         8 . The forming system according to  claim 6 ,
 wherein the forming device further includes a drive mechanism that moves at least one of the lower die and the upper die.   
     
     
         9 . The forming system according to  claim 8 ,
 wherein the drive mechanism includes
 a slide that moves the upper die so that the lower die and the upper die are joined together, 
 a pull-back cylinder as an actuator that generates a force for pulling the slide upward, 
 a main cylinder as a drive source that downward-pressurizes the slide, and 
 a drive source that applies a driving force to the main cylinder. 
   
     
     
         10 . The forming system according to  claim 6 ,
 wherein the forming device further includes a holding unit that holds the metal pipe material disposed between the lower die and the upper die.   
     
     
         11 . The forming system according to  claim 10 ,
 wherein the holding unit includes a lower electrode and an upper electrode that interpose vicinities of end portions of the metal pipe material from an up-down direction.   
     
     
         12 . The forming system according to  claim 6 ,
 wherein the forming device further includes a heating unit that heats the metal pipe material by energizing the metal pipe material.   
     
     
         13 . The forming system according to  claim 12 ,
 wherein the heating unit heats the metal pipe material in a state in which the metal pipe material is separated from the lower die and the upper die, between the lower die and the upper die.   
     
     
         14 . The forming system according to  claim 6 ,
 wherein the forming device further includes a cooling unit that cools the forming die.
