After the bending is completed, the first electric push rod 7 is started to drive the cutter 8 to press the steel plate down for cutting, and then the conveying mechanism 2 continues to drive the steel plate forward, squeezes the cut shell off the operating platform 1 and continues to bend, thereby realizing continuous work and higher work efficiency.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the conveying mechanism 2 includes a second motor 15 fixedly mounted on one side of the operating platform 1 , and a plurality of conveying rollers 16 rotatably mounted on the inner side of the operating platform 1 , and the output end of the conveying mechanism 2 is connected to the conveying rollers 16 via a chain 17 .

[0029] The chain 17 is driven by the second motor 15 to drive the conveying roller 16 to rotate, thereby driving the steel plate to move forward.

[0030] In this embodiment, if Figure 1 , Figure 2 and Figure 6As shown, a limiting mechanism is arranged between the conveying mechanism 2 and the cutting mechanism 3, and the limiting mechanism comprises a third motor 18 fixedly mounted on the front face of the operating platform 1 and a bidirectional lead screw 19 connected to the output end of the third motor 18, two limiting rods 20 are mounted on the outer side of the bidirectional lead screw 19, a slider 201 threadably matched with the bidirectional lead screw 19 is fixedly connected to the bottom of the limiting rod 20, a rotating sleeve 202 is rotatably mounted on the outer side of the limiting rod 20, a nut 203 is mounted on the top of the limiting rod 20, and a through slot 193 located between the conveying mechanism 2 and the cutting mechanism 3 and matched with the limiting mechanism is provided on the top of the operating platform 1.

Through the setting of the rotating sleeve 202, the steel plates can be moved forward while being positioned.

[0038] Step 2: After one end of the steel plate passes through the bending mechanism 5 and reaches the required bending width, the conveying mechanism 2 stops running, the second electric push rod 13 drives the pressing plate 14 to press on the steel plate, and then the first motor 11 drives the rotating frame 12 to rotate to bend the steel plate, and then the first motor 11 reverses to drive the bending mechanism 5 to separate from the steel plate;
