Precision Die Design and Material Handling Improve Quality Control while Exceeding Production Requirements
This system required the ability for 2 different size rotor shafts to be fed by an indexing conveyor into a Stamtec 80 ton gap press. Our customer needed to ensure that the material handling system would not damage or mark the shafts. Additionally, the machine vibration due to press size would not be an issue to other precision machinery in the production line.
Aladdin Engineering and Manufacturing designed the entire system to run at rate and be fully automatic. Rotor shafts are fed via an indexing conveyor onto a Stelron walking beam that presents the shaft centerline horizontal in the press. Once in the die, the crowding cylinder pushes the shaft to a repeatable location. The spline is then automatically coined and unloaded onto an exit conveyor. Tooling currently allows for 2 different size shafts with a manual changeover and is designed to be modified for other size shafts in the future. The press produces 1,090 shafts per hour, which exceeds the customer’s required production rate by 10%. A special design of the isolation pads eliminated vibration worries along with the need for additional stabilizing components and a dedicated concrete foundation.
