[0033] In operation, firstly, the pressing blocks 13 are continuously put into the sleeve 14 to stack, and the number of the pressing blocks 13 in the sleeve 14 is maintained. Under the action of gravity, the pressing blocks 13 in the sleeve 14 move downwards, and the lowermost pressing block 13 moves to the upper end of the sliding block 22. Then, the air cylinder 25 is started, and the push rod 24 is pushed to the left by the air cylinder 25, so that the push rod 24 drives the arc-shaped block 26 to extrude the pressing block 13 to the left. The pressing block 13 extrudes the limiting rod 32 to the left, and then the limiting rod 32 drives the sliding block 22, the pressing plate 31 on the sliding block 22 and the push block 42 to slide to the left. Further, the pressing block 13 moves to the lower end of the positioning rod 33, so that the upper end face of the pressing block 13 is limited by the positioning rod 33. With the movement of the sliding block 22 to the lower part of the punching device 12, the push block 42 moves to the sliding block 22 under the influence of the track of the guide rail 43, and then the push block 42 extrudes the pressing plate 31 to the side wall of the pressing block 13 through the elastic expansion rod 41, so that the position of the pressing block 13 is limited by the pressing plate 31.

Then, when the pressing block 13 moves to the punching device 12, the punching device 12 punches the pressing block 13 (at this time, the position of the pressing block 13 is limited in the front-rear direction by the pressing plate 31, in the left-right direction by the limiting rod 32 and the arc-shaped block 26, and in the up-down direction by the positioning rod 33 and the sliding block 22). Then, after the punching is completed, the push rod 24 continues to push the sliding block 22 to the left, so that the sliding block 22 moves to the discharging device 15 with the punched pressing block 13 (in this process, the pressing plate 31 gradually moves away from the sliding block 22). The discharging device 15 takes out the pressing block 13 from the equipment. Finally, the push rod 24 is reset by the air cylinder 25, and the sliding block 22 is reset under the action of the elastic force. It should be noted that in the process of pushing the push rod 24 to the left, the second pressing block 13 from bottom to top is extruded upwards, so that the pressing block 13 in the sleeve 14 is uniformly moved upwards. When the push rod 24 moves to the right and is reset, the pressing block 13 moves downwards under the action of gravity, so that the pressing block 13 in the sleeve 14 will be vertically up and down in the process of machining one pressing block 13, and then the vertical arrangement of the pressing block 13 in the sleeve 14 is ensured.
