Since the driving gear 3212 is respectively engaged with the first transmission gear 3213 and the second transmission gear 3214, the first lower pressing roller 322 and the second lower pressing roller 323 can be driven to rotate relative to each other.

[0030] In some embodiments, the clamping assembly 200 includes a clamping translation member 230 , and the clamping translation member 230 is transmission-connected to the first slide 210 to drive the first slide 210 to slide relative to the frame 100 .

[0033] In some embodiments, the second slide 310 includes a connecting rod 311 and two oppositely arranged C-shaped frames 312, both ends of the connecting rod 311 are fixedly connected to the C-shaped frames 312, and both ends of the first lower pressure roller 322, the second lower pressure roller 323 and the upper pressure roller 324 are rotatably mounted on the two C-shaped frames 312 respectively.

[0034] In this embodiment, since the two ends of the first lower pressing roller 322, the second lower pressing roller 323 and the upper pressing roller 324 are rotatably installed on the two C-frames 312 respectively, the gap of the extrusion gap is opposite to the opening of the C-frame 312, and the steel plate is discharged from the gap through the opening of the C-frame 312, which can avoid the second slide 310 hindering the steel plate from escaping from the extrusion gap.

[0035] In some embodiments, the first slide seat 210 is provided with a slot 211 , and a side wall of the slot 211 is in contact with an edge of a steel plate on the first slide seat 210 .

[0040] By pushing the second slide 310 through the bending translation member 330, the second slide 310 can be driven to slide relative to the frame 100. When the bending member 320 approaches the steel plate fixed on the first slide 210, the end of the steel plate is introduced into the bending gap, and the rotation drive unit 321 drives the first lower pressing roller 322 and the second lower pressing roller 323 to rotate relative to each other. Under the pressure of the first lower pressing roller 322, the second lower pressing roller 323 and the upper pressing roller 324, one end of the steel plate can be bent. Afterwards, another first slide 210 can be pushed so that another bending member 320 approaches the end of the steel plate that has not been bent and bends it. Finally, the first slide 210 is made to slide and drive the steel plate fixed on the first slide 210 to separate from the two bending members 320, and the bending operation of the steel plate can be completed. Using the above-mentioned bending device for oil tank processing, the two ends of the steel plate can be bent respectively, and then a profile with a straight middle part and curved ends can be quickly obtained, thereby improving the processing efficiency of the oil tank.
