By setting the structures of the extension plate 21, the plug block 24, the end holes 25, the spring pin 26, the slot 27, the positioning holes 28, the connecting sleeve block 29 and the bolt group 30, during the use process, on the one hand, the limit shell 8 can be replaced to adapt to various sizes of steel materials, and on the other hand, the auxiliary plate 18 can be lengthened by using the extension plate 21 to further match materials of various sizes.

[0037] Working principle: During the use of this bending machine, first determine the specific size of the material and judge whether the limit shell 8 and the auxiliary plate 18 need to be adjusted. If adjustment is required, at this time, the staff can directly remove the bolt group 30, and then the connecting sleeve block 29 is separated from the bottom end of the electric push rod 7, and the limit shell 8 can be directly removed and a new limit shell 8 can be replaced. When adjusting the auxiliary plate 18, at this time, the staff can pick up the extension plate 21 and insert the plug block 24 into the slot 27. The spring pin 26 will snap into the positioning hole 28 to realize the connection between the extension plate 21 and the auxiliary plate 18. Then, use the lever 20 and the end block 19 to drive the lead screw 16 to rotate, and the distance between the auxiliary plates 18 can be adjusted to adapt to materials of various sizes. During the bending process, first, the staff turns on the electric push rod 7, which then drives the limit shell 8 to move up and down. During the adjustment process, the scale 11 on the surface of the guide post 9 can be observed to ensure the position accuracy of the limit shell 8. Then, turn on the hydraulic cylinder 5, and the hydraulic cylinder 5 will drive the bending block 6 to move and bend the material until the two end points of the material fit against the inner wall of the limit shell 8, and the specified bending angle can be achieved. The operation is simple and convenient.
