在各机械制造部门的锻造生产中,对轴对称零件,其中包括环的多工位无毛边模锻,均使用热顶锻自动机。在轴承工业中,这些自动机正在《重型锻压机械》联合生产公司研制的Л—309自动线中成功地工作。Л—309自动线由棒料机械化架,感应加热装置,压力为12.5MH的四工位热顶锻自动机,卸载环和废料运输机组成。在自动线上,模锻直径小于120MM,重量3K Γ以下的台阶式制件采用成套锻造法。即把直径尺寸不同的两个彼此内切的环形工件用筋连接在一起锻
In the forging production of various machinery manufacturing sectors, hot forging robots are used for axisymmetric parts, including multi-station blankless forging of rings. In the bearing industry, these robots are working successfully in the Л-309 automatic line developed by the Heavy Forging Machinery joint production company. Л-309 automatic line by the bar mechanized frame, induction heating device, the pressure of 12.5MH four-position hot forging machine, unloading ring and waste transport aircraft. On the automatic line, die forging diameter of less than 120MM, weighing 3K Γ below the step-type parts using a set of forging method. Namely the diameter of the two different sizes of the inner annular workpiece connected together forging
