7 Thread Processing Nzira

1. Kucheka shinda

Kazhinji, inoreva nzira yekugadzira shinda paworkpiece nekugadzira chishandiso kana kugaya mudziyo, kunyanya kusanganisira kutenderedza, kugaya, kugogodza uye shinda kugaya, kugaya uye kucheka chamupupuri, nezvimwewo. mudziyo wemuchina unova nechokwadi chekuti chishandiso chekutenderedza, chigayo chekucheka kana vhiri rekukuya chinofambisa mutobvu nemazvo uye zvakaenzana pamwe neaxial kutungamira kweworkpiece kutenderera kwese kwechishandiso. Kana uchibaya kana shinda, chishandiso (pombi kana kufa) chinotenderera chinoenderana nechokushandisa, uye yekutanga yakaumbwa shinda groove inotungamira chishandiso (kana workpiece) kufamba axially.

 

2. Kutenderedzwa kweshinda

Kugadzira tambo yekutenderedza kana tambo kadhi chishandiso chinogona kushandiswa kutenderedza shinda pa lathe (ona shinda yekugadzirisa chishandiso). Kutenderedza shinda nekugadzira kushandura chishandiso inzira yakajairika yechidimbu chimwe chete uye diki batch kugadzirwa kweshinda yekushanda nekuda kwechimiro chayo chiri nyore; kushandura shinda ine shinda yekumisikidza chishandiso ine yakakwirira kugadzirwa kwehunyanzvi, asi chimiro chayo chakaomarara, saka chakakodzera chete kushandura shinda pfupi workpiece ine mazino akanaka mukati uye yakakura batch kugadzirwa. Kurongeka kwepitch yekushandura trapezoidal thread ine general lathe inogona kungosvika 8-9 mazinga (jb2886-81, zvakafanana pazasi); kugadzirwa kana kurongeka kunogona kuvandudzwa zvakanyanya kana uchigadzira shinda pane yakasarudzika tambo lathe.cnc machining chikamu

 

3. Kugaya shinda

Pamushini wekugaya, disc milling cutter kana comb milling cutter inoshandiswa pakugaya. Disc milling cutter inonyanya kushandiswa kugadzira trapezoid yekunze shinda ye screw rod, worm uye mamwe maworkpieces. Comb milling cutter inoshandiswa pakugaya mukati nekunze tambo yakajairika uye taper shinda. Nekuti kureba kwechikamu chayo chekushanda chakareba kupfuura kureba kweshinda kuti igadziriswe neakawanda edge milling cutter, iyo workpiece inogona kugadziriswa chete nekutenderera 1.25-1.5 revolutions, ine kugadzirwa kwakanyanya. Kurongeka kweshinda kweshinda kunogona kusvika 8-9 mamakisi, uye kushata kwepamusoro kuri r5-0.63 μ M. Iyi nzira yakakodzera kugadzirwa kwehuwandu hwe general precision shinda workpiece kana rough machining isati yakuya.cnc milling chikamu

 

4. Kukuya shinda

Iyo inonyanya kushandiswa kugadzira tambo chaiyo yeyakaomeswa workpiece pane shinda grinder. Zvinoenderana neyakasiyana-muchinjika-chikamu chimiro chevhiri rekukuya, rinogona kupatsanurwa mumhando mbiri: mutsara mutsetse wekukuya vhiri uye mitsetse yakawanda yekukuya vhiri. Iko kurongeka kweiyo mutsara wekukuya vhiri giredhi 5-6, uye kushata kwepamusoro kuri r1.25-0.08 μ m, saka zviri nyore kupedzisa vhiri rekukuya. Iyi nzira yakakodzera kukuya precision screw, thread geuge, worm, batch diki reshinda workpiece uye hobho chaiyo. Kune marudzi maviri enzira dzekukuya: longitudinal kugaya uye kucheka mukukuya. Upamhi hwegumbo rekukuya nelongitudinal kugaya nzira ishoma pane kureba kweshinda inofanira kukuyiwa, uye shinda inogona kukuya kusvika pakukura kwekupedzisira mushure mekunge vhiri rekukuya richifamba kureba kamwe kana kakawanda. Hupamhi hwegumbo rekukuya yeguyo pakugaya nzira yakakura kudarika urefu hweshinda inofanira kukuyiwa. Gumbo rekukuya rinocheka mukati meiyo workpiece radially, uye workpiece inogona kukuyiwa mushure mekutendeuka anenge 1.25 revolutions. Kugadzirwa kwacho kwakakwira, asi kurongeka kwakadzikira zvishoma, uye kupfeka kwegumbo rekukuya kunowedzera kuoma. Iyo nzira yekucheka inokodzera kufoshora mapombi akawanda uye kukuya dzimwe shinda dzekusunga.chikamu chepurasitiki

 

5. Kukuya shinda

Rudzi rwenati kana screw type thread lapping tool inogadzirwa nezvinhu zvakapfava senge simbi yakakandwa. Zvikamu zveshinda yakagadziridzwa pane workpiece ine pitch error inogayiwa nekuenda mberi nereverse kutenderera kuti ivandudze kunaka kwenzwi. Iyo yakaomeswa shinda yemukati inowanzobviswa nekukuya kuvandudza kurongeka.

 

6. Kubata uye kupinza

Kubaya ndiko kushandisa imwe torque kukwenya pombi mugomba repasi rakacherwa kare pane workpiece kugadzirisa shinda yemukati.

Kurukwa ndiko kucheka shinda yekunze pabhara (kana chubhu) workpiece ine difa. Iko machining iko kurongeka kana kupinza kunoenderana nekurongeka kwepombi kana kufa. Kunyangwe paine nzira dzakawanda dzekugadzirisa tambo dzemukati nekunze, diki-dhayamita dzemukati tambo dzinogona kungogadziriswa nemapombi. Kutepa nekupinza kunogona kuitwa nemaoko kana nelathe, muchina wekuchera, muchina wekutepa uye muchina wekupinza.

 

7. Thread rolling

Iyo nzira yekugadzirisa yekugadzira uye kukungurutsa kufa kuti ibudise epurasitiki deformation yeworkpiece kuti uwane shinda yekutenderedza inowanzoitwa pamushini wekukunguruka weshinda kana iyo otomatiki lathe yakasungirirwa nekuvhura otomatiki uye kuvhara tambo inotenderedza musoro, iyo inokodzera kugadzirwa kwakawanda kweshinda yekunze. patani yezvitsiga zvakajairwa uye mamwe majoini ane shinda. Kazhinji, dhayamita yekunze yetambo inoputika haisi kupfuura 25 mm, kureba hakusi kupfuura 100 mm, uye tambo yakarurama inogona kusvika pazinga 2 (gb197-63). Uyo dhayamita rechinhu chisina chinhu chakashandiswa chinoda kuenzana nedhayamita yehupamhi hweshinda ichagadziriswa. Kazhinji, shinda yemukati haigone kugadziriswa nekukunguruka, asi kune iyo yakapfava workpiece, iyo inotonhora extrusion yemukati shinda inogona kushandiswa pasina slot extrusion tap (iyo yakakura dhayamita inogona kusvika anenge 30mm), uye iyo inoshanda musimboti yakafanana nekutapa. Iyo torque inodiwa pakutonhora kuwedzeredza kweshinda yemukati yakakura zvakapetwa ka1 pane iyo yekutepa, uye iyo machining chaiyo uye yemhando yepamusoro yakakwira zvishoma pane iyo yekubaya.

Zvakanakira kupeta shinda ndeizvi: ① kushata kwepamusoro kushoma pane kutenderera, kugaya nekukuya; ② pamusoro peshinda mushure mekukunguruka kunogona kuvandudza simba uye kuoma nekuda kwekutonhora kwebasa kuoma; ③ mwero wekushandiswa kwezvinhu wakakwira; ④ kugadzirwa kwakapetwa kaviri zvichienzaniswa nekucheka maitiro, uye zviri nyore kuziva otomatiki; ⑤ hupenyu hwesevhisi hwekukunguruka kufa hwakareba kwazvo. Zvisinei, kuoma kwezvinhu zvekushanda hakusi kudarika hrc40, kururamisa kwehukuru husina chinhu hunodiwa kuti huve hwakakwirira, kurongeka uye kuoma kwekufa kunodawo kuve kwakakwirira, saka zvakaoma kugadzira iyo inofa. uye haina kukodzera shinda ine asymmetric rolling Profile.

 

Zvinoenderana neyakasiyana-siyana yekukunguruka, shinda inogona kupatsanurwa mumhando mbiri: shinda yekumonereka uye shinda.

 

Thread rolling: mahwendefa maviri eshinda ane shinda profiles anodzika uye akarongwa ne1/2 pitch. Iyo static plate inogadziriswa uye ndiro inofamba inofamba mumutsara unodzokorora wakatwasuka wakafanana neplate yakamira. Kana iyo workpiece inotumirwa pakati pemahwendefa maviri, ndiro inofamba inofamba inoenda mberi kukwesha uye kudzvanya iyo workpiece, ichiita iyo pamusoro pepurasitiki deformation uye kugadzira shinda.

Kune marudzi matatu ekukunguruka: radial rolling, tangential rolling uye kuumburuka musoro.

 

① radial tambo inokunguruka: maviri (kana matatu) shinda yakaumbwa shinda inomonereka mavhiri akaiswa paakaenzana mashaft anoenderana, workpiece inoiswa parutsigiro pakati pemavhiri maviri, uye mavhiri maviri anotenderera nekumhanya kwakafanana munzira imwe chete. iyo inoitawo radial feed motion. Iyo workpiece inofambiswa nevhiri rinotenderedza kuti ritenderere, uye nzvimbo yacho inoburitswa radially kuita shinda. Yakafanana nzira yekutenderedza inogona zvakare kushandiswa kune mamwe screws ane yakaderera chaiyo zvinodiwa.

 

(2) tangential shinda inokunguruka: inozivikanwawo sekutenderera kweshinda. Chishandiso chekumoneredza chine vhiri repakati rinotendereka uye matatu akagadzika-arc-shapa mahwendefa. Munguva yekukunguruka, iyo workpiece inogona kudyiswa nguva dzose, saka chibereko chakakwira kupfuura icho chekukwesha shinda uye radial rolling.

 

③ kutenderedzwa kweshinda yeshinda inotenderedza musoro: inoitwa pane otomatiki lathe uye inowanzo shandiswa kugadzira shinda pfupi pane workpiece. Kune 3-4 rolling rollers yakagoverwa zvakafanana kutenderedza workpiece. Kana uchikunguruka, workpiece inotenderera, uye musoro unotenderera unodyisa axially kuti ubvise workpiece kunze kweshinda.
