### Foreword
Playing parts are widely used in modern manufacturing, and its quality directly affects the performance and life of the product.However, in the production process, various defects occur from time to time, affecting the quality and use effect of the punching parts.This article will explore several common stamping parts defects, analyze the causes, and propose practical solutions in order to provide reference for relevant practitioners.
### crack defect and solution
** Crack ** is one of the most common and serious flaws in the production of stamping parts.The production of cracks is usually related to the performance, mold design, and stamping process parameters of the material.
In terms of materials, if the material of the material is poor or the thickness is not uniform, it can easily lead to stress concentration and cause cracks.At this time, you should choose materials with better plastic properties for processing.
Improper designs, such as the radius of the rounded corner is too small or the mold space is unreasonable, which will increase the risk of cracks.To prevent this, ** It is recommended to optimize the design of the mold, appropriately increase the radius of the rounded corner and adjust the mold space ** to reduce the stress concentration.
In the stamping process, if the stamping speed is too fast or insufficient, it can also cause cracks.Therefore, controlling stamping speed and reasonable use of lubricants during the process can significantly reduce the occurrence of cracks.
### Lift deformation defects and solutions
** Turbish deformation ** is another common stamping parts defect, which is usually manifested as the poor plane of the workpiece.The causes of warming and deformation mainly include the internal stress of the material, uneven mold pressure, and uneven heating or cooling process.
The internal stress of the material itself is one of the important reasons that leads to warning.In the process of stamping, ** pre -processes the material in advance, which can effectively release the internal stress, thereby reducing deformation.
Unemployment of mold pressure will cause different force in each part of the stamping parts, which will lead to warp.To this end, ** can ensure that the workpiece is uniformly stressed by adjusting the technical means of the mold pressure distribution **.
The uneven heating or cooling process can cause the material to swell or contrast, which causes warp.Therefore, in the design of process design, we must ensure that the workpiece is uniformly heated or cooled ** to avoid stress caused by temperature difference.
### Surface scratches and solutions
** Surface scratches ** Although the structural strength of the workpiece has a small impact, it seriously affects the appearance quality.Scratches are usually caused by the surface wear of the mold, impurities on the surface of the material, or improper operation.
If the surface of the mold is worn or attached, the surface of the workpiece will be scratched during stamping.Therefore, ** regular inspection and cleaning mold surface **, it is very important to keep the good state of the mold.
The impurities attached to the material surface are also one of the sources of scratches. Therefore, before stamping, we must clean the surface of the material to ensure that there is no impurities.
In addition, during the operation, the correct location and state of the workpiece should be maintained to prevent unnecessary friction with equipment or molds.
### Bond defect and solution
The ** burrs of stamping parts usually appear on the edge of the shear or tailoring, which is the result that the material fails to completely separate the material during the shear process.The burrs affect the assembly and use performance of workpieces.
The cause of the burr may be related to the wear of the mold blade, unreasonable gap, and too fast stamping speed.
Demonstration of mold blade is one of the main reasons for the occurrence of burrs. Termia and grinding the mold blade port on a regular basis can effectively reduce the formation of the burrs.
If the gap between the mold is too large or too small, the shear will be incomplete.Therefore, ** reasonably adjust the mold gap **, so that it can match the thickness of the material, which can reduce the rate of burning.
In addition, controlling the appropriate stamping speed to ensure that the material has enough time to cut and separate, and it can also effectively reduce the burrs.
### Summarize
The occurrence of stamping parts is often the result of the common role of various factors.Through reasonable selection of materials, optimization of mold design, and fine chemical technology control, many common defects can be effectively solved.For practitioners, understanding the causes and solutions of these defects not only help improve product quality, but also improve production efficiency and economic benefits.By continuously optimizing the production process and strengthening quality control, manufacturing can achieve more fine and efficient production.
