Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.

Industry standards are the basis for the development of industries and enterprises. Product technical standards are an effective guarantee for product quality. With the development and maturity of China's security industry, the national authorities are pushing for the standardization of the security industry. At present, the development of technical standards for security cable products has been incorporated into the next phase of the work plan. With the joint efforts of the government, industry and enterprises, the production and quality assurance of the security cable products will be followed in a rule-based manner. The security cable technology and application will be more reliable and professional. The field is moving fast.
Second, industrial concentration will continue to increase, leading companies occupy the mainstream market China's security industry from scratch, grow in the competition, after decades of development has formed a certain scale. With the promotion of global economic integration, there will inevitably be leading companies among the different products in the industry, and the degree of industrial concentration will continue to increase. Only industry concentration has emerged in the industry, leading companies emerged and the industry can be established to form a common development philosophy. Only from the perspective of the most basic survival considerations can companies enter the most important areas of scientific management, core technologies, and core products to promote the healthy development of the industry, so as to avoid unfair competition of low quality and low end. The chaotic competition between the large and small, miscellaneous wire and cable manufacturers, the lack of technical strength in the industry, and the size of funds will gradually end for local interests and vicious competition.
At present, leading companies in the domestic security industry have begun to show signs, and the domestic security cable market has formed a number of mainstream companies. These enterprises have expanded through continuous product extension and channels, through continuous improvement of enterprise management and team building, whether in the brand The degree of influence or the overall improvement of product quality, service specification has been increasingly accepted by the industry and users. It is believed that with the continuous improvement of industrial concentration, with the continuous expansion of the production scale of such enterprises, the productivity generated by the scale will be fully reflected in the market, and cost-effective products plus standardized services will occupy the security cable. The vast majority of market share.
Third, users continue to increase the degree of emphasis, "full line of compatibility, full service," ready to go cable products in the security system assumes important data, images and other information transmission tasks. Due to the insufficient attention of the user or the engineering firm to the purchase of cable products, problems such as the improper selection of the cable products and the quality problems that affect the entire system engineering are not uncommon, causing certain losses and negative impacts. The profound lessons of the past have led more and more users and contractors to pay close attention to the quality and correct use of cable products, and gradually changed the use of security cables. . Through the joint efforts and publicity of governments, industries, engineering companies, and production companies, the phenomenon of coexistence of high-end equipment and low-quality cables in security engineering systems is becoming less and less, and the important role of security cables in the use of systems is becoming more and more important. Everyone really realized.
Security engineering requires a perfect combination of different functional devices and the reliability of the transmission part of the product is critical to the entire security system.
Although the security cable is the main component of the transmission part, the compatibility and consistency of the transmission performance of the cable product between different model specifications and the compatibility, matching, and stability between the cable and the connected related equipment are also frequent. Ignored by industry users. The future security cable manufacturers will not only be limited to the provision of simple products in the current stage, but will also continue to extend the product chain while strengthening the service concept, providing users with a full range of compatible products, and providing the full range of products for the correct and reasonable use. The technical support and service will surely become the market development trend of the security industry.
Fourth, international cooperation and development are not to be regarded as "to be the world's security companies and to create an international brand of China's security industry", which has become the development goal and enterprise mission of outstanding enterprises in the industry. Guided by such beliefs, China's security products have extensively penetrated into many areas of the world's security industry. International cooperation between domestic enterprises and advanced developed countries has been launched in all directions. At present, several of China's most powerful security cable companies are also following the international trend of market development. Several years ago, they have started to fully formulate and launch a global development strategy. They have extensive cooperation and exchanges in technology, capital, and management. The introduction of advanced technology and management concepts of foreign companies has enabled the company's strength to be rapidly upgraded and developed. And actively go abroad to seek international markets, increase product exports, there are a large number of security cable products exported to the rest of the world.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
First, the product technology into the standardization era In order to better promote the security industry and protect the harmonious development of social life and work, security cable products must be in a safer and faster direction. China is one of the most important cable product R&D and production bases in the world. Currently, it has fire-retardant and fire-resistant, high-temperature and low-temperature resistant, low-inductance and low-noise, green environmental protection, low-smoke and halogen-free, anti-termite and rodent-proof, water and moisture proof, etc. A series of cable products with unique performance and special structure have already formed certain productivity. With the continuous improvement of social security and system security requirements, through the extensive publicity, promotion, and collaboration of governments, industries, and companies, high-performance, high-efficiency, safe and new technology cable products will surely be as safe as Western developed countries. Widely used in the system.
