At present, there are about 4 million production enterprises in China's stamping industry, 2 million employees, the annual production of 28 million tons of stamping parts, total sales of 400 billion yuan, about 40000000 tons of thin steel sheet under 3 millimeters per year, 40 billion yuan for purchase of stamping die, and 20 billion yuan for new purchase of stamping equipment. There are 30 thousand enterprises in China's sheet metal and manufacturing industry, and 1 million 800 thousand employees. The annual production of sheet metal parts is about 42 million tons, with a total sales volume of 500 billion yuan.
Stamping and sheet metal production involves many aspects of the manufacturing industry. It can be seen in a wide range of shapes and processes. In the past ten years, as China has become a world manufacturing center and a big consumer country, the stamping and sheet metal industry, as one of the basic manufacturing industries, has also made unprecedented development.
In contrast to the current situation of stamping and sheet metal processing enterprises at home and abroad, Qi Jun River chose the United States and Japan as a reference. The biggest difference between Chinese and American stamping and sheet metal enterprises is the difference between automation and informatization level.
First, the closed-loop production automation adopted by American enterprises is more secure and reliable, and is convenient for the maintenance of the entire production line. The enterprise has its tooling maintenance workshop, and various sensors are installed or embedded in the mold. The application of these sensors greatly improves the safety and reliability of the whole production line.
Second, the safety awareness of American stamping and sheet metal enterprises is high. The safety grating is installed on the press. When the worker approaches the press, the pressure is automatically shut down, thus ensuring the safety of the workers.
Thirdly, American enterprises have their own management information system. The materials supplied by the raw material suppliers are all provided with bar code, and all kinds of information of the raw materials will automatically enter the production database by scanning during storage. As the raw material enters the processing process, the computer hosts in each processing link automatically input the processing information into the database, which will be attached to the final product.
