[0028] The top of the mounting frame 10 is integrally connected with the operating table 1. Figure 1 As shown, an open slot is provided on the operating table 1, and a first feeding roller 21 is provided in the open slot. The shape of the feeding roller is as follows: Figure 1 As shown, the bar material can be located in the groove on the feed roller for movement, and both ends of the first feed roller 21 are rotatably connected to the mounting frame 10, and the mounting frame 10 is connected to the second feed roller 4 through the lifting assembly. By arranging the first feed roller 21, the second feed roller 4 and the lifting assembly, etc., the bar materials with different diameters within a certain range can be electrically fed;

[0029] The mounting frame 10 is symmetrically mounted with fixing plates 13, a cutting mechanism 8 is mounted on the top of one fixing plate 13, a cutting groove 22 is provided directly below the cutting mechanism 8, a limiting strip 20 is integrally formed and connected to one side of the mounting frame 10, a moving frame 15 is slidably connected to the limiting strip 20 and the mounting frame 10, a limiting frame 11 is welded and fixed inside the moving frame 15, a pressure sensor 12 is mounted on the limiting frame 11, a distance sensor 14 is mounted at a position corresponding to the limiting frame 11 and the fixing plate 13, a first motor 16 is mounted on one side of the moving frame 15, a gear 17 is mounted on the output shaft of the first motor 16 through a coupling, and the mounting frame 10 is provided with a plurality of movable frames 15, wherein the movable frame 15 ... A tooth plate 9 is welded on one side, and the tooth plate 9 is meshed with the gear 17. Under the joint action of the fixed plate 13, the distance sensor 14, the pressure sensor 12, the limit frame 11, the first motor 16, the gear 17 and the tooth plate 9, the limit plate 7 can be moved to the required length position. When one end of the rod is against one side of the limit plate 7 and the value measured by the pressure sensor 12 reaches the preset value, the controller 18 controls the first motor 16 to stop working, and the electric push rod 6 brings the limit plate 7 to limit the rod, and then the cutting mechanism 8 cuts it. The whole process does not require manual movement and measurement, and is more convenient to use.
