[0024] Working principle: When it is necessary to bend the steel pipe to produce the backrest frame of the car seat, the frame bending machine body 3 is used to automatically bend the steel pipe to be bent to form a U-shaped backrest frame, and the U-shaped backrest frame is in a horizontal state after the bending is completed;

[0025] The U-shaped backrest frame is transported to the U-shaped shaping groove: the first motor 504 is started to rotate one circle, and the third rotating shaft 506 is driven to rotate one circle through the transmission action of the first synchronous belt and the first synchronous wheel, and then the rotating bar 507 is driven to rotate one circle with the third rotating shaft 506 as the axis, and then the connecting rod 508 is driven to move back and forth along the set track, and then the connecting block 509 and the reciprocating plate 510 are driven to move back and forth. When the reciprocating plate 510 moves in the direction close to the first motor 504, during this process, the roller 512 rolls along the L-shaped through hole, and then the moving shaft 511, the moving rod 513 and the electromagnetic plate are driven to move along the L-shaped track. The electromagnetic plate absorbs the already U-shaped backrest frame and drives the U-shaped backrest frame to move to the top of the U-shaped shaping groove along the L-shaped track. When the reciprocating plate 510 moves in the direction away from the first motor 504, it can drive the electromagnetic plate to return to the initial position along the L-shaped track, waiting to absorb the next U-shaped backrest frame;

[0026] When the U-shaped backrest frame moves to the top of the U-shaped shaping groove, the U-shaped backrest frame begins to be shaped: the second motor 602 is started to rotate a quarter turn (the first quarter turn) in the clockwise direction, driving the fourth shaft 604 to rotate a quarter turn, and then driving the second special-shaped gear 607 to rotate a quarter turn in the clockwise direction with the fourth shaft 604 as the axis, and then driving the corresponding third special-shaped gear 608 and sleeve 609 to rotate half a turn counterclockwise with the fixed shaft 605 as the axis, and through the transmission action of the third synchronous belt and the third synchronous wheel, the sixth shaft 612 is driven to rotate half a turn, and then the second turntable 615 and the second cylindrical pin 616 are driven to rotate half a turn with the sixth shaft 612 as the axis, and ... The cylindrical pin 616 slides along the opening, thereby driving the sector gear 618 and the swing bar 617 to swing to a set angle, thereby driving the spur gear 404 to rotate three quarters of a circle in the clockwise direction with the first rotating shaft 403 as the axis, thereby driving the rotating bar 405 and the mounting plate 406 to rotate three quarters of a circle in the clockwise direction with the first rotating shaft 403 as the axis, so that the mounting plate 406 is in a horizontal state, and the electromagnetic strip is arranged opposite to the U-shaped backrest frame located at the top of the U-shaped shaping groove. At this time, the clamping block 410 is firmly clamped on the plug-in slot 611, and the second motor 602 is started to make it continue to rotate a quarter of a circle (the second quarter of a circle) in the clockwise direction, at this time driving the first special-shaped gear 606 to rotate a quarter of a circle with the fourth rotating shaft 604 as the axis. The third special-shaped gear 608 and the sleeve 609 corresponding thereto rotate half a circle counterclockwise around the fixed shaft 605 as the axis, and the fifth rotating shaft 610 is driven to rotate half a circle by the transmission action of the second synchronous belt and the second synchronous wheel, and the plug-in slot 611 and the clamping block 410 are driven to rotate half a circle around the fifth rotating shaft 610 as the axis, and the first rotating disk 411 is driven to rotate half a circle around the fifth rotating shaft 610 as the axis, so that the first cylindrical pin 412 slides in the annular bar 415, and the lifting bar 414 and the annular bar 415 are driven to move downward by a set distance, and the lifting plate 416 and the lifting block 417 are driven to move downward by a set distance, so that the U-shaped backrest frame is completely pushed into the U-shaped shaping groove, thereby completing the shaping of the U-shaped backrest frame. The U-shaped backrest frame is moved upwards by the movable plate 420, and the U-shaped backrest frame is pushed out of the U-shaped shaping groove to avoid the U-shaped backrest frame being stuck in the U-shaped shaping groove. The second motor 602 is started to rotate a quarter turn (the fourth quarter turn) in the clockwise direction to drive the mounting plate 406 back to the original position, and the U-shaped backrest frame is moved to the top of the placement rack 7.The U-shaped backrest frame falls on the placement rack 7 and slides down along the slope of the placement rack 7 for temporary storage.
