s2, starting a pair of first air cylinders (7) through a main controller (4), shortening the length of the first air cylinders to enable a left inserted rod (21) to move left, inserting the left end of a right inserted rod (22) into a steel pipe (13) to 6-8cm, enabling the left end of the steel pipe (13) to be in a level state, starting the pair of first air cylinders (7) through the main controller (4), extending the length of the first air cylinders to enable the left inserted rod (21) to move right, enabling the left inserted rod to be inserted into the steel pipe (13), enabling the insertion depth to be 6-8cm, and closing the first air cylinders (7);
s3, starting the second cylinder (9) through the main controller (4), extending the length of the second cylinder to enable the steel pipe (13) to be located in the lower heat-insulating layer (17), loosening the locking screw (19), adjusting the position of the sliding sleeve (18), enabling the upper semicircular heating cylinder (12) to be located on the right upper side of the lower semicircular heating cylinder (10), starting the third cylinder (11) through the main controller (4), extending the length of the third cylinder to enable the upper semicircular heating cylinder (12) to be in contact with the lower semicircular heating cylinder (10) to enable the upper semicircular heating cylinder to be closed, and enabling the steel pipe (13) to be located between the upper heat-insulating layer (16) and the lower heat-insulating layer (17);
s4, starting a lower arc-shaped heating plate (14) and an upper arc-shaped heating plate (15) through a temperature controller (20), heating the temperature by the precise controller to 100 ℃, and heating for 15-20 min;
s5, start third cylinder (11) and second cylinder (9) through master controller (4), shorten its length, adjust adjustable speed motor (32) to slow speed through master controller (4), and start adjustable speed motor (32), the output of adjustable speed motor (32) rotates and drives driving gear (33) and rotate, driving gear (33) rotate and drive driven gear (29) and rotate, thereby drive carousel (30) and rotate, make eccentric post (31) do the circular motion with thick pivot (28) axle center as the centre of a circle, thereby carry out the bending, when eccentric post (31) is moving according to fixed orbit, let it make the bending that steel pipe (13) can be accomplished to half circular motion.
