JFY Type D Station RO15.1 Thin Turret Round Embossing Tool

The JFY Type D Station RO15.1 Thin Turret Round Embossing Tool is a specialized sheet metal forming tool developed for creating a nominal Ø15.1 mm circular emboss in 2 mm thick sheet material.

Unlike conventional punching tools that cut and remove a slug, this embossing tool plastically deforms the sheet between a matching male and female forming section. The material is displaced into the designed cavity to create a raised or recessed circular feature while remaining part of the workpiece.

The tooling shown consists of a complete upper and lower forming-tool combination. During the machine stroke, the male forming section progressively pushes the sheet into the corresponding female cavity. Correct coordination between the two components controls the emboss diameter, forming height, wall transition and surrounding sheet flatness.

“RO15.1” identifies the nominal round emboss profile with a diameter of 15.1 mm. It should not automatically be interpreted as the size of every internal tooling component. The male and female forming dimensions must include the appropriate forming gap, corner radii and material allowance for the specified 2 mm sheet.

This product uses a D Station thin turret configuration, providing the installation space and structural support required for the forming assembly. Compatibility must still be checked using the exact punch press model, existing tooling dimensions and station structure.

The standard application described here is designed around 2 mm sheet thickness. If the material type, thickness or mechanical properties change, the forming clearance and profile may also need to be redesigned. A tool manufactured for one application should not automatically be used on a substantially different material or thickness without engineering confirmation.

WYS Machinery can customize the emboss diameter, forming height, forming direction, transition radius, relief, tool material and installation structure according to the customer’s machine and finished-part drawing. Free tooling design support is available for custom sheet metal components.

This tooling is manufactured by WYS Machinery as compatible replacement tooling. References to JFY describe the applicable tooling configuration and do not imply original manufacture, authorization or official affiliation.

Technical Specifications

How the Embossing Tool Works

The RO15.1 embossing tool creates a three-dimensional circular feature through controlled plastic deformation.

The forming process generally includes:

• The sheet is positioned between the upper and lower forming components
• The punch press initiates a controlled forming stroke
• The male section pushes the sheet toward the female cavity
• Material flows around the designed transition radius
• The matching profile controls the emboss diameter and height
• The tool retracts and releases the formed component

Because the process forms rather than cuts the material, the tool normally does not create the conventional round slug produced by a piercing punch.

The final shape depends on the tooling geometry, sheet material, thickness, machine stroke and material springback.

RO15.1 Emboss Dimensions

RO15.1 represents the nominal Ø15.1 mm emboss profile specified for the finished sheet metal component.

A complete emboss specification should include more than diameter. Important dimensions include:

• Emboss outside diameter
• Emboss height or depth
• Top diameter, if applicable
• Transition radius
• Side-wall angle
• Forming direction
• Sheet thickness
• Distance from the emboss to nearby holes or edges

Since only the Ø15.1 mm diameter and 2 mm sheet thickness are currently specified, the emboss height and detailed profile should be confirmed from the customer’s drawing before manufacturing.

Suitable for 2 mm Sheet Thickness

This tooling configuration is designed for a nominal sheet thickness of 2 mm.

The actual tool geometry must consider:

• Sheet material
• Actual thickness tolerance
• Tensile strength
• Yield strength
• Elongation
• Surface condition
• Rolling direction
• Required emboss height
• Required surface quality

A 2 mm mild-steel sheet and a 2 mm stainless-steel sheet do not necessarily require exactly the same forming geometry or machine settings. Material information should therefore be provided when ordering.

Raised and Recessed Embossing

Depending on the installation direction and finished-part requirements, a round emboss may appear as:

• A raised feature on the upper surface
• A raised feature on the lower surface
• A recessed circular feature
• A support dimple
• A locating or spacing feature

The customer should identify the viewing side of the component and clearly mark the emboss direction on the drawing.

If upward and downward embosses are both required, separate tooling configurations or an appropriate reversible design may be needed depending on the machine and tooling structure.

Emboss Height and Forming Limits

The emboss height must be selected according to the diameter, sheet thickness and formability of the material.

Excessive forming height may cause:

• Material thinning
• Surface cracking
• Distortion around the emboss
• Tearing at the transition radius
• Excessive forming force
• Tool interference
• Difficulty releasing the workpiece

A suitable transition radius and controlled forming depth help distribute strain more evenly.

WYS Machinery can evaluate the proposed emboss height after receiving the finished-part drawing and material information.

Forming Clearance

Embossing-tool clearance is different from the cutting clearance used for ordinary punch-and-die sets.

For a cutting tool, clearance is selected to control fracture and slug separation. For an embossing tool, the gap between the male and female profiles must allow the 2 mm sheet to flow and form without being excessively squeezed or trapped.

Forming-clearance design considers:

• Sheet thickness
• Material type
• Material strength
• Material elongation
• Emboss diameter
• Required forming height
• Transition radius
• Surface-quality requirements
• Material springback
• Tool release requirements

Incorrect forming clearance can cause excessive thinning, scratches, cracking, uncontrolled dimensions or difficulty separating the sheet from the tool.

Forming Force and Machine Settings

Required forming force depends on:

• Sheet material
• Sheet thickness
• Emboss diameter
• Forming height
• Transition radius
• Tool geometry
• Material strength
• Machine stroke
• Forming speed

Even though this is a D Station tool, physical installation capacity does not by itself confirm that the forming operation is suitable. Available machine tonnage, stroke control and shut-height settings must also be checked.

The tool should be commissioned using a controlled trial stroke. The forming depth should be increased gradually until the required emboss height is achieved.

Typical Applications

The RO15.1 D Station embossing tool can be used in:

• Electrical cabinets and control enclosures
• Switchgear panels
• Electronic equipment housings
• Sheet metal mounting plates
• Machinery guards
• Automotive sheet metal components
• HVAC components
• Metal furniture
• Stainless steel equipment
• Industrial control panels
• Brackets and support plates
• General precision sheet metal fabrication

Typical emboss functions include:

• Increasing local panel stiffness
• Creating spacer or support points
• Providing locating features
• Improving component positioning
• Creating screw or assembly seats
• Producing clearance around components
• Creating decorative circular features
• Improving sheet metal structure without adding separate parts

Structural and Functional Advantages

A properly designed emboss can provide additional functionality without welding or installing a separate component.

Potential benefits include:

• Increased local rigidity
• Improved sheet positioning
• Reduced need for separate spacers
• Repeatable assembly location
• Fewer secondary operations
• Improved component clearance
• Integrated functional features
• Consistent production on CNC punch presses

The actual structural benefit depends on the emboss dimensions, sheet material and surrounding component design.

Surface Quality and Part Flatness

Embossing causes local material displacement and may influence the flatness of the surrounding sheet.

To improve forming quality, the tool design should consider:

• Smooth forming surfaces
• Appropriate transition radii
• Correct forming clearance
• Controlled stroke depth
• Adequate distance from sheet edges
• Adequate distance from nearby holes
• Material rolling direction
• Workpiece support
• Tool lubrication, where appropriate

If the emboss is positioned too close to an edge, bend line or existing opening, surrounding distortion may increase.

Manufacturing Quality

The embossing tool is manufactured using controlled machining, heat treatment, precision grinding and assembly processes.

Quality inspection can include:

• Male forming-profile measurement
• Female cavity measurement
• Emboss-diameter verification
• Forming-clearance inspection
• Transition-radius inspection
• Tool concentricity checking
• D Station dimensional inspection
• Tool-height inspection
• Forming-direction confirmation
• Surface-finish inspection
• Assembly and movement testing
• Trial forming where required

Accurate matching of the upper and lower profiles helps control the emboss dimensions and reduce uneven forming loads.

Installation and Trial Forming

Before installation:

• Confirm the exact punch press model
• Verify the D Station tooling structure
• Confirm the RO15.1 profile
• Check the sheet material and 2 mm thickness
• Confirm the required emboss direction
• Confirm the target emboss height
• Inspect the upper and lower forming surfaces
• Clean the tooling and station
• Confirm tool alignment
• Check machine stroke and shut height

During trial forming:

• Start with a conservative forming depth
• Use a test sheet matching the production material
• Increase forming depth gradually
• Measure the emboss diameter and height
• Inspect for cracking and thinning
• Check surrounding sheet flatness
• Confirm that the workpiece releases smoothly
• Save the verified CNC and machine settings

The tool should not be tested initially at maximum forming depth without confirming the setup.

Maintenance

Regular maintenance should include:

• Cleaning the male and female forming profiles
• Removing metal particles and material residue
• Inspecting the transition radii
• Checking for surface scratches or galling
• Inspecting tool alignment
• Checking moving or spring-loaded components
• Applying suitable lubrication where required
• Inspecting screws and retaining components
• Protecting the forming surfaces during storage

Unlike cutting tools, embossing tools are not normally maintained only by sharpening a cutting edge. Wear, surface damage and dimensional change of the complete forming profile must be evaluated.
