the selected steel plate is continuously stretched twice, the stretched bottle mouth is cut flat, the stretching is continuously performed twice again, the stretched bottle mouth is cut flat again,
then the micro gas storage bottle after twice cutting is subjected to high-frequency annealing, oxide skin is cut off, the mouth is reduced, the micro gas storage bottle after the mouth is reduced is subjected to third cutting and flattening,
drilling a chamfer on the micro gas storage bottle which is cut flat for the third time, rolling threads on the outer side of the neck of the micro gas storage bottle, ultrasonically cleaning, filling,
monitoring the filled gas storage bottle, trimming, cutting, externally processing and detecting negative pressure to obtain the required miniature gas storage bottle;
the filling adopts a special inflation valve head, the miniature gas cylinder body is clamped into the inflation valve head device, and the miniature gas cylinder is inflated and synchronously packaged under pressure during the operation of the inflation valve head device.
Further, the selected steel plate is cut into round pieces.
Furthermore, a common hydraulic drawing machine is adopted for drawing the steel plate.
Furthermore, the bottle mouth adopts the instrument vehicle to cut the possible ripple mouth of bottle mouth flat, prevents that the bottle mouth from forming the breach.
Further, the chamfering and drilling integrated machine for the miniature gas storage cylinder is adopted to ensure that gas can enter the cylinder more smoothly.
Compared with the prior art, the invention has the beneficial effects that: the invention adopts the special inflation valve head to carry out pressure sealing, does not need to solidify and encapsulate carbon dioxide, improves the sealing efficiency of the miniature gas cylinder, reduces the waste of time and is convenient for production and life.
