1、 1 热加工工艺课程设计说明书 课程: 热加工工艺课程设计 题目: 轴承座铸造工艺设计 姓名: 专业: 机械设计制造及其自动化 班级: 机电一班 学号: 指导老师: 课程完成时间:2012/5/18 至 2012/5/31 2 摘要 在机械制造过程中,由于加工过程十分复杂,加工工序繁多,工 艺过程不仅有金属铸造成形,锻压成形,焊接成形,还有非金属的模 压成形,挤压成形和滚压成形等。 铸造是将液态金属或合金浇注到与零件尺寸, 形状相适应的铸型 型腔中, 待冷却凝固后获得毛坯或零件的方法,是机械零件和毛坯成 型的主要方法, 尤其适合制造内腔和外形复杂的毛坯或零件,俗称为 铸件。 通常按照其铸型性质
2、不同,可分为砂型铸造,特种铸造和快速铸 造。 Summary In mechanical manufacturing process, because processing process is very complex, processing operations is various, the process has not only forming metal casting, forging press forming and welding forming, and the moulding nonmetal forming, extrusion forming and rollin
3、g forming, etc. The casting is will the liquid metal or alloy casting to and parts size, shape adaptation of the mould cavity, wait for after cooling solidification get blank or parts of the method, is the mechanical parts and blank forming of the main methods, especially suitable for manufacturing
4、the inner cavity and appearance of the complex blank or parts, better known as casting. Usually according to the different properties casting, sand casting can be divided into, special casting and fast casting. 3 目录 摘要2 1. 零件结构工艺分析4 2. 铸造工艺方案拟定5 (1) 铸型及方法选择5 (2) 分型面选择5 (3) 浇注位置确定6 3. 铸造工艺参数确定6 (1) 切削加工余量6 (2) 铸件收缩率
