Features
Special numeric-control system is fitted with mainframe of the bending machine.
Multi-work-step programming function is able to achieve an automatic operation and continuous positioning of multi-step procedures, as well as an automatic precision adjustment for positions of rear stopper and gliding block.
The machine is provided with bend counting function, for a real-time display of processing quantity and power-failure memory of positions of stopper and gliding block, as well as procedures and parameters.
Imported ball bearing lead screw and linear guide rail are used for rear stopper, to ensure the positioning precision of rear stopper, for processing precision of machine to be higher.
A press brake is a machine tool used in sheet metal bending and forming processes. It's a crucial piece of equipment in manufacturing and metalworking industries, allowing for the precise bending of sheet metal to create various shapes and angles. The process involves applying force to a workpiece placed on a die to bend it along a straight axis.
Here are the main components and features of a press brake:
Frame: The frame provides the structural support and rigidity for the entire press brake. It's designed to withstand the high forces involved in the bending process.
Bed and Ram: The bed is the flat surface where the lower die is mounted, and the ram is the moving upper part that applies the bending force to the workpiece against the die.
Hydraulic or Mechanical Systems: Press brakes can be operated using hydraulic or mechanical systems. Hydraulic press brakes use hydraulic cylinders to generate force, while mechanical press brakes use a motor and mechanical linkage.
Hydraulic System: In hydraulic press brakes, hydraulic cylinders and a hydraulic pump generate the force needed for bending. The pressure is controlled and regulated to achieve precise bends.
Die: The die is a specially shaped tool that determines the bend angle and shape of the workpiece. The workpiece is placed between the die and the ram for bending.
Backgauge: The backgauge is a mechanism that holds and positions the workpiece accurately for consistent bends. It can be manually adjusted or controlled using computer numerical control (CNC) for automated operations.
Control Panel: The control panel allows operators to set bending parameters such as the desired bend angle, material thickness, and backgauge position. Modern press brakes often use CNC controls for precise and automated bending processes.
Foot Pedal or Controls: Operators use foot pedals or controls to initiate and control the bending process. The foot pedal allows for hands-free operation, which is especially useful during setup and alignment.
Press brakes come in various sizes and capacities to accommodate different workpieces and bending requirements. They can bend a wide range of materials, including steel, aluminum, and stainless steel, with varying thicknesses.
The bending process involves clamping the workpiece between the die and ram, applying force to achieve the desired bend angle, and then releasing the force to remove the bent workpiece.
Safety measures, operator training, and adherence to safety protocols are crucial when operating a press brake to ensure the safety of the operators and the proper functioning of the equipment.
