Definitions
- the method for manufacturing a body of a cartridge case with the process of cold forming of seamed or seamless pipes is first based on the formation of the specific shape of the pipe B.
- a passage A from the larger diameter of the pipe B to a smaller diameter is produced by means of a first-stage tool 1.
- a second-stage tool 2 and a pin 3 are used to produce the final shape of the passage A at one end of the pipe B.
- a further tool 4 and a pin 5 are used to deform the basic shape of the pipe b into a cone shape, wherein a pin 6 is used to calibrate the opening at the passage A of the pipe B.
- both final openings are levelled by means of turning.
