Service HotlineWhen fixing the centrifugal fan, since the gaskets, washers and nuts are separate parts, many parts are used in the whole process, and it is easy to miss the installation of parts; The volume of the parts is relatively small, and it is not easy to remove them when they are transferred into the air conditioner through the gap of the centrifugal fan blades, resulting in foreign bodies in the machine.
The composition and proportion of this high-performance stainless steel screw thread are: 0.08%-0.15% C; 0.01%-0.60% Si; 0.02%-0.60% Mn; 0.01%-0.03% P; 0.002%- 0.03% S; 12%-14% Cr; 0.8%-1.5% Mo and the rest is Fe. The preparation method includes the following steps: smelting molten steel according to chemical composition requirements; hot rolling; annealing and pickling to obtain a stainless steel plate blank; coating and drying; cold drawing; cleaning and drying with a neutral activator; quenching; tempering ; coated and dried; drawn into stainless steel thread. This high-performance stainless steel screw line is energy-saving and environmentally friendly, with high corrosion resistance, high elasticity and high toughness. The preparation method and process are advanced and simple, and the production cost is low.
The purpose of Yueluo is to provide a stamping process for screws. Before stamping, a sticky protective layer is coated on the pressure surface of the screw blank. The sticky protective layer can play a buffering role during stamping and prevent the screw head from being damaged. In order to achieve the above purpose, the technical solution of Yueluo is to design a screw stamping process, which uses a stamping die to stamp the screw blank and punch out the screw head; and before stamping, the pressure surface of the screw blank is coated with adhesive protection. layer.
In our life, there are many solid wood furniture. The parts of these furniture are positioned and connected by connecting parts such as screws or nails, so the surface of the furniture will leave marks of screws or nails, or even some cracks, so that the surface of the furniture will not be damaged. Flat, particularly unsightly.
At present, it has become very common to use automated tools to hit screws.
