[0002] As an important part of modern architecture, metal curtain walls are widely used in various commercial and public buildings due to their excellent fire prevention, heat insulation, sound insulation, waterproof and decorative properties. Metal curtain walls use metal plates as panel materials and combine advanced processing technologies to form a unique aesthetic and highly practical building appearance. However, in the process of metal curtain wall processing, especially in the bending process of metal curtain wall panels, there are many technical challenges.

[0003] Currently, the bending operation of metal curtain wall panels generally relies on manual assistance for positioning and lifting. This process not only has a high labor intensity, but also is difficult to ensure the accuracy and consistency of bending.

[0015] The beneficial effects achieved by the present invention with the above structure are as follows: The present invention provides a bending device for metal curtain wall processing, achieving the following beneficial effects:

[0016] (1) To solve the problem that long-term bending operations cause extremely serious tool wear, not only reducing the processing efficiency but also frequently triggering tool repair requirements, significantly increasing production time and costs. With the bending assistance mechanism of the present invention, due to the use of lubricant, tool wear and failure rates are reduced, so the downtime caused by tool replacement is reduced.

[0017] (2) Through the bending assistance mechanism, the lubricant can form a lubricating film between the metal curtain wall plate and the tool, significantly reducing the friction coefficient between the two, making the bending process smoother. Reducing friction also means reducing tool wear, thereby extending the service life of the tool and reducing production costs.

[0018] (3) Through the bending assistance mechanism, scratches and indentations on the surface of the metal curtain wall plate during the bending process can be reduced, maintaining its good appearance quality.

[0019] (4) Nitrogen has a certain cooling effect when sprayed, which helps to reduce the temperature of the metal curtain wall plate during the bending process, reducing deformation and errors caused by thermal expansion. Nitrogen is an inert gas and is not easily chemically reactive with other substances. During the bending process, nitrogen can isolate oxygen in the air, preventing the metal curtain wall plate from undergoing an oxidation reaction with oxygen at high temperatures, thereby protecting the metal surface from oxidation corrosion.

[0020] (5) Through the plastic strengthening component, the temperature of the metal curtain wall plate can be increased, reducing its yield strength and tensile strength, thereby improving the plasticity of the material, making the material more likely to undergo plastic deformation during the bending process, reducing the bending force, facilitating the smooth progress of the bending process, and being able to reduce stress concentration and cracking risks during the bending process, improving the bending quality.

[0021] (6) Through the cooling component, after heating, appropriate temperature reduction treatment can be carried out to enable the metal curtain wall plate to maintain a certain shape stability after bending, preventing dimensional changes caused by temperature changes.

[0022] (7) To further improve the practicality and popularizability, the present invention proposes a feeding mechanism for metal curtain wall panels, which can realize the automatic feeding of metal curtain wall panels.

[0023] (8) The setting of the lifting component replaces manual auxiliary positioning and lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Lubricant is provided in the lubricant storage cavity 18, and nitrogen is provided in the nitrogen storage tank 24.

[0049] During specific use, first place the metal curtain wall panel on the angle adjustment table 13. The output end of the motor 41 rotates to drive the rotation of the rotating shaft 35. The rotation of the rotating shaft 35 drives the rotation of the first roller 36. The rotation of the first roller 36 drives the rotation of the conveyor belt 37. The rotation of the conveyor belt 37 drives the movement of the metal curtain wall panel. When passing through the second roller 45, the metal curtain wall panel is pressed by the spring 43. During the movement of the metal curtain wall panel, start the heating blower 52. The hot air flow generated blows towards the bottom surface of the metal curtain wall panel through the heating holes 32 to heat the metal curtain wall panel. Heating can increase the temperature of the metal curtain wall panel, reduce its yield strength and tensile strength, thereby improving the plasticity of the material. When the metal curtain wall panel moves above the extrusion groove 10, the output end of the first cylinder 39 moves downward to drive the pressing plate 40 to move downward. The pressing plate 40 fixes the metal curtain wall panel. Start the ultrasonic atomizing sheet 21 and the refrigeration component 25. Open the pressure reducing valve 27 and the second electronic valve 28. After the lubricant in the lubricant storage cavity 18 is atomized by the ultrasonic atomizing sheet 21, the nitrogen gas compressed in the nitrogen storage tank 24 enters the mixing cavity 17 through the output pipe 26. After being cooled by the refrigeration component 25 and mixed with the atomized lubricant, it enters the spray head 23 through the corrugated expansion pipe 22 and is sprayed towards the bending part of the metal curtain wall panel through the spray head 23. The lubricant can form a lubricating film between the metal curtain wall panel and the mold, significantly reducing the friction coefficient between the two, making the bending process smoother. The nitrogen gas has a certain cooling effect when sprayed, which helps to reduce the temperature of the metal curtain wall panel during the bending process, reducing the deformation and error caused by thermal expansion. Nitrogen gas can isolate oxygen in the air, preventing the metal curtain wall panel from reacting with oxygen at high temperatures, thereby protecting the metal surface from oxidation corrosion. At the same time, the output end of the hydraulic cylinder 8 moves downward to drive the tool 11 to move downward to bend the metal curtain wall panel. The output end of the second cylinder 50 moves to drive one end of the angle adjustment table 13 to lift upward, thereby assisting in bending the metal curtain wall panel. Then the output end of the second cylinder 50 resets. The above is the overall working process of the present invention. Just repeat this step when using it next time.
