Abstract: The field of energy storage systems, especially the production of cabinet wiring harnesses, involves the crimping technology of primary wire terminals. In the existing technology, a single wire crimping is performed by the operator using manual crimping pliers to crimp the opposite side of the terminal. The crimping of the wire core will result in flying edges, which cannot meet the usage requirements during wiring. In order to solve this problem, a research was conducted on a hexagonal sliding type stepless adjustment control electric terminal machine, and equipment corresponding to configuration requirements, crimping parameters, and system composition was developed and researched. The structure and design parameters of a hexagonal tool-free crimping machine were tested, and crimping parameters for different specifications of wires were obtained, verifying the accuracy of crimping parameters and meeting process requirements. This electric terminal machine can work continuously for a long time, meet the requirements of terminal crimping, improve crimping efficiency by 30%, save labor costs, and reduce personnel fatigue during operation.
