Ichikandamo jecha-nevhu anoumba: zvakanakira

The dzinotsanagura foundry kugadzirwa nesimbi blanks dzinorongwa nenzira dzakasiyana. Sezvo zvichiguma chigadzirwa zvikuru zvinoenderana pahwaro zvainyanya nemhaka munhu simulated chinhu, ndiro chimiro, hondo anozadza remangwana workpiece zvinhu. Chimwe chezvinhu dzakakurumbira ruzivo ndiko vachikanda jecha-ivhu anoumba, zvinopa yakawanda zvakanakira. Nzira rakanyatsojeka akwegura, asi zviri kushingaira kushandiswa mune zvaAtemisi yakasiyana siyana - kubva okudhindira maduku makuru akaitwa.

General ruzivo pamusoro mabikirwo

Kuumbwa kwacho chinhu zvekushandisa chichiitwa, izvo zvakaita kubva yakaumbwa simbi kare kuumbwa billet kana rapera chigadzirwa pamwe zvakafanira geometrical parameters. Kuti vabudirire zvandinenge chaienzanirana zvinodiwa muenzaniso kushandiswa. Carrier ndiyo hwaro kutsinga hazvisi jecha-ivhu anoumba. It achiumbwa nemapoka maviri zvinoriumba. In chikamu zirconia uye silica jecha, uye wechipiri - kaolin uye bentonite nevhu. Nokudaro wezvamatongerwe mubatanidzwa rimwe chete kuratidzwa, izvo panguva oparesheni anogamuchira workpiece zvinhu ramangwana. Asi ichi hachisi vose zvakamisa hurongwa iro kutsinga chaitwa muchimiro jecha uye ivhu. The zvemichina haisi pasina muenzaniso Kit, inova mhando muenzaniso yemberi ikohwewe. Nokuti ichi simulation kushandiswa mollusks kana pliable ari machine nezvinhu - zvakadai huni kana chiedza simbi. Zvisinei, spineless hwaro rinoshanda chete muzviitiko apo zvakakodzera kutevedzera nangananga chinhu. Asi zvinoitika kuti tenzi kukurira vakagadzirira akagadzirwa zvigadzirwa, izvo parameters vanofanira kudzokororwa vachikanda. Zvino zvakafanira kuti vaende zvakananga kubatsira ruzivo urwu.

A zvakasiyana-siyana

Kuoma kunzwisisa kushandisa kwazvo siyana uye yokutevedzera rekukuputsirai ndechokuti zvemichina asingagoveri kuparadzwa mamiriro avo. Izvi zvinooneka ichikutadzisa magadzirirwo hwokushanda, mashandiro uye complicating vashandi. Kana jecha-ivhu siyana zvakadai zvatisingakwanisi havapo, nokuti nzira pakutanga achipfeka kushandiswa chete chakuvhuvhu. Zvisinei, izvi hazvirevi kuti reusable midziyo ari musimboti dziripowo. Nezvikonzero youpfumi fomu rinogona kushandiswa kutengeswa, kana asina dzisingapindirani zvinodiwa okupedzisira mugumisiro kwacho. Technical uye nesangano zvakanakira ichikandamo mujecha-ivhu anoumba vari zvikuru pakutsvaga tinosvika kuna hunoshanda chikamu unongotaura. Kana mumwe-chidimbu tooling vanogona kuvimba dzokubudisa ari Foroma pasina usachikanganisa, uye kuti vawane castings pamwe runodiwa parameters. pfungwa iyi rinowanzoshandiswa nyore castings. Asi kana totaura magadzirirwe workpieces yakaoma, kushandisa paradzanisa makariita chimiro, nokuti izvo chete pasina kumanikana tichitarisa runodiwa chigadzirwa parameters.

Muzvigadzirwa kuwanikwa sangano kwacho

Muenzaniso kushandisa jecha anoumba rekukuputsirai anoratidza sei zvinobetsera zvingava chinyakare kugadzirwa unyanzvi pamusoro ano. Muchiitiko ichi zvinonzi kukonzerwa nyore kukanda musangano. Nokuti mashandiro anofanira chete kuisa ichangobva kutaurwa zvokuvakisa chimiro Modelling uye tooling, izvo haatarisiri akaoma dzokuvhiya. Elementary muenzaniso pehata anogona kuitwa nedanda raizondipa unyanzvi hunodiwa womuvezi chokushandisa. Kutoti anokonzera maindasitiri kweShanduro castings kunzwisisa chimiro vari kushandiswa uye mamwe kubudiswa uye impregnating ichi zvinhu. Uyewo, kunzwisisa siyana Kudzingwa jecha nevhu chimiro yakagadzirwa nesimbi uye epurasitiki. Asi, zvakare, totaura unyanzvi kugadzirwa. Practice inoratidza kuti munyika inenge 80-90% kubva castings zvose kugadzirwa kushandisa zvivako nyore muchimiro chinyorwa maturusi uye kwakajairika nokuomesa makamuri.

upfumi feasibility

Kazhinji, kushandisa kunosanganisira chimwe kuratidzwa uye kudhura muitiro. Naizvozvo, kugadzirisa zvisarudzo zvakadaro chete Muzviitiko, kana uchida kugadzira zvikamu kana kugadzirwa tsika marudzi. Asi neizvi muitiro anoratidza foundry. Ichikandamo jecha-ivhu anoumba wakarurama mari, kunyange zviitiko apo aishandisa anoparadza nheyo. Izvi zvinogona kunzi kunodyira-zvinobudirira uye muchimiro pachayo, uye pamusoro Modelling mamiriro.

The pakawanda of zvigadzirwa

Kune vashoma zvinoumba firimu, izvo zvinogona kukutadzisa kukura kwebasa kushanda zvigadzirwa izvi. It rinoshandiswa indasitiri, kuvaka, duku-batch mangé gadzira uye chidimbu zvakakodzera zvikamu, zvikurukuru mumawekishopu, uye zvichingodaro. D. Kana chaiwo mukuru-zvakarurama Kugadzirwa mitsetse hatibvumiri izvi nokuti havagoni kupa zvakakodzera nenhanho rakarurama workpiece unhu. Asi nokubva nemaonero ari kushandiswa esimbi inonyunguduka rakakurumbira pakawanda inomira kubva mamwe ruzivo ichikandamo mujecha fomu. Muchidimbu vanoratidza kukodzera kushandisa boka refractory nesimbi inogona yakapambadzirwa marudzi. Traditional simbi iri kuumbwa zvakakwana akakodzera kushandiswa mune Kuumbwa oparesheni.

Possible Kudzingwa kuremara

The simba pfungwa ruzivo urwu, sezvo inokurukurwa kumusoro, ndiye yakaderera rakarurama parameters ari workpiece. Products vari vakawana mafungu, kwete nguva dzose zvakafanana, ichibata, uye kuvapo zvimwe zvikanganiso. nuance Ndiyo neizvi divi roughness uye nyore kugadzirwa tooling. Kunze, vachikanda mujecha muchimiro achibvumira njodzi kupinda kuraswa Zvinoumba nonmetallic inclusions. Zvichienderana simbi pachayo anogona kutora nzvimbo uye gasi porosity. Asi izvi hazvirevi kuti urema kuva chakakomba chipingamupinyi kushandiswa kwakapararira jecha Kuumbwa michina. Kuti aripire chinetso ichi kunogona zvaidiwa mitemo yepamusoro Kudzingwa.

Zvinotarisirwa kuti preform unhu

Technology Tips kutevera mitemo miviri inokosha vachauya pedyo kuwana kutarisirwa mugumisiro. Chokutanga, unofanira kudzivisa kushandiswa nzira ari pasi fluidity pamusoro simbi. Chokwadi chokuti mukuru kutonhora mwero inogona kusimudzira ndichibvunza kutonhora ari uchanyangadika, kukonzera paumbwe junctions uye underfilling. nuance Second siya risina mutengo nyanzvi kuroorwa Kudzingwa jecha-ivhu siyana zvaimunetsa zvakabviswa duku achishivirira pamusoro Vhoriyamu preform. The kuwedzera kwokutanga zviruva mberi kubvumira mechanically kunatsiridza chigadzirwa pasina mukana hazvishanduki kukuvara.

mhedziso

The zvemichina iri nyore oornag, asi hazvirevi kuti hapana zvinosanganisirei kukura. Mune dzimwe nzvimbo ichikandamo mujecha-ivhu anoumba vari upgraded, kuti optimize muitiro uye kubvisa zvimwe zvikanganiso ayo. Kupfuura vakakurumbira uye zvinovimbisa bazi nzira anoonekwa akatozotamiswa chimiro. Zvisinei Principles kushandisa jecha kuramba chete, sezvo ivhu bhainda chinoumba boka hwaro iyi Kwabviswa.
