本文通过新型管材扒皮模设计与工艺实践,探讨了管材扒皮模的结构、拉伸工艺条件与拉伸扒皮环、扒皮撕裂的因果关系,设计了生产表面“零缺陷”管材的新型管材扒皮模。 In this paper, through the design and process practice of the new tube skinning model, this paper discusses the causal relationship between the structure of the skinning tube model, the stretching process conditions and the stretching and peeling of the skinning ring and the peeling of the peeling skin, and designs a new type of tube with “zero defect” Pa skin model.
