Gear Wheel for Gear Hobbing Machine Yakagadzirwa neSpecial Cast Steel

(1) Low-pressure casting (low-pressure casting) Low-pressure casting: inoreva nzira iyo simbi yemvura inozadzwa ne mold pasi pemhepo yakaderera (0.02 ~ 0.06 MPa) uye yakasvibiswa pasi pekumanikidzwa kuti iite kukanda. Kuyerera kwemaitiro: Zvimiro zvehunyanzvi: 1. Kumanikidza uye kumhanya panguva yekudurura kunogona kugadziridzwa, saka inogona kuiswa kune dzakasiyana siyana dzekukanda molds (senge simbi molds, jecha molds, nezvimwewo), kukanda alloys akasiyana uye castings akasiyana siyana. sizes; 2. Uchishandisa pasi Injection type yekuzadza, iyo yakanyungudutswa simbi yekuzadza yakagadzikana, isina kupfapfaidza, iyo inogona kudzivirira kusungwa kwegasi uye kukukurwa kwemadziro nepakati, izvo zvinovandudza chiyero chekukodzera kwekukanda; 3. Kukanda kunopenya pasi pekumanikidzwa, chimiro chekukanda chakaoma, uye chinyorwa Chiri pachena, chakatsetseka pamusoro, uye yakakwirira mechanical properties, kunyanya inobatsira kukanda kwezvikamu zvakakura uye zvitete-masvingo; 4. Bvisa kudiwa kwekudyisa risers, uye kuwedzera chiyero chesimbi chekushandisa kusvika 90-98%; 5. Kuderera kwekushanda nesimba, mamiriro ekushanda akanaka, uye midziyo Zviri nyore, zviri nyore kuona mechanization uye otomatiki. Kushandisa: Kunyanya zvigadzirwa zvechinyakare (cylinder head, wheel hub, silinda furemu, nezvimwewo).

(2) Centrifugal casting: Centrifugal casting inzira yekukanda umo simbi yakanyungudutswa inodururwa muforoma inotenderera, uye mold inozadzwa pasi pechiito che centrifugal simba kuti chiome uye chimiro. Kuyerera kwemaitiro: Maitiro ekuita uye zvakanakira: 1. Iko kunenge kusina kushandiswa kwesimbi mukudurura hurongwa uye riser system, iyo inovandudza chibereko chekugadzirisa; 2. Nheyo inogona kusiiwa paunenge uchigadzira hollow castings, saka inogona kuvandudzwa zvakanyanya kana ichigadzira refu tubular castings. Kuvandudza simbi yekuzadza kugona; 3. Castings ane high density, zvishoma zvikanganiso zvakadai pores uye slag inclusions, uye yakakwirira mechanical properties; 4. Zviri nyore kugadzira barrel uye sleeve composite metal castings. Zvakaipa: 1. Pane zvimwe zvinogumira kana zvichishandiswa mukugadzirwa kwemhando dzakasiyana-siyana castings; 2. Iyo dhayamita yegomba remukati rekukanda haina kururama, mukati megomba repamusoro rinenge rakashata, hutano huri hurombo, uye machining allowance yakakura; 3. Kukandira kunowanzoita kupatsanurwa kwesimba rinokwevera zvinhu pasi. Application: Centrifugal casting yakatanga kushandiswa kugadzira pombi dzakakandwa. Kumba nekune dzimwe nyika, centrifugal casting inoshandiswa musimbi, migodhi, yekufambisa, kudiridza, michina yemvura, ndege, kudzivirira kwenyika, motokari, uye mamwe maindasitiri kugadzira simbi, simbi, uye isiri-ferrous carbon alloy castings. Pakati pazvo, kugadzirwa kwezvakaita senge centrifugal cast iron pombi, mukati memoto injini silinda liners, uye shaft sleeve ndiyo inonyanya kuzivikanwa.
