Product Description

The machine body is welded with steel plate which has been through tempring and shot cleaning, so the press feature high rigidity and accuracy.
With crankshaft which has been through chilling and polishing long itudinally arranged, the machine features nice appearance, compact construction and good facility,
Double pneumatic cylinder counter balancing the weight of the slide and can reduce the upper mold impact and noice, so as to eliminate the clearance between the connecting rod and slie.
By means of the PLC and pneumatic controls, this machine can carry out various actions. Through the universal selector switch, it can perform the following action: 1> inching, 2> single stroke, 3> continual punching, 4> emergency stop.
The key components, such as slide, guideway, bolster and connecting rod are used high intensity cast-iron with rasin sand structure. Comparing with common cast-iron with loam sand structure, their surface have 1~2 degree improved, and roughness will 2-3 degree improved.
The types over 60T are equipped with brake motor which can adjust the die set height automatically. The machine adopts import components such as pneumatic components, electrical components and seal rings.
Wet friction clutch, dry friction clutch, hydraulic overload protection device, cave-in protection device are available.
Automatic lubrication, opto-electronic protection, and air ejector are optional components.
