Detailed ways

The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 3, the automatic clamping mechanism of the knife template of the cutting machine includes: a frame 1, a cutting cylinder 2 is arranged on the frame 1, and the piston of the cutting cylinder 2 The rod 3 is provided with a die holder 4, and a die clamping block 5 is arranged on the front and rear sides of the lower end of the die holder 4, and the two ends of the die clamping block 5 slide through the guide rod 6 respectively. Set on the die die holder 4, a die die 7 is slidably arranged in the die die clamping block 5, a die die 8 is arranged at the lower end of the die die die 7, and a die die 8 is arranged at the upper end of the die die holder 4 The front and rear sides are respectively provided with a die clamping block push-pull mechanism that cooperates with the die die clamping block 5, and the die die clamping block push-pull mechanism includes: two first sliding seats arranged on the die die fixing seat 4 9. A second sliding seat 10 is provided on the die fixing seat 4 on one side of the first sliding seat 9, and a sliding rod 11 is slidably arranged in the first sliding seat 9, and the sliding rod 11 extends The left end of the first sliding seat 9 is provided with a spring limiting block 12, and a return spring 13 is sleeved on the slide bar 11 between the spring limiting block 12 and the first sliding seat 9, and the return spring 13 One end abuts against the spring limiting block 12, the other end of the back-moving spring 13 abuts against the first slide seat 9, and an extruding cylinder 14 is arranged on the frame 1 at the left end of the spring limiting block 12. The piston rod 15 of the air cylinder 14 is provided with an extruding block 16 cooperating with the spring limit block 12, and a movable block 17 is respectively arranged in the two second sliding seats 10, and the left end of the movable block 17 is below the It is connected with the die clamping block 5, and the lower part of the movable block 17 is movably connected with the second sliding seat 10 through a hinge. In the movable block 17, a pin shaft chute 18 is obliquely arranged, and between the two Slider blocks 19 are slidably arranged in the slide block 10 respectively, and a pin shaft 20 cooperating with the pin shaft chute 18 is arranged on the slider block 1, and the two slider blocks 19 are connected by a connecting rod 21. A chuck 22 is arranged in the middle of the connecting rod 21 , and a locking block 23 cooperating with the chuck 22 is arranged on the sliding rod 11 .

When the automatic clamping mechanism of the knife template of the cutting machine is used, the extrusion cylinder 14 is started, the piston rod 15 of the extrusion cylinder 14 pushes the extrusion block 16 to move to the right, the extrusion block 16 pushes the spring limit block 12 to move to the right, and the spring The limit block 12 drives the slide bar 11 to slide to the right in the first slide seat 9, and the return spring 13 is squeezed. When the slide bar 11 moves to the right, the block 23 on the slide bar 11 drives the chuck 22 to move to the right, and the chuck 22 moves to the right.
