抛丸工艺是一种利用丸料对材料表面的高速冲击进行表面处理的相关工艺。为使抛丸机的工作效率与工艺更加优化，本研究通过数学分析并经过实验机验证调整设计新型的抛丸机。对抛丸机关键零部件尺寸及位置进行优化设计与讨论，通过实验调整抛头、定向套的位置和角度使抛丸宽幅达到1 000 mm，同时保证最佳的抛丸效果。

Shot blasting process is a process which use of shot blasting material to effect high-speed impact on the surface of material to achieve the purpose of surface treatment. In order to make the working efficiency and process of shot blasting machine more optimization, this research through mathematical analysis and validation adjustment by experimental machine design new type of shot blasting machine. This research conduct optimize design and discussion for the size and position of key parts of shot blasting machine, adjust position and angle of throwing head and orientation sleeve by experiment to make the shot blasting width reach 1 000 mm, and at the same time ensure best shot blasting effect.
