Steel Bar Threading Machines:
- Designate a dedicated operator for equipment management.
- Adhere strictly to safety procedures for tapered thread threading machines.
- Ensure thorough understanding of the structure, principles, and performance of the machine.
- Maintain focus during operations; avoid laughter or playful behavior.
- Before use, conduct comprehensive equipment and electrical inspections to identify and eliminate hazards.
- Securely clamp the steel bar during threading to prevent injuries.
- Implement effective cooling and safety measures to prevent splashing of iron filings.
- Never clean dust or debris from blades during operation; halt machine for inspection and repair if necessary.
- Avoid operating the machine beyond its specified performance limits.
- Follow the “cross operation method” to ensure machine functionality.
- Prohibit maintenance and repair work without halting machine operation.
- After completing work, power down the machine and lock the gate box.
Steel Bar Straightening Machines:
- Wear safety helmets, gloves, and rubber-soled shoes while operating.
- Check machine stability, secure installation, and integrity of all components before use.
- Restrict access within 2m of the machine’s sides during operation; install guardrails and safety signs.
- Use proper lifting techniques with two-person cooperation when handling coiled steel.
- Limit straightened steel bar length to 10m maximum per operation.
- Select appropriate straightening blocks and traction wheel grooves based on steel bar diameter.
- Adjust straightening blocks as needed; ensure proper alignment and offset.
- Regularly inspect steel bar length after cutting; adjust length plate or limit switch as necessary.
- Use a steel pipe before final straightening to prevent steel bar ejection.
- Ensure fixed straightening blocks and closed protective covers before starting machine; implement dust prevention measures during operation.
- Maintain safe distance from traction wheel during operation.
- Monitor bearing temperature; stop machine if temperature exceeds 60℃.
- Restrict non-essential personnel near the machine during operation.
- Prevent steel bar ends from causing injury as coils are depleted.
- Immediately report abnormal conditions to maintenance team; refrain from unauthorized maintenance.
- Power down machine and lock switch box after operation or power outage.
Steel Bar Cutting Machines:
- Ensure work surface aligns with cutter; use additional personnel for longer steel bars.
- Inspect cutter for cracks, tighten blade holder bolts, and secure protective covers before starting.
- Conduct empty run to check transmission and bearings before operation.
- Use middle and lower parts of cutter to securely feed steel bars; stand beside fixed blade during operation.
- Do not cut steel bars exceeding machine specifications; calculate total cross-sectional area when cutting multiple bars.
- Replace with high-hardness cutter when cutting low-alloy steel.
- Maintain safe distance from blade during short material cutting.
- Avoid manual removal of debris during operation; keep non-operating personnel away from swinging steel bars.
- Stop machine immediately if abnormal sounds or conditions arise; power down and report to maintenance team.
- Check hydraulic oil level and motor rotation direction before operating hydraulic cutting machines; release oil valve and exhaust air from hydraulic cylinder.
- Ensure proper valve settings before using manual hydraulic cutting machines; wear insulating gloves during operation.
- Clean and lubricate machine; power down after operation.
Steel Bar Bending Machines:
- Ensure level workbench and machine table; prepare necessary mandrels and tools.
- Install mandrels and forming shafts according to steel bar diameter and bending radius requirements.
- Verify integrity and firm installation of mandrels, iron stop shafts, and protective covers before operation.
- Conduct idle run to confirm normal operation before bending steel bars.
- Insert steel bar ends into appropriate positions; use assistance for longer bars; avoid unnecessary pushing or pulling.
- Do not alter mandrels, pins, angles, or perform maintenance during operation.
- Wear protective glasses when bending rusted or non-cold-drawn steel bars.
- Adhere to machine specifications when bending high-strength or low-alloy steel bars.
- Maintain safe distance from machine body during operation; stack bent products securely.
- Do not exceed maximum diameter specified on machine nameplate.
- Perform maintenance or turntable reversal only after powering down machine.
- Clean debris from turntable and seat holes after operation.
