[0029] It should be noted that the main body 1 is the main part of the bending machine; the upper pressing film 2 and the lower pressing film 3 can cooperate to effectively bend parts of the power distribution cabinet, such as the frame; the controller 4 can control the parts that need to be controlled; the calibration mechanism 5 is arranged inside the rear end of the main body 1, and can perform limit calibration on the parts placed on the lower pressing film 3, effectively ensuring the efficiency and accuracy of workpiece bending; the pushing platform 6 can facilitate the staff to place the parts that need to be bent, and can push the parts that need to be bent to the lower pressing film 3 and cooperate with the calibration mechanism 5 to perform position calibration on the parts that need to be bent; the controller 4 is a prior art, and those skilled in the art can fully understand it.

[0030] Specifically, the calibration mechanism 5 includes a first connecting plate 51, an electric hydraulic cylinder 52, a support plate 53, an electric telescopic rod 54, a second connecting plate 55, and a calibration piece 56; two first connecting plates 51 are detachably connected to the inner side wall of the rear end of the main body 1; two electric hydraulic cylinders 52 are fixedly connected to each first connecting plate 51; the output ends of the four electric hydraulic cylinders 52 are horizontally placed with the support plate 53; at least one electric telescopic rod 54 is detachably connected to the support plate 53; the output end of the electric telescopic rod 54 is vertically connected with the second connecting plate 55; the calibration piece 56 is bolted to the second connecting plate 55; the controller 4 is electrically connected to the electric hydraulic cylinder 52 and the electric telescopic rod 54 respectively. The first connecting plate 51 can facilitate the connection of components; the electric hydraulic cylinder 52 can adjust the height of the calibration mechanism 5; the support plate 53 facilitates the installation of the electric telescopic rod 54; the second connecting plate 55 is connected to the output end of the electric telescopic rod 54, which can facilitate the connection of the calibration piece 56; the calibration piece 56 can facilitate pushing the parts that need to be bent placed on the lower pressing film 3 to ensure the accuracy of calibration.

[0031] Specifically, in order to ensure sufficient power, two electric telescopic rods 54 are provided in this application.

[0032] Specifically, the correction member 56 includes a vertical connection end 561, a horizontal connection end 562, and a limiting end 563. One end of the horizontal connection end 562 is connected to the upper end of the vertical connection end 561, and the other end is connected to the lower end of the limiting end 563. The vertical connection end 561, the horizontal connection end 562, and the limiting end 563 are integrally formed. The vertical connection end 561 can facilitate bolt connection with the second connecting plate 55 for convenient disassembly and assembly. The horizontal connection end 562 can effectively reserve a telescopic position to prevent the correction member 56 from interfering with the lower pressing film 3 in terms of position. The limiting end 563 can contact and limit and correct the part to be bent.

[0033] Specifically, in order to ensure that the part to be bent can be limited, the upper horizontal height of the limiting end 563 is higher than the upper end of the lower pressing film 3.

[0036] Specifically, in order to improve the strength of the pushing platform 6, a support bar 63 for fixation is also connected between the platform vertical plate 61 and the platform horizontal plate 62.

[0037] The working principle of the present utility model:

[0038] When performing batch bending treatment on the components of the power distribution cabinet, first, the controller 4 is used to control the electric hydraulic cylinder 52 to adjust the height of the correction mechanism 5. After the height reaches the predetermined height, the electric telescopic rod 54 is adjusted again through the controller 4 until the components to be batch bent are exactly located at the center position of the predetermined bending position, ensuring absolute accuracy of the bending position. Then, the components to be batch bent are successively placed on the platform cross plate 62 between the lower pressing film 3 and the push block 64. Then, the platform cross plate 62 is pushed, so that the components to be bent are limited by the correction piece 56 and the platform cross plate 62 and are exactly located at the predetermined bending position below the upper pressing film 2 and the lower pressing film 3 for bending, effectively ensuring the accuracy of the bent components. At the same time, by fixing the positions of the components to be bent, the working efficiency is improved. When bending the components of the next batch, repositioning is carried out again. There is no need to reposition each component for bending, only different batches need to be positioned, which greatly shortens the working time.
