[0039] Initially, the staff puts the part of the workpiece 86 that needs to be bent downward and inserts it from the discharge port on the top of the main frame 2, so that the workpiece 86 passes between the pressure frame 5 and the flattening frame 78, and makes the bottom of the workpiece 86 contact the top of the support frame 84, the stabilizing frame 81 and the round shaft 83 press against the support frame 84, and then support the workpiece 86, the clamping spring 79 applies elastic force, so that the flattening frame 78 drives the ball 710 to flatten the workpiece 86 on the pressure surface of the pressure frame 5, after the workpiece 86 is placed, the staff starts the two servo self-locking motors 61, the output shaft of the servo self-locking motor 61 rotates to drive the sprocket 1 62 to rotate, the sprocket 1 62 rotates through the chain 65 to drive the sprocket 2 64 to rotate, the sprocket 2 64 rotates to drive the rotating frame 63 to rotate, and the rotating frame The rotation of 63 drives gear three 71 and bending roller 66 to rotate, the rotation of gear three 71 drives gear four 73 to rotate, the rotation of gear four 73 drives shaft 72 to rotate, the rotation of shaft 72 drives cam 74 to rotate, cam 74 rotates and contacts clamping frame 76, and squeezes clamping frame 76 in the direction close to pressure frame 5, reset spring 77 is compressed, clamping frame 76 moves in the direction close to pressure frame 5, drives flattening frame 78, clamping spring 79 and ball 710 to move in the direction close to pressure frame 5, workpiece 86 presses flattening frame 78 and ball 710, flattening frame 78 and ball 710 retract into clamping frame 76, clamping spring 79 is stretched, clamping frame 76 continues to move and contacts with workpiece 86, through the above operation, it is convenient to quickly The workpiece 86 is clamped to reduce the time spent on clamping the workpiece 86 and improve work efficiency. When the gear 3 71 rotates, it drives the rack 1 82 to move horizontally. The horizontal movement of the rack 1 82 drives the stabilizing frame 81 to move horizontally. The horizontal movement of the stabilizing frame 81 drives the round shaft 83 and the top plate 85 to move horizontally. When the bending roller 66 rotates to about to contact the workpiece 86, the round shaft 83 is out of contact with the support frame 84. Under the action of gravity, the support frame 84 will rotate downward to face vertically downward. Through the above operation, the workpiece 86 can be bent without contacting the support frame 84, avoiding the support frame 84 from pressing against the workpiece 86 and causing wear on the two. The bending roller 66 continues to rotate to drive the lower part of the workpiece 86 to bend ninety degrees along the fillet of the lower part of the pressure frame 5. After the bending is completed, the staff adjusts the servo self-locking motor 61 to rotate in the opposite direction. The output shaft of the servo self-locking motor 61 rotates in the opposite direction to drive the sprocket wheel 1 62 to rotate in the opposite direction. The sprocket wheel 1 62 rotates in the opposite direction through the chain 65 to drive the sprocket wheel 2 64 to rotate in the opposite direction. The sprocket wheel 2 64 rotates in the opposite direction to drive the rotating frame 63 to rotate in the opposite direction. The rotating frame 63 rotates in the opposite direction to drive the gear 3 71 and the bending roller 66 to rotate in the opposite direction. The gear 3 71 rotates in the opposite direction to drive the gear 4 73 to rotate in the opposite direction. The gear 4 73 rotates in the opposite direction to drive the rotating shaft 72 to rotate in the opposite direction. The rotating shaft 72 rotates in the opposite direction to drive the cam 74 to rotate in the opposite direction. After the cam 74 rotates in the opposite direction for a distance, it disengages from the clamping frame 76. The reset spring 77 rebounds and drives the clamping frame 76 to move in the direction away from the pressure frame 5.The clamping frame 76 moves in the direction away from the pressure frame 5, driving the flattening frame 78, the clamping spring 79 and the ball 710 to move in the direction away from the pressure frame 5. During the movement of the clamping frame 76, the clamping spring 79 will rebound and drive the flattening frame 78 and the ball 710 to move in the direction close to the pressure frame 5. The bending roller 66 continues to rotate in the opposite direction to disengage the workpiece 86. Under the action of gravity, the workpiece 86 will disengage from the pressure frame 5 and the ball 710 and fall downward. Through the above operation, the workpiece 86 can be quickly discharged after bending, further improving the work efficiency. The reverse rotation of gear three 71 drives the rack one 82 to move in the opposite direction. The rack 82 moves in the opposite direction to drive the stabilizing frame 81 to move in the opposite direction, and the stabilizing frame 81 moves in the opposite direction to drive the round shaft 83 and the top plate 85 to move in the opposite direction. After the workpiece 86 falls downward, the top plate 85 contacts the support frame 84 and pre-lifts the support frame 84 upward for a certain distance, thereby reducing the thrust required for the subsequent stabilizing frame 81 and the round shaft 83 to push the support frame 84 upward. The stabilizing frame 81 and the round shaft 83 continue to move in the opposite direction to lift the support frame 84 upward to the initial position, and the stabilizing frame 81 and the round shaft 83 are pressed against the support frame 84 again. Then the staff turns off the servo self-locking motor 61 and takes away the fallen workpiece 86, which is convenient for the next work.

The limit plate 96 is located above the discharge port of the main frame 2. When the workpiece 86 is inserted, the lower part of the workpiece 86 pushes the limit plate 96 downward, and the limit plate 96 will rotate downward. The torsion spring 97 is twisted to prevent the limit plate 96 from blocking the workpiece 86 from moving downward. After the workpiece 86 is inserted, it disengages from the limit plate 96. The torsion spring 97 will rebound and drive the limit plate 96 to rotate upward and reset. When the clamping frame 76 moves in the direction close to the pressure frame 5, it drives the rack two 91 to move horizontally. The horizontal movement of the rack two 91 drives the gear five 93 to rotate. The rotation of the gear five 93 drives the transmission frame 92 to rotate. The rotation of the transmission frame 92 drives the slotted frame 94 to move downward.
