摘要:

为解决长枝杈喷油器体毛坯锻造时枝杈难以充满的问题,提出了一种局部镦粗—限流预锻—终锻—红切边成形工艺。采用结构分析的方法确定了原始坯料的尺寸为直径Φ32 mm、长度161 mm,并采用有限元和实验方法分析了该工艺的可行性。研究结果表明,新工艺预锻时限流槽能控制坯料流动,相比于常规成形方式,可在不增加坯料尺寸的情况下,将更多的金属聚集在锻件枝杈型腔处,并保证了终锻时长枝杈的充填完整,成功锻造出外形实完好的产品。

In order to solve the unfilled branch in forging process of fuel injector bodies with a long branch, a technology of local bulgingpreforging with controlled flowfinal forginghot trimming was put forward. Initial blank size with Φ32 mm in diameter and 161 in length was determined by the structure analysis method, and the feasibility of the forming technology was tested by FEM and experiments. The results show that the metal flow is controlled by the flow control slot in the preforging of the new technology. Comparing with normal forming, more metal materials are gathered into the branch cavity without increasing the billet size,and the long branch is filled completely in the final forging process. Thus, the wellshaped products can be forged successfully.
