[0023] 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.
[0024] Please see Figure 1-5This utility model provides a technical solution: a profile forming and core-pulling device for door and window processing, including an operating table 1, a mounting frame 2 fixed on the operating table 1, and a clamping component and a stamping component arranged inside the mounting frame 2. The stamping component is used for punching the profile, and the clamping component plays an auxiliary positioning role during the punching process to reduce the displacement of the profile and ensure the quality of profile preparation. A positioning frame 10 extending to the outside of the mounting frame 2 is fixed on the upper side of the operating table 1 near the clamping component, and a positioning seat 11 is fixed at the end of the positioning frame 10 away from the operating table 1. A positioning component is slidably arranged inside the positioning seat 11. The positioning component is used for limiting the profile. By limiting the profile, the stamping component is made to open the hole at the same position in the same batch of profiles. A core-pulling component and a demolding component are arranged on the side of the positioning frame 10. The core-pulling component is used for core pulling when the profile is opened. After the core pulling is completed, the demolding component assists in demolding the profile. A sliding hole is opened on the side of the positioning frame 10.
[0025] The core-pulling assembly includes a first positioning cylinder 15 installed in the positioning seat 11. A moving rod 16 is slidably arranged at one end of the first positioning cylinder 15 near the operating table 1. A first piston 18 located inside the first positioning cylinder 15 is installed at one end of the moving rod 16, and a core-pulling rod 17 located at the stamping assembly position is installed at the other end of the moving rod 16. An electric push rod 20 is installed on the side of the positioning frame 10. The telescopic end of the electric push rod 20 is fixedly connected to the side of the moving rod 16, and the connection between the electric push rod 20 and the moving rod 16 is set away from the first positioning cylinder 15. The moving rod 16 is driven to slide inside the first positioning cylinder 15 by the electric push rod 20, and the core-pulling rod 17 is controlled by the moving rod 16 to slide on the positioning frame 10 to assist in core pulling of the profile.
[0026] The demolding assembly includes a second positioning cylinder 21 installed on the lower side of the positioning frame 10. A connecting rod 22 is slidably provided at one end of the second positioning cylinder 21 near the operating table 1. A second piston 23 located inside the second positioning cylinder 21 is installed at one end of the connecting rod 22, and a push plate 24 is installed at the other end of the connecting rod 22. The push plate 24 is slidably disposed in a sliding hole. The sliding hole facilitates the demolding of the profile mounted on the positioning frame 10 by the push plate 24. The first positioning cylinder 15 and the second positioning cylinder 21 are connected by a connecting pipe, which is located away from the operating table 1. When the moving rod 16 drives the core-pulling rod 17 to slide out of the profile cavity, the first piston 23 at the end of the moving rod 16... Piston 18 compresses the air in the first positioning cylinder 15 and enters the second positioning cylinder 21 through the connecting pipe. The increased air pressure in the second positioning cylinder 21 pushes the second piston 23 to slide. The second piston 23 drives the connecting rod 22 to move, and the push plate 24 at the end of the connecting rod 22 pushes the profile on the operating table 1 to demold. Conversely, when the moving rod 16 drives the core-pulling rod 17 into the profile cavity, the second piston 23 drives the connecting rod 22 to return to the second positioning cylinder 21, achieving dynamic balance. Preferably, both the first positioning cylinder 15 and the second positioning cylinder 21 are filled with hydraulic oil 19, and a bracket 25 is provided on the lower side of the positioning frame 10 to support and position it.
[0027] The clamping assembly includes electric cylinders 8 installed on both sides of the mounting frame 2. Clamping plates 9 are installed at the telescopic ends of the electric cylinders 8. When processing the profile, the electric cylinders 8 on both sides of the mounting frame 2 are controlled to work, and the electric cylinders 8 push the clamping plates 9 to move and clamp the profile, reducing the displacement during profile processing. A limit seat 3 is installed on the upper side of the operating table 1, and the limit seat 3 is provided with a receiving hole that matches the profile. The limit seat 3 is replaceable and can be replaced according to the shape of the profile. The limit seat 3 is used for the initial positioning of the profile, which facilitates the use of the clamping assembly.
[0028] The stamping assembly includes a mounting plate 4 slidably disposed within the mounting bracket 2. A replaceable stamping die 5 is mounted on the lower side of the mounting plate 4. The stamping die 5 can be replaced according to the profile structure or punching requirements to meet the profile punching requirements. A hydraulic cylinder 6 is mounted on the upper side of the mounting bracket 2. The telescopic end of the hydraulic cylinder 6 is fixedly connected to the middle of the side of the mounting plate 4. The hydraulic cylinder 6 is controlled to work, and the mounting plate 4 is moved by the hydraulic cylinder 6 so that the stamping die 5 on the side of the mounting plate 4 punches holes in the profile.
[0029] Several sets of telescopic rods 7 are provided between the mounting plate 4 and the operating table 1. The fixed end of the telescopic rod 7 is connected and fixed to the lower side of the mounting plate 4, and the telescopic end of the telescopic rod 7 is connected and fixed to the upper side of the operating table 1. During the movement of the mounting plate 4 driven by the hydraulic cylinder 6, the telescopic rod 7 plays a positioning and guiding role, improving the stability of the mounting plate 4 when it is displaced.
[0030] The positioning assembly includes an adjusting plate 12 slidably disposed within the positioning base 11, and a positioning plate 13 is fixedly disposed on the upper side of the adjusting plate 12 near the operating table 1. The positioning plate 13 disposed at the end of the adjusting plate 12 limits the maximum sliding distance of the profile on the operating table 1. The positioning base 11 is provided with screws 14 for fixing the position of the adjusting plate 12. The position of the positioning plate 13 can be adjusted by sliding the adjusting plate 12 within the positioning base 11. By changing the distance between the positioning plate 13 and the stamping die 5, it is convenient to adjust and set the punching position of the profile to meet the punching requirements of the profile. The screws 14 are used for positioning the adjusting plate 12 after the position is adjusted to prevent the adjusting plate 12 from sliding during use.

Their working methods and circuit structures are all known technologies. The operation of the hydraulic cylinder 6, electric cylinder 8, and electric push rod 20 is controlled by setting a switch group or PLC controller on the operating table 1.
