TRUMPF Type Size I OB9×20 Obround Punch Tooling

The TRUMPF Type Size I OB9×20 Obround Punch Tooling is designed for precision sheet metal punching applications using the TRUMPF-style Size I tooling system. It is suitable for manufacturers requiring reliable punching performance as well as flexible customization of hole sizes and punching profiles.

The tooling shown on this page is an OB9×20 obround punch manufactured as a representative sample of our TRUMPF Type Size I punch tooling capabilities. In this specification, OB represents an obround profile, while 9 × 20 mm indicates a finished punching profile approximately 9 mm wide and 20 mm long.

The OB9×20 specification is used as an example only. We manufacture custom TRUMPF Size I punch tooling in different dimensions and geometries according to customer drawings, required hole profiles, sheet materials, material thicknesses and actual punching applications.

In addition to conventional round, square, rectangular and obround punching tools, a wide range of special-shape punch tooling can be manufactured for complex sheet metal components.

Technical Specifications

What Does OB9×20 Mean?

OB9×20 identifies the punching profile and dimensions of the sample tooling shown on this page.

OB stands for obround, a profile consisting of straight sides combined with rounded ends. It may also be described as an oblong or elongated hole profile in sheet metal fabrication.

For this sample:

• 9 mm = profile width
• 20 mm = overall profile length

An obround punching tool can be used to produce elongated openings for mounting, positioning, adjustment and assembly applications.

The OB9×20 size is only a demonstration specification. Different widths, lengths and profile proportions can be manufactured according to customer requirements.

Standard & Custom Punch Shapes

Our TRUMPF Type punch tooling is not limited to the OB9×20 profile shown in the product photographs.

In addition to common punching geometries such as RO (round), SQ (square), RE (rectangle) and OB (obround), we can manufacture a wide range of special-shaped and custom punch tooling for different sheet metal applications.

The shape chart shown below presents examples of commonly available and customized punching profiles.

Examples of standard and custom punch shapes available for TRUMPF Type punching tooling.

The profiles illustrated in the chart are examples rather than the complete range of tooling we can manufacture. If the required punching geometry is not shown, customers can provide a drawing of the hole, profile or finished sheet metal component for evaluation.

Available punching profiles can include:

• Round holes
• Square holes
• Rectangular holes
• Obround and elongated holes
• Slot profiles
• Polygonal profiles
• Keyhole-type profiles
• Notching profiles
• Irregular contours
• Special punching geometries
• Customer-specific profiles manufactured from drawings

This flexibility makes custom TRUMPF punch tooling suitable for sheet metal parts where standard round, square or rectangular punches cannot meet the required geometry.

Custom Sizes and Tooling Design

The size and shape shown on this page are for demonstration purposes and do not represent a fixed product specification.

Customers can provide the required punching dimensions directly or send us a DXF, CAD drawing or finished-part drawing. Based on the actual application, we can manufacture the punch tooling according to the required profile and dimensions.

Customizable items can include:

• Punching profile
• Hole width and length
• Special profile geometry
• Punch and die dimensions
• Die opening
• Die clearance
• Tooling configuration
• Application-specific punching features

Die clearance can be selected according to factors such as sheet material and material thickness, helping match the punch and die configuration to the actual punching application.

Typical Applications

TRUMPF Type Size I punch tooling can be used for precision hole and profile punching across a wide range of sheet metal fabrication applications, including:

• Electrical cabinets and switchgear
• Control panels
• Sheet metal enclosures
• Machinery covers and guards
• Metal cabinets
• HVAC components
• Equipment housings
• Automotive sheet metal components
• Industrial panels
• Mounting plates and brackets
• Custom fabricated sheet metal parts

The OB9×20 obround punch shown here is particularly suitable for components requiring elongated openings for mounting, positioning, adjustment or assembly.

For components requiring more complex geometries, special-shape punch tooling can be designed according to the actual workpiece profile.

Custom TRUMPF Punch Tooling from Your Drawing

For non-standard punching applications, customers do not need to select only from existing standard shapes.

Simply provide us with your workpiece drawing, required punching profile, dimensions, sheet material and material thickness. Our engineering team can evaluate the application and provide a suitable custom punch tooling solution.

We support the manufacture of both conventional and custom TRUMPF Type punching tools, from simple round, square, rectangular and obround profiles to complex special shapes.

This drawing-based customization service helps sheet metal manufacturers obtain tooling that more closely matches their actual components and production requirements while expanding the possibilities of TRUMPF punching machine applications.
