The development status of China's automotive stamping technology is reflected in the following aspects.
First, the degree of automated production of the outside coverage is higher. The outside coverage puts forward high requirements on the surface quality, and only relies on automated production. While the cover automated production of motor vehicles in China is not high-speed Metal Stamping Dies, but the degree of automation is also quite high. This was reflected in the widespread adoption of automation into line stamping. A complete closed stamping line is normally made of four presses to form in to a line of stamping and the automatic feed and pickup in the middle are completed by the robots. The production takt is about 10 to 15 times / min which is the first typical combination of the double action 1630T and the subsequent 800T press.
Second, floors and covers take the use of the automatic or semi-automated production
The production methods of such parts are determined mainly by the bulk and its generally take the use of automated or semi-automated production. Besides the joint venture, a great number of local enterprises initially started basically using a semi-automated stamping production. Semi-automatic stamping put forward the specific requirements on the stamping presses. Firstly, press countertops should in the large size; Secondly, due to the forming force is too large, you firstly need the press of 2000T or 2400T, the subsequent press 1000T or 1250T.
Third, chassis skeleton parts are made by the parts manufacturing enterprises
Chassis skeleton parts are manufactured by parts companies and are sent to the OEMs. Parts of a large scale companies have generally six punch lines, taking into account the production logistics management to facilitate quality control and OEMs, such Mold Making Supplies companies have welding and even follow-up paint or spray process, which can be provided directly to OEMs total into components.
Fourth, Precision stamping technology is developing rapidly
Along with the development of the watch manufacturing, precision stamping technology is originated in Switzerland, which is one of the key technologies in the development of automobile industry, and has an important application in car assembly manufacturing, such as door hinge assembly, glass lifter assembly. The thickness of such parts of the material is 3-5mm, which requires high precision and high strength of parts with smooth and reliable assembly action.
