【摘要】 锻造前下料质量的优劣是直接关系到锻件质量的首道工序,也是精密模锻成形的必要条件。棒料剪切质量往往是制约精密模锻成形的关键因素。本文介绍了一种在通用型曲柄压力机上使用的带有自动压料和自导向装置的棒料精密剪切模的设计,其结构紧凑,适应性强,能较好地克服普通棒料剪切模常见的缺陷和弊端。更多还原

【Abstract】 The blocking quality before forging is the first and key process, and also the required step of fine module forging. It is often one of the key factors to induce the whole forging quality. In this article , it introduces a kind of fine shearing module with auto pressing unit and auto guiding unit used by general crank presses. It has a good availablity and this constructure can overcome the defects of ordinary bar shearing moudle.更多还原
