Steel Bar Straightening Machine Operating Instructions
Select the Right Settings:
Choose the appropriate straightening block, traction pulley groove, and transmission speed based on the steel bar diameter.
Ensure the straightening block hole diameter is 2~5mm larger than the steel bar diameter, and the traction pulley groove width matches the steel bar diameter.
Adjust Straightening Blocks:
Place the first and fifth straightening blocks on the center line, while the middle three can deviate.
Initially offset steel bars by about 3mm. Gradually increase the offset if bars remain bent until straightened.
Check Length:
After cutting three or four steel bars, stop the machine to verify the length. Adjust the limit switch or sizing plate if necessary.
Install Guide Pipe:
Insert a 1-meter steel bar in front of the guide pipe to prevent bars from popping out during straightening.
Ensure steel bars pass through the steel pipe before entering the guide tube and straightening tube.
Safety Measures:
Do not penetrate steel bars before fixing straightening blocks and properly covering the protective cover.
Prevent straightening block ejection by ensuring proper cover placement before starting the machine.
Safety Precautions:
Avoid stacking objects on the machine to prevent vibration-induced items from falling into the machine.
Maintain a safe distance between hands and pressure roller when loading steel bars.
Do not adjust the roller while the machine is running, and refrain from wearing gloves during operation.
Safety Guidelines:
Keep personnel away from the machine when steel bars are straightened to prevent injury.
Process steel bars shorter than 2m or with a diameter over 9mm at low speed to ensure safety.
Safety Operating Procedures for Steel Bar Cutting Machines
Ensure Safe Operation:
Only cut materials when the machine is running normally.
Maintain a minimum distance of 15cm between hands and the knife edge during cutting.
Never feed material while the movable blade is in motion.
Adhere to Load Limits:
Avoid cutting steel bars that exceed the machine’s load capacity.
For special steel bars like low alloy steel, use high hardness blades for cutting.
Handle Long and Short Bars Appropriately:
Support long steel bars during cutting operations.
Maintain consistent movements and use appropriate tools like casing or pliers to clamp short bars.
Refrain from feeding material directly by hand for short bars.
Ensure Personnel Safety:
Do not manually remove short ends or debris near the knife edge during machine operation.
Non-operators should stay clear of the steel bar swing area and knife edge.
Post-Work Cleanup:
Thoroughly clean the workspace after completing the task to prevent hazards.
Safety Operating Procedures for Steel Bar Bending Machines
Prior to Use:
Ensure proper grounding during mechanical installation to prevent electrical hazards.
Avoid direct power connection to buttons; use an additional iron-cased switch control power supply.
Pre-Operation Checks:
Verify completeness of machine parts and proper selection of moving gear for steel bar diameter.
Confirm machine speed consistency and appropriate gear meshing gap.
Ensure tightness of fixed iron wedges and proper turntable direction.
Lubricate according to regulations and inspect electrical equipment grounding wire.
Conduct trial operation to ensure qualification before proceeding.
Safe Operation:
Securely position the steel bar end needing bending between the fixed hoes on the turntable.
Keep the other end close to the fuselage fixed hoe, pressing it with one hand.
Confirm correct installation of the fuselage hoe on the side holding the steel bar before starting the machine.
Hoe Replacement:
Replace turntable fixed hoes only after stopping the operation.
Safety Guidelines:
Avoid bending steel bars exceeding the specified diameter and using hooks not rated for lifting.
Wear protective glasses when bending non-cold drawn or rusty steel bars.
Adjust maximum diameter for non-ordinary steel bars like low alloy steel according to machinery nameplate regulations.
Transmission Gear Installation:
Use fast gears for steel bars less than 18 mm in diameter.
Employ medium-speed gears for diameters between 18 to 24 mm.
Utilize slow gears for diameters above 25 mm.
Operational Caution:
Reverse turntable only after previous steering has stopped.
Wait for the car to stop in the middle gear before changing direction; avoid immediate reverse gear adjustment.
Immediately cut power and stop machine if chuck vibrates excessively or motor overheats.
Safety Measures:
Keep clear of rotating steel bars and fuselage radius without fixed hoes.
Stack bent semi-finished products neatly; avoid turning up hooks.
Handling Long Steel Bars:
Assign dedicated personnel to assist in handling long steel bars.
Assist personnel should follow operator’s commands and not push arbitrarily.
Post-Operation Cleanup:
Clean workplace and machine; use manual air blower to remove rust accumulation in seam pits, avoiding finger contact.
