Problems solved by technology

[0004] The present invention solves the problem that copper and steel are two different metals prepared by the existing method. The physical and chemical properties are quite different, and the welding difficulty is high. It needs to consume a lot of electric energy, and the arc still has the problem of radiation pollution, and a method of ultrasonic vibration-assisted self-propagation to prepare copper elastic tape is proposed

specific Embodiment approach 1

[0018] Specific implementation mode one: combine figure 1 Describe this implementation mode, this implementation mode is realized through the following steps:

[0019] Step 1: Set the annular cylindrical graphite crucible 2 on the outer diameter position A of the copper shell 1, and seal the gap between the annular cylindrical graphite crucible 2 and the copper shell 1 with yellow mud to ensure the accuracy and safety of the belt production ;

[0020] Step 2: Connect the ultrasonic generator 3 with the ultrasonic introduction device 4, and fix the tool head 5 on the ultrasonic introduction device 4 on the ring-shaped graphite crucible 2, so as to ensure good connection between each device;

[0021] Step 3: uniformly mixing aluminum powder and copper oxide powder to obtain the thermite reactant 6, and putting the thermite reactant 6 into the annular cylindrical graphite crucible 2;

[0022] Step 4: Turn on the ultrasonic generator 3 and the ultrasonic introduction device 4, t...

specific Embodiment approach 2

[0025] Specific implementation mode two: combination figure 1 Illustrate present embodiment, present embodiment is that the inner diameter of the annular cylindrical graphite crucible 2 in the step 1 is determined according to copper shell 1 diameter, and the diameter of copper shell 1 is bigger, and the diameter of copper bullet belt is bigger, and required aluminum powder and The more copper oxide powder there is, the higher the height of the annular cylindrical graphite crucible 2 is. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0026] Specific implementation mode three: combination figure 1 This embodiment is described. In this embodiment, the tool head 5 that transmits ultrasonic vibration in step 2 is fixed at the central position of the height of the annular cylindrical graphite crucible 2 . Other steps are the same as in the first embodiment.

Abstract

The method discloses a method for preparing a copper cartridge belt in a self-propagating manner with the assistance of supersonic vibration. The method is used for solving the problems that according to a copper cartridge belt prepared in an existing method, a large amount of electric energy needs to be consumed in the surfacing process, and radiation pollution exists in electric arcs. The method comprises the steps that firstly, a clearance between a ring-pillar-shaped graphite crucible and a copper cartridge is sealed with yellow mud; secondly, an ultrasonic generator and ultrasonic guide-in equipment are connected, and a tool head on the ultrasonic guide-in equipment is fixed to the ring-pillar-shaped graphite crucible; thirdly, a thermit reactant is put into the ring-pillar-shaped graphite crucible; fourthly, the ultrasonic generator and the ultrasonic guide-in equipment are started; fifthly, gunpowder is evenly laid on the upper surface of the thermit reactant and ignited, a thermit reaction happens, and the thermit reactant and a copper cartridge matrix fully generate a metallurgy reaction; and sixthly, after the thermit reaction is finished, the ultrasonic generator and the ultrasonic guide-in equipment are stopped, cooling is carried out, and after the ring-pillar-shaped graphite crucible is unloaded, molten copper is deposited on the surface of the copper cartridge to form the copper cartridge belt. The method is used for preparing the cartridge belt.

Description

technical field [0001] The invention relates to a method for preparing elastic belts in the shell manufacturing process, in particular to a method for preparing copper elastic belts by self-propagation assisted by ultrasonic vibration. Background technique [0002] Belts play a vital role in all types of shells. During the firing process of the shell, the belt is pressed into the rifling, sealing the gunpowder gas, and making the shell rotate under the action of the rifling, thereby improving the range and accuracy of the shell. The metals used as shell belts are mostly copper alloys and soft iron, and copper belts are relatively more widely used. The currently used methods of producing elastic belts mainly include mechanical fitting and surfacing. The mechanical fitting method is to fit the copper alloy or soft iron belt to the projectile body under strong pressure by processing a guide belt groove on the projectile body (the large-caliber projectile is a dovetail groove)...
