The kinematic coupling simulation of the changing roller locking pull-grip system of the high-stiffness row straightening machine,through the tangential slip analysis of the contact analysis of the pulling claw,to obtain the pulling claw slip and the contact force has a correlation with the pulling claw,the pulling claw after the flexibilization of the pulling claw,the stress field analysis of the pulling claw,the results show that the contact situation is close to the actual conditions,the locking pull-grip system of the straightening machine provides the theoretical basis for the design of the locking pull-grip system.
