Method and system for manufacturing nested profile combination

A system for manufacturing a nested profile combination in accordance with a method, the method comprising the following steps carried out on a production line:

• 1) transporting a metal strip to a profile planisher for planishing, and transporting the metal strip automatically to a subsequent process;
• 2) transporting the metal strip to a first rolling die set, rolling the metal strip to form a stiffener;
• 3) transporting the metal strip comprising the stiffener to a punching device, and punching the metal strip to form through holes;
• 4) transporting the punched metal strip to a second rolling die set, rolling the metal strip to yield a profile having a cross section in a required shape, the profile comprising an embedded flanging and an encircling flanging;
• 5) transporting the profile to a cutting device, cutting the profile to yield a first profile member;
• transporting the first profile member to a nesting device, rotating the first profile member for 180° in a direction of the cross section thereof, and positioning the first profile member;
• cutting the profile again to yield a second profile member;
• and inserting and nesting the first profile member in the second profile member to form a profile combination, whereby the encircling flanging of the first profile member contacting with a lateral side of the second profile member and the encircling flanging of the second profile member contacting with a lateral side of the first profile member;
• and
• 6) transporting the profile combination to a third rolling die set, shaping the encircling flangings of the first profile member and the second profile member into fixing flangings for fastening corresponding lateral sides, respectively, whereby yielding the nested profile combination;
• the system comprising:
• a) the profile planisher;
• b) the first rolling die set, the first rolling die set comprising a plurality of first rolling sets;
• c) a punching device, the punching device comprising a punching bed and a punching machine;
• d) the second rolling die set, the second rolling die set comprising a plurality of second rolling sets;
• e) the cutting device, the cutting device comprising a cutter;
• f) the nesting device;
• and
• g) the third rolling die set, the third rolling die set comprising a third rolling set;
• wherein:

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