Description
Technical Field
The invention relates to a gas cylinder, in particular to a reducing cylinder body of the gas cylinder.
Background
Gas cylinders are commonly used for filling with a pressure medium and generally comprise an upper half body and a lower half body welded together. The upper and lower half-bottles are generally made by punching a steel plate into a circular piece with a die and then drawing the circular piece into an open structure with the die. The thickness of the half bottle body at the arc transition section close to the closed end becomes thinner due to drawing, and the thickness of the half bottle body close to the open end becomes thicker due to drawing. After welding of the upper half bottle body and the lower half bottle body of the gas cylinder is completed, the gas cylinder still needs to be filled with a filling test, and because the arc transition sections at the upper end and the lower end of the gas cylinder are thinned by drawing, the internal pressure born by the gas cylinder at last can be reduced, and the use safety of the gas cylinder is lowered. And the stretching manufacture of the bottle body has certain requirements on the performance of steel, and the cost of the steel is higher.
