Description

Technical Field

[0001] The utility model relates to the technical field of fuse processing, in particular to a fuse pressing structure. Background Art

[0002] Ceramic tube fuses are made of ceramic materials and have high electrical strength and heat resistance. They use ceramic powder pressing and high-temperature sintering processes to create a fuse structure with a specific shape and specifications. Its manufacturing process includes raw material preparation, batching, pressing, sintering, processing, testing and other steps. It is widely used in electronic equipment, household appliances, communication equipment, power equipment and other fields as circuit protection components to prevent fires or equipment damage caused by current overload.

[0003] Due to structural limitations, ceramic tube fuses cannot be pressed simultaneously at both ends during the zinc sheet fuse pressing operation. Instead, one side must be pressed first, followed by the other. The previous method involved placing the product into a pressing jig, then operating the pressing mechanism to press one side. After completion, the product was removed from the pressing jig, rotated 180°, and placed back into the pressing jig, where the pressing mechanism was operated to press the other side. While this method can still complete the pressing operation, it is laborious and time-consuming, resulting in low work efficiency. Furthermore, workers experience high fatigue levels, making it easy for them to mistakenly press the already pressed side of the product again, resulting in defective products and increased production costs. Therefore, a fuse pressing structure is needed to improve the above-mentioned issues. Utility Model Content

[0004] The purpose of the utility model is to provide a fuse pressing structure, aiming to solve the above technical problems.
