[0029] Embodiment 2

[0030] During the long-term use of the bending machine, it will be continuously affected by the force from above, resulting in easy deformation, making the brackets of the bending machine uneven in height during bending, affecting the service life;

[0031] For the above problems, refer to Figure 3 and Figure 4 As shown, the two straightening rods 3 are composed of a first slider 301, a second slider 302, a first connecting rod 303 and a second connecting rod 304.

The adjusting rod 603 cooperates with the straightening mechanism 2 to increase the stability of the bending machine frame 1. And when the frame 1 is deformed, the distance between the first fixing rod 601 and the second fixing rod 602 and the adjusting rod 603 can be adjusted to achieve the adjustment effect, thereby achieving compensation.

[0036] Working principle: When the frame 1 is deformed during the use of the bending machine, first, the straightening operation can be carried out through the telescopic rod 6 located on the back of the cross bar 103.

Subsequently, it is adjusted through the straightening mechanism 2 on the outer surfaces of the first plate 101 and the second plate 102. During the adjustment, first loosen the fixing bolt 5 respectively, so that the threaded rod two 503 at the end of the fixing bolt 5 moves out of the fixing groove 702 in the second chute 7. Then move the position of the fixing bolt 5 in the second chute 7, and move outwards respectively, so that the included angle between the first connecting rod 303 and the second connecting rod 304 is enlarged, so that the first slider 301 and the second slider 302 located at one end of the first connecting rod 303 and the second connecting rod 304 play a role in straightening the upper and lower ends of the first plate 101 and the second plate 102. After adjusting to the appropriate position, tighten the fixing bolt 5, so that the threaded rod two 503 at the end of the fixing bolt 5 is screwed into the corresponding fixing groove 702 in the groove 701 of the second chute 7, thereby completing the straightening for preventing deformation compensation operation.
