Used YANGLI 250T4000 Sheet Bending Machine For Sale

A Used YANGLI 250T4000 Sheet Bending Machine is a machine tool used in sheet metal fabrication to bend sheet metal into desired shapes. It works by pressing a punch (the upper tool) into a die (the lower tool), which forms the sheet metal into a predetermined shape. Here are some key components and features of a press brake:Used YANGLI 250T4000 Sheet Bending Machine

1. Rama: The frame of the press brake provides the structure and support for the bending operation. It’s typically made of heavy-duty steel to withstand the high forces involved in bending metal.Used YANGLI 250T4000 Sheet Bending Machine
2. Bed and Ram: The bed is the flat surface where the lower tool (die) is mounted, while the ram is the moving part of the press brake that holds the upper tool (punch). The ram moves up and down to apply force to the sheet metal, bending it against the die.
3. System hydrauliczny: Most modern press brakes use hydraulic systems to apply force to the ram. Hydraulic cylinders generate the necessary force to bend the metal accurately and efficiently. Hydraulic systems offer precise control over the bending process and can be adjusted for different materials and thicknesses.
4. Tylny ogranicznik: The backgauge is a device located behind the bending area that supports and positions the sheet metal accurately for bending. It ensures consistent bending angles and dimensions by controlling the depth of the bend.
5. System sterowania: Press brakes often feature a control system, which can be manual, CNC (Computer Numerical Control), or a combination of both. CNC press brakes allow for programmable bending sequences, precise positioning of the ram, and automatic adjustment of bending parameters, making them ideal for complex bending operations and high-volume production.Used YANGLI 250T4000 Sheet Bending Machine

Press brakes are widely used in industries such as automotive, aerospace, construction, and manufacturing, where sheet metal components are required for various applications. They come in a range of sizes and capacities to accommodate different sheet metal sizes and thicknesses, from small desktop models to large industrial machines capable of bending thick plates.
