Three-Roller Plate Bending Machine Operation Guide
Operation guide for 3-roller plate bending machines covering equipment overview, pre-startup inspection, 7-step operation, maintenance and safety.
# Three-Roller Plate Bending Machine Guide
## Overview
A three-roller plate bending machine is critical equipment for metal sheet forming, used to roll flat plates into cylindrical, arc, and conical shapes.
## Working Principle
Three points define a circle. The metal sheet undergoes continuous plastic deformation under three rollers.
## Pre-Startup Inspection
- Check roller surfaces free of dents and cracks
- Check hydraulic oil level normal
- Verify emergency stop button functional
## Operation Procedure
1. Connect main power supply
2. Perform no-load jog test
3. Place sheet smoothly into equipment
4. Start roller rotation and adjust side rollers
5. Confirm rollers stopped before unloading
## Maintenance
- Daily: clean roller surfaces, check oil circuits
- Weekly: check fasteners, inspect lubrication
- Monthly: check hydraulic oil, inspect filter elements
