[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a stamping device for punching the end of a profile, including a worktable 1, a frame 2 fixed on the upper side of the worktable 1, a punching seat 3 located inside the frame 2 installed on the upper side of the worktable 1, and symmetrical placement openings adapted to the profile are arranged on the side of the punching seat 3. It should be noted that this stamping device is used for punching convex profiles. When punching profiles of other shapes, the punching seat 3 can be replaced. There are two placement openings, and the placement openings are horizontal convex structure. One placement opening is used for punching the protruding part of the profile, and the other is used for punching the remaining part of the profile. The separate punching method reduces the deformation of the profile during the punching process and ensures the processing quality of the profile.

[0018] A punching die is provided on the upper side of the frame 2 at the position corresponding to the punching seat 3. As described above, when changing the punching seat 3 for punching profiles of other shapes, the punching die must be changed simultaneously. The punching die is used to punch the profile in the placement opening. The upper side of the punching seat 3 has a punching groove that communicates with the placement opening, and the punching groove passes through the punching seat 3 and extends to the lower side of the worktable 1.

The first baffle 5 is used to limit the punching of the protruding part of the profile, and the second baffle 6 is used to limit the remaining part of the profile. The limiting mechanism during partial punching is provided by the first baffle 5 and the second baffle 6, which are set separately. Punching plates 7 are installed on the side of the first baffle 5 near the placement opening and on the side of the second baffle 6 near the placement opening. The punching plates 7 are adjusted to be in the placement opening, and then the end of the profile is inserted into the placement opening. The baffle in the placement opening limits the end of the profile so that the end of the profile is just in the punching groove. At this time, the punching plates 7 are inside the profile. The baffle is moved in the punching groove by the moving drive of the mounting base 4, so that the punching plates 7 installed on the side of the baffle punch the end of the profile for profile end processing.

[0019] Preferably, a hydraulic cylinder 8 is installed on the side of the frame 2, and the mounting base 4 is fixedly installed on the telescopic end of the hydraulic cylinder 8. A hydraulic station 9 is provided below the workbench 1 to control the telescopic movement of the hydraulic cylinder 8.

The profile is positioned according to the required punching position. Then, the servo motor 17 is controlled to drive the adjusting rod 16 to rotate. The adjusting rod 16 drives the threaded cylinder under the action of the threads to move the clamping plates 15. The profile is clamped and positioned by the clamping plates 15 and the fixing plate 14, and the clamped profile corresponds exactly to the placement opening. The positioning assembly plays a supporting and positioning role for the profile, reducing the tilting and sliding phenomenon caused by the unstable center of gravity of the profile during end punching.

[0023] The drive assembly includes an electric telescopic rod 11 installed on the side of the workbench 1. The telescopic end of the electric telescopic rod 11 is connected and fixed to the side of the positioning frame 13. Controlling the operation of the electric telescopic rod 11 drives the positioning frame 13 to move, which facilitates the movement of the profile fixed on the positioning assembly into the placement opening for punching. At the same time, the electric telescopic rod 11 can drive the positioning frame 13 to move and remove the profile from the placement opening, which facilitates the picking and placing of the profile on the positioning assembly. A guide rod 12 is fixed on the positioning frame 13. The guide rod 12 is slidably connected to the workbench 1. During the movement of the positioning frame 13, the guide rod 12 plays a positioning and guiding role, which improves the stability and structural strength of the positioning frame 13 during use.

[0024] The hydraulic cylinder 8, hydraulic station 9, electric telescopic rod 11, servo motor 17, etc. used in this utility model are all commonly used electronic components in the prior art. Their working methods and circuit structures are all known technologies. The operation of the hydraulic station 9, electric telescopic rod 11, servo motor 17 and other electronic components is controlled by setting a switch group or PLC controller on the workbench 1. This method is a common technical means used by technicians and will not be described in detail here.

[0025] During the punching process, the profile can be supported and positioned to prevent overall tilting or even falling off due to instability of the center of gravity during the end punching process. This ensures effective punching of the profile end and reduces punching errors caused by profile tilting and sliding. In addition, this stamping device facilitates the discharge of stamping debris, preventing debris from accumulating in the punching groove and affecting the use of the punching die, thus facilitating the processing and preparation of the profile.
