Hanil KNUCKLE PRESS |
General
KNUCKLE PRESS |
LINK MOTION PRESS |
LINK-KNUCKLE PRESS |
Use |
Universal press molding |
Professional Cold Forging |
Drawing |
Specially designed to perform drawing and Cold Forging at the same time |
Able to produce high-value-added precise parts |
|
Universal press molding |
Progressive Cold Forging |
|
|
Highly efficient productivity |
|
|
Strength |
High productivity/ 2-3 times of universal |
Suitable for concentrated load of small-sized products |
Higher productivity compared to hydraulic press |
|
Uses "H" TYPE double skin steel on the side to prevent deforming frame |
|
May hold larger molds as operating frame can expand and insert bolster |
|
Broad bolster for professional molding |
|
Suitable for producing automotive parts |
|
Significantly decreases noise |
|
|
|
Extends the lifespan of molds |
|
|
|
Strong against Eccentric Load as Screw Point is in flat shape and maintains precision at Knuckle Press' Bottom Dead Center |
|
|
|
Bottom Dead Center is long from 150¡Æ to 210¡Æ and shows the symmetric speed of Bottom Dead Center |
|
|
|
Weakness |
Cannot increase Slide Stroke over a certain level |
Reduces productivity (approx. 50 SPM) |
Reduces productivity and causes noise |
Cannot increase Slide Stroke over a certain level |
Cannot install large professional mold |
Low capacity |
Slide-controlling Screw Point is in the Ball shape and may be distorted by a small eccentric load to affect precision in Bottom Dead Center of Knuckle Press |
The slide to trigger link motion cannot be forged and is at high risk of mechanical damage and wearing in forced operation |
|
Cannot form the speed curve for constant velocity in Bottom Dead Center due to the mechanical properties of link motion |
Motivation |
To improve the popularity and productivity of precise press as ordinary Knuckle Press lowers productivity and cannot hold large molds |
Small products' concentrated load forging |
To improve productivity when performing hydraulic drawing |
To improve the weakness of link motion and increase productivity by allowing drawing and Cold Forging |
Professionally manufactured Knuckle Press since establishment to hold a number of patents |
