Then, the movable barrel 16 to be used can be selected by starting the second electric push rod 7. After selection, start the third electric push rod 21 to make the output end of the third electric push rod 21 descend. At this time, the movable barrel 16 that does not contact the output end of the second electric push rod 7 will slowly slide down together with the lower punching plate 19 under the action of gravity. It is necessary to select a suitable lower punching block. At this time, the sliding height is the height where metal powder can be stored. Select a suitable height and fill it with metal powder. Then start the first electric push rod 10, and the first electric push rod 10 will drive the upper punching block to press down. After the pressing is completed, start the first electric push rod 10 to make the upper punching block move upward and completely leave the workbench, so that the pressed metal block can be taken out.
