Component production method for building fasteners
The production method of the construction fastener comprises a cover plate and a hot pressing process production method in the middle part. The production method of the cover plate is: after the steel plate is punched out into a blank by the punching machine, the blank is heated by a punching machine and punched out of the shape of the cover plate, and the workpiece is cooled. The punching punching machine punches out the bolt hole and then places the workpiece on the boring machine to form a protrusion on each of the outer sides of the opening hole. The middle part is produced by: the steel plate is longitudinally installed on the crosshair after passing through the blank of the punching machine The bolt position is punched out of the elongated hole to heat the workpiece according to the shape of the middle portion of the die; after cooling, the workpiece is placed on the inclined table to perform precision punching on each hole. The advantage of the present invention is that the fastener is produced by Hot stamping process This process increases the toughness of the fasteners. It is not easy to deform. After the hot stamping, the fasteners add R arc curvature to increase the area of ​​the bayonet joint surface, which increases the contact area and increases the friction to make the building fasteners safer. reliable.
The construction fasteners are reusable products, and the acceptance and scrapping work after each use is not enough. For many years, the steel pipes and fasteners with severe corrosion are still used in the construction site, and the unqualified fastener products are used according to the national related scaffolding. According to the provisions of the specification, the scaffolding erection scheme prepared by the construction unit according to the bearing capacity of the qualified fastener products is meaningless, which causes many uncertain factors for the construction management and construction safety. The fastener body and the wedge-shaped inserting plate are provided on the fastener body. The plug-in slot is inserted into the slot of the plug-in board. The utility model has the advantages that the wedge fastening principle is adopted, so that the utility model has the characteristics of quick and convenient assembly and disassembly when fastening the pipe fitting, and the fastener itself has Simple structure and low production cost.
