Description

Technical Field

[0001] The utility model relates to the technical field of steel door leaf hinge lining assembly, in particular to a non-welding riveted fixed hinge lining. Background Art

[0002] In the manufacturing process of traditional steel door leaf components, welding technology plays an important role, but the welding quality requirements are high, and the proportion of automated and mechanized welding is low, while manual welding accounts for a high proportion. This method is inefficient and prone to serious pollution. In addition, there are many welding-related standards, and welders and welding engineers must undergo rigorous training and examinations before they can take up their posts, so skilled welder resources are relatively scarce.

[0003] The hazards in the welding process are mainly reflected in the following three aspects:

[0004] 1. Hazards of metal fume: The composition of welding fume varies depending on the type of welding rod. The welding rod is mainly composed of welding core and coating. In addition to a large amount of iron, the welding core also includes carbon, manganese, silicon, chromium, nickel, sulfur and phosphorus. The materials in the coating are mainly composed of marble, fluorite, rutile, soda ash, water glass, ferromanganese, etc. During the welding process, arc discharge generates high temperatures of 4000℃ to 6000℃, causing the welding rod and weldment to melt, and at the same time generating a large amount of smoke. The smoke is mainly composed of iron oxide, manganese oxide, silicon dioxide, silicate, etc., which permeates the working environment and is easily inhaled into the lungs. Long-term inhalation of such smoke can lead to fibrotic lesions of lung tissue, namely welder's pneumoconiosis, and may be accompanied by complications such as manganese poisoning, poisoning and metal fume fever.

[0005] 2. Hazards of toxic gases: Under the high temperature and strong ultraviolet rays generated by the welding arc, a large amount of toxic gases, such as carbon monoxide and nitrogen oxides, will be produced around the arc area.

[0006] 3. Hazards of arc radiation: Arc light generated by welding mainly includes infrared, visible light and ultraviolet light. Among them, ultraviolet light is harmful to the human body through photochemical action, damaging the eyes and exposed skin, and causing keratoconjunctivitis (photoelectric eye inflammation and cutaneous erythema).

[0007] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a weldless riveted fixed hinge lining. Utility Model Content

[0008] The utility model aims to provide a non-welding riveted fixed hinge lining plate to solve the problems raised in the above background technology.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is a weld-free riveted fixed hinge lining. This solution replaces the welding parts that originally required electric welding by a welding machine and were operated by skilled workers with rivet-free parts that can be directly connected with screws, thereby replacing the traditional welding process with the steel door riveting process, thereby reducing the technical operation level requirements of production workers. In addition, omitting the door leaf welding process helps to save material usage. At the same time, this solution can also improve the overall surface effect of the product and increase its aesthetics. The connection process is highly automated, supports single-point or multi-point simultaneous connection, and can perform non-destructive connection strength detection and automatic monitoring of the entire process, thereby improving production efficiency.
