What to pay attention to when using lubricants in the production of stretched parts

by:Fortuna     2021-03-06
Stretched parts are a kind of metal parts produced by stretching molds. Stretching is a kind of stamping process. Stretching parts can be regarded as a kind of stamping parts with relatively technical content, and it is more difficult to produce. Stamping and drawing processing plants need to know how to use lubricants when producing drawing parts. Precision, focusing on custom processing of precision metal drawing parts for more than 10 years, and has accumulated rich experience in drawing processing. Next, Precision will give you an analysis of what to pay attention to when using lubricants in the metal stretching process. When using lubricating oil in the processing of drawing parts, pay attention to: 1) It is not necessary to apply lubricant on the entire surface of the material. 2) Lubricant is only applied to the place where the material is in contact with the mold, and it is applied every few times. 3) It is not allowed to apply lubricant on the surface of the punch and the material in contact with the punch, because this will cause the blank to slide along the surface of the punch, which will cause the stretched part to elongate and become thinner. 4) When the thin material is stretched for the first time, there is no need to apply lubricant on the material, because the lubricant will reduce the friction between the flange and the mold and cause the formation of wrinkles. However, it is possible to apply lubricating oil to the rounded corners of the cavity of the cavity. 5) During one stretch before the shutdown, you only need to apply lubricant on the outer surface of the stretched part or the cavity of the cavity. 6) Lubricant-coated materials or blanks should be stained or contaminated, otherwise the drawing parts and drawing molds will be damaged.
