### Foreword
In the modern manufacturing industry, large stamping parts processing play a vital role, and its quality directly affects product performance in high -end manufacturing fields such as automobiles and aviation.However, various problems will inevitably encounter in the processing process. How to effectively take these problems and become the key to improving the quality of the product.This article will be discussed around the common problems and response strategies in large stamping parts processing to help readers deeply understand and optimize the production process.
### Cracking and Fracture: Material selection and process optimization
In the processing of large stamping parts,*cracking and broken*is one of the most common and serious problems.This is usually related to the plasticity, stamping speed, and mold design of the material.To solve this problem, first of all, it is necessary to strictly check the selection of ** materials, and select materials with good plasticity and toughness.At the same time, adjusting the stamping speed appropriately, too high speed will cause the material to break and break the deformation, and too low will affect production efficiency.
A typical case is that a car manufacturer frequently appears edge cracking when producing body coverage.After analysis, it was found that it was caused by insufficient material plasticity and unreasonable mold design.Solution includes replacing high -plastic materials and optimizing mold design, re -adjusted the stamping angle, and finally successfully reduced the cracking rate.
### wrinkles and ripples: optimize mold design and lubrication conditions
*The occurrence of wrinkles and ripples*is usually related to the uneven flow of materials, improper gaps in the mold, and poor lubrication conditions.Wrinkles not only affect the appearance of the product, but also cause reduction in strength.Optimizing mold design, reasonable setting mold gap, and improving lubrication conditions are an effective way to solve this problem.
For example, an aviation component supplier found obvious ripples on the surface when producing large -scale winged components.After research, it was decided to add support points to the design of the mold and optimize the liquidity of lubricating oil.This series of measures effectively improve the flow of the material, thereby reducing the phenomenon of wrinkle.
### Dimension deviation: strict control process parameters and regular calibration equipment
During the processing of large stamping parts,*size deviation*is a problem that cannot be ignored.Size deviation may be caused by mold wear, decreased equipment accuracy, and improper control of process parameters.In order to ensure the accuracy of the size, enterprises need to strictly control the process parameters, calibrate the equipment regularly, and timely maintain and update the mold.
When a well -known home appliance company produces large stainless steel panels, the finished product rate is low due to size deviation.Through precise calibration of stamping equipment, and strictly formulating and executing process parameters, the size deviation has been effectively controlled, and the product quality is significantly improved.
### Surface scratching and indentation: Strengthen mold maintenance and environmental management
*Surface scratching and indentation*not only affect product aesthetics, but also may cause stress concentration and affect service life.This problem is mostly caused by the surface of the mold, the invasion of foreign body, and the poor environmental management.Strengthen mold maintenance, clean up the working environment regularly, strictly control foreign body intrusion, can effectively reduce the occurrence of such problems.
A large number of products have reworked in a large number of products due to surface scratches.By strengthening the surface treatment of the mold and the environmental management of the workshop, regularly clean up foreign bodies, and the quality of the final product surface has been significantly improved.
### rebound problem: precise simulation and material pre -processing
After the stamping part is formed, the bounce*will affect the preparation accuracy.The rebound is closely related to material characteristics, forming technology, and mold design.The CAE software is used for precise simulation, combined with the pre -processing of the material, such as the appropriate annealing process, adjusting the forming angle, etc., can effectively control the rebound volume.
A well -known mechanical manufacturing enterprise has introduced the advanced CAE analysis technology to simulate and optimize the hedging process, successfully reducing the rebound problem of complex components, and ensuring product assembly accuracy.
### in conclusion
In the process of large stamping parts, in the face of various problems, enterprises need to adopt practical and effective response strategies in combination with scientific analysis and practical experience.Through material selection, mold design optimization, process parameter control and equipment maintenance, comprehensive measures can significantly improve product quality and ensure production efficiency and product reliability.This is not only helpful to enhance the market competitiveness of the enterprise, but also has positive significance for promoting the technological progress of the entire manufacturing industry.
