In addition, its hinged design is convenient for reversal, disassembly, and maintenance, and is convenient to use.
[0026] Principle and advantages of use: By carefully setting up the bending die mechanism 2, the device can show excellent performance and convenient operation characteristics during use. Specifically, the driving motor 6 can be started to operate and its powerful power can be used to drive the transmission pulley 222 to rotate. It is worth noting that the transmission connection between each transmission pulley 222 is achieved through a transmission belt 223. When the transmission pulley 222 starts to rotate, it can drive the transmission belt 223 to rotate and move smoothly between the two transmission pulleys 222. At the same time, the transmission chain belt 224 is tightly connected to the transmission belt 223 through the fixing plate 225. As the transmission belt 223 moves, the transmission belt 223 can synchronously drive the bending die body 23 connected to the top of the transmission chain belt 224 to move. Since the bending die body 23 slides on the slide rail 21 through the sliding sleeve 226, as the transmission belt 223 moves, the bending die body 23 can be synchronously driven to perform precise displacement adjustment. During the adjustment process, the transmission pulleys 222 and the drive motor 6 on both sides are independently set. This unique design means that the bending die bodies 23 at both ends of the top of the bending machine side plate 1 can be independently movable and displaced without interfering with each other. This independence gives the equipment extremely high flexibility and adaptability, enabling it to be accurately adjusted according to different production needs and processing scenarios, greatly improving the overall production and processing adaptability of the equipment, thereby being able to meet diversified and complex production requirements, and providing a strong guarantee for efficient and high-quality production and processing.
