机械手(见图)是用来将大型圆柱形毛坯送到压力机的锻模上并将其置于预锻模槽内端部,随后将被锻毛坯移至最终锻模槽。机械手是由受料槽、毛坯夹钳、制动装置、毛坯沿锻模槽移动工具及联锁装置组成。毛坯夹钳固定在用压气气缸驱动的转动槓杆上。制动装置能保证将毛坯压紧在钳子中,联锁装置能保证模锻时钳子不致落在锻模下面。 The manipulator (see picture) is used to feed a large cylindrical blank to the press forging and to place it in the inner end of the preform, then to move the forged blank to the final forging slot. The manipulator is composed of the material receiving trough, the blank clamp, the brake device and the blank moving tool and the interlocking device along the forging die slot. The blank clamp is fixed on a rotary lever driven by a pneumatic cylinder. The brake ensures that the blank is pressed into the pliers and the interlock ensures that the pliers do not fall below the forging die during swaging.
