Below is the standardized official operation instruction for the YWC Cold Heading Machine for Rivet and Small Screw Manufacturing. This complete operation guide covers pre-operation inspection, intelligent parameter debugging, formal production procedures, standardized shutdown processing and daily safety specifications, enabling users to achieve standardized, safe and high-efficiency micro fastener production with this automatic rivet forming machine.
Before starting the YWC cold heading machine for rivet and small screw production, complete comprehensive pre-operation inspection to effectively avoid equipment failure and defective micro fastener products:
Mechanical Inspection: Check whether the machine body bolts, dies, transmission parts and feeding wheels are loose or worn. Ensure the forming die for small screws and rivets is installed firmly without offset. Clean iron scraps and sundries inside the forming cavity to guarantee micro fastener forming accuracy.
Oil & Circuit Inspection: Check the lubricating oil and hydraulic oil volume to ensure sufficient oil supply. Inspect the circuit connection for safety and no virtual connection. Confirm the cooling system works normally to prevent overheating during high-speed continuous operation.
Material & Die Matching Check: Select matched dies according to the size of produced rivets and small screws. Confirm the raw material wire diameter matches the equipment specification, avoid using mismatched materials to prevent die damage and product deformation.
Equipment Level Inspection: Verify the machine is placed horizontally and fixed stably to prevent vibration deviation during high-speed cold heading, which affects the precision of tiny rivets and small screws.
Equipped with YWC intelligent PLC control system, this small screw manufacturing machine supports precise and flexible parameter adjustment, perfectly adapting to different sizes and material types of rivets and small screws:
Turn on the equipment power, enter the PLC control interface, and select the corresponding production mode: rivet forming mode or small screw forming mode.
Set production parameters including feeding length, cutting stroke, cold heading pressure and production speed according to product specifications. For micro rivets and ultra-small screws, appropriately reduce the operating speed to ensure precise forming.
After parameter setting, save the data. The system supports multi-group parameter memory, which can be called directly for repeated production of the same specification, greatly improving debugging efficiency.
Perform 3-5 times of no-load jogging debugging to confirm the equipment runs smoothly without jamming, abnormal noise or die collision.
Adhere to the following standardized operation steps for stable batch manufacturing of rivets and small screws with the YWC high precision cold heading equipment, ensuring consistent product precision and high production yield:
No-load Test Run: After debugging, start the no-load automatic operation mode, let the machine run stably for 5 minutes, observe the coordination of feeding, cutting and heading actions, and confirm no abnormal failure.
Sample Trial Production: Put in raw materials for trial production of 10-20 samples. Check the rivet head shape, screw head flatness, size tolerance and surface finish. Fine-tune parameters slightly if there is minor deviation until the samples fully meet the standard.
Official Mass Production: After the samples are qualified, start formal automatic batch production. The equipment will automatically complete wire straightening, fixed-length cutting, one-time cold heading forming and finished product discharging.
Real-Time Production Monitoring: During continuous production, regularly check the finished product quality every 10 minutes. Observe the equipment operating status to ensure stable feeding and accurate forming, avoid batch defective products.
Standard shutdown cleaning and daily maintenance are essential to stabilize the performance and extend the service life of the YWC Cold Heading Machine for Rivet and Small Screw Manufacturing, ensuring long-term stable precision of micro fastener forming:
Stop the feeding system first, continue the equipment idle running for 2-3 minutes to completely discharge the residual raw materials and scraps inside the machine.
Cut off the equipment power and air source, clean the forming die cavity, feeding channel and discharging port thoroughly to remove accumulated iron scraps, preventing die wear affecting next use precision.
Lubricate the transmission bearings, guide rails and moving parts to ensure flexible mechanical operation for the next production.
Arrange the production site, cover the equipment dust cover if it is shut down for a long time, and complete daily operation records.
Professional trained operators are required for equipment operation. It is forbidden for non-professionals to adjust parameters or disassemble the machine arbitrarily.
It is strictly prohibited to put hands or tools into the die working area during equipment operation to avoid mechanical safety accidents.
Do not overload the machine for a long time. Appropriately reduce the speed when producing ultra-small rivets and thin screws to ensure stable forming quality.
In case of material jamming, abnormal noise or equipment failure during production, press the emergency stop button immediately, cut off the power supply for troubleshooting, and forbidden forced startup.
Regularly check die wear degree every week, replace worn dies in time to ensure the dimensional accuracy of rivets and small screws.
