Specific embodiments

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0016] As Figures 1-3 shown, a door panel bending machine includes a bottom plate 1, a plate placing box 2 is fixedly connected to the bottom plate 1, an inserting plate groove 3 penetrating through the left and right sides of the plate placing box 2 is provided on the plate placing box 2, a sliding plate 4 is slidably connected in the inserting plate groove 3, the inserting plate groove 3 is also used to store the excavator door panel to be bent, the sliding plate 4 is used to position the excavator door panel. After inserting the excavator door panel into the door panel groove, align the part to be bent with the rightmost end of the inserting plate groove 3, and adjust and fix the sliding plate 4 to the corresponding position. The excavator door panel is fixed by the extrusion of the four inner walls of the inserting plate groove 3 and the side wall of the sliding plate 4. The left end of the sliding plate 4 is fixedly connected with a connecting block 5, and the connecting block 5 is slidably connected on a limiting block 6; at the position where the right end of the inserting plate groove 3 is close to its lower mouth surface, an arc-shaped block 7 is fixedly connected, one end of the arc-shaped block 7 is fixedly connected with a supporting block 8, the other end of the arc-shaped block 7 is fixedly connected with a casing 9, a connecting body 10 is connected in the casing 9, the connecting body 10 is fixedly connected to the machine shaft of a motor 11, one end of the connecting body 10 far from the machine shaft of the motor 11 is fixedly connected with one end of a connecting shaft 12, the motor 11 drives the connecting body 10 to rotate so that the connecting shaft 12 drives the heating roller 13 to move along the arc-shaped window 14 to bend the excavator door panel, the connecting shaft 12 is sleeved with a heating roller 13, and both ends of the connecting shaft 12 move in the arc-shaped window 14.

[0017] The connecting block 5 and the limiting block 6 are provided with through holes 15 of equal size penetrating through their upper and lower surfaces, and the distance between the through holes 15 is equal.
