Introduction of motor housing box type drawing parts

With the development of society, the application of electronic products has become more and more extensive, and the demand for box-shaped metal stretched parts is also growing rapidly. Box-shaped stretched parts play many different roles in various fields, such as fixing and protection. The author of this article will briefly introduce some situations of the motor housing box-shaped drawing parts. The stretching of the box-shaped part of the motor housing has uneven radial tensile stress distribution, uneven distribution of deformation, and uneven distribution of tangential compressive stress. Therefore, higher requirements are put forward for the design of the box-shaped part's stretching process and the uniform mold design. . Motor housing box types are non-rotating parts, including square boxes, rectangular boxes with tolerance grades, and oval boxes. Compared with the stretching of rotating parts, the distribution of the deformation zone of the blank when the box-shaped part is stretched is so complicated that it can be stretched and formed at one time. The box shape can be divided into two categories: one is a low-box-shaped part that can be stretched and formed at one time The other type is high box-shaped parts that need to be stretched multiple times to be formed. The stretched height H is half of the width B, that is, H>0.5B. It is initially judged that the part needs to be stamped and stretched twice. The main processing procedures of the motor housing box-shaped parts include deep drawing, shaping, punching, blanking, trimming, etc. It is processed by a single-row strip material stretching progressive die method. The specific procedures are: ① punching process incision; ② primary stretching; ③ secondary stretching; ④ pressing boss; ⑤ shaping; ⑥ punching the bottom hole; ⑦ punching the side hole; ⑧ blanking. The trimming process is processed by the subsequent process.
