[0015] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a bending device for metal curtain wall processing, which achieves the following beneficial effects: (1) In order to solve the problem that long-term bending operations cause extremely serious wear on the tool, which not only reduces the processing efficiency but also frequently triggers the need for tool maintenance, significantly increasing production time and costs, the present invention uses a bending auxiliary mechanism to reduce tool wear and failure rate due to the use of lubricants, thereby reducing downtime due to tool replacement.

[0016] (2) Through the bending auxiliary mechanism, the lubricant can form a lubricating film between the metal curtain wall panel 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 tool's service life and reducing production costs.

[0017] (3) The bending auxiliary mechanism can reduce scratches and indentations on the surface of the metal curtain wall panel during the bending process, maintaining its good appearance quality.

[0018] (4) Nitrogen has a certain cooling effect when it is sprayed out, which helps to lower the temperature of the metal curtain wall panel during the bending process and reduce the deformation and error caused by thermal expansion. Nitrogen is an inert gas and is not easy to react chemically with other substances. During the bending process, nitrogen can isolate the oxygen in the air and prevent the metal curtain wall panel from undergoing an oxidation reaction with oxygen at high temperature, thereby protecting the metal surface from oxidative corrosion.

[0019] (5) Through the plastic strengthening components, the temperature of the metal curtain wall panel can be increased, and its yield strength and tensile strength can be reduced, thereby improving the plasticity of the material, making it easier for the material to undergo plastic deformation during the bending process, reducing the bending force, and facilitating the smooth progress of the bending process. It can reduce the stress concentration and cracking risk generated during the bending process and improve the bending quality.

[0020] (6) By cooling the components and performing appropriate cooling treatment after heating, the metal curtain wall panels can maintain a certain shape stability after bending and prevent dimensional changes caused by temperature changes.

[0021] (7) In order to further improve the practicability and scalability, the present invention proposes a metal curtain wall panel loading mechanism, which can realize the automatic loading of the metal curtain wall panel.

[0022] (8) The setting of the lifting assembly replaces the manual assisted positioning and lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The lubricant storage chamber 18 is filled with lubricant, and the nitrogen storage tank 24 is filled with nitrogen.

[0039] When in use, first place the metal curtain wall panel on the angle adjustment platform 13, the output end of the motor 41 rotates to drive the rotating shaft 35 to rotate, the rotating shaft 35 rotates to drive the roller 1 36 to rotate, the roller 1 36 rotates to drive the transmission belt 37 to rotate, the transmission belt 37 rotates to drive the metal curtain wall panel to move, and the spring 43 is used to press the metal curtain wall panel when passing the roller 2 45. During the movement of the metal curtain wall panel, the heating fan 52 is started, and the generated hot air flow is blown to the bottom surface of the metal curtain wall panel through the heating hole 32, thereby heating the metal curtain wall The plate is heated, and heating can increase the temperature of the metal curtain wall plate, reduce its yield strength and tensile strength, and thus improve the plasticity of the material.

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 has a certain cooling effect when it is sprayed, which helps to reduce the temperature of the metal curtain wall panel during the bending process and reduce the deformation and error caused by thermal expansion. The nitrogen can isolate the oxygen in the air and prevent the metal curtain wall panel from oxidizing with oxygen at high temperature, 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 cylinder 2 50 moves to drive one end of the angle adjustment platform 13 to lift upward, thereby assisting the bending of the metal curtain wall panel. After that, the output end of the cylinder 2 50 is reset. The above is the overall workflow of the present invention. Repeat this step when you use it next time.
