What are the factors that affect the quality of precision stamped parts?
Precision stamping parts are thin,uniform,light and strong.Stamping can make workpieces with ribs,ribs,undulations or flanging that are difficult to manufacture by other machining methods to increase their rigidity.Precision stampings not only require the required shape,but must also guarantee product quality.The quality indicators of precision stampings are mainly thickness reduction rate,dimensional accuracy,surface quality and physical and mechanical properties of the material after forming.So what are the factors that affect the quality of precision stampings?Xiaobian will organize the introduction for everyone.
The main reasons that affect the precision and precision of precision stampings are springback and distortion.Since the plastic deformation is always accompanied by elastic deformation,a rebound phenomenon occurs after unloading,resulting in a decrease in size and shape accuracy.
The surface quality of precision stampings mainly refers to the scratches caused during the forming process.The cause of the scratch is not only due to the unreasonable or uneven die gap,but also the rough surface of the mold,which is often caused by the adhesion of the material to the mold.For example,stainless steel drawing is easy to have this problem.
The metal does not change in volume during plastic deformation.Therefore,when the elongation type is deformed,the thickness of the plate is thinned,which directly affects the strength of the precision stamping part,so the precision terminal requiring the strength tends to limit the maximum thinning rate.
Finally,we should pay attention to whether the precision terminal die is clean and the equipment is clean.If the equipment is not clean,the finished product of the precision stamping parts will look impure and have impurities.
The above are the factors that affect the quality of precision stamping parts.Please pay attention to the use of the above.There are summary of the Czech CNC machining center,the main production(processing custom to map custom)all kinds of precision metal parts,precision CNC machining,CNC metal processing,CNC lathe processing,metal stamping,plastic injection molding,mold processing.
