Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a low-carbon steel rivet nut fastener, which can be easily fixed on a thin wall without welding, easy to operate, firm riveted, and suitable for single-sided riveting.
Surface treatment process of screws 1. Types of surface treatment: Surface treatment is the process of forming a covering layer on the surface of the workpiece by a certain method. The purpose is to give the surface of the product a beautiful and anti-corrosion effect. The following methods are as follows: 1. Electroplating: Immerse the part to be electroplated in an aqueous solution containing the metal compound to be deposited, and pass the current through the plating solution to precipitate and deposit the electroplated metal on the part. Generally, electroplating includes galvanized, copper, nickel, chromium, copper-nickel alloy, etc., and sometimes blackening (blue), phosphating, etc. are also included. 2. Hot-dip galvanizing: It is done by immersing the carbon steel parts in a zinc-melting bath with a temperature of about 510°C. The result is that the iron-zinc alloy on the surface of the steel gradually becomes passive zinc on the outer surface of the product. Hot dip aluminizing is a similar process. 3. Mechanical plating: The surface of the product is impacted by the particles of the plated metal, and the coating is cold welded to the surface of the product.
Guangdong Yueluo Hardware Industry Co., Ltd. relates to a square nut fastener for cable bridge installation, which is characterized in that it includes an upper plate body and a U-shaped jacket, and the upper plate body is provided with a downwardly protruding connecting cylinder, The two side plates of the U-shaped jacket are connected to the connecting cylinder, and the center line of the two side plates is located on the center line in the length direction of the upper plate body; the bottom of the U-shaped jacket is a wave-shaped elastic plate, which is a wave-shaped elastic plate It is fixedly connected on the two side plates, and the space enclosed by the two side plates of the U-shaped jacket, the wave-shaped elastic plate and the bottom of the connecting cylinder is the installation position of the square nut. Guangdong Yueluo Hardware Industry Co., Ltd. has a simple and reasonable structure, and is extremely convenient and flexible to operate; it does not occupy the bottom space of the C-shaped steel after installation, which increases the variety of installation, and can be applied to square nuts of different thicknesses, and the installation is firm.
The commonly used tools for fixing screws on the surface of the workpiece are electric screwdrivers and manual screwdrivers. Both of these screwdrivers manually attach the screws to the bits of the electric screwdriver or manual screwdriver, and then fix the screws on the surface of the workpiece. The screwdriver is inefficient in fixing the screw, and cannot accurately locate the screw fixing point.
The traditional gasket is a single-piece gasket that works independently. This gasket mainly relies on friction to achieve the anti-loosening effect. The new washer is composed of two pieces. Its unique embedded structure changes the way that the traditional washer mainly achieves anti-loosening through friction. Instead, it adopts the most advanced anti-loosening technology in the world and uses the tension between the two gaskets to achieve. The dual effect of anti-loosening and tightening.
