On May 23, the 14th Lijia International Machinery Exhibition was held in Chongqing. In the past 13 years, Lijia exhibition has been held in Chongqing Nanping Convention and Exhibition Center. Due to the restriction of venue area and load-bearing, the scale cannot be expanded. Chen Qi, general manager of Chongqing Lijia Convention and Exhibition Co., Ltd., told China industry news that the relocation of the newly completed Chongqing International Expo Center has given us more room to move, and the scale of the exhibition has almost doubled

cold market and hot exhibition

the five-day exhibition attracted many well-known equipment manufacturers from more than 20 countries, including Germany, the United States, Switzerland, Sweden, Japan, South Korea, Hong Kong, Taiwan and other places in China, with a total of more than 1500 exhibitors, an exhibition area of more than 70000 square meters, more than 2000 sets of various metal processing equipment on display, and more than 80000 pieces of clamping and measuring tools, molds, robots, 3D printers CNC system, casting, high-quality castings, etc. compete on the same platform

sun Mujing, deputy general manager of Chongqing Lijia Convention and Exhibition Co., Ltd., introduced that the overall economic situation in the world is not good, but it is very good for Southwest China, especially for Chongqing machine tool industry market. There is a saying that China's market depends on the southwest, and Chongqing depends on the southwest. In recent years, the market in Chongqing has been relatively good. Exhibitors want to take advantage of this opportunity to get more orders. Under the background of complex and changeable domestic and international economic situation and overcapacity in the machinery industry, the number and scale of exhibitors in this exhibition still increased significantly. It is expected that the on-site transaction volume will exceed 1billion yuan this year, and the intention to sign contracts is close to 10billion yuan

it is reported that more than 30 exhibitors are among the world's top 100 equipment enterprises and 10 are among the world's top 500 enterprises. While foreign customers vie with each other, Chongqing's local enterprises also give way

according to Zhaogang, chief engineer of Chongqing Municipal Commission of economy and information technology, all key equipment manufacturing enterprises in Chongqing participated in the exhibition. Chongqing Machine Tool Group Co., Ltd. participated in the exhibition with a newly developed large-scale precision CNC gear hobbing machine that broke the foreign monopoly, as well as a new generation of CNC high-speed dry cutting gear hobbing machine, digital universal gear grinding machine and automatic production line for car gearbox gear processing. Chongqing tough guy, Honggang, Jiuyuan, etc. brought their newly developed CNC machine tools and other products to the exhibition

at the same time of displaying machine tool products, the Foundry Exhibition Group sponsored by Chongqing Foundry Industry Association has achieved a large-scale breakthrough. There were more than 100 casting and die-casting exhibition enterprises, an increase of 52% over the previous year. Chongqing's well-known enterprises, such as Yujiang, Dajiang meilixin, Zhicheng, Longxin, Zongshen, Baiji Sixing, xinhongqi cylinder head, linteng Electromechanical, etc., showed their high-quality castings

the industrial robot market is promising

according to sunmujing, one of the highlights of this exhibition is industrial robots. Abb, KOMA, Siemens, Guangzhou CNC and other more than ten domestic and foreign industrial robot manufacturing enterprises brought the latest industrial robots, and performed with various advanced machining equipment

the efficiency of one robot can exceed the efficiency of 10~36 workers, and it is safe and environmentally friendly. Therefore, industrial robots have become the development direction of modern industry in the future. Special activities such as high-end industrial robot forum were also held during the conference

at the scene, it was seen that the domestic machine wire rod changing experimental machine was used to measure the ability of metal wire rod to withstand plastic deformation in one-way or two-way change and to show the surface and internal defects of wire rod. The shape of the machine is not different from that of foreign countries. The robot arm can complete the work according to high standards under the specified procedures. Only one arm turned perfectly into a small hole inside the frame for welding

in terms of technology and quality, foreign robot technology is relatively mature. KUKA has been making the first industrial robot since 1973. Shenyang Xingsong, the earliest robot company in China, officially entered the market in 2000

it was learned at the scene that the maximum load of foreign robot arms such as KUKA can reach 1300 kg, while that of domestic robots is about 100 kg

in fact, it is the high price of foreign robots that provides opportunities for domestic self-developed robots. The domestic middle and low-end market has become an important territory for domestic robot manufacturers. Said Mr. Chen of Guangzhou CNC

price has become the most important factor for domestic brands to challenge foreign brands. Taking robots in the handling industry as an example, the price of foreign robots and their supporting systems is often more than 600000 yuan, while the lowest price of domestic self-developed robots is only 160000 yuan, which is about 260000 yuan more expensive

at the same time, the after-sales service cost of imported robots is also very high. The annual maintenance cost of some products now costs 10000 yuan as a whole

however, it is difficult for domestic robots to shake the domestic market of foreign robots only by relying on the price advantage

large enterprises will still choose foreign brands with excellent technology, while many foreign-funded enterprises only consider the brand robots of their own countries, which makes our market limited to the domestic middle and low-end market. An unnamed brand dealer said that the average annual output of domestic brands is 500~1000 sets

3d printing is widely concerned

according to lubingheng, academician of the Chinese Academy of engineering and director of the National Engineering Research Center for rapid manufacturing, 3D printing is a three-dimensional entity directly made from CAD data, without the need for traditional tools and fixtures, and is not limited by the complexity of part structure and shape. By using 3D printing technology to manufacture molds, the cost can be reduced to 1/3 ~ 1/5 of the traditional processing, and the manufacturing cycle can be shortened to 1/5 ~ 1/10. However, due to the high cost, napoleonbonaparte, the most important founder of 3D printing in France, said in 1818 that the technology was mainly applied in a small number of fields such as scientific testing and research, auto parts, molds and film shooting. The specific situation is subject to the company's after-sales service

in the exhibition hall, 3D printers have become the focus of the audience among the thousands of equipment participating in the exhibition. Next to a nearly 1m high 3D printer, a mini Guangzhou small Manyao TV Tower with the same height was found. Exhibitors said that the 3D printer sold for nearly 30000 yuan, and it took more than 20 hours to print the TV Tower. In another booth, a small 3D printer with a height of 30cm and 40cm is busy printing a stereoscopic horse head with a height of 78cm according to the 3D pictures set by the computer. It is reported that this small printer costs about 10000 yuan, and it takes twoorthree hours to print the horse head

according to the person in charge of a 3D printer manufacturer in Shanghai, 3D printers do not need paper or ink. Instead, specific metal powders or memory materials are melted through electronic mapping, remote data transmission, laser scanning, material melting and other technologies, and they are superimposed layer by layer according to the instructions of the electronic model map, and finally the electronic model map is turned into a physical object. The utility model has the advantage of greatly saving the manufacturing time of industrial samples

3d printing technology has attracted much attention in recent years. At this exhibition, a 3D printing technology demonstration and release seminar was also held. Liuyousheng, a professional from the National Engineering Research Center for rapid manufacturing, introduced the various applications of 3D printing to those present. 3D printing can bring many incredible benefits. Human organs, auto parts, jewelry, glasses, watches and other things can be printed by 3D printers
