Metal stamping parts in their own economic and structural aspects of a unique superiority. Mainly in: metal stamping parts of the production of high efficiency, and easy to operate, easy to achieve mechanization and automation. Formal stamping parts due to the stamping parts of the size and shape accuracy, only to make the quality of stamping, interchangeability. Since stamping parts have so many benefits, how can we improve the quality of stamping parts production?
Automotive metal stamping parts processing products are rich, complex shape. In general, metal stamping can be processed into smaller size, the shape of the more complex small car parts. However, in the stamping production, there may be some bad phenomenon, how to avoid these problems, has become the processing of high-quality stamping parts of the primary problem. In response to the above problems, our company for your reorganization of the contents:
The intermediate support bracket is the key load-bearing connector for the car's integral dashboard assembly, which is an important part for ensuring the stability and reliability of all kinds of instruments. Because of the high-speed rotation of the high-power engine and the poor traffic conditions of the vehicle, it is easy to cause strong vibration and bumps to the cab, resulting in the instrument circuit and some functions of the front control disk.
Therefore, the middle face bracket must be able to withstand the impact, bending fatigue load and torque and so on, it is required to have sufficient bending strength, shear strength and good toughness. In addition, if the part exceeds the allowable stress at the time of forming, or the microcracks are extended to a certain extent, tearing or skewing is caused, which not only wastes the material, but also causes the mold to be in the eccentric operation and accelerates the aging of the mold.
In the automobile cab dashboard bracket assembly production, found that metal stamping production, the middle face of the left / right bracket often tear, skew phenomenon, these defects are mainly distributed in the workpiece hole, the corner of the sidewall and R at the junction of the arc and the wall.
After careful analysis, we believe that the main reason is that the mold in the course of the operation of the pressure core forming guide instability, die and paste the gap between the long-term wear can not be adjusted and the mold structure caused by improper design. So, from the technical and management aspects of the corresponding control measures, and for similar parts technology, mold design and forming processing to provide a reference.
