How to choose a suitable lubricant in the deep drawing of stamping parts?

In the deep drawing process of stamping parts, what kind of lubricant should be selected to facilitate the production of stamping parts? The stamping parts processing manufacturer will take you to take a look; 1. When the stress in the deep drawing material of the stamping part is not large, it is allowed to use the oil lubricant without filler; 2. When the stress in the stamping part material is close to the strength limit, it must Use a lubricant containing a large amount of powdered fillers (such as chalk, graphite, talc, etc., with a content of not less than 20%); 3. When the stamping parts are thinned and deepened, the lubricant is not only to reduce friction, but also to The role of cooling the mold, so dry friction should not be used. 4. When drawing conical hardware fittings, in order to increase friction resistance to reduce wrinkles, and at the same time, when it is required to continuously pass in lubricating fluid for cooling, emulsion is generally used; 5. When drawing steel hardware parts Often copper plating or phosphating treatment is used on the surface of the blank to form a layer of isolation with the stamping die, which can store liquid and has self-lubricating properties during the deep drawing process. When drawing stainless steel, high-temperature alloys and other materials with severe die sticking and strengthening, generally, the surface of the blank needs to be treated with an isolation layer.
