A bending machine is a specialized mechanical equipment used for bending and forming metal sheets. It uses the combination of upper and lower molds to bend the metal sheet placed on the workbench to produce parts that meet specific requirements. The working principle of a bending machine involves using a hydraulic system to generate pressure, which is transmitted through a mold to ultimately obtain the desired material shape.
Main components and working principle
The main components of a bending machine include a bracket, worktable, clamping plate, upper mold, lower mold, and hydraulic system. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate through a hinge to clamp the metal sheet. The hydraulic system applies electricity to the coil through wires, generating attraction and achieving clamping of the sheet metal. During the processing, the upper mold descends and closes with the lower mold, completing the bending of the sheet metal.
Classification and Characteristics
Bending machines can be divided into manual bending machines, hydraulic bending machines, and CNC bending machines according to their operation methods and control systems. Manual bending machines are divided into mechanical manual bending machines and electric manual bending machines. Hydraulic bending machines can be divided into torsion axis synchronization, machine hydraulic synchronization, and electro-hydraulic synchronization according to synchronization methods, and can be divided into upward and downward movement types according to motion methods. The CNC bending machine is operated through a computer numerical control system and has the characteristics of suitable accuracy and good efficiency.
Structural characteristics
The structural characteristics of the bending machine include the use of a fully welded steel structure to provide sufficient strength and rigidity, a hydraulic transmission system that directly drives the slider to move up and down, a slider synchronization mechanism that uses torsion axis forced synchronization, and a mechanical block structure to confirm stable and excellent operation. In addition, the bending machine is equipped with a deflection compensation mechanism and the function of adjusting the stroke at a suitable speed to improve machining accuracy and operational convenience.
Usage and maintenance
When using a bending machine, it is necessary to first connect the power, adjust the stroke, select the appropriate bending slot, adjust the rear stopper, and start the bending operation by stepping on the foot switch. In terms of maintenance, it is necessary to regularly check the hydraulic oil level, clean hydraulic components, replace or clean filters, and check whether there is deformation at the bend of the oil pipe to confirm the normal operation of the equipment and extend its service life.
Application industry
Bending machines are widely used in the metal processing industry, including steel structures, automobile manufacturing, elevators, railway vehicles, and other industries. Focusing on CNC bending machines, due to their accurate and efficient processing capabilities, they are particularly suitable for the production of complex and delicate metal parts. With the development of technology, CNC bending machines have also demonstrated good adaptability and flexibility, which can meet diverse processing needs
