Application scenario: Fully automated production line for gasoline engine pistons

 

Product Introduction:
This production line is mainly used to complete the entire processing content of Φ70~100mm ring-embedded aluminum alloy pistons (after casting heat treatment, external circle and top surface rough turning) from the start to the completion of fine machining. The entire production line's processing equipment consists of Taiwan's Fuyu vertical lathes, Mazak vertical machining centers, a set of numerical control combination boring machines, a set of special-shaped outer circle vertical lathes, and a special-shaped pin hole boring machine. Parts are transferred using a combination of articulated robots and ring-shaped material channels, achieving high flexibility and high automation of the production line. The overall technical indicators of the production line have reached the international advanced level, and the finished pistons meet the emission standards of Euro 5, Euro 6, or China 5, China 6 of OEM manufacturers.

Production Line Technical Description: Mainly composed of 7 numerical control piston outer circle vertical lathes, 6 vertical machining centers, 2 numerical control piston special-shaped outer circle vertical lathes (using a set of linear servo tool post systems), 1 numerical control piston combination boring machine, and 1 numerical control piston special-shaped pin hole boring machine, etc. Workpiece transfer is accomplished using 12 FANUC articulated robots and a set of transfer material channels to complete automatic loading and unloading, realizing unmanned automatic processing. It mainly completes the rough and fine machining processes of the piston's outer circle, ring groove, combustion chamber, pin hole, and valve recess.
     
The production line has a total length of approximately 32.5 meters, a total width of approximately 7.0 meters, and a total height of approximately 3.5 meters. The production line uses Mitsubishi multi-channel bus control. A typical workpiece piston weighs approximately 1 kilogram, and the processing cycle is approximately 15 seconds.
