Abstract
A torque control method and apparatus for bolt tightening within predetermined rounds are provided. The method includes the following steps: connecting a torque control apparatus between an air supply system and a torque tool; generating a plurality of flow sets by the torque control apparatus according to the maximum air consumption of the torque tool under loading; obtaining the highest and lowest working air pressures and the corresponding maximum and minimum torque values according to each flow set, thereby constructing a relation curve between a plurality of working air pressure values and torque values; and obtaining the maximum controlling range under a working air pressure condition that the torque tool can be normally operated according to a relation curve between a plurality of working air pressures and torque values.
