Device and method for manufacturing profile combination

A nesting device for manufacturing a profile combination, the nesting device comprising:

• a) a nesting bed (61);
• b) a nesting base (62);
• and
• c) a rotating positioning device, the rotating positioning device comprising a saddle (63), a first gas cylinder (T1), two steady rests (64), and two rotators (65);
• wherein
• the nesting bed (61) is fixed on the ground (9);
• the nesting base (62) is disposed and is horizontally movable on the nesting bed (61);
• the saddle (63) is disposed and is horizontally movable on the nesting base (62);
• the saddle (63) is connected to the first gas cylinder (T1), and the first gas cylinder (T1) drives the rotating positioning device to move on the nesting base (62);
• the two steady rests (64) are oppositely fixed on the saddle (63) at a certain interval;
• the rotator (65) is arranged inside each steady rest (64) and is rotatable in relation to the steady rest (64);
• each rotator (65) comprises:
• a square hole (652), and a plurality of clamps;
• the square hole (652) passes through the rotator (65) in a direction of a length of the rotator (65) and matches with a profile (B);
• the clamps are arranged on an end face of the rotator surrounding the square hole (652);
• and
• each clamp comprises:
• a guide rail (66), and a chuck (67);
• the guide rail (66) is fixed on the end face of the rotator (65), and the chuck (67) is movable on the guide rail (66) and leans against a first profile member.
