Description

Technical Field

[0001] This utility model relates to the field of fuse processing technology, and in particular to a multi-station pressing structure. Background Technology

[0002] Ceramic tube fuses are fuses made of ceramic materials, possessing high electrical strength and heat resistance. They are manufactured using processes such as ceramic powder pressing and high-temperature sintering to produce fuse structures with specific shapes and specifications. The manufacturing process includes steps such as raw material preparation, batching, pressing, sintering, processing, and testing. They are widely used in electronic equipment, home 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 two points during the zinc sheet crimping process. The traditional crimping method involves placing a single product in a fixture, using a pressing device to crimp one side, then rotating the product 180° before placing it back into the fixture to crimp the other side. This crimping process is inefficient, impacts processing speed, and cannot meet the rapid delivery requirements of bulk orders. Therefore, a multi-station crimping structure is needed to improve upon these issues. Utility Model Content

[0004] The purpose of this invention is to provide a multi-station pressing structure to solve the aforementioned technical problems. This invention uses five identical pressing pins on an upper mold fixing plate and a movable bottom mold below it. The movable bottom mold has five corresponding positioning grooves. When the pressing pins move downward, they can simultaneously press the same end of five products. Then, the pressing pins are lifted, and the movable bottom mold is moved to the corresponding position. At this time, the pressing pins press downward again to complete the pressing of the other end of the five products. This achieves the goal of completing multiple identical tasks in one action, thus improving work efficiency.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A multi-station pressing structure includes a frame, on which a pressure pin assembly and a bottom mold assembly are mounted. The pressure pin assembly is located above the bottom mold assembly. The bottom mold assembly includes a base plate, a fixed bottom mold, a movable bottom mold, and a fixing rod. The base plate is detachably mounted on the frame, and its upper end is connected to the fixed bottom mold. The fixed bottom mold has a movable groove, and the movable bottom mold is movably mounted in the movable groove. The fixing rod is rotatably mounted on the movable bottom mold. The movable bottom mold has several positioning grooves for placing products.

[0007] Preferably, the pressure needle assembly includes a control device, an upper mold fixing rod, an upper mold fixing plate, and a plurality of pressure needles. The control device is mounted on the frame, and the output end of the control device is connected to the upper mold fixing rod. The lower end of the upper mold fixing rod is connected to the upper mold fixing plate, and a plurality of pressure needles are mounted on the upper mold fixing plate.

[0008] Preferably, the control device is equipped with a pressure rod, and operating the pressure rod can drive the upper mold fixing rod to move up and down, thereby driving the pressure needle to perform up and down pressing motion.

[0009] Preferably, the movable bottom mold is provided with a rotating shaft and a fixing hole. The lower end of the rotating shaft is located in the fixing hole, the upper end of the rotating shaft is connected to a fixing rod, and one end of the fixing rod is rotatably connected to the movable bottom mold through the rotating shaft.

[0010] Preferably, the fixed bottom mold is provided with a plurality of limiting corner grooves and a plurality of first assembly holes, the limiting corner grooves are connected to the movable grooves, and the first assembly holes are located on one side of the limiting corner grooves.

Its overall processing is simple, with few components, avoiding the use of complex structures, and is convenient to install and disassemble, reducing manufacturing costs and facilitating widespread production.

[0016] 2. High work efficiency: This utility model features a multi-station pressing structure. In use, five products are first placed in the positioning grooves. The fixing rod is rotated to secure the products in the grooves. Then, the pressure rod is pressed down, causing the pressure needle to move downwards and press the same end of the products. The pressure rod is then lifted, and the operator moves the movable bottom mold to the corresponding position in the movable groove. The pressure rod is then pressed down again, and the pressure needle presses downwards again, completing the pressing of the other ends of the five products. By employing identical, simple, and repetitive processes, one action completes multiple identical tasks, improving work efficiency, reducing labor costs, and shortening the product manufacturing cycle. This allows for faster order fulfillment and demonstrates strong practicality. Attached Figure Description
