Zvinhu zve thread

Tambo yacho inosanganisira zvinhu zvishanu: chimiro, dhayamita yezita, nhamba yemitsara, pitch (kana lead), uye gwara rekutenderera.CNC machining chikamu

1. rudzi rwezino
Chimiro chechidimbu cheshinda chinodaidzwa kuti chimiro chechimiro panzvimbo yechikamu ichipfuura nepakati peakisi yeshinda. Kune makona matatu, trapezoid, zigzags, denderedzwa arcs, uye rectangles.
Thread profile kuenzanisa:

 

 
2. Diameter

Pane yekutanga kana dhayamita (D, d), yepakati dhayamita (D2, D2), uye dhayamita diki (D1, D1) mushinda. Iyo dhayamita yezita inomiririra saizi yeshinda.

Iyo dhayamita yezita yeshinda yakafanana ndiyo yekutanga dhayamita.CNC inoshandura chikamu

 

 
Shinda rekunze (kuruboshwe) mukati (kurudyi)

 
3. nhamba yemutsara
Tanda inoumbwa nehelix imwe inodaidzwa kuti shinda-mutsetse mumwe chete, uye shinda inoumbwa nemaherokisi maviri kana anopfuura akagovaniswa zvakaenzana achitevedza gwara reaxial inonzi shinda-mitsetse yakawanda.
Single

shinda (kuruboshwe) shinda mbiri (kurudyi)anodizing aluminium chikamu

4. Pitch uye mutungamiri
Pitch (P) chinhambwe cheaxial pakati pemapoinzi maviri anowirirana pamutsetse wedhayamita yemeno maviri ari padyo.
Lead (PH) chinhambwe cheaxial pakati pemazino maviri akabatana pahelix imwechete uye mapoinzi maviri anoenderana pamutsetse wedhayamita.
Kune shinda imwe chete, lead = pitch; kune-multi-thread, lead = pitch × nhamba yeshinda.

 

5. kutenderera nzira
Shinda inopindirwa kana ichitenderedzwa newachi inonzi shinda yekurudyi;
Shinda inopindirwa kana ichitenderedzwa newachi inonzi shinda yekuruboshwe.

 

Shinda yekuruboshwe, shinda yekurudyi.
