H type double knuckle press (Patent No. 0368009)Precision transfer, 2 points suitable for progressive medium / object parts processingKnuckle press. It is suitable for precision large-capacity machining by inheriting the authentic knuckle press method of the 3-point free link joint method.

Feature

The slide stops while maintaining the pressing force on the bottom dead center, maximizing the formability of the material and the shear surface is also excellent.

▪ Strong frame: Maintains JIS level 1 accuracy even when intensive stress occurs in the center of the frame during shearing, compression, drawing, etc.
▪ Optimized for transfer and progressive processing: Optimized design for automated multi-process operation with 2POINT knuckle press
▪ Use of special medal on the link: Guarantee the life of the link by applying our own special material metal alloy
▪ With locking device: After adjusting the slide, the gap of the upper slide is always maintained at zero (0).
▪ External air clutch brake: Easy repair and repair with external air clutch brake
