1、 Analysis and Application of Automotive Stamping Parts

1. Reasonably set process holes

To address issues caused by materials, manufacturing personnel can select appropriate positions to punch process holes during the stretching of the blank, or they can also punch process holes at variable positions during the stretching process. The process holes produced by stamping should be of appropriate size, neither too large nor too small. If the process hole is too large, the hardware stamping parts are prone to flipping holes; If the hole is too small, the top of the process part cannot be fully filled, making it impossible for the material to enter the part, resulting in necking around the top process hole.

2. Reasonable setting of process supplements

The process supplementation in automotive parts provides a foundation for qualified parts. During the production process, material supplementation is carried out on the premise of stamping the parts, which not only has an important relationship with the forming of the blank stretched parts, but also has an inseparable connection with the subsequent related processes. During the manufacturing process of automotive parts, when the parts formed by stretching have large gaps, significant losses may occur due to the inability of the blank to supplement external materials during stretching, resulting in substandard parts. In order to reduce the occurrence of this phenomenon, the automotive manufacturing industry has conducted relevant analysis and research, and decided to reserve material resources that need to be supplemented during the pre forming stage of the blank, to help timely supplement the blank with gaps.

3. Improvement of Automobile Mold

For common parts in automotive manufacturing, if both sides of the part need to be modified, in order to facilitate process operation and enable production to freely place the parts. In general, the construction and trimming method of diagonal wedges on both sides is often used for automotive parts molds.

2、 Points for Attention in Stamping Die Forging

To ensure the overall quality of stamping die forging, in addition to selecting materials for stamping die production, standardizing the steps of stamping die forging, it is also necessary to comprehensively grasp the precautions during stamping die forging. Generally speaking, the key points of stamping die forging can be summarized into three aspects: forging technology, forging time, and forging strength.

1. Die Forging Technology for Stamping Parts

The stamping die forging technology is to grasp the key points of stamping die forging from the perspective of forging personnel. If the processing personnel can accurately grasp the focus of mold forging practice on the basis of standardizing the forging methods of stamping parts molds, and accurately strike the forging position of stamping parts molds, it can avoid the problem of residual forging defects during the forging process of stamping parts molds. When adjusting the molds in the later stage, it will naturally reduce the possibility of damage to the hardware stamping parts molds; On the contrary, if stamping die forging personnel cannot master the skills of die forging, the standardized and standardized production of die materials cannot be achieved. This also explains why some stamping die production processes are seamless, while some stamping die forging processes require subsequent adjustments.

2. Stamping part mold forging time

The forging time of stamping parts molds is a method of grasping the forging manufacturing of stamping parts molds from the perspective of the physical characteristics of the materials used in the production of stamping parts molds. During the forging process of stamping parts molds, production personnel should grasp the production of small parts
