Key process points:
1: Robot welding workshop: effectively control the impeller welding quality and balance, and the blade indexing accuracy reaches 0.01 mm
2: Subway hub boring and machining center: complete the machining of integrated blade mounting hole by clamping at one time, and the consistency error reaches 0.01 mm
3. Implement the molding process: the product structure has been adjusted, and the qualification rate is more than 98%.
4. Multi-station punch: implement the dual effects of mass production and new product development, and greatly improve the product standardization.
5: CNC plasma cutting: material cutting standardization, mass production.
6. Impeller dynamic balance: the unbalance of the impeller is far higher than the national standard.
7: CNC 5m vertical lathe: the fan diameter can be processed to more than 4m
8. CNC flanging and cutting equipment: high-precision blanking to ensure high-quality products.
9. Radiographic inspection equipment: conduct all-round internal organization inspection on die-cast blades to ensure that the impeller of metro fan is 100% qualified.
10. CNC rounding equipment: ensure that the roundness error of the winding is within 1.5mm, and improve the efficiency of the air duct forming and processing.
11: The air valve, cabinet machine, movement core and air duct are processed using the equipment integrated assembly line production mode, which is conducive to mass production and standard operation.
12: Water curtain painting room: dust-free painting to ensure appearance quality.
