By aligning the connecting block 5 with the installation slot 4 and inserting it, the push-pull plate 13 is pushed to drive the moving block 11 to move to the right, so that it abuts against the transmission block 8 and drives the limit rod 9 to be inserted into the fixed slot 10, and the push-pull plate 13 is continued to be pushed The second slot 16 is moved outward, and then the rotating plate 20 is aligned with the second slot 16 and rotated to rotate the threaded rod 19, so that the moving block 11 is fixed, thereby completing the installation of the stamping die main body 2. When disassembly is required, the moving block 11 is released from the limit, and then the push-pull plate 13 is pulled back, so that the stamping die main body 2 can be quickly disassembled. The arrangement of the stamping die main body 2 can be quickly installed and disassembled, so that the stamping device main body 1 can spend less time when it needs to be replaced, thereby significantly improving the working efficiency of the stamping device main body 1 and reducing the tediousness of the staff's operation.

[0025] Reference Figure 2As shown, in the present embodiment: the surface of the limit rod 9 is slidably connected with a first return spring 17, and one end of the first return spring 17 close to the transmission block 8 is fixedly connected to the transmission block 8. Through the setting of the first return spring 17, when the moving block 11 is pulled back, the transmission block 8 is released from the limit. At this time, the elastic force stored in the first return spring 17 is released to drive the transmission block 8 to quickly reset, which is convenient for the next installation of the stamping die body 2.

[0026] Reference Figure 5 As shown, in the present embodiment: a first slide groove 21 is provided at the top and the bottom of the movable groove 3, a first slider 22 is fixed at the top and the bottom of the movable block 11, and the interior of the first slide groove 21 is slidably connected to the first slider 22.

[0027] Reference Figure 6 As shown, in the present embodiment: a third slot 23 is provided at one end of the moving block 11 close to the transmission block 8, the number of the third slots 23 is two and the insides are both rotatably connected with rollers 24 via a rotating shaft. Through the setting of the rollers 24, when the moving block 11 contacts the transmission block 8, the friction between the transmission block 8 and the moving block 11 can be reduced, thereby effectively reducing the mechanical wear of the device and improving its service life.

[0028] Reference Figure 7 As shown, in this embodiment: second slide grooves 25 are opened on both sides of the interior of the installation groove 4, second sliders 26 are fixed on both sides of the connecting block 5, and the interior of the second slide groove 25 is slidably connected to the second slider 26. Through the setting of the second slide groove 25 and the second slider 26, when the stamping die main body 2 is installed, the connecting block 5 can be slid into the installation groove 4 more conveniently, thereby further improving the installation efficiency of the stamping die main body 2.

[0029] Reference Figure 3 As shown, in the present embodiment: the surface of the first connecting rod 12 is slidably connected with a second return spring 27, the end of the second return spring 27 close to the moving block 11 is fixedly connected to the moving block 11, and the end of the second return spring 27 away from the moving block 11 is fixedly connected to the push-pull plate 13. Through the setting of the second return spring 27, when the moving block 11 is released from the limit, the elastic force stored in the second return spring 27 is released to drive the second return spring 27 to rebound quickly, thereby achieving a quick reset of the moving block 11 after use, which is convenient for the staff to use next time.

[0030] Reference Figure 3As shown, in this embodiment: the front end and the rear end of the moving block 11 are both installed with limit plates 28. Through the setting of the limit plates 28, the moving block 11 will not exceed the position of the transmission block 8 during the sliding process, thereby effectively preventing the moving block 11 from falling off due to moving too long a distance, and effectively improving the stability of the device during use.

[0031] Working principle: Align the connecting block 5 with the installation slot 4 and put it in, then push the push-pull plate 13 to drive the moving block 11 to move to the right, so that it abuts against the transmission block 8 and drives the limit rod 9 to insert into the fixed slot 10, continue to push the push-pull plate 13 to move the second slot 16 out, then align the rotating plate 20 with the second slot 16 and rotate it to turn the threaded rod 19 in, so that the moving block 11 is fixed, so that the installation of the stamping die body 2 is completed, when it is necessary to disassemble, release the limit of the moving block 11, and then pull the push-pull plate 13 back, so that the stamping die body 2 can be quickly disassembled. The arrangement of the stamping die body 2 can be quickly installed and disassembled, so that the stamping device body 1 can spend less time when it needs to be replaced, thereby significantly improving the working efficiency of the stamping device body 1 and reducing the tediousness of the operation of the staff. By setting the first reset spring 17, when the moving block 11 is pulled back, the transmission block 8 is released from the limit. At this time, the elastic force stored in the first reset spring 17 is released to drive the transmission block 8 to quickly reset, which is convenient for the next installation of the stamping die body 2. The setting can form a stable limiting effect during the movement of the moving block 11 in the moving groove 3, thereby improving the stability of the moving block 11 when moving. Through the setting of the roller 24, when the moving block 11 contacts the transmission block 8, the friction between the transmission block 8 and the moving block 11 can be reduced, thereby effectively reducing the mechanical wear of the device and improving the service life. Through the setting of the second slide groove 25 and the second slider 26, when the stamping die body 2 is installed, the connecting block 5 can be more conveniently slid into the installation groove 4, thereby further improving the installation efficiency of the stamping die body 2. Through the setting of the second return spring 27, when the moving block 11 is released from the limit, the elastic force stored in the second return spring 27 is released to drive the second return spring 27 to rebound quickly, thereby achieving a quick reset of the moving block 11 after use, which is convenient for the staff to use next time. Through the setting of the limiting plate 28, the moving block 11 will not exceed the position of the transmission block 8 during the sliding process, thereby effectively preventing the moving block 11 from falling off due to the long moving distance, and effectively improving the stability of the device when in use.
