The development status of precision stamping parts stamping technology

With the unsustainable low-cost human resources in our country and the continuous development of science and technology, the automation and intelligent manufacturing of precision stamping parts will inevitably become an important development direction of modern manufacturing, and intelligent molds will also develop rapidly. Using smart molds to produce products can further improve product quality and production efficiency, save materials, and realize automated production and green manufacturing. The environmental protection of the mold manufacturing industry has promoted the development of environmentally friendly production and environmentally friendly processes in the precision stamping parts industry. Therefore, although the total amount of smart molds is not large at present, it represents the new development direction of mold technology and will play an increasingly important role in the adjustment of industry product structure and the transformation of development mode. The development of smart molds will inevitably play a powerful role in promoting the rapid improvement of the entire mold industry. Therefore, it is particularly necessary to give priority to the development of smart molds in the development of the industry. It is also imperative for the precision stamping parts industry to adopt higher-end molds. The development status of my country's automotive precision stamping parts stamping technology is shown in the following aspects. 1. High degree of automatic production of outer covering parts. Outer covering parts have high requirements for surface quality and can only rely on automated production. Although the automated production of automobile outer panels in my country is not high-speed stamping, the degree of automation is quite high. This is mainly manifested in the widespread use of automated line stamping. In-line stamping generally consists of 4 presses to form a complete closed stamping line, in the middle is the robot automatic feeding and picking, the production cycle is about 10-15 times/min, typically the first double-acting 1630T and the subsequent 800T Composed of the press. 2. Automatic or semi-automatic production is adopted for the inner covering parts of the floor and roof. The production method of this kind of parts is mainly determined by the batch, and the automatic or semi-automatic production is generally adopted. Except for joint ventures, local companies basically adopted semi-automatic stamping production methods at the beginning. Semi-automatic stamping puts forward specific requirements on the press. Firstly, the press table should be large; secondly, due to the large forming force, the first press needs to be 2000T or 2400T, and the subsequent press is 1000T or more than 1250T. 3. Chassis skeleton parts are mostly manufactured by parts companies. Chassis skeleton parts are mostly manufactured by parts companies and sent to OEMs. Large-scale parts companies generally have 6 stamping lines. Considering the convenience of quality control and production logistics management of the OEM, these parts companies have welding and even subsequent painting or spraying processes, so that they can directly provide total Into parts. 4. The rapid development of precision stamping technology. Precision stamping technology originated in Switzerland along with the development of the watch manufacturing industry. It is one of the key technologies in the development of the automotive industry. It has important applications in the manufacturing of some automotive assemblies, such as door hinge assemblies, Glass lifter assembly, etc. The thickness of this kind of parts is 3-5mm, which requires parts with high precision, good strength, and smooth and reliable assembly movements. After years of development, precision stamping technology has made gratifying achievements in my country's automobile industry. At present, a number of powerful fine-blanking enterprises have emerged in my country.
