[0034] The bottom of the lower movable beam 4 is connected to the lifting component 6;

[0035] The lower die adjusting beam 3 is connected to the lower movable beam 4 through the adjusting component 5, and the adjusting component 5 is used to adjust the position of the lower die adjusting beam 3 in the Y-axis direction;

[0037] A convex portion adapted to the forming groove 21 is provided at the bottom of the pre-bending upper die 1.

[0038] Among them, the forming groove 21 on the upper surface of the pre-bending lower die 2 includes at least two continuous arc segments, the central angle angles corresponding to the two end arc segments are different, and the central angle difference corresponding to the two end arc segments is less than 10°.

[0039] During use, the pipeline or plate to be processed is placed between the pre-bending lower die 2 and the pre-bending upper die 1, and the lower movable beam 4 is driven to move upward through the lifting component 6 to realize the mold closing between the pre-bending lower die 2 and the pre-bending upper die 1, achieving the pre-bending effect. The lower die adjusting beam 3 can be driven to move through the adjusting component 5, so that the pre-bending lower die 2 and the pre-bending upper die 1 are misaligned. In this embodiment, the convex portion corresponding to the second arc segment in the pre-bending upper die 1 corresponds to the first arc segment in the pre-bending lower die 2. Due to the different radian of the two, it can meet the pre-bending processing of different pipe diameters and improve the practicability of the equipment.

[0040] It should be noted that, in the above embodiment, the convex portion corresponding to the second arc segment in the pre-bending upper die 1 corresponds to the first arc segment in the pre-bending lower die 2. Due to the different radian of the two, pipelines with pipe diameters between the radian differences of the two can be pre-bent.
