Key points of installation and use of Plate Rolling Machine
- The bending equipment is reliable grounding, lighting the safety voltage;
- Wedge, pin cannot give prominence to the surface;
- With the special tool with goggles.
- Parts installed firmly.
- Safety protection and protection device in time.
- Tail security bending device and material support frame.
- Selection of qualified grinding wheel, fitted with a reasonable card.
- Strengthen inspection, to eliminate the phenomenon of illegal wear and wear good labor protection supplies.
Three roll bending machines roll sheet metal to form curves.
When sheet metal is placed manually between the rollers, which must turn to secure the metal sheet, fixed or interlocked guards are impracticable. Plate metal thicker than approximately 6 mm will be placed by crane to prevent the operator from getting too close to the rollers, and to reduce the risk of manual handling injuries.
Hazards
- Trapping between rollers & metal
- Trapping between turning rollers
- Contact with sharp edges of metal
- Noise
- Slips, trips & falls
- Entanglement from unexpected movement (during maintenance, cleaning & repairs)
Personal protective equipment (PPE)
- Ear protection
- Eye protection
- Hand protection
- Tasks
- Task – Feed sheet metal through the rollers
- HAZARD
- Trapping between rollers & metal
- Trapped hands and fingers
- Crush injuries
- CONTROLS
- ENSURE safety devices are in places, such as an emergency stop wire or kick plate.
- ENSURE kick panels have a switch at each end.
- FIT emergency stop devices on both sides of the machine.
- HOLD workpieces back from the edge of the metal, allowing the metal to be fed into rollers without contact.
- ONLY WEAR gloves if they are fingerless.
- Sheet metal is usually placed by hand between the rollers, which turn together to pull the sheet through. As it passes between the rollers, the sheet curves to a diameter limited by the size of the rollers. The action that draws in a metal sheet can also draw in a hand. Finger ends of gloves can become entangled and draw fingers and hands into nips.
Task – Load & unload
HAZARD
Trapping between turning rollers & moving workpieces
HARM
- Trapped hands
- Crush injuries
- CONTROLS
- Operation MUST only occur when the machine is in the “run” position.
- COVER pedals to minimize the chance of accidental starts.
- FIT emergency stop devices.
- HAZARD
- Contact with sharp edges of metal sheets
HARM
- Cuts
- CONTROLS
- WEAR fingerless gloves to protect palms.
- Other (non-mechanical) hazards
- HAZARD
- Noise
HARM
- Hearing damage or loss
- CONTROLS
- REDUCE noise levels by isolating machines or enclosing within noise barriers.
- ASSESS noise levels.
- ARRANGE hearing screenings.
- ALWAYS WEAR hearing protection.
- A safe noise level over an eight-hour day is 85dB(A). A three-roll bending machine may exceed this noise intensity.
HAZARD
Slips, trips, and falls
- HARM
- Trapping
- Cuts
- Bruising
- CONTROLS
- KEEP up-to-date housekeeping procedures.
- KEEP the area around machines clear of slip and trip hazards.
- Task – Maintenance, cleaning & repairs
- HAZARD
- Entanglement from unexpected movement
HARM
- Trapped hands and fingers
- Crush injuries
- CONTROLS
- LOCK-OUT all power supplies before maintenance, cleaning, and repairs.
- KEEP written safety procedures, and ARRANGE regular safety inspections by a competent person.
- REMOVE or LOCK-OUT machines that fail inspection, and DO NOT USE until repaired or replaced.
