Fenómeno do problema
Healds break early during high-speed reciprocation of the loom
Análise das causas
Healds reciprocate and bend hundreds of times per minute, and fatigue life depends on material toughness and surface smoothness; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Solução
Select high toughness special grades; mirror polish the heald surface; select grades according to loom manufacturer reciprocating fatigue standards; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Conclusão principal
Healds are selected with reciprocating fatigue special grades; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
