The rotating shaft 402 is rotatably connected to the interior of the workbench 1 through a bearing, the gear 403 is welded to the outer surface of the rotating shaft 402, the tooth plate 404 is slidably connected to the interior of the workbench 1, and the support frame 405 is welded to one side of the tooth plate 404. The drive motor 401 connected to the rotating shaft 402 through a coupling is installed on the mounting plate at the front end of the workbench 1, and the gear 403 is meshed with the tooth plate 404. The two support frames 405 are symmetrically arranged with respect to the central axis of the workbench 1, and the support frame 405 is arranged in an inverted "U" shape. The first limit plate 406 and the second limit plate 407 are respectively arranged on both sides of the adjustment mechanism 5. The driving motor 401 works, and the output end of the driving motor 401 drives the rotating shaft 402 and the gear 403 to rotate, so that the tooth plate 404, the support frame 405 and the first limit plate 406 can slide in the horizontal direction, so that the plate to be stamped can be limited and clamped through the relatively arranged first limit plate 406, so that the plate to be stamped can be prevented from shaking or shifting, thereby improving the stamping accuracy, ensuring the processing quality, and facilitating use.

[0024] See also Figure 2 , Figure 3 and Figure 4 It can be seen that the top of the support frame 405 is provided with an adjustment mechanism 5, and the adjustment mechanism 5 is composed of a positioning frame 501, a positioning groove 502, a guide plate 503, a return spring 504, a limit column 505 and an adjustment plate 506. The limit column 505 is welded and connected to the top of the support frame 405, and the adjustment plate 506 is sleeved on the outer surface of the limit column 505, and the two sides of the adjustment plate 506 are welded and connected to the first limit plate 406 and the second limit plate 407. 07 are both symmetrically arranged with respect to the central axis of the workbench 1, the first limit plate 406 is arranged as a rectangular structure, and the second limit plate 407 is arranged as an arc structure. After the positioning frame 501 is separated from the positioning groove 502, the adjustment plate 506 can be rotated around the limit column 505, so that the position of the first limit plate 406 and the second limit plate 407 can be exchanged. In this way, the limit mechanism 4 can be applied to the limiting of various shapes of sheets to be punched without replacing the punching machine, thereby expanding the scope of application.

[0026] The working principle of the utility model is as follows: when using the convenient limited punching machine, the sheet to be punched is placed on the processing base 303, and the driving motor 401 is started. The output end of the driving motor 401 drives the rotating shaft 402 and the gear 403 to rotate, and then the tooth plate 404, the support frame 405 and the first limited plate 406 slide in the horizontal direction, so that the sheet to be punched can be limited and clamped by the first limited plate 406 arranged relatively. At this time, the hydraulic cylinder 301 is started, so that it extends and drives the punching plate 302 to move down to punch the sheet to be punched. During the stamping operation, when it is necessary to process the stamping sheet materials of other shapes, the positioning frame 501 can be pulled upward to disengage it from the positioning groove 502. At this time, the adjustment plate 506 can be rotated around the limiting column 505, so that the position of the first limiting plate 406 and the second limiting plate 407 can be exchanged. After loosening the positioning frame 501, it is reset under the action of the reset spring 504 and engaged with the positioning groove 502, thereby completing the adjusted positioning.
