Lub punch xovxwm yog qhov tseem ceeb ntawm cov xovxwm stamping. Nyob rau hauv lub teb chaws ntau lawm, stamping tshuab yog nce lug siv vim nws qhov zoo ntawm cov tsoos machining: txuag cov ntaub ntawv thiab lub zog, high efficiency, qis tus neeg teb xov tooj kev xav tau, thiab muaj peev xwm los tsim cov khoom tsis yooj yim sua los ntawm lub tshuab los ntawm ntau yam pwm.
Stamping ntau lawm feem ntau tsom rau cov ntawv hlau. Siv cov pwm, nws tuaj yeem tsim blanking, xuas nrig ntaus, sib sau, sib sib zog nqus nqus, trimming, nplua blanking, shaping, riveting, thiab extruded qhov chaw, thiab lwm yam, nrog rau kev siv dav hauv ntau yam. Piv txwv li, ntau yam khoom siv hauv peb lub neej niaj hnub, xws li cov keyboards thiab qhov (socket), khob, txee, phaj, rooj plaub hauv computer, thiab txawm tias cov cuaj luaj thiab dav hlau, tuaj yeem tsim tau siv cov punch presses thiab pwm.
Tus tsim ntawm ib tug punch xovxwm converts voj voog mus rau hauv linear tsab ntawv tsa suab. Lub hwj chim yog muab los ntawm lub ntsiab lub cev muaj zog, uas tsav lub flywheel, uas nyob rau hauv lem drives gears, ib tug crankshaft (los yog eccentric iav), thiab txuas rods ntawm ib tug clutch, ua kom tiav cov linear suab ntawm lub swb thaiv. Cov lus tsa suab los ntawm lub ntsiab lub cev muaj zog mus rau tus pas nrig txuas yog ncig.
Yuav tsum muaj ib qho kev hloov pauv ntawm tus pas nrig txuas thiab cov slider rau kev ncig thiab kab tawm. Feem ntau muaj ob hom mechanisms nyob rau hauv no tsim: ib tug spherical hom thiab ib tug pin hom (cylindrical hom). Qhov no mechanism converts lub voj voog mus rau hauv txoj kab ncaj nraim ntawm lub slider. Lub punch xovxwm siv lub siab rau cov khoom, ua rau nws mus rau plastically deform thiab tau txais cov duab thiab precision. Yog li ntawd, nws yuav tsum tau siv nrog ib txheej ntawm tuag (sab sauv thiab qis tuag) los tso cov khoom ntawm lawv. Lub tshuab siv lub siab los deform cov khoom, thiab cov tshuaj tiv thaiv los ntawm lub zog siv rau cov khoom thaum lub sij hawm ua yog absorbed los ntawm lub punch xovxwm nws tus kheej.
