by:Fortuna     2021-01-30
Said metal deep drawing parts, many friends are not strange, the author of many metal deep drawing parts, factory production sizes and have different shapes, also walked many detours in the process of design and production, the author today about the metal deep drawing parts summarizes some experience and we discuss together: metal deep drawing parts is a very common phenomenon, cracking due to mold edge force is small, wrinkle caused by stamping products, make it difficult to pull into the concave model cavity; And cracking is usually the radial tensile stress is too large, on the contrary, the wrinkling is tangential compressive stress is too small, caused by loss of relatively stable; Metal deep drawing parts in the process of production of blank edge burr, result in artifacts serrated edge, Blank center with the mold center, or uneven thickness of material, mold clearance uneven, can lead to product edge height not consistent; Die die fillet is too small, the material is in a state of cutting, the bottom of the workpiece easily pulled off, instead of concave die corner radius is too large, deep drawing is not finished when not pressure to the edge, wrinkle easily. Above is the author in the design and manufacture metal deep drawing parts problems often points, for your reference. 【 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
