Design of Manufacture Process Technology and Machine
Tongs for HangFa-X6130 Piston
 
Abstract : In the paper of this graduation design ,through the comprehensive explication of the developing of aluminum piston of the internal-combustion engine whose the machining technologies,the surrounding of working and the analysis of structural of the piston.It is conformed the technology process and arrange for process of HF-X6130 piston. It mainly includes:produce outline and produce type to be conformed,choose material,the manufacturing method of the semi-finished product of material,the amount of remaining of machine process to be conformed ,the cutting dosage of each process to be conformed,calculated the working procedure time and draw up the working procedure.Lastly,chose and designed two sets of typical model of tool machine tongs,designed the tongs of drilling the oil bore and designed the tongs of the milling machine.It mainly includes among them:the position project and the pressure designed,the cet degree design,two sets of wrok principles of tongses and what we must be notice in the process of the piston design.Through the analysis and argument,the arts and crafts design and the tongs design of the HF-X6130 piston is viable.
