鍛工車間鍛造中小形鍛件,例如圆头銷子、螺栓、和閥类鍛件等,差不多都是用50～75公厘的圆料,下料长度按L≤1.5D計算,而且要求切割后的坯料断面不变,两端垂直;为了节省原材料,鍛件鍛完后杆端不切头,要求坯料的体积同鍛件的体积(包括燒损量)相等。一般沒有切料設备的工厂,使用机錘热切材料,要想满足这个要求是比較困难的。現在介紹的一种热切材料方法,不只在效率上要比
Forging workshop forging small and medium-sized forgings, such as round pegs, bolts, and valve forgings, etc., are almost all round with 50 to 75 mm material, blanking length calculated by L ≤ 1.5D, and requires cutting the blank Cross-section unchanged, both ends of the vertical; In order to save raw materials, after forging rod ends do not cut head, requiring the volume of blank with forging volume (including the amount of burning) equal. In general, there is no cutting equipment factory, the use of machine hammer eager material, to meet this requirement is more difficult. An eager material approach now introduced is not only more efficient
