and the spray atomization temperature is difficult to adjust; 2) The integration of the cooling and lubrication system Low, the tool is separated from the spray cooling device, and the system reliability is low; 3) The eddy current cooling technology is limited to the use of cold air drainage, and does not consider the problem of temperature range control
