Automotive precision metal stamping parts are rich in products and complex in shape. Generally speaking, precision metal stamping can produce small auto parts with smaller dimensions and complex shapes. However, in stamping production, some undesirable phenomena may occur. How to avoid these problems has become the primary problem in processing high-quality stamping parts. The following is a solution to problems related to automotive precision stamping parts.

The mid-surface support is the key load-bearing connection of the overall instrument panel assembly of the automobile cab. It is an important part to ensure the stable and reliable use of various instruments. Due to the high-speed rotation of the high-power engine and the harsh road conditions of the vehicle, the cab is prone to strong vibration and turbulence, which leads to malfunctions or malfunctions of the circuit and some functions of the instrument on the front control panel.

Therefore, the midplane support must be able to withstand impact, bending fatigue loads and torque, so that it has sufficient bending strength, shear strength and good toughness. In addition, if the workpiece is larger than the applied force during forming, or the microcracks extend to a certain extent, causing tearing or skew, not only will material waste, but also the mold will accelerate the aging of the mold during partial load operation.

In the assembly of the car's cab instrument panel bracket, it is found that in the production of precision stamping parts, the left and right brackets on the middle surface often appear torn and skewed. These defects are mainly distributed in the part of the workpiece, the corner of the side wall and the junction of the R arc and the wall neck. After careful analysis, it is believed that the main reason for the mold is that the mold is unstable during the processing of the mold. The mold cannot be adjusted when the mold is worn for a long time and the gap between the core and the core and the mold structure are not properly designed. Therefore, we can propose corresponding control measures from two aspects of technology and management to provide references for the process of similar parts and the design and processing of precision hardware.
