A top plate 1.8 is fixed between the tops of the guide rods 1.5; specifically, the top of the guide rods 1.5 is threaded; through holes are opened at both ends of the top plate 1.8 corresponding to the positions of the guide rods 1.5; the top plate 1.8 is sleeved on the guide rods 1.5 through the through holes; nuts are installed at the threaded positions on the upper and lower sides corresponding to the through holes of the top plate 1.8.

The drive shafts of each group of shaping mechanisms 1 are connected in series through parallel eccentric couplings 5. The parallel eccentric coupling 5 is a specially designed coupling, mainly used to connect transmission shafts with axial deviation or eccentricity. Its core function is to maintain the stability of power transmission while allowing a certain amount of eccentricity.

Unless otherwise described, the fixing methods described above all use welding or threaded fastening techniques commonly used by industry professionals.

[0020] The working principle is as follows: Solid sodium metal rods are fed into the forming mechanism 1 from the inlet. As the rods are shaped, the roller belt 1.3 rotates, moving the rods to the outlet end of the forming mechanism 1. After exiting the outlet, the solid sodium metal rods enter the base plate 221 within the support 2.2. During this movement, the roller belt 1.3 moves the rods along the slide rail, while the spring 2.4 is stretched. The cutting hydraulic cylinder 2.5 performs the cutting operation. During cutting, the roller belt 1.3 continues to convey the rods, but its speed should not be too fast; the cutting speed must be sufficient to ensure that the support 2.2 completes the cutting operation before the slide rail reaches its maximum stroke. The cut solid sodium metal rods are transferred to the next process section via the conveyor roller 4, while the support 2.2 returns to its initial position under the action of the spring 2.4.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
