厚实床身的铸造工艺

Casting Technology of Solid Pressing Machine Frame

床身是锻压机床上的重要零件,系大断面厚实铸件。因铸件较厚实,生产中易产生缩孔、缩松等缺陷。通过拼箱组芯造型、利用浇注系统补缩、采取低温慢浇和充分补浇等工艺措施,保证了床身铸件质量。

One of the important components of forging pressing machine is its frame which is a solid casting with large section that is apt to defects such as contraction cavity and dispersed shrinkage which can be avoided by technological measures such as grouping the cores in joggle joint molding and proper gating system and slow pouring low temperature melt and adequate compensating pouring to guarantee quality of castings.
