It consists of a drawing machine that performs drawing from the outside to a position below the flange of the work held at the ascending position, and the drawing machine is integrated with the head at the lower end of the rotating shaft vertically supported by the fixed support. A squeezing roller is rotatably mounted on a movable base fixed to rotate and mounted on the lower surface of the head so as to be movable in a radial direction, and is externally fitted on the rotary shaft so as to be movable in an axial direction. The inserted elevating cylinder and a driving device attached to a fixed support for imparting vertical movement to the elevating cylinder are coupled in the up and down direction while allowing the rotation of the elevating cylinder, and the base is pivoted to the head. Raise one end of L-shaped arm The other end is locked to the cylinder by locking it to the cylinder, and the swing roller of the L-shaped arm due to the vertical movement of the lifting cylinder moves the diaphragm roller of the movable table toward and away from the rotation axis of the head. This is the structure adopted.
