The second hinge seat 738 is fixedly connected to the bottom of the second connecting plate 718.

[0030] When in use, the operation of the two-way telescopic rod 732 pushes the connecting plates 733 at both ends synchronously, and the movement of the connecting plate 733 makes the sliding sleeve 734 slide on the guide rod 736, thereby making the connecting rod 737 rotate on the first hinge seat 735, and the connecting rod 737 rotates on the second hinge seat 738 and pushes the installation cavity 723 to move, so that the second connecting plate 718 slides through the push of the connecting rod 737, thereby making the third support frame 714 slide inside the second support frame 713. When the third support frame 714 slides to be flush with the first support frame 712, the mold base 6 of this specification can be supported and installed according to the matching frame 601 that matches the inside of the third support frame 714. At the same time, through the setting of the support seat 715, the bottom of the mold base 6 can be stably supported, thereby ensuring the stability of the metal blank processing and improving its processing quality.

[0031] This solution has the following working process: when this device is used, the die base 6 is installed in the installation groove 602 through the matching frame 601, and by placing the metal blank on it, the hydraulic cylinder 4 is operated to push the mounting base 401 to slide stably under the limit of the limit rod 402, so that the metal blank is processed by the die head 5. When the die base 6 of different specifications is replaced, it is placed in the installation groove 602 for installation through the matching frame 601 set according to different specifications, and the matching frame 601 of different specifications can be adjusted accordingly through the setting of the installation adjustment mechanism 7. The corresponding matching support adjustment can enable the matching frame 601 to perform a stably installed and limited operation in the installation groove 602, thereby improving the stability of the processing, and when the mold base 6 is replaced, the setting of the matching adjustment component 71 facilitates the pushing out operation of the installed mold base 6, thereby facilitating its removal and replacement, thereby improving its installation efficiency, and in conjunction with the setting of the first support component 72 and the second support component 73, it is possible to respectively perform installation and support work on matching frames 601 of different specifications, thereby improving its stability and ensuring the processing quality of the metal blank.

[0032] In summary: through the installation and adjustment mechanism 7, it is convenient to stably support the die base 6 on the processing table 1, thereby improving its stability during the processing, ensuring the processing quality of the metal blank, and thus improving its production efficiency; through the installation and adjustment mechanism 7, under the setting of the matching adjustment component 71, it is possible to support and limit the die base 6 according to different specifications, and cooperate with the operation of the first support component 72 and the second support component 73, so that the matching adjustment component 71 can stably support and limit the die base 6 of the corresponding specifications, thereby improving its practicality.
