Automated Systems Solve Burr And Clamping Issues In SC Terminal Lugs Manufacturing
PLC automated systems eliminate traditional SC Terminal Lugs processing defects through integrated magnetic stroke switches and pneumatic deburring units. Precise sequence timing stabilizes clamping force, removes edge burrs automatically, and raises final assembly yields above 98%.
Key Takeaway: Replacing manual shearing with sensor-timed pneumatic control resolves stock slippage, eliminates manual grinding steps, and prevents insulation damage during downstream assembly.
Quality Bottlenecks in Traditional Terminal Processing
Unstable holding force causes workpieces to shift during shearing. This misaligns the crimping barrel on tinned copper wire lugs, leading to asymmetrical wall thickness and loose electrical connections.
Uncontrolled cutting pressure leaves severe burrs on trimmed edges. These rough metal edges cut protective insulation sleeves and require labor-intensive manual grinding operations that slow production.
Residual copper fragments frequently stick to stamping dies. Uncleared debris prevents proper seating for tinned copper terminal ends, causing dimensional variance across high-volume production batches.

-
Magnetic Stroke Sensing: Magnetic reed switches monitor cylinder positions in real time. They trigger instant pneumatic clamping once stock enters the die, preventing slippage before punch actuation occurs.
-
Automated Inline Grinding: Integrated deburring modules deploy immediately following the shearing stroke. Rotating abrasive heads remove perimeter flash, delivering clean edges across all processed tinned copper terminals.
-
Pneumatic Scrap Ejection: High-pressure air nozzles blast residual trim away after every cycle. Clean die cavities maintain exact positioning accuracy for tinned cable lugs throughout continuous operations.
Performance Metrics Comparison

Quick Action Plan for Line Upgrades
To maximize pass rates instantly, install magnetic position sensors directly onto existing pneumatic cylinders to lock feeding tolerances before upgrading edge-grinding attachments.
