Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile processing, in particular to a welding device for new energy automobile door panel processing. BACKGROUND

[0002] In the production process of a traditional automobile door, a reinforcing plate is welded at a door inner panel, which mainly serves to improve the load-carrying capacity, deformation resistance and overall rigidity of the door inner panel, thereby enhancing the safety and durability of the vehicle. The door inner panel welding reinforcing plate is usually made of high-strength steel, aluminum alloy or other lightweight high-strength materials, and the reinforcing plate is processed into a corrugated state, which can improve the local strength and rigidity of the reinforcing plate without increasing the material thickness.

[0003] The patent literature with the publication number CN118699655B provides a welding device for new energy automobile door panel processing, which comprises a base and a positioning plate fixedly installed on the top of the base. A partition plate is fixedly installed in the middle of the front surface of the positioning plate. A turnover plate is hingedly connected to the front end surface of the partition plate. A limiting mechanism for fixing the door reinforcing plate is arranged on the turnover plate. A scraping mechanism for cleaning the welding slag on the back surface of the turnover plate is arranged on the front surface of the positioning plate on one side of the partition plate. The two welding positions of the door reinforcing plate are preheated by the electric heating block, thereby reducing the welding stress and cracks generated by the door reinforcing plate and avoiding affecting the normal working efficiency. After the preheating of the two welding positions of the door reinforcing plate is completed, nitrogen gas passes through the air inlet hose and the two air injection pipes and is blown out from the two air injection pipes, thereby reducing the oxygen content around the two welding positions of the door reinforcing plate and improving the quality of the welding of the door reinforcing plate.

[0004] Although the device has many beneficial effects, it still has the following problems: the device uses a scraping mechanism to remove impurities on the surface of the turnover plate, but the electric heating block arranged on the surface of the turnover plate will block the cleaning area and affect the cleaning effect.

[0005] Secondly, the electric heating block of the device is positioned by sliding in the inclined slide and is pushed by the air cylinder. As the temperature rises, the air cylinder pressure is unstable, which will affect the normal movement. SUMMARY

[0006] This section aims to summarize some aspects of the embodiments of the application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of the specification to avoid obscuring the purpose of this section, abstract and title, and such simplifications or omissions cannot be used to limit the scope of the application.
