[0002] The straightening machine is mainly used to solve the bending deformation problem that may occur in shaft products after heat treatment. It usually includes a high-precision measurement system that can accurately measure the radial runout of the workpiece and determine the maximum bending position and direction through computer analysis. According to the measurement data of the workpiece, the straightening machine will calculate and apply appropriate pressure to straighten the workpiece at the maximum bending point. In this process, tooling is usually used to fix the shaft workpiece and rotate it to contact the straightening point at different angles. At the same time, a pressure block mechanism is set on the top of the straightening machine, and the pressure on the straightening point is applied to straighten it through the downward pressure of the pressure block mechanism.
