Method for manufacturing pressure container having opposite dome ends with different opening diameters |
摘要 |
A method for manufacturing a pressure container having opposite dome ends with different opening diameters, comprising double-stepped windings involving a primary winding carried out at a small winding angle in a polar winding manner, for forming a primary form on a mandrel provided with bosses having different diameters and a secondary winding carried out at a large winding angle in a helical winding manner, for forming a secondary form on the primary form. The polar winding is carried out under the condition that a metal inserter having a diameter similar to that of the smaller boss is mounted to the larger boss, to be protruded axially outwardly of the larger boss. The helical winding is carried out under the condition that an inserter having a diameter similar to that of the larger boss is mounted to the smaller boss, to be protruded axially outwardly of the smaller boss |
