The invention discloses an aluminum welding nail, a mold for producing the aluminum welding nail and a method for producing the aluminum welding nail. The aluminum welding nail comprises a welding bolt; a welding table is arranged at one end of the welding bolt; an electric conducting convex tip is arranged in the center of the bottom surface of the welding table; a fixed pressing disc is arranged at the top of the welding table; and the welding table and the fixed pressing disc are integrally molded. The mold for producing the aluminum welding nail comprises a first mold and a second mold independently arranged. The method for producing the aluminum welding nail comprises such processes as primary punching and secondary punching. As the welding table and the fixed pressing disc are set as the integral molding structure, (1) a thread has no need to be machined on the surface of the welding bolt, (2) a screw cap has no need to be machined for matching, (3) a procedure of tightening the screw cap is not needed after welding, and (4) the possibility of generating looseness of the screw cap after fixation is prevented. The mold for producing the aluminum welding nail and the method for producing the aluminum welding nail reduce the production cost of the welding nail, and improve the aluminum plate fixing safety.
Description
technical field [0001] The present invention relates to a welding stud, specifically an aluminum welding stud. Background technique [0002] Building curtain walls are often decorated with aluminum plates. Aluminum plates maintain their own characteristics and surface flatness, and aluminum welding nails are used to fix reinforcing ribs to maintain them. Aluminum welding studs include threaded welding studs and nuts, and the existing technical problems are as follows: [0003] 1. After the nut is fixed, it will loosen after a long time; [0004] 2. The nut is fixed. After welding and fixing, the nut needs to be tightened, and the installation is time-consuming and laborious. [0005] 3. When fixing the nut, it is easy to cause the welding stud to open and fall off. [0006] 4. Process the welding stud. The welding stud needs to process the thread matched with the nut, and also process the nut with the anti-loosening friction surface, and the processing cost is high. Con...
