What needs to be paid attention to in the deep drawing process of metal stamping parts

In the deep drawing process of metal stamping parts, stamping parts processing manufacturers need to pay attention to the following points: 1. The choice of materials for metal stamping parts. Different materials for metal stamping parts have different tensile properties. The ratio of the blank diameter to the stamping diameter has an effect. The stainless steel material is controlled between 2.1 to 2.2, and the carbon steel is controlled between 2.15 to 2.5; the stainless steel material can be deep drawn for the second time after deep drawing, but it is different from carbon steel The difference in material is that stainless steel materials usually cannot be stretched to the same extent as the first time unless they are heat-treated; stainless steel materials require equipment to be 1 to 2 times stronger than carbon steel equipment. Generally speaking, deep drawing is used. Double-acting hydraulic equipment is the best; 2. Lubricant selection. In the selection of lubricating oil, two factors should be considered in the selection of lubricating oil. An oil film should be provided to prevent scratches and reduce friction, and after the deep drawing operation is completed , To be able to be easily and completely removed, it can include chlorinated or vulcanized grease or wax, heavy-duty lotion, or deep drawing soap, and water-based deep drawing stamping oil, etc.; Recommended article: Turning and twisting of stamping parts when bending The reasons and measures of the previous article: What information can stamping parts processing plants see on the scrap?
