Precision stamping parts has a wide range of applications of our daily life. Many industries have high requirements for the precision and quality of precision stamping parts. To make precision stamping parts more widely used, we should improve the quality of precision stamping parts. So how to improve the quality of precision stamping parts? The following Ming Fengqing technicians will sort it out for you.
1. Keep the surface of the convex and concave mold clean. The blank of the precision stamping part needs to be wiped clean before deep drawing to avoid that the working surface of the die or the surface of the material is not clean and mixed with debris, which damages the surface of the precision stamping part and affects the quality.
2. Adjust the proper clearance of the convex and concave dies to avoid scratches on the surface of the workpiece when the clearance is too small or uneven.
3. Polish the corner radius of the die to avoid rough round corners surface of the die and scratch the surface of the precision stamping parts when drawing.
4. Appropriately increase the hardness of the surface of the male and female molds and check the surface of the male and female molds frequently when drawing. Even if the metal scraps left are removed, because when the hardness of the male and female molds is low, the surface of the metal molds will make the drawing deep Pulled marks on precision stamped parts.
5. Use lubricants suitable for the deep-drawing process. If necessary, filter the lubricant before use to avoid impurities. If the quality of the lubricant is poor, it will increase the surface roughness of the drawn precision stamping parts, reducing the precision and quality of the stamping.
Here's how to improve the quality of precision stamping parts. To improve the quality of precision stamping parts, in addition to doing the above work, you also need to understand what factors affect the processing quality of precision stamping parts, correctly grasp the main points of precision stamping parts processing, and ensure product quality.
