Vol.9 PARTS NAME OF STANDARD TOOLING

Turret punch press Tool is composed of several parts.
Also, the style of the tool varies depending on the machine to be used. This time, we summarized the part name and functions.

Thick Turret tooling

The thick turret tooling receives the pressing force of the press striker with the head, transmits the force to the punch body, and punches the workpiece with the punch edge and the die.
Also, after processing, the workpiece is held by the guide and stripper by the force of the spring, and the punch edge is pulled out.

EACH PART NAME AND FUNCTION OF TOOL

1. PUNCH BODY, DIE

2. STRIPPER

A part that holds the workpiece during processing.
After processing, the punch edge is pulled out from the workpiece at this part. (This is called a strip.)

3. GUIDE

Insert this part into the turret and hold and guide the punch body.

4. HEAD

Part that receives the force of the striker directly and conveys it to the driver and the punch body.　
In case of the small diameter tool, rotate it to adjust the punch length.

5. SPRING

Hold the workpiece during processing and pull the punch edge away from the work after processing.
Use coil spring, urethane spring, disc spring and so on.

6. DRIVER

MURATA TYPE TOOLING

The Murata type toolings transmits the pressing force of the press ram to the mechanically connected holder / punch body and punches out the workpiece with the punch edge and the die.
Also, after processing, the ram will forcibly pull up the holder.

Two types of Holders are as follows.

1. 114 Type (Urethane stripper type) ・・・ Low cost and simple structure.
2. Vulcan Type (Metal stripper type) ・・・ Designed for Strengthened stripping power compared to standard 114 Type.
