(57) Abstract:

Usage: metal forming and can be used in pipe manufacture in the manufacture of cylinders. The inventive method includes the cutting of the pipe-to-length harvesting, cleaning the inner surface, coating the entire inner surface of stekloemali and alternate sealing the ends of the workpiece to pre-heat. Coating of the inner surface of the workpiece by stekloemali carried out after closing one end of the workpiece.

The invention relates to the field of metal forming and can be used in pipe manufacture in the manufacture of cylinders.

A known way to get pieces of cylinders in the ed. mon. USSR N 1754298, class B 21 D 22/16, 1992 [1] the prototype.

Method [1] is that after cutting the pipes on the balloon preform to produce cleaning of the internal surface of tubular blanks, put the glass coating on the inner surface of the tubular workpiece. After successive heating of the ends of the workpiece to produce the sealing of the bottom and neckline, and after closing the neckline additionally perform the calibration hole of the neck of the container I increase the strength of the container.

A method of manufacturing a cylinder is as follows.

After cutting the pipes on the balloon preform, they come to sunset machines. Originally balloon on the workpiece roll the bottom of the tank. After the seaming heads make cleaning the inner surface of the obtained glass from scale and rust. Cleaned the glass comes to the area of the coating where the internal surface applied glass floor. After applying the glass coating glass is fed to the rolling machine for seaming the neckline. Before sealing cap produce heating of the end of the glass on the length equal to the diameter of the pipe. After closing of the neck of the container is fed to the heat treatment and machining of the neck.

An example of a specific implementation.

Consider a manufacturer of automotive cylinder intended for transportation and storage of compressed gas. As the workpiece is used, the pipe diameter 219 mm, a wall thickness of 6.5 mm and a length of 12 m pipe Material

steel HM.

The pipe is cut on the balloon preform length 1750 mm Initially roll the bottom of the tank, and then make cleaning the inner surface of the obtained stack is, activat the neck of the container, produce a heat treated cylinder and mechanical treatment of the neck.

A method of manufacturing a container comprising cutting the pipe-to-length harvesting, cleaning their inner surface, coating the inner surface of stekloemali and alternate sealing the ends of the workpiece to pre-heat, characterized in that the coating of the inner surface of the workpiece stekloemali carried out after closing one end of the workpiece.

FIELD: plastic working of metals, namely manufacture of high-pressure bottles.

SUBSTANCE: method comprises steps of forming shell; swaging at least one open end of shell; forming bottom and mouth while making at least two mutually joined cone surfaces and increasing central angle from shell to mouth; at least after one swaging operation performing heat treatment of swaged end of shell. High-pressure bottle includes shell and two bottoms. One bottom has mouth for placing locking means. Bottom and mouth are made as one piece. Bottom from shell until mouth is in the form at least of two joined lateral surfaces of circular regular truncated cones. Each such joint is performed due to joining lateral surfaces of truncated cones along lines of bases of their small and large diameters respectively. Said joints may be smooth, with radius transitions.

EFFECT: simplified design of bottle, enhanced technological effectiveness of making it.
