[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] As shown in the drawing, Figs. 1-2 The sheet metal bending machine of the embodiment includes a workbench 1 and a support leg 2 at the bottom of the workbench 1. The workbench 1 is provided with a recess 3. The recess 3 is fixedly installed with a hydraulic cylinder 4 at the bottom. The hydraulic cylinder 4 is fixedly installed with a first fixed rod 5 at the top left side. The first fixed rod 5 is fixedly installed with a first pressing head 6 at the top. The first fixed rod 5 is fixedly installed with a second fixed rod 7 at the right side. The second fixed rod 7 is fixedly installed with a second pressing head 8 at the top. The recess 3 is symmetrically provided with a first limiting rod 9 at the front and the back. The first pressing head 6 can bend into the required radian in cooperation with the first limiting rod 9. The first limiting rod 9 is provided with a second limiting rod 10 at the right side. The second pressing head 8 can bend into the required angle in cooperation with the second limiting rod 10. The first limiting rod 9 and the second limiting rod 10 are provided with a scale line 11 at the position. The scale line 11 is used to refer to the angle or the radian of the bending part.

[0021] Further, the first pressing head 6 is arc-shaped, and the second pressing head 8 is triangular.

[0022] Further, the first fixed rod 5 and the second fixed rod 7 are both sleeved with a rotating sleeve 12. The use of the rotating sleeve 12 can reduce the damage caused by the friction between the sheet metal part and the first fixed rod 5 or the second fixed rod 7.

[0023] Working principle: when the sheet metal part needs to be folded into an arc-shaped structure, it is placed on the left side of the first limiting rod 9; when it needs to be bent at an angle, it is placed on the left side of the second limiting rod 10; the bending position is against the left side of the first pressing head 6 or the second pressing head 8; when the hydraulic cylinder 4 drives the first pressing head 6 or the second pressing head 8 to move to the right, the first pressing head 6 or the second pressing head 8 can bend the sheet metal part in cooperation with the first limiting rod 9 or the second limiting rod 10, and the angle or the radian of the bending can be referenced by the scale line 11. During the bending process, the sheet metal part will simultaneously drive the rotating sleeve 12 to rotate.
