壳体锻件的精密模锻

Precision forging of casing part

为了提高壳体锻件的尺寸精度和表面质量,本文采用在曲柄压力机上安装吻合板的方法,固定曲柄压力机的下死点,将锻件的厚度尺寸公差控制在0.2mm以内,运用涂覆不锈钢玻璃润滑剂的方法,锻件表面仅有不到0.02mm的轻微氧化层。最终曲柄压力机上成形的壳体精密模锻件在尺寸精度、表面质量和机械性能上均优于指标要求。

In order to improve the dimensional accuracy and surface quality of the casing part, by installing fit-sheet on the crank press, the bottom dead center was fixed and the part thickness deviation was controlled within 0. 2 mm. Using one kind of glass-protective lubricant for stainless steel, the oxide layer Of forged part was less than 0. 02 ram. The properties of the precision forging part, such as dimensional accuracy, surface quality and mechanical property were superior to the targeted values.
