[0027] Working principle: A counterweight pressing device. When producing dumbbell counterweights, first put the prepared cement and sand mixture into the storage box 13, start the hydraulic cylinder 3 to contract, and bring the lifting plate 4 and the punching block 5 up. Through the pulling of the connecting rod 14, the sliding frame 12 and the storage box 13 are moved closer to the front end. When the lifting plate 4 rises to the highest point, the bottom of the discharge pipe 15 just reaches the punching hole 901. At this time, the control valve 16 is opened, so that the raw material falls into the punching hole 901, and the lifting plate 4 is started to extend, so that the punching block 5 moves downward. At the same time, the sliding frame 12 and the storage box 13 move backward. Under the action of the cylindrical protrusion and the special-shaped hole 21, the T-bar 18 brings The two scraper rods 19 swing back and forth, so that the scraper rods 19 flatten the raw material, which is convenient for pressing the punching block 5. When the cylindrical protrusion slides to the straight hole at the rear end of the special-shaped hole 21, the scraper rod 19 will not move and will not affect the pressing of the punching block 5. A hole compatible with the insertion rod is opened in the middle position of the bottom of the punching block 5. Through the cooperation of the punching block 5, the punching hole 901 and the cylindrical base 10, the raw material is turned into a solid counterweight block, and then the hydraulic cylinder 3 contracts to make the punching block 5 rise, and the storage box 13 moves forward again, and then the electric push rod 8 is started to extend, so that the lifting platform 9 descends. At this time, the user can easily take out the pressed counterweight block, and then the lifting platform 9 is reset to press the next counterweight block.
