The TRUMPF Style Emboss Tooling is a specialized, matched pair of upper and lower dies designed to execute a localized, non-cutting deformation of the sheet metal, forcing a section of the material to project above the plane of the sheet.
Feature:
Positive Displacement Pair: This tool is defined by its two co-acting components: the punch assembly (or Form Holder) and the lower Die assembly (or Matrix). The Male element possesses the convex geometry of the desired feature, while the Female element holds the corresponding concave cavity.
Non-Cutting Flow: Unlike standard punching that utilizes shearing forces, this tooling mandates a controlled, plastic flow of the material. The punch descends, pressing the metal into the precise negative cavity of the die, causing the material to stretch and migrate into the prescribed three-dimensional shape.
Controlled Radii: The forming surfaces are machined with meticulous radii and draft angles to manage the internal stresses on the sheet. This is critical to prevent the material from fracturing or tearing at the point of greatest elongation, ensuring the integrity of the finished embossment.
Stripping via Ejector: The die typically incorporates a spring-loaded ejector pad or a stripper retainer. Following the forming stroke, this pad positively rejects the now-shaped material from the female die cavity, preventing the sheet from clinging due to the pressure-induced deformation and facilitating its smooth onward transit.
Application:
The emboss tooling is deployed when the requirement is to create functional or aesthetic features that project away from the machine's bolster plate and stand proud of the material's top surface.
Stiffening Features: It is universally used to create beads, ribs, or domes that act as localized stiffeners, structurally reinforcing broad, flat panels to mitigate unwanted flexure or vibration (oil canning).
Location and Mating: It forms precision dimples or raised bosses that serve as positive stops, pilasters, or locators for mounting components, ensuring accurate alignment with mating parts (e.g., creating a fixed point for a self-tapping screw or aligning a printed circuit board).
Cosmetic Accentuation: It is utilized for aesthetic branding or for creating tactile indicator bumps (like Braille), providing visual or sensory texture without piercing the material's fluid barrier.
