1. Install the frame to bear the center line of the feed trough to the quasi-guide tube, as well as the center line of the straight hole.2. After installation, you should first check whether the electrical system and other components are damaged, whether the machine connection parts are reliable, and whether the transmission parts are flexible.Make sure all parts are normal before trial operation.During the trial operation, the bearing temperature should be checked to see if the workpieces such as hammers, knives, shears, etc. are normal.Make sure there are no abnormalities before feeding, testing, straightening and cutting.3. Adjust the steel bar diameter as needed and select the appropriate straightening block, traction wheel groove and transmission speed.The diameter of the straightening block should be 2 mm to 5 mm larger than the diameter of the steel bar, and the width of the traction wheel should be consistent with the diameter of the steel bar.4. Pay attention to adjusting the straightening block.St
