Iron shavings briquetting machine is mainly used for all kinds of scrap metal, scrap iron, copper scrap, aluminum scrap, etc.), powder, granular powder, metal smelting additives, sponge iron bearing etc. Without any adhesion agent, the block (weight 2-8 kg) density can reach more than 5 t/M3, the briquettes can directly be used in furnace. Independent electrical control system, reliable operation, intuitive operation, easy maintenance.

In a simulated system integration factory shop, three robots on the production line were observed to be in operation. Parts, drying, cutting, and discharging from the machine were all completed by these three robots. Most of these robots are used for handling and welding and can work 24 hours a day.
"Upstream is the core component, the main one is the speed reducer and control system, which is equivalent to the robot's 'brain', the midstream is the robot body, is the robot's 'body', and the downstream is the system integrator, 95% of the domestic companies are concentrated. In this link," He Yingwu, deputy chief engineer of Guangzhou CNC, summarized.
Judging from the use density of robots, the current density of industrial robots in China is still far below the global average, and it is far from the developed countries such as Japan, South Korea and Germany. South Korea is the country with the highest density of industrial robots in the world, with 347 robots per 10,000 workers; Japan is second with 339; Germany is ranked third with 251; China is only 21, less than the international average of 55 Half of the station. At present, the proportion of industrial robots used in China is 6%, Japan 33%, the United States 16%, and Germany 14%.
From the perspective of the place of production and consumption, Japan is the only net exporter of robots. It has the world’s largest robot production capacity and accounts for 66% of global robot production. The largest region where robots are consumed is in Asia except Japan, which accounts for about 34% of the total, and is dominated by the Chinese market.
In terms of comparison of advantages of robotics technologies in various regions, analyst Liu Guoqing of Huachuang Securities believes that Japan has obvious advantages in industrial robots and home robots. Europe has a leading position in the field of industrial robots and medical robots. The main advantage of the United States is in the field of system integration, medical care. Robot and defense military robot.
"South Korea attaches great importance to service type (such as education, entertainment) robots, which dominate the standards of this type of robots; the United States dominates high-end robots such as exploration and explosion-proof light function robots; Japan’s industrial robots are excellent and cheaper than ABB; and Sweden’s ABB represents Europe's technology, the process is very exquisite, has the most complete and best industrial chain." He Yingwu, deputy chief engineer of Guangzhou CNC told.
"The speed reducer is the click speed to use it to reduce the speed to the applicable speed of the robot. Generally a robot body generally has 6 speed reducers, 1 to 3 axes are used by the Japanese Teijin reducer, the company's The reducer is used almost all over the world, and the 4 to 6 axes are used by our own R & D. However, our reducer is still immature and cannot be produced in batches," He Yingwu told.
At present, the profit value of the upper reaches of the robot is the highest. The speed reducer only accounts for about 35% of the cost of the robot, and the motor and controller account for about 10%. Due to the high cost of key components and the negative gross profit margin, domestic robots maintain a relatively high level of gross margins in all aspects of the robot industry chain, of which the highest level of gross profit margin for medical surgical robots is close to more than 70%.
At present, the domestic reducers, servomotors and drives used by robots are mainly supplied by foreign countries, of which Japan is the largest exporter of reducers. The domestic listed companies for the development of reducers and the listed companies are Qinchuan Development and Huaheng Welding, Huichuan Technology, Inventronics, Keyuan Stock, and Huazhong CNC development drive. Among non-listed companies, Guangzhou CNC and Nanjing Estun have not involved in the mass production of the speed reducer, and all aspects of the robot have involved.
Manufacturers of robotics such as Shanghai Mechatronics, Qinchuan Development, Suzhou Luxin, Nantong Zhenkang and other companies adopt joint ventures or independent research and development, and are actively entering the field of precision reducers. “But the current domestic market competition is very fierce, foreign-funded brands and domestic brands joint research and development is unlikely, because this involves the core technology, foreign brands can not be leaked.†He Yingwu frankly.
Focus on core technologies The level of application of industrial robots in China needs to be improved
At present, there are a total of 31 listed companies involved in robots, with a total market value of 189.707 billion yuan, and currently robotic leading companies are already approaching 60 billion in market value. The global industrial robot body market is dominated by China, Europe, and Japan. Japan, the United States, Germany, South Korea, and the five countries accounted for 71.24% of the world's stock, with sales of 69.92%.
