Metallic Bellow Forming Machine

• The machine has a hydraulic cylinder, which will open and close the bellow die. The bellow die expands to form the bellow. The actual bellow blank is a stainless steel sheet metal seam welded in cylindrical shape.
• It rests on a rotary indexing table, which in turn, is mounted on a vertical indexing slide. This indexing slide is driven by a servo motor connected to a ball screw. The sliding surfaces are made of LM guides and blocks for smooth and fast indexing.
• The servo motor, hydraulic expansion and indexing table rotation is seamlessly integrated with a PLC for complete auto-cycle function. 
• A 7? touch screen HMI is provided, so that parameters such as bellow pitch, number of rotations and angle of rotation per expansion, speed of indexing, etc can be easily entered and set.
• A fixture is mounted on a vertical slide, driven by a ball screw and servo motor, which can accurately control the position and pitch of the bellow. On this carriage of the vertical slide, a fixture is mounted which can hold the job and rotate it. The rotation of the fixture is motorized and is integrated into the PLC auto-cycle.  At the center of the fixture, a die is mounted with a hydraulic press. This die has a wedge type arrangement to open and close. PLC programmed auto-cycle will be provided for the machine.
• The PLC enabled auto-cycle ensures bellow forming process automatic from one pitch to the next and so on, without human intervention.
