Methods of production of components for building fasteners - Method of production of components for construction fasteners
The production method of the construction fastener includes the production method of the hot pressing process of the cover plate and the middle part.The production method of the cover plate is: after the steel plate is made into a blank by the punching machine, the blank is heated out of the shape of the cover sheet after the workpiece is cooled Into the punching punch punch out of the bolt hole and then put the workpiece on the mouth of the mouth on the outside of the opening hole on both sides of the up a convex after the formation of the middle of the production method: the steel plate after the punching machine in the cross-line longitudinal installation The position of the bolt is out of the elongated hole and the workpiece is heated in accordance with the mold to punch out the shape of the middle part; after cooling, the workpiece is placed on the inclined table to fine-mold each hole. The invention has the advantages that the fastener is produced by Hot stamping process The process increases the toughness of the fastener is not easy to change the fastener after hot stamping increased R arc curvature of the bayonet connection surface area increases so that the contact area increases the friction to make the construction fastener more secure reliable.
Construction fasteners are reused products, after each use of the acceptance and retirement work to do enough, for many years the use of serious corrosion of steel pipe, fasteners are still in the construction site to continue to use, the use of substandard fastener products caused by the relevant scaffolding With the provisions of the specification, the construction unit according to the qualified fastener product carrying capacity of the scaffolding erection program is equal to meaningless, to the construction management and construction safety caused by a lot of uncertain factors. Fastener and wedge plate, fastener body with The utility model has the characteristics of quick and easy assembly and disassembly of the utility model, and the fastener itself has the following features: (1) the use of the wedge fastening principle, Simple structure, low production cost characteristics.
