EACH NAMES OF FORMING TOOL
When forming processing by a turret punch press, adjustments different from punching is required.
This time, We summarized the part names and functions of forming tool and how to adjust the tool.

UPWARD FORMING TOOL
Upward forming is a process that forms from the down side of the workpiece upward.

EACH PART NAMES AND FUNCTIONS OF
UPPER TOOLING (PUNCH SET)
① EMBOSS PUNCH

A part that directly forms a workpiece.

TOOLING STRUCTURE (NC 1-1/4)
1～1.5mm② EMBOSS BODY

A part that holds the emboss punch.

③ UPPER EJECTOR

Head fixing bolt
Head

A part to eject formed shape after processing.
In addition, there are also cases in which the workpieceis formed as an aid.

④ HEAD

The part that directly receives the force of the striker andtransmits it to the embossed body and punch.
Also, adjust the punch length to determine the rising heightof the forming shape.

Emboss Body

How to adjust the punch length. (Height Adjustment)
1. Loosen the head fixing bolts.
2. Rotate the head and adjust length of punch.
(Clearance between upper head and lower head keep 1mm to 1.5mm.)
3. Fasten the head fixing bolts equally.

EACH PART NAMES AND FUNCTIONS OF
LOWER TOOLING (DIE SET)

Lower Ejector⑤ DIE PUNCH

A part that directly forms a workpiece.

⑥ LOWER EJECTOR, SPRING

During processing, hold the workpiece, and after processing,push up the lower ejector by the force of the spring and pull theworkpiece away from the die punch.

⑦ STRIPPER BOLT

A part that connects the die punch and the lower die ejector.

Height of forming tool die tends to be higher than standard
tool die. For that reason, it scratches a material or forming
part would be hit to Upper Turret. Appropriate processing
method and programing are needed.

PARTS NAME OF STANDARD TOOLINGDOWNWARD FORMING TOOL
Downward forming is a process that forms from the top of the workpiece downward.

EACH PART NAMES AND FUNCTIONS OF
UPPER TOOLING (PUNCH SET)
For the part names and functions of the upper tooling, refer to“PART NAMES OF THE STANDARD TOOLING” (Vol. 9).
The method of adjusting the punch length depends on thetool structure.

TOOLING STRUCTURE (NC 1-1/4)

METHOD OF ADJUSTING PUNCH LENGTH FOR Fig.1
1. Attach cap screw to the two bolt holes and tighten evenly.
2. Rotate the head by the belt wrench and adjust the punchlength.
3. Remove the cap screw.

HeadSpringDriver

METHOD OF ADJUSTING PUNCH LENGTH FOR Fig.2
1. Loosen a punch fixing bolt.
2. Remove a punch body from a guide and put shims on
between the punch and driver.
3. Install the punch body and fasten the punch fixing bolt.
<NOTE>
When making fine adjustment, first adjust with die-shim,
remove the die shim after the adjustment is finished,
you can easily adjust by using the same thickness punch
shim to punch side.

③ SPRING

Push up the ejector.

IMPORTANT NOTICE
1. Use in a predetermined machining conditions.
Excessive load may be applied to the tool and damage may be caused if the punchoverall length is increased for use other than the specified plate thickness (material)or to raise the rise higher than the predetermined tooling dimension.
2. Even for presses of the same model, the shut height differs for each machine, so pleaseadjust the appropriate punch length.
※At shipment from factory, we set the punch length shorter for safety.
