Car deep drawing process design standard, worth learning

Said to deep drawing parts, car can think before we do through the gas tube and a series of products, when we design drawing what are the main expression contents and standards, today small take you know about the author: deep drawing process design mainly pay attention to when making craft da not rotating, work only rotating coordinates, datum as far as possible choose the geometric center of stampings; Around a common mode design, to prevent asymmetry of stamping parts, do not use mirror method to design directly, but the parts will be imported into a file to carry on the design; Mark out to give the plane normal; Deep drawing process modelling design standard: 1, in order to ensure the stamping direction pull all space shape a pull, there should be no dead Angle of the punch are not exposed to the, to ensure that the punch can all into the mold, to minimize the drawing depth difference as far as possible, to reduce the material flow and deformation distribution non-uniformity; 2, ensure the punch and the blank has good initial contact state to reduce the relative sliding, is advantageous to the blank deformation to improve the quality of stamping parts surface; 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts? Details: sharing details of stamping processing industry: precision metal stamping parts figure how to draw, please be aware that this several steps
