[0018] The anti-drop device 6 includes a limit block 61, the inner wall of the limit block 61 is rotatably connected with a bidirectional screw 62, both ends of the bidirectional screw 62 are threadedly connected with an L-shaped plate 64, the inner wall of the L-shaped plate 64 is slidably connected with a positioning rod 63, the outer wall of the L-shaped plate 64 is rotatably connected with a fixing device 65, the outer wall of the fixing device 65 is slidably connected with a fixing frame 66 through a positioning groove 67, and the positioning groove 67 is provided in the wall of the fixing frame 66, the outer wall of the fixing frame 66 is fixedly connected with a triangular block 68, the two ends of the positioning rod 63 are fixedly connected to the inner wall of the limit block 61, the outer wall of the limit block 61 is fixedly connected to the inner wall of the positioning frame 4, the inner wall of the positioning frame 4 is slidably connected to the outer wall of the L-shaped plate 64, the inner wall of the positioning frame 4 is rotatably connected to the outer wall of the bidirectional screw 62, the inner side wall of the fixing frame 66 is fixedly connected to the side wall of the mold 5, and the staff fixes the fixing frame 66 and the mold 5 Put it into the punch head 2, and then cooperate with the clamping device 3 to fix the mold 5. When the mold 5 is fixed, rotate the bidirectional screw 62 to drive the fixing devices 65 to move closer to each other. During the movement, the hook 654 on the rotating rod 651 is blocked by the fixed frame 66. Due to the arc surface setting of the hook 654, the end of the hook 654 moves down, and the rotating telescopic rod 655 is stretched at the same time. After the hook 654 moves to the position of the positioning groove 67, the previously stretched rotating telescopic rod 655 shrinks, so that the hook 654 is in the positioning groove 67. When the clamping device 3 is released and the mold 5 falls with the fixed frame 66, the hook 654 hooks the positioning groove 67 of the fixed frame 66, and the rotating rod 651 stretches the rotating telescopic rod 655 while rotating until the blocking block 653 presses against the bottom of the L-shaped plate 64 to prevent the fixed frame 66 from falling further, thereby preventing the mold 5 from falling.

[0019] The fixing device 65 includes a rotating rod 651, and fixed blocks 652 are rotatably connected to both sides of the rotating rod 651, and a blocking block 653 is fixedly connected to the outer wall of the rotating rod 651, and a hook 654 is fixedly connected to the end of the rotating rod 651 away from the blocking block 653, and a rotating telescopic rod 655 is rotatably connected to the outer wall of the top of the rotating rod 651. The end of the rotating telescopic rod 655 away from the rotating rod 651 is rotatably connected to the outer wall of the L-shaped plate 64, and the bottom of the L-shaped plate 64 is fixedly connected to the top of the fixing block 652. When the hook 654 enters the positioning groove 67, the bidirectional screw 62 is rotated to drive the two L-shaped plates 64 away from each other. The pulling forces on both sides of the fixed frame 66 are opposite, so that the fixed frame 66 is subjected to opposite pulling forces at the same time, thereby tightening the fixed frame 66, so that the side walls inside the fixed frame 66 are prestressed to resist the thrust generated by the stamping of the mold 5, so that the fixed frame 66 has higher usage strength and delays the damage time of the fixed frame 66.

[0020] Working principle:

[0021] When in use, an anti-drop device 6 is provided to prevent the mold 5 from falling and damaging the punch press protective shell 1 after the punch head 2 removes the mold 5. Before installing the mold 5, the bidirectional screw 62 leaking out of the punch press protective shell 1 is rotated. Due to the opposite thread setting of the bidirectional screw 62, the two L-shaped plates 64 are simultaneously approached and moved away from each other under the rotation of the bidirectional screw 62. At this time, the two L-shaped plates 64 are driven to move in the positioning frame 4. Under the positioning action of the positioning rod 63 on the limit block 61, the two are moved away from each other. At this time, the fixing device 65 gives way, and the staff can put the fixing frame 66 and the mold 5 into the punch head 2, and then cooperate with the mold locker 3 to fix the mold 5. When the mold 5 is fixed, the bidirectional screw 62 is rotated to drive the fixing devices 65 to approach each other. Due to the setting of the rotating telescopic rod 655 on the fixing device 65, the rotating rod 651 pushes The upper plane remains parallel to the bottom plane of the fixed frame 66 without additional force. The moving L-shaped plate 64 drives the rotating rod 651 to move through the fixed block 652. During the movement, the hook 654 on the rotating rod 651 is blocked by the fixed frame 66. Due to the arc surface setting of the hook 654, the end of the hook 654 moves downward, and the rotating telescopic rod 655 is stretched at the same time. After the hook 654 moves to the position of the positioning groove 67, the previously stretched rotating telescopic rod 655 shrinks, so that the hook 654 is in the positioning groove 67. When the clamping device 3 is released and the mold 5 falls with the fixed frame 66, the hook 654 hooks the positioning groove 67 of the fixed frame 66, and the rotating rod 651 stretches the rotating telescopic rod 655 while rotating until the blocking block 653 presses against the bottom of the L-shaped plate 64, preventing the fixed frame 66 from falling further, thereby preventing the mold 5 from falling.

[0022] The fixing device 65 is provided to further fix the fixing frame 66 and the mold 5. By applying a pulling force to the fixing frame 66, when the hook 654 enters the positioning groove 67, the bidirectional screw 62 is rotated to drive the two L-shaped plates 64 away from each other, so that the inclined surface of the hook 654 and the triangular block 68 cooperate with each other, so that the hook 654 end of the rotating rod 651 converts the pulling force received into a part of the upward lifting force, so that the fixing device 65 is stably fixed in the positioning groove 67. At the same time, the pulling forces on both sides of the fixing frame 66 are opposite, so that the fixing frame 66 is subjected to opposite pulling forces at the same time, thereby tightening the fixing frame 66 and generating prestress on the side walls inside the fixing frame 66 to resist the thrust generated when the mold 5 is punched, so that the fixing frame 66 has a higher use strength, delays the damage time of the fixing frame 66, and thus allows the punching assembly of the punch press to be used for a longer time.
