Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker shell processing, in particular to a circuit breaker shell deburring device. Background Art

[0002] Molded case circuit breakers can automatically cut off the current after the current exceeds the trip setting. The molded case refers to a plastic insulator used as the outer shell of the device to isolate the conductors and the grounded metal parts. At present, the shell of the molded case circuit breaker is formed by integral compression molding, which greatly reduces the process and saves the production cycle. The molded shell of the molded case circuit breaker is more beautiful and flat in appearance, and the weight is greatly reduced. At the same time, the integral compression molding process of the base improves the dimensional accuracy of the circuit breaker shell. After the molded shell of the circuit breaker is formed, in order to make the surface of the edge box smoother, the shell needs to be deburred.

[0003] When deburring, the existing deburring device often causes the removed debris to scatter on the ground due to the lack of a shield, which is inconvenient to clean and affects the workshop environment. In order to solve the above technical problems, the prior art proposes, for example, Chinese patent [application number CN202122368833.1] discloses a circuit breaker molded case deburring device, including a workbench, on which a blocking member is provided, the blocking member includes a first baffle and a second baffle, and the first baffle and the second baffle are fastened by a snap fastener; although the patent can set a blocking member on the deburring workbench and use the blocking member to block the debris, to a certain extent, reduce the debris scattering on the bottom surface, reduce the labor cost of cleaning, and maintain the workshop environment; however, the above patent has certain defects during use. For example, during the deburring process, the device can only partially reduce the scattering of debris, and the debris may splash out from above. The deburring process will also generate a certain amount of smoke and dust, which will cause certain harm if inhaled by the staff. Utility Model Content
