Kana totaura nezvazvokufa kukandira, kune maitiro maviri anoteverwa - HPDC (High-Pressure Die Casting) kana Gravity die casting (Low-Pressure Die Casting). Ose ari maviri anoenderana nemamiriro akasiyana asi anoshandisa maitiro akafanana kuti awane yekupedzisira kuburitsa.

Gravity die casting ndeimwe yenzira dzekutanga dzekukanda kufa dzakagadzirwa nevanhu. Nokufamba kwenguva, yakagamuchira kuvandudzwa kukuru maererano nemidziyo uye kushanda kwese kwese.

Muchikamu chino, tinokurukura giravhiti kufa kukanda, zvakanakira, uye maitiro ayo.

Definition of gravity die casting

Gravity die casting imhando yekukandira kufa inobatsira kune yakakura nhepfenyuro kugadzirwa. Inowana kushandiswa mumaindasitiri akati wandei nekuda kwemitengo shoma uye yemhando yepamusoro kuburitsa iyo inowana nekukanganisa kushoma kwevanhu. Maitiro acho anoshandiswa kune asiri-ferrous alloy zvikamu, kazhinji aluminium, mhangura, uye zinc-based.

Iyo yemazuva ano giravhiti inofa yekukanda maitiro inogona kuve otomatiki kusvika pamwero mukuru. Yakanyatsokodzera mahombe, akakora zvikamu zvinoda mazinga epamusoro. Zvigadzirwa kubva mukuita uku zvinopa kupedzisa kwepamusoro uye michina zvivakwa zvichienzaniswa nekukanda jecha. Iyo ine zvakare yakakwira yekukanda mwero kana ichienzaniswa nealuminum jecha kukanda.

Zvakasiyana sei nekukanda kwepamusoro-kudzvanya kufa?

High-pressure die casting inoshandisa kudzvanywa mushure mekupinza mvura mudhishi. Inoda michina yakaoma uye inotevedzera zvachose otomatiki maitiro kuti uwane mhedzisiro. Gravity die casting haisi iyo yakazara otomatiki maitiro, inotungamira kuderera kuchinjika. Gravity die casting ndiyo zvakare yakachipa pazviviri izvi.

Zvishandiso zvesimba rinokwevera zvinhu pasi zvinofa

Gravity die casting inowana kushandiswa mumakumi ezviuru emaindasitiri, senge maturusi ekicheni, mota, zvinhu zvekuvhenekesa, uye zvimwe, zvine nyaya dzekushandisa dzinoverengeka. Izvo zvakanaka pakugadzira zvikamu, zvakadai semaknuckles, injini cylinder heads, injini blocks, pistons, etc. Nzira yekugadzira haina kusvibiswa uye inonyatsokodzera kugadzira zvinhu muhuwandu hwakawanda.

Gravity die casting process

Gravity die casting inofarirwa zvakanyanya nekuda kweiyo clutter-isina uye yakatwasuka nzira. Inoda mashoma emuchina, uye iwe unogona kudhiza iyo inobuda kusvika pamwero. Kana iwe uchitsvaga mavhoriyamu akakwira, unogona otomatiki chikamu chakakosha chemaitiro.

Hezvino zvinhu zvinosanganisirwa mune yechinyakare gravity die casting process -

1. Kugadzirira kufa

Maitiro acho anotanga nekudziisa kufa uchishandisa gasi zvinopisa uye kupfapfaidzwa nerefractory coating. Inogona kushandiswa kakawanda uye inobatsira mukubviswa kwekukanda. Inotarisirawo mazinga ekushisa. Nhengo dzefa dzinounganidzwa uye dzakasungwa.

2. Jekiseni remvura

Mushandi anodira simbi yakanyungudutswa mudhishi. Iyo simbi yemvura inosara kuti igadzike uye itore chimiro chekukanda kwemaawa mashoma. Mukukandira kwegiravhiti, mushandisi wemuchina anoshandisa kudira pasi, uye anozadza mvura yacho achishandisa sprue pasi.

3. Ejection

Kana simbi ichinge yaiswa, iyo die inovhurwa, uye ivo vanoburitsa castings. Chikamu chinotevera chinosanganisira kubviswa kwezvikamu zvakakandwa uye mapini ejection nemaoko. Zvimedu, kusanganisira magedhi, sprues, runners, uye flash, zvinobviswa kubva pakakanda.

4. Shakeout uye kupenya

Iwo ma castings anobva asungwa uye anobatwa-kupisa (chero pazvinenge zvichidikanwa). Iyo yekugadzirisa inobatsira mukubviswa kwechero mipendero yakapinza uye excel zvinhu. Iyo yekupedzisira maitiro inosanganisira kuputika kuchenesa kuti ipe polish inodiwa kune yekupedzisira zvigadzirwa.

Zvakanakira

Hezvino zvikonzero nei giravhiti kufa kukanda kuri kuwana mukurumbira wakawanda -

• Iyo ndeimwe yeanodhura-inoshanda maitiro ekukanda kufa
• Inobatsira kune zviri nyore castings, zviri nani zvidiki, zvine yunifomu yemadziro ukobvu uye pasina intricacies
• Yakanaka dimensional kurongeka nekukurumidza kugadzira nguva
• Iyo inonyanya kukodzera kumazinga epamusoro
• Iyo yekupfekedza inogona kushandiswa kakawanda uye inoda kushoma kwekudyara kana mari yekutanga yavepo
• Inogona kuburitsa zvikamu zvine top-notch mechanical properties (senge yakaderera gasi porosity uye zviyo zvakatsetseka) inonyanya kukodzera kurapwa kwekupisa.
• Chigadzirwa chekupedzisira chinoda kupera kushoma uye kusungirirwa nekuda kwekunakirwa kwayo

Putira

Pane zvinhu zvakati wandei zvinofanirwa kutariswa usati wafunga nezveprecision die castingnzira yaunosarudza. Inosanganisira zvinodiwa zvemhando yakadai sekuoma, kutendeseka, kupera kwepamusoro, uye michina yemagetsi. Isu tinofanirwawo kufunga nezvekutungamira nguva, chiyero chekugadzira, uye zvimwe zvekutengesa zvinhu. Simbi dzine mapoinzi epamusoro ekunyungudika haasi akanyanya kunaka ekukanda giravhiti.
