APPARATUS FOR CORRECTING SHAPE OF COIL

An apparatus to correct a coil shape is disclosed. The apparatus to correct the coil shape comprises: a shaft part inserted into a hollow part of a wound coil wherein a diameter of the shaft part can be expanded to make a contact with an inner wound part of the wound coil; a magnetic force part connected with the shaft part, generating a magnetic force; and a shaft rotating part rotating the shaft part in a state where the shaft rotating part makes close contact with the inner wound part. The apparatus to correct the coil shape may correct a loosen coil shape which is loosely wound to be more compactly shaped; thereby a deflection and deformation caused by the loosen shape of the wound coil may be prevented. Moreover, the poor shape of the rolled material, which is caused by the deflection and deformation of the wound coil, may be prevented. 코일 형상 교정장치에 대한 발명이 개시된다. 본 발명의 코일 형상 교정장치는: 권취코일의 중공부에 끼워지고, 권취코일의 내권부와 접하도록 직경이 확장가능한 샤프트부와, 샤프트부와 연결되고, 자력을 형성하는 자성부와, 샤프트부가 내권부에 밀착된 상태에서 샤프트부를 회전시키는 샤프트회전부를 포함하는 것을 특징으로 한다.
