Description

TECHNICAL FIELD

[0001] The application relates to the technical field of fireproof door production, in particular to a welding auxiliary fixing frame for fireproof door production. BACKGROUND

[0002] The fireproof door refers to a door capable of meeting the requirements of fire resistance stability, integrity and heat insulation for a certain time. The fireproof door is a fireproof partition provided between fireproof compartments, evacuation staircases, vertical shafts and the like and has a certain fire resistance. In the production process of the fireproof door, welding is a crucial link. The welding quality directly determines the structural strength and overall stability of the fireproof door and has a key influence on whether the fireproof door can effectively play the fireproof function in an emergency such as fire. The fireproof door is usually composed of a door frame, a door plate and the like. The components need to be firmly connected together through welding.

[0003] In the traditional welding process of the fireproof door, some simple clamps or manual holding methods are usually used to fix the components to be welded. For small fireproof doors or fireproof doors with simple structures, these methods can perhaps barely meet the requirements. However, with the design of the fireproof door being more and more diversified, the size gradually increasing and the structure being more and more complex, for example, in the welding of a large fireproof door, due to the large weight, the stability in the welding process is difficult to guarantee by manual holding, and the deviation of the welding position is easily caused. Moreover, the heat generated in the welding process will cause thermal deformation of the components. If there is no effective fixing measure, the deformation may exceed the allowable range, thereby affecting the assembly precision and quality of the fireproof door and having certain limitations in use.
