Rebar straightening machine operating procedures

1. According to the diameter of the straightened steel bar, select the appropriate straightening block, pulley groove and transmission speed. The hole diameter of the straightening block should be 2~5mm larger than the diameter of the steel bar, and the groove width of the electric pulley should be the same as the diameter of the straightened steel bar.

2. Adjustment of straightening block. There are five straightening blocks in a general straightening cylinder. The first and fifth straightening blocks must be placed on the center line, and the middle three can be offset from the center line. First offset the steel bar by an offset of about 3mm. After trial adjustment, if the steel bar is still bent slowly, gradually increase the offset until it is straightened.
3. After cutting three or four steel bars, stop the machine to check whether the length is appropriate. If there is any deviation, adjust the limit switch or the fixed-length plate until it is suitable.
4. A steel bar of about 1 meter should be installed at the front of the guide pipe. The straightened steel bars should first pass through the steel pipe, and then pass through the guide tube and straightening tube to prevent each plate of steel bars from popping out and injuring people when the straightening is completed.
5. Before the straightening block is fixed and the protective cover is not covered, do not penetrate the steel bar to prevent the straightening block from flying out and injuring people after starting the machine.
6. Do not stack objects on the machine to prevent mechanical vibration objects from falling into the machine body. When the steel bars are loaded into the pressing roller, a certain distance should be kept between the hands and the roller. The roller must not be adjusted while the machine is running, and it is strictly prohibited to wear gloves when operating.
7. When the steel bars are adjusted to the end, personnel must move away to prevent them from being thrown and hurting others. Straightening of steel bars shorter than 2m or with a diameter greater than 9mm should be processed at low speed.
