Huayuan stainless steel revolving door supply

  The structure of the anti-theft door is mainly the bending of the outer door panel and the inner door panel, and then the bent inner and outer door panels are stacked and welded
Before welding, the cavity formed between the inner and outer door panels is filled with the required filler
The welding of the inner and outer door panels is generally manual electric welding
After welding, the welding points are polished, and then the surface is treated, including plastic spraying, transfer printing, painting and other processes; There will be the following problems during welding: , 1
Because interval welding is adopted for the welding between the inner and outer door panels, there is a certain distance between the welding points, and the welding points will also have the problem of false welding or false welding, which is difficult to ensure the strength, and the existence of welding points will damage the beauty of the door leaf 2
New materials that cannot be treated on the surface, such as paint free plate and color steel plate, cannot be used; The welding process will lead to stress and deformation of the inner and outer door panels, resulting in poor flatness; Moreover, due to manual welding, it is difficult to guarantee the welding quality, which is not conducive to the demand of large-scale production 3
Grinding, transfer printing, plastic spraying, welding and other processes are complicated, the quality is unstable, the production efficiency is low, and the waste of materials and energy is large
The generated dust and harmful objects not only pollute the environment, but also are not conducive to the health of workers Stainless steel anti-theft door http://www
