The pusher rod 108 is connected to the side of the pusher oil cylinder 107 near the material fixing frame 106. The blanking flat plate 109 is arranged between the pusher rod 108 and the material fixing frame 106 and is connected to the fixed frame 105. A connecting piece for connecting the forming grinding tool is provided at the bottom of the blanking platform. A blanking port is provided directly below the forming die 201 on the frame 104. The material receiving box 116 is arranged directly below the blanking port and is connected to the bottom of the frame 104. Two feeding frames 110 connected to the top of the fixed frame 105 are symmetrically arranged on the upper side of the blanking platform. Two first bending oil cylinders 112 are symmetrically arranged on both sides of the clamping oil cylinder 111. The second bending oil cylinder 113 and the third bending oil cylinder 114 are respectively arranged on both sides of the blanking flat plate 109. A clamping block 202 is driven and connected to one end of the clamping oil cylinder 111 facing the forming die 201. A roller 203 is connected to one end of the first bending oil cylinder 112, the second bending oil cylinder 113, and the third bending oil cylinder 114 facing the forming die 201. The hydraulic device 102 is arranged on one side of the frame 104 and is respectively connected to the pusher oil cylinder 107, the clamping oil cylinder 111, the first bending oil cylinder 112, the second bending oil cylinder 113, and the third bending oil cylinder 114.

[0019] A fully automatic bending machine provided in this embodiment adopts a control device 101 which includes a controller 115 and sensors 208. Sensors 208 are connected to the first bending oil cylinder 112, the second bending oil cylinder 113, the third bending oil cylinder 114, and the blanking port. The sensors 208 are connected to the controller 115. The controller 115 controls and connects the first bending oil cylinder 112, the second bending oil cylinder 113, and the third bending oil cylinder 114 respectively. The controller 115 is reversely linked to connect the pusher oil cylinder 107 and the clamping oil cylinder 111. When the sensors 208 detect that the corresponding work fails, they will feedback to the controller 115 and stop working.

[0020] As Figure 2 shown, for a fully automatic bending machine provided in this embodiment, a material fixing frame 106 connected to the top of the frame 104 is provided directly below each loading rack 110. Through holes for material fixing grooves 204 are provided at one ends of the two material fixing frames 106 facing the blanking platform. A limiting member 205 is connected to one side of each material fixing frame 106 facing the fixing frame 105. An internal limiting groove 206 communicating with the material fixing groove 204 for placing a rotating limiting component is provided inside the limiting member 205. During use, when the loading rack 110 is filled with materials and the materials fall onto the top of the blanking flat plate 109, since the controller 115 is reversely linked to connect the pusher oil cylinder 107 and the clamping oil cylinder 111, when the controller 115 controls the pusher oil cylinder 107 to push the pusher rod 108 to push the materials into the material fixing groove 204 in the material fixing frame 106, the controller 115 controls the clamping oil cylinder 111 to push the clamping block 202 forward to clamp the materials between the clamping block 202 and the forming die 201. At this time, the controller 115 controls the pusher oil cylinder 107 to retract the pusher rod 108 to make the materials move down one unit. Subsequently, the controller 115 controls the two first bending oil cylinders 112 to work simultaneously to bend the materials. When the sensors 208 detect that the first bending oil cylinder 112 returns to its position, the controller 115 controls the second bending oil cylinder 113 to work. When the detector detects that the second bending oil cylinder 113 returns to its position, the controller 115 controls the third bending oil cylinder 114 to work. When the materials fall into the material receiving box 116 and are detected, the controller 115 controls the third bending oil cylinder 114 to return to its position and controls the pusher oil cylinder 107 to perform repetitive work.

[0021] As Figure 3As shown, a fully automatic bending machine provided in this embodiment adopts a rotary limit assembly including a rotary limit rod 301, a rotary limit block 302, and a torsion spring 303. The upper and lower ends of the rotary limit rod 301 are connected to the limit member 205. The torsion spring 303 is sleeved on the rotary limit rod 301. The rotary limit block 302 is sleeved on the rotary limit rod 301 and connected to the torsion spring 303. When in use, when the material falls into the solid material groove 204, in order to prevent the material from being defective due to the influence of the solid material rack 106 during bending, an opening is cut out on the solid material rack 106 behind the material. However, the material will move in the opening and cause it to fall off. Therefore, the additional rotary limit block 302 matches the torsion spring 303, which can prevent the material from moving and move along with the bending of the material without causing damage to the material, and automatically return to its original position when the bending is completed in sequence.

[0022] In a fully automatic bending machine provided in this embodiment, a pushing oil cylinder 107 is provided with a pushing driving rod 207 connected to a pushing rod 108, and a spring is connected between the pushing rod 108 and the pushing driving rod 207.
