Parte di lavorazione in plastica<\/figcaption>\n<\/figure>\n\n\n\n

L'accoppiamento per interferenza \u00e8 un modo comune di collegamento meccanico; la tolleranza dell'accoppiamento per interferenza \u00e8 diversa per le parti in plastica lavorate e per le parti in acciaio. Se l'entit\u00e0 dell'interferenza \u00e8 troppo grande, le parti in plastica si rompono facilmente con il montaggio a pressione.<\/p>\n\n\n\n

Spieghiamo alcuni dettagli di un caso reale, accaduto presso l'officina di lavorazione di precisione SYM.<\/p>\n\n\n\n

Guardate l'immagine del disegno come sotto, completiamo sempre le parti lavorate secondo il disegno dei clienti.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Materiale: PVC
Sulla superficie laterale sono presenti due fori per l'inserimento a pressione di un perno.
Dimensione del foro: 6,25 mm
Dimensione del perno: 6,35 mm<\/p>\n\n\n\n

Non esiste una tolleranza precisa per questi due fori. Rispettiamo le tolleranze +\/- 0,1 mm e realizziamo anche il foro a 6,15-6,35 mm, se non diversamente specificato.<\/p>\n\n\n\n

La prima volta abbiamo praticato i fori vicino alla tolleranza inferiore, 6,15-6,25 mm. Il risultato del lavoro di assemblaggio \u00e8 che le parti in plastica si sono incrinate.<\/p>\n\n\n\n

\n
\"\"<\/a><\/figure>\n<\/div>\n\n\n\n

La seconda volta abbiamo fatto i fori vicino alla distanza superiore, 6,3-6,35 mm. Il lavoro di assemblaggio procede senza problemi.<\/p>\n\n\n\n

Pertanto, per ridurre il problema della lavorazione.<\/p>\n

Per prima cosa, durante la progettazione dei prodotti, dobbiamo segnare la dimensione con tolleranza stretta per il montaggio a pressa.<\/p>\n

D'altra parte, il produttore di macchinari deve essere molto professionale.<\/p>\n
