[0030] The following combines the attached Figure 1 —4 to make a further detailed description of this application.
[0031] The embodiment of this application discloses a double-hopper structure for sintered particle pressing and forming. Refer to Figure 2 - Figure 4, A double-hopper structure formed by sintered particle pressing, including a double-hopper main body 10. There are two hopper cavities 51 provided on the double-hopper main body 10. The inner walls of the hopper cavities 51 are provided with movable ports 52 that communicate with the two hopper cavities 51 respectively. The surface of the double-hopper main body 10 is provided with two moving ports 11 corresponding to communicate with the hopper cavities 51. A fixed block 53 is movably assembled on the movable port 52. Symmetrically fixed assemblies of connecting rods 71 are arranged on the symmetric two side surfaces of the fixed block 53. One ends of the two connecting rods 71 are fixedly assembled with a limiting block 60. Movable blocks 61 are movably assembled on the two connecting rods 71. Support rods 62 are fixedly assembled on the surfaces of the movable blocks 61. An operating rod 72 is fixedly assembled on the fixed block 53. A rhombic block 73 is movably assembled on the operating rod 72. Fixed rods 80 are symmetrically fixedly assembled on the rhombic block 73. Near the two ends of the fixed rods 80 close to the rhombic block 73, assembly rods 81 are fixedly assembled on the movable blocks 61. Guide blocks 82 are movably assembled on the assembly rods 81. The other ends of the guide blocks 82 are movably assembled with the fixed rods 80 correspondingly. A cylinder 83 is fixedly assembled at the bottom of one of the movable blocks 61. The output end of the cylinder 83 is fixedly assembled with a piston rod 90. One end of the piston rod 90 is fixedly assembled with the fixed block 53. Filler blocks 12 are fixedly assembled on the inner walls of the hopper cavities 51. A plurality of filler holes 13 are penetrated through the filler blocks 12. Lower connecting plates 63 are fixedly assembled on the tops of the support rods 62. The lower connecting plates 63 are located below the filler blocks 12. Pressing blocks 70 are fixedly assembled on the lower connecting plates 63. The pressing blocks 70 move correspondingly on the filler holes 13. After the sintered particles are pressed and formed in the filler holes 13 of the filler blocks 12, the fixed block 53 moves downward in the movable port 52, so that the lower connecting plate 63 drives the pressing block 70 away from the filler holes 13 on the filler blocks 12. Under the action of gravity, the formed sintered particles are on the pressing block 70 and the lower connecting plate 63. Start the cylinder 83. Under the thrust of the piston rod 90, one of the movable blocks 61 moves on the connecting rod 71. Under the coordinated action of the guide block 82 and the rhombic block 73, the moving directions of the two movable blocks 61 on the connecting rod 71 are opposite, which is convenient for the pressing block 70 on the lower connecting plate 63 to move reciprocally in the hopper cavity 51, facilitating the throwing out of the formed sintered particles on the lower connecting plate 63 and the pressing block 70, and facilitating the formed sintered particles to fall out from the double-hopper main body 10.
[0032] Refer to Figure 1 - Figure 3, two sets of sliding grooves 20 are fixedly assembled on the double hopper body 10. The number of each set of sliding grooves 20 is two. Traction racks 21 are movably assembled on each of the two sliding grooves 20 in each set. One end of each traction rack 21 is fixedly assembled with a traction block 22. A regulating rod 23 is fixedly assembled on each traction block 22. One of the regulating rods 23 moves corresponding to the moving port 11, and one end of the regulating rod 23 is fixedly assembled with a limit block 60. One end of the other regulating rod 23 is fixedly assembled with an upper connecting plate 41. The upper connecting plate 41 is located above the packing block 12. A upper pressing block 42 is fixedly assembled at the bottom of the upper connecting plate 41. The upper pressing block 42 moves corresponding to the packing holes 13. An installation frame 30 is fixedly assembled on each set of sliding grooves 20. A rotating rod 31 is movably assembled on the installation frame 30. One end of each rotating rod 31 is fixedly assembled with a traction gear 32. The traction gears 32 are respectively engaged with the two traction racks 21 on both sides by tooth patterns. The other end of each rotating rod 31 is fixedly assembled with a sprocket 33. A chain 40 is wound around the two sprockets 33. A fixing frame 43 is fixedly assembled on one of the installation frames 30. An operating motor 50 is fixedly assembled on the fixing frame 43. The output end of the operating motor 50 movably penetrates through the fixing frame 43, and the output end of the operating motor 50 is fixedly assembled with one of the sprockets 33. When the lower pressing block 70 on the lower connecting plate 63 extends into the packing holes 13 of the packing block 12 and equal amounts of sintered particles are poured into the packing holes 13 of the packing block 12 respectively, start the operating motor 50. Driven by the chain 40, the two sprockets 33 rotate in the same direction. The sprockets 33 drive the traction gears 32 to rotate through the rotating rods 31. The traction gears 32 are respectively engaged with the two traction racks 21 by tooth patterns, so that the two traction racks 21 move in opposite directions on the sliding grooves 20 respectively. The upper pressing block 42 on the upper connecting plate 41 approaches the lower pressing block 70 on the lower connecting plate 63, and the sintered particles are pressed and formed in the packing holes 13 of the packing block 12.
[0033] Working principle: When the lower pressing block 70 on the lower connecting plate 63 extends into the packing hole 13 of the packing block 12, equal amounts of sintered particles are poured into the packing holes 13 on the packing block 12 respectively. The operating motor 50 is started. Driven by the chain 40, the two sprockets 33 rotate in the same direction. The sprocket 33 drives the traction gear 32 to rotate through the rotating rod 31. The traction gear 32 is engaged with the two traction racks 21 by tooth patterns respectively, so that the two traction racks 21 move in opposite directions on the sliding grooves 20 respectively. The upper pressing block 42 on the upper connecting plate 41 and the lower pressing block 70 on the lower connecting plate 63 approach each other, and in the packing hole 13 of the packing block 12, the sintered particles are pressed into shape. After the sintered particles are pressed into shape in the packing hole 13 of the packing block 12, the fixed block 53 moves downward in the movable opening 52, so that the lower connecting plate 63 drives the lower pressing block 70 away from the packing hole 13 of the packing block 12. Under the action of gravity, the formed sintered particles are on the lower pressing block 70 and the lower connecting plate 63. The air cylinder 83 is started. Under the thrust of the piston rod 90, one of the movable blocks 61 moves on the connecting rod 71. Under the coordinated action of the guiding block 82 and the diamond-shaped block 73, the two movable blocks 61 move in opposite directions along the moving direction of the connecting rod 71, which is convenient for the lower pressing block 70 on the lower connecting plate 63 to reciprocate in the hopper cavity 51, facilitating the throwing out of the formed sintered particles on the lower connecting plate 63 and the lower pressing block 70, and facilitating the formed sintered particles to fall out of the double-hopper main body 10.
