[0008] 1. When the present utility model performs the hard pressing and forming operation of the electric bicycle bottom bracket, the feeding slider is moved to the extreme position on the side of the feeding groove far from the extrusion material entering the slideway. The raw material to be processed is placed inside the feeding groove. By starting the feeding hydraulic cylinder, the raw material to be processed is fed into the inside of the extrusion material entering the slideway. After the loading is completed, the extrusion hydraulic cylinder pressurizes the raw material to be processed. When the raw material passes through the inside of the hard pressing and forming die set, the hard pressing and forming is completed. The hard pressing is integrally formed, with fewer processing procedures, simple processing operations, smooth parts after processing, better aesthetics, and high machining accuracy of the parts.
