目前各个主机厂开发出的流水槽造型在功能和用途上基本相同，只是形状和尺寸有所区别，根据AUTOFROM成形分析、工艺方案规划、模具结构设计、加工和钳工调试以及开发成本方面综合考虑，总结出以下4种针对流水槽的成形方案，分别为：流水槽下整形、流水槽斜楔侧翻、流水槽斜楔上翻与整形、流水槽下压料器上翻与整形。
At present, the function and use of the flow channel developed by each main engine factory are basically the same, but the shape and size are different. According to the autofrom forming analysis, process planning, die structure design, processing and fitter debugging and development cost, the following four forming schemes for the flow channel are summarized, which are: shaping under the water channel and slanting the flow channel It includes the following parts: wedge overturning, chute wedge turning up and shaping, downflow chute pressing device turning up and shaping.
