Service HotlineThe global economy continues to slump and overseas export trade is sluggish. Many fastener companies at home and abroad are facing severe tests. Accelerating economic transformation and structural upgrading is imminent, and developing overseas markets is undoubtedly an important way out for the development of the current fastener industry. From the fourth quarter of 2011 to the first half of 2012, affected by the objective environment, the development speed of the fastener industry may slow down, but from the third quarter of 2012, with the policy in place, the convening of the 18th National Congress of The upcoming series of development policies, etc., can promote the further development of the industry. And we must insist on innovation and adjustment and transformation, we must continue to rely closely on key industries such as automobiles, new energy, aerospace, shipbuilding, urban transportation, IT, electronic appliances, construction, etc., accelerate the optimization and upgrading of fastener products, and promote fasteners. The whole industry develops healthily and steadily. The global fastener market size exceeds 50 billion US dollars, and China's total fastener production in 2012 is also expected to reach about 6.8 million tons. However, compared with the manufacturing powerhouses such as the United States and Japan, there is still a big gap in my country's fastener industry.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a flat gasket that improves the lubrication performance of the contact surface and reduces the friction of the contact surface. Yueluo is implemented through the following technical solutions: a flat gasket with straight upper and lower end faces, characterized in that: the upper and lower end faces are dotted with pits, the pits are spherical pits, and the pit diameter is 2-3mm , the pit depth is between 0.5-lmm. The bottoms of some of the pits are provided with through holes penetrating the upper and lower end faces, and the diameter of the through holes is not greater than 0.5mm. The flat gaskets provided by Yueluo have pits with reasonable design parameters on the upper and lower end faces of the flat gaskets. The pits can store oil, so the lubrication of the contact surfaces of the gaskets can be well improved. It can effectively reduce the friction of the contact surface of the gasket and reduce the failure rate; in addition, the design of the through hole enables a smooth oil passage between the upper and lower end faces of the gasket, ensuring that the upper and lower end faces can be well lubricated.
Stainless steel rivet nuts are used on rail passenger cars, highway passenger cars, and ship parking. The main function is the non-structural bearing bolt connection. The main advantage of stainless steel rivet nuts is that there is no operating space on the back of the substrate, and the quality is extremely light. Today, the editor will talk about the selection principles of stainless steel rivet nuts and their uses: 1. The mechanical properties of stainless steel rivet nut materials, especially the strength requirements; Corrosion resistance requirements of materials;
Rivets for blind holes, including a cap head and a hole post, the cap head is fixed on one end face of the hole post, a tip is formed on the other end face of the hole post, and the end of the hole post close to the cap head is along its side circumference An annular groove is formed concave inward. After the hole column of the blind hole is placed in the blind hole position of the metal piece, the tip of the end face of the hole column is squeezed into the metal material under the end face of the hole column under the action of external force, and the metal material on the side of the hole column is also affected by the hole. The extrusion of the side of the column makes part of the metal material completely squeezed into the annular groove, so that the annular groove is filled more firmly, and at the same time, the tip is squeezed into the metal material, which can double-position the rivet. Therefore, the self-riveting of the rivet is realized. The rivet also has the advantages of simple structure, simple and fast installation, and no cracking caused by impact and other undesirable phenomena.
Spring mattresses and spring seat cushions are modern and commonly used furniture products with better performance, and their cushion cores are composed of springs. It makes full use of the advantages of good spring elasticity, good support, strong air permeability and durability. The traditional spring pad is a spring with a thicker wire diameter, which is connected and fixed by steel wires, and has high hardness. Most of the elders of the older generation often use linked spring beds, but if they sleep in a fixed position for a long time or are accustomed to sitting on the side and corners of the bed, or flip the mattress irregularly, it is easy to cause depression and elastic fatigue.
