Shanghai auto, was once after the founding of new China the first batch of independent brands, although fame than the red flag, but also on behalf of an important symbol of China's automobile industry. A few years later, face a new Shanghai automotive group once again become a independent car companies in China, no matter in the brand building, product research and development, production, or sales promotion, all is a high level of independent domestic automakers. All say quality is the lifeline of the enterprise, at the start of the order of the phoenix cars made in China), we first came to Shanghai lingang factory, let you understand with experience in the true level of Chinese indigenous car companies manufacturing.

Saic group passenger car company, currently has two brands roewe and MG, there are five major platforms dozens of models, in Shanghai, nanjing and Britain has three technology research and development centers, locates in Shanghai, nanjing pukou has three manufacturing bases and the longbridge, annual production capacity of more than 500000 vehicles, there are almost half of the product is in lingang factory production. Located in Shanghai pudong new area lingang heavy equipment industry area of the factory, in June 2006 to start the build, on September 19, 2008, the first roewe 550 models offline, is developing rapidly.

Shanghai lingang factory covers an area of 1.2071 million square meters, a total of stamping, engine, body, paint and assembly production workshop, 5 so far has invested 2.5 billion yuan, the phase ii of the ongoing successor will also be an increase of 3.8 billion yuan, total is 6.3 billion yuan RMB. At present, there are five models in lingang communist production, including the roewe 550, 950, E50 and MG3, car.

Stamping is the first link in automobile manufacturing, the original steel after punching into body body side wai, doors, hood and other components. Saic lingang factory stamping plant a total area of 18075 square meters, owns 1 automation open-book blanking line and three automation press line, the whole machine workshop, the highest degree of automation is the plant, so are the least number of employees is relatively, only 113 people, and the whole plant has nearly 2000 employees.
 

Open book in front of the blanking and punching cannot little, shipped from the steel mill roll steel, must first be straighten and cut into the size and shape of the punching machine can be used, and the link to clean steel, even to go out to the surface of dust, grease and other impurities, ensure the quality from the raw materials. Lingang factory open-book blanking line imported from Spain FAGOR automation, equipment investment is 67.09 million yuan, the technical specification belongs to the international advanced level, high production efficiency, high speed, easy to safeguard press line needs 3 days.

Saic passenger car chooses the steel are from domestic large steel mills, such as baosteel, wisco, and anshan iron and steel, quality guaranteed. At the same time, there are some material directly buy from other companies, such as the world top 500 thyssenkrupp provides two kinds of material are connected to the thickness of plate, and some of the aluminum alloy plate, etc.

Stamping production is the key to die that is the key to ensure the quality of production and precision, the whole plant a total of 60 sets of stamping die, a total investment of 190 million yuan, up and down the value of each set are LiangSanBaiWan. Mould value not only expensive, the volume and weight are huge, in the stamping workshop, large area is used to store the dozens of tons of big guy, we need to rely on in the transportation link overhead crane and trolley/trackless flat car.

Decoiling blanking plate was shipped to stamping production line, saic lingang factory three press line parallel arranged, line 1 # and 2 # line made by jinan 2 machine tool group is responsible for the domestic, key components are also adopted the United States or Japan imported products, such as 6 axis of FANUC robots, the overall level also belongs to the advanced level in domestic automakers. Among them 1 # line has 4 sets of punching machine, punch line 2 # by 5, is provided with four and five stamping production process, a single line production fastest speed can reach 8 pieces/minute.

Stamping 3 # line from Japan komatsu KOMAT 'SU design and manufacturing, technical level has reached international advanced level, the arms and high-speed rail transport system, a magnetic levitation motor drive, production speed is twice the line 1 # and 2 # line, up to 16 pieces/minute. 4 sets of punching machine with high speed servo technology, is more advantageous to material forming, drawing effect is good. Deep drawing pad current feedback power grid in the deep drawing process, also is in the press the power stroke can be recycled current, thus more energy conservation and environmental protection.

While stamping workshop of a high degree of automation, the main work is done by machine, but artificial at this stage is also an indispensable element, in addition to responsible for the operation, monitoring and maintenance, in each line terminal receipt or are done by people, the main purpose is also in the collection of the necessary inspection at the beginning of the workers through soon, hand to touch to check whether the stamping parts surface is smooth, stamping parts are in good condition, this is a simple and effective method.

In Shanghai lingang factory, emphasize the practice of "manufacturing quality" concept everywhere, in addition to having the overall high technical content of hardware, the militarized management staff quality is high, strictly the quality pass, in every link of self-inspection, mutual inspection, and 300% of the qc inspection, to ensure that the problem and end in the current segment. So, we can see there are production department staff self-checking, also have sampling observation of quality supervision department, and the introduction of audiT quality evaluation mechanism, to produce products for effective internal supervision.

Play to workers' intelligence in a high degree of automation also play an important role in modern industry, the rationalization proposal, for continuous improvement is the characteristic of lingang factory production technology, and thus gain a series of achievements, such as the prize of the national quality technology "" double stamping workshop laser detection system is developed by the workers themselves.

The concept of logistics is very important in modern manufacturing, dedicated, efficient logistics and storage system is necessary for continuous production, more like in the department for other production services. After stamping the body parts, are connected to the stamping workshop will be shipped to the body shop, where they were welded into a body, the next link will continue to introduce by my colleagues.
