[0028] Referring to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: a multi-station progressive die with a safety protection device, including:

[0029] A bottom plate 1, on the upper surface of which a lower die 2 is fixedly connected. The bottom plate 1 is used for the stable operation of the lower die 2;

[0030] An upper die 3, which is arranged directly above the bottom plate 1. On one side of the outer wall of the upper die 3, a rack column 4 is fixedly connected. The upper die 3 is connected to a driving end for driving the rack column 4 to move;

[0031] A stabilizing block 5, the lower surface of which is fixedly connected to one side of the upper surface of the bottom plate 1.

[0033] A first telescopic rod 9, one end of which is fixedly connected to one side of the outer wall of the hinge seat 8, and the other end of which is fixedly connected to one side of the outer wall of the sliding plate 10; the rack column 4 penetrates through the bottom plate 1 and is meshed with the gear 6. The lower surface of the second hinge block 26 is fixedly connected to the upper surface of the bottom plate 1. The first hinge block 15 is slidably connected inside the bottom plate 1. On one side of the outer wall of the second protection plate 14, it is slidably connected inside the sliding plate 10;

[0034] Specifically, when the upper die 3 starts to operate through the driving end, it receives power and drives the rack column 4 to perform a stamping motion downward; at the same time, the upper die 3 drives the rack column 4 to engage and rotate precisely with the stabilizing block 5; through the rotation of the connecting plate 7, the hinge seat 8 starts to rotate synchronously; with the movement of the hinge seat 8, the first telescopic rod 9 is driven to perform telescopic operation; during the telescopic process, the first telescopic rod 9 simultaneously drives the sliding plate 10 to slide up and down inside the limiting column 11; the movement of the sliding plate 10 further drives a plurality of first protective plates 12 and second protective plates 14 to rotate on the rotating shaft 13; with the sliding of the second protective plate 14 and the first hinge block 15, the sliding plate 10 is lifted and raised, thus preventing workers from entering the working area; when the upper die 3 presses down, the sliding plate 10 is raised, providing effective safety protection to ensure the safety of workers' operations; in this way, through the downward pressing motion of the upper die 3, not only the stamping task is completed, but also the safety protection of the working area is realized, preventing accidents from occurring.

[0035] Refer to Figure 2 、 Figure 3 and Figure 4 , a plug rod 16 is slidably connected inside the bottom plate 1, and a fixing block 17 is fixedly connected to the upper surface of the plug rod 16; a second telescopic rod 18 is fixedly connected to the lower surface of the fixing block 17, and a first spring 19 is sleeved on the outer wall of the second telescopic rod 18; the lower surface of the first spring 19 is rotatably connected to a connecting rod 20, and the connecting rods 20 are arranged symmetrically left and right at equal intervals; the outer walls of the two connecting rods 20 are both rotatably connected to a clamping block 21, and the two clamping blocks 21 are rotatably connected to one side inside the plug rod 16; a fixing seat 22 is fixedly connected to the upper surface of the fixing block 17, and a stabilizing plate 23 is rotatably connected to one side of the inner wall of the fixing seat 22; a T-shaped rod 24 is slidably connected inside the stabilizing plate 23, and a second spring 25 is arranged on one side of the outer wall of the T-shaped rod 24, and the second spring 25 is slidably connected inside the fixing seat 22;

[0036] Specifically, by inserting the insertion rod 16 into the interior of the base plate 1, when the insertion rod 16 is inserted into the interior of the base plate 1, the telescopic force of the first spring 19 will drive the second telescopic rod 18 to simultaneously perform precise telescopic movements; at this time, the first spring 19 further drives the connecting rod 20 to rotate smoothly, thereby realizing the firm engagement of the clamping block 21 inside the base plate 1 and ensuring the stable fixation of the entire device; then, the lower mold 2 is accurately placed above the base plate 1, and the lower mold 2 is accurately positioned through the fixing block 17 to ensure its accurate position; then, by pulling the stabilizing plate 23, the T-shaped rod 24 is made to compress the second spring 25 and contract. After releasing the stabilizing plate 23, the second spring 25 will push the T-shaped rod 24 to quickly rotate, thereby realizing driving the stabilizing plate 23 to firmly abut against the outer wall of the lower mold 2; in this way, the rapid positioning and stable installation of the lower mold 2 are achieved, which not only improves the installation efficiency but also ensures the stability and safety of the lower mold 2 during operation; this series of operation processes are precise and efficient, fully reflecting the rationality and practicality of the device design.

[0037] Working principle: When in use, first, when the upper mold 3 operates through the driving end, at this time, the upper mold 3 receives power to drive the rack column 4 to move downward in a stamping motion. At this time, the upper mold 3 drives the rack column 4 to engage and rotate with the stabilizing block 5. At this time, the connecting plate 7 rotates to make the hinge seat 8 rotate. At this time, the movement of the hinge seat 8 further drives the first telescopic rod 9 to expand and contract. At this time, while the first telescopic rod 9 expands and contracts, it will drive the sliding plate 10 to slide up and down inside the limiting column 11. At this time, through the movement of the sliding plate 10, the effect of driving a plurality of first protective plates 12 and second protective plates 14 to rotate on the rotating shaft 13 is realized. Then, through the sliding of the second protective plate 14 and the first hinge block 15, the effect of facilitating the lifting of the sliding plate 10 is realized. When the upper mold 3 presses down, the sliding plate 10 is raised to prevent workers from entering the working area.

[0038] Secondly, when it needs to be installed on different machine tools, at this time, the insertion rod 16 is inserted into the interior of the base plate 1. When the insertion rod 16 is inserted into the interior of the base plate 1, at this time, the telescopic force of the first spring 19 will drive the second telescopic rod 18 to expand and contract simultaneously. At this time, the first spring 19 further drives the connecting rod 20 to rotate, thereby realizing driving the clamping block 21 to engage and fix inside the base plate 1. At this time, the lower mold 2 is placed above the base plate 1. At this time, the lower mold 2 is positioned through the fixing block 17. At this time, by pulling the stabilizing plate 23, the T-shaped rod 24 is made to compress the second spring 25 and contract. At this time, when the stabilizing plate 23 is released, the second spring 25 will push the T-shaped rod 24 to rotate, thereby realizing driving the stabilizing plate 23 to abut against the outer wall of the lower mold 2, and further realizing the effect of quick positioning and convenient installation while.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
