Product Guide
Application Scenarios+
Flanged punch holders are used in precision punch tooling where repeatable punch positioning is critical during setup, troubleshooting, and maintenance. In automotive connector and terminal forming trials, they help engineers dial in punch location while keeping the punch seating stable, which is especially useful when fine alignment affects contact geometry.
They are also suited for plate hole rework in electronics and thin-gauge stamping lines. When plate holes become worn or slightly mispunched, this holder style supports controlled replacement and alignment of round punch features, reducing the need for immediate in-house plate fabrication.
For key flat shank punches, the flanged interface provides a secure mounting reference for fine punch details, helping maintain consistent punch-to-die relationship across iterative trial adjustments. The available geometry range (V/H 20–30 mm) and punch diameter coverage (10–16 mm) makes this variant adaptable to common shop-floor punch sizes.
- Trial setups and tuning for round and key flat shank punches
- Replacement of worn plate holes and correction of mispunched rounds
- Stable punch plate mounting for repeatable alignment in maintenance cycles
Material & Process Details+
The provided product data specifies dimensions and punch type compatibility (round punch and key flat shank punches), but it does not include a steel grade, heat treatment state, or hardness values. Therefore, no specific material-property claims (e.g., HRC, wear resistance, or toughness) can be stated from the input.
When selecting a punch holder steel for high-cycle punching, engineers typically match the holder material to the punch’s loading and abrasive wear environment. Common practice is to use wear-resistant tool steels and apply heat treatment such as quenching and tempering, or nitriding when surface wear and fatigue resistance are key.
- Data not provided: steel grade, nitrided layers, or hardness (HRC)
- Selection guidance: confirm compatibility with the punch material and operating load to balance wear resistance vs. toughness
Sizing & Selection Guide+
Use the specified geometry ranges to match the holder to your punch and your punch plate layout. This flanged holder supports two specification types: for round punch and for key flat shank punches. Start by selecting the correct punch type, then confirm the punch diameter D within the available ranges: 10 mm, 10–13 mm, or 13–16 mm.
Next, verify the outer shape dimensions. The outer shape variables V and H are each available at 20, 25, or 30 mm, so choose the V/H combination that matches the recess or mounting envelope in your punch plate.
For length matching, use the fixed L of 30–40 mm and select the full length alteration LC in the available ranges: 25–29 mm or 31–39 mm. If your mold design requires tight repeatability across trial adjustments, ensure your punch plate positioning and any related tolerances are consistent with the selected V/H and LC geometry.
- Configurable: V (20/25/30), H (20/25/30), D (10 / 10–13 / 13–16), LC (25–29 / 31–39)
- Fixed: L = 30–40 mm
Frequently Asked Questions
How do I choose between “round punch” and “key flat shank punch” configurations for these flanged holders?+
Match the holder Specification to your punch shank geometry: select “For round punch” when your punch is round, or “For key flat shank punches” when the punch uses a flat key shank reference. The holder is intended to provide controlled positioning for trial setups and fine detail alignment, so using the correct configuration helps prevent seating misalignment.
Which punch diameter (D) range is supported by this flanged punch holder series?+
The supported D (punch diameter) ranges are listed as 10 mm, 10–13 mm, and 13–16 mm. Select the D range that includes your punch diameter to ensure the holder interfaces correctly during setup and rework.
What outer shape dimensions (V and H) do I need to match in my punch plate design?+
The outer shape variables are V = 20, 25, or 30 mm and H = 20, 25, or 30 mm. Choose the V/H values that fit the mounting envelope or recess geometry in your punch plate so the flanged holder sits with the intended reference dimensions.
How should I select L and LC when adjusting punch positioning for trial setups?+
L is fixed at 30–40 mm, while LC is available as 25–29 mm or 31–39 mm. Pick LC based on the required full length alteration for your stack-up so the punch height and seating position match your trial alignment targets.
Can these flanged holders be used to replace worn punch plate holes or correct mispunched rounds?+
Yes. The intended use includes replacing worn punch plate holes and correcting mispunched rounds. By selecting the correct punch type (round vs. key flat shank) and matching D, V/H, and LC to your plate layout, the holder can support controlled re-alignment during maintenance.
