[0023] According to the present specific embodiment, the pushing mechanism 105 is fixedly connected to the hydraulic press 103, the hydraulic press 103 is fixedly connected to the base 101, the pressure plate 102 is fixedly connected to the base 101, each of the abutting needles 108 is fixedly connected to the abutting plate 107, the two pneumatic rods 106 are fixedly connected to the abutting plate 107, the abutting plate 107 is movably connected to the base 101, the two support blocks 111 are respectively fixedly connected to the corresponding first hydraulic rods 110, the two first hydraulic rods 110 are fixedly connected to the bottom plate 109, the pressed cake 115 is fixedly connected to the pressing machine 114, the two second hydraulic rods 113 are movably connected to the pressing machine 114, one end of the two second hydraulic rods 113 is movably connected to the machine body 112, and the two second hydraulic The other ends of the rods 113 are fixedly connected to the corresponding supporting blocks 111, the pushing blocks 119 are movably connected to the two connecting rods 118, the other ends of the two connecting rods 118 are movably connected to the movable rod 116, the rod shaft 117 is fixedly connected to the movable rod 116, and the rod shaft 117 is movably connected to the machine body 112. Through the provided abutment plate 107 and a plurality of abutment needles 108, after the tungsten rod on the hydraulic press 103 is squeezed with the pressure plate 102, the abutment plate 107 moves upward under the action of the pneumatic rod 106, just abutting the top end of the abutment needle 108 with the horizontal plane of the pressure plate 102, thereby avoiding the tungsten rod from remaining in the pressure plate 102. This design solves the problem in the prior art that part of the tungsten rod will remain in the pressure groove after being squeezed in the pressure groove, which is easy to cause blockage.
