Abstract
The manufacturing method on a kind of rigid fuzing gun powder includes the following steps: preshoot the metal strip; shoot the metal strip out of the location hole and dump in plastic strips; finish shooting the metal strip; shoot the plastic block and two electrodes and joint the igniter wire with the electrodes; mix them; produce the material of gun powder; stain the powder, including dipping the powder and drying alternately; cover lagging; sort the values of the resistance and dry it finally. The invention mostly is carried out by the machine automatically, eliminates the effect of manual operation and improves not only the consistency of products' performance indexs but also the production efficiency greatly. The step of staining the powder alternates with the drying for several times, which makes the quantity of the powder dipped every time almost same. The drying is carried out completely. The quality of the powder is increased remarkably. The work of winkling the lagging and resistance of the powder also increases the stability and consistency of the powder, makes the powder featured by good consistency, antistatic, anti stray-current and adaptation to high precision blast.
