Abstract:

  The mechanical equipment and forging principle of precision forging press were introduced, and the cooperation process between the key actions of precision forging press-eccentric forging of hammer head, intermittent rotation of chuck and manipulator follow-up feeding was discussed in detail, the displacement curve for eccentric movement of hammer head was deduced, and the forging period and forging interval period of hammer head were divided reasonably. Then, according to the forging error, the limit rotation speed of chuck was calculated, and combined with the cooperation mechanism of hammer head forging and chuck rotation, the chunk intermittent rotation method for servo cylinder speed compensation was proposed, and the expected running track of compensation cylinder suitable for the forging cycle of precision forging press was analyzed. Furthermore, for the deformation and elongation problem of forgings in precision forging press, an engineering actualized manipulator follow-up feeding method was proposed, and based on spiral forging process with four hammer heads, the optimal feeding speed of two-side manipulators was proposed, which could make the circumference of workpiece evenly forged by hammer head. Finally, the research ideas of cooperative control of the key actions for precision forging press were summarized, which could be the foundation of the subsequent development and domestic application.
