Service Hotlinescrew is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. A screw is a common term for fasteners, an everyday colloquial language. Screws are indispensable industrial necessities in daily life: tiny screws used in cameras, glasses, clocks, electronics, etc.; general screws in televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws are used. Screws and nuts; transportation equipment, airplanes, trams, automobiles, etc. are used together with large and small screws. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important. Screws have been common in people's production and life for thousands of years. According to the application field, it is the largest of human beings.
At present, the screws used by people are not provided with a device that does not loosen, especially in some key parts, if the screws are loosened, it will cause heavy losses. In order to overcome the current situation, there is no device on the screw to prevent the screw from loosening, which may cause heavy losses. Guangdong Yueluo Hardware Industry Co., Ltd. The inner part will not be loose, and it will save people the trouble of maintenance and reduce the hidden danger of accidents. The solution adopted by Guangdong Yueluo Hardware Industry Co., Ltd. to solve its technical problems is to make a special screw and nut, set a stop groove on the screw, and then set a stop rod on the nut. After the screw is tightened , let the backstop rod be stuck in the backstop groove to prevent the screw from loosening. The beneficial effect of Guangdong Yueluo Hardware Industry Co., Ltd. is to ensure that the screws will not loosen during the service period, reducing the hidden danger of accidents and reducing the maintenance rate. Guangdong Yueluo Hardware Industry Co., Ltd. is further described below in conjunction with the accompanying drawings and embodiments
In the prior art, there are two ways to feed the screws of the locking screw machine, the air blowing type and the air suction type. The air suction type is suitable for relatively small screws. If the screw size is larger than M2, smaller than M5, and the length-diameter ratio is larger than 1.4, the air-blown screw machine can be selected.
Advanced bolts are the foundation of high-end machinery manufacturing, and their role can be called four ounces. On the surface, the output value of bolts only accounts for a few percent of the machinery industry. In essence, the added value it brings to key components and equipment is much higher. Over the years, after the continuous double-digit growth of Chinese bolts, the bolt industry experienced negative growth in 2012, down about 1.5% year-on-year, mainly due to insufficient market demand, especially after the bolts suffered from international anti-dumping, export sales declined. situation. [1] The competition in the bolt market is fierce, and it is moving towards brand management. In the past 10 years, the development speed of China Bolt has attracted the attention of the world, which surprised the developed countries, but also made them discover a new type of big market, and multinational companies filed in. When domestic bolt companies suddenly feel that it is so difficult to survive in the market, powerful competitors have blossomed everywhere. In today's Chinese bolt market, some small and medium-sized bolt enterprises manufacture a large number of common standard parts, which does not really bring core competitiveness to the enterprise, but is subject to changes in raw materials, labor costs and other conditions. From 4.8 to 6.8 low-strength bolts, or 8.8 to 12.9 high-strength bolts, the production technology level of Chinese bolts will be basically close to the world's advanced level, mainly ordinary standard parts and low- and medium-grade special and special-shaped bolts, with large quantities Inexpensive. It can be concluded that low-grade products flood the dominant market, a small part of high-grade, high-precision, high-strength bolts still need to be imported, and the difference between the unit price of products imported and the bid price is about 6 times or more. It can be seen that China's bolt industry is still a developing industry, big but not strong, fat but not strong, and the gap with the United States, Japan, South Korea and Taiwan, my country, and lack of technical services to solve mechanical tightening. A solid solution to realize the digitalization of products, design, manufacturing and management, and the greening of products and manufacturing processes. It is understood that the development of Chinese bolts is under increasing pressure from resources and the environment. An important way to alleviate resource constraints is to develop green manufacturing. The development of bolts will continue to be actively promoted in the direction of brand management for a period of time in the future, and promote the development of bolt projects in all directions. [1] In terms of products, mid-to-high-end products will accelerate the localization of quality research and development. The whole process from design, manufacturing, packaging, transportation, use to end-of-life treatment must consider the least waste, the lowest emissions, and the high resource utilization rate. And the environmental impact is minimized, so that the corporate benefits and social benefits are coordinated and optimized. [1] In terms of circulation, explore various value-added service models to bring value and benefits to customers. From providing a single set of bolts to providing mechanical fastening solutions, customized services, remote monitoring, etc., the proportion of services in the sales revenue of bolt manufacturers will gradually increase. [1] Corporate restructuring is a trend, and strategic alliances seek development. At present, the low industrial concentration of China's bolt enterprises has seriously restricted the improvement of China's bolt competitiveness. The market opening over the years has not brought the core technology. In view of the above situation, the reorganization and strategic alliance between enterprises is a major trend. China's bolt industry must conform to this trend and trend, strengthen strategic cooperation between enterprises, and improve the overall competitiveness of China's bolts. China's growth in the field of bolt core technology lacks breakthroughs. At the same time, the living space of low-end products is getting smaller and smaller, and foreign capital through localized enterprises also has considerable cost advantages, coupled with the advantages of technology brands, and began to enter the market space of the original independent brands.
Embedding of fasteners, especially screws. The main point of the structure is that it includes an annular base, one at the base and a plurality of cylindrical tubes on the base, and the cylindrical tubes and the cylindrical tubes on the base are connected by ribs. Cylindrical tubes are used as fixing holes and fastener pre-embedded holes respectively. The product is fixed on the formwork that needs to use screw points through the fixing holes. After the concrete is poured into the floor, the embedded screw parts are pre-embedded, and the floor has embedded screw holes for hanging the installation objects with screws. . Avoid future re-drilling damage to the wall and floor. Guangdong Yueluo Hardware Industry Co., Ltd. has a simple and scientific structure, easy pre-embedding, strong tensile strength and firmness.
