Service HotlineThe lifting ring nut refers to the part that the nut and the bolt or the screw are screwed together for fastening, and it is an original part that all production machinery must use. The lifting ring nut is a commonly used fixing pendant in engineering. There is a thread under the nut, which can be drilled according to its different specifications and fixed by the screw.
In the household and industry, when installing furniture, home appliances, electrical appliances, equipment and other objects, the objects are uneven or uneven due to the uneven bottom of the object, or because the placement surface or installation surface is uneven, or because the two surfaces are different and do not fit together. stable, produce vibration, shaking or sliding, affecting the use effect and service life. Sometimes two items need to be placed next to each other, but their surfaces cannot be in direct contact, otherwise the surfaces will be damaged. For these two cases, the common solution is to install gaskets. There are two types of gaskets: wedge and flat. The wedge-shaped gasket adjusts the actual thickness by adjusting the length of the insertion gap, but the contact surface and load-bearing surface of this method are small, and due to its wedge-shaped structure, the gasket may withdraw after being stressed for a long time. Flat gaskets are generally made from local materials, using waste paper, plastic, rubber, metal and other materials to form the required thickness by folding or stacking. Such gaskets are often not quickly assembled to the exact desired thickness, are not aesthetically pleasing, and are not reusable. The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a product that can keep furniture, home appliances, equipment, electrical appliances and other objects horizontal, vertical or stable, prevent them from vibrating, shaking or sliding, and can provide appropriate thickness and beautiful appearance. gasket. The purpose of Yueluo is to realize a gasket that can be combined at will. The sheet 1 is provided with small holes 3 , and the connecting device 2 connects a plurality of sheets 1 together through the small holes 3 . The connecting device 2 is a rivet or a screw. The material of the sheet 1 can be plastic, metal, paper card or rubber. The gaskets provided by Yueluo can be combined at will. Multiple sheets are connected together by rivets or screws. By opening or closing the sheets, or dismantling the screws, the sheets are reassembled to obtain a combination of gaskets with different thicknesses and elasticity. The space between the installation object and the installation surface to keep the object horizontal, vertical or stable and prevent it from vibrating, shaking or sliding.
Comparing the physical properties of stainless steel and carbon steel, the density of carbon steel is slightly higher than that of ferritic and martensitic stainless steel, but slightly lower than that of austenitic stainless steel; the resistivity is based on carbon steel, ferritic, martensitic and The order of austenitic stainless steel is increasing; the order of linear expansion coefficient is similar, austenitic stainless steel is the highest and carbon steel is the smallest; carbon steel, ferritic and martensitic stainless steel are magnetic, austenitic stainless steel is non-magnetic, But its cold work hardening will generate magnetism when it is transformed into intensite, and heat treatment method can be used to eliminate this martensitic structure and restore its non-magnetic properties. Compared with carbon steel, austenitic stainless steel has the following characteristics: 1) High electronegative rate, which is about 5 times that of carbon steel. 2) The large coefficient of linear expansion is 40% larger than that of carbon steel, and with the increase of temperature, the value of the coefficient of linear expansion of stainless steel screws increases accordingly. 3) Low thermal conductivity, about 1/3 of carbon steel.
The specifications of copper inserts are: internal thread specification 1/4-20, outer diameter 10mm, length 15mm mesh pattern copper nut, drawn from flower pull raw materials. The automatic lathe completes at one time: stocking → chamfering → drilling → hooking chamfering → tapping. Stable size, no eccentric internal thread. Material selection: copper C3604, Rohs PASS. The copper nut is used in injection molded parts.
Stainless steel screws, as the name suggests, must be made of stainless steel screw wire, and then screw the screw thread. Many of the properties of stainless steel screws are related to stainless steel. Taking into account the properties and organization of stainless steel, understand the properties of stainless steel materials and other aspects. Therefore, it is understood that stainless steel has good mechanical properties such as anti-rust, anti-corrosion, high temperature resistance, etc., then stainless steel screws also have these good mechanical properties. With the increasing quality of stainless steel materials. The mechanical properties of stainless steel screws produced by the screw industry are getting better and better. Anti-rust, anti-corrosion ability, and high temperature and high pressure are getting stronger and stronger.
