AI Technical Summary
During the contact manufacturing process, the size of the contact opening is easily deformed during electroplating, which leads to a decrease in installation accuracy and poor synchronization of the three-phase operation of the circuit breaker, increasing the defect rate and reducing production efficiency.
A contact shaping device is adopted, including a mounting block, a positioning block, and a shaping component. The shaping component can be inserted into the C-shaped part and opened or reset in a direction perpendicular to the opening to adjust the opening size of the C-shaped part.
It effectively solved the problem of contact opening size deformation, improved installation accuracy and the synchronization of three-phase operation of the circuit breaker, and increased production efficiency and pass rate.
