Abstract

The invention relates to a production process of a thermal element for a circuit breaker. The method comprises the following steps: S1, putting a metal plate into a laser cutting machine, cutting to form a thermal element plate with required shape and size, and cutting a plurality of through holes in the thermal element plate; S2, tapping part of the through holes of the thermal element plate through a tapping machine; S3, putting the thermal element plate into a bending machine, and bending the thermal element plate into a specified shape; S4, sequentially placing the bent thermal element plates on a hollowed-out conveying belt, and using a flushing device to flush the thermal element plates through a first cleaning agent containing fine bubbles; S5, putting the thermal element plates into an ultrasonic cleaning pool containing a second cleaning agent, and cleaning; S6, putting the thermal element plate into a clean water tank to remove the residual cleaning agent; and S7, drying moisture on the thermal element plate through a drying machine, and taking out the thermal element to complete machining. The production process has the beneficial effect that impurities and oil stains attached to the thermal element plate can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of circuit breaker accessories, in particular to a production process for a thermal element of a circuit breaker. Background technique [0002] At present, the circuit breaker thermal tripping device on the market is composed of bimetal, heating element, draw bar and other components. When the rated current flows through the heating element or bimetal, after a period of time, the bimetal directly heats up and bends or induces the heating element The heat is bent, and then the drawbar is pushed by adjusting the adjusting screw set on the bimetal sheet, so that the operating mechanism is tripped, the circuit breaker is broken, and the overload protection of the line is realized. [0003] During the manufacturing process of existing heating elements, various oil stains and impurities are generally attached to their outer surfaces. If they cannot be cleaned, the conductivity of the heating elements will be affec...
