[0002] Electronic detonator is an electric detonator that uses an electronic control module to precisely control the detonation process. It is mainly composed of a detonator, an encoder and an initiator. Compared with traditional industrial detonators, electronic detonators can achieve precise delay and detonation energy control through electronic control modules, thereby improving blasting efficiency and safety.

[0003] During the production process of electronic detonators, the wire ends need to be bent and connected to the detonator control module. Specifically, the wire ends are bent through the upper and lower mold plates by bending equipment to ensure the consistency of the dimensions after bending. However, the existing bending methods are all hard bending. If the clamping force is too large, indentations or damages are likely to occur at the excessively bent feet of the mold plates. If the clamping force is too small, the bend is prone to slight rebound, affecting the bending accuracy. Summary of the invention
