Metal stamping parts processing has unique advantages in its own economy and structure. The main performance is: the production efficiency of metal stamping parts processing is high, and easy to operate, easy to realize mechanization and automation. Due to the size and shape accuracy of stamping parts, the stamping quality is not disordered and the interchangeability is good. Since stamping has so many advantages, how to improve the quality of stamping parts?
Automobile metal stamping parts processing products are rich in variety and complex in shape. Generally speaking, metal stamping can process small automobile parts with small size range and complex shape. However, in stamping production, there may be some bad phenomena. How to avoid these problems has become the primary problem in processing high-quality stamping parts. In view of the above problems, Cangzhou Fuxu electromechanical products manufacturing Co., Ltd. has compiled the following contents for you:
The middle shield bracket is the key load-bearing connector of the integral instrument panel assembly in the driver’s cab. It is an important part to ensure the stable and reliable use of various instruments. Because of the high-speed rotation of the high-power engine and the bad road conditions of the vehicle, it is easy to cause strong vibration and turbulence to the cab, resulting in open circuit or failure of the instrument circuit and some functions in the front control panel. Therefore, the intermediate armor support must be able to withstand the impact, bending fatigue load and torque, so it must have sufficient bending strength, shear strength and good toughness. In addition, if the part exceeds the allowable stress or microcracks extend to a certain extent, resulting in tearing or skewing, it will not only waste materials, but also make the die in eccentric load operation, accelerating the aging of the die.
In the production of automobile cab dashboard bracket assembly, it is found that after metal stamping, the left / right bracket of the middle cover often appears tearing and skew. These defects mainly distribute at the hole type, the corner of side wall and the junction of R arc and wall neck. After careful analysis, we think that the main reasons are the instability of the forming guide of the die core during the operation of the die, the gap between the die and the core can not be adjusted after long-term wear, and the improper design of the die structure. Therefore, the corresponding control measures can be put forward from two aspects of technology and management, and provide reference for similar parts process, die design and forming processing.
