2. 14. 2 80MN水压机下料机械手液压系统设计
2. 14. Design of hydraulic system of 2 80MN hydraulic Press blanking manipulator
(1) 设计要求?
(1) Design requirements?
①设备工况及要求如下。
The working conditions and requirements of the equipment are as follows.
水压机下料机械手服务于80MN水压机，它的任务是将已压制成型的重型热工件取出，放到规定的上。该设备为直角坐标式机械手，它位于水压机的一侧，环境较为恶劣，温度较高，灰尘较多。
The cutting manipulator of hydraulic press serves the 80MN hydraulic press. Its task is to remove the heavy hot workpiece which has been pressed and put it on the prescribed. The equipment is a right-angle coordinate manipulator, which is located on one side of the hydraulic press, the environment is relatively bad, the temperature is high, and the dust is more.
②设备工作程序如下。
(2) the working procedures of the equipment are as follows.
启动机械手(该设备像小车，以下简称小车)沿轨道前进到水压机侧的工作位置，液压定位缸定位当工件成型后发出信号，小车的级和二级移动缸前进(即机械手伸进水压机内),此时手张开，到预后，升降缸下降(手下降)，到位后，夹紧缸工作，夹紧工件(手夹紧)，然后升起(升降缸工作)，到预后，一、二级移动缸返回(手退回)到预定位置，升降缸下降(手下降)，到预定位置，夹紧缸松开，把在小车的回转台上后再升起(手上升)，而后回转缸工作，把工件送到预定的工作线上由吊车取走。
The starting manipulator (the equipment is like a trolley, hereinafter referred to as the trolley) advances along the track to the working position of the hydraulic machine side, and the hydraulic positioning cylinder is positioned to send out a signal after the workpiece is formed. The primary and secondary moving cylinders of the car move forward (that is, the manipulator extends into the hydraulic press). At this time, the hand is open, and to the prognosis, the lifting cylinder drops (the hand drops), and when the cylinder is in place, the cylinder is clamped to work and the workpiece is clamped (hand clamped). Then rise (lift cylinder work), to prognosis, first and second level moving cylinder return (hand back) to predetermined position, lift cylinder drop (hand drop), to predetermined position, clamping cylinder loosening, Lift (hand up) on the turntable of the car, then turn the cylinder to work, send the workpiece to the predetermined working line and take it away by the crane.
