Hydraulic Guillotine Shearing Machine Components
A hydraulic guillotine shearing machine consists of several essential components that work together to deliver precise metal cutting performance.
Frame Structure
The machine's backbone made of welded steel with reinforced ribs or box-type designs to withstand cutting forces and prevent deformation. Includes a rigid bed (lower part) and crown (upper part) for stability.
Hydraulic System
The power source that drives the machine's operations:
| Component | Function |
|---|---|
| Hydraulic Pump | Converts electrical to hydraulic energy |
| Cylinders | Drive blade motion and adjustments |
| Valves | Control oil flow and pressure |
| Reservoir | Holds fluid and dissipates heat |
Cutting Blade Assembly
- Upper Blade: Moves with ram, made of hardened tool steel (HRC 55-60)
- Lower Blade: Fixed to bed with rotatable edges
- Blade Gap Adjustment: Screw-type or hydraulic mechanisms for material-specific settings
Backgauge System
Ensures accurate sheet positioning with gauge fingers, drive mechanisms (manual/motorized/CNC), and precision feedback via linear scales or digital readouts (DRO).
Clamping Device
Hydraulic or mechanical toggle clamps secure the sheet during cutting to prevent movement and ensure safety and accuracy.
Electrical Control System
- PLC: Controls hydraulic operations and safety interlocks
- HMI: Touchscreen/button interface for parameter input
- Safety Circuits: Emergency stops, light curtains, overload protection
Safety Note:
Always follow manufacturer guidelines for maintenance and operation. Ensure all safety devices are functional before use.
Guiding & Lubrication
Linear rails/gibs maintain ram alignment while automatic lubrication systems reduce wear on moving parts.
Understanding these components helps operators maintain optimal performance and safety in hydraulic guillotine shearing operations, ensuring precise cuts and extended machine lifespan.
