An existing steel plate roll forming device (publication number: CN214078966U) has the following disadvantages in use:

[0003] During the rolling process of the workpiece, the pressure roller continuously contacts the surface of the workpiece for rolling. However, after a period of rolling, the surface temperature of the pressure roller will rise. Long-term high temperature on the surface of the pressure roller will cause the hardness of the pressure roller material to decrease, thereby reducing its wear resistance and wear resistance. To solve the above problems, this patent proposes a roller forming device for door frames. Utility Model Content

[0019] 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.

[0020] The door frame roll forming device is a special equipment used to manufacture door frames. Through the roll forming process, metal materials (such as steel, aluminum, etc.) are processed into door frames of specific shapes and sizes. In the process of processing the door frame using the roll forming device, the first rotating rod 4, the second rotating rod 5, the rotating roller 6 and the pressure roller 7 can be cooled down, thereby avoiding the high temperature of the rotating roller 6 and the pressure roller 7, which would lead to a decrease in the hardness of the materials of the rotating roller 6 and the pressure roller 7, reduce their wear resistance and wear resistance.

[0021] like Figures 1-5As shown, this utility model provides a technical solution: a roll forming device for door frames, including a workbench 1, a first connecting frame 2 and a second connecting frame 3 fixed at the top of the workbench 1, mounting plates slidably connected between the inner walls of both ends of the first connecting frame 2 and the second connecting frame 3, a plurality of first rotating rods 4 rotatably connected through the two mounting plates, a plurality of second rotating rods 5 rotatably connected through the inner walls of both sides of the workbench 1, rotating rollers 6 fixed to the outer walls of the first rotating rods 4 and the first rotating rods 4 fixed to the outer walls of the first rotating rods 4, a pressure roller 7 fixed to the outer wall of the first rotating rods 4, a first refrigeration box 8 and a second refrigeration box 9 fixed to one side of the workbench 1, a first water pump and a second water pump installed inside the first refrigeration box 8, and a first refrigeration pipe 10 fixedly connected to the outlet of the first water pump. The outlet of the second water pump is fixedly connected to the second refrigeration pipe 11. The first refrigeration pipe 10 and the second refrigeration pipe 11 pass through the mounting plate and are rotatably connected to the first rotating rod 4 and the second rotating rod 5 respectively. The first refrigeration pipe 10 and the second refrigeration pipe 11 are fixedly connected to the second refrigeration box 9. The top of the first refrigeration box 8 and the second refrigeration box 9 are both fixedly connected to the water inlet pipe. The top of the first connecting frame 2 and the second connecting frame 3 are both fixedly connected to the telescopic rod 17. The telescopic end of the telescopic rod 17 is fixed to the mounting plate. Multiple semiconductor cooling chips 12 are installed inside the first refrigeration box 8 and the second refrigeration box 9. The second refrigeration box 9 is equipped with a third water pump. The outlet of the third water pump is fixedly connected to the delivery pipe 25. The delivery pipe 25 is fixedly connected to the first refrigeration box 8.

[0022] It should be noted that the rotating roller 6 drives the door frame to move, and the pressure roller 7 rolls the door frame to form it. By setting up a first refrigeration box 8 and a second refrigeration box 9, the first refrigeration box 8 and the second refrigeration box 9 are cooled by a semiconductor refrigeration chip 12. The principle of the semiconductor refrigeration chip 12 is that when the current flows from the P-type material to the N-type material, one side of the contact will absorb heat, causing the temperature on that side to decrease; while the other side will release heat, causing the temperature to rise. The side with the lower temperature is located in the first refrigeration box 8 and the second refrigeration box 9, which cools the water inside. In addition, fans can be installed on the outside of the first refrigeration box 8 and the second refrigeration box 9. The fans cool the side of the semiconductor refrigeration chip 12 that releases heat. The cooled water is pumped by the first water pump and the second water pump, and then flows into the second refrigeration box 9 through the first refrigeration pipe 10 and the second refrigeration pipe 11 respectively, and continues to be cooled. Then the water in the second refrigeration box 9 is transported back to the first refrigeration box 8 through the third water pump and the delivery pipe 25 to achieve circulation.

[0023] like Figure 2 and Figure 5As shown, the top of the first refrigeration box 8 and the second refrigeration box 9 are both rotatably connected to the mounting rod 26. Multiple stirring rods 27 are fixed to the outer wall of the mounting rod 26. A rotating wheel 13 is fixed to the outer wall of the top of the mounting rod 26. A belt 14 is arranged between the rotating wheels 13. A fixing frame 15 is fixed to the top of the first refrigeration box 8. A first motor 16 is fixed to the top of the fixing frame 15. The output end of the first motor 16 passes through the fixing frame 15 and is fixed to the mounting rod 26.

[0024] It should be noted that by starting the first motor 16, the first motor 16 drives the mounting rod 26 to rotate. The rotation of the mounting rod 26 drives one of the rotating wheels 13 to rotate, which in turn causes the belt 14 to move. The movement of the belt 14 drives the other rotating wheel 13 to rotate, ultimately causing both mounting rods 26 to rotate. In this way, the stirring rod 27 drives the water to stir, making the water in the first refrigeration box 8 and the second refrigeration box 9 cool evenly.

[0025] like Figure 2 and Figure 3 As shown, a first worm gear 23 is fixed to the outer wall of the second rotating rod 5 located outside the workbench 1, and a second worm gear 24 is fixed to the outer wall of the first rotating rod 4 located outside the mounting plate. A mounting frame 18 is fixed to the other side of the workbench 1. A rotating rod 19 is rotatably connected to the top of the mounting frame 18. A second motor is fixed to the bottom of the mounting frame 18. The output end of the second motor passes through the mounting frame 18 and is fixed to the rotating rod 19. A first worm 20 is fixed to the outer wall of the rotating rod 19. A second worm 22 is slidably connected to the outer wall of the rotating rod 19. The first worm 20 meshes with the first worm gear 23, and the second worm 22 meshes with the second worm gear 24. A groove 21 is opened on the outer wall of the rotating rod 19. A connecting block is fixed to the inner wall of the second worm 22. The connecting block slides in the groove 21. A connecting plate is fixed to the other side of the mounting plate. The second worm 22 and the second worm gear 24 are rotatably connected to the bottom and one side of the connecting plate, respectively. A controller is fixed at one end of the first connecting frame 2. The controller is electrically connected to the first motor 16, the second motor, and the telescopic rod 17. In this solution, the control method of the electrical components is controlled by the peripheral controller that is matched with them. The control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the art. It is used without modification. In addition, this utility model is mainly used to protect mechanical devices. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0026] It should be noted that by starting the second motor, the second motor drives the rotating rod 19 to rotate, the rotating rod 19 drives the first worm 20 to rotate, the first worm 20 drives the second worm 22 to rotate, and the rotation of the first worm 20 and the second worm 22 respectively drives the first worm wheel 23 and the second worm wheel 24 to rotate, so that the second rotating rod 5 and the first rotating rod 4 rotate.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
