(1) When installing the bearing frame, the center line of the bearing frame material slot should be aligned with the center line of the guide cylinder, straightening cylinder and cutter hole. (2) After installation, first check whether the electrical system and other components are damaged, whether the machine connection parts are firm and reliable, and whether the transmission parts are flexible. After confirming that all parts are normal, the test run can be carried out. During the test run, the bearing temperature should be checked, and the hammer head, cutter and shear gear and other workpieces should be checked to see if they are normal. After confirming that there are no abnormal conditions, feeding, test straightening and cutting can be carried out. (3) According to the diameter of the steel bar to be straightened, select appropriate straightening blocks, traction wheel grooves and transmission speeds. The hole diameter of the straightening block should be 2mm~5mm larger than the diameter of the steel bar, and the width of the traction wheel groove should be consistent with the diameter of the steel bar to be straightened. (4) Pay attention to adjusting the straightening blocks. There are generally five straightening blocks in the straightening box. The first and fifth straightening blocks must be placed on the center line, and the middle three can deviate from the center line. First, the steel bar is offset by about 3mm. After trial straightening, if the steel bar still has slow bending, the offset can be gradually increased until it is straightened. (5) A steel pipe about 1m long should be installed in front of the guide cylinder. The steel bars to be straightened should first pass through the steel pipe, and then pass through the guide cylinder and the straightening cylinder to prevent the end of each coil of steel bars from popping out and injuring people when the straightening is almost completed. (6) Before the straightening block is fixed and the protective cover is not covered, the steel bars must not be inserted to prevent the straightening block from flying out and injuring people after the machine is started.
