After the servo motor 104 is closed, an operator presses the installation shell 202 downwards to compress a spring between the installation shell 202 and the fixed rod 106, when the lower side surface of the installation shell 202 is attached to the movable frame 105, the operator pulls the pull rod 203 upwards to enable negative pressure to be formed between the pull rod 203 and the movable frame 105, when the pull rod 203 contacts the symmetrically arranged first limiting rods 205, the pull rod 203 presses the symmetrically arranged first limiting rods 205 to enable the two symmetrically arranged first limiting rods 205 to move back, the spring between the first limiting rods 205 and the installation shell 202 is compressed, when the axis of the first limiting rods 205 is overlapped with the axis of the adjacent limiting holes 204, the first limiting rods 205 enter the adjacent limiting holes 204, the first limiting rods 205 limit the pull rod 203 through the adjacent limiting holes 204, the operator releases the installation shell 202, at the moment, the negative pressure between the pull rod 203 and the movable frame 105 enables the installation shell 202 to be tightly attached to the movable frame 105, the movable frame 105 and the fixed rod 106 do not slide relatively, the bending radius of a pipe fitting a is prevented from changing, and the quality of a pipe fitting a is not qualified in a bending process is reduced.
When the limit of the first limiting rod 205 to the pull rod 203 needs to be released, an operator presses the movable ring 207 downwards, the movable ring 207 drives the two second limiting rods 208 to move downwards, the second limiting rods 208 extrude inclined planes of extrusion grooves on the adjacent mounting blocks 206, so that the two symmetrically arranged mounting blocks 206 drive the adjacent first limiting rods 205 to move back, springs between the first limiting rods 205 and the mounting shells 202 are compressed, and when the first limiting rods 205 are separated from the adjacent limiting holes 204, the pull rod 203 moves downwards under the action of negative pressure between the pull rod 203 and the movable frame 105, and under the action of spring force between the mounting shells 202 and the fixed rods 106, the mounting shells 202 move upwards and lose contact with the movable frame 105.
Then, an operator starts the heating ring 111, the heating ring 111 heats the pipe fitting a, after the pipe fitting a reaches the temperature of plastic deformation, the operator starts the water pump 113 and the pushing device 115, the pushing device 115 pushes the pipe fitting a to enable the pipe fitting a to move rightwards, the pipe fitting a drives the fixing ring 107 to move through the locking rod 109 of the annular array, the fixing ring 107 drives the sliding rod 108 to slide on the upper side face of the supporting plate 101, the right end of the pipe fitting a and the fixing ring 107 start to rotate by taking the axis of the rotating shaft on the movable block 102 as the center of a circle, the right end of the pipe fitting a is gradually bent, the core rod supports and extrudes the inside of the pipe fitting a, the pipe fitting a is reversely compressed and deformed in the bending process of the pipe fitting a, the metal tissue of the pipe fitting a is enabled to deform and refine at high temperature, the strength and toughness indexes of each part of the elbow are guaranteed to be uniform and consistent, and the quality of the pipe fitting a is improved.

After the pipe fitting a is bent, an operator closes the pushing device 115, after the pipe fitting a is cooled, the operator closes the water pump 113 and reversely rotates the locking rod 109 of the annular array to enable the locking rod 109 to lose contact with the pipe fitting a, then the operator rotates the rotating ring 302 to enable the torsion spring on the rotating ring 302 to be subjected to torsion, the rotating ring 302 extrudes the adjacent third guide rods 304 through the first limiting groove 3021 and the second limiting groove 3022 on the rotating ring 302, the six third guide rods 304 distributed circumferentially drive the adjacent extrusion blocks 303 to be far away from the axis of the rotating ring 302, the operator takes out the pipe fitting a and releases the rotating ring 302, and the rotating ring 302 is reset under the torsion force of the torsion spring on the rotating ring 302.
