In recent years, with the rise in the prices of labor factors such as labor and energy, the production costs of machine tool industry companies are also rising. The problem is not limited to this, because the machine tool industry is a technology and skill-intensive industry, the skills and science of labor. Literacy is very important for enterprises. Therefore, the recruitment of machine tools is harder than other industries. Moreover, the decline in birth rate has also caused the demographic dividend of our country to gradually disappear. The arrival of “Lewis Turning Point†indicates the future manufacturing. Semi-automated, automated production in the industry and throughout the industry is an irreversible trend. Whether it is Shanghai International Machine Tool Show or other large-scale international machine tool exhibitions, this trend is hinted to some extent. This trend is more obvious from the recent Shanghai International Machine Tool Show. The number of exhibitors and exhibits about industrial robots seen at the exhibition site is increasing. For example, the famous ABB company, KUKA and Shanghai FANUC Robotics Co., Ltd., the flow of people in front of the booth is proof. FANUC's line of automotive production lines is popular with the market: it is used in "body factory flexible automation systems" such as painting robots (RobotP-250iA), arc welding robots (RobotM-20iA), spot welding robots, handling robots, etc. Wait. Liu Dawei, sales manager of Metal Processing Division of FANUC, said that the company's sales this year have increased by a large margin compared with last year, especially in the automotive users and machine tool industry. KUKA is very focused on its range of robotic applications in the automotive industry, whether it is arc welding, spot welding, laser welding and cutting, gluing, bending, edging, assembly, stamping, etc.; In the field of metal cutting, KUKA's handling, loading and unloading, deburring and other robots have a modular structure, and the extension arm can be added to maximize the working space. In terms of CNC machine tools and metal processing, automation is not only the pursuit of high precision and high efficiency in the user industry, but also an inevitable requirement for the integration of industrialization and informationization. At each Shanghai International Machine Tool Show, exhibits from various pavilions show the result of cross-infiltration of mechanical and electronic technologies and information technology. The 2MNKA9820 nanometer precision micro CNC grinding machine of the above-mentioned sea machine tool factory Co., Ltd. adopts a series of advanced technologies combining hydrostatic guide rail, ultra-precision linear motor, gas static pressure spindle and built-in electric spindle, which can achieve Ultra-high repeatability of 50nm and extremely high rotation accuracy for nanometer-level machining accuracy. Obviously, the characterization of metalworking machine tools to a higher level is to achieve complete intelligence, and the precursor to this goal is naturally automation. Another exhibit at the Shanghai Machine Tool Plant shows the combination of robots and CNC internal-circle composite grinding machines, which is a step towards automation. In the downstream of machine tools, users are increasingly pursuing high-efficiency, high-precision metal processing equipment represented by automation. Paying attention to the market and satisfying various needs of users naturally becomes the focus of machine tool manufacturers. Hu Hong, president of Qinchuan Machine Tool Group, told the author that Qinchuan Machine Tool has launched a number of high-end CNC machine tools for the aerospace industry and the automotive industry this year. QMK50A CNC blade grinding machine is a five-axis CNC grinding machine. The five axes all use full-closed servo control. The grinding wheel frame uses the torque motor of Siemens to ensure high-precision grinding of various complex curved workpieces. QMK008 precision broach CNC forming grinding machine adopts high precision grating feedback CNC spindle and high precision, high efficiency and high anti-interference ability SEIMENS8400 digital servo system to achieve high precision broach grinding; other such as VMT80/100 vertical milling machine A series of high-end machine tool exhibits such as composite machining center and YK7332B CNC forming grinding wheel grinding machine are also developed by Qinchuan Machine Tool to meet the processing of aero-engine parts. There are three major national special items in the exhibits. Hu Hong said that Qinchuan Machine Tool has formulated a complete "Twelfth Five-Year" development plan. In the strategic direction of the enterprise, it will firmly grasp the key point of innovation, and further advance in high-end products, aiming at foreign advanced level, in each Every step and every component must meet the user's requirements to the greatest extent, especially the highly automated production equipment. Now, no matter in which industry, from the production process of cutting, spot welding, arc welding, painting, handling, loading and unloading, assembly, testing, etc., to packaging and storage, the figure of industrial robots can be seen everywhere on the production line. A modern, unmanned, fully automated production line prototype has emerged in various industry sectors, and it will bring huge economic and social benefits, and its impact can be said to be no less than the first industrial revolution. . Faced with this new opportunity, many companies are eager to try and gain the lead in entering this field as soon as possible. Guangzhou CNC has been involved in the research and development of industrial robots a few years ago. At present, it has made breakthroughs: the company will first use dozens of robots in mass production in its own production workshop; Dalian Machine Tool has launched research and development for China National Nuclear Corporation. A flexible machining combination consisting of a machining center, twin-spindle CNC lathe and a robot. This flexible processing combination has a leading significance for the transformation of the organization and organization, and the industrial automation and the future production mode of the manufacturing industry are self-evident. Based on the experience of developing the Feiyang CNC system, Shenyang Machine Tool Group is also preparing to enter the field of industrial robot manufacturing. Of course, it is not enough for a modern automated assembly line to have only industrial robots instead of labor. The latest achievements in science and technology in other fields are indispensable. In fact, industrial robot technology is moving to intelligent machines and intelligent systems. The development direction and penetration of the direction are mainly the modularization and reconfigurability of the structure, the openness of control technology, PC and network, the digitization and decentralization of servo drive technology, and the practical application of multi-sensor fusion technology. The optimization of the working environment design and the flexibility of the operation, as well as the network and intelligentization of the system, the direction and development trend of the upgrade of domestic high-end machine tool products are based on this. Machine tool companies have mastered these technologies, and it is inevitable to enter the field of robotics. It is a matter of course to realize itself and provide automation industry pipelines to other user industries. In short, whether it is the only way of industrialization, or the change of China's national conditions or the changes of the world's industrial economy, this conclusion can be drawn from the observations of major international exhibitions such as Shanghai International Machine Tool Show, namely: height Automated and intelligent production lines will become a reality in all areas of manufacturing, although we still have a long way to go.
About the calculation of weight and area:
- The weight of gratings varies after end welded and hot galvanizing process. For normal industrial platform using 30mm pitch bearing bars, the weight will increase 12%; 14% for 40mm pitch bearing bars and 16% for 60mm pitch bearing bars.
- For those gratings processed according to size applied by customer, calculation will be based on the total outside size (including cutout and tap)
- For those gratings processed according to customer's drawing, calculation will be based on the total outside size (including cutout and tap)
- For unusual size of gratings cutouts shall not deduct from the length and width.
