DIN 9845 Type B die bush

Precision in high-volume punching and blanking operations is non-negotiable. To achieve this, choosing the correct, standardized tooling components is fundamental. For applications demanding superior guidance and extended service life, the Die buttons DIN 9845 type B are engineered for excellence. This specific type, characterized by its press-fit design with a shoulder, offers a robust and secure mounting solution within the die plate. Its primary function is to provide an accurate and wear-resistant cutting edge for the punch, ensuring clean, burr-free parts and maintaining tight tolerances over millions of cycles. When paired with a precisely fitted punch, the DIN 9845 type B Drill Guide Bushing system guarantees minimal clearance and optimal alignment, directly contributing to reduced downtime, improved part quality, and overall tooling efficiency.
The <产品名字> is manufactured to the exacting specifications outlined in the DIN 9845 standard for Type B. This standardization ensures interchangeability, simplifies inventory management, and guarantees dimensional consistency across suppliers. These components are typically crafted from high-grade tool steels, such as 1.3343 (ASP 23) or 1.2379 (D2), which are then heat-treated to achieve a high surface hardness, often in the range of 60-62 HRC, for exceptional wear resistance. The internal bore, which serves as the cutting surface, is precision-ground to an exceptional finish (e.g., Ra ≤ 0.2 µm) to minimize friction and material adhesion. The external cylindrical surface is also ground to precise tolerances for a secure press-fit into the die plate. The shoulder provides a positive stop during installation, ensuring correct axial positioning and preventing the button from being pressed too deeply. Common sizes are readily available for various punch diameters, making them a versatile choice for countless stamping applications.
