Safety Operating Procedures for GHM Machinery Steel Bar Machines

Steel Bar Threading Machines:

1. Designate a dedicated operator for equipment management.
2. Adhere strictly to safety procedures for tapered thread threading machines.
3. Ensure thorough understanding of the structure, principles, and performance of the machine.
4. Maintain focus during operations; avoid laughter or playful behavior.
5. Before use, conduct comprehensive equipment and electrical inspections to identify and eliminate hazards.
6. Securely clamp the steel bar during threading to prevent injuries.
7. Implement effective cooling and safety measures to prevent splashing of iron filings.
8. Never clean dust or debris from blades during operation; halt machine for inspection and repair if necessary.
9. Avoid operating the machine beyond its specified performance limits.
10. Follow the “cross operation method” to ensure machine functionality.
11. Prohibit maintenance and repair work without halting machine operation.
12. After completing work, power down the machine and lock the gate box.

Steel Bar Straightening Machines:

1. Wear safety helmets, gloves, and rubber-soled shoes while operating.
2. Check machine stability, secure installation, and integrity of all components before use.
3. Restrict access within 2m of the machine’s sides during operation; install guardrails and safety signs.
4. Use proper lifting techniques with two-person cooperation when handling coiled steel.
5. Limit straightened steel bar length to 10m maximum per operation.
6. Select appropriate straightening blocks and traction wheel grooves based on steel bar diameter.
7. Adjust straightening blocks as needed; ensure proper alignment and offset.
8. Regularly inspect steel bar length after cutting; adjust length plate or limit switch as necessary.
9. Use a steel pipe before final straightening to prevent steel bar ejection.
10. Ensure fixed straightening blocks and closed protective covers before starting machine; implement dust prevention measures during operation.
11. Maintain safe distance from traction wheel during operation.
12. Monitor bearing temperature; stop machine if temperature exceeds 60℃.
13. Restrict non-essential personnel near the machine during operation.
14. Prevent steel bar ends from causing injury as coils are depleted.
15. Immediately report abnormal conditions to maintenance team; refrain from unauthorized maintenance.
16. Power down machine and lock switch box after operation or power outage.

Steel Bar Cutting Machines:

1. Ensure work surface aligns with cutter; use additional personnel for longer steel bars.
2. Inspect cutter for cracks, tighten blade holder bolts, and secure protective covers before starting.
3. Conduct empty run to check transmission and bearings before operation.
4. Use middle and lower parts of cutter to securely feed steel bars; stand beside fixed blade during operation.
5. Do not cut steel bars exceeding machine specifications; calculate total cross-sectional area when cutting multiple bars.
6. Replace with high-hardness cutter when cutting low-alloy steel.
7. Maintain safe distance from blade during short material cutting.
8. Avoid manual removal of debris during operation; keep non-operating personnel away from swinging steel bars.
9. Stop machine immediately if abnormal sounds or conditions arise; power down and report to maintenance team.
10. Check hydraulic oil level and motor rotation direction before operating hydraulic cutting machines; release oil valve and exhaust air from hydraulic cylinder.
11. Ensure proper valve settings before using manual hydraulic cutting machines; wear insulating gloves during operation.
12. Clean and lubricate machine; power down after operation.

Steel Bar Bending Machines:

1. Ensure level workbench and machine table; prepare necessary mandrels and tools.
2. Install mandrels and forming shafts according to steel bar diameter and bending radius requirements.
3. Verify integrity and firm installation of mandrels, iron stop shafts, and protective covers before operation.
4. Conduct idle run to confirm normal operation before bending steel bars.
5. Insert steel bar ends into appropriate positions; use assistance for longer bars; avoid unnecessary pushing or pulling.
6. Do not alter mandrels, pins, angles, or perform maintenance during operation.
7. Wear protective glasses when bending rusted or non-cold-drawn steel bars.
8. Adhere to machine specifications when bending high-strength or low-alloy steel bars.
9. Maintain safe distance from machine body during operation; stack bent products securely.
10. Do not exceed maximum diameter specified on machine nameplate.
11. Perform maintenance or turntable reversal only after powering down machine.
12. Clean debris from turntable and seat holes after operation.
