Description

Technical Field

[0001] This utility model relates to the field of circuit breaker manufacturing technology, and in particular to a tooling for stamping and forming the center hole of a circuit breaker frame. Background Technology

[0002] Circuit breaker frames play a crucial role in modern power systems, primarily in the following aspects: 1) Protecting circuit safety: When overloads, short circuits, or other faults occur in the circuit, the circuit breaker frame can quickly and reliably interrupt the circuit, avoiding or reducing accidents and protecting electrical equipment and personnel safety. This is its most basic and critical function. 2) Controlling current: The circuit breaker frame can control the magnitude and direction of current, playing a role in regulating and controlling current. 3) Isolating circuits: During maintenance, repair, or safety maintenance of electrical equipment, the circuit breaker frame can isolate electrical equipment, cutting off the circuit between them to protect the safety of personnel. 4) Stabilizing power system operation: The circuit breaker frame can quickly detect abnormal currents or voltages in the circuit and automatically disconnect the circuit, preventing overcurrent, overvoltage, and other problems from affecting the normal operation of the power system, ensuring the stability and safety of the power system. 5) Coordinating the power system: The circuit breaker frame can also coordinate various parts of the power system, preventing overloading or other faults, thereby improving the efficiency and reliability of the power system. 6) Circuit status detection: The frame circuit breaker has a fault detection function, which can automatically detect the circuit status and promptly alarm when the circuit is abnormal. It can also record historical fault information of the circuit.

[0003] The center hole of most circuit breaker frames is a straight-line structure, which means that it can only support pressing the upper and lower sockets. Therefore, our company has improved the center hole to a cross-shaped structure, so that it can support pressing the upper and lower sockets as well as pressing the left and right sockets.

[0004] The existing tooling for stamping the center hole of the circuit breaker frame has several shortcomings. First, it cannot quickly position the circuit breaker frame, which is not conducive to stamping. Second, it cannot perform deburring on the inner wall of the cross-shaped center hole after stamping. Therefore, it needs to be optimized and improved. Utility Model Content
