Overall, finger brakes offer versatility, precision, user-friendliness, cost-effectiveness, efficiency, and safety, making them a preferred choice in many metal fabrication applications over other bending methods. Finger brakes are widely used in various industries due to their ability to perform precise and intricate bends on metal sheets. They provide accurate metal bending and forming capabilities for components such as brackets, panels, frames, structural parts, and piping systems, ensuring quality and precise assembly in various applications. Their applications range from manufacturing industries like automotive and aerospace (helping produce complex parts) to the construction industry (used for shaping metal frames and roof panels). The electronics industry also utilizes this tool for fabricating metal enclosures for various devices. Furniture manufacturers use it to create metal components, while artists use it for crafting intricate metal sculptures. Additionally, its role in rapid prototyping across different sectors and as an educational tool in vocational colleges emphasizes its versatility and importance in metal fabrication. The main advantage of a finger brake is its adaptability, particularly with a kit of different finger sizes. It can achieve various bending lengths and shapes, ranging from long straight bends to box and pan shapes. Fingers can be rearranged or even removed to achieve complex bends and folds that standard straight press brakes cannot accomplish. The finger brake mainly consists of manual finger brake, hydraulic finger brake, pneumatic finger brake, CNC finger brake, sheet metal brake, electric finger brake etc. Typically is hydraulic finger brake, a machine used in metal fabrication that utilizes hydraulic power to accurately bend and shape metal sheets. It is equipped with adjustable fingers or stops that aid in precise bending and folding operations. In a finger brake (also known as a box and pan brake), finger brake tooling is used to generate bends in specific areas of a workpiece, such as a metal sheet, without affecting the rest of the workpiece. The "fingers" are movable blocks that can be adjusted to accommodate different sizes and shapes of workpieces. When you need to perform a bend, you place the metal sheet on top of the fingers, arranging the fingers to match the desired bend. Then, the clamping bar descends, securing the workpiece in place. Next, the bending blade (essentially a flat part located underneath the workpiece) is raised, causing the metal around the fingers to bend. The key function of finger brake tooling is to achieve precise and intricate bends, which is particularly useful in creating boxes, pans, or other objects with specific shapes. A finger brake has different types of tooling, including V-dies, U-dies, hemming dies, and radius dies. Each type has a specific shape and purpose, allowing for a variety of bending possibilities. V-dies are commonly used and have a V-shaped groove that creates sharp bends in the metal. U-dies have a U-shaped groove and are suitable for making flanges or bending tubes with a slot. Hemming dies are designed for folding and overlapping metal edges, often used for seams or joining two pieces of metal together. Radius dies have a curved bending surface and are used to create bends with a specific radius. They are ideal for applications that require smooth, rounded bends. Choosing the appropriate tooling is crucial for achieving precise and desired bends. The selection depends on factors such as material type, thickness, required bending angle, and bending radius. Different tooling options have varying levels of precision, allowing for flexibility in creating different shapes and angles. Understanding the characteristics of different tooling and their compatibility with specific materials helps optimize the bending process, resulting in high-quality and consistent bends. A "finger brake kit" usually includes a variety of tools and components that are designed to be used with a press brake for the purpose of bending sheet metal. The exact contents can vary based on the specific kit and manufacturer, but commonly, these kits may include: Finger Dies: These are the main components of the kit and come in a variety of sizes to accommodate different bend lengths. They are shaped to allow for the bending of specific sections of a workpiece without affecting other areas. Mounting Hardware: This includes bolts, nuts, and other fasteners required to secure the dies and clamping bars to the press brake. Adjustment Tools: These may include wrenches or other tools used to adjust the position of the finger dies or clamping bars. Storage Case: Many kits also come with a case or box for storing and transporting the components. User Manual: Instructions on how to safely and effectively use the finger brake dies and other components in the kit. Press Brake Body: This is the main structure that supports the tooling and applies the force necessary for bending. Lower Die or Bending Die: This is the lower tooling element that the sheet metal is pressed against Support Equipment: Depending on the complexity of the kit, it might include additional equipment such as: Back Gauges: These are positioning tools that help ensure the workpiece is aligned properly for precise bends. Side Gauges: These help ensure that the workpiece is square to the bending line. Clamping Tools: These tools are used to hold the workpiece securely in place during bending. (1) Safety First: Always wear protective gear, including safety glasses, gloves, and steel-toed boots. Ensure the workspace is clean and free of debris. (2) Plan Your Bends: Determine the order of bending and mark the bending spots on the workpiece. (3) Align the Finger Dies: Arrange the finger dies on the upper beam based on the shape you want to bend. Align them according to your bending requirements. The fingers should correspond to the marked positions on the workpiece. (4) Material Placement: Place the metal sheet on the bending die, using the backgauge to ensure it is in the correct bending position. The side rule can help ensure the sheet is perpendicular to the bend line. (5) Bending: Once the workpiece is properly positioned, lower the upper beam to form the bend. Some bending machines are manually operated, requiring the operator to apply force, while others are hydraulic or electric, needing the operator to press a button or pedal. (6) Reposition for Further Bending: If multiple bends are needed, raise the upper beam, reposition the workpiece, and repeat the process. The finger dies allow for bending without interfering with existing bends. (7) Inspection: Always inspect the workpiece after the bending process to ensure the bend is correct and meets necessary specifications. (8) Shut Down the Machine: After completion, ensure the machine is correctly shut down and the workspace is clean. (9) Maintenance: Regularly maintain the machine, keeping it clean, lubricating moving parts, and checking tools for wear or damage. When using a finger brake, safety is of paramount importance.
