[0020] As Figure 1 - Figure 2As shown in the figure, a knife die changing auxiliary device for a cutting machine includes an operating table 1 and a fixing frame 2 fixedly connected to the upper surface of the operating table 1. A hydraulic telescopic rod 3 is installed from the middle position of the upper surface of the fixing frame 2 to the middle position of the lower surface. The lower end of the hydraulic telescopic rod 3 is installed with an upper cutting knife 4. The middle position of the upper surface of the operating table 1 is installed with a lower cutting knife 5. Auxiliary mechanisms 6 are provided on both sides of the front surface of the fixing frame 2. The auxiliary mechanism 6 includes a mounting frame 61 fixedly connected to the front surface of the fixing frame 2 by bolts. The inner surface of the mounting frame 61 extends to the outside and is threadedly connected with a threaded rod 62. The rear end of the threaded rod 62 is rotatably connected with a fitting block 63. A fixing mechanism 64 is provided on the rear surface of the fitting block 63. The outer surface of the mounting frame 61 is provided with scale lines to facilitate grasping the sliding positions on both sides. The fixing mechanism 64 includes a fixing seat 641 fixedly connected to the rear surface of the fitting block 63. The inside of the fixing seat 641 extends to the outside and is threadedly connected with a locking screw 642.

[0021] By adopting the above technical solution, during the cutting operation, the hydraulic telescopic rod 3 can drive the upper cutting knife 4 to approach the lower cutting knife 5 for cutting operation. When replacing the upper cutting knife 4, the old upper cutting knife 4 can be removed, and the new upper cutting knife 4 can be placed inside the fixing seat 641. Rotate the locking screw 642 to make the fastening block 643 fit the new upper cutting knife 4 to fix it. Rotate the two threaded rods 62 to make the fitting block 63 slide close to the upper cutting knife 4 to the same position.
