Spoke extrusion vent holes
Product Overview
This die is specifically designed for the efficient forming of cooling (ventilation) holes in steel wheel spokes—used in trucks, buses, and construction machinery. Its structure enables single‑stroke punching with indexing via a central rotary table, allowing for the production of varying hole counts. Additionally, by swapping out the corresponding punch and die sets for venting holes, any burrs generated during punching can be eliminated.
Key Features
High precision and low burrs
The clearance between the precision‑matched punch and die (optimized according to sheet thickness), combined with a back‑stop device, ensures that the burr height is controlled within… ≤0.1mm 。
Key words:
