H-type Double Knuckle Press

JNKJ-D Series

JNKJ 250D / 300D / 400D / 500D / 600D / 800D / 1000D / 1200D

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
▪ Intensive automatic circulation refueling device: Simultaneously with the operation of the press, it automatically supplies the right amount of oil at the right

Smart controller
It is designed to provide all operating information at a glance, from the size of the current press working load, the pressing speed per minute of the press (SPM), the operating temperature of the drive inside the press, and the operating load of the main motor.

Press to memorize the mold
If you press the preset mold number after changing the mold, the press adjusts the die height of the installed mold by itself, allowing you to quickly change the mold and prevent accidents caused by malfunctions.

Smart Road Monitor
The current, average, and peak values ​​of the load applied by the press are saved as data so you can check them whenever you need them.

Self-diagnosis and action guide
When an unexpected error occurs while the press is working, it is possible to find the cause and action method and guide the operator to take prompt action, prevent safety accidents and maximize productivity.

Equipped with smart manual
The press’s basic operation sequence is guided through visual effects, and if an incorrect operation is executed, it can be immediately checked, thereby preventing safety accidents due to malfunctions in advance.

Smart monitoring system
It supports a smart factory system that can remotely monitor press equipment status, work status, production quantity, and operating time.
