Solutions to problems of automotive precision stamping parts [hardware]

Automotive precision stamping parts have a rich variety of products and complex shapes. Generally speaking, precision metal stamping can process small auto parts with a small size range and a more complex shape. However, during stamping production, some undesirable phenomena may occur. How to avoid these problems has become the primary problem in processing high-quality stamping parts. The middle protective surface bracket is the key load-bearing connection of the integral instrument panel assembly of the automobile cab, and is an important part to ensure the stable and reliable use of various instruments of the automobile. Because the high-speed rotation of the high-power engine and the poor driving conditions of the vehicle are likely to cause strong vibration and turbulence to the cab, which may cause disconnection or failure of the instrument circuit and some functions in the front control panel. Therefore, the intermediate shield support must be able to withstand impact, bending fatigue load and torque, so it must have sufficient bending strength, shear strength and good toughness. In addition, if the part exceeds its applied force during forming, or the microcracks expand to a certain extent, causing tearing or skewing, this will not only waste material, but also put the mold in eccentric load operation and accelerate mold aging. The instrument panel bracket assembly was produced in the automobile cab. It was found that after the production of precision stamping parts, the left/right brackets of the middle protective surface often appeared torn and skewed. These defects were mainly distributed in the hole pattern of the workpiece and the corners of the side walls. And R arc and the junction of the wall neck. After careful analysis, it is believed that the main reasons are the unstable forming and guiding of the die during the operation of the die, the unadjustable gap between the die and the die after long-term wear, and the improper die structure design. Therefore, corresponding control measures can be proposed from both technical and management aspects, and provide references for similar parts technology, precision metal stamping die design and forming processing.
