Nzira yekuvandudza sei kurongeka kwepurasitiki molds?

1. Mold processing quality inosanganisira kugadzirisa kunyatsoita uye pamusoro pehutano

Machining kunyatsoita chiyero chekuenderana pakati pehukuru chaihwo, chimiro uye chinzvimbo chepamusoro pechikamu chakagadzirwa uye yakakodzera geometric paramita inodiwa nedhirowa.
Iyo yakakodzera geometric parameter, yehukuru, ivhareji saizi; Kune iyo yepamusoro geometry, ndiyo mhedziso denderedzwa, silinda, ndege, koni uye mutsara wakatwasuka. Nokuti mutual chinzvimbo pakati pezviso, zviri zvachose parallel, vertical, coaxial, symmetric, etc. The kutsauka pakati chaiwo geometrical parameters uye chakanakira geometrical parameters chikamu anonzi machining kukanganisa.
Machining kunyatsoita uye kukanganisa kwekugadzira ese ari maviri mazwi anoshandiswa kuongorora iyo geometric paramita yenzvimbo dzakagadzirwa. Machining accuracy inoyerwa negiredhi rekushivirira, iyo diki kukosha kwegiredhi, iyo yakakwirira yekururama; Iko kukanganisa kwekugadzira kunoratidzwa nehuwandu hwenhamba, uye iyo yakakura kukosha kwenhamba, iyo yakakura kukanganisa. High processing accuracy inoreva kukanganisa kuduku kwekugadzirisa, uye zvinopesana.
Izvo zviyero zvakawanikwa nenzira ipi zvayo yekugadzirisa hazvizove zvakanyatsorurama, kubva pakushanda kwechikamu, chero bedzi kukanganisa kwekugadzirisa kuri mukati mekushivirira kunodiwa nechikamu chekudhirowa, kururamisa kwekugadzirisa kunofungidzirwa kuve kwakavimbiswa.
Hunhu hwemuchina hunoenderana nemhando yekugadzira yezvikamu uye kunaka kwekusangana kwemuchina. Iyo michina yemhando yezvikamu inosanganisira kurongeka kwekugadzira kwezvikamu uye nepamusoro pemhando yezvikamu zviviri. Kurongeka kwekugadzira kunoreva dhigirii iyo chaiyo geometric parameters (saizi, chimiro uye chinzvimbo) chezvikamu mushure mekugadzirisa zvinopindirana neakakodzera geometric paramita.
Musiyano pakati pavo unonzi machining error. Saizi yekukanganisa machining inoratidza iko iko kwekugadzira. Iyo yakakura kukanganisa, kuderera kweiyo machining kurongeka, uye kudiki kukanganisa, kunowedzera kurongeka kwekugadzira.

2. Mamiriro makuru anokanganisa kugadzirisa kurongeka

2.1 Dimensional kurongeka
Inoreva chiyero chekuenderana pakati pehukuru chaihwo hwechikamu chakagadzirwa uye yekushivirira nzvimbo yepakati yehukuru hwechikamu. Dimensional kurongeka kunodzorwa nedimensional tolerances. Dimensional tolerance ndiyo inotenderwa musiyano muhukuru hwechikamu panguva yekucheka. Panyaya yehukuru hwakafanana, iyo idiki iyo dimensional kushivirira uye inokwidza iyo dimensional yechokwadi.

2.2 Kurongeka kwechimiro
Inoreva dhigirii rekuenderana pakati peiyo chaiyo geometry yeiyo mashini chikamu chepamusoro uye yakanakira geometry. Pane zvinhu zvitanhatu zvekuongorora kurongeka kwechimiro, sekutwasanuka, flatness, kutenderera, cylindricity uye mutsara profiles. Kurongeka kwechimiro kunodzorwa nekushivirira kwechimiro, uye chimiro chega chega kushivirira chakakamurwa kuita gumi nembiri mazinga kunze kwegumi nenhatu nhanho dzekutenderera uye cylindricity. Level 1 ndiyo yepamusoro-soro uye nhanho yegumi nembiri ndiyo yakaderera.

2.3 Kurongeka kwenzvimbo
Zvinoreva mutsauko mukurongeka chaiko pakati penzvimbo dzakakodzera dzezvikamu zvemuchina. Pane zvinhu zvisere zvekuongorora kurongeka kwenzvimbo, senge parallelism, perpendicularity, inclination, coaxiality, symmetry, chinzvimbo, kutenderera kumhanya uye kumhanya kwakazara. Kurongeka kwenzvimbo kunodzorwa nekushivirira kwechinzvimbo, izvo zvakare zvakakamurwa kuita 12 nhanho dzechokwadi.
