Thick Turret Basic Type D Station

Desctription:
The basic tooling of a punch consists of several key components, including the punch, die, stripper plate, guide pins, punch holder, and die button. These components work together to provide precise and efficient punching operations. Proper alignment and maintenance of these components are crucial for achieving high-quality results and extending tool life.

Thick Turret Basic Type Basic Type D STN Guide Assembly

Product Description

The D station of Basic Type Thick Turret Tooling is a heavy-capacity tooling assembly designed for large-scale punching, with a maximum diameter of 3.500" (88.9mm). In the "Original" or "Standard" configuration, it is a massive, fully guided unit that emphasizes structural stability over the bells and whistles of modern adjustable systems.

Key Features

1. Structural Composition

The Original D Station is characterized by its weight and the "Long Tool" design. Its primary components include:

*The Punch Driver (Head): A large-diameter steel cap that receives the impact from the machine's hammer. In the Original style, this is a solid interface that does not rotate for adjustment.

*Disc Spring Stack: Due to the large surface area of a 3.5" punch, the "stripping force" required to pull the tool out of the metal is immense. The D station uses a robust stack of Belleville disc washers rather than coil springs to provide high-tonnage pressure.

*Full-Length Guide Body: The guide is a precision-machined cylinder that houses the punch. Its length ensures that even if the punch is hitting off-center, the tool does not tilt or "cock" inside the turret, protecting the station's alignment.

2. Manual Length Compensation

Because the "Original" type lacks a "click-adjust" head, maintaining the tool length after sharpening is a manual process:

*Shimming the Tail: When the punch tip is reground, the operator must disassemble the unit and place large-diameter punch shims (usually 0.5mm to 2.0mm) between the punch body and the driver.

*Fixed Penetration: Without shims, a reground punch will not reach the die, resulting in a "half-cut" or a jammed sheet. The solid shim-stack ensures that the punching energy is transferred directly without the "play" sometimes found in threaded adjustment systems.

3. Keying and Positioning

*External Orientation: The guide body features a standard keyway (typically at 0°) to align it within the turret.

*Internal Orientation: For shaped punches (like a 2" x 3" rectangle), the punch body itself is keyed to the guide. In Original D stations, this is often a fixed-key setup, meaning the tool is dedicated to one specific angle relative to the turret.
