The production method of the 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 as follows: after the steel plate is produced into a blank by a punching machine, the blank is heated, and the shape of the cover plate is punched out with a punching machine. On the mouth machine, a protrusion is formed on both sides of the outer side of the opening hole.
Excellent fracture resistance – advanced all-steel cold-pressed structure, all-steel cold-pressed forming, strength and toughness exceed national and international standards, completely eliminate the accident hidden danger of scaffold collapse caused by old cast iron fasteners due to fastener fracture.
Specializing in the production of fasteners, summarizing years of production experience, and escorting your quotation!
-Excellent anti-slip – large bonding area
It ensures that the steel pipe and the fastener are in a state of surface bonding, and the bonding area is the largest. It overcomes the point or line bonding between the old fastener and the steel pipe, and eliminates the hidden danger of the steel pipe slipping, thereby ensuring and improving the overall mechanical properties of the scaffold. safety performance.
-Anti-strength – a new type of connection
It is ensured that in the case of steel pipe shifting, the fastener can always be fixed vertically and correctly and firmly, eliminating the possibility of steel pipe slipping.
-Strong rust resistance – passivation treatment
The whole piece has been passivated and galvanized for double anti-corrosion treatment, its anti-corrosion ability is greatly improved, and its service life is far longer than that of old fasteners.
-Fast and light – structural optimization
The fastener is light and beautiful, the loading and unloading speed is increased, and the labor intensity is reduced.
