[0002] A drawing die generally refers to various dies for drawing metal wires, and also a wire drawing die for drawing optical fibers. There is a hole with a certain shape in the center of all wire drawing dies. When the metal is drawn through the die hole, its size becomes smaller and even its shape changes.

[0003] During the production of cold-drawn wire, the loss of the die is extremely large. After the die is used for a period of time, certain damages will occur. The damaged die will reduce the processing quality of the cold-drawn wire. Existing dies are generally fixedly installed on the cold-drawn wire production line. It is rather cumbersome for operators to replace the die, time-consuming and laborious, and the operation cost is relatively high. Content of the Utility Model

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Embodiment: As Figures 1-5As shown in the figure, the utility model provides a quick die-changing device for a cold-drawn wire production line, including a die 1. An upper shell cover 11 is arranged directly above the die 1, and a lower shell cover 12 is arranged directly below the die 1. The upper shell cover 11 and the lower shell cover 12 are used in cooperation. Mirror-image distributed connection grooves 2 are formed at the top of the lower shell cover 12. Mirror-image distributed connecting plates 21 are fixedly arranged at the bottom end of the upper shell cover 11. A plurality of connection blocks 22 distributed in an array are fixedly arranged on the lower surface of the connecting plate 21. A plurality of fixing grooves 23 distributed in an array are formed inside the lower shell cover 12. The fixing grooves 23 are used in cooperation with the connection blocks 22. A plurality of first springs 27 distributed in an array are arranged in the lower shell cover 12. One end of each first spring 27 is fixedly provided with a moving disk 26. The end of the first spring 27 far from the moving disk 26 is fixedly installed on the inner wall of the lower shell cover 12. Moving plates 24 are fixedly arranged at the top ends of the moving disks 26. Blocks 25 are fixedly arranged on one side of each moving plate 24. Card slots 28 are formed in each connection block 22. The blocks 25 are used in cooperation with the card slots 28.

[0019] Reinforcing plates 3 are fixedly arranged on the outer surfaces of the moving disks 26 in a mirror-image distribution. Second springs 31 are fixedly arranged on one side of each reinforcing plate 3. The end of the second spring 31 far from the reinforcing plate 3 is fixedly installed on the inner wall of the lower shell cover 12.

[0020] A first installation groove 110 is formed in the upper shell cover 11, and a second installation groove 120 is formed in the lower shell cover 12. The first installation groove 110 and the second installation groove 120 are used in cooperation.

[0021] The moving disks 26 are distributed in two groups. A driving rod 210 is fixedly inserted through the two moving disks 26 in each group. The driving rod 210 slidably penetrates through the lower shell cover 12.

[0022] Handles 220 are fixedly arranged at one end of each driving rod 210.

[0023] Guide rods 310 are slidably inserted through the reinforcing plates 3. The two ends of the guide rods 310 are fixedly installed on the inner wall of the lower shell cover 12. By arranging the guide rods 310, the effect of limiting the reinforcing plates 3 is achieved, so that the reinforcing plates 3 can move stably.

[0024] The moving plates 24 are slidably connected to the inner wall of the lower shell cover 12. By slidably connecting the moving plates 24 to the inner wall of the lower shell cover 12, the moving plates 24 can move stably.

[0025] The moving disks 26 are slidably connected to the inner wall of the lower shell cover 12. By slidably connecting the moving disks 26 to the inner wall of the lower shell cover 12, the moving disks 26 can move stably.

[0026] Working principle: First, the bottom cover 12 of the shell and the cold wire drawing production line are fixedly installed. When the mold 1 needs to be replaced, the driving handle 220 is used to drive the driving rod 210 to move, and the driving rod 210 drives the moving disk 26 to move. During the movement, the moving disk 26 drives the moving plate 24 and the reinforcement plate 3 to move. During the movement of the moving disk 26 and the reinforcement plate 3, the first spring 27 and the second spring 31 are compressed and deformed. During the movement, the moving plate 24 drives the card block 25 to move. When the card block 25 completely leaves the card slot 28, the connecting block 22 is removed from the fixed slot 23, and the connecting plate 21 is removed from the connecting slot 2 to complete the disassembly between the shell upper cover 11 and the shell bottom cover 12. , then, take out the damaged mold 1 in the first mounting groove 110 and the second mounting groove 120, put the new mold 1 into the second mounting groove 120, put the connecting plate 21 into the connecting groove 2, and put the connecting block 22 into the fixing groove 23. At this time, the new mold 1 is located in the first mounting groove 110 and the second mounting groove 120. Remove the driving force of the handle 220. At this time, the first spring 27 and the second spring 31 elastically reset. Driven by the reset elastic force of the first spring 27 and the second spring 31, the movable plate 26 and the reinforcement plate 3 move, and the movable plate 26 drives the movable plate 24 to move, and the movable plate 24 drives the block 25 to move. When the block 25 completely enters the slot 28, the replacement of the mold 1 is completed.

[0027] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
