在锤锻模上应用导轨是为了防止模子在分模上发生错移。由于锻件形状不同及形成错移力的大小不同,导轨的种类也很多。一般常用的有圆导轨、长导轨和十字导轨等等。照例,一般的导轨的凹槽部分作在下模上,而凸起部分作在上模上,它们之间有很小的间隙。在模锻时,上模凸起部插进下模凹槽中。这种结构导轨有很大的缺 The use of guide rails on hammers is intended to prevent the mold from shifting on parting. Due to different forgings and the formation of different sizes of misalignment, rail types are also many. Commonly used round rail, long rail and cross rail and so on. As usual, the groove portion of a typical guide rail is made on the lower die, and the raised portion is made on the upper die with a small gap between them. In forging, the punch protruding portion into the mold cavity. This structure has a large lack of rails
