[0027] The supporting assembly 8 includes two L-shaped frames 81 fixedly installed on one side of the processing table 1 near the bottom and a support plate 82 fixedly installed on the L-shaped frame 81. A movable shaft 83 is rotatably connected at the middle position of the bottom of the support plate 82. A placement plate 84 is fixedly installed on the top of the movable shaft 83. The placement plate 84 is provided to support the rods, eliminating the need for manual straightening, thereby reducing the workload of the staff.

[0032] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 3 and Figure 5 The adjusting component 9 includes an adjusting disk 91 fixedly sleeved on the outer periphery of the movable shaft 83 near the middle position and a plurality of through holes opened at the bottom of the adjusting disk 91.

A spring B93 is movably sleeved on the outer periphery of the telescopic column B92, and the top and bottom ends of the spring B93 are fixedly connected to the adjacent connecting block 94 and the support plate 82 respectively. By adjusting the handle 911 to rotate the adjusting disk 91, the angle of the placement plate 84 can be deflected, so that it can be used to limit the more curved part of the rod, thereby improving the scope of application of the device.

[0033] A plurality of adjustment handles 911 are fixedly mounted on the outer periphery of the adjustment disk 91 . The plurality of adjustment handles 911 are arranged in a circular array with the top circle center of the adjustment disk 91 as the center. The adjustment handles 911 are provided to facilitate driving the adjustment disk 91 .

[0034] A pressing block 941 is fixedly installed on one side of the connecting block 94. The top of the pressing block 941 is arranged in an arc shape.

[0035] Working principle: When the utility model is used, the staff places the rod to be straightened on the top of the processing table 1 and the placement plate 84, and then starts the electric slide rail through the external controller to slide the support block B5 to the rear side, and adjusts the distance between the straightening roller A3 and the straightening roller B4, which is suitable for straightening operations of rods of different widths. Then, the drive motor 71 is started, and the rotation of the power output shaft of the drive motor 71 drives the adjacent rotating shaft 6 fixed on the shaft end of the power output shaft of the drive motor 71 to rotate, and the adjacent rotating shaft 6 can be rotated under the transmission of the transmission belt 72, thereby straightening the rod. By setting the L-shaped frame 81, the support plate 82, the movable shaft 83 and the placement plate 84, these components cooperate with each other, so that the longer rods to be straightened can be supported without the need for manual support by the staff, thereby reducing the labor of the workers. The working intensity of the staff is improved, and the straightening effect of the device is improved. By arranging the mounting plate 841, the telescopic column A842, the clamping plate 843 and the spring A8421, these components cooperate with each other, and the supported rod can be fixed to prevent shaking during straightening, thereby improving the use effect of the device. When the rod to be straightened is relatively curved, the pressing block 941 is pressed downward at this time to make the connecting block 94 move downward to squeeze the spring B93 and the telescopic column B92, so that the limiting column 95 fixed on the connecting block 94 is away from the inner cavity of the adjacent limiting hole, and then the adjusting handle 911 is driven to rotate the adjusting disk 91, and then the movable shaft 83 can be rotated, which can deflect the angle of the placing plate 84, and then it can be used to limit the relatively curved part of the rod, thereby improving the scope of application of the device.
