Metric XVP Coated Center Dowel Punches for Heavy Load

Metric center dowel punches for heavy-load tooling are used to reference and stabilize workpiece position during repeated press cycles, especially in progressive dies and alignment-critical stamping operations. The heavy-duty center locating geometry helps maintain consistent pointing performance even when loads rise across long production runs.

• Progressive stamping and carrier dies: Use the chosen tip shape (X, R, K, O, H, L, J, N, V, Y, Z) to match receiver/guiding features and reduce misalignment under load.
• Automotive-grade bracket and connector housings: The XVP coating supports wear resistance at the locating interface, helping retain accurate alignment as cavity components cycle.
• Die maintenance and component replacement: Metric shank diameters (D = 10–25 mm) and point length ranges (L1 = 13–25 mm) simplify replacement while preserving center positioning geometry.

This variant’s XVP coating and heavy-load locating design make it well-suited for tooling where alignment drift and point wear directly affect part dimensional stability.

The provided configuration specifies an XVP coated center dowel punch, with the emphasis on coating-driven wear performance at the locating tip. While the exact base steel grade and heat-treatment condition are not listed in the input data, the intent of XVP for punch interfaces is to improve surface wear resistance and help maintain pointing performance over repeated cycles.

• Wear vs. toughness balance: Locating punches experience high contact pressure at the point; a harder, wear-optimized surface (via coating) supports dimensional stability while the underlying body maintains necessary toughness for repeated mechanical loading.
• Coating impact: XVP coating is selected to reduce point and edge wear that can lead to alignment drift.
• Material comparisons: If alternate steels are offered for different die environments, selection typically trades wear resistance for shock/toughness, but those specific options are not provided here.

For exact HRC and heat treatment state, confirm the base material grade for series 250301835266 before final die design sign-off.

Select dimensions by matching the punch geometry to the die’s mating bushing/hole and the receiver feature on your locating system. This series uses a fixed overall L = 80–130 mm, while several critical dimensions are variable to adapt to different die layouts.

• Shank diameter (D): Choose D = 10, 13, 16, 20, or 25 mm to fit the corresponding center-locator bore with appropriate clearance.
• Point length (L1): Match the available receiver engagement length: L1 = 13–19 mm or 19–25 mm.
• Tip shape: Select the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) that corresponds to the die feature geometry to avoid stress concentration and ensure repeatable locating.
• Geometric details: Verify P = 1.5–18 mm and W = 1.5–6 mm, and confirm the applicable R range (e.g., R = 0.2–5 up to 0.2–12.5 mm depending on variant).

Because XVP coating thickness and mating tolerances affect contact behavior, validate clearance and engagement depth during dry-fit; maintain consistent seating so the center line repeats under load.
