摘　　要：采用不同的锻压工艺制备了30CrMnSi钢机械筒座毛坯试样,并进行了冲击和磨损试验。结果表明:在试验条件下,随模具预热温度从150℃增加至350℃、始锻温度从1200℃增加至1275℃或终锻温度从780℃增加至840℃,筒座毛坯的冲击性能和耐磨损性能均先提高后下降。30CrMnSi钢机械筒座毛坯的模具预热温度优选为250℃、始锻温度优选为1250℃、终锻温度优选为820℃。30CrMnSi steel mechanical cylinder seat blank specimen was prepared by different forging processes, and impact and wear tests were carried out. The results show that under test conditions, the impact properties and wear resistance of cylinder steel increase firstly and then decrease with the die pre-heating temperature increasing from 150 ℃ to 350 ℃, the initial forging temperature increasing from 1200 ℃ to 1275 ℃ or the finish forging temperature increasing from 780 ℃ to 840 ℃. The optimized die pre-heating temperature, the initial forging temperature and the finish forging temperature of 30CrMnSi steel mechanical cylinder seat are 250, 1170 and 860 ℃, respectively.
