Hauv nruab nrab thiab thaum xaus xyoo 1940, tsuas muaj ob peb lub teb chaw tuaj tuag-tshuab ua kom tuag lub sijhawm tam sim no, suav nrog: British me me pneumatic kub lub tshuab cua kub (Shanghai), Czech Polak 600 (clamping quab yuam 76 t) ntsug txias chamber tuag casting tshuab (Kunming) thiab kab rov tav txias kab rov tav tuag siv lub tshuab (Chongqing) nrog lub zog tuav ntawm 100 t los ntawm KUX, Asmeskas.
Xyoo 1950, kuv lub teb chaws tsim thiab tsim lub tshuab hluav taws xob puv hydraulic 50-hom kab rov tav txias-chamber tuag-casting tshuab nrog clamping quab yuam ntawm 500 kN thiab 1000 kN. Lub sijhawm ntawd, Polak ntsug txias chamber tuag casting tshuab los ntawm Czech koom pheej tseem tau ua ntshuam hauv pawg. Muaj 4 qhov tshwj xeeb, qhov siab tshaj plaws clamping quab yuam yog 2 200 kN, kab rov tav txias txias tuag tshuab ntawm lub qub Soviet Union, toggle clamping, Peb qhov tshwj xeeb, qhov siab tshaj plaws clamping quab yuam yog 5 300 kN. Thaum xyoo 1960, peb pib tsim cov khaub thuas ntsug txias tuag casting tshuab thiab kab rov tav txias ua cua tshuab tuag, uas yog tus qauv 900 (clamping quab yuam 1 150 kN) thiab J 1113 (clamping force 1 250 kN). Xyoo 1970, txhawm rau txhim kho cov khoom lag luam, cov koom haum Jinan ntawm Casting thiab Forging Machinery tau teeb tsa, nrog kev koom tes ntawm Shanghai Technology Research Institute thiab Shanghai Die Casting Machine Factory, los koom ua ke qee yam kev ua haujlwm sib raug: cov koob ntawm cov dhau los tuag casting tshuab Tsim Tsim thiab sim mus sim J 1125, J 1140 thiab J1163 tag nrho hydraulic kab rov tav txias txias ua lub tshuab tuag casting; tsim thiab tsim tag nrho hydraulic kab rov tav txias chav cua tuag casting tshuab nrog clamping quab yuam ntawm 4 000 kN (Shanghai Forging Machine Tool Works Raug); rau xyoo 1980 thiab thaum ntxov xyoo 1990, cov ntu tseem ceeb txuas ntxiv ua kom tiav txoj kev txhim kho ntawm cov kab rov tav ntawm lub tog raj kheej txias tuag-tshuab tshuab nrog lub zog tuav hauv qab 16,000 kN; ntsug txias-chamber tuag-casting cav kuj tsim lub clamping force Series khoom hauv qab 2 500kN; Nyob rau xyoo 1986, thawj lub tsev J1163 Ib chav tsev tuag-ua haujlwm tsis siv neeg tau raug sim-tsim; thawj lub cev hloov tau tuag-casting chav tsev tau tsim nyob rau xyoo 1990, nrog lub zog clamping ntawm 4 000 kN; nyob rau hauv cov nqe lus ntawm tuag-casting tshuab tsim ua hauj lwm, Nyob rau hauv 1980s, tsim qauv txhaj tshuaj ntawm tuag-casting tshuab tau ze rau theem txawv teb chaws lub sijhawm ntawd; nyob rau hauv cov xyoo tom ntej no, cov twj pabcuam thiab cov khoom siv ntsuas hluav taws xob tau muab tso ua ke thiab ua tiav thiab cov khoom tsim tau. Lub tshuab clamping yog txhua yam tsav hydraulic, thiab toggle mechanical extension quab yuam qauv hloov lub zog hydraulic tag nrho. Lub sijhawm ntawd, chav kub tuag tuag tshuab kuj tsim ua cov khoom siv nrog lub zog clamping ntawm qis dua 1,500 kN, thiab lub tshuab ntsug tuag ntsug tshuab kuj tau muaj cov khoom lag luam nrog lub zog clamping ntawm 3 150 kN.
Txhawm rau txhawb ntxiv qhov kev txhim kho ntawm cov tshuab ua kom siab tuag-tshuab ua kom tiav, thawj tuag-casting tshuab parameter qauv tau tsim nyob rau xyoo 1980. Xyoo 1990, thaum lub tshuab tuag-casting tshuab parameter qauv tau hloov kho thiab hloov dua siab tshiab, thawj tuag- casting tshuab raug thiab cov txheej txheem kev mob raug tsim. Ua tus qauv, tsim khoom thiab lees txais kev tuag tuag tshuab muaj qhov ua raws (lossis siv).
