The fastener production method includes a cover plate and a middle portion of the hot press process production method. The production method of the cover plate is as follows: after the blank is formed from the steel plate through the punching machine, the blank is heated, and the shape of the cover plate is punched out by the punching machine. After the workpiece is cooled, the punching machine punches out the bolt holes, and then the workpiece is placed on the crucible. On the mouthpiece, a bulge is formed on each of the outer sides of the opening hole. The production method of the middle part is as follows: after the steel plate passes through the blank of the punching machine, a long hole is punched at the position of the cross wire longitudinal mounting bolt, the workpiece is heated, the shape of the middle part is punched according to the die, and the workpiece is placed on the inclined table after cooling Each hole is finely punched and shaped. The advantage of the invention lies in that the production method of the fastener is a hot stamping process. This process increases the toughness of the fastener and is not easy to be deformed. After the fastener is hot stamped, the curvature of the R arc is increased, so that the area of the bayonet connection surface is increased. Large, so that the contact area increases, increase friction, so that building fasteners more secure and reliable.
