Design and Analysis of Nut Crimping Machines


Article Preview

In view of the growing market demand for self-locking nuts and the relative backward processing technology, a nut crimping machine was studied. According to the working principle of nut crimping and performance requirements, the body structure of the nut crimping machine was designed. The stress analysis of the main stressed components was performed using simulation Xpress function of SolidWorks. Results show that body structure has high strength and rigidity. Based on electro-hydraulic proportional technology, the hydraulic control circuit was developed. The design results improve the control precision on speed and pressure of the nut crimping machine and ensure the quality of self-lucking nuts.
