### Foreword
Among the various types of machinery and electronic products we are in contact with, accessories stamping parts exist.They have different shapes and diverse functions, but their manufacturing process and quality control are often not known for the public.So, how do these seemingly simple metal parts be produced and how to ensure their high quality?This article will take you into the process of the process and quality control of the stamping part of the accessories, and unveil the scientific veil behind it.
### The process process of the stamping part of the accessories
The production process of accessories stamping parts starts with the choice of raw materials.The commonly used materials include steel plates, aluminum plates, copper plates, etc. Choosing appropriate materials according to different application scenarios is the primary step to ensure the performance of stamping parts.
** The first step: material preparation and feeding **
The raw materials need to be tailored into a certain size board, which is what we call the feeding.The accuracy of the feeding directly affects the quality of the follow -up process, so in this session, tailoring equipment and operating specifications need to be strictly controlled.
** Step 2: Pouring for molding **
After the feeding is completed, enter the core stamping molding stage.In this process, the plate was applied to the stamping mold, and the plastic deformation occurred to form the required shape.The stamping process can be divided into multi -process, such as falling materials, punching, bending, pulling depth, etc.Each stamping operation requires precise adjustment of the mold and precise control of pressure to avoid defects such as burrs and cracks.
** Step 3: Repair and Plastic Surgery **
The parts after stamping and molding often have extra corner materials. At this time, you need to repair edges.The accessories after repair may also perform plastic surgery to ensure size accuracy and surface flatness.
** Step 4: Surface treatment **
Completing the preliminary type of stamping parts often require surface treatment, including electroplating, painting, and anode oxidation to improve its corrosion resistance and decorative.
### Key links of quality control
In the production of parts stamping parts, quality control runs through every link.The following are several key control points:
** Material quality inspection **
Before production, the quality inspection of raw materials is crucial.Through chemical component analysis and mechanical performance testing, the material’s composition, thickness, and strength meet the design requirements.
** Mold accuracy management **
The mold is the core tool of stamping molding, and its accuracy directly affects the quality of stamping parts.Therefore, mold inspections and maintenance need to be regularly carried out to ensure that the mold is not worn and deforms.
** Process monitoring **
During each stage of stamping, real -time monitoring is very necessary.Through high -precision sensors and automation control systems, problems in production can be discovered and corrected in time, such as uneven pressure and inaccurate positioning.
** finished product inspection **
The final finished product inspection includes size testing, appearance inspection and performance testing.Using high -precision detection equipment such as three -coordinate measuring machine (CMM) to ensure that each factory product meets design standards and customer requirements.
### Case analysis
Taking the car engine bracket as an example, this is a typical complex punching part.In order to ensure its strength and accuracy, we optimize mold design through finite element analysis, and use high -precision servo pressure machines in production to achieve refined processing.Each batch of products is tested and dynamic balance testing to ensure its stability and safety under complex load.
In the world of stamping parts, the process and quality control are like a pair of partners who go hand in hand to ensure that each part is not only beautiful, but also excellent.It is these fine technical and scientific management that provide a solid guarantee for our modern life.In the future, with the continuous innovation of technology, the production of accessories stamping parts will move in a more efficient and intelligent direction.
