The present invention relates to a method of manufacturing a frame of a greenhouse for cultivating an indoor crop, and more particularly, to a method of manufacturing a frame of a greenhouse for cultivating indoor crops, comprising: setting a bending position of a left side bending face 10 in a longitudinal direction of a pipe 100 as an object Bending (S110) the left bending face 10 of the pipe 100 by rounding it at a predetermined angle A step S120 of transferring the pipe 100 to the left Stopping the center bending surface 30 of the pipe 100 at the bending position in step S110 Bending (S140) rounding the center bending face 30 of the pipe 100 at a predetermined angle A step S150 of transferring the pipe 100 in a left direction Stopping the right bending surface 20 of the pipe 100 at the right bending position (S160) Bending the right bending surface 20 of the pipe 100 by a predetermined angle (S170) The present invention provides a method for manufacturing a frame of a vinyl house for indoor crop cultivation.The present invention provides a method for manufacturing a frame for forming a greenhouse for cultivating an indoor crop, which provides a method of automatically bending an object pipe to produce a frame for a vinyl house, And to provide a basis for designing the device.In addition, since several hundred frames are required to complete one greenhouse, a frame is manufactured by using a manufacturing method which saves time for this and has a high efficiency of mass production per unit time, thereby reducing cost and cost will be.In addition, it is manufactured to have an accurate symmetry for the left bending surface, the center bending surface, and the right bending surface of the frame for a greenhouse having symmetry, thereby improving the quality.본 발명은 실내 작물 재배용 비닐하우스의 프레임 제조방법에 관한 것으로서, 보다 상세하게는, 대상물인 파이프(100)길이방향으로 좌측벤딩면(10)의 벤딩 위치를 설정하는 단계(S100) 파이프(100)의 좌측벤딩면(10)을 설정된 각도로 라운딩시켜 벤딩하는 단계(S110) 상기 파이프(100)를 좌측방향으로 이송하는 단계(S120) 파이프(100)의 정중앙 벤딩면(30)을
