With the development of society, people’s requirements for automobiles are getting higher and higher. Relatively speaking, the quality requirements for automobile hardware stamping parts are also getting higher and higher. Most automobile hardware stamping parts use high-strength plates, whether they are thick or high-strength plates. High-strength steel plates will withstand extremely high forming stresses during the stamping and forming of the workpiece, and the problem of surface strain on the workpiece cannot be avoided. Therefore, the automotive mold industry is facing higher challenges. How to solve the problem of component strain has become the mold industry’s An important topic, then how to improve the phenomenon of metal stamping parts strain? Stamping parts processing manufacturers take you to take a look; 1. Immerse the automotive metal stamping parts mold in absolute ethanol for 1-2 hours, and then perform ultrasonic treatment for 5 minutes; 2. The processed automotive stamping mold is immersed in alanine solution Soak in the medium for 2 hours, then take it out, rinse with deionized water, and dry to constant weight; 3. Place the processed automobile metal stamping parts mold in the activated carburizing medium, heat it to 750-780°C, keep it warm for 30 minutes and then cool down To 550-560℃, keep for 40min, soak in 70-80℃ quenching oil, soak for one hour, then take it out, clean the surface, dry it, heat it to 150-160℃, keep it for 2 hours; The carbon oxidation ratio in the carbon medium is 3.2-3.5; 4. Put the processed automobile stamping mold into a phosphating solution preheated to 50℃ and soak for 3.5min, remove it and rinse with water until the pH value of the water returns to medium It can be dried in a constant temperature oven for 1 hour. The temperature in the constant temperature oven is 100℃, then take it out and let it cool to room temperature naturally.
