Bottomed tubular body processing device

A bottomed tubular body processing device that performs necking on an opening end of a bottomed tubular body a plurality of times while conveying the bottomed tubular body along a conveyance path, the bottomed tubular body processing device comprising:

• a multi-stage necking section in which a plurality of necking units are sequentially disposed along the conveyance path;
• and
• a circulating conveyor configured to refeed, to an upstream necking unit provided upstream in the multi-stage necking section, the bottomed tubular body discharged from a downstream necking unit provided downstream in the multi-stage necking section,
• the circulating conveyor having a conveying surface which is disposed to face the opening end of the bottomed tubular body, and being configured to convey the bottomed tubular body by retaining the opening end of the bottomed tubular body against the conveying surface,
• the necking units each including a processing turret that performs the necking on the bottomed tubular body,
• the processing turret including:
• a bottom turret provided with a plurality of pockets disposed in a circumferential direction and configured to hold the bottomed tubular body in the pockets and support a bottom portion of the bottomed tubular body;
• and
• a tool turret disposed on one side in an axial direction of the processing turret and including a processing tool that performs the necking on the bottomed tubular body,
• the bottom turret being configured to be movable in an axial direction by a position adjustment mechanism, based on a height in a tube axial direction of the bottomed tubular body to be subjected to the necking.
