How can the production quality of stamping parts be improved? Automobile stamping parts have a wide variety of products and complex shapes, and some undesirable phenomena often occur during stamping production.

The middle guard bracket is the key load-bearing connection part of the integral instrument panel assembly of the automobile cab, and is an important part to ensure the stable and reliable use of various automobile instruments. 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 middle shield bracket 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 the allowable stress 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.
