Hexagonal bolt is a widely used mechanical connection, and its structure includes head, screw and thread. This bolt adopts hexagonal head design, which is very convenient to use on large hexagonal parts. Its use is not limited to simple connection function, but also provides unique value in many aspects.   First of all, hexagonal bolts are used as connecting bridges in mechanical structures. Whether it is large equipment or precision equipment, bolts are essential connecting elements. By rotating the threaded part of the bolt, multiple parts can be tightly connected to form a stable and complete working unit.   Secondly, hexagonal bolts have a better ability to bear loads. During the operation of mechanical equipment, the traction and shear forces on the bolts are very large. However, due to the compact design and reasonable structure of hexagonal bolts, these forces can be effectively dispersed to ensure the stability and durability of the connection.   In addition, hexagonal bolts also have anti-loosening properties. In a high-intensity working environment, loosening between bolts and connecting parts is a safety hazard. The unique thread design of hexagonal bolts provides additional locking force during the connection process, which can effectively prevent loosening and ensure the reliability of the entire mechanical system.   Finally, hexagonal bolts are also useful for aesthetic design. In fields with high aesthetic requirements such as home decoration and automotive exterior design, hexagonal bolts become unique decorative elements with their simple and elegant appearance. Even when exposed, they can add bright colors to the overall design and enhance the overall beauty.

Bolts are screws with a particularly large diameter, but some have no head. For example, stud bolts. The most commonly used stud bolt form has threads at both ends and one thread in the middle. The center screw can be thick or thin. The fixed link function used to connect machines is commonly used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, crane towers, large-span steel structures, large buildings, etc. The most typical use: anchor bolts, or places similar to anchor bolts, thicker connections, used when ordinary bolts cannot be achieved.   Main purpose：   1.The main body is used for large equipment and must be equipped with accessories such as sight glasses, mechanical seals, and reduction frames. In this case, a stud bolt is used, one end of which is screwed into the main body, and the other end is installed with accessories and nuts. Frequent disassembly of accessories causes thread wear or damage, so it is very convenient to replace with a stud bolt.   2. When the thickness of the connecting body is large and the length of the bolt is very long, double-headed bolts will be used.

3. Questions 3.1 Bottleneck problem of large-scale application of industrial robots Facing the bottleneck problem of large-scale application of industrial robots, the application of industrial robots is generally based on non-standard integrated applications, and the payback period of intelligent factory transformation is generally long, basically the payback period of 5 years can be accepted by advanced manufacturing enterprises, but a large number of small and medium-sized enterprises can only accept the payback period of 2 to 3 years. The application of industrial robots needs to overcome the cost problems of robot selection, special mechanism development, robot programming testing and application services. Application switching is costly, and low individual application usage results in high R&D amortization. In addition, the industrial robot system's incomplete replacement of labor and high construction and maintenance costs lead to market fragmentation and high operation and maintenance costs. The application problems to be solved are as follows: 1) Core controller and application software research and development issues, industrial robot control includes application and execution, is the core carrier of industrial robot application expansion and application level. How to form the application ecology of industrial robots, break the threshold of application development, and accelerate the replication of industrial robot application software are the main problems facing the application expansion of industrial robots. 2) Standardization problem driven by industrial robots, non-standard industrial robots have many hardware types, and various extended interface standards are complex. How to form a standard interface access model and develop application software of industrial robots using socialized and market-oriented models is a problem faced by the rapid application of industrial robots. 3) The modularization problem of special aircraft and parts of industrial robots, especially the secondary application development ability of hardware and software such as controllers, reducers, robot arms, vision modules, and systematic interface modules, is the main obstacle to the rapid formation of application forms of industrial robots. 4) How to carry out rapid design of industrial robot applications, such as using low-code tools, self-learning teaching, etc., to form a standard way of rapid development of industrial robots. 5) How to improve the service capability of the industrial robot industry, after the delivery of industrial robot applications, through remote online means, low-cost industrial robot services, and the formation of rapid training methods, reduce the threshold of localized services, which is also the core problem that hinders the widespread use of industrial robots. China's industrial robot field has long been stuck in a state of neck, but China's fastener enterprises have the world's largest potential market, especially with nuclear power, wind power, automobiles, rail transit EMU, aerospace supporting many of the largest production and application markets, enough application opportunities to give birth to industrial robot leading enterprises in many fields. Thus, the rapid catch-up in the core technology and application technology, so that fastener enterprises from a labor-intensive development stage into the development stage of the widespread application of industrial robots, across the current labor and other costs caused by the development bottleneck. 3.2 Shortage of intelligent manufacturing system engineers Intelligent manufacturing is the deep integration of a new generation of information technology and advanced manufacturing, which runs through all aspects of manufacturing activities such as design, production, management and service. In addition to professional talents familiar with digitalization, networking and intelligent technology, intelligent manufacturing is in urgent need of cross-professional talents with mechanical and electrical, industrial software, control, computer and industrial engineering and other foundations, as well as cross-disciplinary system level talents. At present, intelligent manufacturing system engineers are in short supply. As the main source of intelligent manufacturing talents on the supply side, most of the talents trained in colleges and universities are mechanical and electrical and automation, and the disciplines are seriously divided, and there are shortcomings in the new generation of information technology such as network communication and industrial software. The new generation of information technology professionals have little knowledge and experience in electromechanical and automation. Although some undergraduate colleges and universities have set up new engineering majors such as intelligent manufacturing engineering technology and robot engineering, there is a large gap between the talent training goals of colleges and universities and the needs of industrial development, and the quality of talent training can not meet the actual needs of the development of intelligent manufacturing. System-level talent is still scarce in the enterprise. With the acceleration of the integration of new generation information technologies such as artificial intelligence, big data, industrial Internet and 5G with automotive manufacturing technology, there is an increasing demand for system-level talents who are familiar with both new generation information technology and industry technology. The training cycle of such system-level engineering and technical personnel is long, and the training is difficult, and enterprises are faced with the dilemma that they cannot recruit and stay. The shortage of system-level talents restricts the rapid development of intelligent manufacturing in the industry, and the solution of the problem is imminent.

1. Status quo At present, the global digital wave is in the ascendant, and the deep integration of a new generation of intelligent technology and manufacturing industry is profoundly changing the development model of manufacturing industry. The development of intelligent manufacturing has become the key to the global manufacturing industry to reconstruct competitive advantages, shape industrial characteristics, and transform development concepts, and is also an important transformation strategy for China's manufacturing industry to achieve high-quality development. The report of the 20th National Congress of the Party proposed to promote the high-end, intelligent and green development of the manufacturing industry, which pointed out the way forward for the high-quality development of the manufacturing industry. The industrial Internet, supported by digital technology, promotes the efficient flow of production factors such as data and provides more support for enterprises to carry out product innovation, business model innovation and technological innovation. In line with the general trend of economic and social digital transformation, promoting the scientific and efficient digital transformation of enterprises in traditional industries is crucial to stimulate the vitality of business entities, shape new competitive advantages, and achieve high-quality development. As a branch of the manufacturing industry, in recent years, fastener companies are also accelerating the development of intelligent manufacturing, and the number of shortlisted intelligent manufacturing demonstration factories has nearly 20. Accelerate the integrated development of new generation information technologies such as artificial intelligence, 5G, industrial Internet, Internet of Things, blockchain, cloud computing, big data, and manufacturing: implement the "5G+ Industrial Internet" innovation action, and promote the construction of smart supply chain networks, smart workshops, and smart factories; Explore intelligent production planning and production process coordination; Support the construction of "machine replacement" in various industries and demonstration projects of intelligent manufacturing model factories (workshops). Fastener enterprises through intelligent transformation to promote enterprise machine replacement, production line change, product replacement, production efficiency increased by about 20% on average, product upgrade research and development cycle shortened by about 31% on average, product defect rate reduced by about 20% on average. Develop and transform intelligent equipment technology, and develop specialized intelligent equipment. In the composite CNC machine tools, industrial robots and integrated applications, intelligent special equipment and other aspects of the development of a number of advanced applicable products, to promote the realization of replacing imported products. Intelligent manufacturing, as the main direction of promoting the construction of a manufacturing power, has been highly valued in all sectors of government, industry, university and research, and has formed a high degree of consensus and actively promoted the implementation of the implementation. Governments at all levels have issued a series of intelligent manufacturing development plans, intelligent manufacturing engineering implementation guidelines, action plans, and special actions, and launched a number of smart manufacturing-related pilot demonstration projects, which have achieved fruitful results. Although fastener enterprises have established the main direction of intelligent manufacturing and achieved remarkable results in promoting the implementation, there are still many outstanding problems that seriously restrict the development of intelligent manufacturing. There are many bottlenecks at the technical level, intelligent manufacturing talent is very short, the enterprise foundation is weak and very different, regional development is very unbalanced, the main body of the implementation of intelligent manufacturing, the majority of enterprises have a strong demand for intelligent upgrading, but there are many puzzles and problems. GAF2023 Global Screw Jun Technology Conference and Expo, with the trend also set up the "high-end fastener intelligent manufacturing and smart factory, cost reduction and efficiency Conference" to carry out a thematic discussion. However, key fastener enterprises have generally completed digital and network transformation in the main areas, introduced digital tools and information software, and built digital factories, and data has gradually become an important production factor of enterprises. 2. Difficulties At present, the intelligent manufacturing data analysis is mainly to use a certain type of data in the information system, due to the lack of tools and methods to solve the problem of industrial big data clutter, and the data generated by different production links have different characteristics, so how to solve the common data problems and characteristics of intelligent manufacturing data problems? How to effectively use these data to achieve intelligent manufacturing human-machine collaboration scenarios? It is a key direction of cross-research between data science and mechanical engineering. (1) Fastener enterprise complex heterogeneous big data processing and standardization With the popularization and application of sensors and 5G networks, enterprise production data, operation data, equipment data, quality data and material and energy consumption data have been collected online, and industrial data has shown massive explosive growth. However, due to the limited modeling and performance capabilities of existing technologies, the processing and identification accuracy of complex and heterogeneous data cannot realize the value creation of industrial data. By introducing data mining and machine learning methods, establishing a universal standardized model and unifying data standards, the characteristics of industrial data can be better identified and the problems of large, scattered and large industrial data can be solved. (2) Intelligent scheduling for the whole process of data flow With the continuous increase of digital equipment in the production line, the orderly flow of data generated by different equipment constitutes the whole process of manufacturing data flow, and through the integration of data flow and production process, the enterprise scheduling has undergone major changes. Carry out in-depth intelligent data collection and mining on the relevant data information of planning and scheduling, material balance, predictive maintenance and other dimensions involved in the production process of the enterprise, and carry out intelligent scheduling algorithm modeling under different business scenarios such as just-in-time production and hybrid production involved in the production planning and scheduling process. It can better analyze various production business indicators of enterprises from different angles, and find rules, early warning anomalies, improve emergency response capabilities, and ultimately achieve the purpose of monitoring production activities, providing production efficiency, and supporting the production balance of enterprises. (3) Human-computer interaction and integration of intelligent manufacturing With the rapid development of three-dimensional processing capabilities of intelligent terminals in fastener companies and the emergence of low-cost sensing and display components, the virtual world and the physical world can be connected through intelligent terminals. However, due to the characteristics of big data in the industrial field, the collection and identification accuracy of human-computer interaction scenarios is low, and the efficiency and interaction degree of human-computer interaction cannot meet the needs of fastener enterprise scenarios. All aspects of manufacturing are independent of each other, and the cooperation is weak, which leads to the poor versatility of intelligent equipment. Through the establishment of human-machine interaction scenarios driven by data flow, the virtual information technology and the real economy can be comprehensively, deeply and intelligently coupled in the whole process of production and manufacturing and in various fields. Through real-time update and accurate control of data information, integrated optimization modeling research of design, process, manufacturing, management and logistics can be carried out. It can improve the precision of manufacturing execution and process control, and solve the common problems of human-computer interaction and integration. To this end, combined with the data DAAS, data transmission, perception interaction and other resources of fastener enterprises, from the five dimensions of R & D design, production and manufacturing, industrial assembly, industrial inspection and remote operation and maintenance, establish state perception, virtual reality presentation, man-machine collaboration and accurate execution of enterprise business management, and realize the automatic flow of data, perception analysis and decision execution in a visual presentation way. The realization of the virtual and real integration scenario of industrial data, so as to continuously drive, improve and enhance the production process, reduce the uncertainty of complex production systems, and promote the spiral rise of the business management level of various dimensions of the production process, has practical significance for accelerating the realization of intelligent manufacturing to support the development of the digital economy. we also supply other types fastener products, like wedge anchor, hex bolt, hex nut, tapping screw, thread rod and so on.
