The present invention provides a pouch forming device. The pouch forming device comprises a die member including a die on which a pouch film is disposed on a top surface thereof, in which a forming part is formed, and a die holder to which the die is fixed, a stripper member that presses and fixes the pouch film disposed on the die when descending and a first driving piece to move the stripper vertically, a punch member including a punch plate comprising a punch configured to be inserted into the forming part to form an electrode assembly accommodation part in the pouch film and a second driving piece to move the punch plate vertically, and a control member that controls the first driving piece to allow the stripper to ascend when the punch is inserted into the forming part to decrease a pressing force applied to the pouch film. 본 발명은 파우치 성형장치로서, 성형부가 형성된 상면에 파우치필름이 배치되는 다이와, 상기 다이가 고정되는 다이홀더로 마련된 다이부재; 상기 다이에 배치된 상기 파우치필름이 고정되게 가압하는 스트리퍼와, 상기 스트리퍼를 상하방향으로 이동시키는 제1 구동편으로 마련된 스트리퍼부재; 상기 성형부에 삽입되면서 상기 파우치필름에 전극조립체 수용부를 성형하는 펀치를 구비한 펀치플레이트와, 상기 펀치플레이트를 상하방향으로 이동시키는 제2 구동편으로 마련된 펀치부재; 및 상기 펀치가 상기 성형부에 삽입되면서 상기 파우치필름을 가압하면, 상기 제1 구동편을 제어하여 상기 스트리퍼를 상승시킴에 따라 파우치필름의 가압력을 감소시키는 제어부재를 포함한다.
