What is Swing Die(Swing Cam)？
Characteristic of the "Swing Die(Cam)"
- This is the mechanism of a rotary system cam that corresponded to do certainly
to stop rotation that is the weak point of a rotary system cam by using
the slide block and the swing block.
- It became to be able to set the Die mounted cam system on Swing cam system
as well because of that to became able to stop rotation by the slide block
and swing block.
For improvement SPM, it is not only to set cam driver up on Swing cam but also had done to become able to set cam driver up onto the lower die.
- It is to design that will be able to decide freely the slice line (division
line) between rotation side and fixed side and it become able to make distance
from fixed side with when rotation.
(It the matter that to move the center of the slice line from the pivot center of the rotation, is YB's patent)

What is Half Mount Cam？
What is Half Mount Cam？
The Half Mount system which patened on 2020 had developed as complete the rotation cam system. Following are those characteristics.
- Slide of the Half Mount 凸 side is consisted of high strength brass with
graphite and pre-hardened steel for improving abrasion resistance, and
凹 side is pre-hardened steel.
So it has become able to improve greatly the withstand load.
- Half Mount cam is, it has become able to adjust easily by shim plate so
on.
- Half Mount cam is, by keeping widely slide plate surface, become easy to
do centering of top and bottom, and became nothing to shift of left-right.
- Before, it had done to draw slice line of arc from rotation center when
decide the slice line between rotaition side and fixed side, so there was
a problem that tough matching adjustment.
But now, by it move the center of slice line of arc to inside, become able to the slice line of arc that make gap with when rotation.
- It will be taken the force of the press by the plate of Half mount and
the swinng die plate of front and behind.
- The cam system will be to become the flying cam system as a general.
- It was to become able to correspond the structure of mold die that to not need air cylinder by that the positive set and the lift pin of spring style.
- Our cam systems are able to do bend at once whole circumference of flange
area, but other cam system need two mold die operation the same process.
- The continuous bending to whole circumference of flange area of HOOD OTR by the Half Mount cam system. (no air cylinder)
The video; a example of the movement of
Swing die and Half Mount cam.
At here, it has exhibited the video that a example of the movement.
You are able to watch the video if you click the car button.
■The video ① The representative example video of Swing die (cam). ⇒ 
(Please click the car button.)
It is the system which has the function to stop rotation steadily. It is
able to forming even if the axis of rotation far from the panel.
For this reason, it was to become able to reduce a number of the press
mold process due to combine of Swing die.
Our company have developed and done standardization this system by continuing
to have repeated improvement more than 15 years.
■The video② R slice video behind the fixed side by swing die system ⇒ 
(Please click the car button.)
By eccentricity of the R slice with the center of rotation, the slide is
eliminated and the alignment is ensured.《YB Patent》
R slices can be adapted to the product shape.
■The Video③ The drop style Swing cam ⇒ 
(Please click the car button.)
This is a cam system used for the body side outer, which is the most important
part of the outer panel frame of the vehicle.
This cam system’s used location will be used to tough cross section structure
of the front pillar area.
■The video④-1 Half-mount-cam R slice- system ⇒ 
(Please click the car button.)
This is an improved version video of the traditional cylindrical cam system.
The slide surface can be oil-free slide with the R surface. The processing
is flat surface processing.
Sliding with a fixed punch is no longer required.《YB patent》
■The video④-2 Half-mount-cam Air cylinder operation ⇒ 
(Please click the car button.)
It is possible to design and manufacture taraditional mobile dies more
compactly.
The bearing is just a fall prevention when the mold is reversed.
■The video⑤ Swing extension system ⇒ 
(Please click the car button.)
This system enables processing in one process at each location for products with different cam directions.
■The video⑥ HOOD OTR Swing 1 bending video ⇒ 
(Please click the car button.)
This die has a cam driver fixed to the lower body. Each swing die has a
mechanical positive set sytem.
This makes it possible to reduce the weight of each swing die, reduce the
moment of inertia, and improve the SPM.
