C-type mechanical presses JH21
Advantages
The body of JH21 series press is welded with steel plate,so it is with good rigidity and stable precision.The crankshaft is placed lengthways,so the structure is compact and the contour beautiful. Using the combined pneumatic friction clutch and brake,so the engagement is smooth,the action agile,and the noise low.
Gear pair adopts the flooding system lubrication.The slide block is six-face rectangle with longer guide track whose face is bronze panel.Meanwhile an import hydraulic overload protector is installed in the slideblock whose air pump and high pressure ring seal are imported from other country.Its action is agile and reliable.
The die set is adjusted by motor over JH21-63 press.There set lifting balance cylinder at the slideblock over model JH2I-4O press,whose ring seal is imported from other country.The air pipeline is controlled by safety duplex valve.
Its electric circuit is controled by import PLC.The press can be equipped with air cushion, automatic feed shaft and photoelectric protector,and can be equipped with various automatic equipment which conform to the safety standard of press.
