Hababka loo gooyo xadhigga trapezoidal

Dunta trapezoidal waa dun gudbin ah oo si weyn loo isticmaalo, kaas oo inta badan lagu farsameeyo qalabka mashiinka CNC. Sababtoo ah shuruudaha saxda ah ee sare ee dunta trapezoidal, ayaa habka makiinada waxay noqon doontaa mid aad u adag sababtoo ah saxnaanta iyo sababo kale. Dhibaatooyinka ugu muhiimsan waxay noqon doonaan caajis ama daloolin. Haddii qalabku dhaawacmo, mishiinka ayaa dhaawacmi doona. Laakiin ilaa inta falanqaynta tignoolajiyada mashiinada ay tahay mid macquul ah, habab farsamo oo wax ku ool ah ayaa la isticmaalaa, iyo tilmaamaha barnaamijka saxda ah ayaa la isticmaalaa, dunta trapezoidal tayo leh ayaa la samayn karaa.

Waa muhiim in la bilaabo. Haddii aad rabto inaad sameyso dunta trapezoidal wanaagsan, waxaad u baahan tahay inaad ogaato sida loo xisaabiyo dunta trapezoidal.

Xagasha iliggu: 30 ° ayaa lagu qeexay heerka Shiinaha, garoonka: lagu nidaamiyay heerka dunta.

Ballaca lafaha: f = 0.366P.

Ballaca hoose ee alveolar: w = 0.366P-0.536αc

Dunta trapezoidal dibadda: dhexroor weyn (dhexroor magaca) d; dhexroorka dhexe d2 = d-0.5P; dhexroor yar d3 = d-2h3; dhererka iliga: h3 = 0.5P + αc

Koodhka dunta trapezoidal: Koodhka dunta trapezoidal-ka waxa u taagan xarafka "Tr" iyo dhexroorka magaca ee × garoonka, unugga waa mm. Dunta gacanta bidix waxay u baahan tahay in lagu calaamadiyo "LH" ka dib cabbirka cabbirka, iyo dunta gacanta midig uma baahna in la calaamadiyo.

Si toos ah ugu imow baabuurka muhiimka ah-CNC G76 dunta qalalan ee trapezoidal.

Qaabka barnaamijka oo leh tilmaamaha G76

G76 P (m) (r) (α) Q (△ dmin) R (d)

G76 X (U) Z (W) R (i) P (k) Q (△ d) F (L)

m: wakhtiyada dunta dhammaynta 00 ~ 99 (cutub: waqtiyo).

r: qadarka dabada dunta, qiimaha waxa lagu dejin karaa inta u dhaxaysa 00 iyo 99 (cutub: 0.1 × L, L waa rasaas).

α: xagasha caarada daabka. Waxaad dooran kartaa mid ka mid ah 80 °, 60 °, 55 °, 30 °, 29 ° iyo 0 °.

△ dmin: Qadarka dib-u-quudinta ugu yar (qiimaha radius) marka duntu qallafsan tahay, unugga: μm. Marka qadarka dib-u-quudinta inta lagu jiro hawlgalka wareegga uu ka yar yahay qiimahan, qadarka dib-u-quudinta ayaa lagu quful qiimahan.

d: Gunnada mashiinka (qiimaha radius) ee dunta dhammaynaysa, unugga: mm.

X, Z: Isku-dubbaridka barta goynta dunta.

U, W: Kordhinta isku xidhka qiimaha barta dhamaadka dunta marka loo eego barta bilowga meertada.

i: Farqiga dhexroorka dunta (barta ka bilaabata goynta dunta marka loo eego barta goynta dunta), unugga: mm.

k: dhererka dunta (qiimaha radius), unugga: μm. Ku xisaabi k = 0.6495P.

△ d: inta mindida uu cunay dunta hore ee gadaale, unugga: μm.

L: hogaanka dunta, unugga: mm.

U noolow si aad wax u barato, u isticmaasho si aan joogsi lahayn, u qaado Tr36X6 tusaale ahaan si aad dhab ahaan u isticmaasho G76

Dhererka iligga h3 = 0.5P ＋ αc = 3.5

Dhexroor weyn d = 36;

Dhexroor yar d = d-2h3 = 36-2 × 3.5 = 29

Rogashada dunta trapezoidal
