用于批量生产中小型板料冲压件的冷冲模中,有导向装置的特别是导板式与导柱式冲模使用越来越广,其主要零部件及各种典型设计组合都已纳入GB2851～2875—81《冷冲模》中.1990年该国标进行了修订,对其中模架、模座及其零部件等有关部分进行了增补和修改,并调整为推荐使用的国家标准,但主要内容未变动,尤其是典型组合部分仍存在许多问题和一些明显的错误,本文仅对GB2874.1～2874.2—81《冷冲模导板模典型组合纵向送料典型组合》与《冷冲模导板模典型组合横向送料典型组合》中存在的问题提出商榷意见和修订建议.
Used in mass production of small and medium-sized sheet metal stamping parts of the die, there are guides, especially guide plate and guide column die is more widely used, the main components and various typical design combinations have been included GB2851 ~ 2875 -81 “Die.” In 1990, the national standard was revised, in which the mold frame, mold base and its parts and other related parts were added and modified, and adjusted to the recommended national standards, but the main content did not change , Especially the typical part of the combination of many problems still exist and some obvious errors, this article only on GB2874.1 ~ 2874.2-81 “die-die combination of typical combination of longitudinal die-feeding typical combinations” and “die-die die-typical combination of horizontal feed typical combination ”Questions in the proposed discussion and suggestions for revisions.
