Hydraulic PPGI/PPGL Sheet Bending Machine
A hydraulic bending machine primarily comprises a support structure, a worktable, and a clamping plate. The worktable, which is securely positioned on top of the support, is an assembly of a base and a pressing plate. These components work in tandem to form the core working area of the machine. The base is ingeniously connected to the clamping plate via a hinge, enabling a pivotal movement that is essential for the clamping operation.
The base itself has a sophisticated internal construction, consisting of a housing, a coil, and a cover plate. The coil, a crucial element for the clamping mechanism, is precisely placed within the recess of the housing. This recess is then sealed with a cover plate, providing protection and ensuring the proper alignment of the coil.
During operation, an electric current is passed through the wires connected to the coil. Once energized, the coil generates a powerful electromagnetic field that exerts an attractive force on the pressing plate. This electromagnetic force effectively clamps thin plates firmly between the pressing plate and the base, creating a stable and secure working environment.
One of the significant advantages of using electromagnetic force for clamping is the flexibility it offers in workpiece design. The pressing plate can be customized to meet a wide range of specifications and requirements of different work pieces. Additionally, this clamping method allows for the processing of workpieces with side walls, expanding the machine’s capabilities and versatility in various manufacturing applications.
Advantages of Bending Machine
1. Structural Design of bending machine
Adopts fully welded all-steel construction, with stress relieved by vibration aging treatment to eliminate internal stresses, ensuring long-term structural stability and preventing deformation.
2. Mechanical Performance
– High-strength and rigid frame design ensures minimal deflection during heavy-duty bending operations, maintaining precision over prolonged use.
– Top-mounted hydraulic drive system provides smooth, stable power transmission with low noise, enabling consistent bending force and reliable operation.
3. Human-Machine Interface
– Multi-level LCD Chinese menu display with a user-friendly interactive interface, offering intuitive operation and quick parameter adjustment. The interface supports real-time process monitoring and error diagnosis for enhanced usability.
4. Program Storage & Processing Capability
– Ultra-large memory capacity allows storage of over 100 programs, each program supporting 100 processing stations. Each station can execute up to 100 cycles, suitable for complex batch production and multi-step forming processes.
5. Control Precision & Functions of bending machine
– Semi-automatic and manual operation modes with repeat positioning accuracy ≤0.10mm and control accuracy reaching 0.10mm, meeting high-precision bending requirements for sheet metal parts.
– Bidirectional and unidirectional positioning functions, combined with lead screw clearance compensation (for frequency conversion versions), eliminate cumulative errors and ensure consistent positioning precision.
– Automatic retraction function of the rear stop device (for frequency conversion versions) avoids interference with work pieces, further improving positioning accuracy and preventing damage during operation.
