How to maintain an automatic riveting machine daily? Maintenance items, cycle and common fault prevention
An automatic riveting machine is not structurally complex, but its feed channel is precise and it runs continuously at high frequency; standardized maintenance clearly lowers the jam rate and extends the life of the gun body and wear parts. BISUDI complete machines pass a 30,000-cycle continuous riveting test without jamming, with a long-term fault rate of about 0.3%, and a large part of that comes from customers doing daily maintenance by the book. This article gives a directly executable maintenance checklist.
I. Maintenance items and cycle
| Cycle | Maintenance Item | Key Point |
|---|---|---|
| Each shift/daily | Clean the nozzle, jaws, nail-receiving port and equipment surface | Remove rivet debris, oil and dust, keeping the feed channel clean |
| Daily | Check the air source | Drain water from the filter, confirm stable air pressure, and ensure air tubes are undamaged and leak-free |
| Weekly | Lubricate moving parts | Apply the specified lubricant to sliding and moving parts per the manual |
| Weekly | Check the vibratory bowl/hopper | Clear foreign matter from the bowl, confirm smooth sorting and sensitive sensors |
| Monthly | Check wear parts | Wear status of nozzle, jaws and ejector pin, replaced promptly |
| Quarterly | Comprehensive inspection | Tighten screws, check seals and electrical wiring, verify counting and alarm |
II. Key-part maintenance points
Nozzle and jaws.These directly contact the rivet, and slight metal adhesion can appear when processing certain materials; clean them regularly to prevent thickened adhesion from affecting grip and break-off; over-worn jaws slip and cannot grip the mandrel and must be replaced promptly.
Feed channel and vibratory bowl.After switching rivet specifications, thoroughly clear the channel to prevent mixed rivets jamming the tube; keep the vibratory bowl dry and oil-free, wipe sensor surfaces periodically, and avoid false missing-nail judgments.
Air circuit system.Drain accumulated water from the air compressor and filter cup daily; insufficient air pressure causes weak feeding and incomplete riveting; avoid bending or crushing air tubes and promptly fix leaking fittings.
III. Common faults and prevention
| Symptom | Common Cause | Action/Prevention |
|---|---|---|
| Jamming, incomplete feeding | Foreign matter in channel, mixed-spec material, worn nozzle | Clear the channel, empty leftover rivets after spec change, replace the nozzle |
| Mandrel won't break/rivet loose | Insufficient air pressure, worn jaws, pulling-force mismatch | Check air pressure, replace jaws, verify rivet against model |
| Missed rivet, dry fire | Dirty sensor, nail-separation cycle drift | Clean the sensor, re-debug nail separation |
| Workpiece scratches | Metal adhesion on nozzle, operation alignment deviation | Clean the nozzle, standardize operation, add a protective sleeve |
IV. Recommendations for building maintenance habits
Turn "daily cleaning, weekly lubrication, monthly wear-part check" into an inspection sheet with named responsibility, and keep wear parts (nozzle, jaws, ejector pin) in stock by usage to avoid line stoppage from purchasing only after failure. BISUDI wear parts are supplied long term at cost, and the manufacturer can provide on-site maintenance guidance, operation training and fault handling, with novices able to take post after short training. For more systematic parts and after-sales notes seeAutomatic Riveting Machine Maintenance and Parts Supply Guide。
V. Daily inspection sheet (can be printed directly)
| Frequency | Inspection Content | Pass/Fail |
|---|---|---|
| Before shift | Whether air pressure is up to standard, nozzle and jaws are clean, and no-load feeding is smooth | [ ] OK [ ] Action |
| After shift | Empty leftover rivets, clean the gun head and nail-receiving port, shut off air and power, tidy the feed tube | [ ] OK [ ] Action |
| Weekly | Oil moving parts, clean the vibratory bowl, wipe sensors, check air-tube fittings for leaks | [ ] OK [ ] Action |
| Monthly | Check nozzle/jaw/ejector-pin wear, tighten screws, electrical wiring and alarm function | [ ] OK [ ] Action |
Spare-part advice: keep 1-2 sets of matching-spec nozzles and jaws in stock by nozzle wear degree, doubled for two-shift or high-cycle lines; if a single piece shows continuous anomalies (such as repeated jamming at the same position), stop and inspect first rather than running with a fault, to avoid damaging the gun body and workpiece. For faults you cannot clear yourself, keep a fault video and contact the manufacturer, which significantly shortens remote diagnosis time.
Maintenance FAQ
Maintenance FAQ
Just carry out the daily/weekly/monthly inspections in the table above; two-shift and high-cycle lines should double the frequency of lubrication and wear-part checks.
First cut power and air, and remove the rivet from the observation port per the manual; frequent jamming is mostly spec mismatch or part wear, so contact after-sales rather than repeatedly forcing it open.
The manufacturer serves nationwide and can be booked for on-site troubleshooting, maintenance and part replacement, with response time agreed in the service agreement.
The manual marks the recommended lubricant model and wear-part specifications, and arbitrary oil substitution is not advised; consumables can be purchased directly from the manufacturer at cost to avoid jams from spec mismatch.
Nationwide customers: need maintenance guidance or parts quotation
Wear parts supplied long term at cost; on-site maintenance and training can be booked, consultation hotline +86 13556668682.
