Automatic Riveting Machine Operating Tips: Structure, Standard Operation, Maintenance and Fault Handling - BISUDI
Once the equipment is bought and taken back, whether it is used well depends half on selection and half on operation and maintenance. This article consolidates the structural understanding, operating method, continuous-work notes, maintenance cycle and fault handling in daily automatic-riveting-machine use into one piece, directly executable by workshop equipment owners and operators. This article covers general points; the manual shipped with the machine and on-site training content take precedence.
I. Structure and design logic of an automatic riveting machine
| Module | Function | Maintenance Focus |
|---|---|---|
| Vibratory bowl/hopper | Rivet sorting, orienting and nail separation | Clean inside the bowl, no deformed rivets mixed in |
| Blow-feed system (material tube) | Compressed air blows rivets to the gun head | Stable air pressure, no bent or leaking tubes |
| Rivet gun body | Gripping, pull-riveting, mandrel breaking | Wear status of nozzle, jaws and ejector pin |
| Control box | Parameters, counting, alarm | Sensor signals, firm wiring |
| Workbench/fixture | Workpiece locating (fixed) | Locating pins and pressing mechanisms not loose |
The design logic is "the main unit is responsible for delivering the correct rivet on time, the gun body for stably breaking it", so for jam-type faults first check the feed path, and for pulling-force faults first check air pressure and gun-body wear parts; segmented troubleshooting is fastest.
II. Standard operating method (beginner onboarding flow)
Step one, connect the air source and power and confirm air pressure is within the manual's specified range; step two, empty residual rivets in the tray and add rivets matching the nozzle spec, not over-filling at once; step three, fire a few no-load test rivets and listen whether the nail-separation, blow-feed and breaking rhythms are normal; step four, clamp the workpiece, seat the nozzle vertically against the hole and pull the trigger, moving the gun only after breaking; step five, after the shift empty leftover rivets, clean the gun head, and shut off air and power. BISUDI provides on-site installation, commissioning and training at delivery, and novices can take post after short training, as the operation itself is not hard; for details seeIs an Automatic Riveting Machine Hard to Operate? Beginner Onboarding and Training。
III. How does a pneumatic rivet gun achieve fast riveting?
The speed comes from the parallelization and compression of three links: first, the machine automatically sorts and feeds rivets, saving manual rivet threading and loading (the most time-consuming action in traditional manual work); second, compressed-air blow feeding delivers the rivet to the gun head with almost no waiting; third, one trigger pull of the gun body completes pull-riveting and mandrel breaking, at a cycle of about 80/minute. The worker only aligns and pulls the trigger, and one machine replaces the repetitive actions of about 3 riveting workers. The actual cycle must also count workpiece pick-and-place and repositioning time, so time by the complete workpiece rather than single-rivet speed; for the calculation method seeHow Many Rivets Per Minute and Capacity Calculation。
IV. Notes for continuous work
1) Ensure the air source: continuous high-cycle work uses much air, and insufficient compressor displacement and air storage makes riveting increasingly weak, so configure the pump per the manual and drain water periodically; 2) replenish the tray in time to avoid dry firing, and pick out deformed or burred rivets rather than mixing them in; 3) stop and inspect when the nozzle heats or makes abnormal noise, and do not run continuously with a fault; 4) about every 2 hours clean the gun-head nail-receiving port and check the jaws; 5) two-shift lines are advised to keep nozzles and jaws in stock as wear parts, minimizing unplanned line stoppage.
V. Daily inspection and maintenance (daily/weekly/monthly)
| Cycle | Item |
|---|---|
| Before shift | Check air pressure, nozzle/jaw cleanliness, no-load feeding and air-tube fitting leaks |
| After shift | Empty leftover rivets, wipe the gun head and nail-receiving port, shut off air and power, coil the feed tube |
| Weekly | Oil moving parts per the manual, clean the vibratory bowl, wipe sensors |
| Monthly | Check nozzle/jaw/ejector-pin wear, tighten screws, electrical wiring and alarm function |
Maintenance oil and wear-part specs follow the manual, and arbitrary oil substitution or non-matching nozzles are not advised; wear parts can be purchased from the manufacturer at cost.

VI. Common faults and handling methods
| Fault Symptom | Common Cause | Handling Method |
|---|---|---|
| Jam/no feeding | Deformed rivets, dirty/blocked channel, wrong nozzle spec | Stop and clear the channel, pick out bad rivets, change to a matched nozzle |
| Mandrel won't break | Low air pressure, worn/slipping jaws, nozzle not seated | Adjust air pressure, replace jaws, standardize gun-seating action |
| Insufficient force/loose rivet point | Insufficient air pressure, leaking air tube, worn ejector pin | Find the leak and restore pressure, replace worn parts, verify pulling force |
| Air leak/abnormal noise | Aged seal rings, loose fittings | Replace seal rings, tighten or replace fittings |
| Counting/alarm abnormal | Dirty or displaced sensors, loose wiring | Clean sensors, reset and fix, check wiring |
| Scratching workpieces | Bumped nozzle, poor vertical centering | Replace the nozzle, strengthen operation training, locate with a fixture |
For repeated jamming at the same position or persistently abnormal pulling force, stop first and keep a fault video, then contact after-sales for judgment, avoiding a small problem dragging into gun-body damage.

Use and Maintenance FAQ
Operation and Maintenance FAQ
Q1: How soon after a new machine arrives can it formally go into production?
Installation, commissioning and training are usually completed the same day, and production can start after a loaded trial with real workpieces confirms cycle and yield; non-standard models are set by on-site joint-debugging conditions.
Q2: Operator turnover is high; what about personnel changes?
The equipment has a low operation threshold; internal mentoring can follow this article and the manual, or contact the manufacturer for re-training or remote guidance.
Q3: How often are nozzles and jaws replaced?
There is no universal number of days; it relates to rivet material, daily output and maintenance intensity; replace as soon as inspection finds wear beyond limit, and high-cycle lines are advised to keep 1-2 sets in stock.
Q4: Can the equipment run continuously for 24 hours?
The model is designed to support long-duration continuous work, but the air source must be ensured and in-shift cleaning and wear-part inspection done; the specific continuous-run rating follows the model manual.
