Apo mainjiniya anotsanangura low pressure jecha kukanda nokuda kwezvikamu zvesimbi zvakarurama, havasi kungosarudza nzira-vari kusarudza anchor yakavimbika. Isu takazvionera pachedu: pombi ye hydraulic pombi yakatsemuka mukuyedzwa kwemunda nekuti iyo yekutanga yakasvetuka yekusimbisa modhi. Mumwe mutengi akanonoka kuvhurwa nemavhiki gumi nerimwe mushure mekugamuchira humburumbira dzimba dzine isingaenderane graphite nodule kugovera - isingaonekwe pasina metallography, asi inouraya pasi pe350-bar cyclic kurodha. Ndicho chikonzero "low pressure sand casting factory" haisi generic search term. Iyo sefa-iyo inoparadzanisa vatengesi vanonzwisisa kudzora kwesimbi kubva kune avo vanongodira simbi.
Nei Kudzikira Kudzvanya Jecha Kukandira Kuchipa Hurukuro Iko Kunotadza kusimba
Gravity casting inoshanda kune zvimiro zviri nyore. Asi kana chikamu chako chine zvikamu zvakatetepa-zvakakomberedzwa nekunyura kukuru-kunge piston pombi silinda imba ine 4.2 mm mudhuri ukobvu inonyura mu68 mm flange-simba rinokwevera pasi rinokonzeresa mhirizhonga, kuvharika kwechando, uye kuderera kweporosity panguva dzakaoma dzekushushikana. Kukanda kwejecha kwakaderera kunogadzirisa izvi nekuisa 0.05–0.15 bhaa yakadzorwa inert gasi kudzvanywa kune yakanyungudutswa simbi reservoir. Izvi zvinomanikidza simbi kukwira kuburikidza neceramic riser chubhu painodzorwa velocity (kazhinji 12–18 mm/s), ichizadza mhango yemold laminar. Zvakaguma nei? Yekusimba kusimba kubva pasi kuenda kumusoro, pedyo-zero yakavharirwa gasi, uye dimensional kugadzikana mukati me ± 0.25 mm pazvinhu zvinosvika 1,200 mm kureba.
Isu tinosimbisa izvi zuva nezuva. PaAMS 5387 cobalt alloy nozzles, low pressure casting inowana 99.7% kunzwika mukuyedzwa kwe ultrasonic — maringe ne89% negiravhiti. Zvinotonyanya kukosha, inopa inowirirana eutectic carbide dispersion. Izvo zvine basa nekuti isina kuenzana carbide network inokonzeresa kupfeka nguva isati yakwana munzira dzakakwirira-velocity fluid. Vatengi vedu muoiri & gasi shumo 3.2 × hurefu hwehupenyu hwesevhisi paT800-based plugs inokandwa nenzira iyi inopesana nekudyara-kukanda dzimwe nzira-hapana coating inodiwa.
Zvina Zvisingataurwi Zvinogona muIchokwadi Yakaderera Kudzvinyirira Sand Kukanda Factory
Iyo yakasimbiswa ISO 9001 nzvimbo ndeye masiteki etafura. Chii chinoparadzanisa vanoita-vakagadzirira vadyidzani ndeyekuti vanosanganisa sei kukanda nezvido zvepasi:
- Material traceability kusvika pakupisa nhamba: Batch yega yega yecobalt-nickel alloy inotakura maMTR akazara ane tensile, kuomarara, uye intergranular corrosion test data-kwete chete chemistry.
- In-process solidification monitoring: Thermal imaging kamera inoteedzera kufambira mberi munguva chaiyo; kutsauka kunokonzeresa otomatiki kudzvanywa kana kubvisa nhumbu.
- CMM-yakabatanidzwa pateni verification: Tisati tatanga kudira, isu tinoongorora master mapatani kurwisa CAD tichishandisa Zeiss CONTURA G2, tichibata dhizaini zvikanganiso zvingakonzeresa kukuvara kwe ejection.
- Hybrid kupedza kugona: Castings anobuda pachiteshi chekuzunza uye akananga ku5-axis CNC machining-hapana kubata kwekunze. Izvi zvinochengetedza datum kuperera kweGD&T-akakosha maficha senge coaxiality pakati pekubereka uye kukwira kumeso (± 0.015 mm).
Vamwe vanogona kupokana kukanda jecha hakugone kuenderana nekudyara kwekudyara kwepasi pekupedzisira. Chokwadi - kune girazi rinopera. Asi kune inoshanda nzvimbo? Yedu se-yakakandwa Ra inogara pa12.5 µm pazviso zvekutanga zvinotakura mutoro, ichidonha kusvika 1.6 µm post-machining. Izvo zvakakwana: yakanyanyisa kutsvedzerera inokoka lubricant nzara mune yakakwirira-slip application senge winch centre shaft rollers.
Iko Precision Inosangana Nechokwadi Chekushandisa
Kukanda kwakaderera kwejecha kunopenya uko fizikisi uye basa zvinobonderana. Funga nezveinjiniya mota paboard winch masisitimu: yepakati shaft rollers inotsungirira yakasanganiswa torsional shear, radial maitiro, uye abrasive kusvibiswa. A giravity-cast roller yakakundikana pa 14,000 cycles. Yedu yakaderera kudzvanywa shanduro-ichishandisa yakagadziridzwa girini jecha ine bentonite uye kabhoni additives-yakapona 62,000 macycles mukukasira kuyedzwa. Sei? Inodzorwa kutonhora mwero yakachengetedza 22% mamwe ekutanga carbides mu subsurface layer, yakasimbiswa neSEM/EDS mepu.
Kana kutora mavharuvhu ekumanikidza e hydraulic system. Vatengi vanoda kuvhiya-kusina kushanda pa420 bar. Maitiro edu anobata gedhi chigaro flatness kusvika 0.008 mm kuyambuka 85 mm dhayamita-inogoneka chete nekuti kuderera kunobvisa kukukurwa kwe mold kubva kune kusagadzikana kuzadza. Isu tinoyera chigaro chevharuvhu yega yega neTaylor Hobson PGI Optics, kwete kungoita majenya.
Kusarudzwa kwezvinhu kunobatanidza zvakanakira. Paunenge uchikanda T800 cobalt-based alloys, akajairwa jecha molds anotsemuka pasi pekupisa kwekupisa. Isu tinoshandisa zircon-bonded refractory linings preheated kusvika 220 ° C-yakagadziriswa kuburikidza ne thermocouple arrays akaiswa mumadziro eforoma. Izvo zvinodzivirira microfissures inova nzvimbo dzekutangisa dzekuneta kutsemuka.
Kusarudza Yako Yakaderera Yekudzvanya Sanding Factory: Tarisa Kupfuura Bhurocha
Bvunza iyi mibvunzo mitatu usati wasaina PO:
- Unogona here kutiratidza mishumo yekusimbisa yekuenzanisa yedu chaiyo geometry-kusanganisira yakafanotaurwa shrink cavity nzvimbo uye kudyisa kunyatsoshanda?
- Ndeipi yako yakanyanya kutendeseka kutsauka pakati pe-se-cast uye yekupedzisira michini miyero yezvimiro zvinoda zvose kukanda kuvimbika uye yakasimba GD&T?
- Iwe unoonesa sei kufanana kwemicrostructure pane imwe chete yekukandwa-kunyanya pakuchinjana pakati pezvikamu zvakakora uye zvitete?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. anopindura ese ari matatu nemaprotocol akanyorwa-kwete zvipikirwa. Yavo Qingdao nzvimbo inomhanyisa yakaderera kumanikidza jecha kukanda padivi peCNC machining uye kupisa kurapwa pasi pedenga rimwe. Hapana handoffs. Hapana dimensional drift. Hapana kurasika traceability. Vanoshandira maNorth America OEMs anoda mavharuvhu anoenderana neASME B16.34, vagadziri vepombi vekuEurope vanoda EN 10213-G25 simbi yekukandwa, uye vagadziri vemidziyo yemugodhi vekuSoutheast Asia vanoda kukanda simbi isingachinjiki — zvese zvine chirango chakafanana chesimbi.
Kana chikamu chako chinotevera chesimbi chinofanirwa kurarama nekumanikidzwa kukuru, kupfeka kwakanyanya, kana kutadza kwemhedzisiro, tanga ne yakaderera kumanikidza jecha kukanda fekitori iyo inobata kukanda kwete senhanho-asi sehwaro hwekushanda kwekuvimbika.
